• EcoGraf HFfree® process has a significant competitive advantage over competitors in process cost, quality and sustainability
• Total estimated cost to construct a 25,000tpa Purification Facility is US$95m, with a payback period of less than 4 years
• Purification cost reduced to US$478/t, a 34% reduction compared to hydrofluoric acid purification

EcoGraf Limited announced significant process design breakthroughs and optimisations for its EcoGraf HFfree® purification technology, which have delivered substantial process efficiencies and cost savings. Extensive testing and analysis has been undertaken to refine the EcoGraf HFfree® purification flowsheet, confirming the effectiveness of the process on a continuously operating basis and leading to a reduction in purification cost to US$478/t, based on an initial operating capacity of 25,000tpa. The total estimated cost to construct a Purification Facility with an initial capacity of 25,000tpa (including a 12% contingency) is US$95m, with economies of scale identified as production is expanded to meet the forecast growth in lithium battery demand. The initial 25,000tpa Purification Facility provides a pay-back period of less than 4 years, with the potential for future savings from the use of renewable energy supplies and processing refinements expected from commercial scale operations. These results show that the EcoGraf HFfree® process has a significant competitive advantage over competitors in process cost, quality and sustainability.

The Company is actively securing sales partnerships, financial support and also evaluating locations to develop its downstream projects in the key ex-China battery manufacturing markets.
