RETRANSMISSION: Manganese X Energy Provides Battery Hill High-Purity Manganese Sample for NRC-Led POSCO LMR Cathode Research Project

(TSXV:MN) (FSE:9SC) (OTCQB:MNXXF) Manganese X Energy Corp. announced it has entered into a collaborative research agreement dated August 18, 2026, with the National Research Council of Canada (NRC), E3 Lithium Ltd., NiVolt Technologies Inc., and POSCO America Corporation to develop and demonstrate lithium-manganese-rich (LMR) cathode materials using Canadian critical-mineral feedstocks. Manganese X is providing a 10-kilogram sample of high-purity manganese for research and testing. The high-purity manganese sulfate monohydrate (HPMSM) used in the project is produced from Manganese X's Battery Hill manganese ore in Woodstock, New Brunswick, Canada. The collaborative Canadian research and development project is valued at CA$632,111 and is led by the NRC. The Woodstock area of New Brunswick, including Battery Hill, is described as representing the largest manganese resource in North America. Kemetco Research Inc. supplied 10 kilograms of Battery Hill HPMSM for the research program. POSCO will conduct technical verification and performance assessment of the Canadian precursor and cathode materials at its R&D facilities. The NRC will integrate Canadian manganese, lithium, and nickel feedstocks to produce precursor cathode active material (pCAM), cathode active material (CAM), and coin cells, which will undergo characterization and electrochemical performance testing, including evaluation of capacity retention and stability. Manganese X CEO Martin Kepman stated that the NRC was instrumental in organizing the collaborative research agreement. POSCO is described as a major global industrial and materials organization with an expanding rechargeable-battery-materials business. POSCO Future M, an affiliate, has announced development of LMR cathode materials. Manganese X's contribution to the project is valued at approximately CA$116,325, while the NRC's contribution is approximately CA$155,500. The project is scheduled to be completed by March 31, 2027, and is also supported through separate NRC funding arrangements for eligible participants. The project aims to demonstrate an integrated pathway from upstream Canadian critical-mineral production through midstream battery-material manufacturing. Manganese X is advancing its Battery Hill Manganese Project in New Brunswick with the objective of producing battery-grade HPMSM for the North American battery supply chain. E3 Lithium is advancing its Clearwater Lithium Project in Alberta. NiVolt Technologies is focused on nickel processing and domestic battery-material supply capabilities. The NRC provides advanced research capabilities in battery materials, chemistry, and electrochemical technologies. POSCO will conduct technical verification, performance assessment, and industrial qualification activities. Manganese X's proprietary HPMSM beneficiation and processing flowsheet for Battery Hill is identified as Manganese X Background Intellectual Property under the agreement. The scientific and technical information in the release was reviewed and approved by Perry MacKinnon, P. Geo., Vice President of Exploration of the Company, who is a Qualified Person as defined in National Instrument 43-101.

RETRANSMISSION: Manganese X Energy Advances to Final Phase of C4V Battery Qualification Program Following Initial Performance Validation

(TSXV: MN) Manganese X Energy Corp. announced that its high-purity manganese material has advanced to Phase 3, the final stage of Charge CCCV LLC (C4V)'s battery qualification program: Multi-Layer Full Pouch Cell Evaluation. The Phase 3 evaluation is expected to take approximately six months, with interim performance updates anticipated during the program. The company's battery-grade manganese material is sourced from its Battery Hill project, one of the largest manganese deposits in North America, which is at prefeasibility stage and located near Woodstock, New Brunswick, Canada. Phase 2 testing with C4V delivered strong results, with 70% capacity retention after 4,600 cycles, indicating better cycle life than conventional NMC-based EV battery chemistries and comparing favourably with Lithium Iron Phosphate (LFP) and Lithium Manganese Iron Phosphate (LMFP) chemistries. The Phase 3 testing is evaluating the Battery Hill material in multilayer pouch cells (3Ah design) to meet end-user product requirements. The company projects that successful results from this final phase will further validate the material's performance in advanced battery designs, paving the way for commercial adoption. Manganese X's mission is to advance its Battery Hill project into production and become the first public actively traded manganese mining company in Canada and US to commercialize EV compliant high purity manganese.
