Geopacific Resources believes that using the latest geophysical survey techniques to guide future drilling at the Kou Sa Copper Project will likely lead to significant increases in high-grade copper resources. It says Induced Polarization (IP) geophysics is the silver bullet to finding new ore zones.

Recent scout drilling, guided by IP, has shown the technique can accurately identify sulphide mineralization in multiple zones. Geopacific believes this could accelerate the discovery of new ore zones at Kou Sa and rapidly increase the project’s overall resource base.

The latest drilling at Kou Sa has identified two new high-grade zones at Prospect 128 and helped confirm a new zone to the west of Prospect 100.
Guided by the IP geophysics data a 4km long trend of mineralisation between Prospects 160 & 128 with multiple discrete sulphide anomalies has also been identified.

Fifteen holes were recently drilled to test several anomalous zones identified by the IP. These holes were widely spaced and designed to provide an initial, rapid assessment of the IP survey results. Every hole intercepted either significant mineralization or zones of anomalous sulphide mineralization that have the potential to host economic ore along strike.

Best results are 4.6 metres from 20.4 metres @ 6.43% copper equivalent including 3.3 metres from 21.8 metres @ 8.79%; 7.0 metres from 58.1 metres @ 2.88% including 5.2 metres from 59 metres @ 3.67%; and 14.4 metres from 31.1 metres @ 2.59% including 5.0 metres from 40.5 metres @ 5.31%.

Geopacific’s managing director Ron Heeks says, “We have confirmed that the ‘silver bullet’ of exploration techniques at Kou Sa is the IP geophysics. Across the central portion of the licence every hole drilled into an IP anomaly has encountered a zone of sulphide mineralization. Some of the zones have produced ore grade intersections with the potential to add significantly to the current metal inventory of the project.

“We have now positively demonstrated that the IP accurately outlines copper and other associated base metal zones across the central portion of the Kou Sa licence. The IP has also demonstrated that the zone between Prospect 160 and 128 is contiguous over at least 4km of strike, all of which will require further drilling. The upside to the project is becoming very large.”

A large portion of the central licence area has now been covered with IP with most of the remainder to be in-filled as part of the ongoing survey.
