MRDS database Dep. ID file #10039903, MRDS ID #M051083.
A Cu occurrence/prospect with surface and underground workings located in sec. 32, T11S, R8E.
Mineralization is ore hosted in quartz monzonite. Chrysocolla occurs on fractures with boxwork pyrite-chalcocite. Drill hole tailings nearby have pyrite with light chalcocite replacement and perhaps some quartz-sericite alteration. Alteration includes quartz-sericite-pyrite.
Workings include a shaft & prospect.
