Senate reverses Boundary Waters mining ban, unlocking Chilean-backed copper project
The Senate narrowly voted 50-49 to overturn Biden’s 20-year mining moratorium in Minnesota’s Superior National Forest via the Congressional Review Act, clearing the way for Twin Metals Minnesota—an Antofagasta subsidiary—to restart plans to mine copper, nickel, cobalt and platinum near the Boundary Waters. Democrats and environmentalists warn of water pollution, while supporters hail a win for mining and jobs; the measure has House support and is headed to President Trump for signature.
