Agreement With Rio Tinto Unlocks Potential Development of BRE's Advanced High-Grade Bauxite-Gallium Project
Brazilian Rare Earths (BRELY) has restructured its agreement with Rio Tinto Brazil regarding the Amargosa Bauxite Project, replacing a US$40m milestone payment with a US$1.00/wet tonne royalty on future bauxite sales.
The project, acquired from Rio Tinto in 2023, features extensive exploration data including 56,919 metres of drilling across 4,257 holes. Recent drilling has revealed high-grade bauxite zones with intercepts of 27.5 metres at 51.3% total available alumina content.
A significant discovery has been made with the re-assaying of 1,275 bauxite samples, revealing exceptional gallium grades up to 190 ppm Ga2O3, with a mean grade of 75 ppm Ga2O3, positioning Amargosa among the highest-grade undeveloped gallium prospects globally.
The company has engaged RPM Global to accelerate development activities for a JORC-compliant Mineral Resource Estimate and Scoping Study, aiming to capitalize on rising demand and supply chain constraints in global bauxite and gallium markets.
Brazilian Rare Earths (BRELY) ha ristrutturato il suo accordo con Rio Tinto Brasile riguardo al Progetto Bauxite Amargosa, sostituendo un pagamento di milestone di 40 milioni di dollari con una royalty di 1,00 dollari per tonnellata umida sulle future vendite di bauxite.
Il progetto, acquisito da Rio Tinto nel 2023, presenta ampie dati di esplorazione che includono 56.919 metri di perforazione su 4.257 fori. Le recenti perforazioni hanno rivelato zone di bauxite di alta qualità con intercettazioni di 27,5 metri con il 51,3% di allumina totale disponibile.
È stata fatta una scoperta significativa con la ri-analisi di 1.275 campioni di bauxite, rivelando gradi eccezionali di gallio fino a 190 ppm Ga2O3, con un grado medio di 75 ppm Ga2O3, posizionando Amargosa tra i progetti di gallio non sviluppati di più alta qualità a livello globale.
L'azienda ha coinvolto RPM Global per accelerare le attività di sviluppo per una Stima delle Risorse Minerali conforme al JORC e uno Studio di Fattibilità, mirato a capitalizzare sulla crescente domanda e sulle restrizioni della catena di approvvigionamento nei mercati globali di bauxite e gallio.

브라질 희토류(BRELY)는 아마르고사 보크사이트 프로젝트와 관련하여 리오 틴토 브라질과의 계약을 재구성하여 4천만 달러의 이정표 지불을 향후 보크사이트 판매에 대한 톤당 1.00달러의 로열티로 대체했습니다.
2023년 리오 틴토로부터 인수한 이 프로젝트는 4,257개의 구멍에 걸쳐 56,919미터의 시추를 포함한 방대한 탐사 데이터를 특징으로 합니다. 최근 시추에서는 51.3%의 총 가용 알루미나 함량을 가진 27.5미터의 고품질 보크사이트 구역이 발견되었습니다.
1,275개의 보크사이트 샘플의 재분석을 통해 최대 190 ppm Ga2O3의 뛰어난 갈륨 함량이 밝혀졌으며, 평균 함량은 75 ppm Ga2O3로, 아마르고사를 전 세계에서 가장 높은 등급의 미개발 갈륨 전망 중 하나로 자리매김하게 했습니다.
회사는 RPM Global을 참여시켜 JORC 준수 광물 자원 추정 및 범위 연구를 위한 개발 활동을 가속화하고, 전 세계 보크사이트 및 갈륨 시장의 증가하는 수요와 공급망 제약을 활용할 계획입니다.
Brazilian Rare Earths (BRELY) a restructuré son accord avec Rio Tinto Brésil concernant le Projet de Bauxite Amargosa, remplaçant un paiement d'étape de 40 millions de dollars par une redevance de 1,00 dollar par tonne humide sur les ventes futures de bauxite.
Le projet, acquis de Rio Tinto en 2023, dispose de vastes données d'exploration comprenant 56 919 mètres de forage à travers 4 257 trous. Les forages récents ont révélé des zones de bauxite de haute qualité avec des interceptions de 27,5 mètres à 51,3 % d'alumine totale disponible.
Une découverte significative a été faite grâce à la réanalyse de 1 275 échantillons de bauxite, révélant des teneurs exceptionnelles en gallium allant jusqu'à 190 ppm Ga2O3, avec une teneur moyenne de 75 ppm Ga2O3, plaçant Amargosa parmi les projets de gallium non développés de la plus haute qualité au monde.
L'entreprise a engagé RPM Global pour accélérer les activités de développement pour une Estimation des Ressources Minérales conforme au JORC et une Étude de Faisabilité, visant à tirer parti de la demande croissante et des contraintes de la chaîne d'approvisionnement sur les marchés mondiaux de la bauxite et du gallium.
Brazilian Rare Earths (BRELY) hat seine Vereinbarung mit Rio Tinto Brasilien bezüglich des Amargosa-Bauxitprojekts umstrukturiert, indem eine Meilensteinzahlung von 40 Millionen US-Dollar durch eine Lizenzgebühr von 1,00 US-Dollar pro nasser Tonne auf zukünftige Bauxitverkäufe ersetzt wurde.
Das Projekt, das 2023 von Rio Tinto erworben wurde, verfügt über umfangreiche Explorationsdaten, darunter 56.919 Meter Bohrungen in 4.257 Löchern. Jüngste Bohrungen haben hochgradige Bauxitzonen mit Interzepten von 27,5 Metern bei 51,3% insgesamt verfügbaren Alumina ergeben.
Eine bedeutende Entdeckung wurde durch die Wiederanalyse von 1.275 Bauxitproben gemacht, die außergewöhnliche Galliumgehalte von bis zu 190 ppm Ga2O3 ergaben, mit einem Durchschnittsgehalt von 75 ppm Ga2O3, wodurch Amargosa zu den hochgradigsten unentwickelten Galliumvorkommen weltweit zählt.
Das Unternehmen hat RPM Global beauftragt, die Entwicklungsaktivitäten für eine JORC-konforme Mineralressourcenschätzung und Machbarkeitsstudie zu beschleunigen, um von der steigenden Nachfrage und den Lieferkettenengpässen auf den globalen Bauxit- und Galliummärkten zu profitieren.

- High-grade gallium discovery with exceptional grades up to 190 ppm Ga2O3
- Extensive existing exploration data (56,919m drilling) reduces development time and costs
- High-grade bauxite content confirmed with 51.3% alumina intercepts
- Strategic positioning to supply growing bauxite and gallium markets
- Ongoing royalty payments may impact long-term profitability
- Additional capital required for JORC compliance and development studies
- Project still in early development stage without defined resources
SYDNEY, April 14, 2025 (GLOBE NEWSWIRE) -- Brazilian Rare Earths Limited (ASX: BRE / OTCQX: BRELY) (BRE) is pleased to announce that it has entered into a binding agreement with Rio de Contas Desenvolvimentos Minerais Ltda. (Rio Tinto Brazil) to amend the Amargosa Tenement Acquisition Agreement.
Amargosa Bauxite Project
- Amargosa is an advanced stage, large-scale bauxite project acquired from Rio Tinto in 2023, adjacent to select BRE rare earth tenements in Bahia, Brazil
- The large-scale bauxite project benefits from over 10 years of exploration by Rio Tinto, including 56,919 metres of drilling across 4,257 holes and detailed geological data sets
- Exploration to date has confirmed thick, high-grade bauxite zones from surface, including intercepts such as 27.5 metres at
51.3% total available alumina content with low levels of reactive silica and iron - BRE and Rio Tinto have signed a binding agreement to replace the existing US
$40m bauxite milestone payment at the Amargosa Bauxite Project with a fixed US$1.00 /wet tonne royalty on future bauxite sales
High-Grade Gallium Discovery
- BRE has re-assayed 1,275 Rio Tinto bauxite samples collected at the Pelé Bauxite Project
- New, high-grade gallium discovery confirmed with exceptional grades of up to 190 ppm Ga2O3, with a mean grade of 75 ppm Ga2O3
- These assay results place Amargosa among the highest-grade undeveloped gallium prospects globally, with the potential to deliver strategic gallium supply amid ongoing geopolitical disruptions to global gallium markets
Amargosa Bauxite-Gallium Project Development
- Given the potential scale and quality of the bauxite-gallium prospects, BRE will rapidly advance the Amargosa bauxite-gallium project, and has engaged RPM Global to accelerate development activities for a JORC-compliant Mineral Resource Estimate and Scoping Study
- Amargosa is strategically positioned to supply seaborne bauxite and gallium markets facing rising demand and geopolitical risks
Brazilian Rare Earths’ CEO and MD, Bernardo da Veiga, commented:
“Global bauxite and gallium markets are underpinned by compelling structural trends - strong demand, constrained supply, and rising geopolitical risks to supply chains.
We are focussed on advancing our world-class, high-grade rare earth province - and this successful restructuring of the Rio Tinto agreement enhances our strategic flexibility to create long-term value for shareholders.”
