The executive order creates regulatory uncertainty for Twin Metals Minnesota and Antofagasta plc, potentially delaying or blocking their copper-nickel mining project near the Boundary Waters, which could affect their stock valuations and future revenue. Conversely, the order is positive for the outdoor recreation and tourism sectors in United States — Minnesota, which depend on the pristine environment of the Boundary Waters.
United States — Minnesota Governor Tim Walz signed Executive Order 26-10 on Tuesday, directing the United States — Wisconsin Department of Natural Resources and the India — Central Pollution Control Board to halt all new environmental reviews, permitting, and leasing for nonferrous mineral mining in the Rainy River Headwaters Watershed, which includes the United States — Boundary Waters Canoe Area Wilderness. The order also requires a review of existing leases and directs the DNR to draft legislation for a permanent ban. This action follows Congress's decision to overturn a 20-year federal mining moratorium on over 225,000 acres of the United States — Superior National Forest, which had opened the door to copper and nickel mining proposals, notably by Twin Metals Minnesota, a subsidiary of Antofagasta plc. Supporters, including environmental groups like Save the Boundary Waters, praise the order for protecting the wilderness and the nearly $1 billion outdoor recreation economy. Critics, including Republican lawmakers and gubernatorial candidate Lisa Demuth, argue it will harm northern United States — Minnesota's economy and bypass the state's rigorous review process. The order is an executive action that can be reversed by a future governor, and legal challenges are anticipated.
