TWIN METALS STATEMENT ON FEDERAL GOVERNMENT’S ACTION TO INITIATE MINERAL WITHDRAWAL STUDY

St. Paul, Minn., October 20, 2021 - Twin Metals Minnesota is deeply disappointed with the federal government's action to initiate a mineral withdrawal study yet again on nearly 230,000 acres of land in northeast Minnesota, which sits on top of the world's largest known undeveloped copper-nickel deposit. We are working to determine the best path forward to continue advancing our proposed world-class underground copper, nickel, cobalt and platinum group metals mine. We are firmly dedicated to the communities of northeast Minnesota and to advancing a sustainable mining project that will bring much-needed economic growth to our region, in addition to the opportunity to responsibly develop the critical minerals needed for our global efforts in combatting the climate crisis. Twin Metals' mineral rights span 11 presidential administrations, and we remain steadfast in upholding those rights and advancing our model mining project.

The TMM project brings the promise of significant long-term jobs and environmentally responsible economic development for generations in Minnesota.
