A surface Cu-Mo prospect located in the NW¼ sec. 24, T.1S., R.14E.
Mineralization is an irregular ore body hosted in Pinal Schist. Associated rock units are the Madera Diorite and Schultze Granite.Alteration is oxidized and leached capping of pyrite and copper sulfides.
Geologically this deposit lies in the Pinal Schist between the Schultze Granite to the north and the Madera diorite to the south. It is an isthmus-like outcrop of Pinal Schist which is much of the area extending from the Ellis vein at the east to the west boundary of secs. 14 & 23, T.1S., R. 14E., and has the characteristics of 'capping' formed by oxidation and leaching of included grains and veinlets of metallic sulfides. The boxwork and residual limonite indicate a great preponderence of pyrite, but the former presence of some copper sulfides is proved by copper stains in a few places where veinlets are especially large or abundant.
Workings include 5 drill holes down to and through rock containing disseminated sulfides and 'proto' ore.
