 The Sierra Club, the Wisconsin Resources Protection Council, a non-profit environmental group dedicated to providing information about large scale metallic sulfide mining, and the Mining Impact Coalition, a grassroots organization dedicated to protecting and preserving natural and cultural communities, were among the many groups in opposition to the mine.The proposed mine would be near the headwaters of the Wolf River and environmentalists claimed that there was a high potential for damage to the water quality, as well as the living things that reside in the river.In addition to the negative environmental effects on the Wolf River, the Sokaogon Chippewa, as well as the Menominee, who resided directly downstream from the proposed mine, were facing the potential for their food sources to be contaminated.
