Our goal is to meet the world’s growing need for critical and strategic metals — with safety as the number one priority.
We’re focused on designing, constructing and operating an underground copper, nickel, cobalt and platinum group metals mine, located about nine miles southeast of Ely and 11 miles northeast of Babbitt. We’re targeting the minerals within the Maturi deposit, which is part of the Duluth Complex geologic formation.
Our project will bring more than 750 direct full-time jobs and 1,500 new spinoff jobs to the residents of northeast Minnesota – an unprecedented economic impact that has the potential to revitalize an entire region.
For more than a decade, we’ve been carefully planning how to sustainably mine these metals. Here’s a brief look at our history:
The largest hydrogeological study in the history of northeast Minnesota began for the legacy Duluth Metals Limited project.
Following Duluth Metals Limited’s identification of strategic metals deposits, it formed a partnership with Antofagasta PLC. Together, they founded Twin Metals Minnesota.
Twin Metals Minnesota completed and opened its operational headquarters in Ely.
Twin Metals Minnesota unveiled the nearly 17,000-square-foot Core Storage Facility at its operational headquarters.
Antofagasta PLC purchased Duluth Metals Limited in a friendly acquisition.
Twin Metals Minnesota announced it will use the environmentally friendly dry stack tailings storage method.
Twin Metals Minnesota signed a Project Labor Agreement with the Iron Range Building and Construction Trades Council.
Twin Metals Minnesota submitted its mine plan to state and federal agencies, kicking off a multi-year scoping and environmental review process that will thoroughly evaluate the proposal.
Twin Metals Minnesota is a wholly owned subsidiary of Antofagasta PLC. 18 Minnesota-based employees support two offices in Ely and St. Paul.
We’ve been conducting a variety of hydrogeological and environmental studies for more than a decade. Data from these studies is being used to evaluate the potential impact of our project and will be essential throughout the formal Environmental Impact Statement process conducted by state and federal agencies.
Environmental regulations tightly restrict how mines are designed and operated.
State and federal agencies require strict adherence to regulations surrounding environmental issues, including surface water and groundwater quality, threatened and endangered species, air quality, plant life, wetlands and more. If our project doesn’t meet or exceed environmental standards, it won’t be authorized
to move forward.
