TSX-V-listed Manganese X Energy Corporation has been granted a patent for its proprietary manganese sulphate purification process, which is a critical mineral used in the production of lithium-ion batteries for electric vehicles and energy storage systems.

The US Patent Office was the second to grant the patent after recent patent acceptance in South Africa, with authorities in Canada, Mexico and Australia also having been applied to.

Manganese X CEO Martin Kepman says the granting of the US patent for high-purity manganese production marks another significant milestone in positioning Manganese X as a vertically integrated North American supplier of battery-grade manganese.

“This patent expands our global intellectual property portfolio and supports our long-term strategy to supply high-purity manganese sulphate to the rapidly growing lithium-ion battery market. It also adds value as we advance our prefeasibility study of Battery Hill where we are evaluating multiple pathways to optimise technical performance and economics,” Kepman adds.

The company is developing the Battery Hill mine in New Brunswick, Canada, which is considered one of the largest manganese carbonate deposits in North America, while advancing a downstream high-purity manganese processing and commercialisation strategy.
