The Twin Metals Minnesota (TMM) Project is focused on designing, constructing and operating an underground copper, nickel, cobalt and platinum group metals mine, and is committed to doing so in an environmentally responsible way. Located approximately nine miles southeast of the city of Ely, Minnesota, and 11 miles northeast of the city of Babbitt, Minnesota, the TMM Project targets the valuable minerals within the Maturi deposit, part of the Duluth Complex geologic formation.

The TMM Project represents an extraordinary opportunity for economic growth and job creation regionally and statewide. Construction will generate several million labor hours, on par with the number of construction and related professional jobs created by projects such as U.S. Bank Stadium and Target Field in the Twin Cities. Once operational, TMM expects to directly employ more than 750 people long term in northeastern Minnesota and to create an estimated 1,500 spinoff jobs in other industries.

The TMM Project is located in northeast Minnesota. The mine would be located within the Maturi deposit, which is located outside the Boundary Waters Canoe Area Wilderness and approximately nine miles southeast of the city of Ely, Minnesota, and 11 miles northeast of the city of Babbitt, Minnesota.
