Critical Minerals Weekly — Apr 29, 2026

This was the week the scoreboard got published. China's Ministry of Natural Resources released its 2025 mineral data Wednesday — fourteen minerals where China holds the world's largest reserves, seventeen where it leads global production — while Canada quietly turned its federal budget into the price-floor architecture Washington walked away from in January. Meanwhile, a Brazilian court challenge is threatening to unwind the biggest rare earth deal of the year, an Australian regulator blocked a Hong Kong investor from voting its Northern Minerals stake, and Chinese lithium futures surged intraday on what UBS argues is a structurally different cycle. The gap between announcing a critical minerals strategy and operating one has rarely been more visible — or more expensive.

Most government mineral data releases are bureaucratic housekeeping. This one, published Wednesday by China's Ministry of Natural Resources, is closer to a geopolitical press release.

China ranks first in the world in reserves of 14 minerals — including rare earths, tungsten, tin, antimony, gallium, germanium, indium, fluorite, and graphite — and led global production in 17 minerals in 2025, with output exceeding half the global total in 11 of them, according to the ministry. The list reads like a roll call of every Western export-control headache of the past three years.

What changes if Beijing's framing sticks: allied governments lose the rhetorical high ground that "China only dominates because it underprices." The ministry's data reframes Chinese leadership as geological and industrial, not just predatory — which complicates the political case for Western price floors and makes coordinated G7 action harder to sell domestically. What failure looks like for Beijing's narrative: if the November 10 export-control suspension expires without a new framework and Chinese producers face genuine substitution from sodium-ion batteries or seabed-sourced rare earths, the scorecard ages quickly. Watch whether this data gets cited in the next G7 ministerial — it's the kind of number that tends to accelerate allied policy.

The difference between a minerals strategy and a minerals policy is money and contracts. Canada just crossed that line.

Ottawa's new $2-billion critical minerals sovereign fund, announced in this week's federal budget, will back loans, equity stakes, price floors, and offtake agreements. Natural Resources Minister Tim Hodgson confirmed that output from Rio Tinto's scandium plant in Sorel-Tracy and Nouveau Monde Graphite's Quebec project will be stockpiled. Under the price-floor arrangement, Nouveau Monde is guaranteed at least roughly US$1,500 per tonne for large flake graphite and about US$800 per tonne for fine flake, according to The Globe and Mail. The Canada Growth Fund is also putting $25 million into Rio Tinto's scandium operation through a royalty investment plus offtake.

What changes if it works: Canada becomes the jurisdiction where a junior miner can actually finance a midstream plant, with Ottawa acting as buyer of last resort. That's the architecture U.S. miners can't get at home — Reuters reported in January that DOE's Audrey Robertson told minerals executives at a closed-door meeting, "We're not here to prop you guys up." What failure looks like: if eligible projects are limited to majors and the program guidelines (still unpublished) exclude juniors, the fund becomes a Rio Tinto subsidy, not an industrial policy. Watch for Natural Resources Canada's program criteria and whether Nouveau Monde moves up its planned Q1 2027 construction start.

Last week's biggest story just acquired a legal complication.

USA Rare Earth's $2.8 billion acquisition of Brazil's Serra Verde — the ionic clay deposit that was supposed to anchor the first non-Asian heavy rare earth supply chain — is facing a court challenge in Brazil. According to Bloomberg News reporting circulated through Chinese financial press, Brazilian political parties have asked a court to block the sale. The legal theory hasn't been fully publicized, but the pattern is familiar: resource nationalism meeting strategic-asset anxiety in a deposit that produces dysprosium and terbium — exactly the heavy rare earths China restricted in April 2025.

What changes if the challenge succeeds: every Western company eyeing Latin American mineral assets has to reprice political risk, and the U.S.-backed thesis that allied capital can secure non-Chinese heavy rare earths through M&A takes a public hit. What failure looks like for the challengers: a quick procedural dismissal would actually accelerate the deal's symbolic weight as proof-of-concept. Watch whether the U.S. State Department or the Development Finance Corporation weighs in diplomatically — this is exactly the scenario the Minerals Security Partnership was built for, and silence would be telling.

If you rely on Congolese cobalt or copper, your supply chain just got more complicated. The Democratic Republic of Congo has launched a sector-wide mining audit, with officials describing what they call a $16 billion leak in state revenues from battery-metal operations, according to Rare Earth Exchanges' reporting on the Kinshasa announcement.

What changes if the audit holds its political momentum: the era of cheap, low-royalty Congolese cobalt ends. Western and Chinese OEMs alike — who modeled cathode costs on stable DRC feedstock — face renegotiated royalties, forced local-processing stakes, and offtake terms written under Kinshasa's leverage rather than Beijing's. What failure looks like: a quiet settlement with the largest Chinese operators, leaving smaller Western miners stuck with the new rules. Watch which majors are first to agree to local refining commitments before quarter-end — that's the tell on whether this is a one-off shakedown or a structural shift in how Congolese rents get captured.

Canberra's foreign-investment regulator just told anyone using a Hong Kong vehicle to acquire heavy rare earth assets to stop trying.

According to Mining.com, Australia has blocked a Hong Kong-based investor from voting its stake in Northern Minerals — the Western Australian developer of the Browns Range heavy rare earth project — and ordered most of the holding divested. Northern Minerals confirmed the action. This is the second time in recent years Canberra has intervened in the company's ownership structure on national-security grounds. Browns Range produces dysprosium and terbium, and its refinery — financed alongside Japan's Sumitomo Metal Mining — is one of the few operating heavy rare earth projects outside China.

What changes: every fund using Hong Kong as a routing jurisdiction for resource investments in allied countries now has a documented precedent against it. What failure looks like for the policy: if the divestment process drags or the buyer pool is too thin to absorb the stake at fair value, Northern Minerals' share price absorbs the punishment. Watch the secondary buyer list — Japanese and Korean strategic investors are the obvious candidates, and their willingness to step in will tell you whether the allied-capital backstop is real.

The lithium market spent eighteen months killing project financing across three continents. Wednesday, something shifted.

Chinese lithium carbonate futures surged intraday and the lithium-battery sector led a broad rally, with the Shanghai Composite back above 4,100 intraday. Domestic battery production hit a new monthly peak for the third consecutive month, and Q1 energy-storage lithium shipments rose 139% year-on-year, according to Chinese financial press. UBS significantly raised its lithium price forecast, arguing — per Sohu's coverage — that this cycle is structurally different from the 2022–2024 correction. The setup is supply-side: Zimbabwe's raw-ore export ban in effect, production hiccups at Pilgangoora and Greenbushes, and Chinese supply discipline tightening from below while energy storage accelerates from above.

The demand picture has a new component worth naming. According to S&P Global, battery storage is now expected to drive a meaningful share of lithium demand growth globally, and J.P. Morgan analysis circulated by industry outlets puts stationary storage at roughly a third of lithium demand by 2030. Grid-scale buyers — including AI data center developers — are now competing directly with automakers for battery-grade lithium and precursors.

What changes if carbonate holds above $25,000 per tonne through May: stalled midstream projects in Chile, Argentina, and Quebec get their financing case back. What failure looks like: a Chinese supply response or a sodium-ion substitution surprise pulls the floor out before FIDs land. Watch Albemarle and SQM Q2 calls for expansion-decision language.

Most battery launch events look like car-tech theater. CATL's looked more like a map of who keeps pricing power in the next chemistry cycle.

The company unveiled its third-generation Shenxing fast-charging lithium-iron-phosphate battery and confirmed its Naxtra sodium-ion battery is on track for full-scale mass production by the end of 2026, per CATL's announcement. The choices are demand signals in disguise: faster-charging LFP keeps the market tilted toward lithium and phosphate while using less nickel and cobalt, and sodium-ion is the industry's most credible attempt to build a substitute for lower-cost applications.

What changes if automakers follow: lithium, phosphate, and graphite face structurally higher demand in mass-market EVs and stationary storage, while nickel and cobalt growth gets curtailed to premium segments. The technical pivot to watch is whether second-generation sodium-ion approaches roughly 200 Wh/kg — at that threshold, it begins encroaching on light-duty EV applications and most stationary use cases. What failure looks like: sodium-ion stays stuck at backup-power energy densities, and the chemistry remains a niche play. Watch automaker earnings calls in May for echoes of CATL's roadmap.

Beijing published a scoreboard, Ottawa wrote a price-floor blank check, and a Brazilian court hearing now stands between the Pentagon and its dysprosium. The most consequential supply-chain document of the week wasn't a treaty or a tariff — it was a Deutsche Welle story about which German blueprints Chinese license applications are quietly photocopying. Until next week.

If you know someone whose Q3 cathode budget hinges on Kinshasa's mood, forward this along.
