Cautionary & Forward Looking Information
2
This presentation includes certain statements that may be deemed "forward-looking statements". All statements in this presentation, other than statements ofhistorical facts, that address exploration drilling, exploitation activities and events or developments that the Company expects are forward-looking statements.Although the Company believes the expectations expressed in its forward-looking statements are based on reasonable assumptions, such statements shouldnot be in any way construed as guarantees of the ultimate size, quality or commercial feasibility of the Pebble Project or of the Company's future performanceor the outcome of litigation. Assumptions used by the Company to develop forward-looking statements include the following: the Pebble Project will obtain allrequired environmental and other permits and all land use and other licenses, studies and development of the Pebble Project will continue to be positive, andno geological or technical problems will occur. The likelihood of future mining at the Pebble Project is subject to a large number of risks and will requireachievement of a number of technical, economic and legal objectives, including obtaining necessary mining and construction permits, approvals, licensesand title on a timely basis, delays due to third party opposition, changes in government policies regarding mining and natural resource exploration andexploitation, the final outcome of any litigation, completion of pre-feasibility and final feasibility studies, preparation of all necessary engineering forunderground workings and processing facilities as well as receipt of significant additional financing to fund these objectives as well as funding mineconstruction. Such funding may not be available to the Company on acceptable terms or on any terms at all. There is no known ore at the Pebble Project andthere is no assurance that the mineralization at the Pebble Project will ever be classified as ore. The need for compliance with extensive environmental andsocio-economic rules and practices and the requirement for the Company to obtain government permitting can cause a delay or even abandonment of amineral project. The Company is also subject to the specific risks inherent in the mining business as well as general economic and business conditions. Formore information on the Company, Investors should review the Company's annual Form 40-F filing with the United States Securities and ExchangeCommission and its home jurisdiction filings that are available at www.sedar.com.
This presentation also uses the terms “measured resources”, "indicated resources" and "inferred resources". Although these terms are recognized andrequired by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), the U.S. Securities and ExchangeCommission does not recognize them. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever beconverted into reserves. In addition, "inferred resources" have a great amount of uncertainty as to their existence, and economic and legal feasibility. Itcannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates ofInferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for Preliminary Assessment as definedunder 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
The technical information contained in this presentation has been reviewed and approved by qualified persons which are not independent of NorthernDynasty. Information on geology, drilling and exploration potential has been reviewed by James Lang, PGeo., information on Mineral Resources by DavidGaunt, PGeo., and information related to engineering and metallurgy by Stephen Hodgson, PEng.

Alaska State Constitution (1949)“It is the Policy of the State of Alaska to encourage…the development of its resources by making them available for maximum use consistent with the public interest”
Cook Inlet Land Exchange (1974)• Three way land swap involving Federal
government, State of Alaska and Cook Inlet Regional Inc. (CIRI)
• State of Alaska accepted land including what is now Pebble, explicitly for its mineral prospectivity without restriction
Bristol Bay Area Plan (2005)“The general resource management intent for the Pebble Copper Area is to accommodate mineral exploration and development…”
The Alaska Permanent Fund• Resource development is important
EPA pre-emptive Section 404(c) Process –Unauthorized, Unprecedented, Unilateral, Unfounded
• On February 28, 2014 EPA announced initiation of regulatory process under Section 404(c) of the Clean Water Act (“CWA”) to decide whether to take pre-emptive action to stop mining activity in the Bristol Bay region
• This despite the fact that: – no mine permit application has been submitted
– the CWA makes clear that the Army Corps of Engineers is the lead federal agency
– the State of Alaska has a central regulatory role
– no harm comes to the environment if EPA follows NEPA process
• Internal EPA memo acknowledges that proactive action to veto or restrict development at Pebble has “never been done before in the history of the CWA”
8
Pebble – 2014 InitiativesStatutory Authority Litigation
• PLP filed an action in Federal District Court in Alaska alleging that EPA does not have statutory authority to seek a pre-emptive veto
• The State of Alaska and the Alaska Peninsula Corporation joined the litigation as co-plaintiffs
• Amicus briefs submitted to court by an array of resource industry players, including:– American Petroleum Institute – National Mining Association– Alaska Miners Association– Alaska Oil and Gas Association– Alaska Chamber– Alaska Support Industry Alliance– Council of Alaska Producers
• The Court has dismissed PLP’s case on procedural grounds only• The dismissal has been appealed to the 9th Circuit; a decision is expected soon
9
Pebble – 2014 InitiativesFederal Advisory Committee Act Litigation
• Federal Advisory Committee Act – Enacted by Congress to prevent closed-door, back-room policy making
• Based on FOIA disclosures, Pebble’s FACA lawsuit alleges that EPA violated Federal law– Federal Advisory Committee’s (FAC) were treated by EPA as an auxiliary EPA
– FAC’s played a leadership role in unprecedented EPA pre-emptive veto scheme
• PLP was granted a Preliminary Injunction (PI) in Federal court in Alaska against EPA – Prerequisite for court to grant PI is that the claimant have “a likelihood of
success on the merits of the claim”
– First time EPA has been stopped since BBA process began
• 2015 – A fact-based trial
10
Pebble – 2014 InitiativesInspector General Investigation of EPA Conduct
• Northern Dynasty, the AK Attorney General, Senator Murkowski and Congressman Young requested that the EPA Inspector General (IG) open an investigation into concerns regarding EPA bias and collusion with environmental activists in the preparation of the Bristol Bay Assessment (BBA)
• After careful consideration the IG opened a preliminary investigation. The IG has converted its original preliminary investigation into a comprehensive investigation and plans to issue a formal report
• The IG has complete access to EPA email servers to seek relevant documents beyond those we have been given by EPA

Bristol Bay Salmon – The Real StoryThe Fishery is Not Threatened
12
• Bristol Bay Watershed• 41,900 sq. mi• 9 discrete river systems
• Kvichak & Nushagak-Mulchatna• 23,000 sq. mi• ~20% of Bristol Bay sockeye production
• Pebble Project Area• ~16 sq. mi (1/25th of 1% of 41,900 sq. mi)• 2 of 9 watersheds
• N/S Fork Koktuli & Upper Talarik• 400 sq. mi in area of deposit• <0.5%* of Bristol Bay sockeye production
* 0.5% will be conserved and enhanced
Pebble: Answering Important Questions with Science What About the Fish Habitat and Fish?
• Extensive hydrological studies undertaken over 10 years – PLP estimates that 5 times more surplus water will be available for treatment and release to mitigate potential downstream effects on aquatic habitat than the Bristol Bay Assessment (“BBA”) predicts
– Pebble’s PHABSIM* model is built upon some 10 years of site-specific stream flow monitoring and aquatic habitat surveys in the 3 streams surrounding the Pebble deposit. It can predict habitat availability for 4 species of salmon and 3 species of resident fish in 100’s of catalogued stream reaches at different times of the year and for different life stages
• $150 million invested in Environmental Baseline Studies - Approximately $75M is on fisheries and water related research
13
CONCLUSION: The BBA erroneously leaves readers with the assumption that all aquatic habitat is equal – empirically NOT correct!
Pebble: Answering Important Questions with Science What About the Fish Habitat and Fish?
• EPA stream length estimates in the BBA are a very small portion of all streams in the watershed according to USGS data
• Scientifically proven mitigation opportunities provide Pebble ample opportunity to create more habitat in local watersheds than will be affected by the mine development– Pebble will enhance aquatic habitat,
availability and fish production

* The Physical Habitat Simulation (“PHABSIM”) model, originally developed more than 30 years ago by the U.S. Geological Survey and the U.S Fish and Wildlife Service, is one of the most scientifically advanced and widely accepted methodologies for determining aquatic habitat versus stream flow relationships.
CONCLUSIONS: • The BBA projected impacts on downstream water flows and fish habitat are
flawed and exaggerated• The best science will allow Pebble to build the best mine while conserving
BB fisheries. Absolutely no net loss to the fishery!
Pebble: Answering Important Questions with ScienceWhat About the Water?
15
• Robust engineered water management system
– All contact water collected and stored in SSF for re-use and release
– Highly-engineered seepage management, collection and monitoring systems
• State of the art water treatment & conditioning
• Strategic surplus water releases under permit– Scientifically proven habitat modeling
(PHABSIM) to forecast flow habitat effects – Considers 5 salmon and 3 species of
freshwater fish
• Pebble will maintain downstream water quality and flows to safeguard fish, wildlife and communities
WATER MANAGEMENT KEY PRINCIPLES:1. Water Management Boundary
Water will be restricted from entering the mine area by diverting it to nearby creeks and streams
2. Sand Storage Facility (SSF)Water collected in the mine area will be pumped to the SSF for storage, treatment and re-use
3. Water Treatment PlantWater from the SSF will be treated to meet stringent water quality standards before being released to the environment
4. Strategic Water ReleasesSurplus water will be strategically released into nearby creeks and streams to support fish habitat productivity
Pebble: Answering Important Questions with Science What About Seismicity?
• Engineered design criteria for Pebble SSF and other facilities are extremely conservative
• SSF design earthquake: – Various earthquake scenarios studied at locations
throughout region
– Lake Clark extension of Castle Mountain fault (inactive for 10,000+ years)
– Design assumes fault runs 10+ miles closer to Pebble than USGS estimates
– Design incorporates maximum estimated 7.5Mwmagnitude earthquake caused by rupture along entire length of inactive fault
• Modern SSF dams operate in regions with higher seismic risk than Pebble
– Fort Knox – Alaska – 7.9Mw earthquake in 2002
– Los Tortolas & 3 others – Chile – 8.8Mwearthquake in 2010
• All project facilities engineered to withstand Maximum Credible Earthquake scenarios associated with the region
16
CONCLUSION: Pebble will be designed to withstand seismic events larger than could have occurred over the last 10,000+ years and to more stringent criteria than regulations require.
Pebble: Answering Important Questions with Science What About the Sand Storage Facility?
17
OVERALL PRINCIPLES:• Three highly engineered embankments to provide safe, permanent storage of
1.8 billion tons of sand – Conservatively designed to withstand maximum forecast flood, storm, seismic events – Strict regulatory oversight and regular inspections by Alaska Dam Safety Program
• Conventional porphyry deposit water/solid composition – PAG sand (~10%) to be stored sub-aqueously and encapsulated in sand mass– SSF water at similar porphyry deposits support healthy fish populations
Modified Centerline Design
Pebble: The Path to a Record of DecisionNEPA and 404 Permit Process
• For a project like Pebble once an application has been filed:– Scoping – ½ year– Prepare Draft EIS – 1-1½ years– Public Comments – ½ - 1 year– Final EIS/ROD – 1 year– Total = 3 – 4 years
• History of the 404c Veto – 13 times in 41 years, but….• No 404 veto ever for a hard rock mine
18
• Our View:– EPA will not succeed in imposing a preemptive 404c veto or
development restrictions
– Pebble will get a 404 permit

Pebble Project – National Economic Impact Study1
Pebble can be Economically Very Significant
• Nationally– 15,000 jobs – $2.7 billion to US GDP annually– Increase US copper production by 20% over decades
of production
• In Alaska– Some 3,000 high-wage jobs – $109,500 average annual salary for mine workers –
more than double the state average– More than $1 billion in annual operating expenses– Pebble-related economic activity in Alaska will boost
the state's GDP by more than 3% over 2011 levels
• Pebble will literally transform the regional economy in Bristol Bay
– Secure, high-paying jobs – Of 5,394 working-age residents, just 63% worked in
2011 and only 35% were employed throughout the year– Increase Lake and Peninsula Borough tax base by a
staggering 600% annually over 2013 levels– Potential for affordable power for Southwest Alaska
1 The IHS report is intended to provide information about general economic effects/contribution of a development at Pebble to Alaska and the USA. The report should not be used to evaluate the Pebble Project’s impact on Northern Dynasty.

Environmental Baseline Document (EBD) – January 2012Scientific Integrity – Foundation for Successful Permitting
• State/Federal permitting requires scientific rigor
• Pebble environmental science – unprecedented scope/rigor
– $150 million spent on intensive multi-disciplinary studies over 9 years – 27,000 pages
– Data collection and other preparatory work ongoing– Integrity of work unassailable – World class 3rd party
scientists
• Empirical knowledge used to:– Characterize local environmental conditions– Provide unique guidance to optimize engineering design– Assess residual effects and inform mitigation measures– Establish a database for long-term project monitoring– Facilitate effective permitting – Counter ill-informed negative rhetoric
• Conclusions:– We have the science to build and operate a safe mine– Fisheries and mines can & do co-exist
36
Pebble Limited Partnership Approach –Responsible Mineral Development
• Environmentally driven design – Engineers and Scientists collaborate on optimal design• Avoid, minimize, mitigate and compensate• EBD science informs the project impacts which in turn inform mitigation response
and design• Mitigation possibilities include:
– In-stream habitat improvement – Improves existing and/or creates new habitat– “Off channel” habitat improvement – Creates new habitat– Water discharge – Project will have stringent water quality standards. Pebble site has
excess water. Depending on water usage, flow at Pebble will be distributed spatially and temporarily to maximize downstream fish habitat• Habitat suitability modeling• Very helpful during periods of natural water flow reduction
• Wetlands – “in kind” and “mitigation banks”• Exceptional commitment to the environment – Great neighbor• Conclusion – No net loss of any fishery – AND enhancement possibilities abound
– Fisheries and mining do co-exist around the world

Salmon Mitigation/Enhancement Opportunities
• Numerous Pebble/Bristol Bay streams not producing fish at full potential due to natural constraints:
– beaver dams & other barriers– dewatered & relic channels– low habitat complexity– limiting water quality– poor seeding due to low escapement
• Significant opportunities exist to apply proven techniques to remove constraints & enhance fish production:
– agency friendly– proven success with +50 years of fish habitat mitigation
track record– typically low technology measures– cost-effective
• Strategic surplus water releases using PHABSIM*

Hard Rock Mining & Salmon Do Co-Exist Fraser River Basin, BC*
• Fraser River basin a close analogue to Bristol Bay basin
• Empirical evidence shows mining activity over last 50 years had:− No negative effect on salmon
populations
− No negative effect on commercial salmon fishery
− No large scale effects on salmon habitat
− No relationship to salmon price
Correlation, yes. Scientifically proven cause and effect, no!But that is exactly the point.

5.94 Billion Tonnes Measured & Indicated4.84 Billion Tonnes Inferred
The estimate was prepared for the Pebble Partnership. David Gaunt, PGeo, a qualified person as defined under 43-101 who is not independent of Northern Dynasty, is responsible for the 2010 estimate.
Copper equivalent calculations used metal prices of US$1.85/lb for copper, US$902/oz for gold and US$12.50/lb for molybdenum, and metallurgical recoveries of 85% for copper 69.6% for gold, and 77.8% for molybdenum in the Pebble West area and 89.3% for copper, 76.8% for gold, 83.7% for molybdenum in the Pebble East area. Revenue is calculated for each metal based on grades, recoveries and selected metal prices: accumulated revenues are then divided by the revenue of 1% copper. Recoveries for gold and molybdenum are normalized to the copper recovery as shown below:CuEQ (Pebble West) = Cu % + (Au g/t x 69.6%/85% x 29.00/40.79) + (Mo % x 77.8%/85% x 275.58/40.79)CuEQ (Pebble East) = Cu% + (Au g/t x 76.8%/89.3% x 29.00/40.79) + (Mo % x 83.7%/89.3% x 275.58/40.79)
By prescribed definition, “Mineral Resources” do not have demonstrated economic viability. An Inferred Mineral Resource is that part of a mineral resource for which quantity and grade can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The mineral resources fall within a volume or shell defined by long-term metal price estimates of US$2.50/lb for copper, US$900/oz for gold and US$25/lb for molybdenum.
A 0.30% CuEQ cut-off is considered to be comparable to that used for open pit mining operations of copper porphyry deposits located in the Americas. All mineral resource estimates and cut-offs are subject to a feasibility study.

ConclusionsInvestment Highlights – A World-Class Investment Opportunity
State land, designated for mineral exploration and development Politically stable, established mining jurisdiction Rigorous laws and regulations, including NEPA. We believe the rule-of-law will prevail 1000 ft above sea level; gentle rolling terrain; no permafrost Very manageable water supplies
74
World-Class Resource
Most important, new greenfield copper-gold-molybdenum resource in the world. Well understood Current total resource includes a Measured and Indicated Resource of 5.9 billion tonnes containing 55 billion lbs copper,
66.9 million oz of gold and 3.2 billion lbs molybdenum, and Inferred Mineral Resources of 4.8 billion tonnes containing 25.6 billion lbs copper, 40.4 million oz gold and 2.3 billion lbs molybdenum (see Appendices)
Development could bring low cost power for Alaska and Southwest Alaska in particular-Stakeholder benefits Close proximity to tidewater and Asian markets Access to existing infrastructure The kind of long-life, potentially low cost asset that major mining companies covet Strong local management in Pebble Limited Partnership (PLP)
On an EV/Resource basis Northern Dynasty offers compelling value to investors and strategic buyers
US$10 million cash, no debt US$730 M+ invested to date in the Project Funding flexibility by a metal streaming, royalties, off-take agreements etc.
