Flambeau Mine
Rusk County, United States
The Flambeau Mine was an open pit mine of a copper-gold deposit near the Flambeau River, south of Ladysmith, Wisconsin, United States. It was mined by a subsidiary of Kennecott Minerals between 1993 and 1997, and returned to a fairly natural state after. As of 2022, it was "the only example of a metallic mine that was permitted, constructed, operated, and reclaimed under [Wisconsin's] existing regulatory framework."
