The TC occurrence comprises a series of mineralized and altered outcrops lying in the vicinity of the confluence of North Trout Creek and Trout Creek, approximately 3.0 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, at the main zone, an area of strong clay alteration and minor silicification, quartz veining and brecciation is developed in quartz feldspar porphyritic monzonite, along the east bank of North Trout Creek, 240 metres northwest of the creek's confluence with Trout Creek. Drilling indicates the zone dips steeply south and is approximately 60 metres wide. Surface exposures contain abundant limonite and pyrolusite. Numerous narrow shears, with rusty clay, are developed throughout the zone. The nature of the alteration suggests this occurrence may be of epithermal origin (Assessment Report 14989). Mineralization consists of disseminated and stringer pyrite, sphalerite, galena and tetrahedrite.
In 1986, drilling yielded intercepts of up to 2.0 grams per tonne silver, 0.54 per cent zinc and 0.09 per cent lead over the final 19.65 metres (22.95 to 42.60 metres down hole), including 1.9 grams per tonne silver, 1.49 per cent zinc and 0.07 per cent lead over 3.0 metres (30.5 to 33.5 metres down hole) of hole S85-1 (Assessment Report 14989).
In 1989, a chip sample from trench TR001E yielded 0.00073 per cent antimony, 0.038 per cent zinc and 0.18 per cent lead over 1.5 metres (Assessment Report 19420, page 33).
Two additional zones (N2 and P4) of mineralization occur along North Trout Creek, approximately 250 metres north of the main occurrence. At the N2 zone, a sheared and clay-altered contact between quartz feldspar porphyry and porphyritic rhyodacite is exposed over a length of 7 metres. Limonite and pyrolusite occur throughout the zone. At the P4 zone a moderately sericite-altered breccia zone lies 40 metres west-northwest. The breccia is comprised of quartz feldspar porphyry and porphyritic rhyodacite fragments and is mineralized with up to 5 per cent disseminated pyrite, with associated limonite and pyrolusite.
In 1989, a chip sample from the N2 zone assayed 10 grams per tonne silver and 0.071 per cent lead over 1.5 metres, whereas a chip sample from the P4 zone yielded 0.101 per cent zinc over 1.5 metres (Assessment Report 19420, page 22 and 24).
Three blocks of altered and skarnified granodiorite, engulfed in quartz feldspar porphyry, occur up to 750 metres south of the main showing on the west side of Trout and North Trout creeks. The granodiorite blocks are variably mineralized with disseminations and blebs of specular hematite, chalcopyrite, pyrite, sphalerite and galena. Chalcopyrite also occurs in quartz veins in one of the blocks.
Another zone of mineralization, referred to as the Diatreme zone, is located near the north bank of Spring Creek, approximately 800 metres east of the main zone. The zone comprises disconnected patches of altered intrusive with zones of breccia or diatreme material associated with secondary manganese oxides. Mineralization comprises pyrite, chalcopyrite and traces of galena and sphalerite associated with magnetite.
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 immediately east of the occurrence as the Boomer property.
