ASX AnnouncementLicensing Agreement for Downstream Purification ProcessOptimised purification process delivers operating efficiencies in production of battery grade Purified Spherical GraphiteHighlightsRenascor has entered into a licensing agreement with leading German independent battery mineral consultancy group Dorfner ANZAPLAN to apply a hydrofluoric (HF) acid free purification process to produce battery grade Purified Spherical Graphite (PSG) at Renascor’s planned downstream manufacturing facility in South Australia.The eco-friendly purification process was developed from optimisation trials designed to create operating efficiencies by reducing the number of leaching steps required to achieve lithium-ion battery grade PSG. This follows initial locked-cycle purification tests on Renascor’s Siviour natural flake graphite completed in December 2021.New locked cycle purification trials completed in 2022, using the improved purification process, have confirmed that the process continues to meet or exceed lithium-ion battery anode purity specifications, with results of up to 99.99% carbon (C) (versus anode industry standard of 99.95% C).The new purification process offers reduced operational risk, by reducing the number of leaching stages, while also enhancing environmental efficiency by reducing water consumption.Renascor’s recently completed Battery Anode Material Study (BAM Study) has incorporated the new purification process into the engineering design for the proposed PSG facility, with the results of the BAM Study estimating a globally competitive PSG gross operating cost of US$1,782 per tonne over the first 10 years and US$1,846 per tonne over 40-year mine life.Commenting on the licensing agreement, Renascor Managing Director David Christensen stated:“We have been working with Dorfner ANZAPLAN for several years to optimise our purification process to improve the efficiency of our planned battery grade Purified Spherical Graphite manufacturing facility in South Australia.The optimisation trials conducted with Dorfner ANZAPLAN have resulted in the development of a process that we expect will result in both greater operational efficiency and positive ESG outcomes by reducing water consumption.This improved purification process has been incorporated in the engineering and design for our recently completed Battery Anode Material Study, with the results delivering a globally competitive estimated operating cost for producing PSG.We look forward to our continuing collaboration with Dorfner ANZAPLAN as we advance into construction and operation of an important new supply line for the lithium-ion battery industry.”
