Green Battery Minerals Reports Independent Lab Results of Volt Carbons Dry Separated Graphite from Berkwood Graphite Project
Green Battery Minerals Inc. (" Green" or the "Company") (TSX-V: GEM, FSE: BK2P, WKN: A2QENP OTC: GBMIF) is pleased to announce the independent lab results from Prographite GmBH, assessing the qualities of dry separated Graphite, extracted from the Berkwood bulk sample by Volt Carbon Technologies Inc. at its mineral processing facility.

ProGraphite GmbH, based in Germany, was contracted by GEM to analyze a 125g graphite sample (L#955) provided by Volt Carbon Technologies Inc. on July 1, 2024. The sample's particle size distribution was determined to be mostly -50+80 mesh. Test results indicated low moisture and volatile content, with a high carbon content of 98.2%. The conversion process to expandable Graphite was successful, achieving an expansion rate of 325 ml/g, indicating high-quality material. The carbon content remained high at 98.5% post-expansion, and the onset temperature for expansion was around 200°C, consistent with the sulfuric acid/potassium permanganate method. Overall, the graphite sample shows excellent potential for expandable graphite production.
ProGraphite’s report summary states "This is an excellent result. In summary, it can be said that the material provided be easily and without problems converted into expanded Graphite. The expansion rate achieved (as the most important quality parameter) is at a high level, the Graphite seems to be very suitable to be used as precursor material for the production of expandable Graphite." ProGraphite recommends as a next step testing Volt's +50 mesh graphite as it believes that an additional 20% expansion can be achieved.
President and CEO of Green Battery, Tom Yingling, states, "These impressive results underscore the exceptional quality of our Berkwood graphite, positioning us strongly in the market for expandable graphite production. The potential for even higher expansion rates with further testing is particularly exciting and speaks to the superior quality and versatility of our Graphite. We are enthusiastic about the future and look forward to leveraging these advancements to create significant value for our shareholders and contribute to the growing demand for sustainable, high-performance graphite materials."
