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 ........

The Kiaka Gold Project is comprised of the Kiaka Main and Kiaka South deposits, with over 98% of the Ore Reserve contained in the Kiaka Main deposit.

The main ore zone is characterised by a mineralised corridor 100m to 260m wide and has a drill defined strike length of approximately 1.5km. Within this are higher grade lenses ranging between 5m and 50m wide, with good continuity for 100m to 800m along strike and 50m to >400m downdip. These lenses are hosted within a lower grade halo mineralisation within the mineralised structural corridor. The mineralised corridor is flanked by a number of sub-parallel mineralised structures some 2m to 20m wide.

The main portion of the ore body is amenable to exploitation by open pit mining methods. As such the mining study has been based on conventional open pit mining methods with run of mine ore being directly fed to the crushing circuit. This study has been based on having a contractor to execute the mining operations utilising a combination of Caterpillar 6015 (140t class) and 6020 (230t class) hydraulic excavators matched to Caterpillar 777 (95t class) dump trucks. Drill and blast will be required from near surface. Drill and blast parameters have been selected based on the relatively hard rock mass qualities and the required selectivity for the mining of the ore. Given the broad mineralised zone a portion of the blasting will be able to be undertaken on 10m benches with more selective zones blasted on 5m benches ........
