The BB showing is located on a creek flowing into Botanical Beach, approximately 800 metres north of the beach.

The area, according to Muller, is underlain by a metagreywacke schist unit and an argillite metagreywacke unit, both of the Jurassic to Cretaceous Leech River Complex (Geological Survey of Canada Open File 821). The former unit consists of metagreywacke, meta-arkose and quartz-feldspar biotite schist; the latter consists of thinly bedded greywacke and argillite, slate, phyllite and quartz-biotite schist. Felsic and granodiorite dikes have intruded both units.

Locally, a quartz vein hosting native gold is exposed over 6 metres and varies from 10 to 30 centimetres in width. Pyrite is present but generally in minor quantities, although many of the veins have abundant iron oxide stains with minor gossan development; other sulfides include arsenopyrite, and possibly pyrrhotite or electrum. Gangue mineralization includes thin bands of carbonaceous or graphitic material, iron and arsenic staining, chlorite, epidote, and biotite. Gold-bearing quartz stockwork veining is present where the veining trends 60 degrees and 120 degrees.

In 1997, AGC Americas Gold completed a program of geological mapping and geochemical sampling on the area as the Galleon claims. Chip sampling of the vein yielded values from 0.58 to 104.52 grams per tonne gold (Assessment Report 25697).

In 2005 through 2010, the area was prospected and sampled as the Yahu Creek, RocDoc and Le Baron 1-2 claims.
