A copper and nickel mine in northeastern Minnesota that was halted by the Biden administration is now seeking a Clean Water Act permit and asking state regulators to advance the project.

Developers of the $1.5 billion NorthMet mine — which has GOP support but faced years of pushback from tribes and environmental groups — have submitted a new application to the U.S. Army Corps of Engineers for a Section 404 wetland permit.

NewRange Copper Nickel is also asking the Minnesota Department of Natural Resources to complete a supplemental environmental review and said in a release that it’s made “enhancements” to its proposal to include additional engineering, data and input. The company is a joint venture between Teck Resources and Glencore.

“NewRange is forging the next chapter of this historic northern Minnesota mining district,” Tannice McCoy, the company’s president and general manager, said in a statement.
