19 JUNE 2024 WEST ARUNTA PROJECT INITIAL METALLURGICAL TESTWORK RESULTS Highlights ▪ Excellent flotation results demonstrate a high-grade niobium concentrate with low impurities and industry comparable recovery rates can be produced from Luni oxide mineralisation using a conventional two stage flotation regime ▪ Initial flotation testwork was completed on sample material from a drillhole located in the northeast of Luni ▪ Open cycle float tests achieved a high-grade concentrate with excellent recovery: Open cycle concentrate (2 nd cleaner) 51% Nb2O5at 62% recovery Open cycle concentrate (4 th cleaner) 61% Nb2O5 at 52% recovery ▪ Subsequent locked cycle testing confirmed the flotation regime performance: Locked cycle concentrate (5 th cleaner) 58% Nb2O5 at 53% recovery ▪ Ongoing testwork is aiming to optimise the beneficiation stage including testing other process steps used at existing niobium operations, before moving to variability testing across Luni
