AR3 is trying to be a good minnow, and it's pathway towards processing appears different to other REE hopefuls, as per the nature of the deposits. Early days, and lots of risks; will rewards follow? More cash will be needed, and sentiment towards the sector is lower than a year or so ago. SP at 36c is well off highs, and not much above the IPO price.
Metallurgical test results indicate viable processing pathway for Koppamurra Rare Earths Project
Leach optimisation test work has resulted in excellent recoveries of the four key magnet rare earth elements while reducing acid consumption and impurity dissolution providing potential for both an environmentally sound and commercially attractive process pathway to economically produce a high-quality specification product.
Highlights
• Excellent results from leach optimisation test work undertaken by ANSTO on drill composite samples taken from the Koppamurra prospect
• Results demonstrate a 50% reduction in acid consumption while maintaining average recoveries of 65% and up to 77% for the four key magnet Rare Earth Elements (REE) being Neodymium, Praseodymium, Terbium and Dysprosium providing potential for both an environmentally sound and commercially attractive process pathway
• High recoveries of the valuable magnet rare earths (Nd, Pr, Tb & Dy) have increased confidence of consistent metallurgical response over spatially diverse locations within Project area. Diagnostic leach recoveries for 10 composite samples collected across the extent of the recently announced updated Mineral Resource, (81.4Mt at 785ppm Total Rare Earth Oxide (TREO)), show notable consistency of response and very high tenor of recovery
• Impressive leach response of a high-grade sample, 15,502 ppm TREO, provides additional confidence the proportion of accessible REE in high grade samples is consistent with the representative composites in the Mineral Resource.
• 850kg of material extracted from the Trial Pit completed at Koppamurra earlier this year currently being processed by ANSTO for rare earth recovery and product specification analysis
• This is a significant step-up in the scale of test work and will pave the way for testing a 500 tonne bulk sample and advanced flowsheet development
