SnapshotThe Kiaka Project comprises the Kiaka Main and Kiaka South open pits. Kiaka’s construction progress remains on schedule and budget.

Major procurement and installation contracts finalised included the structural, mechanical and piping (SMP) wet and dry areas, as well as the high voltage mains powerline and substations where the transmission line survey was finalised and pegging of the towers commenced. Overland HDPE piping package was also awarded.

Major equipment arriving on site includes crushers, thickener, CIL tank steel, steel framed sheds, structural steel, SAG mill shells. CIL tank installation underway.

Summary:

The project is located at the intersection of the Tenkodogo belt and the Markoye Fault Zone within Lower Proterozoic rocks of the Birimian Orogeny. Amphibole-rich mafic volcanic rocks are predominant in the lower (southern) portion of the deposit area, overlain by a sequence of clastic sediments. Several quartz-feldspar porphyritic sills intrude through the sequence at the northern end, the most significant of which is 90m thick, interpreted to be an important rheological barrier to gold mineralisation. At least two generations of postmineralisation mafic intrusions occur: steeply dipping, medium to coarse grained diorite dykes up to 80m wide, and fine grained dolerite dykes 2-3m wide, with well defined, sharp contacts. Structural patterns are the product of protracted northwest-southeast directed shortening, producing a major F2 antiform several hundred meters wide, that is thought to be a primary control on localisation of gold mineralisation, evidenced by steep northeasterly plunging mineralisation zones.

Gold mineralisation at Kiaka occurs within the subvertical southwest dipping Kiaka Shear Zone (KSZ), comprising an anastomosing network of ductile to brittle-ductile shears, localised along the axial surface of the Kiaka antiform. The KSZ ranges from 100-260m, with a strike length of approximately 2.3km. Gold mineralisation exhibits both disseminated and vein-related characteristics, and is spatially associated with fine grained disseminated pyrrhotite, lesser pyrite and race chalcopyrite and arsenopyrite. Higher gold grades are frequently associated with the presence of quartz, both as veins, and wall rock silicification.

Known mineralisation at Kiaka Main extends along strike for approximately 2km and consists of multiple broad lenses up to and in places exceeding 200m wide. Mineralisation has been drilled up to 600m in depth. At Kiaka South, mineralisation exists up to 500m strike and 200m deep and is less well developed in terms of overall continuity than the main zone. Individual lenses are up to 200m in strike and up to 35m wide. Mineralisation at both deposits remains open at depth.
