The Rich Rock West showing is located in the upper watershed of Rendell Creek, approximately 2 kilometres northwest of Lightning Peak.

The showing occurs in a pendant of greenstone and schist of the Devonian-Triassic Harper Ranch Group which is hosted by diorite and granodiorite of an unnamed Middle Jurassic intrusion.

Mineralization in the showing consists of a pyritic gouge with quartz and carbonate lenses in a shear zone within pyritic and siliceous meta-volcanics. The zone and host rocks are rusty weathering. Schist is also exposed in a trench at the showing.

From 1968 to 69, International Mines Services Ltd. carried out a soil geochemical survey in the general area to the north and east of the showing

From 1984 to 85, Zalmac Mines Limited carried out VLF-EM and IP surveys over portions of the BIG P 1, 2 & 3 claims in the general area to the northeast of the showing. The 1984 surveys identified 3 polarizable anomalies coincident with east-west VLF-EM conductors. It was speculated that these anomalies may represent mineralized shear zones. In 1985, several east to northeasterly trending VLF-EM conductors were identified in the area. Trench number TR85-8 was dug in this area, exposing a pyritic shear zone in meta-volcanics and schist. A grab sample from the trench assayed 7.2 grams per tonne silver and 0.28 per cent lead (Assessment Report 13861).

In 1991, the showing was examined by Placer Dome Inc. Three grab samples assayed 11.8, 17.6 and 18.2 grams per tonne silver (Assessment Report 22875).

In 2011, Tower Resources optioned the property and completed a program of geological mapping and sampling from outcrops, trenches, and dump piles located near old workings. New areas of precious metal enriched rocks were also identified during this work. The 39 samples, collected over an area of 4 by 1.3 kilometres, average 112 grams per tonne silver and 0.9 gram per tonne gold (http://www.towerresourcesltd.com).
