Southern Utah: Uranium & the Atomic Frontier
Lisbon Valley, UtahUranium
Charlie Steen's uranium country: the 1952 discovery that set off America's atomic boom, and the untested half of the valley being hunted again.
The History
In 1952, a broke geologist named Charlie Steen drilled into the Mi Vida deposit in Lisbon Valley, in San Juan County, and touched off the great American uranium boom. The valley's west flank went on to produce roughly 78 million pounds of U3O8. But the Lisbon Valley anticline has two sides: the same host rock dives deeper on the east flank, and that half was never really tested. American Atomics is testing it now — its Big Indian Project holds 217 claims on the east flank, hunting what the company believes may be the mirror of Steen's discovery, a hypothesis the drill still has to prove. Just over the Colorado line, its Blue Street Complex works past-producing ground in Paradox Valley, and down the road at Blanding, Energy Fuels' White Mesa mill — the only operating hard-rock uranium mill in America — anchors the processing end of the story.
