The SILVERSIDE occurrence is located on lower valley sides west of Tommy Creek, approximately 6.5 kilometres south-southwest of the creek mouth on Carpenter Lake. The showing is 17 kilometres east of Bralorne and 46 kilometres west-northwest of Lillooet, B.C.
The area is underlain by Mississippian to Jurassic Bridge River Complex (Group) sediments consisting of cherty and slatey argillites, thinly bedded cherts, biotite-bearing metasediments, sandstone and minor recrystallized limestone. The strata strike north-northwest with near vertical dips. Volcanics are intercalated with the sediments and dikes cutting the sediments also occur.
The main quartz vein averages less than 1 metre in width and is exposed for 250 metres, dipping 65 degrees west. The quartz is white or glassy with limonitic staining. The main vein has 3 to 4 per cent pyrite and arsenopyrite, 2 to 3 per cent galena and possibly stibnite. Smaller lenticular quartz-calcite-siderite veins also occur but are un-mineralized. Wallrock alteration, limited in extent and poorly developed, consists of calcite and epidote in the volcanic rocks. A second, narrower, lens-shaped vein, with a maximum width of approximately 0.25 metre, hosts massive sulphide mineralization consisting of pyrite and chalcopyrite with lesser sphalerite and trace bornite.
During 1985 through 1988, Levon Resources Ltd. completed ground and airborne geophysical surveys, geochemical sampling and geological mapping on the area as the Silverside claim. A grab sample (C1242) assayed 72 grams per tonne silver, 0.23 per cent lead and 0.3 gram per tonne gold. A 0.25- metre chip sample (C3828) assayed 9.62 per cent copper, 1.77 per cent zinc and 48 grams per tonne silver, while a rock sample (C3829) yielded 1.03 grams per tonne gold (Assessment Report 14670). In 1995, a program of rock and soil sampling was completed by Levon Resources.
In 2021, Pan Pacific Resource Investments Inc. conducted programs of airborne LiDAR, magnetometer and radiometric surveys, and prospecting and rock sampling over the area encompassing the Silverside showing (Assessment Report 40023). This included other mineral occurrence areas nearby; Bristol, Benboe, Silverside Extension and Bristol 11.
