High-Purity Manganese Output Targets EV and Energy Storage Markets

Giyani Metals, a Canada-based mining company, has successfully produced its first battery-grade manganese at its South African demonstration plant, the company announced today. The milestone marks a key step toward supplying the electric vehicle (EV) and energy storage system (ESS) markets with high-purity manganese materials.

Production began in February, following the commissioning of the Johannesburg-based demonstration facility, which started in October last year. The plant produced high-purity manganese oxide (HPMO), a precursor for high-purity manganese sulphate monohydrate (HPMSM) used in EV batteries.

Although Giyani initially aimed to begin production in Q4 2023, water and power availability challenges in December caused delays. Nonetheless, the facility is now operating and preparing for the first HPMSM output in Q1 2025.

Commercial Production Planned for Botswana

The South African demo plant is designed to derisk and validate the process for Giyani’s planned commercial plant in Botswana. This larger facility will supply automotive OEMs with critical battery-grade manganese, improving global supply chain resilience.

As demand grows for sustainable and regionally diversified manganese sources, Giyani’s progress supports the strategic shift away from China-dominated processing. The company is positioning itself as a key Western supplier of battery-grade manganese for next-generation lithium-ion batteries.
