Retrospective on DRC Mining Week 2026

By Dr Nicolaas C Steenkamp  

The conclusion of the 2026 DRC Mining Week at the Pullman Lubumbashi Grand Karavia Hotel, which celebrated its 21st anniversary as the primary convening platform for the Central African Copperbelt, marked a definitive pivot for the Democratic Republic of Congo (DRC).

For the last two decades, the narrative surrounding the Katanga region’s mineral wealth has fluctuated between talk of geological endowment and infrastructure deficits, regulatory-opaque zones, and structural bottlenecks. The overarching theme of the 2026 edition was a clear call to action: moving beyond raw extraction toward localised industrialisation, hard-engineered infrastructure solutions, and cross-border value chain development.

As the global energy transition intensifies its focus on critical minerals, the DRC finds itself in a high-pressure environment. It produces over 70% of the world’s cobalt and stands firmly as Africa’s largest copper producer. Yet, the pressure from national leadership and regional actors is mounting to move away from the model of dig-and-ship. The conversations this year were not about if the DRC should beneficiate its minerals locally, but how the practicalities of power, logistics and technology can make it happen now.

In-country beneficiation

From a geological and geometallurgical perspective, the DRC’s Copperbelt remains one of the most phenomenal mineral provinces on earth. The high-grade stratiform sediment-hosted copper-cobalt deposits of the Central African Copperbelt are structurally unique. However, processing these complex ores into higher-value products locally requires a massive leap in technical sophistication and, crucially, a stable processing environment.

During the mineral processing and value-chain development sessions, a recurring theme was the transition from exporting raw concentrates to producing high-purity cathodes and precursors for the battery market. The DRC has repeatedly signalled its intention to enforce stricter export controls on unrefined minerals to drive local industrialisation.

However, local beneficiation is entirely dependent on the availability of two main operational inputs: reagents and reliable power. The discussion focused heavily on the expansion of hydro-metallurgical and pyrometallurgical capacity within the Katanga province. Major operators highlighted that while the geological grades justify advanced refining investments, the local chemical supply chains, specifically the bulk importation of sulfuric acid and sulfur required for leaching oxidised copper-cobalt ores, remain a costly logistical nightmare. The consensus among technical experts is that for true localised value-chain integration to occur, regional chemical manufacturing plants must be co-developed alongside mining operations.

Furthermore, the physical characteristics of deeper, primary sulfide ores currently being encountered by ageing open-pit operations transitioning to underground mines require different processing circuits than the near-surface oxide ores. This geological transition demands significant capital expenditure to upgrade concentrators and flotation circuits. It is a classic geometallurgical challenge: the block models are shifting, and the processing plants must shift with them.

The energy bottleneck

The operational realities of the DRC mining sector are fundamentally constrained by the capacity of the national energy sector. The 2026 conference sessions dedicated to energy solutions highlighted a distinct shift in how mining houses are approaching this deficit. The era of relying solely on the promise of mega-hydro projects like Grand Inga is being replaced by immediate, decentralised, and hybrid power strategies.

Mining operations across the Copperbelt are currently operating under continuous power rationing, forcing heavy reliance on expensive diesel generation back-ups, which drastically inflates the All-In Sustaining Costs (AISC) per pound of copper produced.

To mitigate this, the trend in 2026 is the aggressive rollout of localised solar photovoltaic (PV) arrays paired with utility-scale battery energy storage systems (BESS), alongside private-public partnerships (PPPs) aimed at refurbishing existing domestic run-of-river hydro stations. Several majors shared case studies of newly commissioned micro-grids that blend solar, hydro, and diesel to ensure the continuous operation of high-demand automated processing plants.

There was also significant discussion regarding cross-border power wheeling arrangements. The Southern African Power Pool (SAPP) remains a vital mechanism, with mining houses increasingly looking to import power from neighbouring Zambia or even further south, despite the regional transmission lines being severely constrained. The technical consensus is clear: if the DRC is to successfully mandate local smelting and refining of copper and cobalt, the region requires an immediate injection of reliable, baseload electricity. Without it, refining mandates will simply result in stockpiled concentrates and halted production lines.

Logistics and the Lobito Corridor

For years, the export of DRC minerals followed a long southern route via the North-South Corridor to South African ports like Durban, or eastwards to Dar es Salaam in Tanzania and Beira in Mozambique. These traditional routes are notorious for border delays, customs inefficiencies, and deteriorating road infrastructure, adding weeks to transit times and exposing high-value copper cathodes to significant security risks en route.

The standout logistical talking point of DRC Mining Week 2026 was the operational acceleration of the Lobito Atlantic Railway Corridor. Connecting the heartland of the Kolwezi mining district directly to the deep-water port of Lobito in Angola, this western-facing rail corridor is a potential game-changer for the region’s economics.

The geopolitical backing of the Lobito Corridor, driven heavily by funding commitments from the United States and the European Union as they look to secure stable supply chains for critical minerals, has translated into visible, rapid rail track upgrades and port infrastructure expansions.

The mining houses operating around Kolwezi and Lubumbashi expressed immense optimism regarding the trial mineral trains that ran throughout late 2025 and early 2026. Shifting bulk freight from road to rail not only drops logistics costs drastically but significantly reduces the carbon footprint of the exported product, an increasingly critical metric for European and North American buyers bound by strict Scope 3 emission regulations.

However, delegates cautioned that the success of the Lobito Corridor hinges entirely on long-term regional co-operation and the elimination of bureaucratic red tape at the Luau-Dilolo border post between Angola and the DRC.

Responsible sourcing

The international footprint at DRC Mining Week 2026 was broader and more diverse than before. The exhibition floors hosted country pavilions representing China, the United Kingdom, India, Germany, the Netherlands and Sweden. The prominent presence of Middle Eastern capital, particularly from the United Arab Emirates and Saudi Arabia, underscored the shifting dynamics of global mineral procurement.

The DRC finds itself squarely in the middle of a geopolitical tug-of-war. Chinese companies, through massive joint ventures like Sicomines and major independent assets owned by the likes of Zijin Mining and CMOC, continue to dominate the physical extraction and processing landscape of the Copperbelt. Concurrently, Western nations are attempting to claw back influence by leveraging strict Environmental, Social, and Governance (ESG) frameworks and offering transparent financing mechanisms to local partners.

The industry is facing scrutiny regarding the traceability of cobalt. The formal mining houses spent considerable time demonstrating their advanced supply chain tracking technologies, including blockchain-verified digital passports for minerals, designed to assure international end-users that their product is entirely free from human rights abuses or child labour.

A major point of clarity raised during these sessions was the ongoing challenge of integrating or separating the Artisanal and Small-Scale Mining (ASM) sector from large-scale industrial operations. The ASM sector remains a vital livelihood for hundreds of thousands of Congolese citizens and accounts for a fluid percentage of the country’s cobalt output. The discussion moved away from the goal of eliminating ASM, focusing instead on formalisation schemes, such as designated artisanal mining zones (ZEAs) and state-backed purchasing co-operatives like the Entreprise Générale du Cobalt (EGC). The consensus is clear: international Western markets will no longer accept unverified cobalt, and large-scale miners must actively collaborate with local communities and regulators to create ring-fenced, ethical supply ecosystems.

Technological advancements

As shallow oxide reserves face depletion, the DRC is steadily preparing for a shift toward massive underground mining operations. This transition requires a technological leap forward. Global Original Equipment Manufacturers (OEMs) and engineering providers showcased cutting-edge solutions tailored for the Copperbelt’s unique conditions. There was a notable emphasis on Battery Electric Vehicles (BEVs) for underground fleets, replacing diesel-powered haulage with electric equipment to dramatically reduce ventilation shaft requirements and operational heat buildup at depth. Advanced mineral processing technology, such as high-efficiency flotation cells and automated sorting systems designed to optimise grade recovery from complex, variable ore bodies. Digitalisation and real-time data analytics, incorporating telemetry and sensor arrays across mining fleets and processing circuits to streamline predictive maintenance in remote operating environments.

The barrier to adopting these technologies in the DRC has never been a lack of corporate will, it is the availability of a skilled local workforce capable of operating and maintaining advanced digital and automated systems. This highlights the urgent need for structural investment in vocational training, mining engineering academies, and geometallurgical research facilities within the DRC. The industry must move beyond bringing in external expats for technical roles, ensuring that the local workforce is actively upskilled to run the mines of the future.

Conclusion

The 2026 DRC Mining Week served as a diagnostic tool for the health of the African Copperbelt. It proved that the DRC is no longer just a frontier exploration destination, it is an industrialising mining heavyweight navigating complex, mature operational challenges.

The transition from a “potential” narrative to a practical, implementation-driven reality is well underway. The geological wealth of the Copperbelt region is undisputed, but its long-term economic stability relies on solving the physical challenges of power generation, rail logistics, localised processing metallurgy, and ethical supply chain validation.

If the collaborative spirit, regional alignment, and infrastructure investments showcased in Lubumbashi this past June can maintain their momentum, the DRC will successfully transform its immense geological endowment into lasting, diversified economic growth. The tracks are laid, the strategy is defined, and the industry is moving forward.
