The Redbird occurrence is located near the east side of a small un-named lake, northwest of Stump Lake and approximately 750 metres east-southeast of the south end of Kullagh Lake.
The occurrence area 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, the country rocks are cut by the north-northeast–trending Stump Lake fault. Within the occurrence area, the dominant structural trend is northeast, whereas numerous subordinate fractures trending northwest. Alteration and mineralization are structurally controlled. Zones of bleaching, oxidation and silicification reflect the regional trend, whereas 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. Quartz veins located within this zone contain 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) yielded 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).
Work History
In 1980, Demus Petroleum completed a program of soil sampling on the area as the Fir claims. In 1983, Chevron Canada Resources Ltd. completed four diamond drill holes on the area as the CIN and DY claims. In 1985, BP Resources completed a program of soil sampling and ground geophysical (magnetic and electromagnetic) surveys on the area as the CIN, DY and Microgold claims. In 1987, Asamera Minerals Inc. completed three diamond drill holes, totalling 917.7 metres, on the CIN and Microgold claims.
During 1991 through 1996, Canquest Resource Corporation conducted programs of geological mapping, soil sampling, a 4.6 line-kilometre induced polarization survey and five diamond drill holes on the Redbird, CIN and DY claims.
In 2006 and 2007, Totem Minerals Inc. completed programs of prospecting, geological mapping and geochemical (rock and soil) sampling on the area as the Microgold property.
