Significant new gold results include:
- KKAC0491: 18 metres of 2.64 g/t gold from 71-89 metres downhole (entirely in native copper zone and ended in mineralisation); and
- KKAC0492: 23 metres of 2.45 g/t gold from 60-83 metres downhole (entirely in gold saprolite zone and ended in mineralisation).
Relative positions of drill holes reported from West Kalkaroo. Saprolite gold zone (yellow) and native copper zone (blue)
Drillhole KKAC0491 was drilled within 3 metres of the previous drill hole KKAC0421, to validate the previously reported elevated rare earth element (REE) and to obtain samples for REE metallurgical recovery test work.
The drill hole was successful on both counts.
Elevated REE levels were confirmed in the twinned hole with total rare earth oxides (TREO) of 6,746 ppm over a 10-metre interval.
Area of drilling at West Kalkaroo in relation to the greater Kalkaroo copper-gold deposit
Havilah technical director Dr Chris Giles said: “West Kalkaroo drilling continues to produce higher than expected gold grades in the saprolite gold and native copper zones.
“We are compiling these results for updated resource estimates and mine planning purposes.
“The confirmation of significant REE mineralisation in association with copper and gold in a new drill hole is very positive and justifies follow-up REE mineral recovery studies using these new drill samples.
“Since commencement of this year’s drilling program Havilah has completed over 30 aircore drill holes at West Kalkaroo.
“Earlier this week we dropped off a further batch of more than 1,800 samples at the Adelaide assay lab and look forward to providing further updates as the results come to hand.”
Drilling adhering to COVID-19 health directives
Over 30 aircore drill holes have been completed this year at West Kalkaroo, the results of which will be incorporated in a revised gold resource estimate for a conceptual pilot open pit.
Drilling will continue at Kalkaroo for the foreseeable future in strict adherence to COVID-19 health directives issued by the South Australian Government.
