The US Senate voted 50–49 to repeal the Biden-era withdrawal of 225,000 acres of Minnesota's Superior National Forest from mining, clearing a federal path for Twin Metals' copper-nickel project in the Duluth Complex. Chile's government under President Kast is targeting 6 million metric tonnes of annual copper output in 4–5 years, well ahead of prior projections, with US investors showing strong interest. And Perpetua Resources' $2.7 billion Export-Import Bank loan for Idaho's Stibnite Gold Project — which would be the only US mined source of antimony — is in its final 25-day Congressional review window ahead of an expected final board vote around April 25.
