Summary:
The Lafigué deposit resembles a typical shear zone-hosted deposit of the West African Paleoproterozoic greenstone terrane (Man-Leo Shield) and can be associated with the low-sulphide quartz gold deposit model of Laurence J. Drew (Drew, 2003). The deposit is related to the N-S-trending Oumé-Fetekro greenstone belt, and more specifically, to a Birimian age complex of bimodal metavolcanics and meta-volcanoclastic rocks intruded by a series of felsic intrusions. Mineralization is spatially and genetically related to shearing and fluid ingress along zones of competency contrast between different lithologies. There is a further spatial relationship between some mineralization and felsic intrusive bodies. Gold is often free, occurring in quartz-carbonate-tourmaline veins or associated alteration haloes. Zones of shearing and alteration (mineralised or otherwise) can reach 10s of metres thick, pervading the hanging wall and footwall rocks away from recognised lithological contacts.
The Lafigué deposit is a shear-zone hosted gold mineralization, sitting on the eastern side of the Fetekro permit and extends over an area that is 2.2 km long and 1 km wide. The geology is mostly composed of mafic rocks, namely metagabbros/metanorites and metabasalts. A felsic intrusive (granodiorite or tonalite) occurs in the western part of the prospect and several felsic dykes possibly related to the principal body have been observed in various areas. Regional schistosity varies in strike from north ........

Summary:
The Project will make use of conventional open pit truck and excavator operation with the production unit operations (drilling, blasting, loading, hauling, and dumping) carried out by contractor mining personnel and equipment. The mining contractor will be responsible for short term production planning, drilling (production and grade control), loading and hauling. Blasting will be carried out by a specialised blasting contractor that will also be responsible for the supply of explosives.
The saprolite is anticipated to be primarily free-dig, potentially requiring ripping with 14% of oxide material planned for blasting. A low powder factor was estimated for blasting the oxide material, with blasting of oxides mainly consisting of fracturing the harder laterite cap with a low powder factor of 0.32 kg/m³. As the rock strengths increase, blasting will be utilised more regularly within the transitional zone with powder factors estimated at 0.59 kg/m³. All the fresh rock will be blasted with powder factors estimated at 0.76 kg/m³. Production drilling of transitional and fresh material will be undertaken by top hammer drills drilling 152 mm diameter holes.
Mining is envisioned to occur in 10 m benches, with double batters to achieve the final 20 m bench. Mining will occur in 3 to 4 flitches depending on required vertical selectivity. This practise decreases dilution by using selectivity practises utilising smaller loading units for ore loading. Ore and waste wi ........
