The West Kenya Project is made up of two greenfield deposits, the Isulu and Bushiangala Prospects and includes mineral rights which cover an area of 1,161 km2.
In 2023, the West Kenya Project Feasibility Study workstream, led by an internal owners team, will continue. The team will focus on developing and evaluating mining conceptual models, which marks an exciting initial step towards converting the West Kenya Project from an exploration project to a producing entity. |

Summary:
The Western Kenya Project area is located in the County of Kakamega in western Kenya.
The Liranda Corridor is located on the eastern most margin of the Busia-Kakamega Belt. Here rocks form a broad synclinal structure intruded in the centre by granitoids and dioritoids, informally termed the Kakamega Dome. The Liranda Corridor is situated on the eastern limb of this synclinal structure within a 12 km structural zone known informally as the Liranda Corridor. Lithologies of the Isulu and Bushiangala prospects include sediments, iron-rich basalts, ultramafic volcanic rocks, gabbros, dolerites and small felsic intrusions. The mafic volcanic unit also includes thin layers of sulphidic carbonaceous interflow mudstone.
The Isulu and Bushiangala prospects mineralisation are classified as orogenic, shear-zone-hosted quartz-carbonate vein subtype. Mineralisation of this sub-type consists of quartz-carbonate veins and veinlet arrays associated with Mg-Fe carbonate alteration and sulphidation, which are developed within shear zones and their splays, within competent rock units. Mineralisation is concentrated in zones of enhanced fluid flow, such as jogs or changes in strike along the larger-scale fault zones.
The main zones of mineralisation at Isulu extend up to 240m along strike. The resource estimate (Phase 1) generally includes mineralisation down to 250m depth.
At Bushiangala the mineralisation extends over 270m along strike in the NNW-SSE ........
Mining Methods
- Truck & Shovel / Loader
- Longhole open stoping
- Backfill
Summary:
A pit optimisation study has been undertaken for the Deposits to determine the potential for open pit mining at the Project. Based on this assessment an initial open pit at each of the Deposits has been shown to have potential. Following pit optimisation results, a pit shell has been selected for each deposit. Open pit mining will be by standard drill, blast, truck and shovel methods. Open pit mining is expected to benefit from free dig mining of oxide resources.
Underground mining will commence after open pit mining, with the proposed mining method for the Deposits being LHOS with backfill.
The envisaged underground mine will be accessed by two portals, at Isulu and Bushiangala, from which declines will be driven down at each deposit.

Reserves at February 22, 2023:
The Mineral Resource has been reported at a minimum cut-off grade of 0.7 g/t Au for both the oxidised rock and fresh rock, which was assigned to reflect current commodity prices, geometry of mineralised zones and comparison with the analogous operations.
