The reverse circulation (RC) and diamond drilling targeted the East Thomson’s Dome and Telfer West prospects, with initial results indicating the presence of high-grade mineralisation as well as gold anomalism.
Telfer West covers an area of around 121 square kilometres and is 25 kilometres northwest of the Telfer mine, while East Thomson’s Dome is just 5 kilometres from Telfer.
Collated geological and geophysical data suggests that a surface geochemical anomaly and an induced polarisation (IP) anomaly at Telfer West may represent a steep, north-plunging, high-grade shoot.
The IP anomaly lies beneath a drill hole that intersected 39 metres at 1 g/t gold from 333 metres and 36 metres at 0.6 g/t from 396 metres.
Diamond drilling was undertaken to target the high-grade shoot, intersecting a zone of silicified and fractured quartzite with multiple quartz stockwork-style veins containing pyrite and arsenopyrite.
This intersection is consistent with the style of stockwork mineralisation seen in previous drilling at Telfer West.
Drill core from both holes are being cut and sampled for chemical analysis.
Following-up a 39 g/t gold intersection
Drilling at the N31 Reef at East Thomson’s Dome in July intersected high-grade, near-surface gold, in a geological setting similar to that of the high-grade reefs at Telfer.
This intersection assayed 3 metres at 39 g/t gold from 9 metres.
Encounter completed a 9-hole RC and diamond drill program at N31 and has received most assay results.
Several drill holes contained gold anomalism in the range of 0.1-0.5 g/t gold towards the bottom of the holes, but drilling did not establish an extension of the high-grade gold intersected previously.
An assay adjacent to the high-grade intersection remains pending, as well as a 40-metre extension to a hole nearby.
