We’re here to help you learn more about modern mining, the science and technology behind the mine if you will. Part of responsible mining includes being transparent with who we are, what we’re doing and why.
The facts about mining and our project.
Mining has dramatically changed over the years. What may have been true in the past is not necessarily true today. Especially with modern mining and advanced technology.
Our plan of operation
Twin Metals Minnesota is proud to formally propose its world-class, 21st century underground copper, nickel, cobalt and platinum group metals mining project. The company is dedicated to building, operating, and closing a mine that meets or exceeds all state and federal environmental standards.
Meet the Wolf Gang.
They’re fun, they’re furry, they’re friendly. It’s the Wolf Gang, howling out for Twin Metals.

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.
Backfill is material used to refill an excavated area of the mine. Approximately half of the tailings from the TMM Project will be stored as permanent cemented backfill in the underground mine.
Concentrates are the end product of the Twin Metals project. These concentrates are sold on a global market and contain the minerals that have been separated from rock in the mine.
