In December 2014, the United States Congress passed, and President Obama signed the 2015 National Defense Authorization Act, which included the provisions of the stalled Southeast Arizona Land Exchange and Conservation Act. The Act cleared the way for the land swap in which Resolution would receive 2,422 acres of National Forest land in exchange for deeding to the federal government 5,344 acres of private land. The mine would destroy an area set aside in 1955 by President Dwight D. Eisenhower which is sacred to the San Carlos Apache Indian Reservation. Both the Oak Flat Campground, an area dotted with petroglyphs and historic and prehistoric sites, and the steep cliffs at Apache Leap would be affected.
