A Cu-Ag-U mine located on 12 claims (Wooley; and the Wooley No. 1 through 11) in the N½ sec. 33, T4S, R13E (Grayback 7.5 minute topo map), about 5 miles NW of Ripsey Hill, about 4.8 miles SE of Grayback (peak), and about 5 miles SW of Kelvin, on BLM-administered land. UTM location is based on the location of the adit on the Wooley claim. Discovered 1895. Last produced 1956. One claim is in the S½ sec. 29. Past owners included the Wooley Mining Co., and the ABC Company. Owned by Leo Wall (1958). Operated by Tom Spargo (1956).
Mineralization is related to E-W trending fissure zones, intersecting NW-striking fault systems, hosted in the Ruin (Oracle) Granite. The ore zone is 609.6 meters long and 274.32 meters wide. Low grade ore in vugs and pores of a stockwork of quartz veinlets. 3 veins 1/8 - 3 inches wide are radioactive. An associated rock unit is rhyodacite. The E-W trending fissure zone runs through the mine. The main zone N83°E. Dikes and fault fissures trend both E-W and NW in nthe area. Alteration is argillic.
Workings include a shaft of 500 feet (152.4 meters) deep; a tunnel of 300 feet (91.44 meters); and several smaller shafts of 10 feet to 100 feet.
