History

In the late 1860s, silver ore was discovered in the Volcanic Series of Bullion Canyon and Mount Belknap, west of Marysvale in the Tushar Mountains. In 1889, gold was discovered. Then in 1949, uranium was discovered, prompting the United States Atomic Energy Commission to establish an ore purchasing station and field office in Marysvale. The uranium occurs as veins within quartz monzonite, granite and rhyolite, usually in the form of pitchblende, but also as umohoite, which was first identified at Marysvale. The pitchblende has been age dated to the Late Miocene. Total uranium production from the Marysvale area amounted to about 275,000 tons of 0.2 per cent U<sub>2</sub>O<sub>8</sub>.
