Update on Rare Earth assays and Metallurgy testing

Australian Critical Minerals Limited (ASX: $ACM) has provided an update on the Rare Earth assays from the Beverley Project, Metallurgy testing of RC drill samples, and Composites from the Rankin Dome Projects in Western Australia. The company is earning a 51% interest from Kula Gold Limited (ASX: $KGD). Preliminary leach tests conducted by Australia's Nuclear Science and Technology Organisation (ANSTO) on selected Rankin Dome RC drill samples revealed that Magnetic Rare Earth Oxides (MREO) comprise up to 23% of Total Rare Earth Oxides (TREO). Additionally, the Beverley Project returned up to 2119 ppm TREO from moderately weathered granitic drill samples.

Executive Commentary on Rare Earth Assays and Metallurgy Testing

The low TREO recoveries achieved by the desorption tests indicate that only a minor component of desorbable rare earths occurs in the samples, with the majority occurring in some refractory form or forms. ACM intends to investigate whether rare earth mineralogy can vary with depth in the weathering profile or between areas within the extensive TREO anomaly outlined to date at Rankin Dome. There may also be scope to enhance rare earth recoveries using some method of beneficiation and concentration, such as magnetic separation, before applying more aggressive lower pH leach conditions. The Beverley Rare Earth results provide supporting criteria for testing the zones below the kaolin horizons for occurrences of rare earth oxides. In future kaolin drilling campaigns at Beverley, the company will attempt to drill beyond the kaolin zones to test the rare earth concentrations and provide a qualitative evaluation.

Summary of Rare Earth Assays and Metallurgy Testing

Australian Critical Minerals (ASX: $ACM) has completed rare earth assays at the Beverley Project and Rankin Dome, with preliminary leach tests revealing up to 23% Magnetic Rare Earth Oxides (MREO) at Rankin Dome. The company intends to investigate the variation of rare earth mineralogy with depth in the weathering profile and between areas within the extensive TREO anomaly outlined at Rankin Dome. Additionally, the Beverley Rare Earth results provide supporting criteria for testing the zones below the kaolin horizons for occurrences of rare earth oxides. In future kaolin drilling campaigns at Beverley, the company plans to drill beyond the kaolin zones to test the rare earth concentrations and provide a qualitative evaluation. Australian Critical Minerals aims to be pivotal in delivering the processed minerals needed for a clean energy future, focusing on battery metals, including rare earths and lithium, which are fundamental in the clean energy transition to net zero emissions.
