Mining Leases Canceled Near the Boundary Waters

By Hiroko Tabuchi for the New York Times

The Biden administration said Wednesday that it had canceled two mining leases that would have allowed a copper mine to be built near an area of pristine wilderness in Minnesota.

The Interior Department said it had determined that the leases, held by Twin Metals Minnesota, a subsidiary of the Chilean mining conglomerate Antofagasta, were improperly reinstated by the Trump administration in 2019.
