The Boomer 3 (Zone M) occurrence is located at an elevation of approximately 1320 metres on an east-facing slope, west of Trout Creek and approximately 3 kilometres southeast of Whitehead Lake.

The area south and east of Whitehead Lake is underlain by a granitic 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, west and north, and the Lower Jurassic Pennask Batholith to the east.

Locally, trenching has exposed a porphyritic quartz-felspar monzonite and quartz diorite hosting pyrite and sphalerite mineralization associated with a clay-altered shear zone.

In 1989, a 6.0-metre chip sample from a clay-altered shear zone in a quartz diorite yielded 3.8 grams per tonne silver and 0.042 per cent zinc, including a 1.5-metre section yielding 0.300 gram per tonne gold and 2.2 grams per tonne silver (Assessment Report 19420).

Work History

This area was first explored by Pan Ocean Oil Ltd. in 1971 and 1972 with the completion of soil, silt, geological and magnetometer surveys.

Additional silt and soil sampling was conducted on the area as the Spring 1-4 claim by Brenda Mines Ltd. in 1981. Also at this time, Canadian Nickel Co. Ltd. completed a program of prospecting, geological mapping and geochemical (rock, silt and soil) sampling on the area immediately south of the occurrence as the Trout 1-2 claims.

In 1985, Boomer Resources Inc. staked the area as the Spring property and completed a program of trenching. The following year, three diamond drill holes, totalling 137 metres, were completed on the property. In 1987, Golden Pick Resources Ltd. completed a 3.5 line-kilometre induced polarization survey on the Spring and Boomer claims.

In 1988 and 1989, Placer Dome Inc. carried out extensive programs of geological mapping, geochemical (rock and soil) sampling, trenching, test pitting and ground magnetic, electromagnetic and induced polarization surveys on the area as the Spring, Boomer, Pick and Ak claims.
