A surface Cu prospect located in the N½ sec. 7, T8S, R19E (Oak Grove Canyon 7.5 minute topo map), 2 miles ENE of Copper Creek in the Galiuro Mountains. Discovered by Fred Coats and Leo Cook in 1957.
Mineralization is a tabular ore body 0.03 meters thick, hosted in Galiuro Volcanics Andesite. The ore zone strikes WNW and dips 80S. Chrysocolla and malachite form films on fracture surfaces; altered chalcocite (?). Ore control was fractures.
Area structures include block faulting, tending NNW. Regional trends: minor Cretaceous E- and NE-trending folds and major Post-Cretaceous NNW-trending faults. Late Tertiary uplift and faulting.
There are probably no workings.
