SnapshotMusonoi Project one of the highest grade cobalt mines in the world.

The Jinchuan Group performed further study for deep processing and the feasibility study for further processing copper and cobalt concentrate was completed by ENFI in 2023. Mine design was added with the deep processing facilities endorsed by a revised feasibility study extending such coverage in mid-2023.

The underground project is in construction phase and advancing in line with schedule. The Musonoi mining and processing project has entered the final stage, and the deep processing project is fully kicked off soon.

Jinchuan Group strives to commission the entire system by the end of 2024.

Deposit type

  • Sediment-hosted
  • Breccia pipe / Stockwork


A strike length of 600 m to 700 m has been identified with the deepest drill intersection obtained being 550 m below surface. Mineralisation remains open ended at depth. The mineralisation is typical of that of the Kamoto and KOV Mines with two HG zones.

The mineralised zones consist of talc shales, breccias and siltstones forming part of the meta sedimentary sequence. Copper and cobalt mineralisation is generally in the form of malachite and heterogenite/kolwezite in the oxide portion of the deposit and chalcocite, bornite and carrollite in the deeper sulphide zone. The depth of oxidation is approximately 190 m to 220 m below surface.

The ore body is open ended to depth and no flattening of the dip indicating proximity of the fold closure has been intersected thus far. The solids modelling was extrapolated 50 m east and west of the last drill hole intersection (along strike), and 50 m beyond the last drill hole intersection to depth (down dip).
