By 2006, the only active uranium mine in Wyoming was the Smith Ranch-Highland in-situ leaching operation in the Powder River Basin, owned by Power Resources, Inc., a subsidiary of Cameco. The mine produced 907 tonnes of yellowcake (uranium oxide concentrate, U 3 O 8) in 2006, making it the leading uranium producer in the United States. [12]
