Australian Bauxite Limited report results from leach testing of its rare earth element mineralisation at the DL130 bauxite-REE project in northern Tasmania. ABx discovered mineralisation enriched in the super-magnetic rare earth elements Neodymium, Praseodymium, Terbium and Dysprosium which are strategically important, high priced metals needed for electric vehicles, wind turbines, smart phones and military electronics. A 400% enrichment of sulphur (S) in the precipitate was unexpected and may indicate that soluble REE may be leached strongly by dilute sulphate solutions. A test using dilute solution of ammonium sulphate and water is in progress to test this concept.
