Leaders of Occupy Oak Flat say they won't give up until the U.S. government repeals the Southeast Arizona Land Exchange. The San Carlos Apache Tribe, leading a three-week protest at the Oak Flat Campground, vows to remain there until the federal government bends. The controversial exchange gave Australian-British mining company Resolution Copper (a subsidiary of the largest mining company in the world, Rio Tinto) access to a vast underground copper reserve under Oak Flat. The deal trades 2,400 acres of previously federally protected land for 5,300 acres of company property. The land exchange was attached to the 2015 United States National Defense Authorization Act as a midnight rider after it failed to pass as a stand-alone bill multiple times during the last decade.
