[Encounter Resources Discovers High-Grade Heavy Rare Earth Ore at Aileron Rare Earth Mine in Western Australia] Encounter Resources has discovered a high-grade heavy rare earth ore body during drilling at the Crean niobium-rare earth deposit in the West Arunta region of Australia. This discovery indicates that the Aileron project has the potential to rival any rare earth mine in Australia. Specifically, diamond drilling intersected the ore starting from 91 meters below the surface, with the ore body extending for 49 meters. Notably, the TREO grade of this ore body reached 1.5%, while the niobium (as Nb2O5) grade was as high as 2.5%. Within this, there was an exceptionally rich section 7 meters thick, where the TREO grade surged to 6.3% and the niobium grade jumped to 8.1%. It is worth mentioning that the drilling did not reach the end of the ore body by the time it concluded. Additionally, this rich section also exhibited impressive Pr-Nd (oxide) grades of 1.5% and dysprosium-terbium (oxide) grades of 0.085%.
