The BW2 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 the southwest part of the BW2 claim, at an elevation of 1480 metres, two samples were taken along the margins of a minor shear zone, striking 170 degrees and dipping 85 degrees to the east. Sample 32614 was taken from a stockwork of quartz veinlets over a width of twenty centimetres. The sample, containing chalcopyrite and pyrite, yielded a value of 1.13 percent copper (Assessment Report 20775). Other metal values were low. Sample 32615 was taken from a fifteen centimetre wide quartz vein a few metres to the east which contained pyrite and chalcopyrite. It yielded values of 1.69 percent copper and 0.066 per cent zinc (Assessment Report 20775).
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. 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 was carried out and total of 19 rock samples were collected (Assessment Report 20775).
