The Twin Metals mine is a potential copper sulfide mine near Ely, Minnesota, on Superior National Forest land. There has been significant opposition to the proposed mine, most notably because of its proximity to the Boundary Waters Canoe Area Wilderness, location within a watershed that drains into the BWCA, and the air, water, light and noise pollution and traffic effects of converting a forested area bordering the BWCA into a substantial industrial mining facility.
