How is the US Government Supporting Rare Earth Development in Brazil?
The United States government is strategically investing in rare earth element (REE) projects in Brazil through the US International Development Finance Corporation (DFC). This funding represents a significant step in diversifying global rare earth reserves distribution beyond China's dominance and establishing secure sources for these critical minerals essential to modern technology and defense applications.
DFC's Initial $5 Million Commitment to Aclara Resources
The DFC has committed up to $5 million in development funding for Aclara Resources' Carina heavy rare earths project in Brazil. This initial investment primarily supports the ongoing feasibility study, which began in July 2025 and is expected to conclude by the end of Q1 2026.
This funding arrangement includes a potential conversion mechanism, allowing the DFC to convert its investment into equity if Aclara completes either:
- A single financing event exceeding $50 million, or
- Multiple financing events totaling at least $75 million within a 12-month period
Additionally, the DFC maintains a preferential option to provide or arrange further project financing once the feasibility study is complete.
According to Aclara CEO Ramón Barúa, this initial investment validates their strategy and represents an important first step toward a larger commitment from the DFC once the feasibility study is completed. Having such a strong partner helps de-risk the development of their Brazil project while providing additional confidence to potential offtakers currently evaluating Aclara as a long-term supplier of heavy rare earths.
