About the project

Poly Met Mining, Inc. (PolyMet) is proposing to develop a mine and associated processing facilities for the extraction of copper, nickel, and platinum group elements (PGE) in northeastern Minnesota. The mine would be the first of its kind in the state. The proposed NorthMet Mining Project would be located in the St. Louis River watershed on the eastern edge of the Mesabi Iron Range, about 6 miles south of Babbitt.

The proposed NorthMet Mining Project includes:

Environmental Review Process

Prior to the current permitting phase, the proposed NorthMet Mining Project went through an extensive environmental review process. PolyMet submitted its initial project proposal to the Department of Natural Resources (DNR) in February 2005. In accordance with state and federal laws, an Environmental Impact Statement (EIS) was prepared under the leadership of the DNR, U.S. Army Corps of Engineers (USACE), and the U.S. Forest Service (USFS). The Final EIS was deemed adequate by the DNR in March 2016 marking the end of the state’s environmental review process. EIS decisions for the USACE and USFS are still pending.
