Hudbay wavers in its commitment that Rosemont/Copper World will produce copper for U.S. markets

Toronto-based Hudbay Minerals Inc. is quietly backing away from its public relations claim that the proposed Rosemont/Copper World mining complex in the Santa Rita Mountains south of Tucson will provide copper for U.S. domestic markets and reduce energy consumption associated with exporting copper overseas.

Last summer, the company began touting its commitment that Rosemont/Copper World will produce copper for the U.S. renewable energy economy when it released a technical report stating it would use an expensive “sulfide leaching” technology to produce finished copper extracted from sulfide ore on-site.
