|Koro Gold Project, Burkina Faso|
The Koro Gold Project is accessible via a bitumen highway linking Ouagadougou and Ouahigouya with access within the project possible throughout the year (including rainy season) via all-weather formed gravel roads and village tracks.
Summary of geochemical auger drilling programme results
The active Arbole Sud-Titanguen artisanal mining site located to the north west of the Koro Gold Project has yielded the most encouraging results.
Original auger drilling over a 100x20m grid has successfully defined an anomalous area (350 x 150m) with an apex defined by a >300ppb value from the north east to the south west of the artisanal mining site delineating a trend consistent with major shears defined by aeromagnetic survey imagery.
Significant gold anomalies with values up to 11,000ppb within the supergene oxidation area have been identified in the first 20m from surface, in two auger drill hole sections, that are typically associated with gold microstockworks or veinlet networks and disseminated mineralisation.
The 400x400m regional auger programme at the Koro Gold Project has defined the presence of some large gold anomalies ranging from 5 to 30ppb Au. Aeromagnetic imagery and broader spaced auger sampling suggest this target zone may stretch up to 7km from the Arbole Sud-Titanguen artisanal mining area. The identification of a second artisanal mining site at Bouria to the SW of Arbole Sud-Titanguen also provides a strong indicator of this.
The mineralisation characterised by an organised network of quartz veins and veinlets in shear zones with disseminated sulphides occurring in zones of strong ductile deformation. Gold mineralisation is also preferentially concentrated along the contacts between the lithological units.
