Giyani Metals, developer of the K.Hill Battery-Grade Manganese Project in Botswana, has started production at its demonstration plant in Johannesburg, South Africa.
Giyani Metals has developed a hydrometallurgical process to produce battery-grade manganese (HPMSM), a lithium-ion battery cathode precursor material.
The production ramp-up is underway, with the plant progressing toward its initial output of battery-grade manganese. Significant advancements were made in hot commissioning during January 2025. The first product samples are expected to be produced within the first quarter and will be sent to potential off-takers for qualification trials.
The demonstration plant, consisting of nine process modules, is designed to refine and enhance the commercial plant’s final design in Botswana, which will be constructed next to Giyani’s fully owned manganese ore sources. Built at a 1:10 scale of the planned facility, the demo plant’s laboratory, procedures, and methodologies will be directly transferable to the full-scale commercial operation.
“The Demo Plant is an essential component in Giyani’s long-term strategy to deliver high-purity battery-grade manganese to the EV market. This production capacity establishes a strong foundation for Giyani to engage with potential off-take partners, as the continuous process flow of the Demo Plant will allow the team to target steady-state operations over extended periods, proving Giyani’s ability to produce consistent battery-grade manganese and satisfy off-take requirements. This continuous operation at pre-commercial scale also provides critical information for understanding how the Commercial Plant will respond.”
Charles FitzRoy, President and CEO of the company.
Giyani Metals Corp. is a Canadian-based mineral resource company focused on developing high-purity manganese for the electric vehicle (EV) battery market. The company’s flagship project, the K.Hill Battery-Grade Manganese Project in Botswana, aims to become a leading producer of high-purity manganese sulfate monohydrate (HPMSM), a key component in lithium-ion batteries. Giyani has developed an innovative hydrometallurgical process to produce battery-grade manganese efficiently and sustainably. With a fully owned manganese ore source and a demonstration plant in Johannesburg, Giyani is advancing toward commercial-scale production, positioning itself as a key supplier in the global EV battery materials supply chain.
