Capsule Geology

Several small quartz veinlets occur within sheared black slates adjacent to the highway on the north side of the Pend d'Oreille River. The claim is close to the Pend d'Oreille thrust and the Waneta thrust fault with associated faulting within units of the Lower Jurassic Elise Formation (Rossland Group) volcanics and adjacent to small syenitic intrusions of the Middle Eocene Coryell Intrusions.

The veinlets are described as being parallel to a northeast trending gossanous shear zone, vary in width from 5 to 80 centi- metres and are traceable for about 80 metres along strike. The quartz gangue hosts galena, sphalerite, chalcopyrite and pyrite. Mineralization is erratic and tonnage potential is considered very limited. A sample collected from a gossanous zone assayed 548.58 grams per tonne silver, 6.34 grams per tonne gold, 0.08 per cent lead, and 0.28 per cent zinc in selected samples (Assessment Report 10524).
