New Rare Earths Venture to Target High-grade Assets in US and Brazil

Privately owned Rare Earths Americas (REA) has formed in a bid to explore and develop high-grade rare earths assets in the US and Brazil, looking to consolidate supply chains for various domestic sectors.

The company, which raised AU$25 million in a private funding round, said it combines experienced operators and investors with “deep expertise across global mining, energy and critical materials.”

Included in the company's portfolio is the Foothills discovery, located in Georgia, US.

The site contains grades of up to 41.3 percent total rare earth oxides, including heavy rare earths crucial for high-performance magnets. REA has highlighted its strong logistics, low-cost power and streamlined path to permitting.

In Brazil, the Alpha and Constellation projects hold more than 1 billion metric tons of high-grade ionic clay rare earths mineralization, including dysprosium and terbium, which are essential for permanent magnets.

The Homer project, also located in Brazil, targets multiple carbonatite clusters with the potential for niobium discoveries in a region known for leading niobium mines.

“The rare earths market is undergoing a generational shift as the West races to secure its rare earths future,” said CEO Donald Swartz in a Monday (August 18) press release.

REA’s timing aligns with broader US efforts to reduce reliance on China, which currently controls nearly 70 percent of global rare earths processing and accounts for most heavy rare earths production.

In April, Beijing restricted shipments of seven rare earths to the US and other countries, prompting concern among automakers and defense contractors dependent on these materials.

The US government recently proposed a pricing support mechanism for domestic rare earths ventures in order to increase production and mitigate China’s influence.

Discussions last month, led by former White House Trade Advisor Peter Navarro and National Security Council official David Copley, included rare earths producers and major tech firms reliant on these critical minerals.

China’s dominance stems from billions of dollars invested in mining and processing since 2000, often with minimal environmental or safety oversight, allowing the country to produce rare earths at lower cost than western competitors.

The US response to the Asian nation's rare earths stranglehold has included efforts to develop domestic mine supply and build out refinement, processing and production capacity. American companies have also sought to secure alternative sources in Africa and Latin America, but investment and technology barriers remain significant.

Mountain Pass in California, the country’s only large-scale rare earths mine, produces bastnaesite carbonate, but relies heavily on foreign processing. MP Materials (NYSE:MP), the mine’s operator, posted a net loss of US$65.4 million in 2024, highlighting the challenge of competing with China’s low-cost production model.

REA’s launch positions it as a potential strategic player in this evolving landscape.

According to the company, the Foothills project offers a “streamlined permitting pathway” in the US, while the Alpha and Constellation projects in Brazil provide access to large-scale, high-grade heavy rare earths.

“With grade and strategic geography on our side, we intend to advance our rare earths projects to support the long-term supply of critical materials essential to domestic innovation,” Swartz added.
