Mineralization is hosted in dolomite. Controls for ore emplacement included a breccia zone. Cobalt oxide was replacing dolomite country rock along a local fault, forming dendrites. Associated rocks include Paleocene granite. Local rocks include dolomite, limestone, and minor amounts of sandstone and quartzite.

Regional geologic structures include large-scale overthrusts. Local fault occurs W of the shaft.

Workings include underground openings with a length of 152.4 meters and an overall depth of 33.53 meters. The main workings are 2 shafts 800 feet apart.
