Vancouver — A newly completed 12-hole reverse-circulation drill program by Silver Standard Resources (SSO-V) has expanded the outline of silver mineralization at its wholly owned Bowdens property in New South Wales, Australia.
Located 200 km northwest of Sydney, the 1,500-metre program tested for mineralized extensions of the Bowdens deposit to the northeast and southeast and completed infill drilling in the northwest.
At the Bundarra North zone of the deposit, three of six holes cut significant zones of silver mineralization. Highlights include:
- Hole 155 — 24 metres grading 114 grams silver per tonne;
- Hole 156 — 15 metres grading 161 grams silver; and
- Hole 163 — 19 metres grading 95 grams silver.
Two holes, collared on the Main South zone, returned 79 metres grading 86 grams silver and 40 metres averaging 149 grams silver, respectively.
On the Main zone, four holes returned promising values, ranging up to an impressive 284 grams silver over 46 metres in hole 162.
Mineralization over the 370-sq.-km project is largely hosted by Permian volcanic flows and breccias, which are underlain by older volcanogenic sediments and capped by younger sediments. The company ranks the deposit as a low-sulphidation epithermal system that produced mineralization in the form of silver sulphides, galena and a low-iron sphalerite.
At last count, the deposit holds an indicated and inferred resource of 18.8 million tonnes grading 99 grams silver, 0.32% lead and 0.37% zinc.
