- DR Congo rare earth potential remains largely unexploited: the country hosts unexplored monazite and carbonatite occurrences but has no operating rare earth mine, unlike its dominant position in cobalt and coltan.
- The Democratic Republic of Congo produced an estimated 72-76% of the world’s mined cobalt in 2024-2025 and holds roughly 6 million tonnes of reserves, more than half the global total, according to the US Geological Survey.
- M23 rebels have controlled the Rubaya coltan mine, a source of 15-30% of global coltan supply, since April 2024, despite a Washington-brokered peace framework signed in December 2025.
- Kinshasa imposed its fourth copper and cobalt concentrate export ban since 2013 in June 2026, tightening the ARECOMS quota system introduced the previous year.
- KoBold Metals confirmed seven exploration permits across Manono and Malemba Nkulu in August 2026, and Virtus Minerals has taken over Chemaf’s Mutoshi and Etoile copper-cobalt mines in a deal exceeding $700 million.
The Democratic Republic of Congo produces almost none of the seventeen elements formally classed as rare earths, yet it sits at the centre of the same supply chain fight. Its wealth lies in cobalt, coltan (refined into tantalum), copper and lithium: minerals grouped with rare earths under the broader “critical minerals” label because Western industry and defence planners depend on them and cannot easily source them elsewhere. Understanding DR Congo rare earth exposure means separating what the country actually mines from what it might one day mine, and pricing both against a conflict that has not gone away.
DR Congo Rare Earth Deposits: Cobalt, Coltan and an Unmined Lanthanide Base
DRC cobalt output reached an estimated 72% of global mine production in 2025 and is forecast to grow further in 2026, driven by Glencore’s Mutanda operation and the newly ramped Musonoi underground project, a Jinchuan Group and Gecamines joint venture. The country also supplies a large share of the world’s coltan, concentrated in North and South Kivu, and ranks among the top copper producers globally. None of this is classical rare earth mining. Actual lanthanide-bearing deposits, monazite associated with carbonatite intrusions and pegmatites in Katanga and the eastern provinces, have been documented since at least the 1960s but remain unquantified at reserve level and unexploited at commercial scale.
That gap is the real story behind the “untapped potential” framing this topic usually gets. USGS Mineral Commodity Summaries data confirms the DRC’s scale in cobalt and copper resources but records no meaningful rare earth reserve figure for the country, a gap shared with most of the carbonatite-hosted deposits identified across central Africa. For now, DR Congo rare earth supply exists only as exploration-stage geology layered on top of an already dominant critical minerals base.
Risk: Conflict, Export Controls and Legal Disputes
Eastern DRC remains the binding constraint on any expansion story. M23, backed by Rwanda according to UN and US assessments, has held the Rubaya coltan hub since April 2024 and continued to tax its output after the June 2025 Washington peace accord and a parallel Doha ceasefire framework with Kinshasa. The US Treasury sanctioned Rwandan military officials in March 2026 for violating the accord, and civil society groups in the region describe the ceasefire as routinely tested rather than enforced. Companies operating in or near the conflict zone, including Alphamin at its Bisie tin mine, have had to weigh renewed fighting risk against US diplomatic backing. This is the same governance risk that shapes investment decisions across Africa’s rare earth and critical minerals project pipeline, but it is sharper in the DRC than almost anywhere else on the continent.
Policy risk compounds the security picture. Kinshasa’s ARECOMS authority, established in 2024, now runs a quota system across cobalt, coltan and lithium exports, with unused monthly allocations reverting to a state-controlled strategic reserve. A June 2026 ordinance banning copper and cobalt concentrate exports outright, the fourth such ban since 2013, forces buyers toward processed oxide and hydroxide material and raises the cost of doing business for anyone without local refining capacity. Layered on top of that, the disputed Manono lithium project remains under arbitration between the DRC government and Australia’s AVZ Minerals at the International Centre for Settlement of Investment Disputes, a dispute KoBold Metals’ own permits are contingent on resolving.
Untapped Potential: The Western Push to De-Risk From China
What has changed in 2026 is the volume of Western capital willing to accept that risk. KoBold Metals, backed by Bill Gates and Jeff Bezos, had its seven exploration permits at Manono and Malemba Nkulu confirmed by the Congolese mining cadastre on 27 August 2026, targeting lithium alongside coltan and tin. Separately, Virtus Minerals has acquired Chemaf’s Etoile mine in Lubumbashi and Mutoshi deposit in Kolwezi, backed by roughly $475 million in debt financing from Orion Resource Partners and support from the US International Development Finance Corporation, targeting a combined 75,000 tonnes of copper and up to 25,000 tonnes of cobalt a year once both plants reach full production. Kinshasa’s own vetted shortlist of investment-ready projects handed to Washington in January 2026 runs well beyond these two deals, spanning manganese, gold and germanium licences alongside cobalt and lithium.
Both deals sit inside the wider US-DRC minerals framework signed alongside the December 2025 peace accord. The strategy mirrors the broader rare earth supply chain shift away from Chinese-controlled processing that is reshaping sourcing decisions well beyond the DRC, and it depends on the Lobito Corridor rail link through Angola to move landlocked output to Atlantic ports. None of it resolves the conflict in the east, and the value of DR Congo rare earth and critical mineral exposure for investors now depends less on geology than on whether Washington’s diplomatic leverage over Kigali outlasts its commercial interest in Kinshasa’s mines.
Does the DRC actually produce rare earth elements?
No, not at commercial scale. The DRC’s mineral wealth is concentrated in cobalt, coltan, copper and lithium. Documented rare earth (monazite) occurrences exist in carbonatite and pegmatite formations, but none has reached production, and reserve estimates aren’t published by USGS or national surveys.
What share of global cobalt supply comes from the DRC?
The DRC is the world’s largest cobalt producer by a wide margin and holds the largest reserve base of any country. Current production and reserve figures are published annually by the US Geological Survey.
Who controls the Rubaya coltan mine?
Rubaya, one of the world’s largest coltan sources, has been under the control of the M23 armed group since 2024. Control has continued despite peace negotiations between the DRC, Rwanda and M23, and remains a central point of dispute in those talks.
What export restrictions apply to DRC copper and cobalt?
The DRC operates a quota and licensing system through its ARECOMS regulator covering cobalt, coltan and lithium, and has periodically banned unprocessed concentrate exports outright to push value-add processing onshore. Current rules should be checked against ARECOMS’ latest notices, as this framework has changed several times.
Which companies are leading Western investment in DRC mining?
KoBold Metals and Virtus Minerals are the two most prominent US-backed entrants, targeting lithium exploration at Manono and copper-cobalt production at Chemaf’s former Kolwezi and Lubumbashi assets respectively, both under the broader US-DRC critical minerals cooperation framework.
