Jun 22, 2018 (Therese Pettigrew) - Three zones have been mined. Of the two that lie within a unit of coarse-grained gneiss with iron formation, which strikes NS and dips 20-25E, the north or No. 1 zone is up to 7.6 m thick and consists of disseminated and massive pyrrhotite and pyrite with chalcopyrite, sphalerite and galena in quartz or replacing amphibole and biotite in the host rock. Wallrock alteration is slight. The second or No. 2 zone, located 213.4 m S of the No. 1 zone, is similarly mineralized. It strikes NW and dips 25NE. It attains a strike length of 115.8 m and ranges in width from 0.6 to 8.2 m. Wallrock alteration includes epidotization and silicification. The No. 3 deposit, consisting of zones 3A and 3B, is located 487.7 m SE of the No. 2 zone. It occurs in iron formation and is mineralized with pyrrhotite, pyrite, sphalerite and chalcopyrite. The zone strikes N30W, dips 25-45NE and averages 7.6 m in thickness (Shklanka, 1969).
