Aquila Resources, a Canadian exploration company that has never operated a mine before, has proposed an open pit metallic sulfide mine deeper than the height of Wisconsin’s tallest building, Milwaukee’s U.S. Bank tower. The Wisconsin and Michigan chapters of the Sierra Club and dozens of other groups oppose the Back Forty sulfide mine proposal for a number of reasons. The proposed 750-feet deep open pit mine alone would be located 50 yards from the Menominee River that serves as the Wisconsin-Michigan border. 70 million tons of acid-producing waste rock and milled tailings would be produced – far larger than the Crandon mine proposal defeated in 2003 after more than 30 years of opposition.
The mine pit would consume 84 acres of land and additional underground mining has been proposed that would extend the life of the mine to more than 16 years of operations. The company has received some preliminary approvals by the Michigan Department of Environmental Quality (MDEQ).
The proposed mine has special significance for the Menominee Indian Tribe of Wisconsin because it is their original tribal homeland site that includes prehistoric burial mounds, village sites, raised farming beds, and more. The Menominee reservation is 60 miles southwest of the proposed mine but the tribe’s sacred place of origin is at the mouth of the Menominee River. The tribe fears that sulfide wastes from the proposed mine threatens pollution of the Menominee River and the spawning grounds for one of the largest populations of lake sturgeon in the Lake Michigan basin.
The proposal would require extensive groundwater pumping for many years that will affect the Menominee River and area wetlands. The river itself is further threatened by wastewater discharged into it and potential short and long-term discharges of acid mine drainage from the mine pit and wastes. In addition to lake sturgeon, the Menominee River watershed supports strong populations of small mouth bass, walleye, northern pike and trout. American Rivers named the Menominee River one of our most endangered rivers due to the threats from the proposal and the river’s importance as an aquatic habitat that supports sport fishing and tourism in the river, Green Bay, and Lake Michigan: Green America published a great article about Back Forty background and issues in their magazine.
In February 2017 the Menominee Tribe filed a petition for a contested case hearing on DEQ’s decision to approve the mining permit for the proposed Back Forty mine. “The MDEQ and Aquila Resources Inc. are well aware of the Menominee Indian Tribe’s close cultural connection to this area and our serious concern in regards to our cultural resources and mounds, including our ancestral burial sites located within the impact area of the proposed mine. Despite these valid and well-documented concerns, a full evaluation of the cultural resources and mounds threatened by this project never occurred,” stated Gary Besaw, Menominee Tribal Chairman. Because Michigan is one of only two states that has been delegated authority under the Clean Water Act, the mine application process is subject only to state permits. Michigan DEQ is not required to consult with the tribe or comply with the provisions of the National Historic Preservation Act.
Opposition to the project is strong and organized. Seven local counties, two towns, two cities, dozens of tribal governments and intertribal organizations, environmental, sport fishing and faith-based organizations from both Michigan and Wisconsin have passed resolutions opposing the Back Forty project.
As of spring 2019, Aquila has been “granted” four of four required permits by Michigan’s Dept. of Environmental Quality: Nonferrous Metallic Mineral Mining Permit, Air Use Permit to Install, Pollutant Discharge & Elimination System Permit, and Wetlands Permit. Although the permits have been granted, each has significant conditions attached which have to be met prior to the permit being effective.

Send letters to the principal financial investors in the Back Forty proposed mine letting them know that this project faces growing opposition in Wisconsin and Michigan and does not have a “social license to operate.” As described above, the project faces significant regulatory issues due to its threats to cultural and environmental resources. According to mining risk analysts like Ernst & Young, the fourth greatest risk to mining investors comes from “ignoring community voices and their environmental and public health concerns.”
