The DS 336 showing is about 500 metres northwest of the Stockwork or Crystal showing (093A 126) near the divide between the headwaters of Little Snowshoe and French Snowshoe creeks, about 22 kilometres south of Barkerville.

The showing is described as quartz lenses containing galena, pyrite and arsenopyrite and occurs in metasedimentary rocks (quartzite) of the Upper Proterozoic-Paleozoic Snowshoe Group. Although this occurrence was documented in the 1980s, it is within a cluster of precious metal bearing quartz veins that was initially recognized in the 1800s (Geological Survey of Canada Map 369; Bulletin 34). A sample from the DS 336 showing analyzed 11.3 grams per tonne silver, 0.11 gram per tonne gold and 2.86 per cent lead (Assessment Report 13663).

In 1984, Suncor Inc. took 1004 soil samples and 7 rock samples on their Yanks Peak property grid.
