Brazilian Rare Earths Limited has released comprehensive, JORC-compliant data for its 74,824-hectare bauxite project in Bahia. The re-assay program validates historical exploration with robust sampling and secure, royalty-favored tenements, underscoring significant long‑term value potential in one of Brazil’s premier mining jurisdictions.
Brazilian Rare Earths Limited has released an in‐depth technical disclosure outlining the exploration, sampling, drilling, and quality assurance procedures applied at its extensive bauxite project in Bahia, Brazil. The report details that historical work by the previous operator involved nearly 57,000 metres of drilling through more than 4,200 holes using various techniques—primarily hand‐portable auger and aircore drilling—to obtain high‐frequency samples (typically every 0.5 metres) of the lateritic regolith hosting the bauxite mineralisation.
The disclosure explains that auger samples, collected with careful measures to minimize cross‐contamination, were complemented by near–100% recovery airflow data from aircore drilling. All samples were rigorously prepared—dried, crushed, and homogenized—and subsequently analyzed at qualified laboratories using techniques such as XRF and fire assay to determine key technical indicators. In particular, industry benchmarks such as Total Available Alumina Concentration (TAAC) and Reactive Silica (RSiO₂) were measured, with “crude quality” bauxite identified when intercepts exceed 35% TAAC and 40% Al₂O₃. Quality control protocols were robust: certified reference materials, blanks, and duplicate samples (approximately 5% of the total) were systematically integrated into the laboratory workflow to confirm precision and accuracy, with re-assay results showing an excellent correlation (R = 0.99) with historical data.
High-precision geodetic survey techniques were used to record drill collar positions, ensuring centimeter-scale accuracy and a well-documented spatial framework for future resource estimation. The historical drilling patterns, which range from 200- to 800-meter spacing in prospective areas (refined to 50- or 25-meter grids in high priority zones), have provided a solid basis for modeling the near-horizontal lateritic bauxite deposit. Composite techniques were adopted to report significant intercepts while accounting for variable intervals, such as short high-grade sections interspersed with lower grade or clay intervals.
Looking ahead, the company plans to undertake further JORC-compliant resource estimation and scoping studies that will assess the economic viability of the project, optimize metallurgical flowsheets, and refine the potential for upgrading the bauxite quality. The project spans extensive tenements that, together, cover tens of thousands of hectares with a secure tenement status that includes regulated royalty agreements and adherence to Brazil’s mining codes.
From a bullish perspective, the detailed technical approach and proven data integrity offer strong confidence in the deposit’s potential. The rigorous QA/QC measures, extensive drilling record, and high-grade “crude quality” intercepts establish a promising foundation for future development. On the other hand, a cautious view is warranted given that some key re-assays (such as TAAC and RSiO₂ verification) are still pending further scrutiny and that additional infill drilling may be necessary to fully define grade continuity—factors that could influence near-term valuations.
Overall, the announcement reflects a methodical and transparent exploration program that not only validates the historical data but also sets the stage for detailed resource estimation and scoping studies, providing a promising outlook for Brazilian Rare Earths Limited’s bauxite project.
