Capsule Geology

The Silverside Extension occurrence is located on high ground west of Tommy Creek.

The area is underlain by Mississippian to Jurassic Bridge River Group cherty sediments and basaltic greenstones that strike northeast, dip steeply northwest and are intruded by a stock of Cretaceous to Tertiary Bendor pluton granodiorite. Tertiary (?) porphyry dikes and a mafic dike also cut the metasediments.

Locally, a gossanous shear zone, exposed by trenching in an area of anomalous gold-in-soils, hosts pyrite, stibnite and chalcopyrite mineralized quartz veins. In 1986, a chip sample of trench S2 yielded 0.7 gram per tonne gold over 11.0 metres, while grab samples yielded up to 1.8 grams per tonne gold (Assessment Report 15304).

In 1986, Fairchild Resources completed a program of rock and soil sampling, trenching, geological mapping and ground geophysical surveys on the area as the Silverside Extension. In 1987 and 1988, Levon Resources completed programs of soil sampling and an airborne geophysical survey the area. In 1995, a program of rock and soil sampling was completed.
