 This meant the tribes could set their own, potentially far more restrictive limits than those of the state Department of Natural Resources, essentially meaning a potential Crandon mine would have to be completely free of pollution.This was the end of the economic viability of the project, and on October 28, 2003, the Mole Lake Ojibwe and Forest County Potawatomi used $16.5 million worth of casino revenue to purchase the mine site and Nicolet Minerals Inc., its latest owner.Neither tribe has plans to develop the site in the foreseeable future.
