The Company State
Union Minière du Haut-Katanga, established in 1906 as a joint venture between the Comité Spécial du Katanga and the Belgian Société Générale banking group, became one of the most powerful companies in African history. At its peak, Union Minière produced over 60 percent of the Western world's cobalt, 6-8 percent of global copper, and significant quantities of uranium, zinc, germanium, and other minerals. The company's annual revenue exceeded the total budget of the Belgian colonial state.
Union Minière's operations centred on the towns that define the Lobito Corridor's mineral heartland today: Lubumbashi (then Elisabethville), Likasi (then Jadotville), and Kolwezi. The company built these towns. It constructed worker housing, hospitals, schools, sports facilities, and churches. It operated power stations, water systems, and road networks. It controlled economic life to a degree that made the distinction between company and government largely meaningless.
This corporate sovereignty had benefits for workers within the system: Union Minière's worker towns provided standards of housing, healthcare, and education that exceeded what the colonial state provided elsewhere. But it also created total dependency: workers who lost their employment lost not only their income but their housing, their healthcare, their children's schooling, and their community. The company's paternalism was inseparable from its control.
Wartime Significance: Uranium and the Bomb
In 1942, a shipment of uranium ore from Union Minière's Shinkolobwe mine in Katanga arrived at a warehouse in New York. This Congolese uranium would be refined and enriched to produce the fissile material for the atomic bombs dropped on Hiroshima and Nagasaki in 1945. The Manhattan Project's dependence on Congolese uranium illustrates a pattern that the corridor perpetuates: African mineral resources with global strategic significance, extracted under conditions that African communities do not control and from which they derive minimal benefit.
The strategic significance of Katanga's minerals — then uranium, now cobalt and germanium — has consistently attracted great power interest while communities at the mine face remain impoverished. The Lobito Corridor's framing as "supply chain security for the energy transition" echoes the wartime rhetoric of "strategic materials for national security." The question then and now is whether strategic significance translates into community benefit.
Forced Labour and Worker Exploitation
Union Minière's workforce was recruited, often coercively, from across the Congo and neighbouring territories. During the early decades, forced labour recruitment through the colonial state's tax and conscription systems provided workers. Conditions were brutal: mining operations in the 1920s and 1930s involved manual labour in open pits and underground workings with minimal safety equipment. Worker mortality rates were high.
The company's labour practices evolved over time. Post-World War II, Union Minière adopted a "stabilisation" policy — encouraging permanent settlement of workers and their families in company towns rather than relying on migrant labour. This shift improved worker welfare but deepened dependency. Workers who spent their entire careers in company towns had no alternative economic base when those towns eventually deteriorated.
Independence, Secession, and Nationalisation
When Congo achieved independence in 1960, Union Minière and Belgian interests supported the secession of Katanga province under Moïse Tshombe — a move designed to keep the mineral-rich province under effectively Belgian control. The Katanga secession, the assassination of Prime Minister Patrice Lumumba, and the subsequent political turbulence established patterns of resource-linked political conflict that continue to shape DRC politics.
In 1967, President Mobutu Sese Seko nationalised Union Minière's Congolese operations, creating Gécamines (Générale des Carrières et des Mines). Mobutu's nationalisation was popular domestically but proved economically devastating over the following decades, as detailed in our companion article.
The Legacy for the Lobito Corridor
Union Minière's legacy shapes the corridor in three ways that our monitoring must acknowledge. First, the physical infrastructure — mines, processing facilities, towns, transport networks — that corridor investment builds upon was created during the colonial period under conditions of exploitation. Second, the communities that live along the corridor carry institutional memories of corporate sovereignty that inform their distrust of mining companies, foreign investors, and promises of benefit-sharing. Third, the environmental legacy of a century of inadequately regulated mining — contaminated water, degraded land, toxic waste — creates baseline conditions that new investment must remediate rather than compound.
Understanding Union Minière is not an exercise in historical blame. It is essential context for understanding why communities in Kolwezi and Likasi respond to corridor development with scepticism rather than celebration. They have seen this before. Their scepticism is earned. Overcoming it requires demonstrable commitment to doing things differently — commitment that our monitoring independently verifies.
Legacy for the Modern Corridor
The historical patterns documented in this account of union miniere katanga continue to shape corridor development in ways that contemporary analysis frequently underestimates. Decision-makers — investors, government officials, international organisations — approach the corridor as a forward-looking infrastructure project. Communities along the corridor approach it as the latest chapter in a long history of external actors extracting value from their region. This divergence in perspective explains many of the tensions that our monitoring documents.
The institutional legacies of union miniere katanga persist in governance structures, land tenure arrangements, community expectations, and political dynamics that corridor investors encounter. Colonial-era concession frameworks shaped post-independence mining codes. War-era displacement patterns created community configurations that current development plans must navigate. Privatisation-era experiences shaped community attitudes toward foreign investment. These historical layers cannot be wished away by development rhetoric; they must be understood, acknowledged, and addressed.
For our monitoring and advocacy work, this history provides essential context for assessing current practices. When we evaluate displacement procedures, we assess them against historical patterns of displacement that communities remember. When we evaluate benefit-sharing proposals, we compare them to historical patterns of benefit extraction that communities have experienced. When we evaluate community consultation processes, we measure them against historical patterns of exclusion that communities have endured. History is not background; it is the lens through which communities evaluate the corridor's promises.
The corridor has the potential to break historical patterns of extraction without community benefit. But realising this potential requires conscious effort to design governance frameworks, community engagement processes, and benefit-sharing mechanisms that explicitly address historical grievances. Our role is to ensure that this historical consciousness informs corridor development — that the mistakes documented in these historical accounts are not repeated in the next chapter of the corridor's story.

The Company-State
Union Minière du Haut Katanga operated as a virtual state within a state, controlling not just mining operations but the entire social infrastructure of the Katanga mining region. The company built and maintained housing, hospitals, schools, recreational facilities, and commercial centres for its workforce. It operated its own police force, administered its own justice system for labour disputes, and maintained a comprehensive social welfare system that extended from cradle to grave.
This paternalistic model — comprehensive social provision in exchange for labour compliance — created a workforce that was simultaneously well-provided-for by colonial standards and entirely dependent on the company. Workers who challenged company authority or labour conditions faced not just dismissal but loss of housing, healthcare, education for their children, and access to the entire social infrastructure that Union Minière controlled.
The model's legacy shapes community expectations today. Residents of Kolwezi, Likasi, and Lubumbashi remember — directly or through family memory — when the mining company provided everything. They compare today's situation, where mining companies extract enormous wealth while community infrastructure crumbles, to the Union Minière era when at least the company maintained roads, hospitals, and schools. This comparison is not nostalgia for colonialism; it is a demand that today's mining companies match or exceed the social provision that a colonial company delivered generations ago.
For corridor investors, the Union Minière precedent sets an implicit benchmark. Communities do not merely expect employment; they expect comprehensive social investment. Copper and cobalt prices generate billions in revenue; communities expect visible returns in infrastructure, services, and opportunity. Our ESG assessments incorporate this historical expectation into community relations evaluation.
Wartime Production and the Manhattan Project
Union Minière's Shinkolobwe mine produced the uranium used in the atomic bombs dropped on Hiroshima and Nagasaki. This extraordinary fact — that Congolese mining directly enabled the most destructive weapons in human history — illustrates the global strategic significance of Katanga's minerals and the exploitation of Congolese resources for purposes entirely disconnected from Congolese interests.
During World War II, Union Minière supplied over 80% of the uranium used in the Manhattan Project. Congolese miners extracted the ore that ended the war and launched the nuclear age, receiving no recognition, no compensation, and no protection from the radioactive materials they handled. Shinkolobwe's miners suffered elevated cancer rates and premature death — costs borne by Congolese bodies for weapons deployed on the other side of the world.
This history resonates with contemporary concerns about critical mineral supply chains. Today's cobalt miners extract materials that power smartphones and electric vehicles used globally, while bearing the health risks, environmental damage, and community disruption that extraction generates. The parallel between uranium for atomic bombs and cobalt for Tesla batteries is not exact, but the structural pattern — African minerals serving global purposes while African communities bear the costs — persists.
Our documentation mandate includes ensuring that this pattern is identified, quantified, and challenged. When corridor minerals enable the global energy transition, the communities that host extraction must share in the benefits, not merely bear the costs. This is not radical politics; it is the minimum standard of justice that the uranium precedent demands.
