The cobalt in the battery economy runs through artisanal mines, and pretending otherwise is the real risk
Most of the world’s cobalt comes from one country, and a meaningful share of it is dug by hand. The Democratic Republic of the Congo supplies roughly 70 percent of mined cobalt, the metal that stabilizes the lithium-ion batteries in phones, laptops, and electric vehicles. Alongside the large industrial operations, hundreds of thousands of artisanal miners work the same mineral belt with shovels, sacks, and no safety equipment. Downstream buyers have spent years trying to wish that second group out of their supply chains. That instinct is the problem, not the solution.
You cannot buy Congolese cobalt and credibly claim no exposure to artisanal production. The two sit in the same geology, often the same concessions, and the material mixes long before it reaches a smelter. A company that writes artisanal cobalt out of its contracts has not removed the risk. It has removed its own visibility into the risk, which is worse. The honest questions are harder. What is the human cost as it actually stands? Is formalization a real path or a way to exclude people from a living? And how do you manage the coexistence of industrial and artisanal mining without either a crackdown or willful blindness? This article takes those questions in order.
The human cost is documented, and it is not old news
The reporting on artisanal cobalt is a decade deep and still accurate in its essentials. In 2016, Amnesty International and the Congolese organization Afrewatch published “This is what we die for.” It was the first detailed trace of how hand-dug cobalt enters the supply chains of some of the wealthiest technology companies on earth. What they found has defined the debate since. Children as young as seven worked at the mines. Miners, adults and children, put in up to twelve hours a day carrying heavy loads for one to two dollars. Between September 2014 and December 2015 alone, at least 80 artisanal miners died underground in southern DRC, and the true figure is almost certainly higher because collapses go unrecorded. Most miners work with bare hands and no masks, breathing cobalt dust that damages lungs and skin.
The scale behind those findings is not marginal. UNICEF estimated around 40,000 children working in southern DRC mines in 2014, many of them on cobalt. Current estimates put roughly 255,000 people in artisanal cobalt mining across the country. These are not statistics a due-diligence memo can dissolve. They describe families for whom mining is the available income in a region with few alternatives, working in conditions that would be criminal almost anywhere else. That combination, real dependence and real danger, is exactly what makes the problem hard. It is also why treating it as a pure sourcing question misses the point. The work is a livelihood and a hazard at the same time, and any serious response has to hold both facts at once. This is squarely human rights territory in a mining zone, not a procurement footnote.
Exclusion feels responsible and makes things worse
When a Western buyer learns what artisanal cobalt involves, the reflex is to ban it. Write a clause requiring industrially sourced cobalt only, demand supplier attestations, and declare the supply chain clean. It looks like the responsible choice. In the DRC it often does the opposite of what it promises.
Exclusion does not stop artisanal mining. Hundreds of thousands of people mine because they need the income, and a purchasing clause in Europe or North America does nothing about that need. What exclusion changes is where the cobalt goes and how visible it is. Barred from formal channels, artisanal material moves through informal traders and gets mixed into larger flows upstream, arriving unlabeled at the smelter. The buyer who demanded exclusion still ends up with artisanal cobalt in its batteries. It simply no longer knows which cobalt, from which site, dug under what conditions. The clause bought a clean conscience and a blind supply chain. The DRC’s own Minister of Mines has put the alternative plainly, framing the answer as formalisation, not exclusion. That is not a soft position. It is a recognition that you cannot regulate what you have pushed into the shadows. The power to improve conditions disappears the moment you stop buying openly. The root causes here are economic, and a rule that ignores the economics cannot fix them.
Formalization is the harder, better path
Formalization means bringing artisanal mining into a legal, monitored structure instead of pretending it away. Miners work organized cooperatives on designated sites, with safety rules, protective equipment, recorded production, and channels to sell into the formal market. The DRC built a state vehicle for this in 2019, the Entreprise Générale du Cobalt, intended to channel and monitor artisanal output. The concept is sound. The record shows both what it can deliver and how fragile it is.
The clearest proof of concept came from the Mutoshi pilot, launched in 2018. The coalition included the mining company Chemaf, the trader Trafigura, the Congolese cooperative COMIAKOL, the nonprofit Pact, and government authorities. The site was fenced. Miners received protective equipment. Women were integrated into the workforce rather than pushed to its margins. Children and pregnant women were barred through controlled entry. During the pilot, no fatal accidents were recorded. For a sector defined by unrecorded deaths, that is a serious result. Then the pilot was suspended in March 2020 as COVID-19 hit, and the momentum stalled. That arc is the honest picture of formalization. It works when the coordination holds and collapses when it does not. The lesson is not that formalization is naive. It is that formalization is a standing commitment, not a one-time certification. It fails the moment the parties treat it as a box to tick rather than a relationship to maintain. Done seriously, it is the only approach that improves conditions while keeping people’s livelihoods intact.
Due diligence is a floor, not a finish line
Downstream buyers face real regulatory and reputational pressure to prove their cobalt is responsibly sourced. The main instrument is the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas. It is a five-step, risk-based framework that asks companies to set policy, map their supply chains, respond to red flags, and stand up grievance mechanisms. It applies to all minerals and is the reference standard buyers are measured against.
The framework is necessary and widely misused. Too many companies run it as a paperwork exercise: collect attestations, file the audit, publish the policy, declare compliance. That satisfies a checklist and changes nothing at the mine. The step most often hollowed out is the grievance mechanism. On paper it is a channel for affected people to raise harm and get a response. In practice it is frequently a form nobody local can reach. A due-diligence program that generates documents while the twelve-hour days and unmarked collapses continue is not managing risk. It is manufacturing deniability. The point of the OECD steps is to drive real engagement with the conditions on the ground, including a working way for miners and communities to be heard. This is the difference between holding a permit and holding genuine permission to operate in a critical-minerals supply chain. Treat the guidance as the floor of what you owe, then build the actual engagement on top of it, or the compliance is theater.
A realistic scenario: an industrial concession with artisanal miners on it
Consider a scenario drawn from patterns common across the Congolese cobalt belt, not any single operation. An industrial mining company holds a concession where several thousand artisanal miners already work, some for years, digging in areas the company has not yet developed. The company faces a genuine bind. Its offtake buyers demand no artisanal cobalt in the product. Its insurers and lawyers see the miners as liability and trespass, and its own managers fear an accident on the concession. The instinct is to clear the site with security.
That instinct is how the worst outcomes begin. Forced eviction of people who depend on the ground for survival does not end mining. It produces confrontation, injury, and a conflict that draws exactly the international scrutiny the buyers were trying to avoid. The alternative is not surrender. It is a negotiated coexistence. The parties, and there are many, include the company, the artisanal miners and their cooperatives, provincial authorities, the state cobalt entity, and often civil-society and buyer representatives. A workable arrangement carves out a defined, formalized zone for artisanal work with real safety standards. It sets the terms on which that cobalt can be sold legitimately. It agrees a schedule and fair process for any future transition as the company develops the area. The industrial operation gets a managed concession and a defensible supply story. The miners keep a livelihood on safer terms. Neither result is available through eviction, and neither is available through pretending the miners are not there. The only path to both runs through a negotiation that treats the miners as parties with legitimate interests, not as a problem to be removed.
Map your artisanal exposure before an audit or an incident maps it for you
Before your next supply-chain audit or your next site incident, it helps to see your artisanal cobalt exposure clearly. The Cobalt Supply-Chain Reality Check is a sectioned diagnostic for buyers and operators. It carries 16 checkpoints across five sections: actual exposure and traceability, human-cost awareness, formalization engagement, OECD due-diligence depth, and coexistence and grievance readiness. You score each one In place, Partial, or Absent, so self-serving assumptions surface as gaps. A cluster of Absent scores in traceability or grievance readiness is the pattern that turns a routine audit into a headline. Use it to replace the comfortable belief that a no-artisanal clause has solved anything, and to find the two or three areas where real engagement would cut the most risk.

Why mediation, and the Social Accord Architecture, fit the cobalt problem
The cobalt question is a coexistence problem, and coexistence problems are not solved by crackdowns or by looking away. A crackdown treats miners as trespassers and produces the confrontation and scrutiny everyone claims to want to avoid. Willful blindness treats the whole issue as someone else’s, which is how twelve-hour days and unrecorded deaths persist inside supply chains that publish responsibility reports. Between those two failures sits the harder, more durable option: a structured, mediated arrangement that reconciles interests no single party can reconcile alone.
Mediation is the discipline that makes coexistence work. An independent, credible facilitator can convene actors who do not trust each other: the industrial operator, the artisanal cooperatives, provincial and state authorities, and downstream buyers. The facilitator holds them to an arrangement that protects miners and gives the company a defensible position. This is the same human-rights-grounded mediation that turns a potential eviction into a negotiated formalization. The Social Accord Architecture is the methodology I use to structure it. The Social Accord Architecture, or SAA, treats coexistence as something you design and sustain, not a truce you hope holds. A Trust Audit shows where credibility has already broken between operators, miners, and the state. A Shared Intent Protocol aligns the parties on the shared goal of safer, legitimate production. A Blueprint and a Resilience Handover give the arrangement enforceable safety terms, a functioning grievance channel, and a fair process for transition as concessions develop. That structure is what lets it survive the shocks that ended pilots like Mutoshi.
The cobalt is not going to stop flowing, because the battery economy depends on it and most of it comes from one place. What is still open is whether the people who dig it by hand are protected and seen, or excluded and endangered while buyers manufacture deniability. Formalization and mediated coexistence are the only responses that improve conditions without destroying livelihoods. Exclusion and crackdown do neither.
