Further to the Energy Fuels information, "The White Mesa Mill is the only fully-licensed andoperating conventional uranium mill in the United States, and only one of three in North America."

Hence, the only leaching of uranium ore in the U.S. is at Blanding, Utah, meaning ALL ore produced form the Arizona Strip is shipped there, including what will be coming from NPSP.
But none of this will, of course, shut up a committed basher.
