The Galleon 4-7 occurrence is located in the head waters of Payzant Creek, approximately 2.5 kilometres south east of Port Renfew.

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, gold-bearing quartz-arsenopyrite (-pyrite) veins trend from 60 to 70 degrees are exposed on a logging road. The veins vary in thickness from 2 to 45 centimetres in width and occur in clusters of two to eight veins over a distance of 5 to 15 metres.

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 veins assayed up to 2.88 grams per tonne gold (sample G4-8-1; Assessment Report 25697).

In 2005 through 2010, the area was prospected and sampled as the Yahu Creek, RocDoc and Le Baron 1-2 claims. A sample (I) of quartz vein, taken approximately 350 metres to the south east of the previous samples, assayed 1.57 grams per tonne gold (Assessment Report 29758).
