The Menominee Indian Tribe of Wisconsin is appealing U.S. District Judge William Griesbach's rejection of the tribe's challenge to a state permit for Aquila Resources Inc.'s Back Forty zinc-gold project, The Associated Press reported Jan. 17.
Aquila received its wetlands, lakes and streams permit from the Michigan Department of Environmental Quality for Back Forty in June 2018.
The tribe argues that the U.S. Environmental Protection Agency wrongly allowed Michigan to handle permitting for the project and applied to the Seventh U.S. Circuit Court of Appeals looking to overturn the rejection of its lawsuit.
A feasibility study on the project in 2018 outlined a net present value, discounted at 6%, of US$208 million for a mine with a seven-year life.
