Terbium Becomes the New Frontier: How West Secures Rare Earth Independence Through Kazakhstan

The race for rare earth elements is heating up, and terbium—a critical heavy rare earth element essential for military-grade magnets and advanced defense systems—sits at the center of Western supply chain anxieties. REalloys Inc., currently merging with Blackboxstocks Inc. (NASDAQ: BLBX), just made a strategic move that signals a broader shift: securing terbium and dysprosium supplies directly from Kazakhstan’s AltynGroup, then processing them entirely in North America.

For decades, North America imported rare earths but did little beyond initial refining, exporting materials offshore for critical conversion to metals and alloys. That model left Western supply chains dangerously exposed. The new partnership flips the script entirely—bringing Kazakhstan’s mineral wealth into dedicated U.S. processing plants, keeping terbium-bearing materials locked in a domestic pipeline from ore to finished product.

REalloys and AltynGroup: Locking in Terbium Through Kazakhstan’s Vast Reserves

After six months of negotiations, REalloys and Kazakhstan’s AltynGroup have outlined a decade-long supply framework with a strategic investment component aimed at scaling U.S. processing capacity. The agreement targets AltynGroup’s Kokbulak project—a 127,000-square-kilometer concession in the Karaganda and Kostanay regions holding over 350 million tonnes of iron ore.

Here’s the clever part: Kokbulak isn’t being developed as a new rare earth mine from scratch. Instead, the project extracts terbium, dysprosium, and other valuable elements from iron ore tailings—the waste byproduct of conventional mining. This dual-use approach accelerates Western access to heavy rare earths without the lengthy development timelines of greenfield mining operations.

Leonard Sternheim, CEO of REalloys Inc., framed the partnership this way: “Kazakhstan possesses some of the world’s largest rare earth deposits, and its location between Russia and China makes strategic cooperation essential for the United States. This collaboration brings a leading Central Asian private enterprise into a framework that supports both economic and national security interests for the West.”

The investment capital flows back into REalloys’ only dedicated rare earth metallization facility in the U.S., which already serves critical government clients including the Defense Logistics Agency and Department of Energy. The strategy isn’t about one asset—it’s about connecting every missing link: securing feedstock in Kazakhstan, moving it to North American plants, and transforming oxides into finished metals and alloys domestically.

Building the Complete Terbium Pipeline: From Mine to Magnet

REalloys operates across the entire supply chain. Upstream, the company controls Hoidas Lake in Saskatchewan—a resource rich in both heavy elements (dysprosium, terbium, gadolinium, erbium) and light elements (neodymium, praseodymium)—processed in collaboration with the Saskatchewan Research Council.

Downstream, REalloys produces metals, alloys, and magnet materials in Euclid, Ohio. The Kokbulak feedstock flows directly into this pipeline, ensuring terbium never leaves the Western hemisphere during conversion into critical materials for defense applications and advanced manufacturing.

For U.S. defense procurement, the calculus is straightforward: weapons programs depend on terbium-bearing magnets for guidance systems, radar, and high-performance electronics. These magnets remain in service for decades. Without domestic terbium sourcing and processing, downstream operations face catastrophic risk if foreign alloy supplies are disrupted. REalloys’ strategy—securing feedstock, processing terbium domestically, and maintaining established government supply relationships—addresses the vulnerability that cannot be improvised under pressure.

Western Strategy in Motion: Who’s Securing Terbium and Heavy Rare Earths

MP Materials and the Fort Worth Terbium Play

MP Materials Corp. (NYSE: MP) operates Mountain Pass, one of the world’s richest rare earth mines, but the company’s pivot toward processing marks the real breakthrough. In 2025, MP launched neodymium-iron-boron magnet production at its Fort Worth, Texas facility—using terbium-containing alloys refined from its own separated oxides. This vertical integration shields customers from Chinese processing monopolies.

The Department of Defense has backed MP’s development of heavy rare earth separation capabilities, specifically targeting terbium and dysprosium. With initial magnet capacity around 1,000 tonnes per year and expansion plans underway, MP positions itself as the domestic supplier for critical defense and commercial applications where terbium performance is non-negotiable.

Energy Fuels and White Mesa’s Monazite Advantage

Energy Fuels Inc. (NYSE American: UUUU) operates the White Mesa Mill in Utah—the only U.S. facility licensed to process monazite sands, a mineral naturally rich in terbium alongside uranium. By late 2025, the company was processing commercial quantities of these sands, extracting both materials from feedstock previously considered waste.

Energy Fuels has already advanced separation circuits for neodymium and praseodymium oxides, reducing U.S. dependence on Chinese processing infrastructure. The company has acquired heavy mineral sand assets in the Southern Hemisphere (Toliara Project and Bahia Project) to ensure monazite feedstock continuity—a vertical integration strategy that secures terbium supply autonomously.

Lynas’ Texas Play: Heavy Rare Earth Separation Comes to America

Lynas Rare Earths Ltd. (OTC: LYSDY), the world’s largest rare earth producer outside China, is constructing a heavy rare earth separation plant in Seadrift, Texas, with Department of Defense backing. This facility will produce terbium and dysprosium—the exact elements driving Western defense resilience initiatives.

Lynas’ restructured processing addresses regulatory risks while boosting capacity. The Australian producer’s Kalgoorlie facility now processes Mt Weld concentrate domestically, isolating radioactive waste before export—a model that improves supply chain transparency and reduces geopolitical exposure.

USA Rare Earth: Magnets First, Terbium Supply Second

USA Rare Earth, Inc. (NASDAQ: USAR) focuses on downstream magnet manufacturing rather than mining. Its Stillwater, Oklahoma facility specializes in sintered neodymium magnets for EVs and defense applications—products that often incorporate terbium for high-temperature performance requirements.

To secure feedstock, USA Rare Earth is developing the Round Top project in Texas, which contains heavy rare earths including terbium, plus lithium and gallium. Pilot processing is underway with interim supply agreements supporting current plant operations.

Critical Metals and Greenland’s Heavy Rare Earth Treasure

Critical Metals Corp. (NASDAQ: CRML) is advancing Greenland’s Tanbreez Rare Earth Project—one of the world’s largest heavy rare earth deposits containing significant terbium and zirconium reserves. The unique ore composition offers processing advantages over conventional deposits, potentially reducing reliance on existing supply chains.

The company’s trans-Atlantic strategy mirrors the REalloys-AltynGroup model: securing non-Chinese sources for Western markets.

Vale’s Copper-Nickel Pivot

Vale S.A. (NYSE: VALE) is restructuring by separating base metals from iron ore operations, executing a $25-30 billion investment plan to boost copper output to 900,000 metric tons and nickel to 300,000 metric tons annually by 2030. While not directly terbium-focused, Vale’s supply to EV battery chains indirectly supports the broader shift toward critical minerals independence.

The Terbium Imperative: Why Timing Matters

Western governments recognize that terbium supply autonomy isn’t optional—it’s existential for defense superiority. Terbium’s role in high-temperature permanent magnets makes it irreplaceable for advanced weapons systems, satellite components, and next-generation radar.

The REalloys-AltynGroup partnership, combined with MP Materials’ magnet production, Lynas’ Texas separation plant, and Energy Fuels’ monazite processing, signals a coordinated Western strategy to disintermediate Chinese processing control. Within the next 3-5 years, terbium supply chains will look fundamentally different: diverse sourcing, North American processing, and direct government procurement integration.

For investors tracking critical minerals, terbium transitions from obscure element to mainstream portfolio consideration. Companies securing terbium feedstock, building processing capacity, or manufacturing terbium-dependent products are positioning themselves at the center of a supply chain revolution that transcends commodity trading—it’s now a matter of national security aligned directly with Western defense strategy.
