Diatreme Resources (ASX:DRX) has re-commenced diamond drilling in its quest to uncover large scale porphyry copper mineralisation at the Rosevale Project at Clermont in central Queensland.
As part of Diatreme's joint venture at Clermont, a wholly owned subsidiary of Antofagasta (LON: ANTO) is targeting large +1 million tonne copper deposits, with exploration activities tailored to this end.
A 500 metre deep diamond drill hole has commenced, targeting a high IP anomaly situated between the Gollan and West Copperfield prospects. The hole will be drilled at a dip of 60 degrees eastwards and is expected to intersect the anomaly 150 metres down hole.
At the Gollan Prospect toward the north of the Rosevale Porphyry belt, DRX has defined a wide zone of hematite-bearing propylitic alteration of the intrusives, located in a zone of abundant secondary carbonate copper on surface.
Notably, the geological setting is reminiscent of the high grade Ridgeway deposit at Cadia in New South Wales.
Drilling is expected to take two weeks to complete, with results to be progressively released as they become available.
