USA Rare Earth achieved a significant milestone in its Texas Round Top Mine Project by successfully producing a sample of dysprosium oxide (Dy₂O₃) with a purity of 99.1 wt. percent.
The dysprosium oxide sample was produced using ore from the Texas Round Top deposit and USA Rare Earth’s proprietary rare earth extraction and purification technology, developed at the company’s Wheat Ridge, Colorado research facility. This breakthrough, verified by a third-party ISO 17025 certified lab, marks a crucial step as the company demonstrates its ability to extract and process high-purity rare earth oxides from its Texas Round Top deposit.
“Our engineering team in Colorado, led by Ben Kronholm, a leading mineral process technologist, made significant strides this past year in unlocking the deposit at Texas Round Top,” said Joshua Ballard, CEO.
“In addition to dysprosium oxide, our team has now produced a variety of rare earth elements, including terbium and the light rare earth element neodymium, among others. We’re excited about the progress we’ve made in bringing this processing capability back home to the United States while simultaneously unlocking the tremendous potential value we hold at Texas Round Top,” added Ballard.
The production of dysprosium oxide is particularly significant due to its critical role in advanced technologies that rely on the unique properties of heavy rare earth elements. Dysprosium is a key component in technologies such as semiconductors, as well as in many NdFeB rare earth magnets by enhancing their performance at high temperatures, such as in EV motors. NdFeB magnets are the strongest type of permanent magnets commercially available, and are the kind USA Rare Earth will be producing at its plant in Stillwater, Oklahoma. NdFeB magnets are essential for high-efficiency electric vehicle motors, wind turbine generators, and advanced defense systems, including missile guidance and control systems, among other technologies.
The Texas Round Top project holds significant potential to become a major source of domestic heavy rare earth production, in addition to other critical elements like gallium, beryllium and lithium, which are essential for advanced electronics and renewable energy technologies.
USA Rare Earth is building a vertically integrated, domestic rare earth element magnet production supply chain. USARE is constructing a NdFeB magnet manufacturing facility in Stillwater, Oklahoma. USARE also controls mining rights to the Round Top heavy rare earth and critical minerals deposit in West Texas, which holds significant deposits of heavy rare earth minerals, such as dysprosium, terbium, gallium, and beryllium among other critical minerals. USARE’s magnets and rare earth minerals are required for a wide variety of products used in the defense, automotive, aviation, industrial, medical, and consumer electronics industries. Texas Mineral Resources is a minority holder in USARE’s Round Top operating subsidiary.
