EXTRACTION / Resources & Sovereignty
In May 2026, Barrick confirmed to Reuters that it had stepped up Ebola screening at the Kibali gold mine in Haut-Uele Province, DRC, noting that some of its employees and contractors originate from the affected Ituri Province. As of June 2, 2026, the DRC Ministry of Health had confirmed 344 cases of Ebola disease caused by Bundibugyo ebolavirus, with Ituri as the primary epicentre. The Kibali announcement is the most visible corporate disclosure from a major industrial operator. But the more consequential supply chain exposure from this outbreak runs not through large-format gold operations with biosecurity infrastructure and enclosed camp logistics, but through the artisanal and small-scale mining networks that supply the global technology sector’s most concentrated inputs from eastern DRC. The geography of the outbreak and the geography of critical mineral production are, in this case, the same map.
The mineral exposure is specific and documented. Eastern Congo holds over 40% of the world’s coltan, from which tantalum is extracted for the capacitors that regulate electrical power in consumer electronics. Tin from the region is used in the solder that holds circuit boards together. The Rubaya mine in North Kivu alone accounts for about 15% of global coltan output. M23 took full control of it in April 2024 and collects an estimated $800,000 per month taxing coltan, tin, tungsten, and manganese. The Rubaya deposit suffered a further shock in January 2026, when a landslide killed more than 200 people and caused an immediate spike in tantalite prices in Rwanda as the flow of material from the site paused. The structural tantalum exposure runs through Rubaya, with tantalum concentrations of 20 to 40%. The site was already operating under compounded stress, combining M23 revenue extraction with the aftermath of the January collapse, before the Ebola outbreak added a third layer of disruption.
The tin exposure is concentrated in a single operation. Alphamin Resources’ Bisie mine in Nord-Kivu produced a record 18,576 tonnes of tin in 2025, approximately 6.3% of global mined tin supply. The mine resumed operations in mid-April 2025 after a five-week suspension linked to M23 advances toward the site. Alphamin’s 2026 production guidance stands at approximately 20,000 tonnes of contained tin. Bisie’s concentration in global supply means that any disruption at a single site has measurable market consequences. The World Bank projected average tin prices of $34,000 per tonne in 2026, with demand driven by semiconductor production, photovoltaic solar panels, and electronics manufacturing. An Ebola-driven disruption at Bisie would tighten an already concentrated tin market. That market is structurally thin: Indonesia and Myanmar, the other significant tin sources, have their own supply uncertainties. Bisie is not a marginal producer. It is a swing supplier in a market with limited redundancy.
The analytical distinction between large-format industrial operations and artisanal supply chains is where the supply chain risk is most precisely located. Barrick’s Kibali operation has enclosed accommodation, medical facilities, and established biosecurity protocols that it demonstrated during the 2018 to 2020 Ebola outbreak in DRC. The risk to Kibali from a disease outbreak in a neighbouring province is real but manageable through screening, movement restrictions, and workforce monitoring. The risk to Rubaya and to the wider artisanal coltan network in North Kivu is categorically different. The Ituri Province’s combination of tropical forest ecosystems, high wildlife-human interface zones, and dense populations with limited healthcare infrastructure creates conditions where outbreak containment is structurally difficult. The provinces with the highest mineral wealth, Haut-Uele, Ituri, North Kivu, and South Kivu, are precisely those with the strongest historical association with Ebola outbreaks. This is not coincidental geography. Mining and agricultural expansion push human populations deeper into forest margins, increasing contact rates with wildlife species that serve as natural reservoirs for filoviruses. The economic geography that makes eastern DRC one of the world’s most valuable mineral zones is the same geography that makes it one of the world’s most persistent outbreak environments.
Years of conflict driven by militias have left more than two million people internally displaced in Ituri and North Kivu provinces, many already weakened by severe malnutrition. Large-scale refugee movements and cross-border travel, as well as mining-related travel, complicate contact tracing efforts. Healthcare workers have been attacked. Ituri’s status as a commercial and migratory hub greatly increases the risk of the disease spreading to the broader region. For artisanal miners, who move between sites following ore deposits and who live in communities without the biosecurity infrastructure that industrial operations can deploy, movement restrictions are operationally equivalent to mine closure. A miner who cannot travel to a site cannot produce. An intermediary who cannot collect cannot export. The coltan supply chain from Rubaya to the Rwandan processing centres to the global spot market depends on physical mobility at every step. Mobility restrictions, even partial ones, translate directly into volume reductions.
BMI, the Fitch Solutions subsidiary, assessed the macro exposure in its June 2026 note: the Ebola outbreak is unlikely to have a major impact on copper and cobalt operations in the south and centre of the DRC, where Kamoa-Kakula, Tenke Fungurume, and the Katanga operations are geographically isolated from the Ituri and North Kivu epicentres. The real risk, BMI concluded, is concentrated in artisanal coltan and tin mining in the northeast. That assessment aligns with the geography. The copper and cobalt operations that dominate the DRC’s formal mining sector and that are tracked in the Washington Accords framework are hundreds of kilometres from the outbreak zone. The 3TG minerals, tin, tantalum, tungsten, and gold, that feed the global electronics supply chain through artisanal networks are in the affected provinces.
The US strategic mineral partnership with Kinshasa signed in December 2025, and the 44-project shortlist that Washington has prioritised in the DRC, were designed around copper, cobalt, and critical battery materials from the Katanga region. They were not designed around the 3TG supply chains of North Kivu and Ituri. That design choice now looks like a structural gap. The technology sector’s tantalum inputs, without which capacitors cannot be manufactured and consumer electronics cannot function, flow primarily through artisanal networks in the same provinces where the Bundibugyo outbreak is active, where M23 revenue extraction has been operating for two years, and where the Rubaya mine suffered a catastrophic collapse in January 2026. These are not separate risks. They are the same geography under three simultaneous stressors.
The DRC constitutional crisis documented in this series adds a fourth layer. The June 9, 2026 referendum bill, passed 289 to 1 and designed to create a path toward a presidential third term, absorbs political bandwidth in Kinshasa at the moment when coordinated outbreak response in eastern provinces requires functional institutional alignment between the central government, provincial health authorities, and security forces. The constitutional tension does not directly impede mine production. It does affect the government’s capacity for rapid, coordinated response in the provinces most affected by the outbreak. And in a context where healthcare workers have been attacked and contact tracing is complicated by conflict-driven displacement, institutional coordination is not a secondary variable.
For investors and supply chain managers tracking critical mineral exposure, the Ituri outbreak signal is not a copper or cobalt risk. It is a tantalum and tin risk, concentrated in a geography where compounding disruption has become a structural condition rather than an episodic event. The difference between Rubaya in January 2025 and Rubaya in June 2026 is the accumulation of stressors: M23 control, the January landslide, the Ebola outbreak, and the backdrop of constitutional uncertainty in Kinshasa. No single one of these events would be sufficient to create sustained supply disruption. Their combination, operating on a site that already supplies 15% of global coltan and sits in a province with limited healthcare infrastructure and active armed group presence, is a different order of risk.
