Giyani Metals Corp. Reports High Purity Manganese Oxide Phase 2 Interim Results From Charge CCCV's Digital DNA Program

Giyani Metals Corp. had successful interim results of its High-Purity Manganese Oxide produced from its demonstration plant in Johannesburg, South Africa, received from Charge CCCV LLC from Phase 2 of C4V's Digital DNA Supply Chain Qualification Program. HPMO produced from Giyani's Demo Plant successfully satisfied the Phase 1 qualification criteria under C4V's Qualification Program. As part of Phase 2 testing, C4V assembled multiple single-layer pouch cells using Giyani's HPMO. Interim results confirm that Giyani's HPMO meets CV4 quality assurance standards for Phase 2. Phase 2 completion is anticipated within 60 days, with results and progression to Phase 3 to follow thereafter. Giyani has developed a process flowsheet that enables the Company to produce two battery-grade manganese products, high-purity manganese sulphate monohydrate and HPMO. The technical insights and operational data generated by the Demo Plant operation are being integrated into the definitive feasibility study for the future commercial plant in Botswana. Giyani believes that the learnings derived from the scale and operation of its Demo Plant significantly reduces the technical, scale up, commissioning risks associated with the ramp-up of full-scale commercial operations. The K.Hill DFS remains on track for release this quarter. Using HPMO produced from Giyani's Demo Plant in South Africa, 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. Electrode density is comparable to baseline electrodes and rate testing demonstrates consistent rate and cycling stability across a range of C-rates. 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 approximately six months following the completion of Phase 2. Giyani has shipped both HPMO and HPMSM to multiple potential partners as part of the offtake qualification processes for testing.
