Manganese X Energy Corp. reports on the development of its Battery Hill manganese project in New Brunswick, Canada, and its strategy to produce high-purity manganese sulphate for lithium-ion batteries used in electric vehicles and stationary energy storage. Recurring updates cover prefeasibility study work, geotechnical drilling, metallurgical process optimization, engineering and environmental consultants, and the project's role in North American critical-minerals supply.
Company news also covers intellectual property for proprietary manganese sulphate purification, including patent activity in major jurisdictions, as well as governance changes and capital-structure matters. The company's disclosures frequently connect Battery Hill with downstream battery-grade manganese processing and commercialization efforts.
Manganese X Energy (MNXXF) has joined an NRC-led cathode research collaboration, providing a 10-kilogram sample of Battery Hill high-purity manganese.
The agreement, dated August 18, 2026, includes E3 Lithium, NiVolt Technologies and POSCO America. The CA$632,111 project incorporates Canadian mineral feedstocks into lithium-manganese-rich cathodes, the battery materials that store and release lithium. The NRC will produce and test materials and coin cells; POSCO will conduct technical verification and performance assessment.
Manganese X's contribution is valued at approximately CA$116,325, and the NRC's at approximately CA$155,500. Completion is scheduled for March 31, 2027. The agreement identifies Battery Hill's proprietary processing flowsheet as Manganese X Background Intellectual Property.
