The Bank Group showing is located on the north bank of China Creek, 21 kilometres east of Port Alberni. It is located on or near the southwestern corner of the Singapore claim just southeast of the Debbie/Yellow property (092F 079, 331).
The area is underlain by volcanic and volcaniclastic rocks of the Devonian Duck Lake Formation (Sicker Group) which has been intruded by Early to Middle Jurassic Island Plutonic Suite dioritic rock. The showing is hosted in andesitic rocks that have been altered, fractured and sheared.
A series of open cuts have been dug on quartz veins carrying pyrite, chalcopyrite and galena. The mineralized zone, striking 200 degrees and dipping 20 to 40 degrees west, was reported to be 3 metres wide extending 100 metres or so along strike. A grab sample from the dump assayed trace gold, 34 grams per tonne silver and 3.2 per cent copper (Annual Report 1917 p. 247).
Quartz-carbonate veining, generally 1 to 5 millimetres in width, is common in the area and pyrite content increases in veined rocks.
From 1963 to 1966, Gunnex Limited completed programs of geological mapping, geochemical sampling and prospecting on the area as the Alberni claim. Apparently no mineralization was encountered. In 1984, MPH Consulting completed a program of geological mapping, prospecting and geochemical sampling. Exploration resulted in one anomalous sample (0.9 gram per tonne) from a quartz-carbonate veined, sulphide rich volcanic rock taken from near the south boundary of the claim. In 1987, the Singapore claims were staked by S.E. Angus on the previously existing Alberni claim and were explored through 1991 by Blue Sun Resources Corporation. . Results from a 1987 geochemical survey were not significant. The 1988 program results confirmed the previous anomalous results and demonstrated the erratic nature of the high values.
