Great Quest also holds the 2,149 sq km Kenieti diamond concession in western Mali. The concession covers three known kimberlite pipes: the 0.6 hectare Sakola, 3.0 hectare Dabora and the 5.0 hectare Orange River. A 0.05 carat diamond was previously recovered from the Orange River kimberlite pipe and other diamonds have previously been discovered in alluvium in four separate locations within this concession, including five in one of the areas. All of the diamonds have been documented by the Bureau de Recherche Geologique et Minieres, a French Government agency.
The Kenieti concession covers part of the West Africa diamond corridor, which passes through western Mali. In western Mali, seven of the 30 known kimberlites are diamondiferous. Of the 95 diamonds previously found and documented in the district before 2006, from both alluvial sources and bulk sampling of kimberlite pipes, 19 were microdiamonds and 74 were macrodiamonds. Twenty-one of these macrodiamonds were one carat or greater. Eleven of the macrodiamonds ranged from 30 to 232 carats.
Great Quest's initial program In the Kenieti concession will consist of testing areas of small airborne-magnetic anomalies for diamond indicator minerals in order to locate possible kimberlite pipes.
