E25 Files Key International PatentApplications for Low Carbon HPMSM Process

Element 25 Limited (E25 or Company) (ASX: E25; OTCQX: ELMTF) is pleased to announce it has finalised and lodged two key international patent applications in relation to its battery grade high-purity manganese sulphate monohydrate (HPMSM) production process.

Element 25 has lodged these under the Patent Co-Operation Treaty (PCT), claiming priority from Australian Patent Application(s) 2022903576 & 2022903573. The patent applications are expected to provide protection for two key manganese processing steps in the Element 25 flow sheet, which are critical to delivering the advantages of its HPMSM process compared to existing processes currently in production, namely:

• Reduced energy consumption compared to roast reduction processing.
• Reduced reagent consumption compared to traditional neutralisation.

Separation of waste residues in forms that can be used in existing industrial processes, thereby minimising or eliminating waste disposal requirements.

These innovations mean that the E25 process can claim industry-leading low carbon intensity and compete on cost in target markets when compared with existing producers.

E25 expects its patent applications to be processed in 2024.
