President Obama signed into law the National Defense Authorization Ac, which includes a provision for the land swap (Southeast Arizona Land Exchange and Conservation Act) needed for the underground Resolution Copper mine to move forward.
Resolution said, "The heart of the legislation is the exchange of 2,400 acres of federally owned land above the copper deposit for 5,300 acres of land owned by Resolution Copper composed of valuable recreational, conservation and culturally significant land throughout Arizona." A story on Mineweb.com reported that "The high-value
conservations land were identified through the input from the U.S.
Forest Service, the Bureau of Land Management, the Audubon Society and
others. The swap consolidates ownership of the land where the mine will
be developed and operated."
Resolution Copper provided this summary of the parcels involved in the land exchange:
