Wisconsin activists: Proposed Back Forty Mine in Michigan UP a risk to waters, Menominee sites

September 28, 2021

A coalition of Indigenous and non-Indigenous environmental activists are rallying against a proposed new project in Michigan’s Upper Peninsula they believe could lead to activities that could pollute Wisconsin waterways.

The Coalition to Save the Menominee River formed in April 2017 to oppose the Back Forty Mine project, which is a proposed open-pit sulfide mine that would operate on 83 acres and extract zinc, gold, copper, lead and silver.

Many are concerned that when sulfide ores are mined from the earth and exposed to air and water they undergo chemical reactions that create sulfuric acid that harms water quality and is toxic.
