Capsule Geology

The AR occurrence is located approximately 2.6 kilometres northwest of the north end of Bluey Lake and 2.0 kilometres west-northwest of the south end of Kentucky Lake.

Regionally, the area is underlain by the Upper Triassic Nicola Group, which regionally consists of alkalic and calc-alkalic volcanics and intrusions of island arc origin, and which is the principal component of the Quesnel terrane in southern British Columbia (Geological Survey of Canada Maps 41-1989, 1713A). The area lies in the Central Belt or facies of the Nicola Group (after Preto, Bulletin 69). This belt of rocks mainly consists of subaerial and submarine, red or purple to green augite plagioclase porphyritic andesitic and basaltic flows, volcanic breccia and tuff, and minor argillites and limestone. The volcanics are intruded by bodies of comagmatic Upper Triassic to Lower Jurassic diorite to monzonite. The area is characterized by long-lived, primarily north-striking faults and related fracturing, which originally controlled intrusion emplacement. East-striking faults are subordinate, and commonly offset intrusive contacts.

Locally, two closely spaced trenches expose chalcopyrite and bornite in green volcanic breccia and lahar deposits of the Upper Triassic Nicola Group (Central Belt, Bulletin 69). Alteration minerals include epidote, carbonate, chlorite, quartz and sericite. A third trench located a short distance south of the previous two trenches is reported to expose malachite staining, whereas a fourth trench, located approximately 700 metres south of the first trenches exposed pyrite and chalcopyrite mineralization.

In 2006, a chip sample (K-01) assayed 0.696 per cent copper over 1.5 metres (Assessment Report 28782).

In 2007, a diamond drill hole (K07-05) yielded 0.20 per cent copper over 10.2 metres (11.3 to 21.5 metres down hole; Assessment Report 29728).

Work History

A number of historical trenches, likely dating to the early 1900s, are reported to have been developed on the occurrence area.

In 1978, Belmont Resources Inc. completed a program of soil sampling and a 13.0 line-kilometre ground electromagnetic survey on the area as the AR claim.

In 1982, Nu-Star Resources Corp. completed a ground magnetic and electromagnetic survey on the area immediately west of the occurrence as the Aspen and Kaz claims. In 1983, Belmont Resources Inc. completed a ground magnetic survey on the AR claim.

In 1990, MineQuest Exploration Associates Ltd. completed a minor program of prospecting, geological mapping and rock sampling on the area as the Ley 1-3, Al 1-3 and Ken claims. In 1992, Pacific Copper Fields Inc. and MineQuest Exploration Associates Ltd. completed a program of geological mapping and rock sampling on the claims.

In 2006, Bold Ventures Inc. completed a program of geochemical (rock and soil) sampling and a 28.0 line-kilometre induced polarization survey on the area as the Casper claims of the Kentucky Lake property. The following year, six diamond drill holes, totalling 1025.9 metres, were completed on the property.

In 2012, Enduro Metals Corp. completed a photogeological structural (lineament) interpretation on the area as the Tom Cat property.
