The BW area is underlain by a stock of the Early Jurassic Texas Creek Plutonic suite consisting of monzodiorite to gabbro which is in contact with marine sedimentary and volcanic rock of the Upper Triassic Stuhini Group.
In 1989, sample 447011 was taken from a fifteen centimetre wide sulphide-bearing quartz vein hosted by granodiorite. It assayed 1.30 grams per tonne gold metals (Assessment Report 20775). This was a select sample of the sulphide rich portions of the vein. Grab sample 32605 was taken from the same vein during the 1990 field program, yielding values of 0.72 gram per tonne gold, 0.094 per cent copper, and low values for other precious and base metals (Assessment Report 20775).
Sample 32606 was taken approximately 450 metres to the southeast of sample 32605. It was taken from a five centimetre wide quartz vein, containing one to two percent pyrite, which yielded 830 parts per billion gold when analyzed. Other base and precious metal values for this sample are low.
Work History
In 1989, Consolidated Goldwest Resources Ltd carried out reconnaissance exploration on the B.W. claims, taking 22 field-sieved stream sediment samples, one silt sample and seven rock samples (Assessment Report 19517). High gold values were obtained from three stream sediment samples from Snowy, Mouse and Notch Creeks which drain from a gossanous area.
In 1990, Consolidated Goldwest Resources Ltd carried out three days of exploration on the Anuk River South (BW) claim group, consisting of geological mapping and prospecting. Prospecting and reconnaissance geology were carried out using a 1:10,000 topographic orthophoto as a base. A total of 19 rock samples were collected (Assessment Report 20775).
