The developers of a proposed copper-nickel mine upstream from the Boundary Waters Canoe Area Wilderness in northeastern Minnesota sued the Biden administration Monday to seek the reinstatement of federal mineral rights leases that are crucial to the $1.7 billion project.
Twin Metals Minnesota alleged in its lawsuit, filed in federal court in Washington, that the Department of the Interior acted illegally earlier this year when it canceled the leases. The company asked the court to declare that those leases remain valid and in force, so that it can proceed with the environmental review and permitting process.
