Energy Fuels (NYSE American: UUUU) announced that terbium (Tb) oxide produced at its White Mesa Mill in Utah has passed all qualifications for use by one of the world’s largest Japan-based rare earth permanent magnet manufacturers, enabling commercial REPM production without further validation.

The company previously qualified its neodymium-praseodymium (NdPr) and dysprosium (Dy) oxides for magnet manufacture. Energy Fuels highlighted terbium’s high strategic value, citing a benchmark price of about $5.5 million per tonne, and stated that, upon closing pending ASM and Vacuumschmelze acquisitions, it expects to become a leading vertically integrated mine-to-magnet producer in the U.S. and Europe.

3 terms
terbium oxide technical
"today's announcement of terbium oxide qualification"
Terbium oxide is a rare-earth metal combined with oxygen to form a solid material used in small amounts inside high-tech products like lighting, display phosphors, certain magnets and catalysts. Think of it as a specialty ingredient or pigment: tiny quantities can be essential to a device’s performance. Investors watch it because its scarcity, supply chain risks and price swings can affect costs and margins for manufacturers and the value of mining and processing companies.
heavy rare earth oxides technical
"qualification of Energy Fuels' heavy rare earth oxides"
Heavy rare earth oxides are chemical compounds made from the heavier elements in the rare earth group (like dysprosium, terbium and others) combined with oxygen; think of them as concentrated metal powders used to give magnets, lasers and other high-tech components special properties. They matter to investors because they are critical, hard-to-replace inputs in clean energy, electronics and defense supply chains, so shortages, production costs or trade shifts can quickly affect the profits and valuations of companies that make or rely on them.
ndfeb permanent magnets technical
"high-strength NdFeB permanent magnets used in a variety"
NdFeB permanent magnets are very strong magnets made from neodymium, iron and boron that pack far more magnetic power into a small piece of metal than ordinary magnets. Investors care because they are critical components in electric motors, wind turbines and many electronics; their supply, cost and production sit at the center of manufacturing competitiveness and can directly affect profit margins, capital spending and demand forecasts much like a gasoline engine is to an auto maker.

With today's announcement of terbium oxide qualification, Energy Fuels is one step closer to commercially producing the full portfolio of "light" and "heavy" rare earth oxides for permanent magnets.

DENVER, Aug. 19, 2026 /PRNewswire/ -- Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) (ASX: EF2), a leading U.S. producer of rare earth elements (REE), uranium, and other critical materials, today announced that its terbium (Tb) oxide has successfully passed all qualifications for use by one of the world's largest manufacturers of rare earth permanent magnets outside China.

Energy Fuels Inc., a US-based uranium and rare earth elements producer.

The Japan-based manufacturer has informed Energy Fuels that the Tb oxide produced at its White Mesa Mill in Utah meets their specifications and is approved for use in commercial REPM production with no further qualification or validation required.

"This latest qualification of Energy Fuels' heavy rare earth oxides marks another significant milestone in establishing a secure, diversified supply chain for critical rare earth materials," said Ross Bhappu, President and CEO of Energy Fuels. "Successful qualification of our terbium oxide by one of the largest Japanese rare earth permanent magnet manufacturers represents one of the strongest endorsements of our product quality and industry leading rare earth processing capabilities to supply the heavy rare earth materials needed for automobiles, advanced electronics, robotics, aerospace, defense systems, and other advanced technologies."

Terbium is among the most valuable and strategically important rare earth elements, serving as a critical input that improves the heat resistance and performance of high-strength NdFeB permanent magnets used in a variety of advanced technologies. Reflecting its extreme scarcity and limited production in the West, terbium oxide currently commands a market price of approximately $5.5 million per tonne according Benchmark Mineral Intelligence (CIF Europe),

Energy Fuels previously announced the qualification of its neodymium-praseodymium (NdPr) and dysprosium (Dy) oxides for the manufacture of rare earth permanent magnets.

Upon closing of the pending acquisitions of Australian Strategic Materials (ASM) and Vacuumschmelze (VAC), Energy Fuels expects to become the leading vertically integrated "mine-to-rare earth permanent magnet" producer in the U.S. and Europe. The NdPr, Tb and Dy oxides produced by the Company at the White Mesa Mill will be key components of the Company's supply chain.
