Capsule Geology

The Coyote showing lies in the Coyote Creek drainage basin, approximately 1.2 kilometres west of Ealue Lake and 10.5 kilometres south-southeast of the village of Iskut.

The property is extensively covered by Quaternary surficial deposits; limited bedrock exposures suggest that the underlying geology consists of flows, tuffs and breccia of the Lower Jurassic Hazelton Group. At the Coyote showing, this sequence has been intruded by a monzodiorite body which was itself intruded by a quartz monzonite dike, possibly related to the Early Jurassic Rose and Edon plutons (Geological Survey of Canada Open File 1080).

The Coyote showing comprises a mineralized quartz vein with minor sections of stockwork hosted by a quartz monzonite dike. The hostrock has undergone propylitic alteration with quartz-sericite alteration concentrated along the vein margins. Mineralization comprises locally abundant disseminated pyrite and pyrrhotite with rare disseminations of molybdenite and chalcopyrite. Analytical results from drill chips were not reported.

The area was initially explored in 1975 by geological and geochemical means, followed by a limited (five holes, 293 metres) percussion drilling program. The property has seen minimal exploration since that time. During the course of acquiring an option on the Rok property in 2004, Firesteel Resources Inc. undertook a small rock and soil geochemical sampling program in the area of the Coyote showing. Forty-eight soils and 33 rock samples were taken from a small grid. In 2005, a helicopter-borne geophysical survey by Aeroquest Ltd. was carried out on behalf of Firesteel Resources Inc. on the Rok property. The survey comprised a new tri-directional magnetic gradiometer system, and a gamma ray spectrometer system. The airborne survey was flown at 200 metre line spacings with a total survey coverage of 611.4 line kilometres. In 2009, Brett Resources Inc. initiated exploration for copper-gold-molybdenum mineralization over a coincident, airborne magnetic high anomaly outlined west of the Coyote showing by the Aeroquest Ltd. survey carried out in 2005. Grid lines cut in the fall of 2007 at approximately 200 metre spacings were resurrected and re-flagged with picket stations established at 50 metre intervals. The lines were covered by ground magnetic and induced polarization geophysical surveys and soil sampled on 50 metre spacings. A total of 23.5 line kilometres (on eight grid lines) of induced polarization and ground magnetic surveys were completed over the Coyote grid. Additional soil sampling at 50 metre intervals was carried out along the access road to the Red Chris exploration camp and along Ealue Lake road. A total of 378 soil samples were collected from eight cut grid lines plus 1900 metres along the Red Chris exploration camp access road and 1600 metres along the Ealue Lake road.
