10:12 AM EDT, 07/18/2025 (MT Newswires) -- (Updates with stock price movement in the headline and the first paragraph.)

Northern Dynasty Minerals ( NAK ) shares were down past 47% in recent Friday trading, a day after the company and its US-based subsidiary Pebble filed a motion in Federal District Court in Alaska.

The motion is seeking a summary judgment briefing schedule in the company's pending litigation regarding the lawfulness of a veto of a copper mining project by the administration of former US President Joe Biden.

Chief Executive Ron Thiessen said the company has not been able to reach a settlement with the US Environmental Protection Agency regarding the project.

"We asked the court to set a briefing schedule for summary judgment motions, as we now believe that will be the quickest, most direct avenue to get the veto removed," he said.
