Evidence from 214 African value-addition projects since 2000 shows that a signed buyer, not capital or state backing, decides which African mineral plants get built.

African ministers love a launch ceremony. A new refinery, a battery-precursor plant, a smelter to keep value at home. Western governments and development banks match the mood, pledging billions for critical minerals. Yet most announced projects are never built.

The reason is uncomfortable. The binding constraint is not money. It is a buyer. Multilateral analysts agree that bankability, not capital availability, is the binding barrier in critical minerals today.

I examined 214 African mineral value-addition projects announced or active since 2000, from first beneficiation through smelting, refining and cathode, anode and rare earth production. Pure direct-shipping ore is excluded. For each project, I asked one question. Did it reach financial close the moment funding was secured and construction could begin, or did it stall after the announcement stage? The pattern is not subtle.

One factor towers over the rest

A binding offtake, a signed contract by a buyer to purchase the plant's output, was the strongest marker of success. Among projects launched between 2015 and 2025, 88.1 per cent of those with a signed buyer reached financing. Among those without one, the figure was 1.5 per cent. Almost every project with a buyer got built. Almost none without one did.

Figure 1. Projects with a binding buyer closed at 88.1 per cent. Those without one closed at 1.5 per cent.

This is not a quirk of one period. Across the full 26 years, 96 per cent of projects with a binding buyer reached close. Only 1 per cent without one did. A signed buyer is a key precondition for financing African mineral processing.

The Peterson Institute for International Economics reached a similar conclusion in March 2026, framing bankability as a problem of three beholders: sponsor, lender and buyer. The buyer does the heaviest lifting.

 Why a buyer, and not capital

Financiers do not fund slogans or geology. They fund cash flows they can predict. A signed buyer turns an uncertain commodity bet into a contracted revenue stream a bank can model and lend against. That is the whole logic of project finance. The buyer carries the demand risk that would otherwise sink the loan.

Two African cases make the point. Syrah Resources' Balama graphite mine in Mozambique feeds its Vidalia anode plant in Louisiana, which holds a Tesla offtake for anode material. That buyer chain unlocked a US$150 million loan to Balama from the US International Development Finance Corporation. The deal has since come under stress, with DFC moving toward an equity position. The point holds. The loan would never have come without the Tesla contract.

Ivanhoe and Zijin's Kamoa-Kakula copper complex in the DRC, the continent's largest greenfield copper development, anchors its multi-billion-dollar debt and equity stack on long-term offtakes with CITIC Metal and Zijin's smelting network.

Compare both with Huayou Cobalt's $422 million purchase of the Arcadia lithium operation in Zimbabwe, built because the same firm refines and consumes the output downstream. The offtake sits inside the company. Three projects, three structures, one common feature. The buyer was identified before the financing was sought.

This reframes a common mistake. Governments and promoters treat capital as the bottleneck. They chase concessional finance, sovereign funds and headline pledges. The evidence says capital follows bankability, not the other way round.

Supply is the second gate

A buyer is the first gate. Secured feedstock, the raw material a plant needs to run, is the second. In the recent period, projects with secured feedstock closed at 46 per cent, compared with 13 per cent for those without it. Projects that opened both gates closed at 91 per cent. Projects with neither closed at zero. A refinery with a contracted buyer and a captive mine is a financier's dream. A plant with neither is a press release.

Figure 2. The two-gate test. Both open: 91 per cent close. Neither open: zero close.

 

 The export-ban reflex solves the wrong problem

Many governments reach for export bans and forced-processing rules to drive value addition. Zimbabwe's 25 February 2026 ban on exports of raw minerals and lithium concentrate, announced without a matching refining base or buyer pipeline, is the latest example. Across 26 years, no government-mandated processing project reached financial close. Zero out of sixteen. Such tools raise policy risk without solving the buyer problem. A ban can strand a mine with no one to buy its refined output.

What this means for executives

Lead with the offtake. A signed buyer, even a modest one, does more for your financing case than another investor roadshow. The buyer can be an OEM, a battery or alloy maker, an agro-processor or a strategic industrial partner. Build the chain first. The capital conversation becomes far easier once a credible buyer is in the room.

 What this means for governments

Judge projects by financial-close readiness, not by announcement volume. Screen every project against a short bankability checklist: feedstock, a credible buyer, a capable sponsor, infrastructure, permits and a financing path. Then put public money where it pays. A few tens of millions for feasibility studies, ESG compliance and buyer matching, not another mega-fund.

 An honest caveat

This is an observed association, not an experiment. Successful projects publicise their buyer contracts while stalled ones stay quiet, so the buyer signal partly marks an already sound deal. Yet the pattern is so stark, and holds across so many checks, that ignoring it would be reckless.

 The bottom line

Africa's mineral ambition is real, and the window is narrow. The fastest way to turn announcements into assets is not another capital pledge or another export rule. It is a buyer. Find the buyer first, and the money will follow.
