Located to the South of the Loulo Mine, the Kolomba and Moussala permits are contiguous and together they cover 198 km2. Between 2005 and 2007, Robex completed several exploration activities on the permits including the drilling of previously outlined geochemical gold in soil anomalies.
In 2007, a program of geological mapping and two 100 m long trenches was completed on the property. They were centered over an anomalous gold zone located at the crossing of two structures identified on Kolomba, to the North. A North-South trending 660 m wide gold in soil anomaly has been outlined with the geochemical soil survey. One of three zones identified appears to be the strike extension of the Balili and MM-5A anomalies identified on the Kolomba permit. Two active artisanal mining sites have been visited in the Northeast quadrant of the permit. The geology of the Southern half of the permit differs from that of the Northern half and could be more prospective for gold mineralization with five high grade geochemical anomalies distributed within a 1,5 km wide corridor. These targets of interest could rapidly be set for drilling.
