Notes to Editors:

Rainbow's strategy is to become a globally-significant producer of rare earth metals. Nd/Pr are vital components of the strongest permanent magnets used for the motors and turbines driving the green technology revolution. Analysts are predicting demand for magnet rare earth oxides will grow substantially over the coming years, driven by increasing adoption of green technology, pushing the overall market for Nd/Pr into deficit.

The Phalaborwa Rare Earths Project, located in South Africa, comprises an Inferred Mineral Resource Estimate of 38.3Mt at 0.43% total rare earths oxides ("TREO") contained within gypsum tailings stacked in unconsolidated dumps derived from historic phosphate hard rock mining. High value Nd/Pr oxide represent 29.1% of the total contained rare earth oxides, with economic Dysprosium and Terbium oxide credits enhancing the overall value of the rare earth basket contained in the stacks. The rare earths are contained in chemical form in the gypsum dumps, which is expected to deliver a higher-value rare earth carbonate, with lower operating costs than a typical rare earth mineral project.

The Company's Gakara Project in Burundi has produced one of the highest-grade concentrates in the world (typically 54% TREO) through trial mining operations. The Gakara basket is weighted heavily towards Nd/Pr, which account for over approximately 19.5% of the contained TREO and 85% of the value of the concentrate.
