Northern Dynasty: Update of Timelines for Summary Judgement Case

VANCOUVER, BC / ACCESS Newswire / February 16, 2026 / Northern Dynasty Minerals Ltd. (TSX:NDM)(NYSE American:NAK) ("Northern Dynasty" or the "Company") and its 100%-owned, U.S.-based subsidiary Pebble Limited Partnership ("Pebble Partnership") provide an update of court mandated timelines for litigation pending in the Federal District Court in Alaska.

The plaintiffs (the State of Alaska, Pebble Partnership and Iliamna Natives Ltd. and Alaska Peninsula Corp.) filed their summary judgement briefs on October 3, 2025. The Department of Justice ("DOJ") must file its brief on or before February 17, 2026. The plaintiffs, including the Pebble Partnership, must file final briefs by April 15, 2026.

"This administration has repeatedly stated its commitment to removing permitting barriers for oil and gas, pipeline and mining in America. We view the Obama-Biden era veto on mining activity at one of the world's largest undeveloped deposits of copper, gold, molybdenum, silver, and rhenium in Alaska as the most consequential and far-reaching permitting obstruction of its kind," Ron Thiessen, Northern Dynasty President and CEO stated. "In addition, if allowed to stand, this unlawful veto can serve as a "kill switch", establishing precedent that future administrations could invoke to halt or reverse progress made in advancing responsible natural resource permitting."

"Our preferred outcome is to reach a settlement of this litigation that withdraws the veto and dismisses the case. Until we can reach that result, however, we continue to aggressively pursue litigation with confidence that we will prevail. We will promptly review EPA's February 17 filing and respond accordingly in a few days," Mr. Thiessen continued.
