Capsule Geology

The Truax II is underlain by granodiorite of the Cretaceous to Tertiary Bendor pluton. The contact between the intrusive and steeply dipping sediments and volcanics of the Mississippian to Jurassic Bridge River Group trends northwest-southeast across the northeast corner of the property.

Mineralization occurs in veins related to shear structures in the granodiorite. The veins range from 15 centimetres to 2.5 metres in width, strike northwest-southeast and are relatively flat lying. Pods and disseminations of massive stibnite and sphalerite along with realgar, orpiment, arsenopyrite, pyrite, tetrahedrite and traces of ruby silver occur in quartz-carbonate gangue. Samples assayed 0.34 grams per tonne gold, 456 grams per tonne silver and 16.63 per cent antimony (Property File - Tomlinson, 1971).

The surrounding granodiorite is intensely altered and gossanous just south of the Truax Gold II claim. Mineralization consisting of finely disseminated molybdenite and pyrite is reported in argillic- sericitic altered granodiorite. Work on the property has been mainly trenching.
