New Report Reveals Inadequate Monitoring and Mitigation Practices at Flambeau Mine

A new report reviewing mining industry practices at the now-closed Flambeau Mine1 near Ladysmith, Wisconsin exposes how crucial environmental monitoring data have been withheld from the public. The Flambeau Mine, considered state of the art by today’s standards, has been promoted by supporters of the PolyMet and Twin Metals projects in Minnesota as an example of a copper mine that operated “without polluting local waters.” Similar claims have been made by proponents of the Back Forty project on the Michigan/ Wisconsin border, the Eagle and Copperwood projects in Michigan, the GTac, Bend and Reef projects in Wisconsin, and the Pebble project in Alaska. It’s as if the Flambeau Mine has become the industry’s calling card.
