The Vancouver showing is located on the Vancouver No.3 Crown Grant (L.4125) by the Granduc Road, north of the Woodbine workings (104B 090) and 24 kilometres north of Stewart, British Columbia. The majority of the work on the property was carried out in 1929 during the search for the extension to the Silbak Premier "West" or "Northwest" mineralized zone. For a more extensive geological de- scription and bibliography refer to the Silbak Premier Mine (104B 054).
The showing is located in the Intermontane Belt, bounded on the west by the Coast Crystalline Complex and on the east by the Bowser Basin, in the volcanic arc assemblage of the Stikinia Terrane.
Mineralization is hosted in Late Triassic to Early Jurassic Hazelton Group, Unuk River Formation. The Hazelton Group is a northwest trending belt of folded metavolcanic rocks containing a thick sequence of argillites and siltstones infolded along a synclinal axis.
The showing is hosted in the Unuk River Formation andesite flows, breccia and lapilli tuff. This sequence is intruded by the Early Jurassic Texas Creek plutonic suite porphyry dykes and is unconformably overlain by volcaniclastic and epiclastic rocks. This package is intruded by extensive Eocene Hyder granitic dykes and they, along with several faults, have "chopped up" the area.
Silicified potassium feldspar porphyry dykes strike north across the property. Mineralization is contained partially in the dykes and partially in the andesite tuff commonly as grey siliceous breccia or sometimes in quartz stringers up to 6 centimetres wide. Silicifica- tion is most intense in mineralized zones. The host rocks are sheared and fractured to some extent and contain minor disseminated pyrite.
Mineralization on the property consists of blebs and dissemin- ations of pyrite and rare small blebs and stringers of galena and sphalerite.
An adit driven on a porphyry dyke exposed a 2.7 metre wide silicifed zone mineralized with pyrite, sphalerite and galena. The zone strikes 172 degrees and dips 30 degrees west. A 2.74 chip sample across the best mineralization in this zone was 2.057 grams per tonne gold, 20.57 grams per tonne silver and 0.4 per cent zinc (Minister of Mines Annual Report 1936, page B12).
