Notes to Editors:

Rainbow Rare Earths aims to be a forerunner in the establishment of an independent and ethical supply chain of the rare earth elements that are driving the green energy transition. It is doing this successfully via the identification and development of secondary rare earth deposits that can be brought into production quicker and at a lower cost than traditional hard rock mining projects, with a focus on the magnet rare earth elements neodymium and praseodymium ("NdPr"), dysprosium and terbium.

The Phalaborwa Rare Earths Project, located in South Africa, comprises a total Mineral Resource Estimate of 30.4 Mt at 0.44% TREO contained within unconsolidated gypsum stacks derived from historic phosphate hard rock mining. High value NdPr oxide represents 29.0% 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. Rainbow will use a proprietary separation technique developed by its partner K-Technologies, Inc. for the plant at Phalaborwa, which simplifies the process of producing separated rare earth oxides (versus traditional solvent extraction), leading to cost benefits, as well as being more environmentally friendly.

The Phalaborwa Preliminary Economic Assessment has confirmed strong base line economics for the project, which has a base case NPV₁₀ of US$627 million^[1], an average EBITDA operating margin of 75% and a payback period of < two years. Pilot plant operations will commence in 2023, with the project expected to reach commercial production in 2026, just five years after work began on the project by Rainbow.
