The Spring (Zone C) occurrence is located on the east bank of North Trout Creek, approximately 1.4 kilometres northwest of the creeks’ confluence with Trout Creek and 2.3 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, a dike of altered andesite is in contact with an altered tectonic breccia containing fragments of quartz feldspar porphyritic monzonite and quartz diorite. The occurrence is exposed in outcrop over a length of 50 metres. The dike is partially silicified, chloritized and carbonatized and contains minor disseminated pyrite and galena. The tectonic breccia is sericite altered and mineralized with minor disseminated pyrite and chalcopyrite. The contact between the two units is sheared and intensely clay altered. It strikes 180 degrees and dips 30 to 45 degrees east. The shearing, silica flooding and vuggy texture of the showing suggests a possible epithermal origin for this mineralization (Assessment Report 19420). Anomalous metal values occur in or near the contact.
In 1989, a chip sample assayed 0.088 gram per tonne gold, 7.6 grams per tonne silver, 0.287 per cent lead and 0.161 per cent zinc over 7.7 metres, whereas other chip samples yielded up to 0.103 gram per tonne gold over 4.5 metres and 0.075 gram per tonne gold, 27.0 grams per tonne silver, 0.550 per cent lead and 0.330 per cent zinc over 1.5 metres (Assessment Report 19420, page 21).
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.
