Twin Metals Copper-Nickel Mining Project

planned

The U.S. Congress has passed a measure to allow copper-nickel mining in northeastern Minnesota on federal lands adjacent to the Boundary Waters Canoe Area Wilderness. The project involves mining copper, nickel, cobalt, platinum, and palladium in the Duluth complex, the largest undeveloped mineral deposit of its kind in the U.S. The mining is proposed by Twin Metals Minnesota, a Chilean-owned company, with plans to use underground operations and dried tailings to minimize environmental impact.
