From the 1980s to 2003, Crandon was the center of an environmental debate to construct a mining operation at the proposed Crandon mine, a rich copper deposit discovered by the Exxon Coal and Minerals Company. The heated discussion led to a Wisconsin Legislature mining moratorium act in 1998. Eventually, the proposed company and mine site lands were purchased by the opposed Mole Lake Sakaogon Chippewa and Forest County Potawatomi tribes, whose reservations sat near the site. The project was withdrawn in October 2003.
