The Murton occurrence is located in the head waters of Murton Creek, approximately 2.5 kilometres east- south east of Port Renfrew.

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.

Locally, pyrite and chalcopyrite occur in felsic and granodiorite dikes, and in quartz veins cutting the dikes and at their contacts. Quartz veins in metagreywacke often carry abundant pyrite, chalcopyrite and occasionally galena.

In 1981 and 1982, JMT Services and Geo-Ex completed programs of geochemical sampling on the area as the Spanish claims. In 1985 through 1987, Pan Island Resources completed programs of geochemical sampling, geological mapping and ground geophysical surveys on the area as the Murton claim. A grab sample (87-M49) of mineralized quartz vein material assayed 0.63 grams per tonne gold (Assessment Report 16507).

In 1997, AGC Americas Gold completed a program of geological mapping and geochemical sampling on the area as the Galleon claims. In 2005, the area was prospected as the Le Baron 1-2 claims. In 2005 through 2010, the area was prospected and sampled as the Yahu Creek, RocDoc and Le Baron 1-2 claims.
