The Yaouré Deposit is a structurally controlled, greenstone hosted gold deposit similar in nature to many exploited elsewhere in the Birimian terranes of West Africa.

Gold mineralisation is accompanied by traces of molybdenum, tungsten, antimony, bismuth and tellurium indicating that the mineralisation may have affinities with the reduced intrusion-related gold systems (IRGS). The predominance of structural controls and association with carbonatisation, sericitisation and silicification, however, are characteristics that more clearly point to its classification as an orogenic, mesothermal gold deposit.

Govisou and Angovia 2 deposits are hosted by Palaeoproterozoic Birimian Supergroup rocks of the Bouaflé Greenstone Belt.

Govisou gold deposit is hosted by a diorite intrusion surrounded by metabasalts. Mineralisation is thought to be associated with both NE and NW striking, subvertical structures but forms a diffuse volume that is almost circular in plan view, about 90m in diameter and plunging at about 60 degrees toward the NNW. Gold is associated with low concentrations of finegrained disseminated pyrite and phengite alteration. Quartz veining is rare.

Angovia 2 deposit comprises gold mineralisation associated with pyrite disseminations and veinlets hosted in chloritecarbonate-silica altered metabasalts. The deposit strikes E-W in an anastomosing shear zone and extends over about 550m strike, with mineralisation controlled by brittle-ductile shears that mainly dip south at 50-60 degrees. Subsidiary northdipping structures also appear to occur.

The Govisou pit shell is approximately 300m in diameter and extends to a maximum depth of 120m. The Angovia 2 pit shell extends over 600m strike E-W and to a maximum depth of approximately 120m.

The chosen method of mining is conventional open pit mining utilising hydraulic excavators and trucks, mining bench heights of 5 m with 2.5m flitches to minimise ore loss and waste rock dilution.

Inter-ramp pit slopes are 40 to 60 degrees varied by material weathering level and wall sector. Inter ramp slopes are excluding ramp but including berms spaced at between 10 and 20 metres vertically and berm widths of 5 to 7 metres.

Pit ramps have been designed for a 100-tonne payload truck fleet and are set at 24 metres (dual lane) to 16 metres (single lane).

Minimum mining width of 40 m was generally applied to the pit designs.

The Yaouré processing plant uses crushing, grinding, gravity and cyanide leaching to extract gold. The plant has a nominal capacity of 3.5Mtpa. The technology used in the processing plant is well proven, and the plant has been operating successfully since November 2020.
