In Range: Copper Mining in Minnesota

For more than 130 years, the Mesabi Iron Range has been the major source of iron ore for the nation’s steel industry, supplying the raw materials that helped build industrial America. In the 1940s copper was discovered near the eastern end of the Iron Range on the northern margin of a massive geologic formation known as the Duluth Complex. Since then, improvements in processing technology made mining the Duluth Complex possible. Today, we have the ability to economically recover the base metals of copper, nickel and cobalt and precious metals including platinum, palladium, gold and silver from the Duluth Complex.

We are working hard to become the first Minnesota mining company to commercially produce these metals, further solidifying the state’s position as a supplier of critical raw materials for the nation and ushering in a new era of economic prosperity on the East Range.
