Rare Earths Americas Advances Brazilian Ionic Clay Project with…

Event summary

Rare Earths Americas (REA) has commenced an initial assessment (IA) at its Constellation Rare Earths Project in Brazil's Poços de Caldas district.
The project hosts an inferred mineral resource of 266.2 million tonnes grading 2,637 ppm TREO, with the IA expected to include an initial mine plan and preliminary project economics.
The IA is targeted for completion in mid-2027, with the mineral resource estimate effective as of October 31, 2025.
REA holds three rare earth projects in Brazil, including Constellation, Alpha, and Homer-A, positioning it among rare earth developers in the region.

The big picture

Rare Earths Americas' initiation of an initial assessment at the Constellation Project underscores the growing strategic focus on Brazilian ionic clay rare earths, a critical source of heavy rare earth elements essential for high-performance magnets. The Poços de Caldas district has emerged as a key area for rare earth development, attracting significant investment and interest from established players. REA's portfolio of projects in Brazil positions it to potentially support future Western rare earth supply chains, amid increasing geopolitical considerations around critical mineral supply.

What we're watching

Project Viability: Whether the initial assessment will demonstrate the economic viability of the Constellation Project, given the inferred mineral resource's scale and grade.
Competitive Dynamics: How REA's advancement of the Constellation Project positions it against competitors like Lynas Rare Earths and USA Rare Earth in the Brazilian ionic clay rare earths space.
Regulatory and Permitting Risks: The pace at which REA can navigate regulatory and permitting challenges in Brazil, which could impact the project's timeline and cost.
