Supporters of Minnesota copper mining often cite the Flambeau Mine near Ladysmith in north-central Wisconsin as an example of a mine that can run well, be played out and ultimately be “reclaimed” while not causing significant environmental problems.
While environmental groups cite ongoing issues with runoff at the Flambeau site, including high levels of copper in a small stream in excess of water quality standards, an August U.S. Court of Appeals decision ruled the company is not in violation of its permit. That decision is being interpreted by mining supporters in Minnesota as an example of a copper mine operating and closing without environmental doom predicted by critics.
The small Wisconsin deposit, discovered in 1969, was mined along the Flambeau River between 1993 and 1997, producing 181,000 tons of copper, 334,000 ounces of gold and 3.3 million ounces of silver.
“Yes, copper, nickel and other much needed metal production can and has been done safely and successfully, without polluting local waters,” the industry group Mining Minnesota notes in a recent publication. The Flambeau mine is “a great example of this success … and has since been closed and reclaimed in full compliance with Wisconsin laws.”
