Capsule Geology

The WH 1 occurrence is located approximately 1.3 kilometres south-southwest of Whitehead Lake and 4.2 kilometres northwest of Trout Creek.

The area south of Whitehead Lake is underlain by a granite stock of the Eocene Otter Intrusions. The stock trends west-northwest for 3.5 kilometres and is up to 2.5 kilometres wide. It is situated between the Middle Jurassic Osprey Lake Batholith to the south and west, and the Lower Jurassic Pennask Batholith to the east and north.

Locally, a quartz-limonite veinlet, less than 1 centimetre wide, cuts weakly clay-altered, coarse-grained granite. The veinlet strikes 088 degrees and dips 60 degrees north.

In 1988, a sample (L160-R4) yielded 15.9 grams per tonne gold and 1100 grams per tonne silver over 0.10 metre, whereas another sample (L160-R7), taken near the southeast shore of Whitehead Lake and approximately 1.5 kilometres northeast of the previous sample, yielded 0.12 gram per tonne gold and 8.3 grams per tonne silver (Assessment Report 18408).

In 1989, a chip sample, taken across the quartz vein and altered granite, yielded 4.68 grams per tonne gold and 402 grams per tonne silver over 0.5 metre (Assessment Report 19383, page 18).

Another zone of minor mineralization, comprising trace disseminated chalcopyrite in a granite hosting narrow, 2-centimetre wide, quartz veins is located on the former WH 8 claim, approximately 4 kilometres north of the WH 1 occurrence.

Work History

In 1971 and 1972, Royal Canadian Ventures Ltd. and Pan Ocean Oil Ltd. completed programs of prospecting, geological mapping, soil sampling and a 75.2 line-kilometre ground magnetic survey on the area as the TC and PO claims.

The occurrence was discovered by Fairfield Minerals Ltd. in 1988, while prospecting and geochemical (rock and soil) sampling the area as the WH 1-4 claims. The following year, Placer Dome Inc., on the behalf of Fairfield Minerals Ltd., conducted a program of geological mapping, geochemical (rock and soil) sampling, minor trenching and ground magnetic and electromagnetic surveys on the WH 1-8 claims.

In 1990, Fairfield Minerals Ltd. completed a program of geochemical (rock and soil) sampling and minor trenching on the WH 1-8 claims. In 1996, a further program of rock and soil sampling was completed on the WH claims.
