Federal judge deals another serious blow to proposed copper-nickel mine

MINNEAPOLIS -- A federal judge has dealt another serious setback to the proposed Twin Metals copper-nickel mine near the Boundary Waters Canoe Area Wilderness in northeastern Minnesota, dismissing the company's lawsuit that sought to regain the critical mineral rights leases that the Biden administration canceled.

The ruling Wednesday was the latest blow to the stalled $1.7 billion project, which has faced stiff opposition from environmental and tourism groups that say it would pose an unacceptable threat to the pristine wilderness along the U.S-Canadian border.

U.S. District Judge Christopher Cooper in Washington, D.C, ruled that the lawsuit failed to meet the legal requirements to proceed, essentially saying the court didn't have jurisdiction to overrule a series of federal agency decisions against the company.

Twin Metals, a subsidiary of the Chilean mining company Antofagasta, said in a statement that it was "disappointed" by the decision and was "working to determine next steps." Company spokeswoman Kathy Graul said in an email Thursday that she was not able to say what those next steps might be or whether they would include appeals to higher courts.

Groups that have been fighting the project for years hailed the ruling as a huge victory.

"Twin Metals was making a Hail Mary pass in its hope to get around the law and facts. The court saw through this and in its decision to toss out the case, affirmed science, affirmed the law, and protected some of the cleanest water in the country," Chris Knopf, executive director of Friends of the Boundary Waters Wilderness, said in a statement.

The Obama administration declined to renew Twin Metals' mineral rights leases in its final weeks in office in 2016, citing the threat of acid mine drainage to the Boundary Waters, the country's most-visited federally designated wilderness area. The Trump administration reinstated those leases in 2019 as part of its push to lessen U.S. dependence on imported metals.

But the Biden administration took up where the Obama administration left off, canceling the leases last year and and imposing a 20-year moratorium on mining in an area of the Superior National Forest upstream from the wilderness that includes the Twin Metals underground mine site near Ely, a community of about 3,000 people. The state of Minnesota then ended its environmental review of the project. Twin Metals sued the federal government last summer to try to undo its decisions.
