The Blue Bell showing is located on the southeast side of Anderson Lake near the mouth of Wade Creek, 3 kilometres northeast of D'Arcy, British Columbia.
In the region, the Cadwallader and Ferguson faults transect sedimentary and volcanic rocks of the Mississippian to Jurassic Bridge River Complex and the Upper Triassic Cadwallader Group. The above sequence lies between bodies of the Jurassic to Cretaceous Coast Plutonic Complex and outlying Cretaceous and/or Tertiary intrusions. The area is underlain by granodiorite and quartz diorite of the Cretaceous to Tertiary Bendor pluton. The Bridge River Complex consists of greenstone, chert, basalt, argillaceous siltstone, phyllite, biotite schist and felsite. These have been intruded by medium- grained quartz diorite and porphyritic border phases of the Bendor pluton.
Locally, a shear zone, at least 300 metres wide, has brecciated borders and may be an altered porphyry dike. A zone of mineralization, trending north-northwest and dipping 69 degrees east, is 30 metres wide and 150 metres long. The zone contains quartz and calcite infilled fractures with pyrite, galena, sphalerite and an unidentified manganese mineral disseminated throughout. Argentite is associated with galena in calcite.
In 1995, a two samples (66559 and 66560) of quartz vein containing pyrite, galena and sphalerite and cutting quartz diorite, yielded 14.4 and 23.2 grams per tonne silver, 0.32 and 0.52 per cent lead and 0.12 and 0.05 per cent zinc across 0.2 and 0.1 metre, respectively (Assessment Report 24126).
In 1925, two adits were reportedly driven on polymetallic mineralization. In 1965, Bralorne Mines examined the property and recommended further work based on geological mapping and sampling results. In 1985, the area was prospected and sampled as the Mac Attack claims. In 1995, Verdstone Gold Corporation completed a program of rock and soil sampling, geological mapping and a 1.2 line-kilometre ground magnetic survey on the area as the Penny claim.
