Geopacific Resources managing director Ron Heeks said: " The drilling has again produced spectacular gold, silver and copper intersections and considerably increased our understanding of the style of the Prospect 150 mineralisation.
"Some of the mineralised zones identified are still open so a further drilling program will be required to fully delineate these. We are currently working towards an initial resource for Prospect 150 later this year."
The RC drilling, guided by Induced Polarisation ( IP) geophysics data, was designed to provide greater detail on known zones and extend previously reported mineralised boundaries with the objective of allowing the company to calculate an initial resource for Prospect 150 later this year.
A deep dipole – dipole IP geophysics survey was also recently completed over the Prospect 150 area to identify lateral and de p th extension s to the current ly known mineralisation. This survey , when added to the recently completed surface IP survey that accurately del ineated the surface expression of the Prospect will help design the next round of drilling.
The main 400m strike of the prospect has now been nominally drilled on a 40m by 40m pattern down to a depth of 70m. Future drilling program s will extend open zon es, look to confirm deeper ‘ feeder ‘ mineralisation and infill some areas down to a nominal 20m by 40m spacing prior to a resource being calculated.
This section was drilled in detail to allow for an accurate interpretation of the nature of the mineralisation to be made. The zone dips at approximately 30 degrees to the north and is also interpreted to plunge at about the same angle to the west. There is evidence of several offsetting structure s through the zone which need to be better understood before the zon es can be extended further west and north. On some sections the most northerly holes drilled in the zone have intersected mineralisation that will require more extensional drilling.
It is believed that a feeder zone could exist below the flatter zones. This may have been intersected in some sections as represented by the areas of very high grade. The orientation of these zones is not clearly understood and it is hoped that the deeper IP survey will assist with delineating these areas.
Results from this round of drilling are from 4 metre composites taken as a first pass sampling step. The significant intervals are currently being split and analysed at 1 metre intervals.
The Prospect 150 area combined with the nearby Prospect 160 are the most advanced of the areas at Kou Sa and with the excellent grade and recently released very high metallurgical recovery are likely to provide the initial feed for a flotation concentrate plant.
Drilling is continuing in other areas to test IP anomalies to allow them to be prioritised for further detailed resource definition work. As part of this program the Prospect 170 and 19 0 areas are currently being tested and initial results from these new zones should be available shortly.
Surface and deep IP is al so continuing to test new areas to generate furthe r target zones for drill testing.
