The Bank 2 (B95-4) occurrence is located at an elevation of approximately 1440 metres on a southeast-facing slope, north of Simem Creek and approximately 3.4 kilometres south-southwest of Sunday Lake.
Regionally, the area is underlain by granite to granodiorite of the Upper Jurassic Osprey Lake Batholith, which has been intruded by granodioritic rocks of the Eocene Otter Intrusions to the northwest.
Locally, a trench (B95-4) exposes a 10-centimetre wide quartz-carbonate vein or zone of alteration with pyrite in a clay-altered, jointed and sheared granite. The vein strikes 101 degrees and dips 84 degrees northeast. Narrow andesite and quartz porphyry dikes, up to 2.5 metres wide, are also reported in the area of the mineralized vein. The granite adjacent to the dikes is strongly sheared and clay-saussurite-limonite altered. Other veins hosting similar mineralization plus minor galena and sphalerite are exposed by trenches approximately 400 metres north of trench B95-4.
In 1995, a sample (B954-8D) of the quartz vein and wallrock in exposed in trench B95-4 yielded up to 2.38 grams per tonne gold, 162.1 grams per tonne silver and 0.35 per cent copper over 0.15 metre, whereas a sample (B954-12) taken near a dike contact yielded 3.24 grams per tonne gold and 7.5 grams per tonne silver over 0.35 metre (Assessment Report 24394).
Also at this time, sampling of the trenches to the north yielded values up to 0.09 gram per tonne gold, 16.1 grams per tonne silver, 0.28 per cent lead and 0.52 per cent zinc in trench B95-1; 0.33 gram per tonne gold and 8.1 grams per tonne silver over 0.8 metre in trench B95-2 and 0.59 grams per tonne gold with 35.3 grams per tonne silver over 0.3 metre in trench B95-3 (Assessment Report 24394).
Work History
During 1988 through 1995, Fairfield Minerals Ltd. completed programs of geochemical (rock and soil) sampling, 56 overburden drillholes, totalling 766.5 metres, trenching and 35.5 line-kilometres of ground magnetic and electromagnetic surveys on the area as the Bank property.
