Save Oak Flat from Foreign Mining Act
HR 6391, the Save Oak Flat from Foreign Mining Act, repeals Section 3003 of the 2014 National Defense Authorization Act that would have transferred Oak Flat (2,422 acres in Arizona’s Tonto National Forest) to Resolution Copper for mining. The bill withdraws Oak Flat from all public land use, preventing the foreign-owned mining venture (Rio Tinto/BHP) from extracting copper beneath the site for export to China. It directly protects the area, which is a sacred site for Indigenous peoples and a National Register Historic Property, from a mine projected to consume 250 billion gallons of groundwater over 40 years and cause significant land subsidence. The bill halts a process that would have allowed foreign corporations to mine copper from public land without requiring domestic smelting or benefiting U.S. consumers.
