Notes to Editors:

Rainbow's strategy is to identify near-term, secondary rare earths production opportunities. Meeting escalating demand for critical minerals needed for global decarbonisation, we are focused on producing the magnet rare earth metals neodymium and praseodymium ("NdPr"), dysprosium and terbium. With our strong operating experience, proven project development experience, unique intellectual property and diversified portfolio, Rainbow will develop a responsible rare earths supply chain to drive the green energy transition.

The Phalaborwa Rare Earths Project, located in South Africa, comprises an Inferred Mineral Resource Estimate of 30.7Mt at 0.43% TREO contained within unconsolidated gypsum stacks derived from historic phosphate hard rock mining. High value NdPr oxide represents 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 in the stacks. The rare earths are contained in chemical form in the gypsum stacks, which allows high-value separated rare earth oxides to be produced in a single processing plant at site with lower operating costs than a typical rare earth mineral project.
