As 400 artisanal miners lie dead in Rubaya's collapsed tunnels, the US and China race to control the DRC's critical mineral wealth — and the future of technology itself
Executive Summary
- The January 28 Rubaya mine collapse that killed 400+ people — including children — exposes the human cost of the world's insatiable demand for coltan, cobalt, and copper, minerals essential to every smartphone, EV battery, and AI data center on Earth.
- The US is mounting its most aggressive challenge to China's mineral dominance in a generation: a $9 billion Glencore deal, Project Vault's $12 billion strategic stockpile, and the first-ever Critical Minerals Ministerial in Washington signal a fundamental shift.
- China controls 80% of Congo's mining output and 40% of global cobalt through a single company (CMOC) — but Chinese analysts are now warning of "structural deficiency" for the first time, as Washington's resource diplomacy begins to bite.
Chapter 1: The Rubaya Catastrophe — A Microcosm of the Resource Curse
On January 28, 2026, heavy rains triggered a series of landslides at the Rubaya mining complex in North Kivu, eastern Democratic Republic of Congo. Hand-dug tunnels — some over-mined for years without any maintenance or safety oversight — collapsed in sequence, burying hundreds of artisanal miners alive. By February 2, the confirmed death toll had surpassed 400, making it one of the deadliest mining disasters in African history.
The victims were not employees of multinational corporations. They were artisanal miners — men, women, and children — working with picks and shovels in tunnels where up to 500 people crowded into a single pit. Many died of asphyxiation. Others were crushed by collapsing earth. Around 20 survivors were evacuated to hospitals in Goma, the nearest major city, itself under siege from the M23 rebel group that has controlled the Rubaya mines since May 2024.
The Rubaya mines supply over 15% of the world's tantalum (refined from coltan), a mineral without which no smartphone, laptop, or surgical implant can function. M23 rebels tax the coltan trade at over $800,000 per month, funding an insurgency that has displaced millions across eastern Congo. The mines reopened within days of the collapse — the global supply chain does not pause for funerals.
This is the resource curse in its most distilled form: a country sitting atop an estimated $24 trillion in mineral wealth, where the average citizen earns less than $1.50 per day, where armed groups and foreign corporations extract value while communities bear the cost in blood.
Chapter 2: The Great Mineral Scramble — America Strikes Back
For nearly two decades, China methodically built an unassailable position in Congo's mining sector. By 2025, Chinese firms controlled approximately 80% of the DRC's mining output. The crown jewel is China Molybdenum Company (CMOC), which operates the Tenke Fungurume and Kisanfu mines — together producing roughly 40% of the world's cobalt supply.
But in February 2026, the United States is mounting the most aggressive challenge to China's mineral dominance since the rare earth crisis of 2010.
The Glencore-Orion Deal ($9 Billion)
On February 3, Swiss commodities giant Glencore announced a non-binding Memorandum of Understanding to sell a 40% stake in its DRC copper and cobalt operations to the Orion Critical Mineral Consortium (Orion CMC). The deal values the assets at approximately $9 billion including debt. Orion CMC is not an ordinary private equity vehicle — it is led by Orion Resource Partners with sovereign backing from:
- US International Development Finance Corporation (DFC) — the US government's development finance arm
- ADQ — Abu Dhabi's sovereign wealth fund
This structure mirrors the "resources-for-security" model that Washington has increasingly deployed across Africa: American government capital, Gulf sovereign wealth, and private mining expertise, aligned to counter Chinese incumbency.
Project Vault ($12 Billion Strategic Stockpile)
The Trump administration's Project Vault initiative aims to create a $12 billion strategic stockpile of critical minerals. Under this program, Canada's Ivanhoe Mines and Congo's state-owned Gécamines are in advanced discussions to ship high-grade zinc, copper, and cobalt concentrates directly to the United States — bypassing Chinese processing entirely.
The Critical Minerals Ministerial
On February 5, Secretary of State Marco Rubio hosted the inaugural Critical Minerals Ministerial in Washington, bringing together delegations from 50 countries including the DRC. The message was unmistakable: the US intends to build parallel supply chains that reduce dependence on Chinese refining and processing.
| Metric | China's Position | US Response |
|---|---|---|
| DRC mining output control | ~80% | Glencore-Orion $9B deal |
| Global cobalt share (CMOC alone) | ~40% | Project Vault stockpile |
| Cobalt refining capacity | ~75% global | Critical Minerals Ministerial |
| Processing infrastructure | Decades of investment | DFC + Gulf sovereign backing |
Chapter 3: The Stakeholders — Who Wins, Who Loses
The DRC Government (Felix Tshisekedi)
President Tshisekedi has positioned himself as the indispensable partner. Last year, the DRC signed a strategic partnership agreement with Washington, effectively promising access to critical mineral sites in exchange for security guarantees. Trump himself claimed credit: "I actually stopped the war with Congo and Rwanda. And they said to me, 'Please, please, we would love you to come and take our minerals.'"
But Tshisekedi faces a credibility problem. The DRC's mining code theoretically gives the state a 20% stake in major operations, but enforcement is weak, corruption is endemic, and the eastern provinces where the richest deposits lie are effectively outside government control. The $24 trillion in estimated mineral wealth has not translated into development: the DRC ranks 179th out of 191 countries on the Human Development Index.
China — The Incumbent Under Threat
Chinese analysts are sounding alarms not heard before. Xiao Wenhao of the Shanghai Metals Market warned that US-DRC deals could create a "structural deficiency" in China's cobalt supply chains. The recommended response is diversification — particularly accelerating cobalt production in Indonesia, where Chinese firms already dominate nickel processing.
But Indonesia is not Congo. Indonesian cobalt is a byproduct of nickel laterite processing, yielding lower-grade material at higher cost. The DRC's sediment-hosted copper-cobalt deposits are geologically unique — higher grade, lower cost, and irreplaceable at scale.
Chinese media outlets are also urging companies to bring in foreign capital from Saudi Arabia and the UAE as "shields" against US pressure, and to establish Western-standard audit trails to preempt legal challenges. This is defensive posturing of a kind China has rarely needed in Africa.
The Congolese People — Caught in the Crossfire
As Gerard Buunda, a 28-year-old economics student in Goma, told Al Jazeera: "We are exploited in mineral extraction. There are investors who make us work; sometimes they chase us off our land and force us to work for them in their mines for their own selfish interests."
The Rubaya collapse killed 400 people in mines controlled by M23 rebels — not by any multinational. But the global supply chain that purchases this coltan (ultimately destined for Apple, Samsung, Tesla, and others) creates the demand that makes artisanal mining economically rational despite the lethal risks. The mine reopened days after the disaster because the miners have no alternative livelihood.
Armed Groups — The Shadow Economy
M23's control of Rubaya generates over $800,000/month in taxation revenue. The broader conflict economy in eastern Congo involves dozens of armed groups controlling mines across North Kivu, South Kivu, and Ituri provinces. Rwanda has been repeatedly accused (and sanctioned) for backing M23, though Kigali denies this. The December 2025 DRC-Rwanda peace deal, brokered by the US, has not ended fighting on the ground.
Chapter 4: Scenario Analysis
Scenario A: US Successfully Diversifies Supply (35%)
Premise: The Glencore-Orion deal closes, Project Vault achieves critical mass, and Western processing capacity scales within 3-5 years.
Evidence:
- The DFC-ADQ sovereign backing provides patient capital that pure private equity cannot match
- Glencore's assets are world-class: Mutanda and Katanga are among the lowest-cost copper-cobalt operations globally
- The 2010 rare earth crisis precedent: when China restricted rare earth exports, Western firms invested $4.3 billion in alternative supply over 5 years, eventually breaking China's monopoly from 97% to 60% market share by 2020
Trigger conditions:
- Glencore-Orion MOU converts to binding agreement (expected Q2 2026)
- DFC commits >$2 billion in financing
- At least one US-based cobalt refinery begins construction
Timeline: 2-4 years to meaningful supply chain shift; 5-7 years to parity
Historical precedent: The rare earth diversification (2010-2020) took a full decade but succeeded in breaking China's effective monopoly. Critical difference: cobalt/copper deposits are more geographically concentrated than rare earths, making diversification harder.
Scenario B: Chinese Entrenchment — Status Quo Holds (45%)
Premise: China's 20-year head start, existing infrastructure, and relationships prove too entrenched to displace in the medium term.
Evidence:
- CMOC alone produces 40% of global cobalt — a single company's output exceeds the entire planned US response
- Chinese firms have built smelters, roads, railways, and processing facilities in Congo over two decades; the US has built almost nothing
- DRC's governance weakness means deals signed in Washington may not translate to operations in Kolwezi or Likasi
- Indonesia offers China a partial hedge: Indonesian cobalt production grew 340% between 2020-2025
Trigger conditions:
- Glencore deal stalls due to regulatory complexity or DRC political instability
- China offers Tshisekedi a counter-package (infrastructure, debt relief)
- CMOC production quotas are relaxed
Historical precedent: China's 2015 "Going Out" strategy in Africa saw Chinese FDI triple within 5 years despite Western criticism. When the Lobito Corridor (US-backed rail project) was announced in 2023, Chinese firms accelerated their own investments rather than retreating.
Scenario C: Resource Nationalism — Congo Takes Back Control (20%)
Premise: Kinshasa leverages US-China competition to renegotiate terms dramatically in Congo's favor, potentially nationalizing key assets.
Evidence:
- Chile's lithium nationalization (2023) demonstrated that resource-rich countries can extract better terms when multiple suitors compete
- DRC's 2018 mining code revision already increased royalty rates and government stakes
- Tshisekedi faces elections and domestic pressure to show tangible benefits from mineral wealth
- The Rubaya disaster creates political momentum for reform
Trigger conditions:
- DRC parliament passes a revised mining code requiring 35%+ state ownership
- A major renegotiation of the CMOC-Gécamines joint venture
- Sustained cobalt/copper price rally that increases Congo's leverage
Historical precedent: Zambia's 2019 attempt to raise mining taxes to 15% triggered capital flight and was partially reversed. Chile's more gradual approach (state lithium company + private partnerships) has been more successful. Congo's institutional capacity is weaker than either, making execution risky.
Chapter 5: Investment Implications
Direct Beneficiaries
- Glencore (GLEN.L): The $9 billion Orion deal values DRC assets at a premium; if completed, Glencore de-risks its Congo exposure while monetizing
- Ivanhoe Mines (IVN.TO): Direct participant in Project Vault; Kamoa-Kakula is the world's newest Tier-1 copper mine
- Cobalt/copper miners with DRC exposure: ERG, First Quantum (if it resolves its Zambia issues)
Indirect Beneficiaries
- Indonesian nickel-cobalt processors: If China accelerates diversification, Indonesian HPAL operations (Vale Indonesia, Harita Nickel) see increased demand
- Battery recycling firms: Li-Cycle, Redwood Materials benefit from supply chain anxiety
- Defense/strategic stockpile contractors: as Project Vault scales
At Risk
- CMOC (603993.SS): Directly threatened by US moves; DRC production quotas already limiting output
- Companies dependent on cheap Chinese-refined cobalt: Tesla, BYD, CATL face potential cost increases
- DRC sovereign bonds: Political instability risk from competing great-power pressures
| Asset Class | Impact | Historical Analog |
|---|---|---|
| Cobalt spot price | Upward pressure (10-20%) | 2018 DRC mining code revision → cobalt +35% |
| Copper (HG) | Supportive | 2010 rare earth crisis → copper collateral rally |
| DRC sovereign CDS | Widening | Zambia 2020 default precedent |
| Glencore equity | Positive catalyst | Rio-Glencore merger talks 2024 → +12% |
Conclusion
The Rubaya mine collapse and the US-China mineral scramble are not separate stories — they are two faces of the same crisis. The 400 dead miners were buried by the same geological forces that created the coltan deposits the world's technology industry depends upon. The US and China are competing for control of Congo's minerals, but neither superpower's strategy addresses the fundamental problem: a country with $24 trillion in resource wealth where mines are dug by hand, taxed by warlords, and workers die in numbers that would trigger national emergencies anywhere else.
The coming months will test whether Washington's aggressive resource diplomacy can actually displace China's entrenched position, or whether the Glencore-Orion deal becomes another in a long line of Western promises to Africa that never fully materialize. For the Congolese people, the answer matters less than a more basic question: will any of this wealth ever reach them?
