Brazilian Critical Minerals Limited Announced Massive Maiden Critiacal Mineral Resource (REE) Estimate >1 Billion Tonnes TREO - 2024

Rare Earth Deposits & Mining

Brazilian Critical Minerals Limited announced a maiden Mineral Resource Estimate (MRE) for the Ema and Ema East projects (collectively Ema), forming part of the Company´s wholly owned REE projects, Apuí, Amazon, Brazil at a cut-off of 500 ppm the Inferred Mineral Resource Estimate contains 1,017 Million tonnes @ 793 ppm TREO.

Highlights

• JORC 2012 compliant Inferred Mineral Resource Estimate (MRE) of 1.02 Billion tonnes @ 793 ppm TREO, including a higher-grade portion of 331 Million tonnes @ 977 ppm TREO;
• Ema as one of the largest tonnage fully ionic clay, rare-earth deposits in the world;
• Highly magnetic rare-earth oxides (REOs) (Nd, Pr, Dy, Tb) element proportion of 27 to 31% of basket (aka as a group) positioning, it as one of Brazil’s most enriched MREO deposits; 
• MRE developed from only 46% of the available area at Ema, with 107 km² available for further exploration;
• The mineralization is close to surface, amenable to low-cost open-pit mining methods and remains open at depth and to the east and west; and
• Drilling program is now being designed to convert MRE from Inferred to Indicated and Measured categories.

MRE when coupled with previously announced world-class metallurgical testwork recovery results of the magnetic rare-earth oxides (MREO), as listed below, confirm the following:

• 10 metres @ 76% Nd, 74% Pr, 47% Dy and 54% Tb from 10m (EMA-TR-101);
• 6 metres @ 66% Nd, 61% Pr, 56% Dy and 83% Tb from 10m (EML-TR-059);
• 13 metres @ 71% Nd, 62% Pr, 45% Dy and 52% Tb from 5m (TR-071);
• 5 metres @ 66% Nd, 66% Pr, 52% Dy and 55% Tb from 12m (TR-059);
• 10 metres @ 65% Nd, 61% Pr, 43% Dy and 50% Tb from 10m (TR-110);
• Ema is a fully ionic clay rare earth deposit – there is currently zero drilling into fresh rock;
• Is amenable to a low cost REE metal recovery process – low reagent usage, high impurity removal in final product; 
• Recoveries achieved using standard weak ammonium sulphate leaching solution, pH 4, at ambient temperatures over low-leach times of only 30 minutes duration; and
• Results demonstrate mineralization is suited to low-cost processing through conventional processing facilities commonly used in China.

Andrew Reid, Managing Director, commented:

“Today’s announcement is very important for the Company and our shareholders as it now sets us on a path towards development. This result places Ema as one of the largest ionic rare earths deposits in the world. The team has done a tremendous job in getting such a large MRE defined in less than 1 year, which now confirms the immense potential of the Ema project in Brazil.

Not only do we have a massive mineral resource of >1 billion tonnes but also significantly we have >300 million tonnes at grades close to 1,000 ppm which will assist in generating positive financial cash flow models.

Opportunities to increase both grade and tonnage remain high due to the extremely conservative global specific gravity (SG) of 1.34 which was applied to the estimated volumes. Additional deeper, less weathered samples from the higher-grade horizon is expected to result in significantly higher specific gravities.

With only 46% of the total area drilled, the team is confident of increasing not only tonnages, but believes the opportunities to also increase the grade are well founded and will be tested through the next round of drilling commencing over the coming months. BCM is now well on its way to establishing the Company as a global rare earths leader.”
