MINNEAPOLIS (AP) — A federal judge on Tuesday rejected a challenge by environmental groups against the proposed Twin Metals copper-nickel mine in northeastern Minnesota, saying the Interior Department had the authority to reverse itself and renew the project’s federal mineral rights leases.
The Obama administration tried to kill Twin Metals by rejecting the company’s application to renew its leases, citing the risk of acid mine drainage to the nearby Boundary Waters Canoe Area Wilderness.
