Energy Fuels Inc., operator of the only conventional uranium mill in the U.S., announced Dec. 19 that it met a major milestone: its dysprosium oxide passed standards set by a leading South Korean automaker.
The name of the automobile manufacturer was not disclosed.
With this accomplishment, Energy Fuels’ dysprosium oxide is qualified for use in permanent magnets at 99.9% purity. The industry benchmark is 99.5% purity, according to Yahoo Finance.
In August 2025, Energy Fuels signed a memorandum of understanding with Vulcan Elements to use these rare materials for magnet production in the United States.
Dysprosium is a heavy rare earth element used to improve durability and performance in permanent magnets, vital components in robotics, electric vehicles and defense systems such as missiles. High-quality dysprosium is rarely found outside China.
Energy Fuels operates White Mesa Mill in Blanding, Utah. The mill, near the Ute Mountain Ute Reservation, has operated since 1980 and processes uranium, rare earths, heavy mineral sands, vanadium and medical isotopes.
It is also on track to be one of the “highest-grade uranium deposits mined in U.S. history.”
“Production of dysprosium oxide that meets stringent magnet specifications is yet another key milestone in the Company's critical materials strategy,” CEO Mark S. Chalmers said in a news release.
He added that the milestone highlights Energy Fuels’ growing expertise in the rare earth sector, especially its ability to produce high-purity, separated heavy rare earth oxides from monazite at the White Mesa Mill in Utah. He noted the accomplishment is even more significant because the dysprosium oxide was verified by a respected third-party end user.
In its third-quarter 2025 earnings, Energy Fuels reported total revenues of $17.7 million, a 342.5% increase from $4 million in the same period of 2024. The growth was driven by uranium sales of 240,000 pounds at a price of $72.38 per pound, compared with 50,000 pounds sold in the same quarter in 2024.
Energy Fuels expects to sell 620,000 to 880,000 pounds of uranium in 2026.
Energy Fuels said its Pinyon Plain Mine in Arizona and La Sal Complex in Utah have mined more than 1.6 million pounds of uranium in 2025, exceeding previous guidance by about 11%. It expects to continue to mine about 2 million pounds of recoverable uranium at the sites through at least 2026.
The company's advancements come amid federal efforts to bolster domestic mineral production. In March 2025, President Donald Trump signed an executive order titled “Immediate Measures to Increase American Mineral Production,” which expanded the list of critical minerals.
The goal of the executive order was to prioritize domestic output of these minerals, thus reducing reliance on foreign imports.
Energy Fuels Inc. is based in Lakewood, Colorado. Common stock trades on the New York Stock Exchange under the symbol UUUU and on the Toronto Stock Exchange under the symbol EFR.
