An U-Cu occurrence located in approximate sec. 21, T41N, Rl7E, G&SRM, about 9.4 km (5.8 miles) NNW of Skeleton Mesa (coordinates of record). The geographic coordinates presented are for the center of sec. 21. This locality is not listed in the USGS MRDS database.
Mineralization is an U-Cu deposit hosted in a conglomerate lens within a Shinarump Member of the Chinle Formation paleochannel. The ore body is 40 feet wide, 200 feet long and averages 4 to 5 feet in thickness. It consists of uraninite, chalcopyrite, chalcocite, bornite and covellite. The beds strike NE and dip 2-3Β° NW on the W flank of the Organ Rock anticline.
Workings include underground openings comprised of a 400 foot sub-level adit with a raise to the ore horizon plus room and pillar mining operations and 41 exploratory drill holes.
Production was 4,131 tons of ore @0.41% U3O8 (1959).
Analysis test results: 0.23% U3O8; 0.15% V2O5; and 16% CaCO3.
