Rare Earths Americas Secures $16M for US-Brazil Mining

Rare Earths Americas (REA) has announced a successful $16 million seed round for its cross-continental approach to rare earth development. With a focus on reducing Western reliance on Chinese supply chains, the company is advancing projects in the United States and Brazil, targeting both high-grade and scalable sources of critical minerals.

Its flagship U.S. Foothills project is located on private land in Georgia—a detail that could significantly ease permitting timelines. Early exploration results have shown high grades, including 41.3% Total Rare Earth Oxides (TREO), with notable concentrations of heavy rare earths. These elements, including dysprosium and terbium, are vital for EVs, wind turbines, and defense systems, and often fetch higher prices due to limited global availability.

In Brazil, REA is developing the Alpha and Constellation projects, which it estimates contain over one billion tons of ionic clay rare earth mineralization. These types of deposits are generally considered more straightforward to process, offering a potential economic advantage. The company’s Homer Project introduces geological diversity, with its carbonatite formation presenting additional upside potential—particularly for niobium, a material where Brazil already holds a significant global share.

Infrastructure also plays in REA's favor. The Foothills site benefits from access to affordable energy and existing logistics networks, factors that have historically hampered rare earth production in many Western projects. Combined, the company’s asset base offers a mix of near-term feasibility and long-term growth, though all remain in early-stage development.

Navigating a Complex Market Landscape

REA’s strategy is aligned with a broader geopolitical and economic push to shore up domestic critical mineral capacity. With rare earth elements now considered essential to national security, clean energy, and next-gen technologies, supply chain diversification has moved from policy ambition to investment reality.

CEO Donald Swartz describes the current moment as a turning point in the rare earth sector, driven by accelerating demand and increasing pressure to localize key segments of the supply chain. Governments in North America and Europe are responding with subsidies, tax incentives, and legislative frameworks—like the U.S. Defense Production Act—to back non-Chinese sources of critical materials.

The challenges are well known, however. Rare earth extraction and processing are technically demanding, requiring specialized infrastructure and careful environmental management. While REA’s initial raise gives it momentum, the capital intensity of rare earth development means the path to production will likely require multiple funding rounds and strategic partnerships.

The company’s success will depend not only on its geology but also on its ability to advance permitting, build competitive processing capabilities, and secure long-term offtake or government support. With China still dominating the refining and magnet manufacturing supply chain, Western entrants like REA will need more than resource-rich ground—they’ll need execution that bridges political ambition and commercial viability.
