• Large, independent JORC Code 2012 Mineral Resource (“Resource”) at the Yin REE Ironstone Complex (“Yin”) delivers a high confidence Resource with 87% in the Measured & Indicated catagorties.

• The Resource now totals 29.98Mt @ 1.04% TREO and has been delivered in only 18 months from discovery.

• The Resource only covers ~10% of the 43km long Yin strike.

• Importantly, an initial Measured Resource of 5.17Mt @ 1.34% TREO has been defined over just ~250m of strike where the thick, high-grade Resource occurs at surface. And the Indicated Resource has increased to 21.13Mt @ 1.02% TREO.

• This confirms the 100% owned Mangaroon project as a globally significant critical minerals complex with a combined, high confidence Resource at Yin and the Gifford Creek Carbonatite of 40.82Mt @ 1.03% TREO. This points to a long-life, strategically important, Tier 1 project in one of the world’s top investment jurisdiction, Western Australia (Investment Attractiveness Index - Fraser Institute, May 2023).
