polymet mine

Environmentalists have filed another lawsuit seeking to prevent the U.S. Forest Service from swapping land for the planned PolyMet copper-nickel mine in northeastern Minnesota.

Two environmental groups are suing to block a land exchange for the planned PolyMet copper-nickel mine in northeastern Minnesota, saying the project would destroy important habitat for the gray wolf and Canada lynx.

Gov. Mark Dayton says his administration's approval of the final environmental review for the proposed PolyMet copper-nickel mine isn't the final call on whether the project will move ahead.
