About this project
Poly Met Mining, Corp. (PolyMet) is proposing 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 Minnesota DNR's review of PolyMet's NorthMet proposal has followed a rigorous environmental review process and extensive evaluation of the company's permit applications, beginning in 2005. This included careful review of more than 22,000 public comments on draft permits in 2017 and early 2018.
