REalloys (NASDAQ: ALOY) signed a binding 15-year offtake agreement on May 20, 2026, securing 15% of Phase 1 production from Critical Metals Corp.'s Tanbreez heavy rare earth deposit in southern Greenland, one of the world's largest known sources of dysprosium and terbium outside Chinese jurisdiction. The deal directly targets the Pentagon's January 1, 2027 deadline banning Chinese-origin rare earth materials from U.S. defense procurement, and anchors REalloys' vertically integrated mine-to-magnet strategy centered on a heavy rare earth metallization facility in Euclid, Ohio.
Introduction
Seven months before the most consequential procurement deadline in the history of American defense supply chains, REalloys Inc. has moved from letter of intent to binding contract. On May 20, 2026, the Euclid, Ohio-based rare earth processor executed a definitive 15-year offtake agreement with Critical Metals Corp. (NASDAQ: CRML) covering 15% of monthly Phase 1 production from the Tanbreez heavy rare earth deposit in southern Greenland. The announcement came publicly on May 21, 2026, and the deal immediately drew attention from investors, defense analysts, and supply chain strategists tracking the race to build a compliant, non-Chinese rare earth materials pipeline before January 1, 2027.
The strategic weight of the agreement is difficult to overstate. Tanbreez is not simply another rare earth project with favorable press releases. It holds an estimated 28.2 million metric tons of rare earth oxides contained within a 45-million-tonne resource grading 0.4% total rare earth oxides, and approximately 27% of that total rare earth oxide content consists of heavy rare earth elements, primarily dysprosium and terbium. In a global industry where most deposits are dominated by lower-value light rare earths, that ratio makes Tanbreez an outlier of the first order.
For REalloys, which is simultaneously building what it describes as the largest heavy rare earth metallization facility outside China, the Tanbreez agreement converts a line on a feedstock roadmap into a named, permitted, 15-year supply commitment. CEO Leonard Sternheim called it "one of the most significant long-term heavy rare earth supply commitments in the Western hemisphere," and the market responded: Critical Metals shares rose more than 7% on announcement day to $11.51, valuing the company at roughly $1.7 billion.
The Contract Architecture: Terms, Protections, and Strategic Provisions
The Tanbreez offtake agreement, which supersedes and significantly expands the non-binding letter of intent signed by the parties in October 2025, carries a 15-year initial term commencing with first commercial delivery, plus two additional five-year extension options. The Phase 1 nameplate capacity at Tanbreez is publicly disclosed at up to 15,000 metric tons of rare earth concentrate per annum, and REalloys is entitled to 15% of monthly deliveries subject to a plus-or-minus 5% per-delivery operational variance.
Pricing is structured around international rare earth oxide benchmarks on an element-by-element basis, with floor-price protection on specified payable elements. Deliveries are set FOB at the Tanbreez port in southern Greenland, and concentrate must meet agreed product specifications and pass REalloys' qualification protocols before commercial deliveries begin. The contract includes take-or-pay-style protections and default provisions, creating performance obligations for both parties rather than a one-sided option.
Two provisions stand out as commercially significant beyond the headline volume. First, REalloys secured priority access to material with higher concentrations of dysprosium and terbium, meaning the company can direct the most strategically valuable fractions of Tanbreez output toward its metallization operations. Second, REalloys holds a right of first refusal on additional volumes beyond its contracted 15% share. Together, these clauses give REalloys structural leverage that extends well beyond what the raw percentage would suggest.
One material constraint applies: the agreement covers Phase 1 production only. Any subsequent expansion phase at Tanbreez falls outside the current scope, and a five-year long-stop date applies, after which either party may terminate if first commercial delivery has not occurred. That provision creates a development timeline incentive for Critical Metals and a defined risk boundary for REalloys.
Tanbreez: Why This Deposit Changes the Western HREE Calculus
The geological basis for Tanbreez's heavy rare earth richness lies in its classification as a peralkaline rare earth system, a deposit type associated with Arctic and sub-Arctic igneous environments that tend to produce heavier rare earth fractionation than the carbonatite or ionic clay deposits that dominate global production. Most of the world's accessible rare earth production comes from Mountain Pass in California and Bayan Obo in China, both carbonatite systems with light-rare-earth-dominant profiles. Ionic clay deposits in southern China produce the bulk of global heavy rare earth output but are geographically and politically concentrated in ways that now constitute a recognized national security risk for Western governments.
Tanbreez's 27% heavy rare earth concentration is a critical differentiator. A preliminary economic assessment values the project at approximately $3 billion Canadian, with an after-tax net present value ranging from $2.1 billion to $2.7 billion at discount rates of 15% and 12.5% respectively, and an internal rate of return of approximately 180%. Those economics are supported not only by the heavy rare earth profile but by co-production potential in gallium, hafnium, yttrium, and zirconium, all of which carry independent strategic value.
The project's eudialyte-based mineralogy also offers a processing advantage. Eudialyte deposits are typically lower in radioactive thorium and uranium than the rare earth systems that have faced regulatory obstruction in other jurisdictions. Several Greenlandic rare earth projects have encountered sustained opposition on radiological grounds; Tanbreez has navigated that landscape with a mining license granted through to 2050, grounded in its demonstrably lower radioactive contaminant profile and an ESG-aligned development framework.
Logistics reinforce the strategic case. Tanbreez sits on a deep-water fjord that remains ice-free year-round, enabling direct North Atlantic shipping access to refineries in Europe and North America. A new international airport 12 kilometers from the site reduces personnel and equipment transport complexity. For a deposit of this scale, those physical advantages are not minor; they represent the difference between a technically viable resource and a commercially deployable one.
Critical Metals' ownership position adds a final layer of de-risking. In April 2026, the Government of Greenland approved the transfer of the final 50.5% interest in Tanbreez Mining Greenland A/S to Critical Metals, bringing the company's total ownership to 92.5%. The remaining 7.5% is held by European Lithium Limited, and Critical Metals has agreed to acquire that stake in the second half of 2026, which would give it full ownership. The U.S. Export-Import Bank has already issued a letter of interest for a $120 million loan, signaling Washington's view of Tanbreez as a vital component of American mineral security.
REalloys' Ohio Metallization Bet and the Mine-to-Magnet Strategy
Building on my analysis of the Dy/Tb chokepoint in May 2026, REalloys occupies a distinct position in the Western rare earth supply chain precisely because it has targeted metallization, the conversion of rare earth oxide into finished metal and alloy, rather than mining or upstream separation. As REalloys co-founder Tim Johnston has noted plainly: "Most people talk about mining. The bottleneck isn't the mine. It's the step where oxide becomes metal and metal becomes alloy. Metallization is the least developed part of the value chain outside China."
That observation is borne out by the data. China currently controls the overwhelming majority of global rare earth metallization capacity, which means that even ore extracted from domestic or allied-nation deposits must still travel through Chinese refiners before it can become a functional defense-grade material. REalloys' $40 million, fully financed Heavy Rare Earth Metallization Facility in Euclid, Ohio, is explicitly designed to close that gap.
The facility is being developed in collaboration with the Saskatchewan Research Council in Saskatoon, with equipment built there before relocation to Ohio to support the U.S. defense industrial base and contribute to Defense Logistics Agency stockpiles. Initial operations are targeted for early to mid 2027, with full commercial scale expected by mid-to-late 2027. Phase 1 capacity targets are 525 tonnes per year of neodymium-praseodymium metal, 25 tonnes per year of dysprosium, and 12 tonnes per year of terbium. At full buildout, the facility is expected to produce approximately 600 tonnes per year of high-purity rare earth metals.
REalloys' downstream ambition extends beyond metallization. The company is designing a first-phase magnet manufacturing facility capable of producing 3,000 tonnes of neodymium-iron-boron magnets annually, with scaling plans to reach 18,000 tonnes per year. At full capacity, that output could supply magnets for 3 to 4 million electric vehicles annually alongside defense platforms, wind turbines, and robotics systems. The Phase 2 target of 20,000 tonnes per year of heavy rare earth permanent magnets would, if achieved, make REalloys the largest refined dysprosium and terbium producer outside China.
The Tanbreez agreement slots into a diversified feedstock architecture that already includes 100% ownership of the Hoidas Lake deposit in Saskatchewan, an offtake commitment from the high-grade Sheep Creek deposit in Montana, a supply collaboration with St George Mining at Araxá in Brazil, a relationship with AltynGroup at Kokbulak in Kazakhstan, and 80% of output from the Saskatchewan Research Council's commercial rare earth processing facility. REalloys head of R&D Andy Sherman captured the integration logic concisely: "Concentrates are commodities. Materials are commitments." The Tanbreez deal is the largest single feedstock commitment in that portfolio.
The 2027 Deadline, China's Export Controls, and the Price of Compliance
The Pentagon's January 1, 2027 restriction on Chinese-origin rare earth materials is codified in 10 U.S.C. Section 4872 and embedded in DFARS 252.225-7052. Its scope is broader than many defense contractors initially recognized. The rule does not restrict only finished magnets purchased from Chinese suppliers; its traceability mandate extends all the way back through the supply chain to the mine itself. A rare earth element extracted in Montana or Saskatchewan but processed through a Chinese refinery does not satisfy the non-Chinese-origin requirement. Chain-of-custody documentation must be clean and auditable at every stage from extraction to finished component.
The enforcement mechanism is explicit: failure to certify compliance risks contract termination or False Claims Act liability, and the Department of Defense is preparing random spot-checks using tools including X-ray fluorescence. The provision was no accident. Legislators embedded it in the FY2023 National Defense Authorization Act and tightened it in the FY2024 NDAA (Section 854), setting the January 2027 deadline after the 2022 discovery of a Chinese-made samarium-cobalt alloy inside the F-35's turbomachine pump triggered deliveries halt and a national-security waiver from the Under Secretary of Defense for Acquisition and Sustainment.
China's own export control escalation has sharpened Western urgency. On April 4, 2025, Beijing added seven medium and heavy rare earths, including terbium, dysprosium, samarium, gadolinium, lutetium, scandium, and yttrium, to its export control list. Total Chinese magnet exports subsequently fell by 74.3% in volume year-on-year in May 2025. Dysprosium oxide prices rose 27% from the point restrictions began; terbium oxide rose 19%. European prices reached up to six times Chinese domestic prices at their peak.
China later suspended the broader October 2025 export control package until November 2026 as part of post-Xi-Trump trade negotiations, but the April 2025 additions covering dysprosium, terbium, and their compounds remain in force without interruption. Ionic Rare Earths Managing Director Tim Harrison noted the immediate commercial consequence in September 2025: "In the last four months since those export restrictions have been put in place we've been inundated on requests to access the dysprosium and terbium that we've been producing in our demonstration plant in Belfast and selling material now for example dysprosium at three times the price of Chinese-quoted prices in Europe."
The pricing bifurcation between Chinese-origin and documented non-Chinese-origin materials is already a commercial reality, and it is expected to widen further as January 2027 approaches. The Pentagon's floor price of $110 per kilogram for neodymium-praseodymium in its agreement with MP Materials, representing a 70% premium to previous spot prices, signals that the U.S. government is prepared to absorb premium costs to secure provenance-verified supply. For terbium, currently trading above $1,000 per kilogram, and dysprosium at approximately $250 per kilogram, the non-Chinese-origin premium could represent hundreds of millions of dollars annually across the defense industrial base alone.
Market and Competitive Implications
REalloys' Tanbreez commitment arrives in a competitive landscape where only a handful of Western entities are seriously positioned to deliver certified, provenance-clean dysprosium and terbium at commercial scale before 2027. MP Materials is commissioning a dysprosium and terbium separation circuit at its Mountain Pass facility. Australia's Lynas Rare Earths operates a separation facility in Malaysia with announced plans for U.S. processing capability. But neither has publicly committed to a commercial-scale metallization platform for heavy rare earths with the timeline specificity REalloys has provided.
The distinction matters precisely because metallization, not mining and not even separation, is the step that converts a compliant feedstock into a compliant defense material. As REalloys' Sherman observed, the Pentagon does not buy rocks; it buys certified, military-grade materials. The chain-of-custody requirement in DFARS 252.225-7052 means that separation alone is insufficient if the metallization step occurs in a non-compliant facility. REalloys' integrated strategy, combining allied-nation feedstock from Tanbreez and other sources with domestic metallization in Ohio, is designed specifically to satisfy that full-chain requirement.
The commercial validation signals are accumulating on both sides of the partnership. Critical Metals has the U.S. Export-Import Bank's letter of interest for $120 million, the Greenland Government's formal approval of its 92.5% ownership consolidation, and a $30 million acceleration program now underway including a 6,000-meter drilling campaign targeting resource expansion from 45 million tonnes to 130 million tonnes. REalloys has retired General Jack Keane on its board, a $50 million financing commitment covering Phase 1 buildout, and an Export-Import Bank letter of interest for up to $200 million tied to its processing platform.
For the broader Western supply chain, the Tanbreez offtake is significant not only for what it secures but for what it demonstrates: that binding, long-term, commercially structured agreements between allied-nation resource holders and downstream processors are achievable within the compressed timelines the 2027 deadline imposes. That demonstration effect may be as strategically important as the tonnes committed.
Conclusion
The REalloys-Critical Metals offtake agreement is the clearest evidence yet that the race to build a compliant Western heavy rare earth supply chain is moving from roadmap to contract. The 15-year binding term, the priority access provisions for dysprosium- and terbium-rich concentrate, the right of first refusal on additional volumes, and the floor-price structure collectively represent a level of commercial seriousness that distinguishes this deal from the non-binding memoranda of understanding that have historically populated this sector.
Tanbreez's geological profile, the 27% heavy rare earth concentration in a peralkaline system with year-round port access and a mining license through 2050, makes it a genuinely rare asset at a moment of acute scarcity. The deposit's outlier status relative to globally dominant light-rare-earth systems is not a marketing characterization; it reflects a mineral chemistry that cannot be replicated by scaling up carbonatite or ionic clay operations.
The critical uncertainty that remains is timing. REalloys' Heavy Rare Earth Metallization Facility targets initial operations in early to mid 2027, which means the company's commercial-scale production capability will come online near the effective date of the Pentagon ban rather than well before it. As Tim Johnston acknowledged, moving from project to commercial metallization involves multi-year timelines even with strong execution and capital. The five-year long-stop provision in the Tanbreez agreement similarly acknowledges that Greenland production has its own development schedule that does not move at the speed of policy deadlines.
What the agreement does deliver, immediately and unambiguously, is feedstock security with documented provenance from a Western-aligned, permitted, government-backed deposit. In a supply chain where analysts describe the non-Chinese-origin stockpile for some defense applications as covering only a matter of months, that security is not a theoretical advantage. It is a prerequisite for the compliance certifications that will determine which contractors can fulfill DoD contracts beginning January 1, 2027, and which cannot.
