Since the SME Annual Conference & Expo in February, I have been

traveling to many other meetings on behalf of SME. PDAC in Toronto, Platts Coal Properties and Investments in Florida, AUSIMM’s PACRIM conference in Hong Kong where Dave Kanagy and I met with our GMPA partners, the Minnesota Section meeting and the St. Louis Section’s annual dinner. Each of these meetings has helped the focus of my year as president and provided fresh input of ideas and suggestions.

When I attended the Minnesota meeting, I flew into Minneapolis and drove to Duluth. Along the interstate a billboard caught my eye, that

asked is “Sulfide Mining Right for Minnesota?” Below that statement was www.MiningTruth.org. When I checked out the website I found it was far from the truth. Attending various presentations at the meeting, I got a feel for the issues faced in that part of the United States, which are very similar to issues I have seen in my experience and heard about in other parts of the country. The Minnesota section scheduled a session on business ethics “Promoting ethical cultures and preparing leaders to make ethical decisions” to fulfill a requirement of state licensure boards.

During a question and answer session after her presentation, I asked the presenter, Rev. Dr. Karen Schuder, how do we as engineers and scientists, who are bound by professional codes of conduct, deal with activists who use the tactics of fear, exaggeration and misinformation by making outrageous and untrue statements that are repeated so often that they begin to be accepted as fact by many in the public, and especially in the media. The answer given was somewhat circular logic, but the bottom line is that we as professionals must continue being ethical in attempting to gain the public’s trust.

The Sierra Club was started with a noble purpose. I have friends who are members probably as do many other SME members. Unfortunately, as we know, the Sierra Club, and many other groups, have engaged in successful, but unethical campaigns against virtually all new major mining projects in the United States by painting doomsday scenarios. I have questioned the ethical nature of many of their tactics. A

friend recently posted something on Facebook that the Sierra Club had originally posted, which said, “What does your activism mean to you?” with a nature photo and a quote from Alice Walker, “Activism is the rent I pay for living on the planet.”

I don’t think that the Sierra Club or any other group has an exclusive on activism. We in the mining sector are very good at “preaching to the choir.” There is nothing wrong with calling ourselves activists for our profession. In the end it is the right and ethical thing to do.

Visiting several local sections has also reinforced my thought that local sections are very important in our quest to improve the public perceptions of mining. Tim Arnold, 2016 SME President, and I are kicking off an ad hoc committee to study how SME can better serve the local sections and improve the value to members. My other challenge to the local section members is to be an activist to help us counter the widespread misinformation. Local sections are the front lines in these battles. I feel that everything SME is doing is helping in the public perception of mining arena. It is a message that I am trying to spread at each of the meetings that I attend.

Both Jessica Kogel and John Marsden have discussed this issue in their columns over the last two years, asking members to be an advocate or a voice for mining. I have to echo their suggestions and continue asking members to be engaged. Nothing like this happens overnight. The goal this year is to develop better strategies for SME and its members to use. We already have many of the tools.

Until next month, be safe out there. n

SAFETY SHARE: Across the country we have experienced the Spring tornados and rains. Many SME members are avid campers, hikers and love the outdoors. Recently, in Kentucky a young mother of three, camping with her husband and sons was killed when a large tree limb fell onto their tent during a storm. High waters made rescue difficult because of where they had placed their campsite. The take away is to check your surroundings and anticipate hazards to the best of your ability when in the outdoors.

Politics of Mining

CourttohearSouthAfrica’sblackownershipcase

Chiletoconsidernewminingregulations

SOUTH AFRICA’S government and the mining industry have not come to a consensus regarding the mandated target of 26 percent black ownership of mines and is now turning to the courts to sort it out, South African mines minister Ngoako Ramatlhodi said.

Ramatlhodi made the comments as he disclosed an interim report on the government’s assessment of how the mining industry has complied with the targets set out for it in a charter aimed at redressing the imbalances of white apartheid rule, which ended two

decades ago, Reuters reported.The main sticking point is the

industry contention that once a company is 26 percent black-owned, it has effectively complied, even if some of the black shareholders then sell out. The government says companies must retain the 26 percent ratio.

Failure to meet the targets can result in mining permits or rights being revoked.

Ramatlhodi said his ministry and the industry in the world’s top platinum producer had agreed on most

other targets laid out in the charter. The government has been auditing mining houses with an eye to charter compliance.

The minister also said about 20 percent of South Africa’s mining companies had not provided details about their compliance with the charter, but they were mostly smaller players.

Social and labor plans, training programs and the demographic composition of boards and management teams are all part of the charter. n

CHILE WILL MOVE to make changes to its environmental regulations to reduce uncertainty and encourage investment, President Michelle Bachelet announced.

Bachelet said she has appointed a commission to work over the next nine months to come up with a new environmental regulatory framework. The commission is led by the environment minister and is composed of academics and specialists in environmental, social and indigenous issues, Reuters reported.

“This commission should generate proposals to modify and modernize the system, with the aim of developing a

more expedited process,” Bachelet said.Chile’s mining sector has lost

some of its shine in recent months as a number of major projects have been stalled thanks, in large part, to environmental red tape and frequent court cases brought by increasingly active local communities.

As well as proving a costly headache for investors, such delays threaten economic growth, which is still largely reliant on mining.

Barrick Gold’s Pascua-Lama mining project, for example, was halted in 2013 after the company had already spent $5 billion, plagued by problems that included wrangling over

environmental permits.Endesa Chile’s $1.4-billion Punta

Alcalde coal-fired power project and its $9-billion HidroAysen dam joint venture are also both in doubt.

Some copper projects in Chile will not see the light of day because of their inability to comply with sustainability rules, Nelson Pizarro, chief executive of top producer Codelco, predicted.

A blocked pipeline for new projects casts doubt on projections for Chile’s medium- to long-term copper production, one of the issues that had been under discussion at the CESCO/CRU world copper conference in Santiago. n

JudgerulesinfavorofEnergyFuelsENERGY FUELS earned a legal

victory when a federal judge ruled in favor of the company’s bid to restart operations near Grand Canyon National Park, AZ.

The Havasupai Tribe and groups including the Grand Canyon Trust and the Center for Biological Diversity sued the U.S. Forest Service for allowing Energy Fuels Inc.’s Canyon Mine to reopen under a 1986 plan of operations.

They also questioned the administration’s validity test for the mine, necessary to determine whether it included economically recoverable

uranium reserves.The Canyon Mine site is within a 1

million-acre area around the national park where new mining projects are forbidden. Only valid existing claims can move forward.

It is also north of Red Butte, a cultural and religious site for the Havasupai people and other tribes. The area is a designated national cultural property.

Arizona U.S. District Judge David Campbell said the Obama administration’s actions did not violate the National Environmental Policy Act or the National Historic Preservation

Act, Greenwire reported.Campbell also ruled that groups

didn’t have standing to fight the validity determination. They may now take their cause to the U.S. Court of Appeals for the 9th Circuit.

Already there is related litigation over the Obama administration’s mining limits around the Grand Canyon after Campbell ruled in its favor last year.

The U.S. Geological Survey is studying the effects of uranium mining ahead of the Interior Department deciding whether to extend its 20-year ban on new claims. n

14Predicting the mine of the future

15Atlas suspends iron ore operations

NEWMONT MINING Corp. announced that it received approval from the U.S. Bureau of Land Management to proceed with the construction of its Long Canyon Mine in Nevada.

The mine site is less than 160 km (100 miles) from Newmont’s existing Nevada operations.

“Long Canyon is important to Newmont and Nevada as it opens a prospective new gold mining district in the state,” Newmont director of external relations Mary Korpi told Mining Engineering.

Newmont regional environmental affairs manager Dan Anderson told the Elko Daily Free Press that after the company receives the authorization to proceed from state and federal agencies “assuring the reclamation surety is in place, Newmont will start issuing contracts for initial construction activities in the coming months.”

Newmont said the first phase of the development will consist of an openpit mine and heap leach with expected gold production of 2,834 to 4,252 kg/a (100,000 to 150,000 oz/year) over an eight-year mine life. The company expects the all-in sustaining

costs of production to range between $16 and $19.30/g ($500 and $600/oz).

At current gold prices, the mine is expected to generate about $100 million annually, starting in 2017.

Construction will employ about 300 people and the mine should employ almost 300 people during operations.

The Long Canyon Mine will benefit from its proximity to existing operations said project director Gordon Mountford, “With the Long Canyon Mine being so close to existing operations, Newmont will be able to capitalize on synergies, such as transporting loaded carbon from the carbon-in-column plant to Carlin for doré production and Carlin returning stripped and regenerated carbon back to Long Canyon. Available equipment not being used at other sites will be transferred to Long Canyon. These types of synergies reduce the overall capital cost to bring Long Canyon into production that adds value to the project.”

Anderson told Mining Engineering that the mine was permitted with continual engagement and collaboration with all involved agencies.

“Permitting and NEPA analysis is a challenge with any mining project in this day and age. The Long Canyon project was no exception,” said Anderson. “Newmont developed an early permitting strategy, based on industry successes and lessons learned. The strategy was to accommodate early data collection and compilation, collaboration with key stakeholders including NGOs, and regulators to flesh out issues, concerns, opportunities and potential project alternatives.

“With a record of decision and the Nevada permits in hand, Long Canyon is poised to enter the next chapter with the development, construction and, ultimately, operation of the facility,” said Anderson.

“I’m confident that we have the engineering, orebody knowledge and community agreements in place to deliver this project safely, on time and on budget,” Gary Goldberg, president and chief executive officer of Newmont said.

The deposit is about 4.8 km (3 miles) in length and 762 m (2,500 ft) at its widest in the proposed mine plan. n

Armedrobbersmakeoffwithabout7,000ozofgoldfromElGallo1Mine

McEWEN MINING Inc. reported an armed robbery of about 198 kg (7,000 oz) of gold from a mine in Mexico, resulting in a loss that won’t be fully covered by the company’s insurance policy, The Wall Street Journal reported.

There were no injuries and no property was damaged in the robbery.

The Toronto-based miner said the robbery occurred April 7 at its El Gallo 1 Mine in Sinaloa, Mexico. An estimated 900 kg (31,700 oz) of gold-bearing concentrate — containing about 198 kg (7,000 oz) of gold — were stolen.

With gold trading around $1,200 an ounce, that would value the stolen gold around $8.4 million. The company, though, didn’t provide a loss estimate.

While the company maintains insurance against these types of incidents, McEwen said its policy wouldn’t be sufficient to cover the entire expected loss.

The theft is being investigated by Mexican authorities, McEwen said. Mexico is a big producer of gold, with some of Canada’s biggest miners present there.

Mining and processing activities were not affected. n

RioTintoreachesagreementwithMongolia;Agreement in principle paves way for second phase

MONGOLIAN PRIME minister Saikhanbileg Chimed announced that his government has reached an agreement in principle with Rio Tinto about the second phase of the Oyu Tolgoi gold and copper mine.

The two sides have been deadlocked for two years as Rio Tinto and the government clashed over a tax dispute and cost overruns during the first construction phase, The Financial Times reported.

Chimed said the agreement had been reached with investors for building on the next stage of Oyu Tolgoi and the smaller Tavan Tolgoi coking coal mine.

“The two sides have reached agreement in principle on the main points of dispute. Soon we will

officially announce these results to the international community, after bureaucratic levels finalize relevant steps,” said Chimed.

For Mongolia, much rests on resolving the Oyu Tolgoi dispute. Foreign direct investment fell last year with the downturn in commodity prices. The currency is weakening steadily and debt payments are looming.

Between March 2017 and January 2018, external debt amounting to $1.08 billion matures. Mongolia’s aim to roll this over will depend on the creditworthiness of its balance sheet.

Mongolia is not the world’s most resource-dependent economy — it is outranked by some OPEC countries — but it is among the top when it comes

to mining. The commodities boom initially lifted its economy almost 12-fold from just over $1 billion when the supercycle began a decade ago.

Negotiations with Rio Tinto, whose annual revenues are about five times Mongolia’s gross domestic product, have centered on the $6 billion underground extension to the Oyu Tolgoi copper mine. Mongolia receives no dividends from its 34-percent stake in the mine until borrowings on the original mine are repaid, which it hopes to be able to do via increased output.

But it can contribute little to financing the expansion. Rio Tinto earlier rejected a proposal for the government to take a smaller stake than its legally mandated 34 percent in return for higher royalties. n

FOLLOWING THE keynote address of the 2015 SME Annual Conference, the audience of about 2,000 people was invited to submit questions to the panelists. The audience responded with hundreds of thought-provoking questions. Moderator Peter Bryant posed a handful of questions to the panelists and, in the coming months, Mining Engineering will attempt to get answers to more of these questions.

This month, Mining Engineering will focus on the issue of big data security, a question that was asked by many audience members.

The consensus of the panel is that the ability to capture and use the mountains of data that are being generated in the modern mining industry is one of the drivers that will lead to some of the biggest changes in the industry.

“If I were to make a prediction to what I see will allow us to make that next big technological change, I would have to say its probably in the area that allows us to capture key operating data. I think this, and having the skills to turn it into valuable information is what we will see bringing about the next big change in our efficiencies, productivity and

being able to improve safety,” Dean Gehring, president and chief executive officer of Rio Tinto Minerals told Mining Engineering in an SME Thought Leaders Podcast interview.

Gwenne Hennricks, vice president, product development and global technology for Caterpillar, said, “As data becomes more available, as we put more sensors on the equipment, as we take advantage of social media input and crowd sourcing capabilities that the Internet affords us, we will be able to tap into brilliant ideas from a huge population of essentially anyone in the world. And by coupling that with compute power that is dramatically increasing and reducing its cost at the same time, we will be able to take advantage of huge amounts of data and turn that into very useful information very quickly.”

However, as with any change, there are challenges. Among those that come from having the ability to drive a 400-ton haul truck from a command center hundreds of miles away while collecting real time data is the challenge to protect that data.

“It’s crucial that we maintain security of the information that is generated by the equipment for a

number of reasons. Some is safety related and some is in protecting information that rightfully belongs to customers or individuals, so security is a primary focus when handling all of the information,” Hennricks told Mining Engineering in an SME Thought Leaders Podcast.

Another concern is how the data is collected will be shared.

“What social media has taught us about data is if its interesting and if its electronically available it will be shared around about the world,” Gehring told Mining Engineering.

With that, Gehring cautioned, “I believe our data will become increasingly available to public and I think this is going to largely be driven by evolving regulatory requirements. If real time compliance information is shared without context I think we are going to find ourselves on our backfoot trying to explain the information that is being shared and by that time its too late.”

Gehring said that the mining industry must engage it’s stakeholders at a high and continuous level, build trust and provide context to the data.

“The shift in transparency is inevitable and it’s only a threat if we choose to ignore it,” said Gehring. n

SIEMENS HAS selected Molycorp Inc. to supply rare earth materials over the next 10 years from its Mountain Pass, CA facility for incorporation into Siemens’ high-efficiency, direct-drive wind turbine generators. Molycorp will supply rare earth materials to Shin-Etsu Chemical Co., Ltd., which will produce the rare earth magnets Siemens intends to utilize in its wind turbines.

Siemens officials noted that key factors in choosing Molycorp

MolycorppickedtosupplyREEforSiemens;Rare-earth elements for wind turbines will come from mine in California

were Molycorp’s ability to provide greater global diversification and reliability to its supply chain, as well as the environmental and process innovations Molycorp has built into its Mountain Pass rare-earth facility. Among those innovations are the facility’s ability to recycle water, regenerate the chemical reagents needed in rare-earth production, generate power from a high-efficiency natural gas cogeneration power plant and dispose of mine tailings through

an innovative paste tailings system.Siemens officials said that the

magnets to be used in its direct drive wind turbines will contain reduced levels of heavy rare-earth elements (HREEs), such as dysprosium. In collaboration with Siemens Wind Power, Molycorp and Shin-Etsu will improve the magnet material to reach zero HREEs, Siemens said. At the same time, Siemens added, supply- chain reliability will be increased and costs will be reduced. n

AS THE 2015 SME Minnesota Conference prepared to kick off in Duluth, MN, troubling news about the global iron ore industry was breaking in Australia, as Atlas Iron Ltd. announced that it was shuttering all of its mines and exports to Asia.

The Wall Street Journal reported that as recently as 2011, Atlas was worth nearly A$4 billion (US$3.1 billion), but the collapse of iron ore prices made it the most recent casualty of a 30-percent decline in prices this year.

Arrium Ltd. was forced to shutter one of its two iron ore mines in Australia, and Cliffs Natural Resources suspended a mine in Canada as it restructures it’s U.S.

Atlas Iron suspends operations in Australia;Iron ore sector continues to struggle with low prices

business to focus on domestic iron ore sales rather than competing in the seaborne market.

Even major producers such as Rio Tinto Plc, have been slashing costs and jobs as it grapples with the deepening market downturn.

Fortescue Metals Group Ltd., the world’s fourth-largest iron ore exporter, was forced to scrap a planned debt sale because it couldn’t agree on terms with investors amid a sour outlook for the commodity.

In February, Atlas Iron reported a more than A $1-billion net loss for its fiscal first half, swinging from a profit a year earlier, as it wrote down the value of its mining assets.

At the time, executives vowed they

were working hard to slash operating costs to safeguard earnings.

But iron ore prices have raced lower faster than many companies can cut costs. The price of iron ore, a key ingredient in steelmaking, slumped as low as US$46.70/t ($42.32/st), weighed by ballooning supplies of the raw material as China’s economy cools.

Some of the world’s biggest miners, including Rio Tinto and BHP Billiton Ltd., have been aggressively expanding their operations in the Pilbara iron ore mining hub of northwest Australia, completing major mine and infrastructure projects planned when the market was booming. Iron ore traded as high as US$190/t ($172/st) in 2011. n

Exploration Reviewby D.R. Wilburn, K.A. Stanley and N.A. Karl, National Minerals Information Center, U.S. Geological Survey

This summary of international mineral exploration activities for the year 2014

draws upon information from industry sources, published literature and specialists in the U.S. Geological Survey (USGS) National Minerals Information Center. The summary provides data on exploration budgets by region and mineral commodity, identifies significant mineral discoveries and areas of mineral exploration, discusses government programs affecting the mineral exploration industry and presents

analyses of exploration activities performed by the mineral industry.

Three types of information are reported and analyzed in this annual review of international exploration: 1) budgetary statistics expressed in U.S. current dollars provided by SNL Metals & Mining (SNL) of Charlottesville, VA; 2) regional and site-specific exploration activities that took place in 2014 as compiled by the USGS and 3) regional events that affected exploration activities including economic, social and political conditions, which were derived from published sources and discussions with USGS and industry specialists. Commodity and regional compilations are presented in this summary. Because multiple sources are used to develop these compilations, statistics may differ depending on the source and type of data that are being reported.

The SNL data summarize planned company budgets for worldwide exploration activities in

2014 for 19 nonfuel mineral commodities based on company surveys. Research focused on precious metals (gold, platinum-group metals and silver), base metals (cobalt, copper, lead, molybdenum, nickel, tin and zinc), bulk commodities (iron ore, phosphate and potash), and specialty mineral commodities (diamond, lithium, niobium, rare-earth elements, tantalum and uranium). Information on uranium exploration activities was included for the first time in 2007. Data on lithium, niobium, phosphate, potash, rare-earth elements and tantalum were compiled for the first time in 2010 because of their increased significance. Since 1999, companies with exploration budgets of $100,000 and greater were included in the SNL compilations. SNL budget estimates exclude bauxite, coal and oil and gas. Exploration budget estimates for iron ore have been compiled since 2011 but reported separately. The 2014 SNL company survey is reported by SNL to cover an estimated 95 percent of the world’s nonferrous, nonfuel mineral exploration budgets. The 5 percent that is not covered includes companies that chose not to participate in the SNL survey, private companies that do not publish their budget data, and government-funded exploration activities.

USGS data compilations and analyses are based on information provided by USGS mineral commodity and country specialists, as well as industry contacts and published in trade journals. The USGS compilations summarize exploration site data collected for more than 80 minerals and materials, with a focus on nonfuel minerals including base metals, diamond and precious metals. Iron ore and uranium were included in the USGS analysis after 2007. The USGS analyzed available information to assess the level of exploration activity in 2014 and to report trends in mineral exploration activity for the period 2004 through 2014. This analysis identifies where mineral exploration is taking place by commodity and region, assesses the intensity of activity that is taking place in each region for selected mineral commodities, and determines those factors that most affect changes in exploration activity.

Certain limitations apply when comparing estimates or evaluating the magnitude of regional changes from year to year because as worldwide exploration allocations have changed, so too have factors such as energy, labor, material and service costs associated with mineral exploration. Consequently, an exploration budget of $1 million allocated in 2014 would generally yield

less exploration activity than a corresponding budget in 2004. The global economic climate and fluctuations in currency exchange rates and the value of trading currencies over time also can influence the business pattern of companies conducting business in other countries. Unless otherwise specified, this report expresses worldwide exploration activity in U.S. current dollars to simplify comparisons by commodity and region. The level of exploration investment also may be influenced by the scale of the planned operation. Development of a large-scale operation usually requires a greater exploration investment than a small-scale operation with a shorter project life.

Temporal interpretations of the SNL exploration data, such as trend analyses, are limited by changes in survey parameters. Because the sample of exploration and mining companies surveyed by SNL has changed over the years, companies included in the survey have changed on a year-to-year basis. In addition, fluctuation of currency exchange rates affects the relative value of company budget estimates from year to year. Also, mineral commodity and country coverage have differed from year to year and corporate restructuring within the mining industry has taken place. Industry coverage varies from year to year because the number of respondents to the SNL survey changes over time. In general, the number has increased for the more recent surveys.

2014 global mineral exploration activity and trends from 2004 through 2014

According to SNL, the total estimated worldwide budget allocation for nonferrous

mineral exploration decreased by 26 percent in 2014 to about $10.7 billion (on the basis of data from 1,961 companies when iron ore is excluded) from the 2013 budget allocation of about $14.4 billion (based on 2,129 companies, excluding iron ore). The exploration budget for iron ore projects, first compiled in 2011, was not included in the nonferrous budget data. Continued market instability and the reduction in available funding for mining projects in 2014 resulted in exploration budget cutbacks and reduced the number of junior companies conducting minerals exploration.

SNL annual survey estimates reflect budgeted expenditures, rather than actual dollars spent, and reflect an estimated 95 percent of worldwide exploration. When SNL includes estimates for exploration budgets for nonrespondents, the global nonferrous exploration budget for 2014 is estimated by SNL at about $11.4 billion. Exploration conducted by government entities in locations such as China may not be included in SNL estimates.

Competing demand for assaying, drilling and geophysical services, changing fuel and labor costs, higher taxes and environmental costs and a decreasing skilled labor force have resulted in an increase in the total cost of exploration during the past decade. Exploration cost increases, combined with lower prices for many mineral commodities experienced during the past several years have reduced investor interest and the level of exploration activity. Even if the overall exploration expenditure remains stable, increased exploration costs have reduced the effective amount of exploration activity that can be conducted at a site over time.

Exploration Review


Exploration Review

Figure 1 shows the 2014 worldwide nonferrous minerals exploration budgets allocated by region, based on SNL data. SNL “regions” reflect a mixture of individual countries, continents and other groupings, but they are reported consistently on an annual basis and provide a means of assessing the flow of budgeted exploration expenditures from year to year. The 2014 nonferrous exploration budgets in decreasing budget order were Latin America, Africa, Canada, Australia, the United States and the Pacific region. According to SNL data, China and Russia accounted for about 56 percent of the Rest of World region budget total. The exploration budget in 2014 in all regions was lower than the corresponding budget in 2013. The largest decreases by current dollar percentage took place in the Pacific region (38-percent decrease) and Australia (34-percent decrease); the smallest decreases took place in Canada (22-percent decrease) and Latin America (26-percent decrease). Latin America remained the region with the largest mineral exploration budget, expressed either in current dollars or percent of the global exploration budget.

For 2014, information for about 2,500 exploration sites was gathered by USGS specialists from published literature and industry sources. The regional distribution of these exploration targets is represented in Fig. 2 by principal commodity target, based on the number of projects reported for each region. Canada remained the top destination in terms of active exploration sites in 2014, followed by Australia, Latin America, Rest of World and Africa. For ease of comparison within this study, the USGS used the SNL regional classification when grouping site data.

1As defined by SNL, Latin America includes countries in the Caribbean, Central America, Mexico, and South America. The Pacific region includes Fiji, Indonesia, Japan, Laos, Malaysia, New Caledonia, New Zealand, Papua New Guinea, Philippines, Solomon Islands, Thailand, Vanuatu, and Vietnam. Africa includes countries on the African subcontinent. The Commonwealth of Independent States (CIS) includes Azerbaijan, Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Uzbekistan, and Ukraine. The Rest of the World includes China, Europe, India and Pakistan, the Middle East, and Russia and the other republics of the Commonwealth of Independent States. Australia, Canada, and the United States are treated separately.

Thus, regional classifications may vary from other USGS publications. The number of sites that are actively being explored does not correlate directly with exploration budget estimates, but both are indicators of activity in the region of interest.

Figure 3 summarizes SNL budget data by region for the period 2004 through 2014 in terms of current dollars and percent of the world exploration budget. The top chart of Fig. 3 shows that the planned exploration budget level (expressed in current dollars) for 2014 decreased from the 2013 budget level in all regions of the world. The largest current dollar regional budget reduction from 2013 to 2014 took place in Latin America, followed by Africa. The regions with the smallest decrease in exploration budgets were the United States and the Rest of World region (including China and India, countries in the Commonwealth of Independent States) (including Russia) Europe and the Middle East). The middle chart of Fig. 3 shows the trend in global exploration budgets in terms of both current dollars and constant dollars. Figure 3 (bottom chart) shows that the percentage of the world exploration budget increased in 2014 from 2013 for Canada, Latin America and Rest of World in relative terms, even though the total exploration budget for these regions was lower in 2014 than in 2013.

The SNL mineral exploration survey data

suggest that, since 2004, the amount of the total global exploration budget attributed to mine-site exploration has generally increased, while early-stage (greenfield) exploration has decreased to a level less than that for mine-site exploration in 2014. The amount attributed to late-stage exploration increased from 2004 to 2006, and mine-site exploration from 2006 through 2009, as larger companies shifted their exploration focus toward advanced-stage projects or mine site projects as a less expensive means of replacing or adding reserves. The budget estimate for early stage exploration was 32 percent lower in 2014 than that reported for 2013, corresponding to a level last seen during the economic downturn that took place in 2008-2009. Traditionally, major companies leave greenfield exploration to junior companies. In 2014, however, many junior companies had difficulty securing sufficient financing to conduct extensive exploration. Consequently, larger companies contributed a greater budget to greenfield exploration, accounting for about 40 percent of the 2014 early-stage exploration allocation.

Changing mineral commodity prices (particularly for copper, gold, nickel and silver), fluctuating currency exchange rates and increased exploration costs were among the considerations used by companies in determining exploration targets and development plans for 2014. Low

Exploration Review

commodity prices make it more difficult for smaller junior companies to obtain financing in a tight economy, so companies have been focusing available capital on fewer exploration projects. Fewer large deposits have been found because of reduced exploration expenditures, and those that have been identified have required greater exploration expenditures because of their remote location or increasing depth of occurrence. The number of viable, large-scale assets considered available for development is likely to decrease in the near term. These observations coincide with recent studies that suggest that the discovery rate and ore grades for some mineral commodities, especially gold, have been declining steadily since 1999.

Recent and anticipated mineral commodity prices contribute to exploration budget development and the amount of activity planned by mineral exploration companies. Table 1 shows the average annual prices for selected metals for the years 2004 through 2014. However, because of metal price variation, reporting just the average annual prices does not provide enough information to assess the effect of multi-year price changes on the level of exploration. Figure 4 shows the annual indexed prices in 2004 constant U.S. dollars for selected (a) precious metals, (b) base metals and (c) other selected mineral commodities for 2004 to 2014. Using constant dollar values based on the Consumer Price Index reduces the effects of inflation on prices of mineral commodities being considered over time. When expressed in terms of current dollars, the average 2014 price for eight of the 10 selected commodities was higher in 2014 that the 2004-2014 average price of that commodity. However, when expressed in terms of constant dollars, the average price for eight of the 10 selected commodities was lower in 2014 than the 2004-2014 average price of that commodity.

The average prices for copper and zinc have remained relatively stable for the period, when expressed in terms of constant dollars.

As shown in Fig. 4, the 2014 average constant dollar price for seven of the 10 selected commodities was lower in 2014 than in the two previous years. Of the commodities selected for evaluation, only the average constant-dollar prices for nickel, palladium and zinc were higher in 2014 than in 2013. In spite of generally lower prices in 2014, the 2014 average constant dollar price for gold was 16 percent higher than the average 2004-2014 constant dollar price for gold. Similarly, the 2014 constant dollar palladium price was 60 percent higher. The 2014 average constant dollar uranium yellow cake price was 37 percent lower than the average 2004-2014 constant dollar price, the 2014 constant dollar nickel price was 24

percent lower, the 2014 constant dollar platinum price was 8 percent lower, the 2014 constant dollar zinc price was 7 percent lower, the 2014 constant dollar price for copper was 6 percent lower and the 2014 constant dollar price for neodymium oxide was 5 percent lower. The 2014 constant dollar prices for lead and silver were close to their average 2004-2014 constant dollar prices.

Historical and future trends of metals prices are considered when determining where and what commodity target to spend available capital on exploration and development. During the period of increasing gold prices from 2005 through 2012, the major gold miners increased the recovery from lower grade ore and were able to maintain a satisfactory profit level, and some exploration companies re-evaluated deposits with historically lower ore grades. The higher price permitted the company to expand the “reserve” of the deposit. In 2014, however, the average gold price was 24 percent lower than the average gold price in 2012. This forced some producers to lower the prices they used to calculate year-end 2014 reserves in order to comply with regulator’s definitions of what defines an allowable reserve estimate, thus reducing the reserve estimate. In response to low gold prices, some companies are reducing costs by cutting capital expenditures and exploration spending, reducing overhead costs, and scaling back mine plans to focus on extracting higher-grade ore. Exploration activity at some sites with lower gold grades is being curtailed and some marginal mines are being closed, at least temporarily, until the gold price increases.

Currency movements were an important consideration for the minerals exploration and mining sector in 2014. The U.S. dollar strengthened against all other major currencies in 2014 for the first time this century. A strong U.S. dollar has a negative impact on international investment returns and increases the costs associated with foreign projects that purchase goods or supplies

using U.S. dollars. It also may increase the relative costs of exploration in the United States when compared to other regions, as labor and material costs are incurred in U.S. dollars.

Ernst & Young Global Ltd. estimated the greatest business risks for the mining and minerals exploration industry in 2014, in declining order of importance, as productivity, capital sourcing, the social license to operate, capital projects, resource nationalism, price and currency volatility, infrastructure access, benefit sharing, labor issues and access to water and energy. Productivity in the mining

sector reportedly has been declining on a volume basis since 2000. A primary cause for the apparent decline in productivity was the fast pace in which mining companies expanded during the 2000s.

During the past few years, the declining prices of some metals, massive write-offs and reduced earnings have made investors wary of the mining sector. Global demand for some metals has been affected by the recent global recession and a reduction in Chinese consumption for these metals. While the major companies and junior companies have lowered their planned exploration spending, restricted access to investor funds have affected the junior companies more than larger companies, which have other sources of revenue. Data suggest that the junior sector share of exploration budgets decreased to a 12-year low of 32 percent in 2014 while the major company share increased to an 11-year high of about 49 percent. Intermediate company share was reported to be about 11 percent in 2014. Improved reporting by Chinese entities has shown an increased share for government-controlled companies to more than 8 percent of the exploration budget globally, as these companies are expanding their exploration activity beyond China.

The lack of available capital targeted for preproduction assets has made it difficult for junior companies to obtain sufficient capital to sustain exploration activities. One study suggests that one in 10 junior miners may go into administration, and a further 16 percent are likely to halt operations temporarily. There was a general trend in declining merger and acquisition activity in 2014, with the number declining from 702 in 2013 to 544 in 2014 and the value of these deals decreasing 49 percent from $87.3 billion in 2013 to $44.6 billion in 2014, according to Ernst & Young Global. Some junior companies are turning to engineering and construction companies, many from China and the Republic of Korea, or private equity investment as potential sources of funding. Some major

Exploration Review

companies are looking internally for growth opportunities while others are divesting some holdings to separate unprofitable assets. BHP Billiton Ltd., Vale S.A. and Yamana Gold Inc. have all announced plans to separate or sell off noncore assets.

Resource nationalism is a term used to describe policies initiated by some countries to balance promoting investment and maximizing in-country benefits. Resource nationalism can take many forms, including imposing a resource tax, amending royalty or tax rates, establishing greater controls on foreign participation, establishing state ownership or control, or mandating in-country value-added processing and/or limiting exports. The ban on exports of mined ores imposed in Indonesia in January 2014, in an effort to encourage in-country processing, is one example of resource nationalism. Indonesia is a leading producer of nickel laterite ore and bauxite. The legislation resulted in a ban on metal ore and concentrate exports from Indonesia. Anticipation of reduced nickel supply resulting from the ban led to an increase in the nickel price during 2014 and increases in nickel global inventories and stocks. Increased nickel laterite production from the Philippines reduced the gap in supply from Indonesia. China, a leading consumer of Indonesian ores, has begun to source its bauxite from other countries and built new processing facilities capable of handling lower-grade material from other countries. Similarly, China has been blending nickel ore for its stockpiles with lower-grade nickel ore from the Philippines used in nickel pig iron production.

Since 2000, the global landscape for mineral exploration and development has changed. At the end of the 20th century, the bulk of global mineral exploration was conducted by Australian, Canadian and U.S. companies. Companies headquartered in these countries continue to explore globally and generated the greatest exploration budget in 2014. However, the share of companies headquartered in these three countries has declined, accounting for about half of the global exploration budget in 2014 compared to about two-thirds of the exploration budget in 2005. Exploration and mining investment has shifted from these traditional jurisdictions to virtually all countries. The term BRIC commonly refers to the grouping of several countries with growing economies (Brazil, Russia, India and China). The exploration budget for the BRIC countries (excluding India) has increased from about $300 million in 2005 to more than $1.7 billion in 2014. In percentage

terms, exploration in these countries increased from less than 7 percent of the global exploration budget in 2005 to more than 12 percent of the global budget in 2014. Figure 5 shows this global trend using SNL budget estimates. However, Fig. 5 does not include India, which was not reported by SNL for all years from 2005 through 2014. In addition, SNL data for China varies significantly from data reported by Chinese sources for metal and nonmetal mineral exploration (excluding oil and gas). This set of data may be more inclusive than data for China compiled by SNL, as it reportedly includes exploration expenditures for a wider range of mineral commodities from both private and public entities. When these factors are considered, the increase in the contribution of BRIC countries is greater than that shown in Fig. 5 but the overall trend remains the same.

Many exploration projects are becoming increasingly more costly and difficult to develop. There is a growing trend toward exploring for deeper deposits as shallower reserves are depleted. The Resolution copper deposit in Arizona, the Cukaru Peki copper deposit in Serbia and the Cascabel copper deposit in Ecuador are all examples of high-grade ore deposits that are deeper extensions of active or previously mined sites. In South Africa, older, high-cost mines that do not lend themselves to mechanization are being phased out in favor of highly mechanized mines. In Australia, exploration companies are looking for high-grade deposits under covered terrain. Although the country’s historical success rate for locating minable deposits in covered terrain has not been high, depletion of shallow deposits is driving explorationists to look in areas that have traditionally been more cost intensive and technically challenging.

Competing demand for energy and water have increased risks related to energy and water access. Mining companies spent $11.9 billion on water infrastructure in 2013, a 250-percent increase from

2009. As exploration is taking place in more remote locations, countries such as Chile, Mongolia, Peru and South Africa are focusing on increasing access to or development of energy and water resources. Some mining companies are considering greater use of renewable energy as part of a strategy to lock in long-term energy prices and minimize exposure to regulatory changes, market pricing, and the rising demand for energy.

As global demand for natural resources continues to increase and viable land-based resources decline, there is increasing attention to exploring the ocean floor for its mineral potential.

Figure 7

In 2007, Nautilus Minerals began exploration for massive sulfides off the coast of Papua New Guinea and a joint venture was formed in 2014 between the company and the nominee of the Independent State of Papua New Guinea to develop the Solwara 1 project site. There has been an increase in the number of exploration contract applications to the International Seabed Authority (ISA), an autonomous international organization established under 1994 provisions of the United Nations Convention on the Law of the Sea. In 2010, only six projects were ongoing in international waters; by 2014, 26 project


applications were expected to be received by the ISA. In 2014, the Japan Oil, Gas, and Metals National Corp (JOGMEC) announced the discovery of a hydrothermal mineral deposit off the coast of Okinawa Prefecture near Japan. A decision by New Zealand’s Environmental Protection Authority to oppose a deep sea mining venture off its coasts may reduce interest in exploring for mineral deposits in the region.

Exploration activity by mineral commodityThe amount budgeted for gold exploration

($4.6 billion) based on SNL data for 2014 is 31

percent lower than that budgeted for gold in 2013. Figure 6 illustrates the 2010-2014 global percent share distribution of reported mineral exploration budget estimates by mineral commodity grouping (excluding uranium). Figure 6 shows that the percent share attributed to global gold exploration relative to exploration for all nonferrous minerals has been decreasing since 2011. In terms of percentage of worldwide nonferrous exploration budget, exploration for gold accounted for 45 percent in 2014 and 48 percent in 2013. This variation may be an artifact of survey response or other factors in light of generally lower gold

prices over the period. Latin America remains the leading region for gold exploration based on SNL data, accounting for more than a quarter of gold budget allocations. Other principal locations for gold exploration in 2014, in descending order by 2014 budget, are Canada, Australia, the United States, Mexico, China, Russia, Colombia, Peru, Burkina Faso, Chile, Papua New Guinea, Brazil and Indonesia.

Exploration budgets for base-metal projects decreased 21 percent to $3.7 billion in 2014 from $4.7 billion in 2013. In terms of percentage of total worldwide nonferrous exploration budget, however, the estimated base-metal exploration budget increased to 36 percent of the total in 2014. The percent allocation for base-metal exploration remained relatively stable from 2010 through 2011, and increased from 2013 through 2014. Exploration for copper accounted for more than 70 percent of the base-metal budget for 2014. Latin America retained the greatest percent share for base metals exploration of the global budget, in spite of a significant decline in budget allocation. Countries with the largest exploration budget for copper in 2014, in declining order by budget, were Chile, Australia, Peru, the Democratic Republic of the Congo, the United States, Canada, China, Zambia, Mexico and Brazil. Countries with the largest exploration budget for zinc/lead in 2014 were China, Canada, Mexico, Australia, Peru, the Democratic Republic of the Congo, Sweden, India, Ireland and the United States. Countries with the largest exploration budget for nickel in 2014 were Australia, Canada, Russia, Indonesia, China, the United States, Finland, Brazil, Tanzania and the Philippines.

The budget for diamond exploration decreased 9 percent in 2014 in current dollar terms from 2013, the smallest percentage decline of all commodities monitored by SNL. In current dollar terms, the diamond exploration budget of about $400 million in 2014 was about 44 percent of the budget for diamond in 2008 and represented about 4.4 percent of the global exploration budget, slightly higher than its share in 2013. Principal locations for diamond exploration in 2014, in declining order by budget, were Russia, Canada, Angola, Botswana and South Africa.

Based on exploration budget estimates, the 2014 estimate for platinum-group metals (PGM) of about $200 million was up 50 percent from the 2013 budget estimate of more than $100 million, and represented 1.7 percent of the global exploration budget for 2014. Principal areas for planned PGM exploration in 2014 were South Africa, Canada and Russia, in descending order by 2014 budget. Strikes taking place at several South African mines led to concern over mineral

supply, as demand from the automotive industry for catalytic converters was strong in 2014. The World Platinum Investment Council projected an 885 kt (975,500 st) deficit in platinum supply for 2014. A portion of this projected deficit may be offset by palladium substitution.

The estimated 2014 global budget for other mineral commodity targets was 28 percent lower ($1.3 billion) in 2014 than the $1.8 billion reported for 2013. Mineral commodities considered include heavy-mineral sands, lithium, molybdenum, niobium, phosphate, potash, rare-earth elements (REE), silver, tantalum, tin and tungsten. Exploration for lithium, potash, and REE has increased as demand for and concerns related to supply of these commodities has risen. Concern about China being the sole source of supply and its policy (as of 2014) of issuing export quotas for REE has led to increased exploration for REE at projects in Australia, Canada, South Africa and the United States. Principal locations for exploration in 2014 for minerals other than those listed above include Canada, Mexico, Australia, China, Brazil, Peru, the United States, Argentina and Chile, in declining order by 2014 budget.

The budget estimate for uranium exploration decreased from about $616 million in 2013 to about $504 million in 2014. The global nuclear industry has not yet returned to its pre-Fukushima level, as safety concerns remain high. Principal locations for exploration of uranium in 2014, in declining order by 2014 budget, include Canada, Australia, Kazakhstan, Mongolia, Niger, Namibia and the United States.

Based on global exploration site data compiled by the USGS, gold was the principal target at 41 percent of the sites explored in 2014; copper was the target at 19 percent of the sites and iron ore, silver, uranium and zinc each were the target at 5 percent of the sites (20 percent combined); nickel at 4 percent of the sites; and other minerals represented the remaining 16 percent of the sites. The SNL and USGS data support the conclusion that there is continued interest in exploration for lithium, potash and REE, but the number of projects exploring for these commodities has declined from the 2012 peak.

2014 exploration highlightsTable 2 presents selected noteworthy

exploration sites based on the amount of exploration activity conducted at the sites in 2014. Data were not verified by the USGS. Where resource data were not released, the site was considered noteworthy by the authors based on the level of exploration activity or regional significance. A combined total of more than 4.5 million m (2,796 miles) of drilling took place in


Exploration Review

2013 on the sites included in Table 2. The following criteria were used as a basis for site inclusion:

• The high level of exploration interest at a site, determined either by intensity of drilling activity or level of capital investment. When drilling was used as the principal indicator, a site qualified if a minimum of 15,000 m (49,200 ft) of drilling (usually a combination of diamond or reverse-circulation drilling) took place during 2014 along with ancillary exploration activities; where budget was used as the principal indicator, a site qualified if a 2014 budget of at least $4 million was planned and executed for exploration and drilling activities. These criteria may eliminate early-stage projects (where the level of drilling was below cutoff) or development projects (where planned expenditures include costs for development or infrastructure). Owing to the decrease in exploration activity in 2014, the minimum drilling cutoff was reduced from 20,000 m (65,600 ft) in 2012 to 15,000 m (49,200 m) in 2014 and the minimum expenditure cutoff was reduced from $8 million in 2013 to $4 million in 2014.

• The magnitude of resource delineated when compared to prior resource estimates.

• The high potential of near-term development, based upon reported tonnage and grade estimates derived from company announcements.

• The regional significance of an activity based on economic or social needs of the locality.

• The project reflects an emerging source of mineral supply as a result of advances in extraction technology.

Sites where significant exploration activity and expenditures took place prior to 2014 were not included in Table 2 if the reported level of 2014 activity did not meet the selection criteria. Except where indicated, similar criteria have been applied to previous exploration summaries reported annually in the USGS Minerals Yearbook series and in exploration summary articles published in Mining Engineering.

As reported in Table 2, gold continued to be the commodity generating the greatest exploration intensity by number of projects based on the list of noteworthy exploration sites in 2014. Of the sites selected for Table 2, the primary targets were: (1) gold or silver at 76 percent of the sites, (2)

base metals at 9 percent of the sites, (3) uranium at 5 percent of the sites, (4) PGMs at 3 percent of the sites and (5) other mineral commodities at 7 percent of the sites. Determination of the primary commodity was based on consideration of commodity value of the contained resource at each site.

The estimated resources reported in Table 2 reflect various stages of verification, different methodologies and multiple sources of information based on company data. Should these reserves/resources be confirmed, however, they would add about 500 Mt (550 million st) of iron, 13 Mt (14.3 million st) of copper, about 5 Mt (5.5 million st) of lead and zinc, 2 Mt (2.2 million st) of niobium, 1.6 Mt (1.7 million st) of nickel, 430 kt (475,000 st) of combined rare-earth oxides, 230 kt (253,000 st) of U3O8, 200 kt (220,000 st) of molybdenum, 21 kt (670 million oz) of silver, 5.6 kt (180 million oz) of gold, and 1.7 kt (54 million oz) of PGM to the identified world resources for these mineral commodities. It is likely, however, baring a dramatic sustained increase in commodity prices, that only a portion of the listed resources may be converted to reserves based on future exploration activity.

Figure 7 is a plot of the locations of those sites included in Table 2. The site numbers shown in Table 2 are used to identify the locations in Fig. 7. Sites have been classified by their primary commodity target.

The cost of doing business in a country can change based on many factors, including economic and environmental conditions, legislative actions, political activity and social receptivity to mining. These factors all determine the perceived risk profiles of a country. The Fraser Institute of British Columbia, Canada, annually publishes a survey assessing the effects of perceived “investment attractiveness,” which combines geologic attractiveness and the perceptions of public policy on attitudes toward exploration investment around the world. The 2014 survey (published February 2015) includes data from 485 respondent companies with an aggregated exploration budget of US$2.7 billion in 2014, down from $3.2 billion in 2013.

According to the 2014 Fraser Institute Survey, the top 10 destinations for mineral exploration based on overall investment attractiveness in 2014, listed in descending order, were Finland, Saskatchewan (Canada), Nevada (United States), Manitoba (Canada), Western Australia (Australia), Quebec (Canada), Wyoming (United States), Newfoundland & Labrador (Canada), Yukon Territory (Canada) and Alaska (United States). Greenland and Sweden were including in the top 10 list for 2013, but fell out of the


Exploration Review

top 10 in list in 2014. The top 10 destinations for mineral exploration based on their mineral potential independent of policy restrictions and listed in descending order, were Yukon Territory (Canada), Nevada (United States), Alaska (United States), Northwest Territories (Canada), Manitoba (Canada), Chile, Peru, Western Australia (Australia), Idaho (United States) and Quebec (Canada). The top 10 destinations for mineral exploration based solely on policy attractiveness and listed in descending order, were Ireland, Finland, Alberta (Canada), Sweden, New Brunswick (Canada), Saskatchewan (Canada), Newfoundland & Labrador (Canada), Wyoming (United States), Manitoba (Canada) and Western Australia.

Exploration activity and related legislation by region

Exploration-related activities and events within each region are summarized. The order of regional and country discussions is based on the amount budgeted for exploration in 2014 from highest to lowest. Areas not included in the regions discussed have been aggregated as Rest of World and are discussed separately at the end of this section.

Latin America. Latin America continued its leading position as a destination for exploration activity based on exploration budget data collected by SNL since 1994, but was listed third after Canada and Australia by the USGS when the number of active sites was considered. On the basis of data compiled for this review by the USGS, Latin American countries with the greatest exploration activity, in descending order by number of sites for which data were compiled, were Mexico (136), Peru (93), Chile (79), Brazil (61), Argentina (39) and Colombia (16).

Approximately 57 percent of the deposits actively explored in 2014 in Latin America contained gold or silver and 34 percent contained base metals, or some combination of precious and base metals based on the sites considered in the USGS compilation. Activity in 2014 was primarily used to further define early-stage discoveries (47 percent), conduct exploration at a producing site (29 percent), conduct prefeasibility and feasibility studies of economically promising prospects (13 percent) and further explore deposits under development (11 percent).

Latin America has been considered the leading region for mineral exploration by many companies for the past decade owing to its promising geology, its long history of world-class discoveries, the perception of its mineral policies, and its successful historical record of mineral

production and development. Although the overall trend of budget expenditures has declined for all regions since 2012, Latin America still remains the leading region for exploration with a regional budget close to $3 billion in 2014. The amount of drilling also has declined since 2012, following the worldwide trend. Lower commodity prices and reduced capital for mineral exploration are starting to affect exploration activities for many South American countries.

Argentina’s exploration investment level has declined about 50 percent over the past two years owing to a combination of domestic factors and the global economy, resulting in the suspension of some exploration activity that had previously been announced.

In 2014, the Bolivian government passed a new mining law that restricts mining cooperatives from partnering with foreign or domestic private companies. Also included within the law is a stipulation that bans private firms from registering minerals as property, thus hindering the use of these resources as collateral for loans or claimed as assets in the acquisition of new financing in the development of projects. In response to public unrest, revisions to the law are being considered.

Currently, there are 115 mining exploration companies developing 321 projects in Brazil, according to the data compiled by minerals production agency DNPM. Gold projects account for more than one-third (127) of the total. The president of Brazil has proposed legislative changes to the mining sector including the creation of a new mining regulator, the creation of a single mining license in place of the current exploration and exploitation licenses, and raising royalty payments to 4 percent on gross revenues from 0.2-3 percent of net revenues. The outlook for this proposed legislation is questionable as a new presidential cabinet is being formed.

Energy availability and water scarcity have become significant issues in Chile, as the country is on track to double its energy demand between now and 2025, according to the state Copper Commission. This has caused many companies to find new ways of powering their projects so that development can proceed. Chile’s mining sector energy operating costs represent roughly 14 percent of total production costs, equivalent to 27 percent per pound of metal, the highest level since 2000. There are many different types of renewable resources being developed in Chile to improve the availability of these resources. Wind, solar thermoelectric and hydroelectric plants are among the energy sources currently being used and developed.

Chile’s mining industry currently consumes about 5 percent of the fresh water in the country,

and this figure is expected to increase by 50 percent if expansion plans by the Chilean copper industry come to fruition. An investment of $10 billion is underway by the Chilean mining industry to create desalination plants in order to provide additional sources of fresh water to these operations. Antofogasta Minerals is already using seawater in its operations. A $2.6-billion project pumps seawater from the Pacific Ocean along a 145-km (90-mile) pipeline; the seawater is treated prior to use in the mining operations of the Esperanza copper mine in Chile’s Antofagasta region. This practice allows the company to reduce consumption of fresh water that is needed elsewhere in the region.

Chile signed into law legislation that would continue to fund state-owned Codelco during the next five years. Codelco, like many companies, is exploring for deposits at greater depth to support continued production at its established mines and is faced with declining ore grades from its older mines. The ore grades currently being extracted at some mines are not as profitable at the current price of copper. In order to aid the state-owned corporation, the government approved $4 billion in funding in October that would be provided to Codelco from 2014-2018 to cover expenses and manage debt.

According to a World Bank report, the investment climate of Colombia has improved, with greater access to credit made possible by a new secured transactions law and a reduced corporate income tax rate, although legislation to establish a profit tax (CREE) was introduced in 2014. A Colombian legal tribunal ordered 11 gold mining companies to cease operations and restore the land to the indigenous Embera people. Illegal mining activity is still widespread in the region. The governments of Bolivia, Colombia, Ecuador, Guyana, Peru, Suriname and Venezuela have established the Amazon Cooperation Treaty Organization to combat illegal mining activities. From 1999 to 2012, illegal mining in the Amazon region increased 400 percent. The Colombia National Mining Agency reported that 35 percent of the mining titles are for exploration stage projects, 26 percent are for projects under construction and 39 percent are for producing mines.

Legislation was passed by the Senate of the Dominican Republic declaring the region surrounding Glencore Plc’s Falcondo nickel mine a national park. Mining operations and permitting costs could be affected if this legislation is signed into law.

The Guatemalan government approved increases in mining royalties for 2014, which would increase mining royalties from 5 percent to

10 percent.The declining prices of gold and silver

are starting to affect development of projects in Mexico. The weak prices have delayed or suspended at least six precious metals projects with a combined capital budget in excess of $1.5 billion. This is causing some companies to search for or recover higher-grade ores.

Exploration investments in Peru amounted to approximately US$500 million in 2014, down from $760 million in 2013 owing to social conflicts and lack of financing for junior exploration companies. About half of the 120 junior companies operating in Peru in 2012 have exited the country for lack of funding. About 1,000 of the 55,000 mining concessions in Peru are active, according to the Peruvian Ministry of Energy and Mines. Exploration is focused on brownfield projects near producing mines. The Peruvian government approved an economic stimulus package in 2014 that, in part, was intended to reduce the approval time for exploration and environmental impact study certification by as much as 29 months.

The Peruvian government is supporting plans to develop US$14 billion in energy projects over the next 10 years to assist in the development of new copper mines in the country. The Peruvian Energy Ministry reports the expected cost of electricity in Peru in 2020 will be about $0.066 kwh/lb of copper, compared to $0.078 kwh in Argentina, $0.09 kwh in Mexico and $0.12 kwh hour in Chile.

Africa. According to SNL, African exploration budgets decreased to about $1.7 billion in 2014 from about $2.4 billion in 2013, a reduction of 28 percent. Countries with the greatest exploration activity in Africa, based on their exploration budget as reported by SNL for 2014, reported in decreasing order, were Congo (Kinshasa), South Africa, Burkina Faso, Zambia, Tanzania, Ghana, Mali, Angola and Namibia. Based on site data compiled by the USGS, projects containing gold that were actively explored in 2014 accounted for approximately 43 percent of the reported African exploration projects, 17 percent of 2014 projects contained copper, 9 percent of projects contained iron ore, 5 percent of projects contained uranium, 5 percent of projects contained lead or zinc, 5 percent of projects contained platinum-group metals, 5 percent of projects contained diamond, and 11 percent of the projects were targeting other minerals. Exploration was focused primarily in South Africa, Burkina Faso, Congo (Kinshasa), Mauritania, Tanzania, Namibia, Zambia, Ghana and Botswana, in descending order based on the number of sites, but activity also took place in a number of other countries.

An investment of $10 billion is underway by the Chilean mining industry to create desalination plants in order to provide additional sources of fresh water to these operations. Antofogasta Minerals is already using sea water in its operations.


Exploration Review

Based on the number of sites, early-stage projects comprised about 56 percent of the 2014 activity, while producing projects accounted for about 23 percent, feasibility stage projects represented about 11 percent, and developing projects accounted for about 10 percent. Approximately 39 percent of the African exploration budget in 2014 was targeted for late-stage and feasibility activity, 31 percent was for activity adjacent to an existing mine site and 30 percent for grassroots or early-stage activity. Based on SNL data for 2014, junior companies and major companies together accounted for about 80 percent of the exploration budget in Africa. Intermediate companies, small privately held companies and public entities accounted for the remaining 20 percent.

The African mining sector has faced a number of challenges in 2014 that have affected the level of mineral exploration on the continent. In addition to the uncertain global macroeconomic environment and lack of investor capital, African exploration and development was particularly affected by the lack of transportation and energy infrastructure and power shortages, labor strikes in South Africa, and the effects of the outbreak of the Ebola virus disease in West Africa. Other factors that influenced the level of activity included: conflict, corruption and illegal mining; inadequate or confusing regulations and a lack of reliable geologic data. The World Bank announced a plan to initiate a $1-billion program to map African mineral resources beginning in 2014.

The five-month labor strike in South Africa reduced the country’s platinum production by 40 percent and resulted in massive layoffs. It may have also reduced the confidence of investors in mining investment across Africa. The platinum industry in South Africa began a massive restructuring, which has affected the level of exploration and resulted in the closure or temporary suspension of several producing mines.

The Ebola virus outbreak in West Africa appeared to have had only limited short-term effect on mineral exploration and mining in West Africa during 2014. The affected region included Guinea, Liberia, Nigeria and Sierra Leone, and neighboring countries were placed on alert for the disease. The region includes 45 producing mines and ongoing copper, gold and iron ore exploration in the region. Based on SNL data, the 2014 mineral exploration budget allocation for the four countries directly affected by the Ebola outbreak was $84 million, or 49 percent less than the $166 million allocation for 2013. Budgets in surrounding countries (Cote d’Ivoire, Mali and Senegal) also show a 49-percent reduction from

$352 million 2013 to $178 million in 2014. The reported decline in exploration allocation, while likely affected by the ebola situation, can also be attributed to other factors such as the global investment climate.

The government of Burkina Faso was dissolved in 2014 and an interim government established. The transitional government announced plans to review mining contracts signed under the former president, in a manner similar to reviews conducted during the past decade by Congo (Kinshasa) and Guinea. The review in Guinea is ongoing, and delays resulting from the review have affected mineral investment in Guinea.

Project expansions that require additional electricity have been banned in Congo (Kinshasa), and an electricity rationing program has been implemented. The country is experiencing energy shortages that may take several years to resolve. This situation may affect short-term mineral exploration and development activities.

The number of mining licenses issued by the government of Ethiopia has increased from 117 in 2010 to 279 in 2014. Of these, 145 are held by foreign companies, 60 are joint ventures between foreign and local companies, and 74 are held by local companies.

The government of Ghana is in the process of revising the Minerals and Mining Act of 2006 to add regulations to govern illegal mining in the country. Illegal gold operations continue to be an issue in the Ashanti and Eastern regions of the country. A three-month moratorium on new applications for gold exploration is expected to be lifted by the end of 2014, following a review of Ghana’s mining fiscal and regulatory regime.

The parliament of the Cote d’Ivoire (Ivory Coast) adopted a new mining code that is intended to modernize the mining sector of the country. Mining Decree No 2014-397 sets more stringent criteria for the issuance of exploration and mining licenses, establishes a longer license period, reduces the land surface area allowed, outlines criteria for government participation, and establishes tax and customs provisions.

The government of Lesotho passed legislation that tightens requirements for new mining licenses, requiring parties to begin exploration activities within six months of receiving the license.

As part of an ongoing review of existing mining contracts, the government of Mali has canceled 130 mining permits, or about 30 percent of existing permits in the country. The canceled licenses targeted areas where no development has taken place and do not involve mines already in production. Artisanal gold mining is increasing in Mali, as some neighboring countries (Burkina Faso, Ghana and Senegal) have imposed


Exploration Review

restrictions on the sector. The government announced plans to boost funding and policing of the sector. The government also announced agreements with China Railway Engineering Corp. and China Railway Construction Corp. to construct $9.5 billion in rail infrastructure suitable for transporting the country’s bauxite, iron ore and uranium to the Atlantic coast.

The government of Namibia continued its moratorium on planned marine phosphate mining off the coast of Namibia until an environmental impact assessment is completed and it is demonstrated that mining would not harm the country’s fishing industry.

South Africa’s mining industry continued to face a number of challenges. Aging infrastructure, energy shortages, extended labor strikes, regulatory uncertainty and technical constraints resulted in the reduction or curtailment of some exploration and mining in the gold and platinum sectors. Illegal mining activities and possible corruption have been reported. The amended 2002 Mineral and Petroleum Resources Development Act, aimed at streamlining the country’s permitting process, was approved by the National Assembly in March, but it has yet to be signed into law. A five-month labor strike reduced production of platinum in South Africa by 40 percent. Because South Africa is the world’s leading platinum producer, the strike had an impact on global supply and platinum price. Anglo American Platinum, South Africa’s leading producer of platinum-group metals, initiated a 10-year strategy of introducing highly automated, mechanized mining equipment into its mines. Developing South Africa’s Witwatersrand Basin lower-grade, deep gold deposits containing an estimated 36.8 kt (1.3 billion oz) of gold will also require improved technology. In spite of these challenges, a variety of mineral projects continue to be explored and developed, including the Bushveld iron ore, titanium and vanadium projects of Bushveld Minerals Ltd. the Platreef PGM project of Ivanhoe Mines Ltd. and the Waterberg PGM project of Platinum Group Metals Ltd.. Since 2011, the Chinese have invested in 10 South African resource projects for gold, platinum, copper, coal and iron ore.

The government of Zambia has increased royalty rates on openpit mining operations from 6 percent to 20 percent and underground operations from 6 percent to 8 percent, effective Jan. 1, 2015. Barrick Gold Corp. announced plans to suspend its Lumwana copper mine in response to the increased royalties and the government’s decision to retain $600 million in value-added tax refunds from mining companies. The Zambian state power company (ZESCO) has received approval to

increase its bulk power supply agreement tariffs by 25 percent.

The government of Zimbabwe announced plans to reduce the gold royalty from 7 percent to 5 percent, and is considering lowering its platinum royalty from its current level of 10 percent. Power shortages and high borrowing costs have affected the country’s gold sector. Alluvial mining of the Marange diamond field has decreased owing to the depletion of surface reserves and lack of resource capital to explore for resources at depth.

Canada. Statistics as of September, 2014, released by Natural Resources Canada show 2014 planned exploration budgets through the feasibility level at C$2.1 billion (US$1.9 billion), down about 10 percent from an expenditure of C$2.3 billion (US$2.1 billion) for 2013. SNL reported budgeted exploration spending in Canada for 2014 at US$1.5 billion, or about 14 percent of the estimated overall worldwide exploration budget. Canadian government statistics include planned exploration expenditures for a wider variety of minerals than are included in the SNL estimates. It is also important to note that the total of revised 2013 spending intentions for Canada reported by Natural Resources Canada as of March 2014 was 30 percent lower than its March 2013 budget estimate of C$3.3 billion (US$3 billion). In 2014, the exploration and deposit appraisal budget for precious metals (gold and silver) accounted for C$831 million (US$ 753 million); base metals, C$460 million (US$417 million); uranium, C$169 million (US$153 million); iron ore, C$113 million (US$102 million) and diamond, C$102 million (US$92 million) of the C$2.1 billion (US$1.9 billion) exploration total. When the Canadian exploration statistics are reconfigured to make them comparable with SNL statistics, the reported exploration expenditures as of September 2014 by Natural Resources Canada would be C$1.67 billion (US$1.47 billion), very close to the budget estimate reported by SNL.

Company exploration spending for 2014, as reported by the Canadian government as of September 2014, was largest in Ontario (24 percent of the total exploration and deposit appraisal expenditures for Canada), followed by British Columbia (22 percent), Quebec (19 percent), Saskatchewan (11 percent), Nunavut (7 percent), Northwest Territories (5 percent), Newfoundland and Labrador (4 percent), Yukon Territory (4 percent) and other provinces about 4 percent. Canadian provinces with an increase in exploration activity in 2014 from 2013, based on reported budget allocations, were Nova Scotia (with a 59-percent increase), Northwest Territories (32 percent increase) New Brunswick

Although the level of mineral exploration expenditure in Canada has declined about 50 percent in 2014 from a peak in 2011–2012, Canada continues to receive the greatest amount of exploration budget of all individual countries.


(14 percent increase) and Quebec (6 percent increase). The exploration budget in Manitoba decreased 59 percent in 2014 from 2013; for Nunavut, 43 percent; for Alberta, 42 percent; and for Newfoundland and Labrador, 24 percent.

Senior exploration companies accounted for about 63 percent of Canadian exploration expenditures in 2014, compared to about 59 percent in 2013. In terms of mineral commodities sought country-wide, precious metals received the largest exploration expenditure (39 percent), followed by base metals (22 percent), uranium (8 percent), iron ore (5 percent) and diamond (5 percent) in 2013. Other mineral commodities compose the remaining 21 percent.

Canadian provinces or territories with the largest exploration activity, in descending order by number of sites in 2014 as compiled by the USGS, were Quebec, Ontario, British Columbia, Saskatchewan, Newfoundland/Labrador, Yukon Territory, Northwest Territories, Nunavut, Manitoba and New Brunswick. Based on the site data, 53 percent of the Canadian exploration sites targeted precious metals in 2014, 28 percent base metals, 8 percent uranium, 4 percent iron ore, 3 percent diamond, 2 percent graphite and 2 percent other mineral commodities. Approximately 77 percent of all reported exploration sites were considered early-stage sites.

Although the level of mineral exploration expenditure in Canada has declined about 50 percent in 2014 from a peak in 2011-2012, Canada continues to receive the greatest amount of exploration budget of all individual countries. In recent years, interest has been affected by the global economy, a complex regulatory environment, an increasing skills shortage and a lack of critical infrastructure.

Aboriginal (First Nations) consultation was considered a significant issue by the Canadian government, nongovernment organizations and the mining industry. As many as 600 mineral resource projects are under consideration for development over the next 10 years in Canada, and many of them are either in or within a 100-km (62-mile) radius of aboriginal communities. According to the Canadian government, development within close proximity of aboriginal lands cannot take place without engagement of the aboriginal community. Each province has established, or is in the process of establishing, procedures for consulting and negotiating with aboriginal groups, but differences in these procedures have led to confusion and project development delays. A 2014 Supreme Court of Canada ruling granting six First Nations title to a large piece of land outside their reserves is likely to have national implications for mineral development.

At the provincial level, the British Columbia government announced regulatory changes designed to make exploration and mining more efficient in the province and improve the environmental assessment and permitting process. The provincial government also extended the mining exploration tax credit for 2014, and the 2015 budget includes provisions for a further extension of the tax credit to the end of 2015 and to extend the New Mine Allowance to 2020.

In Ontario, the Northern Ontario Heritage Fund Corp. provides funds for mining research and investment. The organization has invested C$853 million in 6,200 projects across northern Ontario since 2003. The Ontario government established the Ring of Fire Infrastructure Development Corp. to allow collaboration between First Nations and the public and private sectors to create partnerships and facilitate investment in strategic transportation infrastructure.

Since 2011, mineral exploration in Quebec has declined about 52 percent. In 2013, the government of Quebec placed a moratorium on the issuance of exploration and mining permits for uranium in the province until an environmental impact study is performed. It also passed Bill 70, An Act to amend the Mining Act (Quebec), which adds certain requirements to the application process related to increasing local and First Nations involvement, consideration of local ore processing, and further defines reporting and consultation requirements (Gervais, 2014) and Bill 11, which modifies and clarifies the responsibility of the Société du Plan Nord (SPN) in the development of northern Quebec.

Australia. Exploration budget allocations reported by SNL for Australia showed a decrease to about US$1.3 billion in calendar year 2014 from US$1.9 billion in calendar year 2013. The Australian Bureau of Statistics reports expected mineral exploration expenditures (including coal and excluding petroleum) for their fiscal year from July 2013 through June 2014 of about A$2 billion (US$2.2 billion), about a 20-percent decrease from the actual Australian expenditure for fiscal year 2012-2013 of A$2.5 billion (US$2.6 billion). The Western Australia Department of Mines and Petroleum reports that the number of prospecting licenses for minerals and coal in Western Australia decreased about 3.4 percent from the 2012-2013 fiscal year to the 2013-2014 fiscal year, and the number of exploration licenses decreased 12 percent for the same period. The Australian statistics include expenditures for coal, industrial minerals and mineral sands that are not included in the SNL statistics.

The estimated expenditures for iron ore

Exploration Review


exploration in Australia accounted for 40 percent of the total Australian expenditure for metals and minerals for fiscal year 2013-2014 (excluding coal and petroleum), compared to 44 percent for 2012-2013, based on data reported by the Australian Bureau of Statistics as of Jan. 12, 2015. Gold exploration accounted for about 26 percent of the total nonfuel Australian expenditure for metals and minerals for 2013-2014 and 26 percent in 2012-2013. In current dollar terms, gold exploration in Australia decreased about 37 percent in 2014 from the corresponding period in 2013. Uranium and coal are included in the Australian Bureau of Statistics data, but coal statistics have been removed from the statistics reported in this summary. Base metals accounted for 19 percent of the total nonfuel Australian expenditure in 2013-2014, compared to 22 percent in 2012-2013. The estimated expenditure for base metals exploration in Australia decreased 43 percent in 2013-2014 from 2012-2013. Uranium accounted for about 2.6 percent of the total nonfuel Australian expenditure in 2013-2014, compared to 3 percent in 2012-2013. Heavy-mineral sands accounted for about 3 percent in 2013-2014 from about 1.5 percent in 2012-2013. Other minerals (including construction materials, tin and tungsten) accounted for about 9.4 percent in 2013-2014 and 6.4 percent in 2012-2013.

Western Australia accounted for 57 percent of the Australian mineral exploration expenditure (excluding petroleum) in 2013-2014; Queensland, about 22 percent; New South Wales, about 7 percent; Northern Territory and South Australia, about 6 percent each; and Victoria and Tasmania, about 1 percent each.

Western Australia accounted for about 52 percent of the active Australian sites compiled by the USGS. Queensland accounted for about 14 percent; Northern Territory, about 10 percent; New South Wales and South Australia, about 9 percent each; and Tasmania and Victoria, about 3 percent each.

About 6.4 million m (4,000 miles) were drilled at mineral prospects in Australia in 2013-2014, compared to 8.4 million m (5,200 miles) in 2012-2013. Of this drilling, approximately 74 percent was performed on exploration at continuing projects and 26 percent was focused on exploration of newly discovered prospects. The early-stage (greenfield) project share has decreased from about 45 percent of the Australian exploration budget in 2003 to a low of 32 percent in 2013, rebounding slightly to about 36 percent in 2014. There has been a noticeable shift in activity from greenfield exploration to brownfield (areas previously explored or mined) exploration.

Junior mining companies, which conduct

the majority of early-stage exploration activity, accounted for more than 50 percent of the exploration budget in Australia during the period of 2005-2011. Since the global economic downturn in 2008-2009, however, junior mining companies have found it more difficult to secure financing, so have had to focus exploration expenditures on fewer projects or reduce the exploration budgets at individual projects. Major companies have effectively increased their share of exploration in Australia.

Data released by the Australia Bureau of Resources and Energy Economics (BREE) show that investment in the country’s mining industry for early-stage and feasibility-stage projects has declined since mid-2012. The number of uncommitted projects (including coal and oil and gas) declined by 22 percent from October 2013 to October 2014. As of October 2014, there were 22 mineral projects reported at the committed stage, as the Australian mining sector moves from the investment phase to the production phase. This transition is estimated to reduce labor in the sector by 20 percent by 2020.

During 2014, the Australian Senate repealed the carbon tax imposed on large industrial users in 2012 and repealed the Mineral Resource Rent Tax imposed in 2013. In an effort to stimulate the country’s declining mineral exploration industry, the government introduced legislation that would provide A$100 million (US$83 million) in funding to exploration companies through tax incentives over a three-year period. The total value of the tax stimulus for 2014 was estimated at A$35 million (US$29 million). The government agreed upon a free trade agreement with China, which would reduce limitations on Chinese investment in Australia and provide a duty-free status for most Australian exports.

The government of New South Wales has selected six companies to apply for uranium exploration licenses in the state. Although a uranium mining ban remains in place, this action represents the first step to permit uranium exploration and mining since legislation authorizing uranium exploration was passed in 2012.

United States. The U.S. nonfuel mineral exploration budget decreased by about 27 percent to less than $800 million in 2014 from $1 billion in 2013, according to SNL. The U.S. percentage of the world exploration budget was 7 percent in 2014. Gold was the principal commodity targeted for exploration in 2014, followed by base metals (primarily copper) and uranium. About 10 percent of the 2014 exploration budget in the United States targeted other minerals. Major companies

accounted for about half of the total U.S. budget. Less than 30 percent of the U.S. exploration budget was for early-stage exploration. SNL data suggest that exploration drilling in the United States increased about 31 percent in 2014 from the level in 2013, based on the number of holes drilled.

In 2014, data on 226 U.S. active exploration projects were collected and reviewed by the USGS; 37 percent were located in Nevada, 11 percent in Arizona, 10 percent in Alaska, 7 percent in Utah, 5 percent each in Idaho and New Mexico, 4 percent each in California and Florida, and 3 percent each in California, Colorado and Wyoming. The remaining 8 percent took place in Alabama, Arkansas, Michigan, Minnesota, Montana, Nebraska, Oregon, South Carolina, South Dakota, Texas and Washington. Most of these sites had prior exploration activity, suggesting that economic conditions were such that exploration companies were continuing prior exploration activity, or re-evaluating sites based on technological advancements that would improve recovery or their proximity or geologic similarity to other recent discoveries.

Exploration for precious metals represented about 84 percent of projected mineral exploration activity based on 2014 site data compiled by the USGS. The principal exploration objectives in Nevada continued to be gold and silver based on USGS site data, although some exploration for copper, lead, lithium, molybdenum, potash, tungsten and zinc took place in Nevada during 2014. Based on U.S. Bureau of Land Management statistics, there were about 175,000 active claims in Nevada in 2014, down from about 199,000 claims in 2013.

There was a reduced amount of exploration activity in Alaska during 2014. Preliminary data suggest exploration spending in Alaska in 2014 to be between $80 million and $100 million, or about half of the reported expenditure of $176 million in 2013 and about 22 percent of the peak expenditure of $365 million in 2011. Based on a 2014 report released by the Alaska Department of Natural Resources, exploration expenditures (excluding development projects) spent in 2013 in Alaska decreased about 5 percent from the 2012 level. About 42 percent of the total estimated expenditure for 2013 was spent in southwestern Alaska, 27 percent in the eastern interior, 13 percent in the northern region, 9 percent in the southeastern region, 8 percent in the western region and 1 percent in the south-central region. About 59 percent of this expenditure was for polymetallic deposits of base and precious metals, 35 percent for precious metals, 5 percent for base metals, and the remaining 1 percent for coal, industrial minerals, peat, and other minerals. In

2013, approximately 6,900 federal and 42,000 state mining claims were active. Data for 2014 were unavailable.

Mineral exploration in Alaska in 2014 was affected by lower commodity prices, reduced availability of capital, and actual and perceived changing regulatory climate for the Alaskan mining sector. In February 2014, the U.S. Environmental Protection Agency (EPA) announced plans to initiate a process to protect the Bristol Bay fisheries from future mining of the Pebble copper-gold project. Although the EPA subsequently halted implementation of the process until at least January 2015, the mining industry reacted to this announcement by curtailing a significant amount of its planned exploration and development expenditure in Alaska in 2014 until the regulatory environment could be clarified. Exploration on the polymetallic Pebble project had accounted for more than 86 percent of the $77 million spent on copper porphyry exploration in Alaska in 2013, based on data from the Alaska Department of Natural Resources.

The U.S. Senate included legislation authorizing a transfer of landholdings in Arizona as part of its authorization of the 2015 budget for the U.S. Department of Defense. The legislation allows Rio Tinto, the operator of the Resolution copper project, to acquire 971 ha (2,400 acres) in the Tonto National Forest in exchange for 2,000 ha (5,000 acres) of company held parcels across the state, making it possible for the mine to be developed. A similar land swap was approved in December that transferred 4,280 ha (10,400 acres) of federal land to the city of Yerlington, NV, a precondition for the development of Nevada Copper Corp.’s Pumpkin Hollow copper project. A federal court ruled that the 20-year ban on uranium mining near the Grand Canyon will remain in place.

Pacific Region. Based on SNL data, the 2014 exploration budget allocation for the Pacific region and Southeast Asia (excluding Australia) was about $600 million, down 38 percent from the 2013 level of almost $1 billion. Indonesia, Papua New Guinea and the Philippines together accounted for about 82 percent of the total mineral exploration budget for the region when Australia is excluded. Much of the sustained interest in this region can be attributed to the continued interest by Chinese and South Korean companies to expand sources of supply for gold, base metals and REE and by Japanese companies to develop regional copper and nickel deposits to supply Japan’s smelting industry. Based on the data on active exploration sites compiled by the USGS, the three countries included in this region

with the largest number of exploration sites were Indonesia, the Philippines and Papua New Guinea, together accounting for 67 percent of the active exploration sites in the region in 2014. Other countries with active exploration in 2014 include Burma (Myanmar), Cambodia, Fiji, the Republic of Korea, Laos, Malaysia, New Caledonia, New Zealand, the Solomon Islands, Thailand and Vietnam. Base and precious metals accounted for about 90 percent of all exploration activity in the Pacific region, with minor exploration activity for iron ore and other minerals in 2014. About 47 percent of the sites in this region were conducting early-stage exploration, 23 percent were exploring for minerals adjacent to producing mines, 20 percent were undergoing feasibility studies and 10 percent were in development.

The Constitutional Court in Indonesia upheld the country’s ban on the export of unprocessed ore that came into effect in January 2014. While nickel ore and bauxite exports from Indonesia have been curtailed, nickel exports from the Philippines and Vietnam have increased to meet continued demand from China. China has begun sourcing bauxite from stockpiles and other countries in the region. Consequently, interest in exploration for nickel and bauxite increased in 2014 from countries in the region.

Revised mining regulations in New Zealand and the establishment of a two-tiered minerals permitting system have increased interest in mineral exploration in the country. Approximately 1,000 prospecting, exploration and mining permits are in effect in the country, and 357 permits were approved in 2013.

Legislation was passed in 2014 transferring control over mining activities in the autonomous region of Bougainville from the Papua New Guinea government to the local legislature. The legislation means that the agreement between Bougainville Copper Ltd. and the government is no longer in effect, and a new agreement must be negotiated before copper production can continue.

Rest of World. Exploration budget allocations for the Rest of the World (including China, India, Mongolia, Southeast Asia, the countries of the Commonwealth of Independent States, Europe and the Middle East, as defined in footnote 1) decreased by about 13 percent in the 2014 SNL survey to about $2 billion from the $2.4 billion budget reported in its 2013 survey. Russia and China accounted for about 56 percent of the region’s exploration budget based on SNL data. Based on the amount budgeted for exploration, the countries with the greatest exploration activity from this diverse region in 2014 are China,

Russia, Kazakhstan, Turkey, Sweden, India, Finland, Saudi Arabia and Mongolia. Together, these countries account for about 81 percent of the regional exploration budget.

Data for 2013 mineral exploration investment reported by the Chinese Ministry of Land and Resources is higher than the budget data reported for China by SNL for 2013. A 2013 expenditure of 46 billion yuan ($7.5 billion dollars) is reported for non-oil-and-gas minerals exploration, but this expenditure likely includes expenditures for a wider variety of mineral commodities (ferrous metals, industrial minerals) than the SNL estimate. In addition, it is likely that this estimate includes exploration expenses incurred by public and quasi-public entities not covered in the SNL survey. Data for 2014 were not reported.

In terms of the number of exploration sites, Russia, China, Turkey, India, Sweden, Spain, Kazakhstan, Mongolia and Finland were the most active countries. On the basis of exploration site data collected by the USGS, Russia accounted for about 18 percent of active exploration sites in this composite region; China, about 13 percent; Turkey, about 6 percent; India, Kazakhstan, Mongolia, Spain and Sweden, about 5 percent each; and Finland, about 4 percent. The remaining 34 percent took place in 31 other countries in Asia, the Commonwealth of Independent States, Europe and the Middle East.

Based on the number of exploration sites compiled by the USGS, exploration activity in Asia in 2014 primarily focused on base metals (50 percent of all Asian sites), precious metals (38 percent), iron ore (9 percent) and other minerals (3 percent). Exploration activity in the Commonwealth of Independent States focused on precious metals (67 percent), base metals (28 percent), iron ore (3 percent) and other minerals (2 percent). European mineral exploration primarily focused on base metals (37 percent), precious metals (32 percent), tungsten (8 percent), iron ore (6 percent) and other minerals (17 percent). Middle Eastern exploration (including Turkey) primarily focused on copper (54 percent), gold (27 percent), zinc (11 percent) and other minerals (8 percent).

The USGS released a series of maps in 2014 outlining the mineral potential of Afghanistan using hyperspectral imaging techniques. In July, Afghanistan passed its first mining law and the government has awarded two mining contracts, one to a Chinese company for copper exploration and the other to an Indian company for iron ore.

The Chinese government is continuing to encourage domestic companies to invest globally. Prior to 2014, Chinese companies had to seek approval from both the Ministry of Commerce

Exploration Review


and the National Development and Reform Commission (NDRC) before they could proceed with investments in foreign countries. Under new rules issued by the Ministry of Commerce in 2014, registration requirements by domestic entities seeking overseas investment have been modified, according to the State Administration of Foreign Exchange. Chinese state-owned mining companies, private companies and investment groups are increasingly investing in overseas mining projects in two ways; some companies choose to acquire mining projects and apply for exploration and mining licenses by themselves, while other companies prefer to undertake mergers and acquisitions in more developed markets such as Australia and Canada.

The Chinese rare earths industry continued to undergo change in 2014. The World Trade Organization (WTO) found China’s export restraints on rare earths, tungsten and molybdenum to be inconsistent with China’s WTO obligations. China has increased its efforts to restrict illegal mining and export of rare earths. The Inner Mongolia Baotou Iron and Steel Rare Earth Group continued to consolidate the industry by announcing plans to merge with five other firms to establish the China North Rare Earth Group. In December 2014, the Ministry of Commerce announced the termination of rare earth export quotas.

The Estonian government approved legislation increasing the tax rate on mineral resource extraction by 3 percent and 6 percent annually from 2016 to 2025. The 3 percent rate applies to the shale oil industry and the 6 percent rate applies to peat, clay, sand and dolomite.

The government of India approved plans to increase royalty rates on 23 of 51 minerals. The royalty rate for iron ore and chromite was increased from 10 percent to 15 percent ad valorem, bauxite ore was increased from 0.5 to 0.6 percent and the rate for manganese ore was increased from 4.2 percent to 5 percent. The ministry planned to establish a National Mineral Exploration Fund using funds collected from the royalties.

With the implementation of the raw material export ban from Indonesia in 2014, Chinese companies have been investing in downstream processing facilities in Indonesia. In 2014, Shanghai-based ore trader Pan Pacific Group Co. Ltd. and Chinese steel producer Delong Holdings Ltd. announced plans to jointly construct a nickel processing plant. A second nickel processing facility is under construction by China Hanking Holdings Ltd.

The development of phase two of the large

Oyu Tolgoi copper project is progressing, as Rio Tinto secured an agreement with the Mongolian government for the construction of a power generation plant to supply the project. Currently, the project is sourcing its power from China’s state-owned Inner Mongolia Power Corp.. The government also announced the intent to open up an additional 10.1 million ha (39,000 sq miles) of territory for mining exploration.

Kazakhstan, Russia and Uzbekistan have increased investment in uranium exploration and development in recent years, leading to a growth in uranium production in these countries. Large uranium deposits in Russia are located in Yakutia and the Trans-Baikal region, and several new mines in North Kazakhstan and Chu-Sarysu region are being considered for development in Kazakhstan. Resource investments in the Russian Far East are reported to increase from $715 million in 2014 to $1.9 billion in 2015 through a number of public-private partnerships in the mining sector. A joint agreement to explore for metals such as beryllium, cesium, lithium, niobium, rubidium and tantalum in the Juzkuduk and Tamdiykuduk-Tulyantash regions of Uzbekistan has been agreed upon between the Japan Oil, Gas, and Metals National Corp. (JOGMEC) and the Uzbek State Committee on Geology and Mineral Resources.

The United Kingdom passed legislation in 2014 in line with the 2013 EU Accounting and Transparency Directives that require oil and gas and mining companies to publicly disclose payments made to governments for the extraction of natural resources. Once the EU Directives and similar ones in the United States are enacted, these laws would cover 65 percent of extractive companies by value worldwide. n

Exploration Review


In 2014, the estimated value of total mine production of nonfuel minerals in the United

States increased. The quantity of production increased for most mineral commodities mined in the United States, as did prices. Notable exceptions were the declines in prices for most precious metals. Minerals remained fundamental to the U.S. economy, contributing to the real gross domestic product (GDP) at several levels, including mining, processing and manufacturing finished products. Following the reduction in construction activity associated with the 2008–2009 recession that continued through 2011, the construction industry continued to expand in 2014, with increased production and consumption of cement, construction sand and gravel, crushed stone and gypsum, mineral commodities that are used almost exclusively in construction. Other segments of the nonfuel minerals industries increased as well. Trends in other sectors of the domestic economy were similar to those for industrial mineral production (Table 1).

Discussion of mine production is frequently segmented according to the type of materials produced within the broad categories of metals and industrial minerals. Industrial minerals can be further subdivided as construction aggregates and other industrial minerals. The materials with the highest unit values, usually metals, tend to have very low production rates compared with those of many low-valued materials, such as crushed stone or construction sand and gravel. Therefore, for discussion and analysis of the performance of the minerals industry in general, the value of production is used rather than tonnage produced. Although the value of metals and industrial minerals mined in the United States are similar, if tonnages are compared, construction aggregates dominate, dwarfing the production of all other minerals combined.

Mineral industry performance The estimated value of nonfuel mineral

raw materials, including metals and industrial minerals, produced at mines in the United States in 2014 was $77.6 billion, a 3.5-percent increase from $75 billion in 2013 (Table 2). Net exports of mineral raw materials and old scrap were $15 billion (Fig. 2). Domestic raw materials, along with domestically recycled materials, were used to process mineral materials worth $697 billion. These mineral materials, including aluminum, brick, copper, fertilizers and steel, and net imports of processed materials (worth about $41 billion)

were, in turn, consumed by downstream industries with a value added estimated to be $2,530 billion in 2014.

In the United States in 2014, mine production of each of 14 mineral commodities was worth more than $1 billion. These were, in decreasing order of value, crushed stone, copper, gold, cement, construction sand and gravel, iron ore (shipped), industrial sand and gravel, molybdenum concentrates, phosphate rock, lime, salt, zinc, soda ash and clays (all types).

The United States continued to rely on foreign sources for many raw and processed mineral materials. In 2014, the supply for more than one-half of U.S. apparent consumption of 43 mineral commodities came from imports, and the United States was 100 percent import reliant for 19 of those mineral commodities (Fig. 3). U.S. import reliance has increased significantly since 1973, the earliest year for which this information was reported. At that time, the United States was 100 percent import reliant for six mineral commodities, and more than 50 percent import reliant for another 20 mineral commodities. In 2014, the United States was a net exporter of 17 mineral commodities, meaning that more of those domestically produced mineral commodities were exported than imported. That figure has remained relatively stable since 1973, when the U.S. was a net exporter of 20 mineral commodities.

In 2014, 12 states each produced more than $2 billion worth of nonfuel mineral commodities.

These states were, in descending order of value, Arizona, Nevada, Minnesota, Texas, Utah, California, Alaska, Florida, Missouri, Michigan, Wyoming and Colorado. The mineral production of these states accounted for 62 percent of the U.S. total output value (Table 3 and Fig. 4).

The Defense Logistics Agency (DLA) Strategic Materials is responsible for providing safe, secure and environmentally sound stewardship for strategic and critical materials in the U.S. National Defense Stockpile (NDS). DLA Strategic Materials stores 27 commodities at nine locations in the United States. In fiscal year 2014, DLA Strategic Materials sold $68 million of excess mineral materials from the NDS. At the end of the fiscal year, mineral materials valued at $1.5 billion remained in the NDS. Of the remaining material, some was being held in reserve, some was offered for sale, and sales of some of the materials were suspended. Under the authority of the Defense Production Act of 1950, the U.S. Geological Survey (USGS) advises the DLA on acquisition

and disposal of NDS mineral materials.

MetalsThe estimated value of U.S. metal mine

production in 2014 was $31.5 billion, slightly less than that of 2013. Principal contributors to the total value of metal mine production in 2014 were copper (32 percent), gold (27 percent), iron ore (16 percent), molybdenum (10 percent), zinc (6 percent), lead (3 percent) and silver (2 percent). The remaining 4 percent of metal mine production value was from seven other metals, each accounting for less than 1 percent of the total. The average prices for most domestically mined metals decreased in 2014.

Precious metals. Preliminary data indicate that domestic gold mine production in 2014 was 8 percent less than that of 2013. The decrease in domestic mine production was attributed to lower ore grades at the two leading producers in Nevada. These decreases were partly offset by

If measured by tonnage, construction aggregates dwarf the performance of the other sectors.production from one mine

in Utah, which continued to recover following a massive landslide in April 2013. Worldwide gold production was 2 percent more than that in 2013 owing to increases in production from Australia, Canada, China, the Dominican Republic and Russia, which more than offset production decreases in Peru, Tanzania, South Africa and the United States. Gold production in China continued to increase, and the country remained the leading gold-producing nation, followed by Australia, Russia, the United States, Peru and Canada.

The estimated gold price in 2014 was 10 percent lower than the price in 2013 and was down by 24 percent from the record-high annual price in 2012. Industry experts attributed the decline in the average price of gold to the lack of confidence in gold as an investment.

Preliminary data indicate that total U.S. silver production in 2014 was 12 percent higher than 2013 production. World silver mine production was essentially unchanged at 26.1 kt (28,800 st), principally with increased production from mines in Australia, Bolivia, China, Peru and the United States offset by declines in Mexico, the leading producing country. The average silver price was about 20 percent lower in 2014 than in 2013. The overall decline in silver prices corresponded to a small drop in global industrial consumption owing to slower economic growth, particularly in the eurozone, and to substitution.

Stillwater Mining Co.’s two mines in Montana were the only primary platinum-group metals (PGMs) mines in the United States, but small quantities of PGMs also were recovered as byproducts of copper refining. Prices of platinum fluctuated during the year and were not markedly affected by labor strikes in South Africa because producers processed PGMs from stocks. In contrast, prices of palladium steadily increased throughout the year, reaching $28.93/g ($900/oz) in August for the first time since 2001. Palladium prices were supported by the political crisis in Ukraine, which led to concerns that economic sanctions might be enforced against Russia, the world’s leading producer of palladium, and that supply disruptions might occur. Prices for rhodium fluctuated in the first half of the year and spiked in August, when prices were briefly higher

than those for platinum for the first time since December 2011, owing to increased investor and industrial demand. Prices for iridium increased throughout the year but the average annual prices for both iridium and ruthenium were below those for 2013.

Ferrous metals. In 2014, mines in Michigan and Minnesota shipped 93 percent of the usable iron ore produced in the United States. Twelve iron ore mines (nine openpits and three reclamation operations), nine concentration plants, 10 pelletizing plants, two direct-reduced iron plants and one iron nugget plant operated during the year. Almost all ore was concentrated before shipment. The United States was estimated to have produced and consumed 2 percent of the world’s iron ore output.

Following the completion of several infrastructure improvement and capacity expansion projects in Western Australia, regional shipments increased to record levels. Increased production in Australia and lower than expected consumption in China, however, created a global oversupply. As a result, spot market prices plummeted, and mine closures in Australia, Canada and China were attributed to low prices.

Nonferrous metals. In 2014, U.S. primary aluminum production decreased by 12 percent from 2013. One of the smelters that produced primary aluminum during 2014 was permanently shut down in May. A new smelter was being built at the same site as required by the terms of a power contract. However, construction was suspended as the result of unfavorable market conditions. Another smelter in Hannibal, OH, that was temporarily idled in 2013 was closed permanently because of high power costs. In September, a smelter in Evansville, IN, temporarily shut down a potline after an electrical fire. By November 2014, domestic smelters were operating at about

71 percent of capacity. World primary aluminum production increased by about 3 percent in 2014 compared with production in 2013. New capacity built in recent years in China, where production increased by 5 percent, accounted for most of the increased production.

U.S. mine production of copper increased by about 10 percent in 2014, mainly owing to significant increases in production in Arizona, New Mexico and Utah. Copper production at the Bingham Canyon Mine in Utah increased following recovery from a pit-wall failure in 2013, and in May, an expansion of copper in concentrate capacity was completed at the Morenci Mine in Arizona. Total U.S. refined production increased by about 8 percent owing to across-the-board production increases at electrolytic refineries. In 2015, domestic mine and refined production of copper were expected to increase moderately, and global refined-copper output was expected to exceed demand owing to lower demand growth in China and a 4.3 percent growth in global refined production.

Domestic lead mine production in 2014 increased by 4 percent from that in 2013. Six lead mines in Missouri, plus four mines in Alaska and Idaho that produced lead as a coproduct, accounted for all domestic mine production. The Herculaneum, MO, lead smelter, the only domestic primary lead smelter, closed at yearend 2013, per an agreement with the U.S. Environmental Protection Agency. In 2014, the

plant processed a small amount of residual lead during demolition of the site. Following closure, the owner exported concentrates produced at its six mines in Missouri. Global mine production of lead was estimated to be about 5 Mt (5.5 million st) in 2014, with production increases in Australia, China and the United States.

Domestic zinc mine production increased by 5 percent in 2014 from that of 2013 owing to increased production at the Red Dog Mine in Alaska. Mill throughput at the mine rose significantly as a result of processing softer ores from the Aqqaluk deposit. The Pend Oreille Mine in Washington reopened in 2014 and began shipping concentrates by yearend. Zinc metal production decreased by 20 percent owing to a decline in secondary production; a zinc-recycling company closed its smelter in Pennsylvania coincident with the startup of its new recycling facility in North Carolina in the second quarter. Global zinc mine production in 2014 was 12 Mt (13.3 million st), essentially unchanged from 2013.

Industrial mineralsThe value of output of industrial minerals

and materials from mines in the United States was $46.1 billion, 7.5 percent higher than it was in 2013. This accounted for 59 percent of the value of all nonfuel raw mineral materials produced from domestic operations in 2014. More than 6,500 companies contributed to this value, producing from more than 12,000 mines,

Figure 2The role of nonfuel minerals in the U.S. economy in 2014. Values estimated by the U.S. Geological Survey based on U.S. Department of Commerce data. Major consuming industries of processed mineral materials are construction, durable goods, and some nondurable goods manufacturing. quarries and processing

facilities. Byproducts from other industries used as raw materials in industrial mineral applications contributed an additional $5.9 billion in value. Overall, the quantity of production of industrial minerals increased by 3 percent owing to an increase in construction markets in 2014.

Agricultural minerals. Industrial mineral use in agriculture is dominated by nitrogen, phosphate rock, potash and sulfur, the first three of which are used in fertilizers to provide nutrients for plants. Sulfur (as sulfuric acid) is essential for processing phosphate rock, but also plays a role in plant nutrition. Phosphate rock production in the United States decreased by 13 percent in terms of quantity produced, and potash declined by 11 percent in 2014 compared with 2013. Nitrogen and sulfur were not mined domestically, but the United States is a significant producer of both materials. Nitrogen is commercially recovered from air as ammonia, which is produced by combining nitrogen in the atmosphere with hydrogen from natural gas. Elemental sulfur is recovered as a byproduct of natural gas processing and petroleum refining, and byproduct sulfuric acid is recovered at nonferrous metal smelters. Nitrogen production was about the same in 2014 as it was in 2013, and sulfur production increased by 6 percent. The value of production of industrial minerals used in agriculture, including peat and greensand, decreased slightly to $9 billion in 2014.

U.S. phosphate rock production was estimated to have been lower in 2014 compared with that of 2013, owing to producers drawing from higher than average phosphate rock inventories and the closure of the last phosphate rock mine in Polk County, FL. The leading U.S. phosphate rock producer completed its acquisition of the phosphate assets of another producer in central Florida, adding a fertilizer plant, mine and processing facility to its assets. Domestic consumption decreased because of lower phosphoric acid and fertilizer production.

World phosphate rock production was estimated to be slightly lower in 2014 because of lower output, especially from China. Expansion of existing mines in Morocco and development of a new mine in Saudi Arabia, as well as smaller expansion projects at existing mines in Jordan, Kazakhstan, Peru, Russia and Tunisia, are expected to increase world phosphate rock production capacity from 230 Mt (253 million st) in 2014 to 260 Mt (287 million st) in 2018.

Potash production in the United States decreased because of the closure of a mine in Michigan in late 2013 and lower production in New Mexico. In New Mexico, a new solar solution mine began production in 2014 with the expectation of reaching full capacity in 2015. Another company received approval to begin construction of a new underground potash mine in southeastern New Mexico, which planned to begin production in 2017 or 2018. Development of new mines and expansions of existing facilities continued in Argentina, Brazil, Canada, Congo (Brazzaville), Eritrea, Ethiopia, Russia, Turkmenistan, the United Kingdom and Uzbekistan. Many projects, however, were delayed because of existing excess production capacity and lower prices.

Because natural gas is the dominant cost input necessary for nitrogen production, a long period of stable and low natural gas prices in the United States has made it economical for companies to upgrade existing plants and plan for the construction of new nitrogen plants. During the next four years, it is expected that about 4 Mt/a (4.4 million stpy) of production capacity will be added in the United States. Global ammonia capacity is expected to increase by 16 percent during the next four years. Additions to capacity are expected in Asia, Africa, the Middle East and Latin America. The largest growth is expected in China and Indonesia.

Total U.S. sulfur production and shipments increased by about 6 percent compared with 2013. Domestically, petroleum refinery sulfur production is expected to continue to increase as a result of processing more Canadian bituminous crude. Sulfur from natural gas processing is expected to remain stable, and byproduct sulfuric acid is expected to remain stable, unless one or more of the remaining nonferrous smelters close. World sulfur production increased by about 3 percent and is likely to steadily increase for the foreseeable future. Significantly increased production is expected from sulfur recovery at liquefied natural gas operations in the Middle East and expanded oil sands operations in Canada, unless a downturn in the world economy limits investments in those areas.

Chemical minerals. The quantities of domestically produced minerals that are used extensively by the chemical industry ranged from 44.1 Mt (48.6 million st) of salt to a group of other minerals that totaled less than 2 kt (2,200 st). In addition to salt, major chemical minerals used included lime, 19 Mt (21 million st); soda ash, 11.6 Mt (12.8 million st) and sulfur for chemical uses, 3.2 Mt (3.5 million st). The combined value for all minerals used as raw materials for chemical products, including those for which data were withheld but excluding sulfur, which is not mined, was about $7.3 billion in 2014, slightly higher than in 2013. Lime and salt were valued at $2.2 billion each, and soda ash, $1.7 billion. Other minerals included in this end use were bromine, boron, iodine, lithium carbonate, magnesite, magnesium compounds and olivine, but specific commodity information was withheld to avoid disclosing company proprietary data.

Many factors affect production and consumption for these mineral materials. In general, demand will be affected by the state of the U.S. economy, which was expanding during 2014. Because several of these commodities have significant export components, their domestic production also reflects the economic conditions in other regions of the

world. Economic downturns worldwide can have a negative impact on these export-dependent commodities.

Construction minerals and materials. Almost 2.3 Gt (2.5 billion st) of industrial minerals and materials was mined and processed in the United States during 2014 for construction applications, which were dominated by cement, construction sand and gravel, and crushed stone. The value of these materials was an estimated $29 billion, almost two-thirds of the value of all industrial mineral mine production. The construction industry led the demand for all mineral materials.

Construction aggregates (crushed stone, construction sand and gravel, and iron and steel slag) were mined or processed in all 50 states and were valued at $20 billion. More than three-quarters of the aggregates sold was used in road construction. Of the 2.2 Gt (2.4 billion st) produced (7 percent more than in 2013), crushed stone accounted for about 58 percent of the tonnage of aggregates used in construction, sand and gravel accounted for about 42 percent, and slag less than 1 percent. Aggregates production is expected to increase again in 2015 compared with 2014. Potential increases in construction aggregates demand will be influenced by activity in the public and private construction sectors, especially for road construction.

Cement production accounted for 27 percent of the value of construction materials in 2014. The value of production of cement of all types increased by 15 percent in 2014 compared with 2013, and the quantity increased by 7 percent.

About 25 Mt (27.6 million st) of all varieties of clays, valued at about $1.55 billion, was mined in the United States. Although not all clays are used in construction, common clay, the type mostly used in the construction industry, accounted for 44 percent of the tonnage but only 10 percent of the value of all clays. It was used mainly for brick (39 percent), cement (31 percent) and lightweight aggregates (23 percent). Kaolin accounted for 5.8 Mt (6.4 million st) or 23 percent of the total clay tonnage and 64 percent of the value. Paper coatings accounted for 47 percent of kaolin usage.

Other industrial minerals. The United States produced several other industrial minerals that do not fall in the three major categories discussed previously, including barite, diatomite, feldspar, helium, kyanite, and industrial sand and gravel. Some of the end uses for these industrial minerals are abrasives, absorbents, catalysts, ceramics and glass, coatings, cryogenics, fillers and extenders, filtering agents, grinding and polishing materials, optoelectronics, pigments and refractories. n


Record number of exhibitors at 2015SME Annual Conference & Expoby Georgene Renner and William Gleason, Senior Editors, and Chee Theng, Technical Editor

With more than 900 booth spaces sold and 630 exhibiting companies displaying their wares,

there was something for all 7,804 attendees on the exhibit floor of the 2015 SME Annual Conference & Expo in Denver, CO Feb. 15-18.

The following is a sample of what was offered at the 2015 meeting.

3D Laser MappingData collection and data analysis are

changing how mining is done. One field in which technological advancements have made safer and more efficient operations possible is through site and slope monitoring.

3D Laser Mapping, a United Kingdom-based company, was on hand at the 2015 SME Annual Conference and Expo to display its solutions for the mining industry, including its SiteMonitor4D system.

The state-of-the-art laser measurement-based system was developed in partnership with geotechnical engineers and mining surveyors, and is a simple-to-use, reliable solution that has the flexibility and performance to function in a range of monitoring applications.

The system measures and monitors the stability of rock faces, landslips and man-made structures, including ongoing, periodic measurement of volumes — stockpiles, cutbacks and waste dumps and has high-speed laser scanning for regular mapping of large areas by mounting the scanner

on a vehicle.With specifications that other monitoring

techniques cannot achieve, laser scanning opens up a new dimension in mine measurement and monitoring.www.sitemonitorsystems.com

A.R. Wilfley and Sons Inc.Founded in 1919, A.R. Wilfley and Sons Inc. has

been manufacturing dynamic-seal and static-seal pumps in Colorado for nearly 100 years, delivering its high-reliability, low-maintenance, heavy-duty process pumps and slurry pumps to the global mining industry. The family-owned company is now in the hands of the fifth generation.

“We are the dynamic-seal experts,” regional sales manager Cesar Murillo said. “Most other companies are unable to do 100 percent dynamic seals and have to use mechanical seals or packing,” he said, but Wilfley’s sealing technology does away with the need for mechanical seals and packing and their associated problems. As a result, solids and slurry handling capabilities are high, the pump can be run dry, and product dilution is eliminated. The pump can tolerate more misalignment, more cavitation, and more vibration in the pump during operation.

Besides having its own foundry, the company employs in-house personnel with advanced degrees in metallurgy who are constantly

Certified Labs The Fuel Quality Assurance program from

Certified Labs is a new five-step fuel maintenance program designed to give diesel fuel users high-quality fuel on every load. The first step provides quarterly testing of onsite storage tanks for water content, biological growth, cetane levels, cloud point, cold filter plug point, pour point and biodiesel.

The second step is the installation of the solar-direct inject pump. It delivers an accurate dilution of Diesel Mate all-season diesel fuel additive, without the need for human intervention. The pump is solar-powered, precise and reduces waste. Next, the automatic pump delivers the fuel additive to prevent operating problems caused by poor quality fuel.

At this point, Certified Labs provides an EPA-registered fuel biocide if, or when, the storage tanks test positive for biological growth. Finally, a Certified representative makes a monthly visit to monitor and service the solar-direct inject pump, to test fluid levels and to analyze the results. www.certifiedlabs.com

Cytec Industries Inc.Cytec Industries Inc. supplies chemical

reagents to the mining industry, partnering with mining companies around the world to deliver reagent solutions for the recovery and production of copper, alumina, gold, nickel/cobalt, polymetallic ores and other metals and minerals.

The company, which is celebrating its 100th anniversary this year, said the “focus has always been on enabling customers to improve productivity and reduce operating costs while meeting complex economic, environmental and metallurgical challenges.”

With shifts in global awareness and the startups of new mines in new countries, Cytec has been expanding its plants in India, Canada and Australia while adding experts in supply chain and local service requirements to its global operations. It is pursuing innovation to improve the efficiency of metal and mineral separation and extraction in ores that have reduced metal content, and to accomplish this at lower cost with less energy use. “SME is a major forum for us to share our new innovations and continue to learn about industry trends,” the company said. www.cytec.com

Fibrex CorporationFibrex Corp. manufactures custom-

engineered fiberglass composite pipes and fittings for corrosive applications at its own plant in the state of Washington and serves domestic and international markets. “We make very high-quality pipes and fittings, which means our products last longer and our clients save money over time,” said business development manager Michael Merrick.

The company has been providing quality equipment made of fiberglass-reinforced plastic to the chemical, chlor-alkali, power, and pulp and paper industries since 1982. For the mining and metallurgical industries, it produces strong, lightweight process pipes and fittings that can resist corrosion in some of the harshest chemical and temperature service environments. This year, it displayed several short pieces of fiberglass composite pipe and a dozen pipe samples. In particular, it showcased samples of industry standard tee joints and its proprietary tee joints called Integra Joint. Fibrex’s vision is to manufacture products that solve problems and that outlast its customers’ expectations. www.fibrex.com



Guardvant Inc. To help mining operations reduce accidents

and maintenance costs and increase productivity, Guardvant Inc. develops safety technology for mobile equipment, focusing on operator-fatigue monitoring systems. “Infrared cameras monitor operators for symptoms of fatigue, like high percentage of eye closure (perclos), eyes closing for short periods (microsleep), and pitch and yaw of the head,” said Erich Smidt, vice president of sales and marketing. “The onboard system has a loudspeaker to sound alerts and a seat vibration unit to provide a tactile warning. A signal will also be sent to mine dispatch with a video clip and data of the event so that the site supervisor can call affected operators to check on their welfare.”

The company’s algorithm, with high tracking and reliability and low percentage of false positives, along with its capability to integrate its technology with mine fleet management systems, differentiates it in the industry, Smidt said. In an SME Annual Conference technical session, Gold Fields, one of Guardvant’s customers, presented the results of a three-year study on the return on investment of fatigue management, carried out at Gold Fields’ Tarkwa Mine in Ghana using Guardvant’s OpGuard system. Analyzing fatigue-related incidents and direct and indirect costs, the study found a 90-percent decrease in fatigue events and approximately $1.5 million a year in cost avoidance. www.guardvant.com

Hole Products Direct-push technology (DPT) uses direct-

push (probe) rigs to inject tools and sensors into the ground to advance sampling devices and geotechnical or analytical sensors into the subsurface. Cost effectiveness, versatility and efficiency are some of the advantages of DPT, so it is often the preferred drilling method for geotechnical and environmental projects. In addition, probes produce minimal cuttings and waste — saving time and reducing overall job-site costs associated with the handling, removal and cleanup of waste associated with traditional drilling methods.

To service the direct push market, Hole Products offers Force DPT, a full line of geoprobe compatible tooling. Force DPT includes tooling systems that range from 3.2 to 11.4 cm (1.25 to 4.50 in.), soil-sampling systems, ground water sampling and assessment systems, field accessories, and more. Hole Products has in-stock inventory at multiple U.S. locations, coupled to its sales, service and distribution network. www.holeproducts.com

Open Loop Energy Inc.Open Loop Energy Inc., a specialist in

hydraulic systems, provides hydraulic services throughout the mining industry in a number of different areas. One of its focuses at the conference was to show its Digital Controlled Water Distribution System that precisely manages water distribution for large mining water trucks based on ground speed. “The patented system incorporates new technology that enables mines to properly manage their water systems and monitor what their water structure is capable of and what its actual performance is,” said business development administrator Erin Motes, who gave a presentation on the system in an SME Annual Conference technical session. “When we do that, we empower mine managers to properly utilize their assets.” In particular, users have the ability to data log their water usage for use in planning and production and in tasks such as complying with air quality permitting requirements or upgrading the utilization of their water resources.

The company champions what it calls an international fluid power society. “We have a number of individuals within our organization who are accredited instructors and technicians. We are one of three authorized Parker Denison repair centers on the West Coast, which enables us to do things for our customers that others cannot,” Motes said. www.openloop.net

Orion Monitoring Systems Inc.Orion Monitoring Systems Inc. provides

high-precision satellite monitoring systems for soil stability, subsidence and stockpile monitoring, typically running an L1-Static GPS method. “We’re exhibiting some of our later products, which feature the integration of GPS with advanced GNSS receivers, wireless technologies, solar remote power supplies and our software, which allows us to stream data in from the field stations in real time and near real time and process them in a computer to get high-precision results,” said Jeffrey Behr, president of Orion Monitoring Systems.

One of the most valuable benefits that its customers get is reliable 3D data, he said. Furthermore, compared with some other technologies that they use, Orion is able to give them more reliable results over the time frame. For instance, the reflectors used in robotic total stations are often difficult to position on the slopes of pits because of various atmospheric and weather conditions, a problem that is absent with the all-weather GPS system. The low-key L1-Static GPS method also allows Orion to sell



lower-cost hardware and to provide its customers with more points for the budget. “Another thing that sets me apart is that I have tried to tune this to simplify the installations, simplify the stations, and tune the station designs for different applications,” Behr added. www.orionmonitoring.com

PEMO PumpsPEMO submersible pumps are built with

hardalloy to tackle the most abrasive slurry and sludge produced in mining, drilling and industrial applications. Hardalloy (hard metal 800 BHN) construction also means PEMO pumps will perform and last longer for maximum mean time between repairs and excellent value in cost of ownership.

These pumps consist of a body and impeller assembly with antiabrasion coatings, as on all PEMO pumps, coupled to the heavy-duty waterproof electric fully submersible motor through a coupling cage containing the dual opposed seal with independent permanent lubrication.

These pumps are designed for use in deep wells where a vertical pump would be too costly or impossible to install.

The unique features of the internal coatings give these pumps a broad range of applications: they can pump any kind of liquid or abrasive slurry with up to 30 percent suspended solids by weight and particle size up to 20 mm (0.8 in.) in diameter.

PEMO submersed pumps are installed without masonry or special structures: they can be set on the bottom of the well or hung from a rope, chain or other suspension devices.

A float switch controls the pump, keeping it constantly covered with fluid.

The supplied power cable is 7 m (23 ft) long or longer if required, heavy duty, fully insulated and designed for the severest operating conditions.www.pemo.com

The PRiSM software enhances the company’s information and asset management software offerings in the areas of metals and mining, power and energy management, and water and waste water. www.schneider electric.com/uswww.software.invensys.com

Skycasters In the mining industry, locations are constantly

changing and conditions are often challenging, so land-based communications are not always reliable or practical. Skycasters’ VSAT allows geologists and engineers from a headquarters location or regional offices to monitor and analyze multiple sites simultaneously without traveling to each location. They can get real-time streaming data, make a VoIP call, send a fax or perform supervisory control and data acquisition using secure, virtual private networks at encryption levels that satisfy the most security-conscious company.

For business-class, high-speed Internet access, the most common system combines a VSAT X3 modem and a 1.2-m (4-ft) dish that can be installed with a nonpenetrating roof mount or pole mount. Skycasters also offers mobile and portable communications that can be mounted on a truck, RV or trailer. Turnkey portable solutions can be towed to a mining location or shipped by common carrier, and untrained personnel can set up a wireless hot spot in less than 10 minutes. Systems are designed to endure extreme conditions such as high winds, freezing temperatures, ocean storms and intense heat.www.skycasters.com

Smart Cap LLCSmart Cap was showing wearable technology

that measures the level of alertness of wearers by monitoring brainwave activity. A SmartCap looks just like any baseball cap but has sensors inside that measure the low voltages produced by the wearer’s brainwaves on the skin and then runs the readings through an algorithm, which determines the wearer’s ability to resist sleep. “It tells you where you are on a fatigue level range and how close you are to microsleep,” said business development manager Brady Marcus.

What sets the technology apart is its predictive aspect. “SmartCap tells you that you are at risk before the event,” Marcus said. “Everything else out there tells you after the fact.” The company wishes to get the word out that it has a solution for fatigue monitoring that is predictive, proactive and has been used in Australia, South Africa, South America and North America, though not specifically in mining. People who are operating vehicles for a long period of time, who have to focus all the time or who have to drive long-distance routes that are repetitious tend to get tired but find it hard to know when they are in danger, Marcus said. www.smartcap.com.au

Veolia Water TechnologiesVeolia Water Technologies has worked

extensively on the development of optimized treatment solutions for the mining industry. Some mining waste waters contain selenium, mainly in the soluble forms of selenate and selenite. Selenate and selenite can be reduced to elementary insoluble selenium by biological treatment under anoxic conditions.

Veolia offers this biological treatment through its partnership with AnoxKaldnes, a technology company that focuses on biological waste water treatment using MBRR — a moving bed biofilm reactor process. Treatment usually includes the degradation of thiocyanate and cyanide followed by nitrogen removal and sometimes chemical treatment for the removal of metals. Cyanide is toxic for microorganisms, especially to nitrifiying bacteria, and therefore needs to be degraded before nitrification can take place.

Veolia Water Technologies combines a portfolio of 350 proprietary technologies with more than 155 years of experience to provide flexible, technical solutions suited to a customer’s unique application. www.veoliawaterstna.com

Women of SME Breakfast: Pioneers in STEM Historyby Chee Theng, Technical Editor

What would you do if you were 12-years-old and having difficulty doing your homework

in the car while your parents were driving you to your next activity? If you were Becky Schroeder, you would invent an illuminated writing board and get a U.S. patent for it.

Schroeder’s story was just one of the many fascinating ones related by Jill Tietjen, co-author of “Her Story: A Timeline of the Women Who Changed America,” who was the featured speaker at the “Women of SME Breakfast: Pioneers in STEM History” event at the SME Annual Conference and Expo. She took the audience through five centuries of remarkable women and their contributions, touching on Florence Bascom (1893), the first woman hired by the U.S. Geological Survey; Lillian Gilbreth (1931), cofounder of the field of industrial engineering; Edith Clarke (1947), who published what would become the standard textbook for circuit analysis calculations; Maria Goeppert-Mayer (1963), who won the Nobel Prize in physics for her work on the nuclear shell model of the atomic nucleus and Stephanie Kwolek (1965), who invented the super-

strong synthetic fiber Kevlar.The stories reflected many of the experiences

of the more than 100 Women of SME who attended the breakfast. The world of mining, metallurgy and exploration is traditionally one in which men feature prominently, and a great number of the breakfast participants have their own stories of perseverance, creativity and independence in this understandably male-dominated world. But times are changing apace, and the Women of SME Breakfast has been changing with it. Since its start, the event has grown in both size and content. It has progressed to feature invited speakers and forums, and has become a distinct educational and networking event that continues to attract a crowd of both men and women.

Tietjen concluded her talk and opened the floor to questions from the audience by recapturing the memory of the day she met her most challenging questioner. Trained as an expert witness and toughened by years of public speaking, Tietjen is seldom at a loss for words, but the fifth-grade boy tested even her ability. At the end, the boy said, “You know, there are men in history, too.” n


Thermo ScientificThermo Scientific has

created a new personal dust monitor that is designed to help protect coal miners from the health effects of long-term exposure to coal dust. According to The National Institute for Occupational Safety and Health, there has been an alarming increase in black lung disease (pneumoconiosis), a debilitating disease caused by inhaling coal dust for a prolonged period of time.

The Thermo Scientific PDM3700 personal dust monitor is a lightweight instrument worn on a mine worker’s belt. It is

lighter, more durable and more ergonomic than the previous version, the PDM3600 monitor, and is designed specifically for use in U.S.-based mining applications. The PDM3700 monitor is engineered to provide continuous high-quality personal dust exposure information to ensure that shift-average respirable dust intake does not exceed regulatory limits. The battery-operated device provides three real-time measurements: primary current mass concentration, primary cumulative mass concentration and percent of limit.

The Thermo Scientific PDM3700 personal dust monitor also offers continuous information availability through an automatic measurement method, allowing for lower per-sample cost than with manual sampling; tapered element oscillating microbalance technology for real-time concentration data logging to identify occurrences of highest exposure; lightweight design, a decrease of 25 percent over previous model thanks to elimination of cap lamp and second battery and enhancements in hardware, software and firmware to improve radio frequency interference susceptibility, consolidation of data for MSHA reporting and numerous other capabilities. www.thermoscientific.com/endblacklung.

Wirtgen America Inc.With its surface-miner manufacturing

operations in Germany and its U.S. headquarters in Nashville, TN, Wirtgen has a 90-percent market share worldwide in the surface mining business, said Robert Bauer, director of the mining division, North America, at Wirtgen America Inc. It also is the world market leader in the road milling business, with a 68-percent market share. The privately owned company, founded in the 1960s, is now being led by second-generation Wirtgen brothers.

At its booth, Wirtgen was showcasing its smallest surface miner, the 2200 SM, an “all-rounder” with operating weight of almost 48 t (53 st) that can achieve a cutting depth of 28 cm (11 in.) over a total width of 2.2 m (7.2 ft) in soft to medium hard rock. The next model in size is the 2500 SM and the largest is the 4200 SM. The company has been doing well in the United States, having placed 50 machines in the market in the last seven years.

“Our distinguishing feature is that we are very much technical driven with high-tech equipment, very well engineered, very innovative. We always try to be on the edge of technology, trying to come up with new solutions for already known problems and to further improve our already successful machinery,” Bauer said. www.wirtgenamerica.com/us/

Weir The Weir Group has acquired Trio Engineered

Products, a Chinese-American manufacturer of crushing and separation equipment for the mining and aggregates markets. Weir currently provides pumping equipment to the mine-mill circuit. The acquisition of Trio will build upon its recent entry into the adjacent comminution segment and allow it to provide a more complete product and service offering to existing mining customers. The company sees the transaction as an opportunity to accelerate Trio’s growth through the Weir global platform and to cross-sell Weir’s product range through Trio’s sales channels in North America and China.

Founded in 1998, Trio is based in Shanghai, China, where it has two manufacturing plants. The company also has facilities in the United States. It designs and manufactures a range of crushers, screens, feeders, washers and materials handling solutions for heavy duty applications. n

Attendees got hands-on experience at the 2015 SME Annual Conference and Expo.




So many talks, so little time.One of the toughest challenges associated

with attending the SME Annual Conference and Expo is deciding how to allocate one’s resources. After accounting for keynote and plenary sessions, committee meetings, networking events, luncheons and exhibits, attending even one of the 109 technical sessions and more than 600 technical paper presentations can be a labor of love.

Many, however, managed to make it to many of the sessions, including the mineral and metallurgical processing technical session on solvent extraction, ion exchange and electrowinning.

At one point, that room was seated to near capacity, with a considerable number of the audience members standing by the walls at the back. Brittany Valera of Freeport-McMoRan Inc. was one who came early and enjoyed the session in its entirety. “Everything was pretty exciting,” she said. “I really liked the modular plants. I think the future of mining, just like what we talked about in there, lies in thinking about things like remote locations, lifetimes of plants, anything that would be reusable and sustainable; and lower-cost and user-friendly would be really beneficial.”

Michael Moats, associate professor of metallurgical engineering at Missouri University of Science and Technology, started off the session by presenting on behalf of post-doctoral student Alex Luyima, who, like many before him, had been snapped up by industry and is now working for a secondary-metals refining company in Texas. Their team studied the nucleation and growth mechanism of copper on stainless steel from synthetic acidified copper sulfate in the absence and presence of chloride ions and three commercial organic additives: Hydrostar 4208, DXG-F7 and Cyquest N-900. Current-time data were analyzed using known models, with reference to scanning electron microscope images. Good agreement was achieved between the models and SEM micrographs of deposits at a commercially relevant current density of 30 mA/cm2. The addition of 20 mg/L chloride was found to increase the size and reduce the number of nuclei. The addition of 2.5 mg/L of each additive did not change the mechanism, but all three reduced the size and increased the number of nuclei, leading to more uniform coverage of the substrate with smoother deposits produced in two-hour electrowinning experiments. N-900 had the best deposition coverage while DXG-7 was the easiest to dissolve.

Michael Free, professor of metallurgical engineering at University of Utah, discussed the effects of changes in flow rate and concentration of leaching solutions on copper ore heap leaching. In a general copper leaching operation — in which processed ore is placed on the heap and a leaching solution allowed to percolate down to give a copper-enriched solution, which is then put through solvent extraction and electrowinning to pull out the copper — size distribution, agglomeration and compaction are all important factors that influence the process.

“We have to understand how all these pull together with comminution and stacking and flows to get the ultimate performance we want,” Free said. He showed how he derived equations to calculate the probability of finding a valuable mineral particle in a liberated, partially locked or fully locked state — each with a different leaching model — in a host rock. He considered what would happen to the particle during crushing, and how the new particle size could be mathematically estimated. An area where he sees great potential is effective compression.

One of the most popular talks of the session was on a solvent extraction process to control iron in the electrolyte solutions of copper solvent extraction-electrowinning (SX-EW) systems, presented by Jack Bender, mining technology manager at BASF Mining Solutions. BASF developed the process and field-tested it with 22 tests and a pilot plant. “It was a really large project in terms of number of experiments, though not necessarily time, as things worked well right from the beginning,” Bender said. In SX-EW systems, iron is transferred from the pregnant leach solution to the EW circuit either as entrained aqueous in the organic phase or by chemical extraction of ferric ions. As the concentration of iron rises, the redox reaction of ferric to ferrous ions at the cathode consumes current, which pulls down current efficiency. To control this, copper-rich electrolyte solutions are currently bled from the systems. BASF’s new process, with a simple 1E/2S circuit configuration, removes ferric ions selectively and sends the electrolyte solution back to the EW system, providing the benefits of reduced cobalt loss, heightened current efficiency, repurposing of wash stages, and more copper plated without additional current. In reply to a question from the audience, Bender explained how the process can be adapted to treat “a weak solution that has too much iron.”

More than 100 technical sessions at 2015SME Annual Conferenceby Chee Theng, Technical Editor


Andrew Smethurst, senior metallurgist at Huntsman Corp., demonstrated the use of Huntsman’s Polysil polyether coagulants as a means to reduce colloidal silica and crud formation in hydrometallurgical processes. The digestion of minerals in strong acids or at elevated temperatures can result in the release of large amounts of silicic acid that can polymerize in solution to form colloidal silica. Colloidal silica can interfere with flocculation, initiate crud formation, negatively affect extraction kinetics, increase phase disengagement times, and cause other problems in solvent extraction. Polysil’s “lock and key” relationship with the surface of colloidal silica enables the colloidal silica particles to be coagulated and grown to the point that they can be flocculated and removed from leach liquors. The results are lower concentration of colloidal silica in solution, improved process efficiency, and reduced reagent losses by minimizing crud formation. Polysil RM1250 has been applied on a plant scale at Olympic Dam and Nyrstar’s Port Pirie smelter.

Metallurgist Colt Everly showed how Freeport-McMoRan shifted the focus at its Sierrita Mine from the historical method of managing chloride concentrations in the SX/EW process by using reactive techniques such as increasing electrolyte bleeds and rectifier amperages to the more effective, proactive approach of limiting the introduction of chloride into the electrolyte solution. Elevated chloride concentrations have undesirable outcomes such as lower current efficiency, higher handling costs at rod plants and smelters, accelerated anode corrosion, loss of cobalt due to increased electrolyte bleeding, degradation of high-density polyethylene piping, and heightened corrosion. But maintaining high bleed rates and high amperage settings had been a challenge with declining PLS grades, so keeping chlorides out of the electrolyte solution had become imperative. Everly illustrated the effectiveness of reducing aqueous entrainment, optimizing mixer speed and wash-stage efficiencies and improving

organic quality to reduce the transfer of chlorides to the solution. The dynamic model can be applied to any plant with chloride or impurity problems.

Rami Saario, senior product manager at Outotec, explored the possibility of applying modularization in the mining industry to counter challenges such as declining ore grades, deposits in remote locations that lack infrastructure and labor resources, and commodity price uncertainties that make investment decisions difficult. Modularization principles offer solutions that reduce uncertainty, yet its suitability is often questioned and it is perceived to entail complex engineering and to increase a project’s overall cost, he said, with modularization now typically applied to only the most extreme cases. Outotec’s answer is to use standard modules to simplify the engineering, shorten lead times and cut project capital costs. To evaluate the potential benefits of modularization, Saario presented a case study of a modularized Outotec VSF X SX model plant featuring prefabricated, transportable settler modules, which provide scalability, accuracy and cost efficiency; standardized sales and delivery processes; and lower risks, shorter lead times and high quality. He showed benefits from the perspectives of cost efficiency, sustainability, operation and maintenance, and implementation.

Cytec Industries’ Acorga CB1000, a process aide that enables higher dosages of clay to treat organics and allows the enhanced efficiency of existing filtration equipment, has already been implemented at two commercial copper SX operations. In copper SX, managing the quality of the organic phase is important for optimal performance, but limits are being pushed due to increases in throughputs to counter declining ore grades, coupled with advances in plant design and practice that have reduced organic losses. Clay treatment of plant and recovered organics at optimal dosages is critical but achieving optimal dosages using existing filtration capacity and practice can be difficult. Cy Cooper of Cytec presented a study analyzing the results of commercial trials comparing treatment using a diatomaceous-earth body feed and treatment using CB1000, which enabled a doubling in clay dosage. The process aide returned a more clarified product and raised Cu:Fe selectivity. In an analysis of the time needed to restore the quality of 450,000 gallons of plant organic inventory, 28 days are needed with 4 wt percent clay dosage, down from 72 days at the typical 1 wt percent dosage.

Freeport-McMoRan’s Valera found the CB1000 results interesting. “I’m at a plant in New Mexico right now, and there might be some benefit there for using a newer reagent like that,” she said. n

IntroductionDespite more than 30 years of

regulation, noise-induced hearing loss continues to be one of the most prevalent diseases in the mining in-dustry. High levels of noise—above 90 dB(A)—are generated by the powerful mining machines used to extract mined material. Furthermore, operators’ close proximity to these machines in the confined environ-ments typical of underground mines contributes to the operators’ over-exposure to noise. According to a study conducted by the U.S. National Institute for Occupational Safety and Health (NIOSH), about 80% of miners have hearing impairment by retirement age (Franks, 1996). These numbers are alarming when com-

pared with the approximately 10% of workers with hearing impairment by retirement age who were not overex-posed to occupational noise.

One set of machines whose opera-tors are overexposed to noise is long-wall mining systems. These systems are used to extract approximately half of the national underground coal production. Although they vary in dimensions and capacity, the basic components of the longwall mining systems that we analyzed are: long-wall shearer, armored face conveyor, stageloader and hydraulic shields.

Previous research conducted by the U.S. Bureau of Mines determined that the most significant sound-radi-ating components contributing to the noise dose accumulated by longwall

abstract ■ One of the most pervasive diseases in the mining industry is noise-induced hearing loss. The exposure of miners to noise levels above the permissible exposure level results in hearing loss in approximately 80% of coal miners by retirement age. In this context, the U.S. National Institute for Occupational Safety and Health (NIOSH) is conducting research to develop noise controls for longwall mining systems, which are used to extract half of the national underground coal production.

From field measurements, previous research determined that the dominant sound-radiating components at the shearer of a longwall system are the two cutting drums used to remove coal. Due to the dimensions and complexity of longwall mining systems, the NIOSH project developed a validated finite element model of the cutting drum to use in predicting the sound radiated by the drum due to the excitation forces experienced in underground operations. This same model will be used to develop engineering noise controls for the drum. The excitation forces arise from the interaction of the cutting bits and the coal and are transmitted to the cutting drum through the bit holders. Due to the adverse conditions at the face, and a lack of instrumentation approved for underground use, the operational coal cutting forces have not been assessed before. To this end, NIOSH, in collaboration with michigan Technological University, developed a self-contained, intrinsically safe instrumented bit to measure these forces.

This paper describes the development of the instrumented bit and the measuring of operational coal cutting forces at three working coal mines. The measurements revealed that the forces have a flat spectrum, representative of the impact nature of these forces, up to around 100 Hz. above this cutoff frequency, the force magnitude decreases at a rate proportional to the inverse of frequency squared.

shearer operators were the two cutting drums (Pettitt and Slone, 1986). Therefore, NIOSH is currently conduct-ing research to develop engineering noise controls for these cutting drums. To this end, numerical models of the cutting drums are being used to predict their structural and acoustic response. However, before these numeri-cal models can be used to explore noise control alterna-tives, knowledge of the forces that excite the cutting drum structure into vibration is needed. These forces originate from the interaction between the cutting bits and the coal and are transmitted to the cutting drums through the bit holders.

This paper presents the development of an instru-mented bit to measure coal cutting forces to be used as input into finite element models of the shearer drum dy-namics. When combined with boundary element models to predict noise radiation from the vibrating drum, it will be possible to evaluate modifications to the drum to re-duce the noise exposure of miners. Coal cutting forces were measured at three different mines, and typical coal cutting forces measured at a longwall shearer in opera-tion are presented.

Description of longwall mining systemLongwall systems are sets of machines that work to-

gether in full synchrony to extract ore from underground mines. Although there are two basic types of longwall systems—shearers and ploughs—in the United States, ap-proximately 98% of longwall mines use shearers (Long-wall census table, 2013). For this reason, the work pre-sented in this paper focuses on longwall shearer systems.

These systems are mainly used in coal mines and a few trona mines across the United States; therefore, the terms coal and ore will be used interchangeably throughout the paper. A longwall system (Fig. 1) comprises the following components: a shearer that traverses back and forth along the face cutting coal; an armored face conveyor (AFC) that runs along the face and transports the cut coal to the stage-loader; powered, self-advancing longwall shields that pro-vide temporary roof support for the shearer and the AFC; and a stageloader that, after crushing the coal, loads it onto a belt conveyor to be taken out of the mine. The shearer is 8-12 m (26-39 ft) long, and by virtue of its ranging arms can perform cuts that are 2-6 m (6.6-20 ft) high. Each shield is 1.5-2 m (4.9-6.6 ft) wide; therefore, on a typical 400-m (1,312-ft)-long face there are more than 200 shields provid-ing temporary roof support. Since the AFC runs along the face, a typical AFC can be 400 m (1,312 ft) long.

The longwall shearer is one of the main components of a longwall system. It is usually controlled by two opera-tors who move along with it as it traverses the face: one operator per cutting drum. The cutting drum’s function is to cut the coal and load it into the AFC. In order to effectively accomplish these two tasks, the shearer is pro-vided with two rotating cutting drums that, due to their locations with respect to the headgate and tailgate en-tries, are called the headgate drum and the tailgate drum, respectively. Generally, the outer diameter of the drums is approximately two-thirds the seam thickness. The leading drum cuts the top portion of the seam, while the trailing drum not only loads the spilled coal but also cuts the floor and the remaining uncut one-third of the seam.

Resumen ■ Una de las enfermedades más extendidas en la industria minera es la pérdida de audición inducida por el ruido. La exposición de los mineros a niveles de ruido superiores a los niveles de exposición permisibles resulta en la pérdida de audición de aproximadamente el 80% de los mineros del carbón a la edad de jubilarse. En este contexto, el Instituto Nacional para la Seguridad y Salud Ocupacional (NIOSH, por sus siglas en inglés) está realizando investigaciones para desarrollar controles de ruido aplicados a los sistemas de minado de tajeos largos. Este método de minado es usado para extraer la mitad de la producción nacional de carbón subterránea.

a partir de las mediciones en campo, se determinó en investigaciones anteriores que los componentes dominantes que generan sonido en el cizallador de un sistema de tajeos largos son los dos tambores de corte utilizados para extraer el carbón. Debido a las dimensiones y complejidad de los sistemas de minado de tajeos largos, el proyecto NIOSH desarrolló un modelo de elementos finitos validado del tambor de corte para utilizarlo en la predicción del sonido generado por este debido a las fuerzas de excitación experimentadas en las operaciones subterráneas. Este mismo modelo se utilizará para desarrollar controles de ingeniería para el ruido del tambor. Las fuerzas de excitación surgen de la interacción de la broca de corte y el carbón, y se transmiten al tambor de corte a través de los sujetadores de brocas. Debido a las condiciones adversas en el frente y la falta de instrumentación aprobada para uso subterráneo, las fuerzas operativas de corte de carbón no han sido evaluadas anteriormente. Para este fin, NIOSH, en colaboración con la Universidad Tecnológica de michigan, desarrolló una broca instrumentada autónoma con seguridad intrínseca para medir estas fuerzas.

Este artículo describe el desarrollo de la broca instrumentada y la medición de las fuerzas operativas de corte de carbón en tres minas. Las mediciones revelaron que las fuerzas tienen un espectro plano, algo característico de la naturaleza del impacto de estas fuerzas, hasta alrededor de 100 Hz. Por encima de esta frecuencia “cutoff”, la magnitud de la fuerza disminuye a una razón proporcional al cuadrado de la inversa de la frecuencia.

Longwall shearer cutting drum. The longwall shearer cutting drum examined in this study consists of a cylindri-cal body with a 0.987-m (3.2-ft)-outside-diameter, 1.067-m (3.5-ft)-high and 0.05-m (0.2-ft)-thick wall. Inside this cylindrical body, there is a circular mounting plate 0.10 m (0.3 ft) thick having a square opening at the center of the cylinder (Fig. 2). The drum is fully made of steel and weighs 4,707 kg (10,377 lb). Around the cylindrical body, four helical vanes are welded, starting in the face ring and winding around the cylindrical body toward the discharge side of the drum. The function of the helical vanes is to push the cut coal into the AFC as the drum rotates. The vanes have a 1.91 m (6.3 ft) outside diameter. On the out-ermost edge of the vanes, there are 28 bit holders that position the cutting bits at various angles of attack. There are also 12 bit holders on the outermost edge of the face ring and four bit holders in the flange of the face ring, making a total of 44 bit holders. Water is carried through

conduits inside the vanes to the bit holders, where the wa-ter is sprayed through nozzles to reduce the risk of igni-tion of mine gases and for dust control purposes.

Development of instrumented bitPrevious research had determined that the cutting

drums are the dominant sound-radiating components on a longwall shearer. These drums are set into vibra-tion by the excitation forces that arise from the interac-tion of the cutting bits with the coal and transmitted to the drum through the bit holders. Therefore, knowledge of these forces is critical for noise control development purposes. However, due to the adverse conditions at the face while the drum is in operation—that is, as the drum is sumped into the coal—vibration and force measure-ments are extremely difficult to conduct on an operating drum using commercially available force and acceleration transducers. In addition, the presence of explosive gases

at the coal mine face, as well as a lack of instrumentation approved by the U.S. Mine Safety and Health Administra-tion (MSHA) for underground use, further restricts the ability to perform any type of vibration and/or force mea-surements. Therefore, there was a need to develop cus-tom-made apparatus to measure these coal cutting forces while the shearer is in operation.

To address the above physical constraints and to com-ply with explosion-prevention requirements, NIOSH, in collaboration with Kennametal and Michigan Technolog-ical University, developed a self-contained, intrinsically safe instrumented bit to measure in situ operational coal cutting forces. This instrumented bit consists of two parts: the bit hardware and the electronics. An application for a permit to use the instrumented bit at the face of a coal mine was filed with MSHA as required by law (Title 30 of the Code of Federal Regulations, Part 18.82), upon which NIOSH was granted the relevant experimental permit (MSHA Experimental Permit 18-EPA110001-0).

Bit hardware. A standard longwall cutting bit is at-tached to the shearer drum by means of a bit holder and a sleeve (Fig. 3). The bit holder is welded to the shearer drum, and the sleeve is pressure-fitted into the bit holder. The bit is held in place with a snap ring or other retention mechanism that permits the bit to freely rotate inside the sleeve. This configuration allows the sleeve and bit to be replaced when worn.

The instrumented bit consists of a bit-and-sleeve as-sembly in which the bit shank has been cut and the re-maining bit is welded to the sleeve (Fig. 4). To install the sensors, a hole with diameter of 5 mm (0.2 in.) is drilled into the bit from the shank to 5 mm (0.2 in.) from the tip. The hollow space provided by the sleeve is closed by a threaded cap. The bit-sleeve assembly is further provided with two anti-rotation tabs. These tabs engage onto the bit holder and prevent the bit from rotating during the data acquisition process (DAQ). The modifications to the bit to add the sensors are small. Since the tip and main load-bearing components of the bit assembly are not altered, it is anticipated the measured loads accurately represent the loads seen by unmodified bits. One of the main advantag-es of the bit-sleeve configuration is that installation into an operating shearer can be performed very rapidly—in less than five minutes—thus minimizing downtime of the longwall shearer. Upon data collection, the instrumented bit can be retrieved and replaced by a standard sleeve and bit pair.

Instrumentation. Two versions of the instrumented bit were fabricated. Both have a three-channel data acqui-sition system fitted in the hollow space. The system can sample data at a rate of 100 kHz and is powered by a 9.6V NiMH battery fitted inside the hollow space provided by the threaded cap. The first version is equipped with a PCB Piezotronics model 3991A3060KG MEMS accelerometer and two full strain gauges. The piezoresistive accelerom-eter and strain bridges were calibrated to measure the ac-celeration along the axis of the bit, the force along the axis of the bit, and the bending force on the plane of sym-metry of the bit holder (Fig. 5). The second version con-

tains three strain gauges that were calibrated to measure forces in the three directions: axial force, bending force and transverse force. The second version was built after a sensitivity analysis showed that all three force compo-nents are important in terms of sound radiation in the frequency range of interest (20 Hz to 2,000 Hz) (Yang et al., 2013a).

ResultsThe instrumented bit was used to measure coal cutting

forces at three different mines. For brevity, only typical results obtained using the second version of the instru-mented bit at one mine are presented in this paper. Figure 6 shows the time data of the coal cutting forces measured by the second version collected at a mine in West Virgin-ia. During this test, the longwall shearer drums were only cutting coal and not roof material (rock). The web depth during this test was 0.6 m (2 ft), the tramming speed of the shearer was 9 m/min (29.5 ft/min), the ranging arm angle was approximately 20°, and the instrumented bit was mounted in a bit holder located midway between the face ring and the gob side of the drum. It is apparent from Fig. 6 that the forces in the axial direction have the high-est amplitude, reaching approximately 20 kN (4,500 lb), followed by the bending forces with ±6.7 kN (±1,500 lb) and the transverse forces also with ±6.7 kN (±1,500 lb). A sharp increase in amplitude is seen every time the bit engages with the coal during the cutting process, followed

by a sharp decrease in amplitude while the drum com-pletes a rotation and the bit is not engaged with the coal. During the data acquisition process, the shearer drum was rotating at approximately 55 rpm, which is reflected on the period of the amplitude of the peaks.

The time data were post-processed and converted into the frequency domain using Fourier transform in order to assess the frequency content of these forces. From Fig. 7, which shows the power spectral density of the data shown in Fig. 6, it can be seen that the force amplitude is relative-ly constant up to around 100 Hz. From this point on, the amplitude of the force decreases at a rate inversely pro-portional to frequency squared. Furthermore, in the axial force spectrum, two harmonic components are observed at 3,582 Hz and 7,164 Hz, respectively, while in the bend-ing force spectrum, two harmonics are observed at 3,594 Hz and 7,188 Hz and a bump is observed around 4,648 Hz, and in the transverse force spectrum, the harmonics are present at 3,691 Hz and 7,382 Hz and a bump is observed around 4,677 Hz. It is suspected that these harmonic com-ponents are related to the natural frequencies of the first structural modes of the bit holder.

As noted previously, these measured forces will be used as input into a finite element model to describe shearer drum vibration. In turn, a boundary element mod-el of the cutting drum (Yang et al., 2013b) will be used to predict its acoustic radiation characteristics (Yang et al., 2013a). These combined models of the cutting drum will

be used to explore various noise control solutions such as bit isolation, damping treatments and structural modi-fications. Initial results indicate that structural modifica-tions of the helical vanes and the face ring may provide as much as a reduction of 3.7 dB in sound power radiated by the drum (Yang et al., 2014).

Conclusion

An instrumented bit was developed by NIOSH that overcomes the various difficulties of measuring the coal cutting forces encountered at longwall shearers in op-eration. The developed bit consists of a self-contained, intrinsically safe instrumented bit capable of measuring coal cutting forces in three orthogonal directions at a 100 kHz sampling rate. This bit was used to assess coal cutting forces at three different mines with longwall shearers in operation.

Typical results show that these forces have a relatively constant low frequency amplitude up to around 100 Hz. Above 100 Hz, the amplitude decreases at a rate that is inversely proportional to frequency squared. Also, two harmonic components are observed around 3,600 Hz and 7,200 Hz, respectively, which are suspected to be the natural frequencies of the first structural modes of the bit holder. The high amplitude resonances at these frequen-cies could be an indicator of a strong noise source due to the pure tone response and high structural response. These measured forces will be used as input into finite element models of the cutting drum to compute its dy-namic characteristics. When combined with boundary el-ement models to predict noise radiation from the vibrat-ing drum, it will be possible to evaluate modifications to

the drum to reduce the noise exposure of miners. Initial results show that structural modifications of the helical vanes and the face ring have the potential to provide noise reduction of up to 3.7 dB in sound power radiated by the cutting drum. ■

IMPACT — educating Boy Scouts about miningby Karen Rose, member, MEC Committee and the Kentucky Coal Association

The Introduction to Mining Practices and Coal Technolo-gies (IMPACT) program was conceived by Dave Moss,

vice president of the Kentucky Coal Association (KCA) and was developed in cooperation with the Friends of Coal-KY(FOC), KCA and the Bluegrass Council of Boy Scouts of America (BGBSA). IMPACT is a weekend campout for Boy Scouts and Venturer Scouts atop a reclaimed surface coal mine in Eastern Kentucky owned by Kentucky River Properties, a KCA member. FOC and KCA members volunteer their time, equipment and facilities to teach the scouts about coal mining.

The event begins with a campout on Friday night that is not for the faint-of-heart. Conditions on top of the re-claimed mine site are generally cold and blustery. FOC, KCA and BGBSA arrange activities throughout the day on Saturday, which include the IMPACT class. FOC, KCA members and mining engineering students from University of Kentucky’s Norwood Student Chapter of SME lead the coal class. The classes are rotated hourly to accommodate the nearly 700 scouts that attend. The annual Coal Campo-ree began in 2011 with approximately 400 campers. FOC intends to expand the camporee to other scout councils

throughout the coal fields.

IMPACT discusses the formation of coal, the various coalfields, how coal benefits our daily life, health and safety, reclamation and many more topics. Instructors use poster board displays, safety equipment and other visual aids to engage the scouts, with plenty of time for questions.

In the past, mine rescue teams provided entertainment and education. Members of the team dressed in full gear, discussed the many hours of training and dedication re-quired for this job as well as why these miners are vital to any operation. Some of the more curious scouts tried on various pieces of rescue equipment.

The scouts also engage in activities such as black-powder rifle and shotgun shooting, three-person sling shot, hatchet throwing, knot and lashing tying, and geocaching. The campout comes to a close on Saturday night in typical scout fashion with a cracker barrel. The scouts leave with

Stephen G. Hardcastle is the recipient of the 2015 How-ard L. Hartman Award for his exemplary contributions

to mine ventilation literature in the technical areas of con-trolled recirculation in mines, in optimization of mine ven-tilation through ventilation-on-demand and related strate-gies, and in the management of heat stress in underground mines. In addition, Hardcastle’s continued and significant support of the U.S./North American Mine Ventilation Sym-posia has been an important element of its success.

Hardcastle attended the University of Nottingham, England, where he worked with Malcolm J. McPherson, who gave him his foundation in mine ventilation and a stronger interest in the mining field. His Ph.D. research was on studies into the wider application of controlled recircu-lation of air in mine workings.

After completing his degree, Hardcastle moved to Can-ada as a research scientist at the Canmet Mining Research Laboratory at Elliot Lake, ON working on dust exposure, diesel particulate exposure and control of these pollutants in underground mines. In 1993, he transferred to the Can-met laboratory at Sudbury, ON and was appointed chief of mine ventilation research and senior research scientist, ven-tilation specialist in 2004.

Since his move to Sudbury, Hardcastle has become an expert on ventilation-on-demand strategies and human reaction to heat exposure in underground mines. He has many publications in these two areas of research. He has been invited to present his research at mine ventilation symposia and has often been a session chair or keynote speaker. n

SMEF outreachThe Minerals Education Coalition (MEC) is posi-

tioning itself to be a clearinghouse for all relevant K-12 education about minerals and mining and a resource for

developing new curricula to fill identified gaps in the K-12 educational spectrum. It will also be an outreach resource for volunteer advocates in K-12

classrooms and to the teachers who attend National Sci-ence Teacher Association conferences.

The Miners Give Back program is excited to partner with Engineers Without Borders (EWB). EWB has a

long history of providing global outreach through sustainable en-gineering projects. Miners Give Back is committed to supporting world-wide initiatives focused on humanitarian efforts. The goal is

to contribute to improving the lives of individuals on a global level.

Rebuilding the faculty pipelineThe Ph.D. Fellowship and Ca-

reer Development Program has been launched and the selection committee is currently reviewing applications. SMEF is excited about this new endeavor and will provide updates as we progress in the selection process during the sum-mer. This program addresses the absence of a viable pipeline to replenish current faculty vacancies and future vacancies due to retirements during the next decade in U.S. mining schools.

The Ph.D. Fellowship and Career Development Pro-gram will provide the financial support needed to acquire a doctoral degree in the field of mining engineering, min-eral processing or extractive metallurgy at a U.S.-accredit-ed university. Qualified candidates are those with industry experience and a desire to pursue an academic career.

The Academic Career Development Grant provides tenure-track assistant or associate professors with the fi-nancial support needed to participate more fully in activi-ties such as research, publication and professional service, which are necessary to achieve tenure and promotion.

Initial financial support for these programs has been provided by Robert S. Shoemaker, Freeport-McMoRan, Kinross and SME. For more information, please visit www.smenet.org/academicgrants.

The women’s mucking team from the Missouri Uni-versity of Science and Technology (S&T) earned first

place in its category at the 37th Intercollegiate Mining Competition. The team successfully defended its title as world champion in a competition designed to test skills in events based on mining techniques used in the late 19th and early 20th centuries. The event was held March 25-29, 2015 at the Western Australia School of Mines in Kalgoor-lie, WAS, Australia.

Missouri S&T sent four teams to compete against more than 50 teams from the United States, Australia, Canada, England and Brazil. Students competed in timed events, such as gold panning, surveying, hand mucking, hand steel-ing, track standing, Swede sawing and jackleg drilling. Mis-

Missouri S&T women’s mucking team wins world championship

souri S&T’s co-ed team earned sixth place, while its men’s A and B teams earned 12th and eighth place, respectively.

First held in 1978, the games were created to honor 91 miners who died in a fire at the Sunshine Mine in 1972. The competition celebrates traditional mining practices and helps create a global community of mining students. Mining colleges and universities around the world rotate hosting the mining competition.

The members of the winning women’s team are: Aubry Brown, a junior in mining engineering; Molly Clement, a se-nior in mechanical engineering; Deanna Fitzgerald, a senior in mining engineering; Kelsey Garrett, a senior in mining engineering; Jennifer Holloway, a junior in mining engi-neering and Abigail Pfaff, a junior in mining engineering. n


SME NewsCoal Division Views

The regular meeting of the Coal & Energy Division’s (C&E) Executive Board was called to order by Nikky

LaBranche at 9 am on Feb. 15, 2015 at the SME Annual Con-ference & Expo in Denver, CO. Attendees included: Kramer Luxbacher, Mike Myers, Robert Kudlawiec, Susan Bealko, Jurgen Brune, Steve Tadolini, Vaibhav Raj, Richard Wag-ner, Matt Furniss, Thomas Gray, George Luxbacher, Manoj Mohanty, Tathagata Ghosh, Paul Conrad, Michael Trevits, Gary Buchan, Joe Zelanko, Y.P. Chugh, Vladislav Kecojevic, Dragon Bogunovic, J.D. Wientjes, Charles Beasley, Royce Watts, Dan Alexander, Anthony Iannacchione, Sukumar Bandopadhyay, Thomas Novak, Jacob Carr, Barbara Arnold and Heather Gravning, SME staff. The agenda and the min-utes of the previous meeting were approved. Attendees were introduced.

Open issuesManoj Mohanty inquired about the ad hoc committee

for succession. LaBranche indicated there was nothing to report from that committee. Tom Novak inquired about the status of the Health & Safety Committee. Jürgen Brune gave an overview of the issues — essentially, whether the Health & Safety Committee should be granted division status, with the concern that it might attract members and programming from other divisions. The C&E Division has traditionally had excellent programming in health and safety. Joe Zelanko attended the Structure and Governance Strategic Commit-tee meeting and told them that creation of this new division could negatively impact the C&E Division. Division status will be recommended to the SME Executive Board.

Division FinancesThe ending balance is higher this year and finances of the

division are healthy.

Old BusinessScholarships — Robert Kudlawiec reviewed the scholar-

ship recipients. Dan Alexander suggested the division consid-er giving more scholarship money, as the guidelines indicate that 5 percent of the fund can be awarded, which is equal to $31,000. This year, approximately $26,000 was awarded.

George Luxbacher suggested that the committee consider supporting the new SME Ph.D. Fellow-ship and Faculty Career Program. Kudlawiec said the money available should be allocated to scholarships. Michael Trevits sug-gested that some of

ExcerptsfromtheminutesoftheC&EExecutiveBoardmeetingby Kramer Luxbacher

the money donated to the Foundation should be earmarked for the Ph.D. program.

Technical program — Sukumar Bandopadhyay reported that 22 sessions and 121 papers are included in this year’s program. Standard format letters were eventually sent to international authors. This issue was a problem that was discussed at the midyear meeting. Trevits suggested that the new program chair, Drew Schaeffer, should reach out to the Research Council Chair, Abani Samal, to help coordinate the research and development/innovation sessions. LaBranche reviewed the plans for the upcoming C&E luncheon, includ-ing sponsors and the speaker.

LaBranche indicated that this year’s goal was to have program area chairs with session chairs under them. There were some Abstract Central issues that caused additional problems. Gary Buchan felt that communication with chairs was not timely. Susan Bealko stressed the importance of re-cruiting young and inexperienced co-chairs. LaBranche and Richard Wagner spoke of the importance of working with the Young Leaders Committee to ensure that they have op-portunity to contribute to the technical sessions and to avoid overlap between relevant sessions.

Open committee positions — LaBranche reviewed the open positions in the blue book. She indicated that the nomi-nating meeting is in the afternoon and welcomed expression of interest prior to that.

New SME website — Heather Gravning reviewed changes to the website, and she indicated that members will be able to choose two divisions and two sections. The launch is scheduled for March 9 (now July 13). Profiles will come from the new database, which will allow direct input from members. Members will also be able to give feedback on the new website. The conference café in the exhibit hall will be demonstrating the new website.

New BusinessBise scholarship — LaBranche announced the death of

Christopher Bise, Department Chair, Mining Engineering, West Virginia University. A moment of silence was observed. His contributions to the C&E Division were recognized. Trevits, Brune and Bandopadhyay suggested a moment of silence be observed at the luncheon and that a photo be pro-vided. Bandopadhyay proposed that a scholarship be started in his memory. Tom Novak moved that Bandopadhyay inves-tigate formation of such a scholarship and the motion car-ried. An ad hoc committee was formed with Bandopadhyay as chair and Bealko and Brune as members.

AusIMM — LaBranche discussed her involvement with AusIMM and asked if there were any ideas for collabora-tion between the C&E Division and AusIMM. Mohanty suggested collaboration in the technical sessions. Trevits mentioned the Queensland Safety and Health Conference has requested that we invite one (or more) of their award

CHRISTOPHER J. BISEAn appreciation by Raja V. Ramani, professor emeritus of mining engineering, The Pennsylvania State University, and Sukumar Bandopadhyay, professor of mining engineering, University of Alaska, Fairbanks

The death of Christopher Bise on Feb. 13 in Denver, CO while attending the 2015 SME Annual Conference &

Expo has left the thousands who knew him, including the two of us, with a sense of loss that is not easy to accept. We knew him from the time he was a graduate student at Penn State. We were witness to his dedication and perseverance to achieve his best in all that he undertook, qualities that made him the leader of his colleagues in several profes-sional arenas.

Bise was born in Philadelphia, PA on Aug. 16, 1950, the only child of Jessee Banner Bise and Doris Helen Bise. He often spoke of the fun-filled, good times while growing up amidst the culture, history, sports and museums that the City of Brotherly Love had to offer. This exposure was in-strumental in his developing a keen interest and expertise in many activities, including music, ceramic art, weightlift-ing, racquetball, running and cycling.

Bise attended Virginia Tech (VPI) to pursue a degree in mining engineering, which he obtained in 1972. At VPI, he was active in the VPI Cadet School and was the drum major of the VPI cadet band, the Highty Tighties. He continued to be the Highty Tighties’ alumni band drum major from 1975 to 2010, when he was promoted to drum major emeritus and performance officer by the alumni group.

While working as a resident engineer for the Consoli-dation Coal Co. at its underground operations in eastern Ohio, Bise took a part-time job teaching mining at a local, two-year technical college. This turned out to be the begin-ning of Bise’s outstanding journey as a distinguished aca-demic in mining engineering. At the time of his unexpected death, he had just accepted a position as the deputy director of the Western Australian School of Mines. He was looking forward to the challenge of moving to Australia and assum-ing a leadership role at the historic institution.

Immediately prior to this, Bise was the Robert E. Murray Chairman of mining engineering at West Virginia University. He had joined WVU in 2006 as the Charles T. Holland Distinguished Professor of mining engineering and chairman of the Mining Engineering Department. He is credited with significantly increasing the undergraduate enrollment in the program and with establishing a study abroad program in China. The students recognized his lead-ership and teaching qualities with the Outstanding Advisor award for providing a challenging atmosphere for student growth and development.

For more than 30 years of Bise’s professional career, The Pennsylvania State University was his home. There, he obtained his M.S. (1976) and Ph.D. (1980) degrees in mining engineering and made several of his noteworthy contribu-tions to mining and industrial health and safety in academic and administrative capacities. Starting as an instructor in the mining engineering program in 1976, he was promoted to professor in 1991, appointed Centennial Professor in 1994 and Deike Chair in Mining Engineering in 2001. He

was a superb lecturer at all levels, whatever the subject matter. He developed sev-eral new undergraduate, graduate and continuing ed-ucation courses. He chaired the mining engineering program from 1993 to 2006 and the Penn State Miner Training Program from 2001 to 2006. In 1996, he designed and developed a new under-graduate major, industrial health and safety, and served as the program chair. To fur-ther add to his considerable knowledge and expertise in the industrial health and safety area, particularly in environmental health, he took a sab-batical leave and formally enrolled at the Johns Hopkins University. In 1998, he earned a master’s degree in health science in environmental health engineering.

At the university level, Bise was first elected senator in 1992 by the faculty of the College of Earth and Mineral Sci-ences. He continued to be the choice of his colleagues every four years until 2006. He chaired a number of major com-mittees of the faculty senate, ultimately becoming the chair-man of the senate in 2003. He was chair of the university’s Promotion and Tenure Committee in 2000-2001. He was an award-winning teacher, much admired by his students and colleagues across the campus for the quality time that he dedicated to their causes in the classroom and outside. Bise retired from Penn State in 2006 with the title of professor emeritus of mining engineering and industrial health and safety.

Bise was active in research, particularly in the areas of mine planning and design, health and safety, environmental protection and miner training. He directed a number of stu-dents to advanced degrees in mining, mineral engineering management and environmental pollution control. While he had an extensive publication record in several profes-sional and technical journals, he is widely recognized for the two books he edited on American mining practices — Coal Mining Technology, Theory and Practice, 1983 and Modern American Coal Mining: Methods and Applications, 2013 — and the one book that he authored, Mining Engineering Analysis (1986 and 2003), all published by SME. His ser-vices were in constant demand by public and private agen-cies as a reviewer, consultant or a legal expert. He was a registered professional engineer in Pennsylvania and West Virginia and a certified mine safety professional. He devel-oped resources and taught classes to aid aspiring students to prepare for such certifications.

Bise joined SME in 1971 and distinguished himself in the depth, breadth and quality of his service to the mem-

BISE


SME Newsbers. He served on more than 40 committees in almost all spheres of SME activities. He was chair of the Education Board and the Coal & Energy Division, and was a member of the SME Board of Directors.

In 2005, he became the first editor-in-chief of the Peer Review Editorial Board for technical papers published in Mining Engineering and SME Transactions. In recogni-tion of his outstanding contributions to the profession and SME, he was honored as a Distinguished Member of SME, class of 2001. He was a member of several other profes-sional and technical societies, including the Society of Pro-fessional Engineers (member 1990), the National Academy of Forensic Engineers (member 1990), the International Society of Mine Safety Professionals (ISMSP 1996) and the American Society for Engineering Education (2007). He was also a member of the honor societies Phi Kappa Phi and Tau Beta Pi.

Bise received several prestigious awards for excellence in teaching, research and service. The Virginia Tech Depart-ment of Mining and Minerals Engineering recognized him with its distinguished alumni award in 2000. In addition to the student-nominated teaching awards from Penn State and WVU, in 2003 he received SME’s Ivan Rahn Education Award and, in 2011, he received AIME’s Mineral Industry Education Award. In 2005, he received the SME Howard

Eavenson Award, and in 2012 he received the AIME Ers-kine Ramsey Medal for his multi-dimensional contributions to the American coal industry. In 2003, ISMSP presented him with the Al Geiser Award for his contributions to the field of mine safety. In 2014, Penn State’s Department of Energy and Mineral Engineering honored him with the Stefanko Distinguished Alumni Award, a most appropriate recognition for one who had edited the writings of Profes-sor Stefanko into a book for SME in 1983.

We would be remiss if we did not mention the side of Chris Bise that was seen by very few. His caring attitude to the senior citizens who lived alone and who needed as-sistance was much appreciated by his fellow tenants in the apartment and housing complexes where he lived before he moved to his own home. Bise took care of his aging parents with a sense of dedication and devotion that was exemplary. He ensured that their golden years were spent in comfort near him and that their needs were personally attended to by him.

Bise was a great student, a master teacher, an endearing colleague, a dear friend and, most of all, a caring person. He lived a good life, a life of fun and travel, and leadership and service. We will miss him. The mining community worldwide will miss his enormous services to the profession. May he rest in peace. n

winners to our conferences and that they would reciprocate. The Innovation Award winner from that conference will be announced at the SME Banquet. Brune mentioned that John Hayden should be involved in these efforts.

Steve Tadolini was recognized for donating his ground control award this year to the scholarship fund in the amount of $5,000.

Marsden visit — John Marsden, 2015 SME president, visited the meeting and discussed changes to the industry, soft commodity pricing, as well as permitting and regulatory issues. He also addressed the health of SME. Membership is relatively flat and publication sales are dropping. These are indicators of the challenges faced by the industry. SME has an operating surplus this year, has finished paying off debt and remains healthy. This year marked a successful con-gressional fellowship, and OneMine.org continues to grow (CIM has joined). The education sustainability program is moving forward and will involve funding up to 12 Ph.D. fel-lowships and career development grants for new faculty. He also acknowledged the huge contribution that SME, includ-ing the C&E Division, makes to scholarships.

Gardner visit — Steve Gardner, 2015 president-elect, also addressed the group. He intends to continue ongoing initiatives, including education sustainability, raising the status of health and safety within SME, and mining and sus-tainability. He acknowledged two concerns from the mem-bership: public perceptions of mining and perceived discon-

nects between SME and the local SME sections. He has appointed an ad hoc committee to examine local section relationships. He intends to engage other mining groups in a unified strategy to improve public perception. There was a discussion with Dave Kanagy, SME executive director, about local section outreach. And there was a discussion with Kanagy, Gardner and Marsden about the Health & Safety Committee.

Contributions — Bandopadhyay moved that $2,500 be contributed the SME Foundation with the following distri-bution: $500 to the Minerals Education Coalition, $1,000 to the Professional Engineers Exam Committee and $1,000 to ABET. The motion was carried.

A contribution to the Ph.D./faculty development fund was tabled until the midyear meeting when more details are available. A motion by Bandopadhyay that $10,000 be contributed to establish an endowed scholarship fund in memory of Bise was carried. A request for $5,300 to refur-bish the coal room at the National Mining Hall of Fame and Museum was discussed. Brune offered to collaborate with them in upgrading the display and contributing edu-cational content. A motion by Tadolini that $5,300 be do-nated to the effort was approved.

AdjournmentThe meeting was adjourned at 11:30 am by LaBranche.

The next general meeting will be on Sept. 10, 2015 in Lex-ington, KY.

WAAIME NewsExecutive Committee

Greetings to all WAAIME members. The 2015 annual meeting of WAAIME was held in Denver, CO and pro-

duced a number of decisions.

SME FoundationWith regard to the proposed merger with the SME Foun-

dation, the Executive Committee ultimately decided not to merge at this time. Responses from various sections were in favor of continuing as a division. Our thanks to SME and the SME Foundation for their truly interesting proposal and an option that could be revisited, if circumstances change.

PortfolioOur portfolio is now fully invested by UBS with an em-

phasis on producing cash to fund our various programs. It is a diversified portfolio to attempt to insulate it from the extremes of the market. As of February 2015, the WAAIME portfolio is worth in excess of $8.3 million.

Cajamarca Section The Cajamarca-Peru Section lost the majority of its

members due to the political unrest in that area of Peru. With the assistance of a number of companies and people in Peru, the remaining funds of the Cajamarca Section will be transferred to the Lima-Peru Section, which will continue to serve the students of Cajamarca. The Cajamarca Section will then be closed. Our thanks to all who assisted in getting this accomplished.

Founders Award WAAIME’s first Founders Award was presented to

Bonnie McMorris of the Utah-Northern Section. Bonnie is a longtime and actively involved member of that section and a great supporter of the national board of directors in past years. She received a beautiful gold pendant designed and crafted by a member of the Mexico-DF Section, and the Utah-Northern Section received a $500 check for its pro-grams. Congratulations to Bonnie. Nominations for the 2016 Founders Award are now open, and the Executive Commit-tee hopes that many sections will submit nominees for us to consider. Reasonable lodging and transportation reimburse-ment will be provided for the recipient.

Executive CommitteeThe WAAIME Executive Committee decided not to

rotate or change personnel for the 2015-2016 term — Jean Davin, executive committee chair and eastern representative; Cecilia Martinez, international representative and Barbara Filas, western representative — will continue to serve.

Key SME-WAAIME liaisons left SME employment and WAAIME was concerned about the lack of historical knowl-edge. The committee, therefore, felt it prudent to retain the current structure and to also review this issue further. The Executive Committee has decided to revisit the WAAIME

operating practices and bylaws and submit revisions to the SME Board of Directors. As of March 2015, we have been assigned a new set of SME liaisons. Genny Homyack will as-sume Mary O’Shea’s responsibilities, and Kaley Hollarn will assume Tessa Baxter’s. Our thanks to AnnMarie Kochevar, Lorie Laessig and John Hayden for their excellent assistance in the interim.

Outreach fundAn ad hoc committee was formed to create a WAAIME

program to fund local section outreach activities. Proposals will be discussed at the midyear meeting. The Iris Whinnen-Owen silent auction raised more than $2,000 at the 2015 annual meeting. The auction’s three-year total is more than $5,000 and will also be used to help fund local outreach pro-grams.

AIME funds AIME decided not to fund any proposal in the 2014-2015

fiscal year. WAAIME had submitted a scholarship proposal last year to AIME.

Scholarships awardedThere were 124 scholarship applications considered by

WAAIME at the SME Annual Conference. Of those consid-ered, 14 were not funded for various reasons. The remaining scholarship grants totaled approximately $250,000 again this year. Additionally, the five international sections will receive a total of $60,000 to help fund their students this fiscal year. Many thanks to all the scholarship chairs and the interview-ers who assisted in making this another successful year.

Scholarship softwareFeedback on the new scholarship computer software

program was discussed at the meeting and also by an ad hoc committee. Recommendations were made to SME personnel for requested improvements. Additionally, the interviewer form developed for this year’s scholarship interviews re-ceived high marks from everyone. A few tweaks are planned for next year’s version.

ReceptionMore than 100 students and guests attended the

WAAIME reception during the SME Annual Conference. Please see the photos in the newsletter of many of our schol-arship recipients and guests who attended. Our thanks to all who shared in the evening.

100th anniversaryLastly, the 100th Anniversary Planning Committee met

during the Annual Conference and brain-stormed various ways to celebrate this truly fantastic accomplishment. It is proposed that WAAIME celebrate its 100th Anniversary during the 2017 SME Annual Con- (Continued on page 80)


WAAIME NewsMeeting Minutes

The WAAIME Executive Committee met on Feb. 15, 2015 in Denver, CO. Attendees included Executive

Committee members Jean Davin, eastern representative and chair, Cecilia Martinez, international representative; and Barbara Filas, western representative; WAAIME mem-bers Nina Bucheli, Winnell Burt, Kathryn Dew, Karen Jass, Eugenia Lomelin, Elisabeth Price and Iris Whinnen-Owen; UBS Financial Services representatives Tom Austin, Fred Alesandro and Ryan Smith; SME staff members Mike Hedges, deputy executive director, and Lorie Laessig.

Introductions and minutesChair Davin introduced all members present. The Sept.

20, 2014 minutes of the WAAIME Executive Committee meeting were approved.

Financial updateMike Hedges reported that for the fiscal year ended

Sept. 30, 2014, total administrative expenses were $53,688. Labor was $20,170, which was a little higher than normal, primarily due to the transition in investment firms from Hirtle Callaghan to UBS. Operating expenses of $33,518 in-cluded committee travel reimbursements, $10,129; printing, $6,647 and postage, $4,735, largely to produce the newslet-ters, the member directory and scholarship packets; audit and tax return expenses, $5,000; the annual meeting recep-tion, $4,127 and expenses associated with committee meet-ings, $1,706. Program revenue included investment income of $297,204, contributions of $9,965 and miscellaneous income of $1,637, which was from the silent auction held in February 2014.

Hedges reported that year-to-date total administrative expenses were $5,865. Labor costs included about $1,700 associated with the potential SME Foundation (SMEF) merger activity, which will be reclassified and paid by SME. The only other significant expense was $1,193 in postage costs, primarily for mailing scholarship packets to WAAIME sections. Program revenue included investment income of $144,676 and contributions of $1,645.

Davin requested the names of those who contributed to the WAAIME fund. Hedges will provide a report to Davin so that thank you notes can be sent.

The committee reviewed the spending guideline cal-culation for FY2015, which allows up to $407,362 in total spending. Expenditures include undergraduate and gradu-ate scholarships, scholarship grants to existing international sections, other program grants, and audit and administrative costs and fees for SME’s management of the WAAIME division.

UBS investment reportTom Austin, Fred Alesandro and Ryan Smith from UBS

Financial Services reported on all of the WAAIME invest-ments. They provided a comprehensive report on news-

worthy financial events of the past year, as well as a 2015 global economic outlook.

The UBS representatives gave a detailed review of each investment account in the portfolio, including a timeline of when funds were fully invested, mostly dur-ing the first quarter of 2014 but, in some cases, extending into October and November of 2014. They reviewed each account’s performance against its individualized compara-tive index. The WAAIME portfolio is a diversified, risk-adjusted portfolio with an emphasis on its fixed income components producing consistent dividends year after year. As currently constructed, the portfolio will provide a consistent cash flow of more than $232,000 each year. They used a chart to illustrate that diversified portfolios perform very consistently over time (4.2 percent in 2014 versus 3.8 percent for our portfolio, even though not fully invested in 2014), and that the various individual styles go in and out of favor over time.

Davin asked for recommendations on changes that could be made to increase the return on the WAAIME portfolio. Alesandro did not recommend dramatic changes to the WAAIME portfolio at this point, since it has not been a year since being fully invested.

WAAIME/SME Foundation potential mergerBarb Filas provided a presentation on the potential

merger of WAAIME with the SME Foundation. Filas’ pre-sentation included a comprehensive look at the structure of SME and SMEF and described the duties of the board of directors, board of trustees and the various committees. Filas also provided a comparison of SME, SMEF, their pro-grams and current financial status. Discussion was held as to the advantages and disadvantages of merging with the SME Foundation.

After the adjournment of this meeting, on Monday, Feb. 16, a motion was made to vote on the WAAIME/SMEF merger. A motion was made to not merge with the Founda-tion. Filas noted that if the WAAIME Executive Commit-tee could not decide unanimously to merge with SMEF, then the merger should not take place. It was approved that WAAIME would remain a nontechnical division of SME.

Cajamarca updateCecilia Martinez provided an update on the Cajamarca

Section. This section has been reconstituted and is now in the process of registering signatures so that its money can be accessed. Once the funds can be accessed, WAAIME will close the Cajamarca Section, and the money will be transferred to the Lima Section. The Lima Section will pay all expenses for this transaction and will continue to give support to the Universidad Nacional de Cajamarca. Minera Yanacocha has been paying the costs of recovering the money and exerting its influence in order to resolve this problem. The Cajamarca Section’s fund is approximately

WAAIME NewsMeeting Minutes

$54,000 plus 4,000 Peruvian soles (approximately $1,330).Susan Palomino has been invited to be a member of the

Lima Section board. She will prepare the program and cre-ate a system for scholarships for Cajamarca students, which may provide an opportunity for a student to study abroad for a master’s degree.

Martinez will provide a list of all those who were instru-mental in this endeavor and the WAAIMEs will send thank you notes to all.

Topics moved to respective meetingsThe scholarship review process will begin Feb. 16. There

are approximately 118 scholarships to review. Davin ex-plained that after the scholarship review program is com-plete, the group will critique the WizeHive scholarship pro-gram procedures. Positive reviews have been received on the interviewer procedure set up by Filas and Kathryn Dew. SME staff will assist with the scholarship review process.

The international sections’ student review was moved to the midyear meeting.

The 100th Anniversary meeting will be held on Feb. 18, 2015 at 9 am. Beth Price, Dew, Martinez and Julie Varichek will attend this meeting.

AwardsThe four WAAIME Founder’s Award medals were

received from Mexico at a cost of $320 each. Hedges pro-vided cash to reimburse Eugenia Lomelin for providing these medals. She will submit a receipt. Davin inquired as to the $2,000 check written in September 2014 to the Mexico-DF Section and deposited in the Mexico-Torreon Section’s account as normal. But the bank refused to cash the check. Hedges will investigate the status of the $2,000 check and reimburse the Mexico-Torreon’s bank account.

Attendees discussed providing a stipend for the Found-er’s Award recipient’s expenses. It was suggested that the WAAIME Executive Committee reimburse one night’s hotel stay, air fare and other transportation expenses up to $1,000. However, the award may be granted to an interna-tional member, requiring higher expenses. It was approved that the Executive Committee would approve reasonable transportation and lodging expenses for reimbursement. This reimbursement provision will be added to the Found-er’s Award guidelines and referred to the SME Board of Directors at the midyear meeting.

Leadership transition/proposed changes to operat-ing practices

The Executive Committee has been reviewing the cur-rent WAAIME Committee of SME operating practices and bylaws. Changes have occurred, and need to occur, since the operating practices were written in 2008. The Executive Committee will rewrite the WAAIME operating practices and bylaws, incorporate what is useful and refine them to anticipate growth and increased participation. Once complete, they will need to be approved by the SME Board of Directors. It was suggested that WAAIME col-laborate with the Women in Mining and the Women’s Min-

ing Coalition to facilitate growth in membership.

WAAIME donationsThe WAAIME yearly donation to the Colorado Min-

ing Association’s (CMA) summer program for teachers, All About Mining, was discussed. It is in the process of becom-ing a mostly online program. This year, CMA has asked for a contribution to the National Mining Hall of Fame and Museum in Leadville, CO. Davin also discussed WAAIME’s $5,000 annual gift to the Minerals Education Coalition (MEC). Davin suggested that in lieu of donating to the MEC, WAAIME should buy $5,000 worth of MEC materi-als and donate them to WAAIME sections, as well as to uni-versity student sections, for outreach to (K-12) schools.

Karen Jass suggested creating a WAAIME grant pro-gram. WAAIME would solicit applications for grants from WAAIME sections, SME local sections and SME student chapters that include an estimate of need. Grants would be awarded based on need. Recipients would provide WAAIME with a detailed accounting of how the grant was used. Filas suggested that Pam Wilkinson be contacted for further information on the type of materials available for purchase from MEC. Filas, Mary O’Shea and Jass will form a committee to create a WAAIME program to fund local outreach programs.

WAAIME Executive CommitteeDuring a conference call in December 2014, it was decid-

ed that Davin would serve another term as WAAIME chair to maintain continuity due to the changes in the SME staff liaison, and the relative newness of the remaining members of the Executive Committee. The decision was unanimously affirmed. This continuity issue will be paramount in the pro-posed changes to the operating practices for review by the Executive Committee. The WAAIME Executive Committee will remain the same for the 2015-2016 fiscal year.

Silent auctionThe Iris Whinnen-Owen Silent Auction preliminary

totals are more than $2,000. The Silent Auction fund total is now more than $5,000. Discussion was held as to whether the money will go directly to the sections or be distributed through the program being developed for local section ap-plicants and student sections.

SME-WAAIME websiteThe WAAIME section of the SME website needs to

be updated. Normal procedures at SME that pertain to the WAAIME division have changed due to the assignment of new WAAIME liaisons. This issue will be reviewed at the midyear meeting.

AIME grant proposalNo information had been received on the WAAIME

proposal for a joint AIME-WAAIME $15,000 scholarship for students from the four member societies.

The next WAAIME Executive Committee meeting is scheduled for Sept. 10-12, 2015 in Lexington, KY. n

Elizabeth (Betty) Dunlop Ensign died Oct. 11, 2014 after a brief battle with pancreatic cancer. She was born in Sanford, NC on Dec. 15, 1925 to Willard and Aileen Dunlop. She grew up on the Pinehurst dairy farm started by her grandfa-

ther J. Sheldon Dunlop.Ensign is survived by her husband Chester O. Ensign

Jr., to whom she was married for more than 64 years, two sons, Chester and Steven, two granddaughters and a great-grandson.

As the wife of a mining executive, Ensign traveled the world with her husband. She lived in Bartow, FL, St. Louis, MO, Westport, CT and White Pine, MI. She served two terms as president of WAAIME, June 1971 to June 1972 and March 1975 to March 1978.

Ensign was an expert sailor. For many years, she was a member of the Saugatuck Harbor Yacht Club in Westport, CT and the Apostle Island Yacht Club in Bayfield, WI. She cruised and raced the waters of the Great Lakes, Long Island Sound, the New England coastline and the Gulf of Mexico. After her husband retired, the Ensigns moved to Fort Myers, FL. They returned to Pinehurst in 2006, where they made many friends. n

The WAAIME Utah-Northern section was honored to have Lisa Gentile, the new dean of the School of Arts

and Sciences at Westminster College, and Tiffany Rivera, the newest addition to Westminster’s Geology Depart-

Guests at the UT-N section luncheon included (l-r) Lisa Gentile, Tiffany Rivera, Nick Yelter and Allison Woolsey.

ment, as its guests at the November meeting held at the Alta Club. Other guests from Westminster College were the student Geology Club’s president, Nick Yelter, and vice president Allison Woolsey. Students from the Uni-versity of Utah’s Department of Mining Engineering also attended the luncheon and meeting — Crystal Darger, Avyette Richardson, Katelyn Frary and Samantha Davis.

Westminster College has finally received official ap-proval of its new Geology Department, so some of their students will be applying for WAAIME scholarships for the coming year, just as the University of Utah students have done in previous years.

It was a delight for our ladies to be able to meet and visit with Gentile and Rivera, and to see students from both schools have such an enjoyable time while attending our meeting. Even though they attended different schools, they were all interested in the same fields of study, so some of the Utah students exchanged information with the Westminster students about applying for WAAIME scholarships. n

The Utah-Coal Section of WAAIME held its 20th Annu-al Coal Country Classic golf fundraiser on Sept. 6, 2014.

The fundraiser netted $15,103 and, with the added raffle donations of $2,807, a grand total of $18,000 was raised for scholarships and outreach to schools in Carbon and Emery counties.

On a beautiful sunny day, 33 teams (four-person scram-ble) got off to an early start. They were treated to a hot breakfast, 18 holes of golf, complimentary beverages, golf shirts, a lunch buffet and an awards ceremony. All of which were donated by our wonderful sponsors. Of course, all the section members were on hand to sell raffle tickets. No one gets away without buying tickets, and all teams receive a prize. This year Nick Nielsen, a former WAAIME scholar-ship student, played in the tournament. He now works at the Skyline Mine near Price, UT. He told us he would have had to drop out of school if it weren’t for the scholarships he received from WAAIME. And his wife Beth has become a section member.

It seems like just yesterday that the Coal Country Classic golf fundraiser began. Yet the fundraiser just cel-ebrated its 20th year. Ellis Pierce of Pierce Oil/Golden

West Industries and the WAAIMEs have been partners in this event from the beginning. Ellis came up with the idea and the Utah-Coal Section jumped in feet first. We can al-ways count on companies and individuals from all over the United States to graciously give to our fundraiser. With the proceeds, the section has given out thousands of dollars in academic scholarships to students pursuing careers in ener-gy-related fields. The section also gives books, educational materials and fields trips to all of the schools and libraries in Carbon County and Emery County. What a wonderful event this has been for everyone involved.

I cannot finish without giving a heart-filled thanks to the Coal Country Classic committee: Ellis Pierce, Jim Ku-low, Tony Martines, Charlie Philips, Robert Richins and WAAIME UT-Coal Section members. This is a great team of people who never tire of giving, and they have made our section respected in the educational world. To all the many sponsors and players who dig deep into their pockets each year, we thank you.

Carbon School District Science FairOn Jan.23, 2015, the Utah-Coal Section presented cash

awards in the junior and senior divisions of the Carbon School District Science Fair. The judges sought out the best projects in the fields of energy, metallurgy, geology, earth science, material science and engineering.

The winners in the senior division were Mersedez Clif-ford, $150, and Luke Hansen, $100. Junior Division winners were Emily Jesperson, $150 and Kade Allen, $100. The sec-tion would like to thank all of the students who took the time to enter the science fair. n

WAAIME News

The Missouri-Rolla Section, with the assistance of a national WAAIME

grant, helped five rural schools with their science needs this year. These schools were appreciative of the WAAIME grants because they are often overlooked, and their needs are great. The Dent-Phelps R3 school purchased 10 hot plates to perform a variety of experiments. Lick-ing High School ordered a stream-table kit, three different rock collections, a scale hardness collection and a physical properties of minerals collection. The Salem Junior High School took a field trip to the Doe Run Mine Co., which would not have been possible without the grant from WAAIME. The St. James Junior High School ordered fossil kits and earth science lessons for interactive white boards, rock detective bucket kits, and a Pangaea cutter and placemat set. The Maries County R2 Middle School purchased a water barometer, a working anemometer, a modeling faults activity kit and a weather center.

During the summer of 2014, the Missouri-Rolla chapter sponsored a local girl’s participation in It’s A Girl Thing summer camp at the Missouri University of Science and Technology (Missouri S&T). The camp is open to seventh and eighth grade girls, who explore STEM careers through group projects and design competitions.

In addition to the activities benefitting the local primary and second-ary schools, the Missouri-Rolla chapter honored Missouri S&T students with a scholarship luncheon in October 2014. We are grateful once again to Matthew O’Keefe for sponsoring our luncheon at the Havener Center on the Missouri S&T campus.

Sadly this past year we lost two members of our local chapter, Shirley Day and our treasurer Jane O’Keefe. In memory of Shirley, a donation was made to the Expanding your Horizons in Science, Engineering, Math-ematics and Technology conference for girls at Missouri S&T on Nov. 7, 2014. In memory of Jane, the chapter donated money to the science pro-gram at St. Patrick’s school, a local school that was dear to her. n

The Drift of Things


Mining,explorationin2014

Minerals production during 2014 remained fundamental

to the U.S. economy, contributing an estimated $17.4 billion to the nation’s gross domestic product, according to the U.S. Geological Survey (USGS). This occurred at several levels including mining, processing and manufacturing of finished products.

The agency’s National Minerals Information Center’s assessment of the domestic mining industry’s perfor-mance for 2014 begins on page 39 of

this issue. Before that, though, is one of the most comprehensive reviews written of global explo-ration activity last year, also written by USGS experts, beginning on page 16.

In its analysis, the USGS reports that the estimated value of nonfuel mineral raw materials last year amounted to $75 billion, up 3.5 percent from 2013’s $75 billion. That includes metals and industrial minerals production. Raw materi-als produced in the United States, along with recycled materials, were used to process mineral materials valued at $697 billion. These materials were, in turn, consumed by downstream indus-tries, which resulted in an added value of about $7.53 trillion, the USGS estimates.

The value of production from U.S. metals mines during 2014 was about $31.5 billion, down slightly from 2013. The major contributors were copper (32 percent), gold (27 percent), iron ore (16 percent), zinc (6 percent), lead (3 percent) and silver (2 percent).

Industrial minerals production values during 2014 increased by 7.5 percent to $46.1 billion. This accounted for 59 percent of the value of all nonfuel minerals production last year. The USGS reports that more than 6,500 companies, producing from more than 12,000 mines, quar-ries and processing facilities, contributed to this value.

The graphic on page 46 is a telling figure. It shows that the United States is 100-percent im-port-dependent on 19 mineral commodities and more than 50 percent import-dependent on 43 mineral commodities. In 1973, when this infor-mation was first reported, the United States was 100 percent import-dependent on six mineral

commodities and 50 percent import-dependent on another 20.

Meanwhile, the total estimated worldwide budget allocation for nonferrrous mineral explo-ration was about $10.7 billion, down 24 percent from 2013, which itself was down from 2012, the USGS reports. This was due to continued mar-ket instability and reduced available funding for exploration work, particularly among junior ex-ploration companies.

The amounted budgeted for gold explora-tion last year was down by 31 percent from 2013 to $4.6 billion. Base metal exploration budgets decreased by 21 percent to $3.7 billion. Copper exploration accounted for about 70 percent of that amount.

On a regional basis, Latin America continued to be the leading area for budgeted exploration dollars. That was followed by Africa, Canada, Australia, the United States and the Pacific re-gion. China and Russia accounted for about 56 percent of the exploration dollars budgeted in the Rest of World region.

SMEaddressesarsenic in mining

The Government and Public Affairs Com-mittee of SME recently issued its latest technical briefing —The Role of Arsenic in the Mining Industry. This report follows an earlier briefing that deals with cyanide use in the industry.

The general public has a real or perceived fear of anything attached to the words “arsenic” and “cyanide.” These technical briefings, written by industry experts, are attempts to allay some of those fears by presenting factual environmental and health and safety information concerning their use.

This report on arsenic explains what arsenic is and how it occurs in nature. It also describes how it is used in the mining industry as well as what the industry does to prevent arsenic pollu-tion. The briefing also lists the amount of arsenic produced each year from around the world, and how it is used in various products.

The technical briefing on arsenic can be found on the Mining Engineering website, www.miningengineeringmagazine.com. Click on On-line Exclusives. Other technical briefings can be found on the SME website, www.smenet.org, click on Government and Public Affairs. n

Graus Chemicals, LLCwww.grauschemicals.comREMOTOX®- A Strong Precipitant for Removing Heavy Metals from Process Wastewater. REMOTOX is a calcium polysulfide based liquid designed to form a dense, filterable precipitate when treating most regu-lated heavy metals. The product is effective even when treating strongly chelated and/or complexed metals without employing other pretreatment options. Chrome 6 is easily removed and does not need to be reduced prior to precipitation. PRODUCT ADVANTAGES: ->Selective metal precipitation allowing for recovery of valuable metals. ->High reactivity with heavy metal ions and extremely low solubility of resulting metal sulfides over a wide pH range, producing lower effluent con-centrations. ->Dissolved calcium ions form a coagulant aid (Ca(OH)2). ->Better settling and dewatering aspects of the metal sulfides, resulting in a more compact solid sludge. -> Not DOT regulated. -> Relatively low cost compared to alternative treatment chemicals. REMO-

TOX is available in drums, totes and in tank truckloads. For additional information, complimentary samples or pricing, please contact us at 623.328.5175 or by email at [email protected].

Optechwww.optech.comMine operators across the globe rely on Optech sensors to provide rapid yet accurate 3D surveys for mapping, volume estimates, and safety analysis. The compact and rugged Optech CMS Cavity Monitor-ing System uses a rotating sensor head with sealed optics on an extensible shaft to produce precise and detailed engineering models of hazardous areas for blast review, stope analysis, and backfill execution and planning. The latest CMS V500 model is a wire-less single-unit system with no bulky power supply or cables that introduces an extended field of view, in-field backsighting and resectioning, cart-based mobility, and a unique-in-the-market integrated camera that collects still and video imagery. For open-pit mines, the tripod-mounted Optech ILRIS Terrestrial Laser Scanner maintains high accuracy at ranges up to 3 km to safely survey dangerous or inaccessible areas, while the Optech Lynx Mobile Mapper® operates from a moving vehicle to map in hours what would normally take weeks. Operators can also reach inaccessible ar-eas using the Optech XR6 UAV, a lightweight camera-equipped hexacopter that integrates with the ILRIS software workflow for rapid multi-sensor surveying, or take to the skies themselves with the aircraft-mounted Optech Orion and Galaxy lidar systems for large-scale mapping.
