Commodities (Major) - Uranium, Vanadium
Development Status: Producer

Although some reports place the mines of the School Section claims and the Cactus Rat mine group in the basal conglomerate sandy beds of the Brushy Basin Member (just above the Salt Wash Member), Stokes (1952) concluded that they are in the conglomerate at the top of the Salt Wash Member.

Unnamed minerals include a uranyl vanadate that may correspond to synthetic Na(UO2)(VO4)(H2O)2 (PDF 04-018-9705), the possible Na analogue of finchite, an Na-MgAl decavanadate similar to pascoite and a phase somewhat similar to sabugalite and threadgoldite.
