Critical Minerals Must Now Prove It

Signing a critical-minerals deal used to be the achievement. It is now the down payment. On Friday, Congo's Economy Minister Daniel Mukoko Samba told Washington, in effect, that the ceremony is over and the construction must begin.

Speaking in a post on X after the second meeting of the US-Congo joint steering committee in Paris, he said success should be measured by completed projects rather than signed deals, Reuters reported (November 6, 2026), in a report carried by Mining.com. His phrasing was blunter than diplomatic custom: "Our requirement is to move from signed agreements to real investments."

That is the thesis of this piece. Critical-minerals policy has entered its proof phase. Producing countries are demanding delivery, governments are attaching conditions to their money, and domestic opponents are preparing to audit the financing. The physical copper market shows the scarcity behind it all is genuine, so the pressure to deliver is not going away.

Congo asks for steel in the ground

The partnership Washington and Kinshasa signed in 2025 trades expanded US access to Congolese copper, cobalt and other minerals for investment in mining, infrastructure and stability in the conflict-hit east. Early results include the US-backed miner Virtus Minerals, more Congolese copper reaching the US, and Western investor support for the Lobito Corridor to Angola's Atlantic coast, Mining.com reported.

Mukoko Samba's list of priorities shows what Congo thinks is still missing: the Grand Inga hydropower project, local processing, electricity for households and businesses, peace in the east, and reforms to the fiscal framework. Congo is the world's largest cobalt producer and second-largest copper producer, which gives its minister leverage when he asks Washington to show its hand.

Washington's stakes meet a subpoena

The American side of the ledger is under its own audit. The Trump administration has financed critical-minerals companies through equity stakes and stock warrants, and Democratic lawmakers are preparing to investigate those arrangements after the midterms, Bloomberg reported, as relayed by Miningmx.

The exposure is concrete. USA Rare Earth signed a $1.6bn agreement with the Commerce Department in January, including a government stake of roughly 10%. Vulcan Elements received a conditional $620m Pentagon loan commitment and a $50m equity investment months after a venture capital firm linked to Donald Trump Jr. acquired a stake. Kaz Resources, whose indirect investors include Trump's sons, has received preliminary indications of up to $1.6bn in government support. The administration also holds stakes in MP Materials, Lithium Americas and Trilogy Metals.

The Oregon Group puts the total at US$8.6 billion of stakes taken since January 2025, with Project Blue counting more than 160 mineral deals approved in that time. In August, 54 House Democrats warned that the loans and equity investments "shift risk onto US taxpayers while encouraging companies to take on riskier projects," The Oregon Group reports. Project Blue, writing before the vote, said investigations carry significant financial risk for the firms involved, which would incur substantial legal fees defending themselves.

Brazil draws up a list first

Brazil is showing a third way to harden policy: rank first, spend second. On 5 November, a new council known as CIMCE approved an official list of 27 critical minerals in three tiers at its first plenary, The Rio Times reported. The top tier covers rare earths, graphite, lithium, nickel, cobalt, copper, manganese, silicon and uranium.

The list decides who gets money. Under the new policy only projects in listed minerals can receive state financing, guarantees and tax incentives, and a mining guarantee fund can take up to R$2 billion (US$366 million) from the federal government. The selection rests on five tests, among them geopolitical risk, concentration of world supply and import dependence. The Industry Ministry has 15 days to propose priority production chains. Brazil's stated aim is to stop shipping raw ore and build its own battery and magnet industry.

Copper says the scarcity is real

If the scarcity were a story told to win subsidies, copper would show it. This week it did the opposite. The metal fell for a fourth straight session on Friday and was heading for its biggest weekly drop since March, pushed down by a rout in technology stocks, Mining.com reported. Benchmark three-month copper on the London Metal Exchange was down 0.5% at $13,775 a metric ton, after earlier sliding as much as 1.5% to $13,636, its lowest since July 30. Deutsche Bank's Daniel Ghali wrote that "Markets continue to digest implications from a blue wave," a nod to reduced odds of US tariffs on refined copper.

Yet supply concerns limited the downside, and the physical signals are tight. Copper stocks in Shanghai Futures Exchange warehouses fell more than 24% this week to 33,848 tons, the lowest in almost three years and less than a day's worth of Chinese consumption. The Yangshan premium, a gauge of Chinese import appetite, rose to a record $217.50 a ton. The cash LME contract traded at a $181-a-ton premium over the three-month forward, a sign of near-term tightness outside the US.

Equity investors, meanwhile, are pricing in the political risk. COPX, the copper-miners ETF, closed February at $95.70 and ended at $71.25 on Friday, in a session when it advanced 1.45%, according to market data.

The counter-argument

The obvious objection is that none of this threatens the strategy. Existing binding agreements are unlikely to be overturned, Bloomberg reported as relayed by Miningmx. TD Cowen's John Miller told Bloomberg: "I don't think the intent is necessarily to break existing binding legal contracts." The Oregon Group notes that most of Trump's minerals strategy rests on executive action Democrats cannot overturn without beating a veto. Project Vault, the stockpile, has cross-party support, and the SECURE Minerals Act, a US$2.5 billion strategic reserve, is led by a Democrat and a Republican.

All true, and all consistent with the thesis. Support for stockpiles and permitting is bipartisan because those are things the government builds. What is in question is the unfinished and conditional financing, which Bloomberg said faces greater uncertainty. Marex consultant Ed Meir expects some investment plans to pause while earlier agreements are examined. A pause is exactly what Congo's minister is warning against.

The permitting fight shows where the real work lies. The Permitting Council says 50 mining projects now have FAST-41 coverage, 49 of them added under Trump. The Senate returns on Monday, November 9, to vote on whether to take up a bill carrying a bipartisan permitting overhaul, though some senior House Democrats would rather wait until they hold the gavels.

What follows

Our own ClaimWatch data show the ground-level appetite has not gone away: new federal claims ran at 6,758 in May, the latest settled month, against 3,809 in February. BLM records claims about four months late, so that series says nothing about the months since.

If the proof phase holds, the winners will be those with finished mines, signed offtake and a clean cap table. Everyone else will be billing hours. A deal that cannot survive a steering committee, a ranked list or a subpoena was never a supply chain. It was a press release.
