Name of the Project
Phalaborwa Rare Earths Project.

Location
Limpopo, South Africa.

Project Owner/s
Rainbow Rare Earths signed an agreement with phosphate mining company Bosveld Phosphates in June 2023 to ensure it obtains 100% ownership of the Phalaborwa project. 

This updates the original project co-development agreement, which envisaged Rainbow’s earning a 70% interest in Phalaborwa further to the completion of a prefeasibility study. 

Rainbow has also been granted a call option to acquire the remaining 15% of the JV owned by Bosveld, in return for $7-million of equity in the company, at any time from October 31, 2023, to December 31, 2023.

Upon completion of a definitive feasibility study (DFS), the unincorporated JV will be transferred into an incorporated JV company and, at Rainbow’s election, Bosveld will transfer all assets required for the project into that company. 

Project Description
A preliminary economic assessment (PEA) has confirmed Phalaborwa's significant potential as a low capital intensity, high-margin, near-term rare earth development project. The project has a total Joint Ore Reserves Committee-compliant mineral resource estimate of 30.4-million tonnes at 0.44% total rare-earth oxides contained within two phosphogypsum stacks derived from historic phosphate hard-rock mining.

Rainbow Rare Earths will extract the rare-earth elements using a proprietary continuous ion-exchange and continuous ion-chromatography plant process, developed in conjunction with K-Technologies, in the US.

The PEA, published in October 2022, is based on processing 2.2-million tonnes a year of phosphogypsum over a 14.2-year project life to deliver 26 208 t of separated magnet rare-earth oxides (REOs). The project will produce all four of the key rare-earth elements used to create permanent magnets (neodymium, praseodymium, dysprosium and terbium), and is believed to have the highest basket price of any rare earths project – $175.89/kg – outside of China, while the average processing cost is estimated at $33.86/kg.

Potential Job Creation
The project will create numerous employment opportunities during construction, and an estimated 300 direct job opportunities, excluding contractors, suppliers, vendors and consultants. Priority will be given to the people in the Ba-Phalaborwa area who have the requisite skills and experience. Rainbow will give preference to local contractors and where contractors are imported from other areas, Rainbow will encourage the employment of local labour.

Net Present Value/Internal Rate of Return
The project has an after-tax net present value, at a 10% discount rate, of $627-million and an internal rate of return of 40%, with a payback of less than two years.

Capital Expenditure
$295.5-million.

Planned Start/End Date
Production is expected to start in 2026.

Latest Developments
Rainbow Rare Earths has achieved several milestones in the financial year ended June 30, 2023. It is set to focus on the production of separated REOs at a back-end pilot plant, in the US, and complete a definitive feasibility study (DFS) by the end of 2024.

Rainbow has already achieved a major milestone with the production of first mixed rare-earth sulphates from phosphogypsum material at a front-end pilot plant in Johannesburg.

The material stems from the company’s Phalaborwa project, in South Africa, which is undergoing environmental permitting and a DFS.

The front-end material will be used as feedstock for the back-end pilot plant, for further processing to produce separated REOs.

The company will also prioritise gaining a better understanding of the mineralogy of the Uberaba stack, which will inform the future work programme around resource delineation and the development of a flowsheet.

Rainbow intends to continue evaluating the optimal technique for the extraction of rare-earth elements from sedimentary-sourced phosphogypsum.

Key Contracts, Suppliers and Consultants
ANSTO Minerals (plant processing testwork); K-Technologies Inc (REO separation technology and partner in developing plant processing flowsheet; managing the back-end of the pilot plant at its facility, in the US); Mintek (managing plant front-end in South Africa); and METC Engineering (production of the PEA and engineering work for the DFS).
