Capsule Geology

The Siwash showing is located 23 kilometres west of Vernon, between Bouleau and Naswhito Creeks.

In this area, sedimentary and volcanic rocks of the Devonian to Triassic Harper Ranch Group are intruded by Middle Jurassic granitic rocks. Extensive Eocene Penticton Group volcanic and sedimentary rocks overlie the older units.

A trachytic tuff-breccia paleochannel deposit is in fault contact with trachyandesite flows. A large alteration zone with silica flooding, chalcedonic quartz stockworks and hematitic and goethite staining predominates within the tuffaceous rocks. The alteration zone is 3000 by 750 by 150 metres in area. Minor, very fine-grained pyrite occurs in drusy quartz veinlets. These quartz veinlets, within altered tuffs and flows, carry gold and silver mineralization. Samples assayed up to 5.55 grams per tonne gold and 16.6 grams per tonne silver (Assessment Report 20226).

In 1989, Prosperity Gold Corporation carried out geological mapping, soil geochemistry, magnetic and VLF-EM surveys.
