Additional help was provided by NRRI (Natural Resources Research Institute) and MGS (Minnnesota Geological Survey). GIS Data sources used are as followed: Mining features, Mineral Deposits, and State Metallic Mineral Leases from the MN DNR Division of Lands and Minerals. Bedrock Geology features are from the MGS 2010 version (1:500,000). Roads and Railroads from Mn/DOT (MN Department of Transportation); Political features, County Boundaries, Public Land Survey features, and Cities from the MN DNR; Lakes shown are greater than 100 acres and were taken from the MN DNR; Shaded relief created from a hybrid of 5- Meter, 10-Meter, and 30-Meter Digital Elevation Models.

This graphic shows the locations of the deposits, the state mineral leases held by six companies and notes where resource estimates [NI 43-101 compliant] were completed. Polymet is the first company to propose a mine in this district, and the environmental review process is in progress.
