The exact location of the S.D. showing is not known. It is assumed be on the S.D. claims (Lots 4560-4563), on the south side of Bitter Creek, about 5.5 kilometres east-southeast of the confluence of Bitter Creek with the Bear River.

The area is underlain by the Tertiary(?) Bitter Creek quartz monzonite pluton that intrudes gently dipping sediments of the Middle Jurassic Salmon River Formation (Hazelton Group). Because of the uncertainty of the exact location of the showing, the nature of the hostrocks are unknown. Several mineralized quartz veins are reported to be on the S.D. claims (Property File - Little, 1935).

The main (No. 1) vein trends approximately northwest, parallel to Cable Creek, and dips southwest. It consists of quartz mineralized with chalcopyrite(?). In 1935, a chip(?) sample was collected about 60 metres south of the south end of the No. 1 vein. The sample assayed 21.3 grams per tonne gold, 2.0 per cent copper and 137.1 grams per tonne silver across 1.2 metres (Property File - Little, 1935). Three other small veins, carrying lead and zinc values, are approximately parallel to the No. 1 vein (Property File - Little, 1935).

The S.D. claims, owned by Erickson, were first reported in 1925. That year they were acquired by Stewart Central Mines Limited which had been incorporated the previous year. Two veins were reported on the property at that time. No work other than opencutting was reported. The claims were Crown granted to the company in 1929. The company name was changed to Victor Gold Mines Limited in 1934. The following year a crosscut tunnel was reported, but the location is not given. At least four veins were reported that year. In 1973, the property was owned by Stewart Development Ltd. That year Totem Uranium Ltd. assigned a 90 per cent interest in an option on the property to Whipsaw Mines Ltd. No further work has been reported.
