THE DRILL SERGEANT: Geopacific Resources (ASX: GPR) has encountered high gold grades to follow up recent high-grade copper results achieved at the company’s multi-vein sulphide Kou Sa project in Northern Cambodia.
GPR has reported the first gold assays from the first diamond hole (KDH002) drilled into Prospect 150, which included:
3.9 metres at 16.47 grams per tonne gold and 3.13 per cent copper from 33.4 metres, including 0.6 metres at 93.2 grams per tonne gold from 34.6 metres.

Geopacific said it was still waiting results from a further five follow-up RC holes drilled at Prospect 150 (previously called the Porphyry prospect), which have intersected this zone said to be characterised by high chalcopyrite over approx. 300 metres strike.
“This is a stunning start to our program with the intersection of strong gold grades in a zone of coincident copper,” Geopacific Resources managing director Ron Heeks said in the company’s announcement to the Australian Securities Exchannge.
“We have drilled 300 metres of strike at Prospect 150 and based on our past soil geochemistry program, we may be in an 800 metre zone of mineralisation.
“If it’s typical of our other mineralisation, we would expect Prospect 150 to have multiple zones.”
Geopacific explained diamond hole KDH002 is the first hole drilled in Prospect 150 and the second hole overall in the diamond drill program at Kou Sa.
The results from KDH002 represent the first time that drilling at the Kou Sa project has intersected both high-grade copper and gold mineralisation in the same zone.
Geopacific considers this to suggest mineralisation at Prospect 150 is much different from what it has identified at the 100 and 117 prospects.
The company said portable XRF results it had taken in the field for copper, from another hole testing the area to the south of Prospect 150 identified a 5.3 metre-wide zone of anomalous copper grading 0.19 per cent copper from 49m and a 0.3m intersection grading at 4.95 per cent copper from 61.5m.
Geopacific has interpreted this zone of copper-sulphide mineralisation to be the edge of another parallel zone of veining coincident with the edge of a copper-gold anomaly.
The company said the results highlight the potential of the area to host numerous parallel zones of high grade gold-copper mineralised veining, and work is underway to further test this potential.
