Amargosa Bauxite-Gallium Project Mineral Resource Estimate

Brazilian Rare Earths

Maiden Mineral Resource Estimate of 568 Mt, including 98 Mt Direct-Ship Bauxite; 27,098,000 kg contained Gallium

SYDNEY, Oct. 03, 2025 (GLOBE NEWSWIRE) -- Brazilian Rare Earths Limited (ASX: BRE / OTCQX: BRELY) ('BRE') is pleased to announce the release of a Maiden Mineral Resource Estimate at the Amargosa Bauxite-Gallium Project, defining a large-scale, high-quality bauxite province with premium alumina grades and significant contained gallium.

BAUXITE MINERAL RESOURCE ESTIMATE
568 Mt at 29.8% Total Available Alumina (TAA), including:
Direct-Ship Bauxite: 98 Mt at 41.9% TAA Processed Bauxite: 191 Mt at 40.8% TAA
Benchmark-grade bauxite: Direct-ship bauxite product specifications aligned to the Guinean benchmark for metallurgical bauxite - attractive to international refiners seeking high-quality supply from a reliable, stable jurisdiction Low RSI advantage: Low reactive silica index (RSI) lowers caustic consumption, improves alumina recovery, and is well-placed for tightening refinery feed specifications High-confidence geology: Nearly 90% of the direct-ship resource within the Indicated Mineral Resource category - higher geological confidence to support mine-planning and economic studies Processing uplift at scale: 470 Mt at 27.3% TAA, 6.2% RSI processed to 191 Mt product at 40.8% TAA, 2.7% RSI - potential capital-efficient pathway to export-grade bauxite

GALLIUM MINERAL RESOURCE ESTIMATE
568 Mt at 47.7 ppm: 27,098,000 kg contained Gallium
Strategic gallium opportunity: Resource hosts 27,098,000 kg of contained gallium - which positions Amargosa for emerging strategic supply chains essential for semiconductors, high-performance permanent magnets and defence applications

(Indicated + Inferred)	Processed 20+ Mesh Product
	Tonnes (m)	TAA (%)	RSI (%)	Ga (ppm)	Ga ('000 kg)
Beneficiable Bauxite	191	40.8%	2.7%	n.a.	n.a.
Total	191	40.8%	2.7%	n.a.	n.a.

Capital-Efficient, Direct-Ship Logistics and Scalability

Leading jurisdiction: Amargosa located in Bahia, Brazil - supported by a mature regulatory framework, expedited licensing and permitting (2-3 years), and strong governmental support for mineral development
Capital-efficient direct-ship opportunity: With 98 Mt of direct-ship bauxite (41.9% TAA; 2.5% RSI), Amargosa can initiate operations in the Northern District, leveraging established highways to the Enseada export port (~160km). Established highways extend these logistics to the Central District.
Enseada port MoU: Partnership signed with Port of Enseada that covers mine-to-port export logistics for Amargosa bauxite
High-quality infrastructure: Low-cost, renewable hydropower, with high-voltage transmission line access; multiple export-port infrastructure options; skilled local workforce; paved multi-lane federal and state highways; and planned FIOL rail integration to underpin rail-to-port expansion capacity
Scalable growth pathway: 191 Mt processed bauxite (40.8% TAA; 2.7% RSI) provides large-scale bauxite expansion opportunities using the future FIOL railway and Porto Sul export port
