Brazilian Critical Minerals reports magnet REEs and economic in-situ potential

Brazilian Critical Minerals reports strong grades at Ema rare earths project
Results include magnet rare earths and point to economic in-situ mining
Mineral resource update expected early next year

Special Report: Assays from Brazilian Critical Minerals’ second batch of auger holes have returned strong grades to include in a resource update at the Ema rare earth elements (REE) project in Brazil.

The project shares almost identical characteristics with the ionic REE deposits in southwest China, the world´s largest-known ionic clay region, where a large proportion of the world’s production of rare earths is mined and processed annually.

Brazilian Critical Minerals’ (ASX:BCM) 270-hole infill auger program has now returned results including:

10m at 1,103ppm Total Rare Earth Oxide (TREO) from 10m (EMA-TR-236), ending in 1,817ppm TREO;
9.7m at 1,081ppm TREO from 2m (EMA-TR-229), ending in 1,398ppm TREO;
10m at 1,086ppm TREO from 8m (EMA-TR-258), ending in 1,765ppm TREO;
9.6m at 1,149ppm TREO from 5m (EMA-TR-245), ending in 837ppm TREO; and
9.8m at 1,107ppm TREO from 3m (EMA-TR-238), ending in 771ppm TREO.

So far, the results show excellent grades and thicknesses with strongly elevated neodymium (Nd) and praseodymium (Pr) grades directly above the fresh bedrock contact supporting the proposed in-situ recovery (ISR) mining approach.

This enhancement not only indicates a promising resource but also suggests that further exploration in these areas could be highly beneficial towards developing a low-cost, economic operation.

Scoping study on the horizon

Drilling is expected to wrap up by the end of the month, and approximately 49% of the assays have been returned – with the results to be included in an interim updated resource estimate that will underpin the project’s scoping study due for release in Q1 2025.

Plus, the results to date will allow the company to commence production and plant feed scheduling for the scoping study, as well as enable the pre-planning and in-situ field trials as part of a feasibility study scheduled for 2025.

An updated resource estimate based on the newly acquired density and assay data has commenced, with Stage 1 to include all assays received to date to underpin the scoping study.

The Stage 2 resource estimate update will include all assays from the 270-hole program.
