Copper Mining

Minnesota lawmakers are ramping up efforts to prevent mining companies from gaining a foothold in Minnesota with legislation that aims to slow or ban copper-nickel mining in the state's northeastern Iron Range.

U.S. Rep. Betty McCollum says she has won assurances from the Trump administration that it will proceed with a two-year study on whether copper-nickel mining should be permitted on federal lands in the watershed that flows into the Boundary Waters Canoe Area.
