In the late 1860s, silver [[ore]] was discovered in the [[volcanic|Volcanic Series]] of Bullion Canyon and [[Mount Belknap (Utah)|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 [[vein (geology)|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 [[triuranium octoxide|U<sub>2</sub>O<sub>8</sub>]].<ref name="Full1968">{{cite book |last1=Kerr |first1=Paul |editor1-last=Ridge |editor1-first=John |title=The Marysvale Utah, Uranium Deposits, in Ore deposits of the United States, 1933-1967 |date=1968 |publisher=The American Institute of Mining, Metallurgical, and Petroleum engineers, Inc. |location=New York |pages=1020–1042}}</ref>
