Oct 30, 2020 (Sheree Hinz) - The Temagami-Lorraine occurrence is hosted by varied textured Nipissing diabase which has undergone extensive local alteration by hydrothermal solutions adjacent to the veins. Adjacent and 150 m to the south of the shaft are Archean felsic volcanic rocks. Quartz vein material fills a 4-inch fracture in a diabase dike trending S 20 degrees E.

Oct 30, 2020 (Sheree Hinz) - Sulphides and arsenides are present in the quartz vein and an assay value of 1.08 oz. Au/ton was obtained. The vertical 10 cm wide, southwest-trending calcite-quartz vein contains cobaltite, erythrite (cobalt bloom), arsenopyrite, pyrite and chalcopyrite. Samples taken in 1989 (R271) indicated values of 1.07 ounce per ton Au, 20 ppm Ag, 3050 ppm Cu and 2.14% Co.
