The United States is accelerating efforts to secure domestic supplies of critical minerals and rare earth elements as geopolitical tensions and supply chain vulnerabilities highlight the country’s dependence on China. One of the most significant developments in this effort is the Round Top rare earth project in Texas, considered one of the richest known deposits of heavy rare earth elements and critical minerals.
USA Rare Earth CEO Barbara Smith recently discussed the company’s strategy to commercialize the Round Top project and build a complete mine-to-magnet supply chain within the United States. The initiative is expected to play an important role in strengthening America’s defense industry, semiconductor manufacturing, and advanced technology sectors.
The Round Top deposit in Texas has long been recognized for its enormous potential. It contains one of the richest known deposits of heavy rare earth elements in the world. Despite this, the deposit remained largely undeveloped for many years because no company had successfully unlocked the technology required to extract and separate the rare earth minerals efficiently.
According to Barbara Smith, technological progress has now made the project feasible. Scientists working in Wheat Ridge, Colorado have demonstrated the capability to separate rare earth elements from the deposit, paving the way for commercial development. The company has designed an accelerated mine plan that aims to move quickly through the stages that normally take many years. The goal is to establish the required infrastructure, prove the deposit’s feasibility, and bring the mine into operation by 2028.
The geology of the Round Top deposit is unique compared with traditional rare earth mines. The minerals exist in a fluoride-based formation, which requires a different extraction method. The mining process involves extracting the rock, crushing it, and placing it into heap leach pads. Liquids are then used to leach out the heavy rare earth elements, which are later separated using solvent extraction techniques. This process allows the company to isolate the valuable rare earth elements from other minerals present in the deposit.
If successful, Round Top could become one of the most productive sources of heavy rare earth elements globally. These materials are critical for manufacturing technologies such as semiconductor chips, electric vehicle motors, fighter jets, missile systems, and artificial intelligence hardware.
The project also has significant national security implications. The United States currently depends heavily on China for rare earth supply chains, including mining, refining, and magnet manufacturing. China dominates much of the global rare earth industry, creating strategic vulnerabilities for countries that rely on these materials for defense and high-tech industries.
Developing domestic production capacity is therefore seen as essential for reducing reliance on Chinese supply chains. The Round Top project is located on Texas state land, and the Texas Land Commissioner has supported its development due to its strategic importance. Lease revenues generated from the project will also contribute to funding the Texas public school system, creating additional economic benefits for the state.
USA Rare Earth is not only focused on mining the minerals but also on building a fully integrated rare earth supply chain in the United States. The company recently secured $1.5 billion in PIPE financing to expand operations across multiple stages of the rare earth value chain. The funding will support mining operations, metal production, alloy manufacturing, and magnet production.
The company already operates facilities capable of producing heavy rare earth metals and alloys used in magnet manufacturing. Expansion efforts are underway, including exploring opportunities to increase metal production in Stillwater, Oklahoma. At the same time, the company is developing magnet manufacturing facilities and has already begun commissioning the first production line.
This integrated approach aims to create a domestic supply chain that covers every stage of production, from mining rare earth minerals to manufacturing finished magnets used in advanced technologies.
The push for domestic rare earth production is also receiving strong support from the U.S. government. President Donald Trump has launched an initiative known as Project Vault, which aims to create domestic reserves of critical minerals and strengthen the security of U.S. supply chains.
Project Vault identifies approximately 60 critical minerals essential to the U.S. economy and national security, including 17 rare earth elements. These materials are crucial for industries ranging from semiconductors and electric vehicles to aerospace and defense manufacturing.
Government agencies such as the Department of Commerce and the Export-Import Bank are working with private companies to accelerate the development of these resources. The objective is to ensure that American manufacturers have reliable access to critical materials even during global supply disruptions.
USA Rare Earth expects its metals and magnets to play a role in Project Vault, helping establish a domestic reserve of critical minerals. The company is already producing rare earth metals and plans to expand magnet production in the near future.
Demand for rare earth magnets continues to rise rapidly as industries transition toward electrification and advanced technologies. Electric vehicle motors, wind turbines, fighter jets, and artificial intelligence hardware all rely on these high-performance magnets.
USA Rare Earth plans to prioritize supplying sectors considered strategically important for the United States, including the technology industry, aerospace and defense manufacturing, and companies involved in artificial intelligence development.
Barbara Smith also emphasized that the rare earth industry remains highly fragmented. To compete globally and scale production more efficiently, the company plans to pursue mergers and acquisitions that consolidate different parts of the supply chain.
By building a vertically integrated structure that includes mining, processing, metal production, magnet manufacturing, and final product delivery, the company aims to create a stronger and more reliable domestic rare earth ecosystem.
The race for critical minerals is intensifying worldwide as countries attempt to secure the resources necessary for technological leadership and national security. Rare earth elements are essential for the future of semiconductors, electric vehicles, renewable energy systems, artificial intelligence, and advanced defense technologies.
The development of projects such as Round Top represents a major step toward rebuilding America’s domestic industrial capacity and reducing reliance on foreign suppliers. If the project succeeds, it could position the United States as a major player in the global rare earth market and strengthen supply chains for the technologies that will shape the future economy.
