Brazilian Rare Earths has expanded a high-grade rare earth discovery at its Sulista South project in Bahia, Brazil, with ongoing drilling testing mineralised zones that could eventually contribute feedstock to the company’s wider processing network and its supply-chain relationship with France.
Drilling has identified multiple mineralised seams across approximately 500 metres of strike, with true thicknesses reaching 18 metres and reported grades of up to 13.3% total rare earth oxides (TREO).
More than 10,000 metres of additional drilling is under way, and the company is targeting an updated mineral resource estimate before the end of 2026. The results represent an exploration milestone, but Sulista South remains outside Brazilian Rare Earths’ currently published development case and cannot yet be counted as a future source of production.
Drilling to establish resource scale and continuity
Further exploration will be required to determine the continuity, scale and recoverable grades of the mineralisation before Sulista South can be incorporated into a formal resource estimate and development plan. The company is examining whether the discovery could eventually be integrated into its planned Camaçari processing hub. If future studies establish the technical and commercial case for integration, Sulista could expand the volume of feedstock available to the company’s processing and offtake network.
No new financing for Sulista mine development was announced alongside the drilling results. The discovery therefore adds potential resource capacity rather than immediately available production or newly contracted supply.
French processing agreement provides a downstream connection
Brazilian Rare Earths already has a binding 10-year agreement with French processor Carester covering heavy rare earth feedstocks intended for the Caremag refinery at Lacq, France. Caremag has secured approximately €216 million in public funding from France and Japan, providing substantial institutional financial backing for the downstream processing facility.
Sulista South material has not been specifically allocated to the existing agreement. The discovery does not represent additional contracted European supply, and its potential contribution to the French-linked processing chain remains dependent on further exploration and development work. The distinction between the upstream and downstream stages remains important: the French refinery has secured public funding, while Sulista South is still at the exploration stage.
Magnet rare earths relevant to European supply security
Sulista South contains magnet rare earths used in electric vehicles, wind turbines, industrial motors and defence applications. The discovery could eventually broaden the range of feedstock available to Brazilian Rare Earths if the mineralisation is defined and developed. For Europe, potential access to additional heavy rare earth feedstock is particularly relevant for dysprosium and terbium, where Chinese supply-chain dominance is greater than for several other critical minerals.
No new European Union, French government, European Investment Bank or project financing was announced in connection with the latest drilling results. The €216 million Caremag funding package applies to the French refinery and does not finance development of the Sulista South deposit. The immediate development requirement is to establish a sufficiently defined and technically recoverable resource through continued drilling and subsequent studies before the deposit can be incorporated into a formal mining and processing plan.
