Welcome back to CMJ,
Here are the 20-second highlights of what we’ll cover:
China’s Ministry of Industry and Information Technology quietly published an enforcement framework for rare earths that institutionalizes its grip on production rather than relying on visible export bans, two weeks before Trump’s scheduled Beijing summit.
Project Vault’s first operational details landed this week, and they look less like a strategic reserve and more like an opening bid. The U.S. Export-Import Bank confirmed the $12B stockpile will source critical minerals globally (including from China) before any preference for domestic or allied supply kicks in.
The DRC went further than any African producer this decade in asserting state control over its mining sector. In a single week, it combined a U.S.- and UAE-funded paramilitary force with a 30-day audit of export revenues.
Critical Metals Corp consolidated 92.5% of the Tanbreez heavy rare earth deposit in a deal valuing European Lithium at roughly $835M, sustaining the pattern of Western capital chasing resource control while leaving the harder problem (separation and metallurgy at an industrial scale), structurally unresolved.
The OECD’s annual export-restrictions inventory confirmed what specialist watchers already suspected: critical minerals weaponization is no longer a uniquely Chinese tool. Myanmar, Sierra Leone, Nigeria, Rwanda, and Argentina are now meaningful contributors.
Capital flows into mining ETFs more than doubled year-on-year to $87.4B by March 31, with $8.24B in net inflows in Q1 alone, suggesting institutional positioning has finally caught up with the supply-chain narrative.
Rare Earths
China’s MIIT framework: the system, formalized
On Tuesday, China’s Ministry of Industry and Information Technology (MIIT) published draft enforcement rules for rare earth producers.Fines up to 5x illegal gains for breaches of mining and separation quotas, license revocation for serious violations.What this brings is ‘institutionalization’ of the imposed controls (now with a real ‘threat’).
Full announcement at: https://www.miit.gov.cn/gzcy/yjzj/art/2026/art_034108edae0b43df95b5d57f9a200dbf.html (please note it’s currently under ‘commentary’ process)
I’d like your attention to the timing, because this matters.The framework dropped roughly two weeks before Trump’s scheduled visit to Beijing. This demonstrates that even after the truce that suspended the October 2025 export controls for one year, China is deepening its institutional grip on the parts of the rare earth complex it already controls.The truce was always partial, we knew that. The seven REEs restricted in April 2025 remain restricted; only the broader October 2025 expansion and export control is paused.
China appears uninterested in normalizing the rare earth market.
The more accurate framing is that it aims to function as the ‘market’s discretionary regulator’, a distinction that has real consequences for how ex-China producers model their downside.
For ex-China producers, this matters because their capital structures are increasingly being underwritten on the assumption that China either restricts heavily or competes fairly.
The actual third option (selective approval of shipments at managed volumes), is harder to model and harder to hedge against. Complexity keeps building.
Project Vault: the missing fine print
Following China’s announcement, on Wednesday, EXIM Chief Banking Officer Brian Greeley disclosed alongside Glencore and Hartree Partners that the $12B Project Vault stockpile (which the administration has positioned as the centerpiece of U.S. critical-mineral resilience) will, in its first operational phase, source materials globally, including from China.The replenishment model that prioritizes domestic production, then allies, only kicks in later.
That matters because the public narrative has been carefully engineered to suggest that Project Vault is a vehicle for funding ex-China supply. The structural reality, as now disclosed, is closer to the opposite in the near term. Based on the disclosed Phase 1 structure, U.S. dollars appear set to procure Chinese metal at scale during the period when domestic and allied capacity is still being built.
You haven’t read it wrong. This is not a contradiction; we see it as an intended mechanism.A working stockpile needs to fill before it can ‘stabilize’.
The disclosure changes how the rest of the architecture should be priced.
If Vault buys Chinese metal in 2026 and 2027, the Pentagon’s $110/kg NdPr floor for MP Materials and Lynas does not have a U.S. government bid sitting behind it during the same window.
The price floor must hold on its own merit, against a market where Chinese suppliers are simultaneously being purchased from (and the question is: will it?)
The Yttrium news from later in the week reinforced this reading.China approved a 60-tonne shipment of Yttrium oxide to U.S. aerospace customers, a volume reportedly around 50% larger than cumulative U.S. yttrium imports since the April 2025 export controls began.That is what a permissioned export system looks like in practice: not a normalized market, but a Beijing-managed faucet.The market clears when China decides it should, in the volumes China decides to allow.
Tanbreez consolidation: capital meets geology
Critical Metals Corp lifted its stake to approximately 92.5% in European Lithium and announced the proposed full acquisition for roughly $835M (0.035 CRML shares per European Lithium share), with the deal also bringing over $200M in cash.The strategic logic is clean: simplify ownership of Tanbreez, one of the largest dysprosium- and yttrium-bearing deposits in the West, to enable financing (especially after the USAR-Serra Verde’s deal).
The harder problem remains unsolved.Tanbreez’s mineralogy is eudialyte, not the bastnasite or monazite that conventional rare earth circuits process. No proven, profitable extraction technique for eudialyte at an industrial scale currently exists.The deposit also sits in southern Greenland, a jurisdiction with complex permitting, limited infrastructure, and elevated radioactivity in the ore body.
The pattern this week is clear: capital continues to flow into resource control, while the actual binding constraint, separation and metallurgy at an industrial scale, remains structurally underfunded.
Again, resources/grades are great, but even better is production certainty.
USA Rare Earth’s $1.6B Commerce package, Serra Verde’s $565M DFC financing, USAR-Serra Verde’s acquisition at $2.8B (covered in last week’s Briefing), the Halleck Creek $456M EXIM LOI, and now Tanbreez at $835M all sit on top of an extraction-and-separation pipeline that, in the West, still has a single (and a half) commercial-scale operator: Lynas (and MP ramping up its separation pipeline). Everything else is in build, demonstration, or permitting.
Copper
The Democratic Republic of Congo (DRC) took two coordinated steps that, taken together, represent the most aggressive assertion of state control over a critical mineral sector since Indonesia’s 2020 nickel ore export ban.
On Monday, the General Inspectorate of Mines announced a $100M paramilitary mining security force, funded jointly by the U.S. and the UAE: 3,000 armed guards by December 2026, scaling to 20,000 by 2028 across all 22 mining provinces.The force will replace conventional defense personnel in mine protection, mineral transport escort, and border security.Structurally, this is a privatized internal-defense layer for the country’s mining sector, paid for by foreign principals (of course, to ‘defend their interests’).
In parallel, President Tshisekedi’s April 25 cabinet directive mandated a 30-day audit of export revenue repatriation and joint-venture financial transparency, with first findings due June 15.The audit is integrated across OGEFREM (Multimodal Freight Management Office), OCC (Congolese Control Office), DGDA (General Directorate of Customs and Excise), the Central Bank, and commercial banks, a vertically coordinated enforcement architecture that DRC has historically lacked.
What is happening in Kinshasa this month is the construction, in real time, of a mineral-state model that combines physical security, financial capture, and governance reform under foreign capital sponsorship.
This is not a normal nationalization. It is a hybrid between state assertion enabled by U.S. and UAE financing, structured around securing supply chains for foreign principals.
For investors in CMOC, Glencore (KCC and Mutanda), Ivanhoe Mines, and Virtus Minerals, the immediate read is mixed:
The smuggling reduction and operational stability are real positives.
The new political risk vector (U.S.- and UAE-funded paramilitary forces in a country with active M23 insurgency and Rwandan involvement), is real and largely unhedged.
Glencore’s Q1 results released Thursday, gave the cleanest numerical view of the moment: copper output up 19% @ 199,600 tonnes, cobalt down 39% @ 5,800 tonnes. The same Congolese asset base is producing in opposite directions, separated only by which mineral is under the ‘new quota regime’. That is what an actively managed extraction policy looks like when applied unevenly across co-products.
The broader Q1 signal was M&A momentum. White & Case reported global mining M&A reached $21.6B in Q1 2026, the strongest start since 2023.Total deal value rose 34% year-on-year and 55% versus Q1 2024. Strategic partnerships are now identified by 32% of survey respondents as the most likely transaction structure in 2026.
Falcon Copper signed a non-exclusive MoU with Glencore for the joint development of U.S.-targeted copper supply chains. Glencore provides capital, logistics, marketing, and offtake; Falcon operates. The financial value was not disclosed, but the message is consistent: trading firms are positioning as ‘origination platforms’ inside the U.S. supply-chain architecture, not merely as trading counterparties.
On the other side, we just had a strong reminder that even Tier 1 jurisdictions and Tier 1 sponsors are seeing capex inflation that breaks original investment cases: South32’s Hermosa cost blowout, over 50% versus the 2024 FID estimate, from $2.2B to $3.3B, with first production at Taylor pushed from H2 FY2027 to H2 FY2028, and nameplate capacity now not expected until FY2031.
Lithium
A USGS-led paper published in Natural Resources Research estimates that the U.S. Appalachian orogen could host roughly 2.33 million tonnes of economically extractable lithium oxide (Li₂O): 900,000 tonnes in the northern Appalachians (Maine, New Hampshire ) and 1.43 million tonnes in the southern Appalachians, based on a companion study.
At the current U.S. net import requirement of about 7.1 kt Li₂O per year, that total would equate to roughly 328 years of supply (though the paper notes that this duration would shorten as lithium demand rises).
The headline is striking, but estimates are at 50% confidence; the 90%-confidence floor is approximately 90,000 tonnes, and the 10% upside reaches 7.4Mt.
These are undiscovered, inferred resources, not developable reserves. The geology is pegmatite, technically tractable but operationally challenging at scale.
The U.S. has the geology to be lithium-independent for several centuries, and three projects under construction.
That gap between resource and capacity is the binding constraint, the same gap that defines rare earths, tungsten, and increasingly the copper smelting complex.
But of course, to develop such capacity, ‘market conditions’ need to be favourable.
For Piedmont, Albemarle, Standard Lithium, Lithium Americas, and the broader U.S. lithium development pipeline, the USGS report is more useful as political ammunition than as a project-level catalyst.It strengthens the abundance argument that pro-mining advocates use against environmental review constraints.It does not shorten any actual project timeline.
Uranium
Kazatomprom’s Q1 2026 operations update reiterated 2026 production guidance unchanged at 27,500 to 29,000 tU (100% basis).The company seems not to be deviating from its value-over-volume strategy, and is targeting a final dividend of KZT 1,292.27 per share at the May 26 AGM (which represents ~75% of free cash flow).
This is a public statement that management sees no compelling internal use for that capital, meaning no accelerated production, no expanded capacity.
Supply discipline is not a talking point. It is now a financial commitment.
The IEA’s 2026 Global Energy Review confirmed that 78 GW of nuclear capacity is currently under construction across 15 countries, against installed global capacity of 420 GW. The Paris Nuclear Energy Summit in March added China, Brazil, Italy, and Belgium to the Triple-by-2050 declaration, bringing the signatory count to 38 governments.
The supply response is being deliberately constrained by the lowest-cost producer while government-led demand commitments expand.
The May 26 dividend authorization is a useful tip: Kazatomprom appears to see no compelling incentive to abandon supply discipline at current prices.
Things You’re Probably Missing (But Shouldn’t)
The OECD’s export restrictions report quietly normalized something important. Critical mineral export restrictions are no longer primarily a Chinese instrument. Myanmar, Sierra Leone, Nigeria, Rwanda, Kazakhstan and even Argentina contributed the largest net additions of new restrictions in 2024. 70% of cobalt and manganese exports, 47% of graphite exports and 45% of rare earth exports are now subject to at least one export restriction.The implication for global pricing models is that the friction layer is structural and broadening, not cyclical.
The Trump-family financial overlap with USG-financed mineral programs deserves more scrutiny than it received.The Financial Times reported on Wednesday that Donald Trump Jr. and Eric Trump hold stakes via a shell company in a U.S. group developing a $1.1B tungsten project in Kazakhstan, the same country that received an EXIM LOI of up to $700M for tungsten development at the February ministerial.The political legitimacy of the bilateral mineral deal architecture depends partly on the perception that capital allocation decisions are being made on strategic merit, not on private exposure.That perception is now harder to sustain.
Almonty Industries relocated its corporate domicile from Toronto to Montana.This sounds like a corporate trivia item, but it is not.Almonty’s move signals that domicile structure has become a meaningful variable in accessing U.S. government capital (EXIM, DOE, DOD, CHIPS, etc).If U.S.-domiciled critical mineral developers begin commanding premium multiples on the assumption of preferential access to USG financing, expect more Canadian and Australian listed miners to follow.The strategic value of TSX and ASX listings for non-precious-metals critical mineral companies looks structurally weaker than it did six-twelve months ago.
Mining ETF AUM more than doubled to $87.4B over the past year, and nearly all of the inflow happened in Q1 2026.$8.24B of net inflows in three months represent the fastest institutional rotation into mining since the 2000s commodity supercycle.BlackRock’s Evy Hambro framed this explicitly as the ‘early stages’ of a new supercycle, with demand diversified across AI infrastructure, electrification, and defense. The risk is that metals futures markets are small relative to global equities ($21T LME annual volume versus $135T S&P 500 futures), so heavy inflows can amplify both upside and downside swings.
Questions we should all be asking
If Project Vault sources Chinese metal throughout 2026 and 2027, does the Pentagon’s $110/kg NdPr price floor function as a genuine market signal? Or does it become a political gesture with no real government bid behind it during the window that matters most?
With USAR-Serra Verde holding the dominant ex-China HREE platform under government-backed price floors, and Tanbreez still years from any processing breakthrough, is Western dysprosium and terbium supply effectively a single-point-of-failure through 2030?
If the DRC’s hybrid model (foreign-funded security plus coordinated state audit) succeeds in stabilizing output and reducing smuggling, does it become a replicable template for other African resource states? And if so, who captures the value: the states, the foreign principals, or the private investors already in the ground?
Kazatomprom has formalized supply discipline through its dividend policy. At what uranium spot price does that discipline break? And is the market pricing the asymmetry correctly?
