Minnesota Governor Tim Walz has issued an executive order to slow down mining efforts in the Boundary Waters wilderness area along the state's border with Canada. The order, which would expire in April unless adopted by the next governor, prohibits Minnesota regulators from participating in federal environmental reviews of nonferrous mining in the Rainy River watershed and from conducting environmental reviews or permitting work on mining proposals. This move comes after a 2023 federal moratorium on mining was lifted in April. Walz's order has been criticized by Republican U.S. Rep. Pete Stauber, who called it an "outright war on northern Minnesota".

Story summary
Minnesota Governor Tim Walz has vowed to slow down mining efforts in the Boundary Waters Canoe Area Wilderness, a pristine wilderness area that stretches for about 240 kilometres along Minnesota's border with Canada. The decision comes after the Trump administration lifted a federal ban on mining in the area four months ago, allowing projects like Twin Metals Minnesota LLC's proposed copper and nickel mine to move forward. Walz, a Democrat, has called the area "sacred" and said it is his duty as Minnesotans to ensure that it remains wild and unharmed. However, the executive order is only temporary, as it would expire in April, 90 days after he leaves office, allowing a future governor to adopt or reject it. There are currently no "shovel-ready" mining projects in the area, but Twin Metals has been seeking to mine for precious metals since 2019.
