The Bar occurrence is located at an elevation of approximately 1560 metres on a north-northwest–facing slope, south of Inkikuh Creek and approximately 2.8 kilometres west of the west end of Calling Lake.
The area is underlain by quartz diorites to granodiorites of the Upper Triassic to Lower Jurassic Guichon Creek Batholith. Border phase rocks to the west are in contact with Guichon variety (Highland Valley phase) rocks to the east. The contact strikes 330 degrees (Assessment Report 4782). Fault gouge strikes northwest through Guichon granodiorite close to the contact. Mineralized fractures appear most frequently in three directions: 075, 100 and 150 degrees with near vertical to vertical dips.
Alteration is confined close to fractures and comprises chlorite, biotite, epidote, potassium feldspar and minor quartz. Minor chalcopyrite and/or bornite with malachite occurs locally as disseminations or fracture fillings and coatings within alteration envelopes. Trench 30-W exposes chlorite-altered hornblende granodiorite fractured at 095 degrees across 2 metres. Chalcopyrite occurs as sparse fracture fillings. Other trenches, located northwest and west of previous trench, exposed bornite as fracture fillings with malachite. A trench to the northwest (Bar 39 claim) exposes a 6-metre wide shear zone carrying chlorite, hematite, minor chalcopyrite and malachite. Pyrite is conspicuous in its absence.
In 1972, a visual estimate of the copper grade in trench 30-W is reported at 0.25 per cent (Assessment Report 4069).
Work History
In 1965, Cominco Ltd. completed a 12.8 line-kilometre ground magnetic survey, geological mapping and trenching on the Nancy, B.L. and Tom claims.
In 1967, Northlode Exploration Ltd. completed a 40.8 line-kilometre ground magnetic and induced polarization survey on the Bar and MB claims. In 1972, a program of geological mapping, rock sampling and trenching was completed on the Bar claims. At least three drillholes are indicated to have been drilled by this time; however, the date(s) and results of the drilling are unknown. The following year, a program of geological mapping was completed.
In 1976 and 1977, Leonard Peckham prospected the area as the Kik claims.
In 1980, Cominco Ltd. completed 60.0 line-kilometres of ground magnetometer and induced polarization surveys on the area as the Island property. The following year, 22.9 line-kilometres of induced polarization surveys were completed on the property. In 1982, Cominco Ltd. completed an induced polarization survey on the area as the Island property.
