The Boomer (Zone 2) occurrence outcrops along a southeast-flowing tributary of Trout Creek, approximately 600 metres northwest of the tributary's confluence with Trout Creek and 3.2 kilometres east 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, on the Boomer 1 claim, minor amounts of pyrite, sphalerite and galena occur in quartz veins and along fractures in very altered granodiorite, surrounded by quartz feldspar porphyritic monzonite of the Otter Intrusions. Trenching on both banks of the creek intersected quartz feldspar porphyritic monzonite exhibiting moderate to strong silica and sericite alteration, moderate clay alteration and minor to moderate chloritization. The monzonite is occasionally cut by narrow shear zones and is mineralized with up to 8 per cent pyrite, as disseminations and fracture fillings.
In 1989, a sample taken across a clay-altered shear zone exposed in trench 785E, located west of the creek, yielded 8.2 grams per tonne silver over 1.5 metres, whereas a sample of quartz feldspar porphyry from trench 825E, located east of the creek, yieldd 0.125 per cent zinc over 12 metres (Assessment Report 19420).
Another zone of pyrite-galena mineralization in a biotite-hornblende quartz diorite is reported to be exposed along a stream bank on the Boomer 4 claim, approximately 2.8 kilometres east-southeast of the previous occurrence.
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.
In 2002, In-Sync Industries Inc. completed a 5.5 line-kilometre induced polarization survey on the area as the Spring property. The following year, a program of trenching and rock sampling was completed.
In 2006, David Javorsky completed a program of prospecting, sediment sampling and an induced polarization survey on the area as the Trout Creek property.
In 2013, DWG Consultants Ltd. completed a 4.0 line-kilometre ground magnetic survey on the area as the Boomer property.
