Brazilian Rare Earths Lifts Monte Alto Indicated Resource by 41% to 3.5Mt at 10.7% TREO

Highlights:

• Indicated ultra-high-grade tonnes rose 41% to 3.5 million tonnes at 10.7% total rare earth oxide (TREO).

• Combined Indicated and Inferred material grew 29% to 4.4 million tonnes at 9.9% TREO, with Indicated resources holding 87% of contained TREO.

• A 5,000-metre step-out drilling programme is under way, while the concentrate sales feasibility study is targeted for the end of 2026.

Brazilian Rare Earths Limited (ASX: BRE) has delivered a sizeable upgrade to the Mineral Resource Estimate for its Monte Alto deposit in Bahia, Brazil, expanding the ultra-high-grade Indicated category and lifting confidence ahead of a planned concentrate sales study. At the time of writing, BRE shares were quoted at AU$1.805, up AU$0.109 or 6.489%.

Southern Extension Drives Growth

The estimate, prepared by ERM with an effective date of 13 October 2026, adds 8,100 metres of drilling across 33 holes, taking the database to 43,184 metres from 255 diamond holes. Indicated tonnes at Monte Alto South climbed by roughly 200% to 1.9 million tonnes, backed by thick, stacked mineralised horizons found beyond the earlier resource boundary.

The resource now stretches about 1,200 metres along strike and 300 metres across, starting at surface and reaching a modelled depth of 200 metres. It is reported above a 1% TREO cut-off inside an optimised pit shell.

Heavy Rare Earths and Co-Products

The company says the deposit contains about 3.1 million kilograms of dysprosium oxide and 572,000 kilograms of terbium oxide, alongside large volumes of neodymium-praseodymium, gadolinium and yttrium. Niobium, scandium, tantalum and uranium add potential by-product revenue.

Pricing data cited in the release shows terbium near US$8,000 per kilogram and dysprosium near US$4,000, compared with about US$120 for neodymium-praseodymium, which explains the focus on heavy rare earth content.

Growth Still Open

Results received after the data cut-off include 12.3 metres at 16.5% TREO in hole MADD0246 and 6.3 metres at 16.8% TREO in MADD0238. The competent person does not expect these to materially change the current estimate. Drilling is also planned in the bridging zone between the central deposit and the northern extension, and regional exploration continues to the south.

Studies and Caveats

Inferred resources make up 20% of the tonnes and carry lower geological confidence. The earlier scoping study was based on a previous estimate and is described as preliminary, with an accuracy of about plus or minus 40%. The updated figures will flow into future studies.
