Northern Dynasty Shares Plunge After DOJ Backs EPA’s Pebble Mine Veto in Alaska Court Fight
Shares of Northern Dynasty Minerals Ltd. tumbled sharply Wednesday after the U.S. Department of Justice (DOJ) filed a court brief supporting the U.S. Environmental Protection Agency’s (EPA) veto of the controversial Pebble mineral project in southwest Alaska. The filing marked a key procedural development in the ongoing legal challenge over the permit-blocking decision and sent Northern Dynasty’s stock to multi-month lows on heavy trading.
The DOJ brief, submitted in U.S. District Court in Alaska, aligns federal legal support behind the EPA’s 2023 veto under Section 404(c) of the Clean Water Act, which aimed to restrict mining discharge into the Bristol Bay watershed near one of the world’s richest salmon ecosystems. Northern Dynasty and allied plaintiffs — including the State of Alaska and local corporations — are pursuing summary judgment, asking the court to overturn the veto without a full trial.
Investors reacted sharply to the development, with Northern Dynasty’s stock sliding as much as 45% from recent levels before midday trading, reflecting deep concerns over the project’s future and the implications of federal agencies defending the veto in court.
Management at Northern Dynasty criticized the DOJ’s position, saying that defending the veto sets a precedent that could deter future resource permitting and undercut broader pro-mining policy goals promoted by some federal officials. Company leadership has said it will thoroughly review the filing with its legal team before issuing detailed comments.
The Pebble project — which contains large undeveloped deposits of copper, gold, molybdenum and other minerals — has been at the center of a heated regulatory and political dispute for years, balancing economic development interests against environmental and Indigenous community concerns. The current legal phase, focused on procedural briefing deadlines, is expected to conclude with final plaintiff briefs in April, potentially setting the stage for judicial rulings later this year.
