PolyMet proposes to develop an open-pit mine and processing facilities for the extraction of copper, nickel and platinum elements, with an estimated 20-year lifespan for mine operations. The proposed mine would be located in the St. Louis River watershed on the eastern edge of the Mesabi Iron Range, about 6 miles south of Babbitt and about 1 mile south of the existing iron-ore Northshore Mine. Processing of the ore would take place at a former industrial site, the LTV steel plant in Hoyt Lakes.
