Desert Metals will load up a 20,000m drilling program in 2023 to capitalise on the major success of its rare earths exploration at the Innouendy project in WA and post a maiden JORC Resource.
An interim resource based on its 2022 drilling is likely after final assays returned from the labs, demonstrating the widespread nature of rare earth oxide intersections in saprolitic clays at Innouendy.
They confirm the high-grade, thick and continuous rare earths mineralization at Innouendy continues along a strike of at least 21km and across widths of 2.5km.
Significant total rare earth oxide intercepts reported by Desert Metals (ASX:DM1) from the final batch of assays include:
313 aircore holes have been completed at Innouendy, with drilling next year to both infill and further test the limits of the discovery, located in WA’s rich Murchison mining district.
The latest results include assays from the Cattle Yard prospect 3.5km south-west of Innouendy, as well as two new rare earth element zones 1.5km and 3.5km south west of Cattle Yard.
Of the drilling, completed across the 21km strike length of the Innouendy discovery, 78% of holes have contained TREO grades upwards of 300ppm and high value magnetic rare earth oxides make up around 23% of those significant intercepts.
Those are the most prized rare earth elements, expected to see a radical uptick in demand this decade and beyond from their use in the permanent magnets inside EVs and wind turbines.
Early metallurgical test work on samples from Innouendy has been positive, with recoveries from samples tested in weak acid digest that demonstrate REEs in the Innouendy mineralisation are leachable in acid.
More recent samples reported last week, demonstrating “exceptional leach recoveries” of magnetic rare earth oxide above 84% and critical rare earth oxide above 83% have given Desert Metals confidence as it moves into a new phase of met test work.
Work in 2023 will continue to determine the most cost-effective processing methodology for the extensive Innouendy mineralisation, with a scoping study expected in the second half of 2023.
DM1 says it has engaged an experienced metallurgist and study manager to manage the next phase of metallurgical test work and process flow sheet preparation.
