BORNITE, BAR, DANA, TEX prospects.
The area is underlain by Jurassic Hazelton Group volcanics comprised of andesitic to rhyolitic flows, tuffs, and breccia which strike uniformly northwest and dip about 80 degrees northeast. Mineralization consisting of chalcopyrite, bornite, and tetrahedrite occurs mainly as fragmental rims and disseminations in the matrix of a very strongly silicified andesitic to rhyolitic pyroclastic rock. Minor galena and sphalerite have also been reported. Scattered specks of chalcopyrite also occur in a strongly silicified, buff coloured rhyolite approximately 150 metres to the north. Silver values up to at least 65.14 grams per tonne have been obtained. Barite occurs in small veins (Assessment Report 15479).
In 1986, a surface projection of a low-grade copper-silver bear- ing zone was defined by diamond drilling. The zone is approximately 300 metres long and up to 7 metres wide, striking northwest-southeast.
The drilling intersected a strongly silicified, stratabound zone with sporadic stockwork development over 20 metres in true thickness, and with a steep northeast dip. Within the zone, weak copper-silver mineralization occurs as disseminations and irregular microvein fillings of chalcopyrite and tetrahedrite. Gangue minerals include quartz, calcite, barite, pyrite and jasperoid. The zone appears to be faulted 50 metres below the surface and may be a favourable host for an epithermal precious/base metal deposit. (extract from MINFILE No 093L 012).
