The federal government gave Twin Metals Minnesota the green light to explore controversial mining opportunities near the Boundary Waters Canoe Area Wilderness, which have been the focus of heated debate for years.

After overturning an Obama-era ban on mining near the BWCAW last year, the Department of the Interior renewed Twin Metals’ mineral leases Wednesday, according to the Duluth News Tribune. The move raised fears that potentially harmful runoff from copper-nickel mining could impact two of America’s most pristine wilderness areas.
Both Twin Metals and Polymet Mining possess mineral leases to prospect mining projects near Superior National Forest that date back years – decades in Twin Metals’ case. The latter company currently has mining proposals under public comment. Both corporations saw those leases hit a wall near the end of the Obama administration in the wake of strong public opposition, including Amy and Dave Freeman’s yearlong Boundary Waters encampment.
