Deposit Type

  • Porphyry
  • Vein / narrow vein


Summary:

The Bissa and Bouly gold deposits all occur within an approximate 90 km NW-SE zone, comprising Birimian volcano-sedimentary rocks of the Boromo greenstone belt. The belt consists of mafic volcanic rock, minor felsic volcanic rock and extensive sedimentary units, intruded by Eburnean granitoids, all of which have undergone incipient to low greenschist facies metamorphism (Huot and Sattran, 1987).

The Bouly deposit, approximately 9 km east of the Bissa-Zandkom corridor, is hosted by shear zones within metamorphosed metavolcanics, diorites and porphyritic diorites. The volcanosedimentary sequence is well foliated, with a NE-SW striking fabric. The meta-volcanics are intruded, and mostly replaced, by later diorite, granodiorite and porphyritic diorite bodies, which are not well foliated except in areas where extensive shearing has occurred. As per the BokenZandkom corridor, two phases of deformation are recognised. The earliest deformation phase is associated with NW striking, moderately SW dipping thrust structures. The second deformation phase is associated with NE striking, steeply SE dipping strike slip structures.

Mineralisation at the Bissa and Bouly deposits is primarily orogenic and structurally controlled, with a secondary lithological control. The most significant mineralised zones are associated with anastomosing networks of quartz and quartz-carbonate veins (or stacked, parallel “arrays” of veins) developed within major brittle-ductile shear zone ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Bouly operation extracts material from multiple open pits. The ore is hauled to the heap leach pads, while the waste is hauled to the waste dumps. Production is undertaken through conventional drilling, blasting, loading and hauling processes. There are currently 16 CAT 777 90 t haul trucks at Bouly which are shared with the Bissa operation. There are two PC2000s and two CAT6015s at Bouly, and CAT 993 front-end loaders (“FEL”) are used on the stockpiles. The Bouly open pit is currently formed from three small to medium size open pits that will eventually form a single pit as mining progresses. The Bouly pits are currently mining oxide although as the pits develop, transition and fresh material will also be mined. The ramps have been designed at a gradient of 10% at 23.5 m width for dual lane and 15 m to 17 m for single lane access at the pit bottom. The mining benches are 8 m high and are mined in 4 m flitches.
