Senate votes 50-49 to repeal Boundary Waters mining ban, sending copper/nickel development to Trump
The Senate voted 50-49 Thursday to overturn the 20-year 225,378-acre mineral withdrawal around Minnesota's
Analysis
The 50-49 margin, with Collins and Tillis as the only Republican defectors, was a single vote from killing the resolution and leaving Antofagasta's $2B+ Twin Metals project dormant for another decade. The genuine precedent, per converging coverage, is not the copper-nickel access but the permanent bar on future presidential withdrawals: a Congressional resolution constraining executive public-land authority that, applied sequentially to other mineral tracts, compounds into a material shift in federal multiple-use doctrine. The vote almost certainly advances near-shoring of nickel and copper supply away from Indonesian and Chilean choke points, though Antofagasta's sulfide tailings record in Chile is a real liability on the upstream-of-wilderness siting. Litigation under NEPA and the Clean Water Act will very likely stall any actual ore-hauling for 24–36 months, making Thursday's vote a political event more than an extractive one in any near-term window.
