Uranium prospects located in secs. 28 & 32, T.7S., R18W & secs. 6 & 7, 1, 2, 10, 12 & 35, T8S, T19W.

Mineralization is traces of uranophane, autunite, pyromorphite, carnotite, and unidentified uranium minerals in Tertiary volcanic tuffs and ash, opalized mudstone, and other lacustrine sediments. Probable origin of the uranium was tuffaceous volcanic rhyolite. Specific species have not been attributed to specific prospects.

Field explorations only.
