Critical Metals Corp. (NASDAQ: CRML) announced a 15-year binding offtake agreement with REalloys Inc. (NASDAQ: ALOY) for rare earth element concentrate from its Tanbreez Project in Southern Greenland.

Under the agreement, REalloys will purchase 15% of Tanbreez's annual rare earth concentrate production, with priority rights for concentrate containing elevated concentrations of dysprosium and terbium. The deal includes a right of first refusal over additional volumes and two optional five-year extensions.

The agreement follows the Government of Greenland's April 17, 2026 approval of Critical Metals' ownership increase to 92.5% of the Tanbreez Project. The deal expands upon a letter of intent signed in October 2025, extending the original ten-year framework to 15 years.

"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," said Tony Sage, Chairman of Critical Metals.

REalloys CEO Leonard Sternheim stated the agreement represents "one of the most significant long-term heavy rare earth supply commitments in the Western hemisphere."

The Tanbreez deposit contains heavy rare earth elements including dysprosium, terbium, and yttrium, which are used in permanent magnets for defense systems, electric vehicles, and wind energy applications. The deposit also contains hafnium, cerium, lanthanum, niobium and zirconium.

Deliveries will be made FOB Tanbreez port in Southern Greenland, with pricing linked to international rare earth oxide benchmarks. Commercial shipments are expected to commence following the start of production.

The agreement comes as U.S. defense procurement restrictions taking effect in 2027 will mandate the exclusion of Chinese-origin rare earth materials from defense supply chains.
