The operators of the planned Twin Metals mine near Ely are suing the federal government, after the Biden administration cancelled the leases for the copper-nickel operation in January.
Filed Monday, the suit is the latest volley in a long tussle over whether the sprawling underground hard-rock mine should be able to operate within the watershed of the federally protected Boundary Waters Canoe Area Wilderness.
In a complaint filed Monday in U.S. District Court in Washington, D.C., a Twin Metals representative said the mine should be able to proceed through federal review.
"We are standing up for our right to a fair and consistent environmental review of our proposed mining project," wrote Dean DeBeltz, Twin Metals' director of operations, in a statement.
The suit names the Interior Department, the Bureau of Land Management and officials from those agencies, including Interior Secretary Debra Haaland. The plaintiffs are Twin Metals Minnesota — a subsidiary of Chilean mining giant Antofagasta — and Franconia Minerals, a subsidiary of Twin Metals.
Representatives of Interior and BLM declined to comment.
The lawsuit asks the court to set aside several federal decisions against the mine, declare that the leases are again valid and extend the time that Twin Metals has to secure permits and meet other milestones.
The leases for the mine were granted in 2019, under the administration of former President Donald Trump. But after Joe Biden took office in 2021, "the defendant officials within the Department of the Interior exacted a tightly coordinated set of unlawful actions targeting Twin Metals' rights and property interests," the lawsuit contends.
