RARE EARTH FEED GRADES INCREASED BY UP TO 148%
• Metallurgical beneficiation testwork shows North Stanmore clay samples are highly
amenable to upstream beneficiation, which has the potential to significantly reduce
downstream processing costs and capital costs per product tonne.
• Average TREYO head grade across 31 samples increased from 1308 ppm to 2192 ppm
through rejecting +20 µm coarse material.
• Size by assay analysis shows that up to 70% of rare earths are hosted in the fine -20
µm size fraction, in as low as 28% of the total mass.
• Beneficiation testwork on a composite of 31 samples from within the pending initial
JORC Mineral Resource Estimate area shows rejecting the +20 µm coarse fraction
results in an average REE upgrade of 68%, with corresponding REE recovery of 58%
and mass rejection of 66%.
• Stage 2 metallurgical testwork program is well underway which includes flow sheet
design to produce a mixed rare earth carbonate (MREC) as the end product.
