2. High tech applications that require graphite grading =99.95% TGA typically rely on synthetic graphite where purity is paramount and crystallinity less so. Campoona provides natural graphite at grades to rival synthetic graphite whilst at the same time delivering highly crystalline graphite.
3. Such ultra-pure natural graphite concentrates are very rare and generally confined to narrow vein-style graphite deposits.
4. Campoona is unique in that it can deliver very high quality graphite from a low cost, high yielding extractive process.
5. Ultra-pure graphite concentrate grades are repeatable for the Upper Claystone and BOCO (base of complete oxidation) horizons of the deposit representing the uppermost 70m (approx) of the deposit commencing at the surface. Tests on more competent graphite lying below BOCO are awaiting processing.
6. Further improvements in recovered grades are likely as various upgrading techniques remain to be tested over the coming months.
7. Medium and Fine flake recovery studies are still in progress.
8. Further metallurgical results including the percentages and grades of flake graphite to
