SnapshotKobada is a large gold system in a prolific gold district with numerous near-surface targets with potential for expansion, thanks to soft, free-dig oxide ore, a probable low strip ratio and high 95% oxide recoveries through a standard gravity/CIL treatment plant.

2024 Mineral Resource Estimate (MRE) marks completion of key milestone in Toubani's development of Kobada project.

The MRE update will feed into updated pit optimisation studies and mine design / schedules which will inform the Definitive Feasibility Study (DFS) Update in progress.

Toubani reports that the DFS for Kobada remains on schedule to be completed in October 2024.

Summary:

The Kobada Gold Project is situated on the western flank of the Bougouni Basin, composed primarily of sedimentary rocks with minor tholeiitic volcano-sedimentary intercalations. Gold at Kobada is present in the laterite, saprolite and quartz veins. The terrain is intensely lateritised, with large laterite plateaus covering most of the area. The underlying saprolite is exposed below the plateau boundaries.

The veins occur as quartz-carbonate veined mesothermal, orogenic gold hosted within a greenstone belt. They are located in arenites affected by a geological structure that is oriented northeast along the border of an intermediate intrusive that has basic components.

The Kobada Gold Project comprises an extensive strike area of 8 km and includes the Kobada and Foroko deposits. Kobada is further defined by south, central and northern areas which represent statistically similar gold populations within a conceptual structural framework. Interpretations were generally supported by drilling fences 20–40 m along strike and 20 m down dip in the centre of the deposit, ranging to 80 m centres in extensional drilling.

Kobada mineralisation extends over 5.25 km NNE–SSW strike length. Lode thicknesses for the shear-hosted mineralisation average 30–40 m and hangingwall/footwall veins are 1–15 m in width. Mineralised domains at the Foroko deposit extend over a 2.7 km north–south strike length. Lode thicknesses are highly variable and range from 1m to 10.8m in true thickness. Mineralisation exists from surface and currently extends 340 m from natural surface.

Production

The Kobada Gold Project, when completed, will produce 100 000 oz/a of gold via a conventional gravity carbon-in-leach (CIL) process designed to treat 3 Mt/a of run of mine (ROM) for the first 10 years of production, followed by low gold production as a result of treating low grade ore.
