...Utah, he hunts rocks. One day, while prospecting around the sage and cedar-covered mountains northeast of Marysvale, he found some strange yellow-colored rocks strewn over a surface of about 60 acres. Segmiller thought they might be valuable, so he staked a claim and called the Vanadium Corp. of America. When it inspected the claim; it got pretty excited and leased the land from Segmiller. The yellow rocks were autunite, a uranium-bearing ore, and the strike looked like the most promising yet made...

At 26 pounds of U-235 per atom bomb (a current guess), this early production could have yielded theoretically enough "fissionable material" for four bombs. The Tyuya Muyun mine was still producing in 1936, when it (and some radioactive waters near Ukhta) yielded enough radium...
