Silver Mines Ltd (ASX:SVL) has enhanced the underground mining potential of the Bowdens Silver Project in central New South Wales with high-grade results from infill and extensional drilling as part of a 30,000-metre program.
Diamond drilling continues to test the potential for high-grade resource extensions for underground mining scenarios at Bowdens focusing on the Northwest High-Grade and Aegean zones.
Reported drill hole locations.
Hole BD21006, drilled to the east of the Northwest High-Grade Zone, returned 2 metres at 443 g/t silver equivalent (146 g/t silver, 3.80% lead, 3.43% zinc and 0.25 g/t gold) from 212 metres and 8.3 metres at 354 g/t silver equivalent (276 g/t silver, 2.15% lead, 0.10% zinc and 0.31 g/t gold) from 263 meres.
Results from BD21011, also in this zone include 13 metres at 264 g/t silver equivalent (188 g/t silver, 1.66% lead, 0.40% zinc) from 207 metres.
Notable results from the Bundarra Zone show a potentially significant 200-metre extension to the southeast and include 6 metres at 311 g/t silver equivalent (35 g/t silver, 3.60% zinc, 2.87% lead and 0.60 g/t gold) from 267 metres.
Three holes were also completed at the Northern Feeder Vein, testing the depth extent where it was modelled to intersect the basement contact and other faults such as the Eastern Fault.
Next on the agenda
Silver Mines has four rigs on-site as part of the expanded program, which is expected to provide the basis for a resource estimation of potential underground mineable resources.
With renewed insight from textural analysis, detailed gravity surveying and VTEM reprocessing, the ongoing drilling at the Northwest High-Grade and Aegean Zones will continue in tandem with targeted diamond drilling of steep feeder veins.
This work includes testing eastern extensions to the Northwest Zone that would link to the Aegean Zone.
In particular, the Northwest High-Grade Zone is still considered to represent a feeder conduit for the Bowdens silver system with a close association between silver and gold in assays and vein textures (colloform banding and pebble breccia).
Drilling is also focusing on the identification of further steep and high-grade vein sets (feeders) in the centre and southern areas of the deposit.
