Market Update

Further to the update on 29 June 2021 regarding the temporary suspension of trial mining operations from the Gakara Project in Burundi, Rainbow continues to engage with the Government of Burundi (the "Government") to allow operations and exports to re-start. During this Government mandated suspension, operating costs in Burundi have been minimised, with the vast majority of staff placed on suspension, such that the ongoing situation is not having a significant impact on the Company's cash flow forecasts.

Due to the visits of George Bennett, CEO, to Burundi in April, June, and July 2021, the Company understands that the primary concerns of the Government relate to the pricing of the rare earth mineral concentrate sold by Rainbow Mining Burundi SM, the local operating entity. Rainbow notes that this was addressed comprehensively in an independent report, dated 26 July 2019, that was commissioned by the World Bank at the request of the Government and compiled by SRK Consulting. This report, accepted by the Government in 2020, concluded that:

· The price paid by ThyssenKrupp, the multinational industrial group, for the Gakara rare earth mineral concentrate, which is established on the basis of internationally recognised pricing, is commercial and forms a reliable foundation for the computation of royalties payable to the Government.

· The export grades of each shipment are independently verified as accurate by two internationally recognised laboratories (ALS Laboratories in Canada and Baotou Research Institute of Rare Earths in China) and have been correctly reported to the Government for each shipment from Gakara to date.

· That Rainbow is a "model company for new market entrants".

Rainbow notes that the ongoing suspension contravenes Burundi law and has been imposed without due and proper process. For example, the Government has never provided credible, data-based alternative prices for the concentrate exported or any alternative credible third-party analysis of grades from the samples they hold for each batch exported to date.

The Company has asked the Government to lift the suspension as soon as possible to allow trial mining to resume, local staff to return to work and exports to restart thereby generating significant employment, revenue, royalties and taxes for Burundi.

George Bennett, CEO, said: "Whilst the situation facing Rainbow in Burundi is disappointing, it has allowed our team to focus on the substantially larger opportunity presented for near term development of Phalaborwa, which we see as the immediate catalyst of Rainbow's business model and the asset that will enable the Company to become a significant producer of rare earths to drive the green revolution. With the opportunity to fast track the project's development, I expect Phalaborwa to be a sizable, commercial scale producer of separated rare earth oxides, substantially surpassing the trial mining activities at Gakara.

Rainbow remains committed to the positive contributions we are able to make as a Company within our countries of operation and communities through the payment of taxes and royalties, the provision of employment, local investment and the support of local supply chains."

Notes to Editors:

Rainbow's strategy is to become a globally-significant producer of rare earth metals. NdPr 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 NdPr into deficit.

The Phalaborwa Rare Earths Project, located in South Africa, comprises an Inferred Mineral Resource Estimate of 38.3Mt at 0.43% TREO contained within gypsum tailings stacked in unconsolidated dumps derived from historic phosphate hard rock mining. High value NdPr 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, which produces one of the highest-grade concentrates in the world (typically 54% total rare earths oxides ("TREO")) through ongoing trial mining operations, is currently the only African producer of rare earths. The Gakara basket is weighted heavily towards NdPr, which account for over approximately 19.5% of the contained TREO and 85% of the value of the concentrate.
