CRML Executes a 15-Year Binding Definitive Off-Take Agreement for Tanbreez with REalloys Inc. Which Supports US Defense & National Security Industrial Base Supply Chains

NEW YORK, May 21, 2026 (GLOBE NEWSWIRE) -- Critical Metals Corp. (NASDAQ:CRML) ("Critical Metals Corp" or the "Company"), a leading critical minerals mining company, today announced the execution of a definitive 15-year binding offtake agreement with REalloys Inc. (NASDAQ:ALOY) for rare earth element concentrate from its flagship Tanbreez Project in Southern Greenland—one of the largest and most significant heavy rare earth deposits globally.

This landmark agreement follows the Government of Greenland's April 17, 2026 approval of Critical Metals' ownership increase to 92.5% of the Tanbreez Project, representing a decisive milestone that fully consolidates operational control and unlocks the project's long-term commercial potential. The agreement formalizes and significantly expands upon the parties' October 2025 Letter of Intent, extending the original ten-year framework into a 15-year binding contract with two additional five-year extension options.

A Defining Commercial Validation of Tanbreez

Under the agreement, REalloys will purchase 15% of Tanbreez's annual rare earth concentrate production, with priority rights in respect of concentrate volumes containing elevated concentrations of the critical heavy rare earth elements dysprosium and terbium, together with a Right of First Refusal over additional volumes.

This long-term commitment underscores the strategic importance of Tanbreez and provides powerful third-party validation of its role as a cornerstone asset in the emerging Western rare earth ecosystem.

With global supply chains undergoing rapid realignment, the agreement positions Critical Metals at the center of a generational shift toward secure, non-Chinese sources of critical minerals—particularly as U.S. defense procurement restrictions coming into force in 2027 mandate the exclusion of Chinese-origin rare earth materials.

Tony Sage, Chairman of CRML, commented:

"This agreement marks a pivotal inflection point for Critical Metals and unequivocally validates Tanbreez as a world-class, development-stage asset of global strategic importance. With 92.5% ownership secured and strong governmental backing in Greenland, we have established full control over one of the most significant heavy rare earth deposits outside of China."

"Partnering with REalloys—a U.S.-based, defense-focused, vertically integrated platform—ensures that our production will directly support the rapidly growing demand for secure, compliant supply chains. This 15-year binding offtake agreement not only underpins the long-term commercial viability of Tanbreez, but also positions Critical Metals as a key supplier to the Western world at a time of accelerating geopolitical and industrial transformation."

Leonard "Lipi" Sternheim, CEO of REalloys, commented:

"This agreement is a defining milestone for REalloys and for the Western rare earth supply chain. With Critical Metals now holding 92.5% ownership of Tanbreez and the full backing of the Greenlandic Government, we are entering this fifteen-year partnership with a single consolidated counterparty that has both the mandate and the resources to deliver. By extending the term, securing priority rights in respect of concentrate volumes containing elevated concentrations of the critical heavy rare earth elements dysprosium and terbium, and establishing a Right of First Refusal on additional volumes, we have transformed a letter of intent into one of the most significant long-term heavy rare earth supply commitments in the Western hemisphere. Combined with our Saskatchewan Research Council partnership, our Hoidas Lake resource, and our Euclid, Ohio metallization platform, REalloys now has feedstock security, processing capability, and downstream manufacturing under one integrated umbrella. This is precisely what the United States requires as the 2027 defense procurement restrictions take effect."

Unmatched Strategic Positioning

Tanbreez is widely recognized as one of the world's premier heavy rare earth and critical metals deposits, distinguished by its high concentrations of heavy rare earth elements dysprosium, terbium, and yttrium—essential inputs for high-performance permanent magnets used in defense systems, electric vehicles, wind energy, robotics, and advanced manufacturing.

In addition, the Tanbreez deposit has significant volumes of hafnium, cerium, lanthanum, niobium and zirconium, which are increasingly important in semiconductor, microchip and advanced technology applications, including infrastructure supporting the growth of artificial intelligence technologies.

By securing a long-term offtake with a U.S.-based, vertically integrated partner, Critical Metals has taken a major step toward monetizing this world-class resource while ensuring alignment with Western defense, energy, and industrial priorities.

The Greenland Government's support and the Company's consolidated 92.5% ownership significantly de-risk project execution, positioning Tanbreez as one of the most advanced and strategically aligned rare earth development projects globally.

Accelerating Toward Production

The agreement strengthens the commercial foundation of the Tanbreez Project as Critical Metals advances development toward first production on an accelerated timeline. In collaboration with REalloys, the Company will optimize metallurgical processes, refine product specifications, and establish efficient logistics pathways to integrate Tanbreez concentrate into downstream processing and magnet manufacturing supply chains.

A Cornerstone Asset for a New Era

As nations and industries prioritize supply chain resilience and independence, Critical Metals is uniquely positioned to deliver long-term value through its ownership of Tanbreez—an asset now firmly established as a cornerstone of the Western rare earth supply chain.

Deliveries under the agreement will be made FOB Tanbreez port in Southern Greenland, with pricing linked to international rare earth oxide benchmarks on an element-by-element basis. Commercial shipments are expected to commence following the start of production.
