PolyMet Mining

Our Business

Products and uses

PolyMet will produce a number of valuable metals used in our daily lives, including copper, nickel, cobalt, platinum, palladium, and gold.

copper nickel cobalt platinum palladium gold

While there is significant domestic demand, the United States has very few mines producing these metals. There are no domestic nickel or cobalt mines, and the U.S. typically imports 40% of the copper it consumes and between 80% and 95% of the platinum, palladium and gold.

While mining in the United States is strictly regulated, many countries exporting these metals have little or no environmental regulation. Pollution from these foreign mines not only harms the local environment, it also frequently becomes airborne and falls within U.S. boundaries. PolyMet will meet the strict Federal and State environmental regulations.

PolyMet will annually produce approximately:
