Kopernik Global Investors, LLC Files Early Warning Report in Respect of Northern Dynasty Minerals Ltd.
Kopernik raises its Northern Dynasty stake to 14.69%, leaving its position 53% underwater on the new purchases.

Northern Dynasty Minerals Ltd. (NDM) filed a shareholder early warning report on November 12, 2026, disclosing a significant increase in its stake by Kopernik Global Investors, LLC. The Tampa-based firm raised its position from 38,410,280 shares plus US$12,864,000 in convertible notes, representing approximately 12.68% on a partially diluted basis, to 49,370,155 shares plus the same notes. This new holding equates to 14.69% on a partially diluted basis, marking an accumulation period of roughly twelve months since the prior early warning report was filed on November 13, 2025.
Kopernik acquired 10,959,875 shares on the NYSE American at an average price of US$1.269 (C$1.8147), totaling US$13,908,081 (C$19,888,885). An additional 2,244,703 shares were received via client transfers, meaning approximately 11.0 million of the 13.2 million share increase resulted from open-market buying. The firm’s convertible note position remains at US$12,864,000 in principal, which is convertible into 36,165,308 shares. This implies a conversion price of approximately US$0.356 per share. Against the current share price of approximately US$0.60 (C$0.86 at a C$1.43/US$ exchange rate), the conversion is deep in the money.
On a basic outstanding share count of 562,191,662 as of November 12, 2026, Kopernik holds 8.78%. The headline figure of 14.69% includes the 36,165,308 shares underlying the notes, bringing the partially diluted total to 598,356,970 shares. Kopernik stated it may engage in discussions regarding board composition and governance, reserving the right to solicit shareholders or third parties on potential business combinations or dispositions, recommend changes to capitalization or ownership structure, and buy, sell, short sell, or hedge its position, including through swaps and derivatives. Ms. Isabel Satra, a Kopernik principal and CFO, has served on the NDM board since March 24, 2023. David B. Iben, Co-CIO and controlling member of Kopernik, is listed as a joint actor. The report indicated no present plan or proposal under Item 5(a)-(k) beyond the acquisitions themselves.
At the current price of C$0.86, the 10.96 million new shares purchased at an average of US$1.269 are worth approximately US$0.60 each, resulting in an unrealized loss of approximately US$7.3 million, or 53%, on those specific purchases. The stock closed at C$0.86 on November 12, within 5% of its 52-week low of C$0.82 set one week earlier. This price action follows a period of significant volatility and regulatory delay. The stock was trading at C$2.43 when the prior early warning report was filed in November 2025. Following a 43-day federal court shutdown that began on November 19, 2025, industry amicus briefs were filed in support on December 1, 2025. The DOJ filed a brief defending the EPA veto on February 17, 2026, causing the stock to gap from C$2.76 to C$1.71, a decline of 38%, on February 18, 2026.
The company filed its reply on April 14, 2026, and all briefs were closed by April 23, 2026. Oral argument was held on schedule on June 25, 2026, and the matter was declared "ripe for decision" on June 26, 2026. No ruling has been issued in the approximately 4.5 months since, during which time shares have fallen from C$2.67 to C$0.86, a decline of 68%.
Northern Dynasty Minerals Ltd. (NDM) filed a legally mandated disclosure confirming that an existing institutional holder has crossed a reporting threshold. This filing follows a pattern previously disclosed on November 13, 2025, and was executed through open-market accumulation and client transfers. The filing does not alter the company’s position regarding Pebble, the EPA Section 404(c) veto litigation, the permitting path, the balance sheet, or the capital structure.
The institutional investor committed approximately US$13.9 million in open-market purchases at an average price roughly double the stock’s current quote. This activity marks a one-year continuation of the shareholder’s known stance. The stock closed near a 52-week low on the day of the filing.
The shareholder accumulated its position during a 75% drawdown and is now materially underwater on those purchases. The investor holds board seats and has disclosed mechanisms including business combinations or dispositions, short selling, and hedging. The filing explicitly reserves the right to short sell or hedge.
Regarding dilution, US$12.864 million of convertible notes convert into 36.2 million shares, representing approximately 6.0% of the partially diluted count. This conversion occurs at an implied price of approximately US$0.36. The company receives no new cash from this conversion, and existing holders absorb the 36 million shares at a price 40% below the current market. Management’s reference to 14.69% dilution depends on this conversion occurring.
The financial figures referenced are from the prior period, which ended June 30, 2026, and are not disclosed in today’s release.
Northern Dynasty Minerals Ltd. (NDM) is a pre-revenue, single-asset development company holding a 100% position in the Pebble deposit. The interest consists of 1,840 contiguous mineral claims in southwest Alaska, located approximately 200 miles from Anchorage and 125 miles from Bristol Bay. The claims are held through the wholly owned Pebble Limited Partnership. The company currently has no revenue, no defined reserves, no operating mine, and no permits.
According to the 2023 Preliminary Economic Assessment (PEA) using a 0.3% CuEq cutoff, the deposit contains Measured and Indicated resources of 6,456 Mt at 0.76% CuEq, comprising 0.40% Cu, 1.7 g/t Ag, and 240 ppm Mo. This category contains approximately 53.0 billion pounds of recoverable copper and 53.8 million ounces of recoverable gold. Inferred resources total 4,454 Mt at 0.55% CuEq, representing approximately 33% of the total resource. No mineral reserves have been defined.
The proposed base case operation envisions a 20-year mine life with 180,000 tonnes per day of conventional flotation processing, milling 1.3 billion tonnes at a 0.12:1 strip ratio. Annual output is projected at approximately 320 million pounds of copper, 368,000 ounces of gold, 15 million pounds of molybdenum, and 1.8 million ounces of silver.
Economic metrics for the base case include a post-tax net present value (NPV) of US$2,233 million at a 7% discount rate, an internal rate of return (IRR) of 16.2%, and a payback period of 4.6 years. These figures are based on US$6.77 billion in total initial capital, consisting of a US$3.116 billion net cash outlay plus US$2.64 billion in third-party infrastructure, against a US$1.2 billion anticipated streaming contribution. Life-of-mine taxes and government royalties are estimated at US$1,487 million.
The project includes expansion optionality, such as a year-5 expansion to 270,000 tonnes per day, which yields an NPV of US$8,570 million and an IRR of 22.0% on an 8.6 billion tonne resource base. Additional conceptual expansion scenarios include a year-10 NPV of US$7,520 million and a year-21 NPV of US$5,500 million. These expansion scenarios are conceptual and unpermitted.
The Final Environmental Impact Statement (EIS) was released in July 2020. The U.S. Army Corps of Engineers issued a negative Record of Decision on November 25, 2020. An EPA Section 404(c) veto remains in place. The company is pursuing a dual-track strategy involving litigation in Alaska Federal District Court and the Court of Federal Claims, alongside administrative and legislative negotiations. The State of Alaska, Iliamna Natives Ltd., and Alaska Peninsula Corp. are co-plaintiffs in the litigation, while six Native Village corporations have litigated against the veto.
The infrastructure concept includes a 72-mile access road with an ice-breaking ferry, a year-round Cook Inlet port, a 270 MW gas-fired plant, and a 168-mile gas pipeline. These facilities are intended for third-party build and ownership in exchange for tolls.
The design and environmental, social, and governance (ESG) framework features two lined tailings facilities with PAG backfill to the pit at closure, no permanent waste rock piles, and no cyanide use. The facility is designed for seismic activity up to 0.61g MCE. A "Pebble Performance Dividend" provides a 3% net profit royalty interest to full-time Bristol Bay residents, with a minimum of US$3 million per year from construction.
