Ucore-Critical Metals LOI: A Heavy-REE Shot Across the Bow

Highlights

• Ucore Rare Metals and Critical Metals Corp are negotiating a potential rare earth supply agreement for U.S. strategic metals processing.
• The proposed partnership aims to support U.S. government efforts to reduce dependence on Chinese rare earth supply chains.
• A non-binding letter of intent involves the potential delivery of 10,000 tpa heavy rare earth concentrate to a facility in Louisiana.

Ucore Rare Metals (TSXV: UCU; OTCQX: UURAF) signed a non-binding LOI with Critical Metals Corp (NASDAQ: CRML) for Tanbreez feedstock from southern Greenland into Ucore’s Strategic Metals Complex (SMC) in Alexandria, Louisiana, with initial volumes to be trialed at Ucore’s Kingston, Ontario CDF. Start date: the later of July 1, 2027 or Tanbreez commercial production. Product: mixed rare earth carbonate/oxide, specs TBD.

Signal vs. Substance

Critical Metals expects to supply up to 10,000 tpa of heavy-REE concentrate (≈10% of Tanbreez’s initial projection). Ucore’s DoD-backed plant targets 2,000 tpa oxides in 2026, scaling to 7,500 tpa by 2028 (company guidance cited by Reuters). EXIM also issued a $120M LOI for Tanbreez financing in June. If executed, this is meaningful HREE optionality for a U.S. node.

The Fine Print They Didn’t Lead With that Investors Should be Aware of

• Non-binding: Parties still must complete diligence, nail down volumes/specs/pricing, and sign a definitive offtake. Until then, it’s intent, not revenue.
• Timeline tension: Ucore’s output aspiration begins 2026, but LOI deliveries begin 2027+—investors should ask what feeds the SMC in year one.
• Tanbreez project maturity: Critical Metals only recently engaged NIRAS to finalize the DFS; mine build, permits, and logistics remain on the path ahead.
• Funding reality: Ucore has a US$18.4M DoD award toward SMC scale-up; the total capex and financing stack to commission and ramp to multi-ktpa remain to be fully detailed.

Why It Matters (And What We’ll Track)

This is the right direction for a U.S. heavy-REE chain: a North Atlantic mine concept linked to a DoD-supported U.S. separator. It also aligns with Washington’s push to dilute China’s dominance in magnet-critical elements (Tb/Dy), where Ucore has reported successful demo-scale separations. Execution—permitting, financing, logistics, and binding terms—will decide whether optionality turns into cash flow.

Investor Questions That Decide Value

1. Binding Terms: What volume bands, take-or-pay, and pricing indexation will the definitive deal carry? (The LOI is silent.)
2. Schedule Fit: What interim feedstocks fill Ucore’s 2026 production targets before Tanbreez deliveries begin?
3. Project Readiness: What’s the DFS timeline, permitting status in Greenland, and port/shipping plan from southern Greenland to Louisiana?
4. Capital Stack: Beyond the US$18.4M DoD tranche, what equity/debt bridges SMC to commercial run-rate—and on what milestones?
