Mobutu, Nationalisation, and the Decline of Gécamines
President Mobutu Sese Seko's 1967 nationalisation of Union Minière created Gécamines, which initially maintained high production levels reaching nearly 500,000 tonnes of copper annually by the mid-1980s. But Mobutu's kleptocratic regime systematically extracted Gécamines' revenue for personal enrichment and political patronage rather than reinvesting in maintenance, exploration, and technology. Production declined catastrophically from 465,000 tonnes in 1986 to under 20,000 tonnes by 2003.The decline was not merely economic — it was a social catastrophe. Gécamines' company towns in Likasi, Kolwezi, and Lubumbashi, which had provided housing, healthcare, and education for hundreds of thousands, deteriorated as the company collapsed. Workers went unpaid for months. Hospitals closed. Schools deteriorated. Communities that had depended entirely on the company were abandoned.
This collapse created the conditions for today's artisanal mining boom. When Gécamines could no longer employ workers or control its concessions, communities turned to informal mining for survival. The estimated two million artisanal miners in the DRC today are the direct legacy of Gécamines' failure. The artisanal mining crisis that the corridor confronts has its roots in Mobutu's kleptocracy.
Gécamines today survives as a state mining company that participates in joint ventures with foreign investors — Glencore, CMOC, Ivanhoe, and Zijin all hold JVs with Gécamines. The company's role is essentially to provide concession access in exchange for minority stakes. Whether this arrangement delivers adequate value to the Congolese state is a question our ESG monitoring addresses.
Mobutu's Nationalisation
In 1967, Mobutu Sese Seko nationalised Union Minière du Haut Katanga, renaming it Gécamines (Générale des Carrières et des Mines). The nationalisation was part of Mobutu's broader "Zairianisation" programme — the seizure of foreign-owned businesses and their transfer to Congolese (Zairean) ownership. For Gécamines, nationalisation began a decades-long decline from one of the world's largest and most profitable mining companies to a hollowed-out shell.
Initially, nationalisation did not immediately destroy Gécamines. The company retained experienced Belgian technicians through management contracts and continued to operate at near-previous production levels through the early 1970s. Copper production exceeded 400,000 tonnes per year. Cobalt output remained globally significant. Gécamines provided comprehensive social services to its workforce — housing, healthcare, education, and recreation — maintaining the model established by Union Minière.
The Looting of Gécamines
Under Mobutu's kleptocratic regime, Gécamines became a personal revenue source for the president and his political network. Mining revenues that should have funded reinvestment, maintenance, and community services were diverted to Mobutu's personal accounts, political patronage networks, and security apparatus. The systematic extraction of value from Gécamines — what scholars call "state predation" — progressively destroyed the company's productive capacity.
Investment in mine maintenance, equipment renewal, and exploration ceased. Processing plants operated with obsolete equipment. Trained personnel left, replaced by political appointees without technical qualifications. Production declined steadily from the mid-1970s onward: from over 400,000 tonnes of copper in the early 1970s to below 50,000 tonnes by the late 1990s. Gécamines went from producing approximately 6% of global copper to less than 0.5%.
The Kamoto underground mine near Kolwezi collapsed in 1990, killing multiple miners and rendering one of the world's richest copper-cobalt deposits temporarily inaccessible. The collapse symbolised the broader deterioration: decades of deferred maintenance had made mining operations physically dangerous as well as economically unsustainable.
Social Catastrophe
Gécamines' decline was simultaneously a corporate failure and a social catastrophe. The company had functioned as a quasi-state in the Katanga mining region, providing services that the Congolese government did not. Gécamines hospitals served not just employees but surrounding communities. Gécamines schools educated children who had no other options. Gécamines-maintained roads and water systems served entire towns.
As revenue declined and looting intensified, these services collapsed. Hospitals ran out of medicines. Schools lost teachers. Water systems broke down. Housing deteriorated. The communities of Likasi, Kolwezi, and Lubumbashi experienced a regression in living standards that reversed decades of development. Infrastructure built during the colonial and early post-independence periods fell into disrepair.
The workforce that had numbered over 30,000 was progressively reduced through unpaid wages, forced retirement, and abandonment of positions. Workers who remained often went months without salary. The skilled mining workforce that had made Gécamines one of Africa's most technically sophisticated operations dispersed, many leaving the DRC entirely.
The Post-Mobutu Scramble
After Mobutu's overthrow in 1997, the new government under Laurent-Désiré Kabila and subsequently Joseph Kabila sought to revive the mining sector through joint venture partnerships between Gécamines and foreign mining companies. These partnerships — with companies including Glencore, CMOC (then Freeport McMoRan), ERG, and various Chinese companies — gave foreign operators access to Gécamines' mining titles in exchange for investment commitments and revenue sharing.
Many of these partnerships were negotiated under conditions of conflict, political instability, and governance weakness that favoured the foreign companies. A series of contract reviews, most notably by the Carter Center and various government commissions, documented terms that were highly disadvantageous to the DRC. Gécamines retained minority stakes with limited influence over operational decisions, while foreign operators controlled the most valuable mining assets.
Corridor Legacy
Gécamines' decline destroyed the industrial ecosystem that the corridor now seeks to rebuild. The railway infrastructure, processing capacity, technical workforce, and community services that sustained Katanga's mining industry for decades were systematically degraded. Current corridor investment must rebuild not just transport infrastructure but the broader industrial and social ecosystem that makes mining sustainable.
For communities along the corridor, Gécamines' history creates both nostalgia and cynicism. Older residents remember when the company provided good jobs, decent housing, and functioning services. They compare this remembered past — imperfect as it was — to the present, where foreign mining companies generate enormous profits while community infrastructure remains inadequate. This comparison shapes expectations for corridor development: communities demand that new investment deliver the comprehensive social benefits that Gécamines once provided and that its decline destroyed.
Legacy for the Modern Corridor
The historical patterns documented in this account of mobutu gecamines decline 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 mobutu gecamines decline 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 Corruption Mechanics
The mechanics of Gécamines' looting were systematic rather than random. Mobutu and his associates extracted value through multiple channels: direct diversion of mining revenue to personal accounts; sale of mining concessions at below-market prices in exchange for kickbacks; procurement fraud that channelled equipment and supply contracts to politically-connected companies at inflated prices; and employment of political allies in senior management positions regardless of qualifications.
International enablers — banks, commodity traders, and governments — facilitated the looting. Swiss banks held Mobutu's stolen wealth. Belgian companies continued to operate in partnership with a regime whose corruption was well-documented. Western governments provided diplomatic support and development assistance that indirectly enabled continued theft. The DRC's mineral wealth was extracted through a system of corruption that extended far beyond Congolese borders.
This history of internationally-enabled corruption informs current governance requirements for corridor investment. The EU Corporate Sustainability Due Diligence Directive, anti-money laundering regulations, and enhanced transparency requirements all aim to prevent repetition of the patterns that destroyed Gécamines. Our monitoring verifies whether these requirements translate into practice — or whether new forms of corruption exploit gaps in the regulatory framework.
