DRC Conflict Minerals

Overview

The term "conflict minerals" refers to minerals whose extraction and trade finances armed conflict and human rights abuses. In the DRC context, the term is most commonly applied to four minerals — tin (cassiterite), tantalum (coltan), tungsten (wolframite), and gold, collectively known as "3TG" — that are mined primarily in the eastern provinces and whose trade has been linked to the activities of armed groups operating in one of the world's most protracted humanitarian crises.

The conflict minerals issue is geographically and contextually distinct from the copper-cobalt mining sector of the southern Copperbelt that drives the Lobito Corridor. The eastern DRC, where conflict minerals are principally sourced, is separated from the Copperbelt by hundreds of kilometres of territory and by fundamentally different security, governance, and economic conditions. This geographic distinction is important for understanding both the DRC's mining sector and the specific dynamics of the Lobito Corridor — but it does not mean the issues are unconnected. Regulatory frameworks developed to address conflict minerals in the east have influenced due diligence requirements applied to all DRC minerals, including cobalt and copper from the south.

Eastern DRC Context

The eastern provinces of the DRC — principally North Kivu, South Kivu, Ituri, and parts of Maniema and Tanganyika — have experienced continuous armed conflict since the mid-1990s. The roots of the conflict lie in the 1994 Rwandan genocide and its aftermath, which displaced millions and triggered the two Congo Wars (1996-1997 and 1998-2003). Although the wars formally ended, armed violence has persisted in the east for over two decades, perpetuated by a complex ecosystem of domestic and foreign armed groups, ethnic militias, and the Congolese state's own security forces.

As of 2025, the eastern DRC conflict has intensified with the resurgence of the M23 rebel group, widely documented as receiving support from Rwanda. M23's advances into North Kivu, including the capture of the provincial capital Goma in early 2025, have displaced millions of civilians and further destabilised the region. The conflict has drawn in regional military forces (Rwandan and Burundian troops are present on DRC soil) and international mediation efforts, with limited success.

Mineral resources play a role in the conflict economy, but the relationship is more complex than the simple narrative of "minerals funding warlords" that dominated early discussions. Armed groups derive revenue from mineral taxation (imposing levies on miners, traders, and transport at checkpoints), from direct control of mining sites, and from broader extortion of economic activity in areas they control. However, minerals are one of several revenue sources for armed groups, alongside agricultural taxation, logging, charcoal, smuggling, and external financing from state sponsors.

3TG Minerals

The four minerals designated as conflict minerals — tin, tantalum, tungsten, and gold — are mined predominantly through artisanal methods in the eastern DRC.

Tantalum (derived from coltan — colombo-tantalite) has been the most high-profile of the DRC's conflict minerals, owing to its critical role in electronic capacitors and its association with the "coltan rush" of the early 2000s that drew global attention to the link between consumer electronics and armed conflict. The DRC holds some of the world's largest tantalum reserves, and the mineral's high value-to-weight ratio makes it particularly attractive for artisanal mining and particularly susceptible to diversion through conflict-linked supply chains.

Gold is arguably the most problematic conflict mineral in practice. Unlike tin, tantalum, and tungsten, which pass through identifiable smelters that can be audited, gold can be easily melted, alloyed, and sold through opaque trading networks. A significant proportion of artisanally mined gold from eastern DRC is believed to be smuggled through neighbouring countries — principally Uganda, Rwanda, and Burundi — without any conflict-free certification.

Armed Groups & Mining

Dozens of armed groups operate in eastern DRC, many of them deriving at least partial revenue from mineral extraction and trade. The relationship between armed groups and mining takes several forms.

Direct control of mining sites occurs where an armed group physically controls a mine and either forces local populations to mine on its behalf or collects a substantial share of production as taxation. This model has been documented at numerous sites in North Kivu and South Kivu, particularly for gold and coltan. Checkpoint taxation is more widespread — armed groups establish roadblocks along transport routes and demand payment from traders moving minerals from mine sites to trading centres. This model does not require direct control of mining sites but effectively imposes a conflict tax on the entire mineral supply chain in areas where armed groups operate.

Complicity of state security forces is a complicating factor. Elements of the Congolese military (FARDC) and police have been documented engaging in the same extractive practices as non-state armed groups — controlling mining sites, imposing illegal taxes, and profiting from mineral trade. This blurs the distinction between "conflict" and "legitimate" mineral supply chains and complicates regulatory approaches that assume a clear line between conflict-affected and conflict-free sources.

Regulatory Framework

The DRC conflict minerals problem has generated a substantial international regulatory response, driven primarily by advocacy campaigns that linked consumer products (particularly smartphones) to armed conflict and human rights abuses.

US Dodd-Frank Act Section 1502 (2010)

Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act required US-listed companies to disclose whether their products contained conflict minerals originating from the DRC or adjoining countries, and if so, to conduct due diligence on their supply chains. This provision, while not constituting a ban on DRC minerals, created significant compliance pressure on companies to demonstrate that their supply chains were conflict-free.

EU Conflict Minerals Regulation (2021)

The EU Conflict Minerals Regulation, which came into effect in January 2021, requires EU importers of tin, tantalum, tungsten, and gold above specified volume thresholds to conduct supply chain due diligence in line with the OECD Due Diligence Guidance. Unlike the Dodd-Frank disclosure approach, the EU regulation imposes mandatory due diligence obligations on importers, requiring them to identify and mitigate risks of conflict financing and human rights abuses in their supply chains.

OECD Due Diligence Guidance

The OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas provides the international standard for mineral supply chain due diligence. Published in 2011, the guidance establishes a five-step framework for identifying, assessing, and mitigating supply chain risks. It is referenced by both US and EU legislation and has been adopted by industry programmes including the Responsible Minerals Initiative (RMI) and ITSCI.

Geographic Distinction from the Copperbelt

A critical analytical point, frequently misunderstood in public discussion, is the geographic and contextual distinction between the conflict minerals of eastern DRC and the copper-cobalt mining of the southern Copperbelt.

Eastern DRC (North Kivu, South Kivu, Ituri) and the Copperbelt (Lualaba, Haut-Katanga) are separated by approximately 1,000 to 1,500 kilometres. The conflict dynamics of the east — armed group activity, displacement, ethnic violence — are essentially absent from the Copperbelt mining provinces. The minerals are different (3TG in the east versus copper-cobalt in the south), the mining methods are different (though artisanal mining is present in both regions), and the security environment is different.

However, the regulatory frameworks developed in response to eastern DRC conflict minerals have spilled over into the Copperbelt context. Companies sourcing cobalt from the DRC face due diligence expectations shaped by the conflict minerals framework, even though cobalt is not a designated conflict mineral under either US or EU law. the platform between "DRC" and "conflict minerals" in public perception creates reputational risks for all DRC mineral supply chains, including the copper and cobalt that flow through the Lobito Corridor.

Cobalt from the southern Copperbelt faces its own human rights concerns — primarily child labour and dangerous working conditions in artisanal mining — but these are distinct from the armed-conflict-related concerns that define the conflict minerals framework. Conflating the two undermines both accurate analysis and effective policy response.

Due Diligence & Compliance

Due diligence programmes for DRC minerals have evolved significantly since the early regulatory responses to conflict minerals. The most established programmes include:

The ITSCI (International Tin Supply Chain Initiative) provides mine-site-level traceability for tin and tantalum through a tag-and-bag system that tracks mineral lots from mine to export. ITSCI covers hundreds of mine sites in eastern DRC and neighbouring countries, and its tags are the primary mechanism through which downstream companies demonstrate that their tin and tantalum supply chains meet conflict-free requirements.

The Responsible Minerals Initiative (RMI) operates the Responsible Minerals Assurance Process (RMAP), which audits smelters and refiners to verify that they source minerals responsibly. RMI-audited smelters serve as bottlenecks in the mineral supply chain where conflict-free status can be verified.

For cobalt specifically, the Fair Cobalt Alliance, the Cobalt Institute, and various company-specific programmes provide due diligence frameworks focused on the artisanal cobalt supply chain in the Copperbelt. These programmes address child labour, safety, and environmental concerns rather than armed-group financing, reflecting the different risk profile of southern versus eastern DRC mining.

Relevance to the Lobito Corridor

The conflict minerals issue is relevant to the Lobito Corridor in several indirect but important ways. First, the regulatory infrastructure developed in response to conflict minerals — including due diligence requirements, traceability systems, and reporting obligations — shapes the compliance environment for all DRC minerals, including the copper and cobalt that the corridor is designed to transport.

Second, the reputational association between the DRC and conflict minerals creates challenges for the corridor's positioning as a responsible supply chain route. Companies considering the corridor must navigate stakeholder expectations shaped by two decades of conflict minerals advocacy. The corridor's ability to offer documented, traceable mineral transport is a potential competitive advantage in this context.

Third, the ongoing conflict in eastern DRC affects the DRC's overall political stability, governance capacity, and international relationships, all of which indirectly influence the operating environment for the corridor. Government attention and resources diverted to the eastern conflict reduce the capacity available for corridor-related governance, and the diplomatic tensions between the DRC and Rwanda complicate the regional cooperation that the corridor requires.

The geographic separation between the eastern conflict zone and the southern Copperbelt is real and important, but it does not insulate the corridor from the broader consequences of the DRC's conflict minerals challenge. A comprehensive understanding of the corridor's environment requires appreciation of both the distinction and the connection between these two dimensions of DRC mining.
