Status | Applications Withdrawn - On March 24, 2015, Gogebic Taconite officially withdrew their application for a proposed mine in Northern Wisconsin. Click here to read their letter to the Wisconsin DNR.
Location | The Penokee Hills, in Iron & Ashland Counties, near Mellen, WI
Type of Mine | open pit – taconite
Estimated Mine Life | 35 years (phase 1)
Anticipated Output | 24 million tons ore/year, 10 million tons waste rock/year (www.wisconsin.sierraclub.org/documents/GLIFWC_TaconiteReport_2011.pdf)
- Phase 1 of the project would be approximately 4 miles long by 1/2 mile wide. Additional phases could cover a 21 mile stretch within the range.
- The ore deposit’s overburden contains pyrite, a sulfide mineral that could cause acid mine drainage. Other potential contaminants common in taconite mining include mercury, arsenic, other heavy metals and sulfates
- Blasting releases dust and blasting product residue that pollutes the air. The presence of grunerite (a form of asbestos) in the area of the proposed mine has heightened these concerns.
- The proposed site is at the headwaters of the Bad River. More than 20 additional rivers and streams also flow from the area. These waterways flow into the Bad River watershed, the Kakagon and Bad River sloughs and ultimately into Lake Superior, so any contaminants would end up in the watershed and the Great Lakes system.
- Both groundwater and surface water levels will be affected by the constant pumping required to operate the 1,000 foot deep ore pit. View the INFOgraphic.
- The Bad River Reservation, located downstream from the proposed site, is home to the 16,000 acre Kakagon and Bad River Sloughs. The sloughs are home to culturally and economically important wild rice beds. These rice beds are very sensitive to fluctuating water levels and sulfate contamination.
- The area provides the drinking water source for Ashland, Mellen, Highbridge, Marengo, Odanah, and Upson, making water quantity and quality very important.
- Public access to Managed Forest Land surrounding the proposed mine site is now restricted. View the Wisconsin DNR map of the closed lands here.

A Penokees Primer | Get to know the Penokee Hills of Wisconsin. Mining interests are hoping to blast an open pit taconite mine into this water-rich landscape that includes the headwaters of the Bad River. And Wisconsin legislators just passed a bill that exempts iron mining from many environmental protections.
