Congo Cobalt Child Labor Audit Reveals Persistent Gap Between Policy and Practice

A comprehensive audit conducted by the Congolese Institute for Nature Conservation (ICCN) in collaboration with the International Labour Organization has revealed that approximately 8,000 children remain actively employed in artisanal and small-scale cobalt mining operations across the Democratic Republic of Congo's Lualaba and Haut-Katanga provinces. The findings, released on April 24, represent a significant setback for multinational corporations and governance bodies that have spent billions of dollars attempting to clean up one of the world's most problematic mineral supply chains.

The audit, which covered 147 mining sites across 23 territories between September 2025 and March 2026, found that children between the ages of 6 and 17 continue to work in hazardous conditions, handling heavy materials, operating rudimentary crushing equipment, and washing ore in toxic slurry ponds contaminated with heavy metals. Respiratory illnesses, musculoskeletal injuries, and neurological symptoms linked to cobalt exposure were documented in 34 percent of child workers surveyed.

Dr. Jean-Pierre Mumbere, the ICCN's lead auditor for the Lualaba province region, described the findings as "a profound indictment of the current compliance architecture." Speaking at a press conference in Kinshasa, Dr. Mumbere stated: "We have verification mechanisms, traceability platforms, corporate codes of conduct, and bilateral agreements. Yet when our teams arrived unannounced at these sites, the reality on the ground had barely changed in five years. The gap between what companies report in their ESG disclosures and what we witnessed with our own eyes is cavernous."

The DRC produces approximately 73 percent of the world's cobalt, a mineral essential for lithium-ion batteries used in electric vehicles and consumer electronics. Global cobalt demand is projected to reach 220,000 tonnes by 2030, up from an estimated 185,000 tonnes in 2025. This surging demand has placed enormous pressure on Congolese mining communities, where an estimated 150,000 to 200,000 artisanal miners work outside the formal sector.

Glencore, the Swiss-based mining and commodities trading giant, operates the Kamoto Copper Company (KCC) and Mutanda Mining in the DRC, collectively producing over 40,000 tonnes of cobalt annually. In response to the audit findings, Glencore's head of responsible sourcing, Margaret Thornton, issued a statement acknowledging "shortcomings in the downstream monitoring of artisanal mining zones adjacent to our concession areas." Thornton stated that Glencore would commit an additional $45 million over three years to expand its Responsible Artisanal Cobalt Initiative (RACI), which aims to formalize artisanal mining cooperatives and establish child-free zones within a 15-kilometer radius of industrial operations.

However, critics have questioned the efficacy of such initiatives. Sarah Mbala, director of the Kinshasa-based human rights organization Afrewatch, pointed out that Glencore's previous commitments totaling $120 million since 2020 had failed to produce measurable reductions in child labor. "These are well-intentioned programs that create excellent press releases and glossy sustainability reports," Mbala said. "But they do not address the fundamental economic reality: families send their children to mine because they cannot afford not to. A cobalt washer can earn between $2 and $5 per day, which in a household of six or seven people is the difference between eating and starving."

The audit revealed that the average household income in communities surrounding major cobalt mining sites is approximately $1.80 per person per day, well below the World Bank's extreme poverty threshold of $2.15. School enrollment rates in these areas have declined by 12 percent since 2022, a period that coincided with a sharp increase in cobalt prices from $33,000 per tonne to a peak of $52,000 per tonne in mid-2025.

The Congolese government has faced criticism for its enforcement posture. Minister of Mines Kizito Pakabomba acknowledged in a parliamentary address on April 22 that the government's capacity to monitor artisanal mining sites was "gravely insufficient." The country has approximately 2,600 mining inspectors responsible for overseeing a sector that spans an area larger than Western Europe. "We have the laws on paper," Pakabomba said. "We have the mining code of 2018, which strictly prohibits child labor. Enforcement is another matter entirely."

International buyers have responded with renewed scrutiny. Apple, which sources cobalt through refiners linked to DRC operations, announced on April 20 that it would expand its supply chain auditing program to include unannounced third-party inspections at artisanal mining sites identified by the ICCN audit. Samsung SDI and CATL, two of the world's largest battery manufacturers, signaled similar intentions. The London Metal Exchange has indicated it may tighten its responsible sourcing requirements for cobalt brands listed on the exchange.

The EU's Critical Raw Materials Act, which entered into force in 2024, mandates that 10 percent of the bloc's annual consumption of strategic minerals must come from recycled sources by 2030 and 40 percent must be processed within the EU. These requirements were designed in part to reduce dependence onartisanal mining in conflict-affected regions, but implementation timelines remain far behind schedule. Only three cobalt recycling facilities of commercial scale are currently operational in Europe, processing a combined total of approximately 8,000 tonnes annually -- a fraction of the EU's 45,000-tonne annual consumption.

Meanwhile, Chinese firms continue to dominate the DRC's cobalt refining sector, controlling an estimated 68 percent of the country's cobalt processing capacity. Companies such as CMOC Group, Huayou Cobalt, and Zhejiang Huayou have invested heavily in DRC operations but have faced less coordinated pressure from Western consumers and regulators regarding labor practices.

Professor Patience Mususa, a mining governance researcher at the University of Cape Town's Minerals to Nations initiative, argued that the audit findings underscore a deeper structural failure. "The entire cobalt supply chain governance model is built on voluntary compliance and corporate self-regulation," she said. "Until there are legally binding obligations with real penalties -- trade sanctions, import bans, criminal liability for executives who source from tainted supply chains -- we will continue to see these audit reports every few years with the same grim findings."

The ICCN audit recommended 23 specific measures, including the establishment of a $500 million multinational fund financed by cobalt buyers to support alternative livelihoods, school construction, and healthcare in mining-affected communities. It also called on the DRC government to deploy mobile inspection units equipped with biometric verification technology to track workers at artisanal sites, and for the creation of an independent international monitoring body with the authority to issue binding remediation orders to mining companies.

Whether these recommendations will translate into action remains uncertain. The last major audit of DRC cobalt mining, conducted by the Responsible Minerals Initiative in 2023, produced a similar set of recommendations. Of the 19 measures proposed at that time, only four have been fully implemented as of April 2026. For the estimated 8,000 children still working in Congo's cobalt mines, the gap between policy and practice is not an abstract governance problem -- it is the reality of their daily lives.
