Cautionary Statement In relation to photographs of mine-spoil material, from Gulf Creek no representation as to the composition of the rocks is presented here. Laboratory assay results are required to determine the grade of mineralisation and the Company will update the market when check sampling and assay results are received and compiled. The Competent Person advises that the photographs contained in this Presentation are not necessarily representative of the geology exploited by historic mines at Gulf Creek and are not to be construed as being representative of potentially economic mineralisation. 2 IMPORTANT INFORMATION OD6 METALS | AUSTRALIAN CRITICAL MINERALS 3 A 100% Owned Australian Critical Minerals Project SPLINTER ROCK REE PROJECT HIGHLIGHTS • Strong Rare Earth Demand Fundamentals • 682Mt at 1,338 ppm TREO JORC Resource • ~75% Nd & Pr Overall Recovery • High-quality Mixed Rare Earth Carbonate (MREC) of ~56% TREO • High-quality Mixed Rare Earth Hydroxide (MREH) of ~59% TREO • Superior product quality with low levels of impurities (Al, Fe, P, Si) • Extremely low uranium and thorium content (<0.001% U + Th) • Optimised capital and operating cost drivers • Offtake Engagement – North America, Europe & Asia • Positive Study Outcomes - ANSTO and CPC • Accelerated Scale up Testing at ANSTO - 2.5t Metallurgical Core 1.
