The US Bureau of Land Management (BLM) has agreed to reconsider its decision to renew 13 prospecting permits in Minnesota, which could have allowed Antofagasta’s Twin Metals to expand its proposed copper-nickel mine at the edge of the Boundary Waters Canoe Area Wilderness.
The move by the federal agency, part of the US Department of the Interior, comes in response to a lawsuit filed last year by conservation groups. They challenged a four-year extension of the permits, granted by former President Donald Trump.
“After the horrendous years of the Trump administration, federal officials now appear focused on rational, science-based decision making,” Marc Fink, a senior attorney at the Center for Biological Diversity, said in a statement.
“A thorough scientific analysis of these permits and Twin Metals’ related proposals will show that a massive copper-sulfide mine just upstream from the spectacular Boundary Waters Wilderness is simply too great a risk.”
Twin Metals holds a number of federal, state, and private mineral leases, as well as a number of prospecting permits on federal land in northeastern Minnesota.
