The B.S. 3 showing is located adjacent to the Lumby (Chaput) deposit (082LSE006), about 1.7 kilometres east of Lumby.
In 1987, Zicton Gold acquired the claim and conducted geological and geophysical surveys. In 1988, a geophysical survey was conducted. In 1989, a diamond drillhole and sampling were completed. In 1991, geological and VLF-EM surveys and one diamond drillhole were completed. In 1990, a diamond drillhole at the northeastern corner of B.S. 3 was completed. In 1992, geological mapping and geophysical surveys were conducted on the B.S. 3 and Hol 1-4 claims. In 1993, geological mapping and rock and soil sampling were completed on these claims.
The area is underlain by Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks. These comprise primarily argillite and tuff but include siltstone, limestone, shale, conglomerate and schist.
Veins occur in metasedimentary rocks near the highly altered contact with granodiorite.
An outcrop, 200 metres long, is exposed in a roadcut. The eastern 100 metre portion of the outcrop is on the B.S. 3 claim. The outcrop consists of bleached, sericitized, calcareous metasediments cut by three pyritic, sulphide-bearing quartz veins (Samples D-92-10, 11, 12). Altered granodiorite occurs at the extreme east end of the outcrop.
The quartz veins contain 1 to 2 per cent cubic pyrite (locally up to 10 per cent) with up to 1 per cent galena, up to 1 per cent sphalerite, trace copper sulphides (chalcopyrite, bornite, covellite) and up to 1 or 2 per cent graphite. These discordant quartz veins trend east-northeast to west-northwest and are likely in a stockwork system. The best sample assayed 14.0 grams per tonne gold and 8.0 grams per tonne silver (Assessment Report 22556). Another sample assayed greater than 1 per cent lead and 1 per cent zinc (Assessment Report 22556).
Drilling in 1989 and 1990 intersected disseminated pyrite and pyrrhotite in fractures, stringers and veinlets in tuff and argillite. Samples taken in 1994 assayed 0.08 to 0.25 gram per tonne gold (George Cross Newsletter No. 61, 1994).
