Imbo Licence – Prospects/Targets
The Kitenge Prospect, situated approximately 4 km southeast of the Adumbi Prospect. Colonial-era work on the Kitenge Prospect identified a parallel series of auriferous quartz veins up to about 2.0 m wide. Of these quartz veins, one is dominant and it is hosted in a northwest–southeast trending shear zone and appears to have been the main focus for gold exploitation by the Belgians from both open pit and underground mining.
A compilation by the Royal Museum for Central Africa, Tervuren, Belgium (2007) of historical records indicates that the Kitenge mine operated from 1938 to 1955 and produced some 65 000 oz of gold from surface and underground exploitation.
Diamond drilling in 2010 completed five holes, targeting the shear zone and quartz vein exploited by the Belgians, for a cumulative 1711.45 m. In addition a road cut was channel sampled over a continuous length of 139.0 m. The auriferous gold vein and its host shear zone were explored and confirmed over a 1.0 km strike length at intervals from 160 m to 480 m apart. These holes were collared on the southwest side of the Belgian workings and drilled at -50° on a magnetic azimuth of 040°.
Kitenge Prospect dominant quartz vein is hosted within sheared clastic metasedimentary rocks (greywacke) interbedded with black shales. This shear zone is herein referenced as the Kitenge Shear Zone (“KSZ”). KSZ has been mapped along a northwest–southeast strike orientation over a length of about 2 km. It is parallel with ASZ, and geophysical interpretations, coupled with field verification, indicate that a series of left lateral north trending faults has resulted in offsetting KSZ about 500 m northeast from ASZ which is the same structure.
The Kitenge gold mineralization is associated with a sulphide assemblage of pyrite, pyrrhotite, arsenopyrite and minor chalcopyrite predominantly occurring on fracture/shear foliation planes within the dominant quartz vein. In addition, the mineralization assemblage also occurs with other parallel quartz veins and in highly silicified, sericitized and locally chloritized clastic metasedimentary rocks predominantly on the hangingwall of the KSZ but also on the footwall side.
The gold intersections obtained in the 2012 Kilo drill holes and road cut, presented from northwest to southeast, are listed in the table following.
