Aug 15, 2019 (Therese Pettigrew) - Zinc mineralization is found on the south shore of Southorn Lake near the west end of the lake. Pyrite, pyrrhotite and visible sphalerite, and minor galena occur in a silicified shear zone in epidotized mafic metavolcanics. The mineralized zone is about 20 feet wide and trends N70E, for about 80 feet. A grab sample taken from this showing by Hudec (1964) gave an assay of 1.88% zinc. A grab sample taken by OGS staff in 1967 and submitted to the Laboratory Branch on assay contained 1.13% zinc, 0.21% lead and 0.40 oz./ton of silver.
