In 1957 Steen opened the Uranium Reduction Company, the nation's first large independent uranium mill, in Moab. Sold to Floyd Odlum's Atlas Corporation in 1962, the facility shut down in 1984.
By 1955 there were approximately 800 mines producing high-trade ore on the Colorado Plateau. Utah alone had produced approximately nine million tons of ore valued at $25 million by the end of 1962.
