Numerous openings located 1 mile south of Greaterville, in the flat, dissected area at the head of Harshaw Gulch.
Mineralization involves a steep southeastward-dipping fault-breccia contact of granite porphyry intruded into the red silicified shale. Disseminated pyrite is evident which is locally replaced by pseudomorphic hematite. Very rich pockets of gold were reported at surface but do not persist with depth.
