This document contains forward-looking statements under Canadian securities legislation. Forward-looking statements include, but are not limited

to, statements with respect to the development potential and timetable of the Rosita project; the timing and amount of estimated future

development and exploration; costs of future activities; capital and operating expenditures; success of exploration activities; government regulation

of mining operations; and environmental risks. Generally, forward-looking statements can be identified by the use of forward-looking terminology

such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not

anticipate”, or “believes”, or variations of such words and phrases or statements that certain actions, events or results “may”, “could”, “would”,

“might” or “will be taken”, “occur” or “be achieved”. Forward-looking statements are based on the opinions and estimates of management as of the

date such statements are made. Forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may

cause the actual results, level of activity, performance or achievements of the Company to be materially different from those expressed or implied

by such forward-looking statements, including but not limited to risks related to: timing and availability of external financing on acceptable terms;

unexpected events and delays during construction, expansion and start-up; variations in ore grade and recovery rates; receipt and revocation of

government approvals; actual results of exploration and mining activities; changes in project parameters as plans continue to be refined; future

prices of metals; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining

industry. Although management of the Company has attempted to identify important factors that could cause actual results to differ materially from

those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There

can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those

anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. The Company does not

undertake to update any forward-looking statements except in accordance with applicable securities laws.

The technical and scientific information included herein has been reviewed and approved by Joseph Arengi, M.Sc., P.Geo , President and CEO of

the Company, and a qualified person under National Instrument 43-101 of the Canadian Securities Administrators.

Notes on Mineral Resource Estimation

1. See Data in NI 43-101 Technical Report entitled “Technical Report on Mineral Resource Estimate of the Rosita Stockpiles” dated June 22, 2012 and filed on SEDAR.

2. The mineral resource estimate base case is reported at a 0.15% copper equivalent cut-off grade; this cut-off incorporates consideration of mining and processing cost,

recoveries, commodity prices and selling cost.

3. The mineral resource estimate is reported on an undiluted basis.

4. The mineral resource estimate assumes a long term copper price of US$2.90/lb, a gold price of US$1,200/oz and a silver price of US$24/oz.

5. Rounding as required by NI 43-101 reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content.

6. Tonnage and grade measurements are in metric units. Contained gold and silver ounces are reported as troy ounces, contained copper pounds as imperial pounds.

7. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by

environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

8. The quantity and grade of reported inferred mineral resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred

mineral resources as indicated or measured mineral resources and it is uncertain if further exploration will result in upgrading them to indicated or measured mineral

resources.

Historic Tonnage and Copper

1. See Data in NI 43-101 Technical Report entitled “Technical Report on Mineral Resource Estimate of the Rosita Stockpiles” dated June 22, 2012 and filed on SEDA

2. Disclosure of Historical Estimates.

3. Despite section 2, an issuer may disclose an historical estimate, using the original terminology, if the disclosure: (a) identifies the source and date of the historical estimate, including any existing technical report; (b) comments on the relevance and

reliability of the historical estimate; (c) to the extent known, provides the key assumptions, parameters, and methods used to prepare the historical estimate; (d) states whether the historical estimate uses categories other than the ones set out in sections

1.2 and 1.3 of 43-101 (i.e. inferred, indicated, etc.) and, if so, includes an explanation of the differences; (e) includes any more recent estimates or data available to the issuer; (f) comments on what work needs to be done to upgrade or verify the historical

estimate as current mineral resources or mineral reserves; and; (g) states with equal prominence that; (i) a qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves; and; (ii) the issuer

is not treating the historical estimate as current mineral resources or mineral reserves. or mineral reserves.

Reasons to Invest

Past producing project with

significant economic

potential

• Previously a high grade, open-pit

mine with historic production of

245 million lbs Cu, 160,000 oz

Au and 2.61 million oz Ag

• Potential for project with

excellent economics at current

copper price levels

• Proximity to emerging and active

mining districts

Robust resource base with

exploration upside

• Stockpiles include a NI 43-101

compliant inferred resource of 8

million tonnes containing 108.5

million lbs Cu, 118,500 oz Au and

2.4 million oz Ag (1.01% Cu Eq.

grade1)2,3

• Excellent drill and trenching

results illustrate the potential to

establish a significant high grade

resource

Well positioned in a stable

and emerging mining district

with strong management

• Located in the prolific Mining

Triangle of northeast Nicaragua,

host to several significant copper

and gold porphyry deposits

• Stable, pro-mining government

with supportive mining laws and

a reasonable mining tax regime

• Highly experienced management

team with strong Central

American Focus

1. Assumes a long term copper price of US$2.90/lb, gold price of US$1,200/oz and silver price of US$24/oz.

2. See Data in NI 43-101 Technical Report entitled “Technical Report on Mineral Resource Estimate of the Rosita Stockpiles” dated June 22, 2012 and filed on SEDAR.

3. As reported in the news release issued by Alder on May 9, 2012, the inferred resource estimate totals 7.95 mt, at an average grade of 0.62% Cu, 0.46 g/t Au and 9.2 g/t Ag

with an overall copper equivalent grade of 1.01%. The inferred mineral resource contains 108 million pounds of Cu, 118,500 ounces of Au and 2.35 million ounces of Ag.
