St. Louis group, Muggins Mountains uranium prospects, Muggins District, Muggins Mts, Yuma Co., Arizona, USA

Latitude: 32°46'5"N
Longitude: 114°11'6"W
An U deposit/prospect located in the center sec. 2, T8S, R19W, on land of unknown status. Mr. Joe Baker et al had unspecified involvement here (1955).

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 this or any other specific prospect.

Field explorations only.
