The lifting of the mining ban by Donald Trump is a positive development for Antofagasta plc and its subsidiary Twin Metals Minnesota, potentially opening up new mineral supply chains. However, the path forward for Twin Metals Minnesota is still uncertain due to ongoing legal challenges and the rigorous permitting process involving the United States — Wisconsin Department of Natural Resources and potential opposition from Amy Klobuchar and environmental groups.

Donald Trump has lifted a federal ban on mining near Minnesota's Boundary Waters Canoe Area Wilderness, reversing a 20-year moratorium imposed by Joe Biden's administration in 2023. This decision clears the way for Twin Metals Minnesota, a subsidiary of Antofagasta plc, to begin applying for permits to mine copper, nickel, and other precious metals in the Superior National Forest. Environmentalists and groups like Save the Boundary Waters fear this move sets a dangerous precedent for public lands and could contaminate the wilderness area. Twin Metals Minnesota still faces significant hurdles, including reestablishing its right to mine after the United States — United States Department of the Interior terminated its federal leases in 2022, a decision the company is appealing. Additionally, Twin Metals Minnesota must secure various state permits from the United States — Wisconsin Department of Natural Resources and could face legal challenges from environmental groups and tribes. Canadian officials may also raise concerns about potential cross-border pollution.
