Giyani ships battery-grade manganese samples to offtakers

Giyani Metals Corp., the developer of the K.Hill Battery-Grade Manganese Project in Botswana, has shipped the first shipment of high-purity manganese oxide samples to potential offtakers for testing and qualification from its Johannesburg Demonstration Plant.

Highlights:

• Giyani has produced High Purity Manganese Oxide (HPMO) at its demo plant and shipped samples to potential offtake partners after its March 2025 announcement.
• Production of High Purity Manganese Sulphate Monohydrate (HPMSM) is targeted for Q3 2025, followed by qualification trials with offtake partners.
• Both HPMO and HPMSM are critical precursors for various fast-growing battery chemistries, including LMFP, LMNO, and NMC, used in electric vehicles and energy storage systems.
• Giyani’s ability to produce both HPMO and HPMSM enhances its technological adaptability to meet evolving battery technology demands.
• The Demo Plant is key to de-risking full-scale commercial plant construction in Botswana. It represents a major milestone in scaling up Giyani’s proprietary process—making Giyani one of the few non-Chinese companies to reach this stage.

Commissioning and optimisation of the demo plant have led to:

• Better process understanding for commercial design
• Cleaner HPMO production with reduced waste and emissions
• Discovery of a valuable new by-product.

Charles FitzRoy, President and CEO of Giyani Metals, commented: “The Demo Plant is continuing to meet important operational objectives, with the shipment of HPMO being a major accomplishment that significantly endorses the project and has allowed us to move forward with offtaker testing. In parallel, we continue to progress towards the production of HPMSM and realise the technological and product optionality that will afford Giyani significant advantages in a rapidly evolving battery market. The team on the ground at the demo plant are doing a fantastic job and continue to derisk the planned commercial plant in Botswana through ongoing operation and modifications to the demo plant,“ says FitzRoy.

“The market continues to announce developments in higher manganese content battery chemistries, like Ford and GM’s recent lithium-manganese-rich (LMR) breakthroughs, which contain multiples more manganese than their current nickel-manganese-cobalt (NMC) batteries. New developments in battery manufacture may open up the need for other forms of manganese, and it is vital that Giyani moves with the market. The ability to produce HPMO and HPMSM gives Giyani that edge, and it is clear that there is interest around our project, and we appreciate the incredible support from our stakeholders.”

The company has revised its HPMSM production timeline to Q3 2025, with the Definitive Feasibility Study (DFS) completion in Q1 2026. Construction of the commercial facility is set to begin in 2027, with production ramp-up starting in 2028/2029. This strategic timeline aims to meet the predicted demand increase for battery-grade manganese from 2028 onwards.
