Jun 29, 2020 (Therese Pettigrew) - The southern gold showing explored by Graham Bousquet Gold Mines Limited is situated approximately 275 m south of Beartrack Lake. The southern showing occurs in sheared metadiorite and was traced for 18 m with an average width of 0.6 m before becoming overburden covered. Trenching uncovered massive sulphide mineralization with a "fair amount" of sphalerite and galena and assay values of up to 0.75 ounce gold per ton and five to seven percent zinc were reported by Graham Bousquet Gold Mines Ltd. Gold mineralization occurs in a shear zone trending 025 degrees and accompanies pervasive silicification, sericitization and sulphidization which has replaced the host metadiorite. Unlike other gold occurrences in the map area, sulphides are abundant here comprising up to 75 percent of the rock. Pyrite is most abundant with subordinate amounts of sphalerite and chalcopyrite. Although arsenopyrite was not identified in the trench a strong arsenic smell was detected on freshly broken rock surfaces. Galena was reported by Graham Bousquet personnel; however, none was observed by OGS staff member B. Berger. Three grab samples were collected from the trench by Berger and assayed. A sample (031) of siliceous and sericitic schist containing 10 percent cubic pyrite and 5 percent magnetite octahedra returned 8520 ppb gold (0.25 ounce per ton), 5 ppm silver (0.14 ounce per ton) and 400 ppm arsenic when assayed. Sample 032 was composed of approximately 50 to 75 percent sulphides in a silica-tourmaline-chlorite rich matrix and returned 550 ppm copper, 50 ppm lead, 2860 ppm zinc, 1000 ppm arsenic, 31,670 ppb gold (0.92 ounce per ton) and 6 ppm silver (0.17 ounce per ton). Sample 034 which is most abundant in the trench of a sericitic schist with minor silica and up to 30 percent pyrite returned 300 ppb gold, 950 ppm zinc and 350 ppm arsenic. Chorlton (1988) reports that up to 0.3 ounce gold per ton was obtained from samples she collected at the trench. A fourth sample (035) of a chalcopyrite-bearing quartz vein approximately 15 m east of the trench returned 70 ppb gold and 115 ppm copper when assayed (Berger, 1989). DDH BT09 returned 8515 ppb Au over 1 foot (0.3 m) (Assessment report 52F16NW0006). Sampling done in Trench A on the south showing by R. Fairservice in 1989 returned 45,098 ppm Au, 16 ppm Ag, 1600 ppm Cu, and 10,000 ppm Zn from Sample 5 and 80.392 ppm (Assessment report 52F16SW0026). R. Fairservice collected a grab sample in 1989 from the south showing that returned 80.392 ppm (Assessment report 52F16SW2003).
