Geology:
The deposit is located in an irregular shear zone striking N20E for about 1000 feet in mafic metavolcanics. The shear zone reportedly had a width of 50 feet. The deposit may be symmetrically zoned with a central zone of arsenopyrite and carbonate veinlets passing outwards into a zone of pyrrhotite, then pyrrhotite with carbonate veinlets and finally an outer zone of country rock intersected by narrow veinlets of carbonate.
