A Cu occurrences/prospects located in sec. 21, T14S, R12E.

Mineralization is a vein deposit. The ore zone is 370 meters long (length given is the strike length of the fault in the Brown Mtn Quadrangle only), 1 meter wide, strikes S70E and dips 55S. Alteration is quartz-sericite-pyrite; pyrite-pyrrhotite gossan; and local scorodite (?) boxworks. Ore control was a reverse fault extending from here to the SE for about 1 km. The shear zone has abundant limonite gossan and minor Cu-silicate crusts. Local arkose beds show quartz-sericite alteration. Massive pyrrhotite on the dump of the western shaft has possible minor associated chalcopyrite + chalcocite.

Workings include two prospect shafts 90 meters apart. The western shaft, on prospect 101-6, is filled with trash.The eastern shaft, on prospect 101-10, is open, shows structure, is 3 meters deep, opening to an E-W tunnel. Immediately downhill to the N is a tunnel, and immediately downhill to the NW is an incline showing the shear zone given above.
