The Minnesota Court of Appeals on Monday reversed two mining permits issued for PolyMet Mining Corporation, hindering the mining companies plan to construct a copper-nickel mine in the northeastern part of the state.
The permits were issued by the Minnesota Department of Natural Resources (DNR), but Chief Judge Edward Cleary said that the DNR erred in not holding a contested case hearing on the permits to fully vet objections by environmental groups and the Fond du Lac Band of Lake Superior Chippewa.
