RENASCOR RESOURCES 30 July 2021 ASX : RNU Significant Events Quarterly Activities Report for the period ended 30 June 2021 Advanced mineral processing trials were completed on the downstream component of Renascor's planned vertically integrated Siviour Graphite Mine and Battery Anode Material Manufacturing Operation ( " Siviour " ) in South Australia . ○ Renascor achieved results of 99.99 % total carbon ( " C " ) ( versus anode industry standard of 99.95 % C ) , the highest purity levels achieved by Renascor to date¹ . О О The high purity results were achieved with Renascor's eco - friendly purification technique , which avoids the use of hydrofluoric acid ( " HF " ) and instead uses an environmentally friendly and cost - effective method to purify Renascor's Siviour natural flake graphite for use in lithium - ion battery anodes . In the recent tests , Renascor used sulfuric acid as the primary leaching agent , replacing hydrochloric acid , which Renascor used in previous tests² . By using sulfuric acid , Renascor expects increased operating and environmental efficiencies . Independent locked cycle flotation tests achieved graphite recovery of 94.5 % , an increase compared to 91 % in the Siviour Definitive Feasibility Study ( " DFS " ) ³ . ○ The increase in recovery offers the potential for increased economic efficiencies in the production of Graphite Concentrates , which Renascor plans to use as feedstock to produce Purified Spherical Graphite ( " PSG " ) in the downstream operation . Independent large scale pilot trials produced bulk quantities of high purity Graphite Concentrates from ore samples from the Siviour deposit . ○ о O The on - going pilot trials have achieved graphite purities of up to 97.5 % TC with graphite recovery of 93.2 % by adjusting regrind times in the flotation circuit . The increase in purity offers the potential for increased economic efficiencies in the downstream production of PSG , as less reagents and energy would be required in the downstream purification stage to achieve lithium - ion battery grade purities of + 99.95 % TC . Graphite Concentrates produced from the pilot will be used for equipment selection and large - scale customer testing to support progression to binding offtake agreements . Renascor's cash position as of 30 June 2021 was approximately $ 17.3M .
