F-10/A: Northern Dynasty Minerals Files US$75 Million Shelf Prospectus Amidst Ongoing Pebble Project Legal Battles

Northern Dynasty Minerals Ltd. has filed an amended shelf prospectus to offer up to US$75 million in various securities, primarily to fund ongoing legal challenges against federal permit denials for its Pebble Project and maintain operations.

Summary

• Northern Dynasty Minerals Ltd. (NDM on TSX, NAK on NYSE American) has filed an F-10/A amendment for a base shelf prospectus, allowing it to offer up to US$75,000,000 in common shares, warrants, subscription receipts, debt securities, or units over a 25-month period.
• The Company's primary business objective is the exploration and advancement of the Pebble Project, a copper-gold-molybdenum-silver-rhenium mineral deposit located in southwest Alaska.
• The Pebble Project faces significant permitting challenges, with the U.S. Army Corps of Engineers (USACE) denying its permit application in November 2020 (2020 ROD) and again in April 2024 (2024 ROD), based on the U.S. Environmental Protection Agency's (EPA) Final Determination issued in January 2023.
• The EPA's Final Determination imposes limitations, including a 'Defined Area for Prohibition' (24.7 square miles) and a 'Defined Area for Restriction' (309 square miles), on the use of certain waters in the Bristol Bay watershed for discharges associated with the Pebble Project.
• Northern Dynasty and its subsidiary, the Pebble Partnership, are actively challenging the EPA's Final Determination and the USACE's RODs in U.S. federal court, including a claim that the Final Determination constitutes an unconstitutional 'taking' of property.
• An independent Preliminary Economic Assessment (2023 PEA) for a proposed 20-year, 180,000 tons per day open pit operation at Pebble projects positive financial results, but is preliminary and includes inferred mineral resources, which are geologically speculative.
• The Company has secured US$36 million from a Royalty Agreement (US$12 million initial in July 2022, US$2 million in November 2023, US$10 million in July 2024, and US$12 million in June 2025), with the potential for an additional US$24 million from the Royalty Holder.
• Other recent financings include a $3.4 million non-brokered private placement in December 2023 and the issuance of US$15 million in 10-year convertible notes in December 2023, which carry a 150% redemption premium if the Company undertakes a future equity financing.
• As of the prospectus date (July 2, 2025), the Company had approximately $25.4 million in cash resources, which is deemed sufficient to fund its estimated $18.0 million (US$13 million) in expenditures for the next twelve months, primarily for legal challenges and corporate expenses.
• The Company anticipates continued negative operating cash flow and will require substantial additional financing beyond the next twelve months, with no assured arrangements in place other than the Royalty Agreement.

Sentiment

Score: 3

Explanation: The company faces severe regulatory and legal headwinds for its sole project, leading to significant uncertainty regarding its future development and profitability. While it has secured some financing and has a plan for the next 12 months, the long-term financial viability is highly dependent on overcoming these substantial challenges, which are explicitly stated as having no assurance of success.

Positives

• Secured US$36 million in royalty payments from the Royalty Agreement, with an option for the Royalty Holder to provide an additional US$24 million.
• The 2023 Preliminary Economic Assessment (PEA) for the Pebble Project indicates positive projected financial results and demonstrates optionality for future mine development.
• The Company has sufficient cash resources, approximately $25.4 million, to fund its estimated $18.0 million (US$13 million) in expenditures for the next twelve months without immediate additional financing.
• Successfully settled class action lawsuits in both the U.S. and Canada, resolving significant legal liabilities.
• The U.S. Federal District Court in Alaska granted the Company's motion to add the USACE as a defendant in its ongoing lawsuit against the EPA, consolidating legal challenges.

Negatives

• The Pebble Project's permit application was denied by the USACE in 2020 and again in 2024, based on the EPA's Final Determination, which imposes significant restrictions and prohibitions on mining activities.
• Ongoing legal challenges against the EPA's Final Determination and the USACE's permit denials are costly, protracted, and have no assurance of success.
• The Company's 'takings' action against the U.S. government, seeking compensation for the effective loss of property rights, is currently stayed pending the outcome of other litigation.
• The Company has a history of financial losses and anticipates continued negative operating cash flow for the foreseeable future, as it currently generates no revenues.
• Substantial additional capital will be required beyond the next twelve months, and there are no assured financing arrangements in place for this future funding.
• The terms of the US$15 million Convertible Notes include a 150% redemption premium if the Company completes a future equity financing, which could impair its ability to secure such financing.
• The Pebble Project is the Company's only mineral property interest, making its future highly dependent on overcoming the significant regulatory and legal hurdles.
• The 2023 PEA is preliminary and includes inferred mineral resources, which are considered too speculative geologically to be categorized as mineral reserves, indicating a high level of project uncertainty.
• The project faces concerted political and environmental opposition, which could further delay or increase the cost of development.
• Uncertainty regarding the long-term availability and cost of natural gas in Southcentral Alaska could impact project design and operating costs.
• The Company is cooperating with an ongoing grand jury investigation, the outcome of which is uncertain and could result in charges or further inquiries.
• Despite class action settlements, individual 'opt-out' shareholders retain the ability to bring their own lawsuits, potentially leading to further litigation expenses and damages.
• The Company's likely status as a 'passive foreign investment company' (PFIC) has possible adverse U.S. federal income tax consequences for U.S. investors.
• The Company is a Canadian foreign private issuer, meaning U.S. investors receive less extensive and timely information compared to U.S. domestic issuers.

Risks

• Unsuccessful appeal of the Record of Decision and challenge to any Final Determination issued by the EPA, potentially preventing the Company from obtaining required environmental permits for the Pebble Project.
• Inability to ultimately achieve mine permitting and build a mine at the Pebble Project due to regulatory actions, political opposition, or other factors.
• The current project plan for the Pebble Project in the 2023 PEA is not supported by any pre-feasibility or feasibility study, carrying a substantial risk that the project will not be economically viable or proceed as envisioned.
• Uncertainty regarding the long-term availability of natural gas in Southcentral Alaska, which could lead to changes in project design or significant cost increases.
• Risk of incurring further litigation expenses or being subject to new lawsuits, including from 'opt-out' plaintiffs from previous class action settlements, and potential judgments for damages.
• Uncertain outcome of current or future government investigations and inquiries, including a federal grand jury investigation in Alaska, which could have a material adverse impact on the Company's prospects.
• The 2020 and 2024 RODs and the EPA's Final Determination have had an ongoing adverse impact on Northern Dynasty's ability to finance the Pebble Project, and this may continue.
• Limited capital resources, negative operating cash flow, and significant future financing requirements, with no assurance that such funding will be achieved when required.
• Uncertainty regarding secure title or property interest for the Company's mineral claims.
• The Pebble Project is subject to concerted political and environmental non-governmental opposition, which may delay or halt development and increase costs.
• The Pebble Partnership's mineral property interests do not contain any mineral reserves or known body of economic mineralization, meaning the project is currently an exploration prospect only.
• Mineral resources disclosed are estimates only, and there is no assurance that any mineral resources will ever be upgraded to mineral reserves or be commercially viable.
• No assurance that Northern Dynasty will be able to enter into an arrangement with a partner for the development of the Pebble Project.
• Northern Dynasty has no history of earnings and no foreseeable earnings, and may never achieve profitability or pay dividends.
• The Company's financial statements are prepared assuming it will continue as a going concern, but this is dependent on economically recoverable mineral reserves, financing, and permits.
• Failure to establish that the Pebble Project possesses commercially viable and legally mineable deposits of ore may cause a significant decline in share price and impair financing ability.
• If prices for copper, gold, molybdenum, silver, and rhenium decline, Northern Dynasty may not be able to raise the additional financing required.
• Recent changes to U.S. trade policies and tariff risks may adversely impact commodity markets, supply chains, and the development of the Pebble Project.
• Volatility of commodity prices, which are affected by numerous factors beyond the Company's control, impacts profitability and financial condition.
• Information systems and cyber security risks, including network disruptions, security breaches, and cyber-attacks, could result in material loss or damage to reputation.
• The Russian-Ukrainian and Israel-Hamas conflicts could detrimentally affect the global economy and the Company's business and share price.
• Mining is inherently dangerous and subject to conditions or events beyond the Company's control, which could cause injuries, property damage, or environmental contamination.
• Northern Dynasty competes with larger, better capitalized competitors in the mining industry, potentially limiting its ability to acquire financing, personnel, or properties.
• Compliance with environmental requirements will take considerable resources, and changes to these requirements could significantly increase costs or delay activities.
• The Company is subject to many risks that are not insurable, meaning it may not be able to recover losses through insurance should certain events occur.
• Loss of key personnel could delay or increase the cost of operations.
• The volatility of Northern Dynasty's common shares can expose the Company to the risk of litigation.
• Likely PFIC status has possible adverse U.S. federal income tax consequences for U.S. investors.
• As a Canadian company, shareholder protections differ from those in the United States and elsewhere.
• As a foreign private issuer, the Company is exempt from certain U.S. securities rules, providing less extensive and timely information to U.S. investors.
• An investment in the Company's securities is speculative and may result in the loss of the entire investment.

Future Outlook

The Company's future outlook is primarily focused on challenging the EPA's Final Determination and the USACE's permit denials for the Pebble Project through ongoing legal actions. It aims to maintain its corporate presence in Alaska and Washington D.C., keep the Pebble Project claims in good standing, and actively seek a strategic partner with greater financial resources to advance the project. The Company anticipates continued negative operating cash flow for the foreseeable future, as it currently generates no revenues, and will require substantial additional financing beyond the next twelve months to fund future exploration and development activities. The ability to secure this financing is expected to be negatively impacted by the ongoing regulatory and legal challenges.

Management Comments

• The Company believes the results of the EIS support the 2019 withdrawal of the Original Proposed Determination.
• The Company and the Pebble Partnership claim that the USACE's refusal to proceed with the Remand Process is contradictory and prejudicial to the Company and the Pebble Partnership as the EPA's Final Determination is based on the USACE's conclusions which are, in part, required to be reviewed under the Remand Process.
• The Company consented to a motion from the EPA and USACE to hold the litigation in abeyance for 90 days to allow for leadership of the two agencies under the new U.S. administration to decide how to proceed, with subsequent extensions.
• It remains the Company's position that the withdrawal of the preemptive veto by the EPA was sound and appropriate.
• The Company has sufficient cash resources to fund its plan of operations over the next twelve months without additional financing.
• The Company believes that its ability to obtain additional financing has been and will continue to be negatively impacted by the 2020 ROD, the 2024 ROD, the Final Determination, and the USACE's determination not to proceed with the Remand Process.
• The Company expects that an unsuccessful challenge to the Final Determination will negatively impact its ability to secure additional financing, likely limiting options to further equity issuances.

Industry Context

This filing highlights the significant regulatory and environmental challenges faced by large-scale mining projects, particularly those in ecologically sensitive regions like Alaska's Bristol Bay. The ongoing legal battles with the EPA and USACE underscore the increasing scrutiny and opposition that resource development projects can encounter, often leading to prolonged permitting processes and substantial legal costs. The Company's reliance on a single major project (Pebble) also illustrates the high-risk, high-reward nature of mineral exploration, where success is heavily contingent on overcoming external regulatory and political hurdles, in addition to geological and economic factors. The mention of IFRS accounting standards and the Multijurisdictional Disclosure System (MJDS) also reflects the complexities of operating and reporting for a Canadian issuer with U.S. listings.

Comparison to Industry Standards

• The Company's financial statements are prepared in accordance with IFRS Accounting Standards, as issued by the IASB, which may not be comparable to financial statements of United States companies prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP).
• The Company, as a Canadian issuer, complies with Canadian National Instrument 43-101 (NI 43-101) for mineral property disclosure, which differs from the SEC Modernization Rules for U.S. domestic issuers, potentially leading to different reporting of mineral resources.
• The 2023 PEA is preliminary in nature and includes inferred mineral resources, which are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves, a common characteristic of early-stage projects but also a significant risk factor compared to projects with established reserves.

Corporate Governance

Legal Proceedings

• The Company and Pebble Partnership have commenced an action in U.S. federal court in Alaska challenging the EPA's Final Determination to veto development at Pebble and seeking to vacate it.
• The Company and Pebble Partnership filed an action in the United States Court of Federal Claims in Washington, DC, claiming that the EPA's actions constitute an unconstitutional 'taking' of their property, which is currently stayed.
• The State of Alaska filed a Motion for Leave to File a Bill of Complaint with the United States Supreme Court challenging the Final Determination, but the Supreme Court declined to hear the case directly.
• The State of Alaska filed its own 'takings' action in the United States Court of Federal Claims in Washington, DC, which has also been stayed.
• The State of Alaska filed an action in Federal District Court in Alaska seeking to vacate the EPA veto, which has been consolidated with the Company's action.
• Iliamna Natives Limited ('INL') and Alaska Peninsula Corporation ('APC') filed suit against the EPA for exceeding its authority with the veto action against Pebble, and this action has been consolidated with the Company's action.
• The Company is cooperating with a grand jury investigation involving the United States Attorney's Office for the District of Alaska, with an uncertain outcome.
• The Company has settled proposed class action lawsuits in the U.S. and Canada, but individual shareholders who 'opted-out' of the U.S. settlement retain the ability to bring their own lawsuits, potentially leading to further litigation expenses and damages.

Stakeholder Impact

• Shareholders face significant risk of dilution from potential future equity financings and the possibility of losing their entire investment due to the high-risk nature of the business and the severe challenges facing the Pebble Project.
• U.S. shareholders may face adverse U.S. federal income tax consequences due to the Company's likely status as a 'passive foreign investment company' (PFIC).
• Shareholder protections differ under Canadian law compared to U.S. law, and as a foreign private issuer, the Company provides less extensive and timely information to U.S. investors.
• Local communities in Bristol Bay, particularly Alaska Native village corporations like Iliamna Natives Limited and Alaska Peninsula Corporation, are directly impacted by the project's development status and the EPA's veto, with some supporting the project for potential economic benefits and others opposing it for environmental reasons.
• Creditors, particularly holders of the Convertible Notes, have specific terms that could impact future financing, such as a 150% redemption premium if the Company undertakes an equity financing.

Next Steps

• Continue with primary corporate objectives of challenging the EPA's Final Determination and the USACE's 2020 and 2024 RODs, including the USACE's denial of the permit.
• Maintain an active corporate presence in Alaska to advance relationships with political and regulatory offices of government (both in Alaska and Washington, D.C.), Alaska Native partners, and broader stakeholder relationships.
• Maintain the Pebble Project and Pebble claims in good standing.
• Continue to seek potential partner(s) with greater financial resources to further advance the Pebble Project.
• Continue general and administrative activities in connection with the advancement of the Pebble Project.
• If successful in legal challenges, secure the full range of permits and authorizations from multiple federal and state regulatory agencies, which is expected to take several years.
• Finalize the project plan for the Pebble Project, including the financial results of the 2023 PEA.
• Complete feasibility studies demonstrating that any Pebble Project mineral resources can be economically mined.
• Complete all necessary engineering for mining, processing, and infrastructure facilities.
• Secure significant additional financing, including that associated with the full Royalty Agreement, to fund these objectives as well as funding mine construction.
• Re-assess options for advancing the development of the Pebble Project if unsuccessful in challenging the Final Determination.
• Continue to evaluate the availability of long-term project financing options among mining companies, private equity firms, and others, utilizing conventional asset level financing, debt, royalty, and alternative financing options.
