Kou Sa Project Summary

Geopacific’s Kou Sa Project is a well-funded exploration vehicle in a highly prospective district. With a proven management team, focused strategy and compelling results, exploration success is expected to continue and add to the potential scale of the project.

The Kou Sa Project is located in northern Cambodia’s Chep District, Phreah Vihear province and has excellent discovery potential for deposit (s) of economic grade and tonnage. Drill testing so far has produced zones of high grade mineralisation including; 5m at 128.64 g/t Gold and 4.01% Copper. The Kou Sa Project has only been explored by Geopacific since early 2013 and has continually shown excellent discovery potential for polymetallic deposit (s) of economic grade and tonnage. Modern exploration techniques including systematic geochemistry and geophysics have clearly outlined numerous mineral targets.

Project Potential to be a Large Mineral Field

  • The combination of IP geophysics and geochemistry allows Geopacific to consistently and accurately identify drill targets that yield impressive results such as 36m @ 11.11% Cu eq. from 8m (KRC113)
  • The potential scale of Kou Sa is indicated by areas of red and white which show high chargeability
  • High chargeability is used to identify drill targets resulting in over 80% of holes being mineralised
  • IP geophysics with prospect location (below)
  • Exploration upside potential exists with more than half of the license yet to be explored

The mineralisation at Kou Sa is thought to be derived from a deep intrusive source.  Geochemistry, geophysics and petrology all point to a deep source as the origin of the near-surface mineralisation.  As the intrusive cooled, mineralising fluids under pressure have taken the path of least resistance to the surface.  In places the solutions have hit an impermeable layer and as pressure has built up under the layer, the fluids have moved sideways into the rock units that fracture most easily.  The first fluids emplaced are predominantly copper-sulphides. If the pressure buildup is significant enough to crack the impermeable horizon there is a rapid decrease in fluid pressure that causes the gold and silver solutions to deposit in the area of the pressure decrease.  Therefore, as you move away from the area of the cracking the mineralisation transitions from being gold and silver rich, to gold, silver and copper rich and then to predominantly copper sulphide.  In areas where the seal does not crack, mineralisation is predominantly just copper rich.  There can be multiple episodes of cracking and emplacement of solution, which can considerably improve the grade of the mineralisation.

Kou Sa Project History

The project was originally discovered by BRGM geologists in the 1960’s before the Vietnamese and regional civil wars. No further work was conducted until 2008, when GRD commenced exploration activities.

Kou Sa has had approximately 4,000m of diamond drill undertaken in 2011 and 2012, on several areas within the 158km2 tenement. Only 2,000m of this drilling had been previously sampled using non-standard methods. The available drilling provided a good indication of the type of mineralisation that could be expected at Kou Sa, with excellent near surface massive and semi-massive sulphide intersections being evident. Subsequent sampling by Geopacific’s new Indonesian-based exploration team of all drill core revealed, that the early results were reasonably accurate. In most cases, the entire mineralisation zone had not been previously sampled and therefore the final results generated by Geopacific produced wider zones of mineralisation than first estimated.

Geopacific has signed a sale agreement with Golden Resources Development Co., Ltd (“GRD”) (a South Korean controlled Cambodian company). The sale agreement is an option to acquire an 85% interest in the highly prospective Kou Sa Copper Project in Northern Cambodia. The remaining 15% has been acquired by a subsidiary of Geopacific’s Cambodian partner, The Royal Group.
