Capsule Geology

The Dambo occurrence is located to the southwest of Picket Lake, approximately 4 kilometres north of the Nechako Reservoir’s northern shore.

The Dambo area is underlain by felsic (rhyolitic) rock of the Eocene Ootsa Lake Group and minor intermediate volcanics of the Cretaceous Kasalka Group. These have been intruded by feldspar porphyry dikes.

Locally, rhyolite breccia, is interbedded with minor rhyolite flows and cut by quartz feldspar porphyry dikes. The rhyolite shows widespread weak to moderate clay alteration, and contains ubiquitous minor disseminated iron sulphides, largely weathered to limonite. Traces of galena and titanium oxide have also been noted.

WORK HISTORY

In 1980, BP Minerals Ltd. completed an exploration program of line cutting, geological mapping, a soil geochemical survey and electromagnetic surveys. In 1981, a sample from a sulphide rich shear zone and from pyritic clasts in a rhyolites breccia returned up to 100 parts per billion gold and 1.7 parts per million silver (Assessment Report 9788). In 1988, Exeter Mining Inc. acquired the property and completed minor trenching and several grid surveys including soil geochemical and magnetics. A ground horizontal loop electromagnetic survey, rock and soil geochemical sampling and further geological mapping was completed over the following two years. In 1990, sampling of a quartz-veined, siliceous rhyolite breccia returned up to 19.9 grams per tonne silver; other samples from pyritic rhyolites returned up to 33 parts per billion gold (Assessment Report 20630).

In 2011 and 2012, Quartz Mountain Resources Ltd held the considerable Buck and Karma property which contained a number mineral showings including the: Bob Creek (093L 009), Irk (93L 265), Lewes River (093L 261), John (093L 059) and Shelford Hills (093E 085). In 2011, the company conducted 3906 kilometres of aeromagnetic surveying (Assessment Report 33176). As a result, the company concentrated on 7 areas of interest designated from A to G. Area A contained the Bob Creek showing and Area D the Lewes River showing. In 2012, the company conducted 29.5 line-kilometres of induced polarization in work areas C and D. The company also collected a total of 1489 soil samples, 159 rock samples and 10 silt samples on the Buck and Karma properties. Of 7 areas tested with soil geochemistry, only areas A, C, E and G had elevated results (Assessment Report 34048). The Karma was contained in NTS map sheets 93L/01, 02 and 07 and 93E/15 and 16 and the 2012 airborne survey also covered the Dambo showing.

See Shelford Hills (093E 085) and for Bob Creek (093L 009) for further details.
