TSX-V-listed Giyani Metals has reported that successful interim results for high-purity manganese oxide (HPMO) produced from its demonstration plant in, Johannesburg, South Africa, have been received from US battery technology leader Charge CCCV (C4V).

The results are from Phase 2 of C4V’s Digital DNA Supply Chain Qualification Program.

Using HPMO produced from Giyani’s demo plant, C4V is continuing long cycle life testing on multiple single-layer pouch cells as part of Phase 2 testing of its Digital DNA Supply Chain Qualification Program.

Interim results indicate that Giyani’s HPMO meets C4V’s quality assurance standards.

Giyani says electrode density is comparable to baseline electrodes, adding that rate testing demonstrates consistent rate and cycling stability across a range of C-rates.

The company explains that cells incorporating Giyani’s HPMO are also showing capacity retention comparable to baseline cells during long cycling, with overall stability looking encouraging.

Phase 2 testing is ongoing, with further evaluation of the cells using Giyani’s HPMO until the cells reach 80% retained capacity which is expected within 60 days.

Phase 3 consists of multi-layer pouch cell testing with similar checks as Phase 2 and is expected to take about six months following the completion of Phase 2.

Meanwhile, Giyani notes that the definitive feasibility study (DFS) for the K.Hill battery-grade manganese project, in Botswana, is on track for release during this quarter.

Giyani says discussions are ongoing with a number of potential strategic partners to support Giyani’s strategic goals and objectives.

Through the development and operation of the demo plant, Giyani says it has developed a process flowsheet that allows the company to produce at scale, two battery-grade manganese products – HPMO and high-purity manganese sulphate monohydrate (HPMSM).

This will enable the company to adapt and supply a broader range of future battery chemistries.

Giyani notes that it has shipped both HPMO and HPMSM to multiple potential partners as part of the offtake qualification processes for testing.

Giyani received a letter of intent in June 2025 from the Export-Import Bank of the US for up to $225-million in financing to support the construction of the project.

“Building on the success of Phase 1, the interim results from Phase 2 of C4V’s Qualification Program look promising, with HPMO samples produced from our demo plant successfully meeting the necessary quality assurance requirements set by C4V, a leading US battery technology company.

“This is another step forward to securing independent third-party validation of the quality of our manganese product and we look forward to the completion of Phase 2 once the cells have reached 80% capacity retention.

“In parallel, I am pleased to report that our DFS remains on track for completion this quarter and we look forward to announcing the results to the market,” says Giyani interim executive chairperson Nigel Robinson.

“We are encouraged with the positive interim results from Phase 2 of our Digital DNA Qualification Program with Giyani Metals.

“Their HPMO product is showing promising performance during our internal evaluation and aligns well with our material and electrochemical standards. We look forward to completing Phase 2 and advancing through Phase 3 of qualification and further strengthening our collaboration,” adds C4V supply chain VP Baasit Ali.
