The Redbird showing is underlain by andesitic flow breccia and minor intercalated conglomerate of the Upper Triassic Nicola Group which have been pervasively altered to lower greenschist facies. Approximately one kilometre east of the property, country rocks are cut by the north-northeast trending Stump Lake fault. Within the occurrence area, the dominant structural trend is northeast with numerous subordinate fractures trending northwest. Alteration and mineralization is structurally controlled. Zones of bleaching, oxidation and silicification reflect the regional trend, while more local alteration and quartz veining follow the subordinate direction.
One main zone of alteration comprises intense fracturing and pervasive silica and clay alteration. This zone is exposed over an area measuring 360 by 220 metres. The alteration mineralogy consists of chlorite, gypsum, epidote, fluorite, hematite, kaolinite, quartz and pyrite. Within this zone are quartz veins containing variable amounts of chalcedony, gypsum, fluorite and finely disseminated pyrite. The veins and some of their alteration envelopes host gold values up to 3.0 grams per tonne (Blanchflower, 1986).
Zoned quartz-fluorite veins (pyrite is present with an illitic mixed-layer clay) assayed 0.7 grams per tonne gold, 3.0 grams per tonne silver, 0.0074 per cent copper and 0.064 per cent molybdenite (District Geologist, 1985).
Canquest Resource Corporation conducted geological, geochemical, and geophysical surveys and drilling from 1991 to 1997.
