USA Rare Earth and the Heavy Rare Earth Realignment

Below is a structured synthesis of the most important recent developments in rare earths, grouped by theme, with an emphasis on supply chain, mining operations, and geopolitics.

1. USA Rare Earth emerges as a flagship Western mine‑to‑magnets contender

Headline event: USA Rare Earth secures US DOE backing and pushes into Brazil’s only producing rare earth mine

The US Department of Energy has selected USA Rare Earth (Nasdaq: USAR) to receive up to $19.3 million in federal funding for a pilot‑scale rare earth separations project in the United States.1610 The project falls under DOE’s Critical Materials Innovation, Efficiency and Alternatives program and targets mid‑stream processing capacity for rare earths used in energy, defense and advanced manufacturing.1810

Key elements and implications:

- Pilot separations plant in the US
The DOE‑backed project is designed to demonstrate a continuous ion exchange (CIX) based separation technology as an economical, more environmentally benign platform for US rare earth refining.10 If successful, it could provide a domestic processing route that avoids traditional solvent extraction, which is capital intensive and environmentally sensitive.

- Public funding leverages larger private capital
Total project value is about $50.5 million, of which $31.2 million is non‑DOE funding, signaling substantial private capital alongside government support.1 This aligns with Washington’s strategy to use relatively modest grants to de‑risk early stage midstream projects.

- Stacked US government support
In addition to DOE’s grant, USA Rare Earth previously received $1.6 billion in proposed funding from the US Department of Commerce, contingent on milestones for its core projects, which suggests the company is being positioned as a central node in US critical mineral policy.1

- Serra Verde acquisition as heavy rare earth anchor
USA Rare Earth recently announced a $2.8 billion deal to acquire Brazil’s Serra Verde, owner of the Pela Ema rare earth mine in Goiás state.1 Serra Verde is Brazil’s only producing rare earth mine and one of the very few operations outside China capable of large‑scale heavy rare earth production, including dysprosium and terbium.1

Serra Verde has indicated that the mine could account for roughly half of global ex‑China heavy rare earth output by 2027, underscoring how central this asset is to non‑Chinese supply of magnet‑critical heavy REEs.1

- Long‑term US offtake baked into the transaction
The acquisition includes a 15‑year US offtake agreement covering neodymium, praseodymium, dysprosium and terbium.1 This directly links Brazilian mine output to US customers and defense‑adjacent industries, reducing exposure to Chinese intermediaries.

- Regulatory risk in Brazil
Brazil’s antitrust watchdog has opened an investigation into the proposed Serra Verde acquisition.1 For investors, this is the main transactional risk. If cleared, USA Rare Earth will control Brazil’s only producing rare earth mine and effectively a cornerstone ex‑China heavy rare earth asset.

Strategic takeaway: USA Rare Earth is transitioning from a development story into a vertically integrated mine‑to‑magnets platform that could serve aerospace, defense, semiconductors, clean energy, and data center markets.16 US government support and the Serra Verde deal together represent one of the most consequential non‑Chinese heavy REE moves in years.

2. Critical Metals’ Tanbreez offtake cements Greenland as a heavy REE pillar

Headline event: Critical Metals locks in 15‑year offtake from Tanbreez to REalloys ahead of US 2027 China bans

Critical Metals Corp. (Nasdaq: CRML) announced a binding 15‑year offtake agreement with REalloys Inc. (Nasdaq: ALOY) for rare earth concentrate from the Tanbreez Project in Southern Greenland, widely described as one of the largest heavy rare earth deposits globally.2

Key details:

- Ownership consolidation in Greenland
Following approval from the Government of Greenland on April 17, 2026, Critical Metals increased its ownership of Tanbreez to 92.5%, gaining full operational control.2 This was a key derisking step that unlocks long‑term project financing and commercial negotiation.

- Structure of the offtake
REalloys will purchase 15% of Tanbreez’s annual rare earth concentrate production.2 Importantly, the contract gives REalloys priority rights over volumes rich in dysprosium and terbium and a Right of First Refusal on additional volumes.2 Pricing is linked to international rare earth oxide benchmarks on an element‑by‑element basis, which limits pricing opacity.2

- Term length and extensions
The agreement extends an earlier 10‑year LOI (October 2025) into a 15‑year binding contract, with two additional 5‑year extension options.2 This could effectively become a 25‑year supply relationship, a duration that matches the life of major magnet plants.

- Timing of shipments
Deliveries will be made FOB Tanbreez port in Southern Greenland, with first commercial shipments expected after mine start‑up.2 While no precise production date is given, the offtake’s detailed terms suggest the parties are working toward financing and construction decisions.

- Geopolitical overlay: US defense sourcing rules
The announcement explicitly ties Tanbreez’s strategic relevance to US defense procurement restrictions coming into force in 2027, which will exclude Chinese‑origin rare earth materials from key US defense supply chains.2 With global supply chains realigning, the agreement positions Tanbreez as a non‑Chinese heavy REE source tailored to those restrictions.2

Strategic takeaway: Tanbreez, alongside Serra Verde, is emerging as a core pillar of non‑Chinese heavy rare earth supply. The REalloys offtake is not just a commercial win; it is calibrated to the 2027 US defense ban on Chinese‑origin rare earths and sets a template for long‑dated Western heavy REE contracts.

3. China’s new five‑year plan: more dominance, tighter controls

Headline event: China signals plan to strengthen rare earth sector and tighten export control regime through 2030

China’s 15th Five‑Year Plan explicitly states that it will “strengthen the competitiveness” of its dominant rare earth industry over 2026 to 2030.4 It also commits to enhancing and improving export control systems covering strategic minerals.4

Key dimensions:

- Reinforcement of upstream and midstream dominance
China currently controls roughly 70% of global rare earth mining and processes 85–90% of global supply.3 The new plan aims to safeguard and enhance this position, likely through further consolidation of state‑owned champions, stricter production quotas and technology upgrades.

- Export controls as an explicit policy tool
Beijing has already used export restrictions on gallium, germanium, antimony and several rare earths from late 2024 onward.34 Although a US‑China rare earth truce in November 2025 paused formal controls on some elements, customs data indicates China is still throttling shipments in practice, keeping supply tight and prices elevated.3

- Tighter system, not looser
The five‑year plan’s language on export controls suggests institutionalization rather than relaxation of controls.4 Markets should assume that export permits, quotas and opaque customs practices will remain a structural risk rather than a short‑term bargaining chip.

Strategic takeaway: China is moving from episodic export controls to a more structured and durable regime. For Western buyers, this cements the logic of long‑dated offtakes and stockpiles, and it supports a higher structural risk premium in rare earth prices.

4. US‑China “truce” on rare earths: time bought, not dependence solved

Market commentary highlights that a one‑year US‑China rare earth truce is in place through November 2026, but China is still limiting shipments and maintaining de facto tightness in the market.3

Key points:

- Scope of the truce
Restrictions introduced in late 2024 and expanded through 2025 covered gallium, germanium, antimony and several rare earths.3 The November 2025 truce paused some of these measures, but it did not dismantle China’s leverage nor its ability to slow exports administratively.3

- Ongoing practical throttling
Customs data indicates that shipments remain constrained, which keeps shortages persistent and prices elevated.3 This supports margins for non‑Chinese producers and prospective producers but increases costs for downstream manufacturers.

- Corporate hedging behavior
Major US corporations are responding directly to this volatility. Apple CEO Tim Cook has reportedly struck a supply agreement with MP Materials to source domestically produced rare earths.3 This signals large OEMs are beginning to internalize geopolitical risk into procurement strategies.

- Implications for developers
Market analysis highlights Critical Metals Corp., USA Rare Earth, and American Rare Earths as development‑stage companies that stand to benefit from a government‑backed price floor and the urgency to diversify away from China.39

Strategic takeaway: The truce is functioning as a temporary pressure valve, not a structural solution. It buys time for Western projects like Tanbreez and Serra Verde to advance, but does not remove the strategic imperative for alternative supply.

5. Policy architecture: DOE and allied governments harden critical mineral strategies

The US DOE’s broader critical minerals strategy frames many of the funding and project selection decisions we are seeing in rare earths.810

Key elements:

- Four‑pillar DOE strategy
DOE organizes its approach around:
1) Diversifying supplies of critical minerals and materials.
2) Developing alternatives to critical materials.
3) Improving materials and manufacturing efficiency.
4) Investing in recycling and reuse.8

Rare earths and magnet materials sit squarely inside pillar 1 (diversification) but increasingly intersect with pillar 4 (recycling), especially for defense and EV applications.8

- Recognition of US supply gaps
DOE explicitly notes that the US lacks a strong domestic supply of rare earth elements, lithium, cobalt, high purity nickel, and several other critical inputs for energy and manufacturing.8 This is the policy backdrop for the USA Rare Earth pilot and similar awards.610

- Project selection logic
In its FOA 3105 project list, DOE singles out USA Rare Earth for developing CIX‑based separation as a platform technology for the US REE industry.10 The focus on process innovation suggests an attempt to leapfrog legacy Chinese solvent extraction practices.

Outside the US, the EU is also moving toward rare earth stockpiles and new supply agreements as China tightens its grip, though recent detailed announcements are sparse.7 This is consistent with the EU Critical Raw Materials Act, which sets targets for minimum domestic and allied sourcing.

Strategic takeaway: Policy is no longer only about R&D grants. It is now explicitly about industrial strategy, with governments co‑selecting future winners in the rare earth midstream and supporting them with offtakes, risk‑sharing and export control responses.

6. Price environment and market sentiment

Private investor reference prices for rare earths and technology metals, last updated May 22, 2026, show that prices remain elevated relative to pre‑2024 levels, reflecting continued supply tightness and geopolitical risk premia.5

While the detailed price slate is proprietary, the key signals for industry analysis are:

- Structural support for magnet‑critical oxides (NdPr, Dy, Tb) due to the combination of China’s export behavior and slow ramp‑up of non‑Chinese capacity.35

- Investors are increasingly pursuing equity exposure to rare earth developers, as reflected in recent coverage of “best rare earth stocks” and thematic baskets targeting critical minerals.39

For producers and advanced developers, the current price environment is supportive of FID decisions, provided they can secure long‑term offtake.

7. Forward‑looking implications for the rare earth supply chain

Pulling the threads together, several medium‑term themes stand out:

- Bifurcated supply chain
The world is moving toward a China‑centric system and a US/allied system. Tanbreez (Greenland), Serra Verde (Brazil), and US‑based processing pilots are the early anchors of the latter.1234

- Heavy rare earths as the main chokepoint
Both the USA Rare Earth–Serra Verde strategy and Tanbreez’s marketing focus on dysprosium and terbium, reflecting their outsized importance for high‑temperature magnets and defense systems.12 These are likely to remain structurally tight.

- Long‑dated offtakes and defense procurement rules as price floors
Fifteen‑year offtakes, plus upcoming US bans on Chinese‑origin rare earths in defense supply chains, should underpin a long‑term demand base for ex‑China projects, even if cyclical downturns occur.23

- Technology as a differentiator
DOE’s push for CIX and other cleaner processing methods suggests that process technology and ESG profile will be commercial differentiators. Projects that can combine competitive costs with low environmental footprint will have an advantage in winning Western capital and offtake.

For a senior industry analyst, the key watchpoints over the next 12–18 months are:

- Brazilian regulatory outcome on the Serra Verde acquisition and the pace of its capacity ramp.1
- Final investment decisions and project financing milestones at Tanbreez following the REalloys offtake.2
- Implementation specifics of US defense procurement restrictions in 2027, including how “Chinese origin” is defined across complex magnet supply chains.23
- The detailed implementation rules and quotas that follow China’s 15th Five‑Year Plan, especially any new export control categories.4

Collectively, these developments point to a rare earth market where policy, not just geology and cost, will drive value creation and risk for the foreseeable future.
