The state Court of Appeals has extended a hold on three permits for PolyMet's proposed copper-nickel mine in northern Minnesota.
The court order released Thursday said the temporary stays will remain in effect until the court decides the merits of appeals filed by the Fond du Lac Band of Lake Superior Chippewa and several environmental groups. The court has 90 days to file its decision.
The order comes one day after the Court of Appeals heard oral arguments from the groups, who have asked the court to reverse the permits as well as a decision by the Minnesota Department of Natural Resources (DNR) not to allow a contested-case hearing on the matters.
"Based on the record and the arguments of the parties, we conclude that it is appropriate to continue the stay through this court's disposition of the appeals," Chief Judge Edward Cleary wrote.
The appeals are central to the groups' fierce opposition to PolyMet Mining's project, a proposed open-pit mine that would operate on the Iron Range near Babbitt and Hoyt Lakes. It would be the state's first major nonferrous mine.
Fond du Lac Band spokeswoman Rita Aspinwall said the tribe was "pleased" with the court's move.
So was WaterLegacy lawyer Paula Maccabee.
"What it means for Minnesota is that our wetlands, our waters and our habitats will be protected until the court has a chance to make a thoughtful decision on whether the permits should be reversed and whether a contested case should be heard," she said.
