Metallurgical Tests
Metallurgical tests performed at ProGraphite and SGS Canada returned excellent results
Battery Minerals
10 tonnes of material remains available for future testing by potential offtakers (40 clients have already tested the material)
ProGraphite results summary:
Main elemental impurities are Si, Al and Fe, typical for flake graphite. Impurities known to cause issues, such as S, Mn, or heavy
metals, at very low levels.
The combination of ash composition, crystallinity, oxidation resistance and purification behaviors makes this graphite very
valuable for traditional markets and new applications (e.g. CSPG)
SGS results summary:
Recovery of 84% for a blend of fresh rock and saprolite ore
Graphite particle size distribution 44% coarser than 80mesh
200t piloting was successfully completed in 2019
