Courts dealt a major victory to environmentalists in the years-long battle over mining near Lake Superior.
The Minnesota Court of Appeals today rejected two copper-nickel mining permits for PolyMet Mining Corporation, adding another chapter in the fight over the fate over northern Minnesota’s watersheds.
A three-judge panel ruled that the state Department of Natural Resources needs to gather more information on the potential environmental impacts of the proposed mine and failed to impose a term limit on the mine when it issued permits in 2018.
The ruling does impact mining prospects near the 1-million-acre Boundary Waters Canoe Area Wilderness, an area at the heart of another hotly contested mining project by Twin Metals. But, according to the Star Tribune, it will likely result in major delays and financing hurdles for the PolyMet mine near Lake Superior.

Both mines have been stalled and restarted in the transition between the Obama and Trump administrations. And both cut to the heart of controversies involving job creation and environmental concerns near pristine, sparsely populated areas in northern Minnesota .
In 2018, the Trump administration canceled a moratorium on mining in the BWCAW, originally imposed by the Obama administration to conduct a thorough environmental impact assessment. The recent ruling does not address Twin Metals permits.
As a result of the ruling, the DNR will have to conduct a “contested case hearing,” which the agency previously declined to do. That hearing will involve expert testimony, cross-examination, and a recommendation by a judge to the DNR on whether to issue the permits.
