It’s a New Era in Minnesota Mining

Mining is part of Minnesota’s proud past – and can be part of an exciting Minnesota future. PolyMet Mining has proposed building a modern copper-nickel mine in Northeastern Minnesota that will create jobs, boost the economy and sustain our communities – all while meeting state and federal environmental standards put in place to protect our treasured woods, water, air and wildlife.

We have deep roots in Minnesota mining and the expertise, experience and proven, innovative technology to develop the state’s metal deposit safely and responsibly. This is our home, and we’re committed to moving Minnesota mining forward and doing it right.
