In a victory for PolyMet Mining Corp., the state Court of Appeals said Tuesday that a plan to open Minnesota’s first copper-nickel mine can move forward without a new environmental review.
The ruling resolves the first of several lawsuits filed by environmental groups since the state Department of Natural Resources (DNR) issued PolyMet a set of permits last year to construct the $1 billion mine near Hoyt Lakes.
With federal and state permits in hand, those lawsuits are the last major legal hurdle PolyMet needs to clear before it can begin work on what it calls its NorthMet mine.
