Queensland-based copper explorer Coppermoly Limited (ASX:COY) (“the Company”) is pleased to announce successful completion of a 654-metre reverse circulation (RC) drilling programme at the Whitehorse copper-gold porphyry prospect on its farm-in venture with ActivEX Limited (ASX:AIV) at Esk Trough, Queensland.
The nine-hole drilling programme at Whitehorse (refer to Table 1) tested for extensions to significant historical copper and gold grades near surface including:
- 38m at 0.74% Cu and 0.13 g/t Au from 20m depth, including 10m at 1.87% Cu and 0.14 g/t Au from 22m depth
- 44m at 0.43% Cu and 0.11 g/t Au from 22m, including 8m at 1.2% Cu and 0.08 g/t Au from 36m depth
- 2m at 2.42% Cu from 30m depth.
Results from at least eight of the nine current RC drillholes at Whitehorse indicate secondary copper enrichment forming as a chalcocite blanket above the primary grade copper at depth. The in-field Niton portable XRF (x-ray fluorescence) measurements from drill samples indicate that the copper enrichment occurs between 19m and 36m depth in zones 4m to 21m thick.
