A former U-V occurrence/mine located in approximate secs. 31 & 32, T39N, R29E, G&SRM, in the SW Carrizo Mountains. The geographic coordinates presented are approximate to the center of sec. 32. There is no record of a sec. 30 or 31 in this T&R.

Mineralization is a U-V deposit with tyuyamunite-type ore that occurs as pods and lenses hosted in sandstone of the median horizon of the Salt Wash Member, Morrison Formation.

Workings include underground openings comprised of a drift (sic).

Production was 147 tons @0.18% U3O8 and 1.59% V2O5.
