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.

BRITTLE FRACTURE ZONE HOSTED DEPOSITS

Tabakoto mine operations currently consist of two underground operations (Tabakoto and Ségala) and open pit (Kofi C) with gravity/CIL processing facilities. During 2015, mining operations at Tabakoto concentrated on the Kofi C open-pit, Tabakoto and Ségala underground from which a total of 10.66Mt of material were mined to deliver 1.37Mt of ore at an average grade of 3.34g/t Au containing 147,500oz to the ROM pad.

The Tabakoto and Ségala underground mines constitute the majority of the ore production at Tabakoto and open pit mining is now essentially used to augment the underground as mill feed.

The Ségala Deposit consists of the Ségala Main and the Ségala North West zones. Open pit mining has taken place at both of these deposits previously. Production is currently planned from underground mining of the Ségala Main zone only. This zone consists of several parallel mineralized structures which run along the length of the ore body and contains the bulk of the currently defined mineralization. The spacing and the thickness of these structures vary. Individual veins, which can be less than a metre thick, are grouped into ore zones which can collectively be up to 25m thick.

The Tabakoto Deposit is accessed from the bottom of an open pit where mining was previously conducted. Underground mine access uses a northern portal to exploit the northwest-trending (“NW”) zones and a southern portal for both the northeast-trending (“NE”) zones and the South ........
