Brazilian Rare Earths Expands Monte Alto Deposit with Ultra-High-Grade Drilling
Event summary
- Diamond drilling at Monte Alto reveals ultra-high-grade extensions, including 25.6 m at 17.4% TREO and 8 m at 28.1% TREO.
- Deposit expanded south, east, and north, with new down-dip potential identified.
- All results post-cut-off, not included in current Mineral Resource Estimate or Scoping Study.
- 5,000 m drilling campaign underway to further expand mineralized envelope.
- Exceptional rare earth enrichment with NdPr grades up to 6.7% and high-grade co-products.
The big picture
Brazilian Rare Earths' successful drilling campaign at Monte Alto highlights the strategic importance of high-grade rare earth deposits amid growing demand for critical minerals. The expansion of the mineralized envelope and identification of new growth corridors position the company to potentially extend mine life or increase annual production, aligning with broader industry trends toward securing sustainable rare earth supply chains. The ultra-high-grade results underscore the deposit's exceptional enrichment, which could enhance project economics and attract investment.
