The gold deposits of the Tabakoto project are dominantly hosted in the Birimian, turbiditic sedimentary rocks of the Kofi Formation. These rocks have been intruded by multiple generations of dikes and sills ranging from felsic to mafic composition. The entire package of rocks have been deformed and metamorphosed during the Eburnean orogeny. While individual structures associated each of the deformational events can host mineable deposits, multiple generations of structure enhances the probability of mineable ore.

The deposits can be further divided into three broad types as follows:
- Shear Zone hosted (Ségala and Ségala NW);
- Fracture and cross structure hosted (Dar Salam, Tabakoto, Dioulafoundou and Kofi C), and;
- Intrusive hosted (Djambaye II).

SHEAR ZONE HOSTED DEPOSITS
The Ségala and Ségala NW deposits are considered to be part of a structurally controlled alteration and mineralization system that is hosted by the core of an isoclinal anticline whose axial trace trends ESE (approx. 110°) and dips steeply to the south at approximately -80°. The anticline is made up of somewhat deformed and altered meta-sediments (greywacke and argillite) that display variable intensities of alteration of chlorite, carbonate, sericite, sulphide and silica. A series of quartz stringers and veins intrude this package.

Production comes from both underground and open pits:
– Tabakoto Underground;
– Segala Underground;
– Kofi B Open Pit;
– Tabakoto North Open Pit.

Mining activity is by owner mining.

There are five veins being exploited by means of underground mining methods. These are:
- The Ségala Main Zone, where transverse long hole stoping is preferred and either cemented rock fill (“CRF”) or unconsolidated rock fill is utilized to enhance local and overall ground stability;
- The Ségala Footwall Zone, where longitudinal long-hole stoping is the design together with cemented rock fill or unconsolidated rock fill;
- The Tabakoto North West veins where there are more than five closely spaced veins. Selective longitudinal long-hole stoping is used to extract ore from the top down without using fill;
- The Tabakoto North East veins where two main veins are separated by about 10m and long hole stoping is also used to extract ore from the top down without fill, and;
- The Tabakoto South vein, which is relatively long and narrow with better grades. Long-hole stoping moves from the bottom upwards as opposed to a top down approach. Waste fill is also used in this instance.

Mining – Segala Underground
- Ségala is at full production producing just over 40ktpm from underground.
- One access portal, and two ventilation portals near the bottom of Segala open pit. Decline access is from a portal located 25 m a ........
