Ongoing drilling by Geopacific Resources at the Kou Sa Copper-Gold Project in Cambodia has returned thick, high-grade down-dip extensions to existing mineralized zones and has identified a potential feeder zone.
Prospect 160 is one of the most advanced areas at Kou Sa and is expected to form part of a future resource. Ongoing extensional drilling has identified an extremely thick zone of copper sulphide mineralization that forms the central core of the overall mineralized structure.
The first deep hole into the zone intersected copper sulphide mineralization at least 28 metres thick from a shallow depth. The hole ended in mineralization when drilling conditions caused the hole to collapse. The zone thickens at depth and is open to the northwest.
Recent drilling has returned results of: 28 metres @ 3.37% copper and 5.43 grams/tonne silver for 3.43% copper equivalent, including 16 metres @ 5.08% copper and 7.5 grams/tonne silver for 5.17% copper equivalent; and 20 metres @ 2.08% copper and 7.5 grams/tonne silver for 2.16% copper equivalent.
A further hole drilled up plunge has intersected more than 40 metres of copper sulphide mineralization. This hole ended in mineralization after collapsing due to unfavourable drilling conditions. Assay results for this are expected shortly.
Geopacific’s managing director Ron Heeks said, “Recent drilling at Prospect 160 confirmed our understanding of the style of mineralization in the area allowing us to target drilling into what is a considerably thicker zone of mineralization that plunges to the northwest.
“This thicker zone that appears to be more than 50 metres wide has been intercepted to a true thickness of more than 40 metres. It is open to the northwest and has the potential to extend considerably further. The top of the 40 metre-thick zone is only 40 metres from the surface and dips at a shallow angle of 30 degrees to the northwest.
“Drilling of this zone will continue as a matter of priority with a diamond drill rig being used to test the mineralization at depth. The zone will add considerably to the metal inventory of the project.”
RC drilling will continue to test near-surface mineralization at Prospect 160 before moving to prospects 120 and 190 in coming months. A diamond drill rig currently drilling the potential feeder zone at Prospect 150 will be moved to Prospect 160. The second diamond rig on-site is testing the Prospect 117 area where a new interpretation of the mineralization in that area appears to have been validated.
A new track-mounted diamond rig is being mobilized from Thailand to enable the drilling of deeper diamond holes and improve mobility between drill holes.
