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
- Exploration upside: Significant upside bauxite potential with an Exploration Target, supported by 56,919 metres of historical Rio Tinto drilling, providing a pipeline for further resource upside
- Strategic options: BRE advancing strategic options for Amargosa to unlock shareholder value - joint ventures, de-merger/spin-out or IPO - to focus on its world-class Rocha da Rocha high-grade rare earth province
- Next steps: Scoping Study by end-2025, bauxite upgrade test-work to assess upside in product grades, and resource drilling growth upside and optimisation
BRE Managing Director and CEO, Bernardo da Veiga, said:
“Amargosa’s maiden mineral resource estimate defines a large-scale, high-quality bauxite province with premium alumina grades and low reactive silica - a key advantage as global alumina refineries prioritise higher-quality bauxite specifications from reliable, stable jurisdictions.
With direct highway access to bulk-export logistics in a Tier-1 jurisdiction, we see a clear path to an early, capital-efficient direct-ship bauxite operation with the potential to scale to higher production via a large-scale processed bauxite opportunity. A near-term Scoping Study will map these exceptional development pathways and support long-term value creation options for Amargosa.”
