Giyani Metals, developer of the K.Hill Battery-Grade Manganese Project in Botswana, has announced that it has successfully produced High Purity Manganese Sulphate Monohydrate (HPMSM) from its Demonstration Plant (Demo Plant) in Johannesburg, South Africa in September 2025.
Highlights:
Successful production of HPMSM from the Demo Plant in Johannesburg, South Africa, marking a significant milestone for the Company.
HPMSM off-taker qualification trials will now commence.
Following the successful production of High Purity Manganese Oxide (HPMO) in Q1 2025, Giyani has now proven its dual product offering capability which positions the Company to supply its products to a broad range of potential future battery technologies and keep pace with the rapidly evolving battery market.
Giyani’s Demo Plant has provided invaluable information and has derisked the final optimized process flowsheet which will now be carried forward into the design and operation of the full-scale commercial plant in Botswana.
Outlook:
The Company’s focus over the next six months will now be:
To complete the Definitive Feasibility Study (DFS) to NI 43-101 standards. This remains on track for completion by end Q1 2026.
Ongoing qualification of Giyani’s HPMSM and HPMO product.
Nigel Robinson, Interim Executive Chair of the company, commented: “Achieving first production of HPMSM in Q3 2025 represents a significant milestone for the Company. The Demo Plant has been invaluable in informing the new optimized process flowsheet, developed by Giyani, over the past several months. We will now incorporate the learning points and process changes into the DFS which remains on track for completion in Q1 2026. This significant milestone will also allow us to commence the off-taker testing phase for HPMSM with HPMO qualification already well underway. With the successful production of both HPMSM and HPMO, we have demonstrated our dual product offering capability, placing us in a strong position to supply the dynamic and evolving chemical requirements of the battery and energy storage market. I would like to take this opportunity to thank all the team for their dedication and hard work in achieving this milestone.”
