5 March 2025
Giyani Metals Corp. (TSXV: EMM) has produced its first batch of high-purity manganese oxide (HPMO) from the K.Hill project in Botswana.
The material, a precursor for the production of high-purity manganese sulfate monohydrate (HPMSM) used in EVs and energy storage systems, was produced at the company’s demonstration plant in Johannesburg.
According to Giyani, HPMO samples are expected to be shipped this month to prospective offtake partners. Shares of Giyani rose 6.25% Monday morning in Toronto, giving the company a market capitalisation of $23.3 million ($16.2 million).
HPMO is becoming the preferred precursor for lithium-manganese-iron-phosphate (LMFP) and lithium-manganese-nickel-oxide (LMNO) batteries. While HPMSM remains the preferred precursor for nickel-manganese-cobalt (NMC) batteries, both HPMO and HPMSM can be used to produce LMFP and LMNO batteries.
The K.Hill project
Giyani said its demonstration plant remains on track to produce HPMSM during Q1 2025. Subsequently, a commercial plant is expected to be constructed in Botswana.
The company is currently working on a definitive feasibility study, which is expected to be completed in 2025. The K.Hill project is estimated to contain over 2.2 million tonnes of manganese oxide resources.
A preliminary economic assessment in 2023 gave the K.Hill project a base case post-tax net present value (discounted at 8%) of $984 million and an internal rate of return of 29%. Over a projected 57-year mine life, the project is expected to produce over 3.5 million tonnes of HPMSM.
