US HB6391

Repeals Section 3003 of the FY2015 National Defense Authorization Act (Public Law 113-291), which required the Forest Service to transfer Oak Flat to Resolution Copper Mining within 60 days of a Final Environmental Impact Statement

Withdraws approximately 2,422 acres of Oak Flat in Arizona's Tonto National Forest from all mining claims, mineral leasing, and public land disposal

Resolution Copper is a joint venture between Rio Tinto (55%) and BHP (45%), with Rio Tinto's largest shareholder being Chinalco, a Chinese state-owned company holding 14.56% ownership

The proposed mine would extract copper one mile beneath the surface, creating a crater 2 miles wide and over 1,000 feet deep, consuming over 250 billion gallons of groundwater over 40 years

Oak Flat is listed on the National Register of Historic Places as a Traditional Cultural Property and is ancestral homeland to American Indians who were forcibly removed from the area in the 1880s
