Landslide at rebel held Rubaya coltan mine buries Over 200 miners in Eastern Congo
The verdant hills of North Kivu have once again turned into a graveyard. Rescue efforts were effectively paralyzed this weekend following a catastrophic landslide at the Rubaya mining site in eastern Congo, where local rebel authorities fear at least 200 artisanal miners have been buried alive. The disaster, which struck late Wednesday following days of torrential rain, is the latest and deadliest in a grim series of accidents to plague the world’s most vital source of coltan.
Witnesses describe a scene of sudden devastation. A sodden hillside, honeycombed with handmade tunnels and pits, gave way without warning, swallowing hundreds of diggers/miners who were working the rich seams of black ore below.
"The mountain just came down", said Clovis Mafare, a miner who narrowly escaped the collapse. "People dig everywhere without safety measures. In a single pit, there can be 500 people. When the tunnels collapsed, they took everyone with them".
The tragedy is compounded by the complex geopolitical web surrounding Rubaya. The area is currently under the control of the M23 rebel group, which seized the territory in mid-2024. The group’s spokesperson, Lumumba Kambere Muyisa, confirmed the casualty estimates on Saturday, stating that heavy rains triggered the landslide and that recovery operations were being hampered by the mud and lack of heavy machinery.
The Congolese government in Kinshasa has issued a statement expressing solidarity with the victims while accusing the rebels of "illegal and unsafe exploitation" of the country's natural resources. However, for the families waiting in the rain for bodies that may never be recovered, the blame game offers little solace.
This collapse serves as a brutal reminder of the human cost of modern technology. The minerals extracted from these perilous pits are often by hand, by men and children earning less than a few dollars a day that are the essential lifeblood of the global electronics industry, destined for the smartphones and laptops of consumers worldwide.
Background & Context
Beyond the immediate news of the collapse, here is a detailed breakdown of the mineral involved, the history of such accidents, and the systemic reasons they continue to occur.
What is Coltan?
Coltan is the industrial colloquial shorthand for columbite-tantalite. It is a dull black metallic ore from which the elements niobium and tantalum are extracted.
- Tantalum is the key prize. It is highly heat-resistant and can hold a high electrical charge.
- The Democratic Republic of Congo (DRC) holds over 60% of the world's coltan reserves.
What are its uses?
Coltan is critical to the modern digital age. Because tantalum is excellent at storing electricity in small capacitors, it allows manufacturers to miniaturize electronic devices without losing performance. It is used in:
- Consumer Electronics: Nearly every smartphone, laptop, tablet, and gaming console contains tantalum capacitors.
- Automotive Industry: Electric vehicles (EVs), GPS systems, and anti-lock braking systems (ABS).
- Aerospace & Defence: Jet engines and missile guidance systems (due to their extreme heat resistance).
- Medical Devices: Pacemakers and hearing aids.
Recent Major Mine Collapses in Congo
The disaster in Rubaya is not an isolated incident; it is part of a deadly pattern in the region.
- June 2025 (Rubaya): A massive landslide in the same mining area (Rubaya) reportedly killed over 300 people. The collapse devastated an area of unlicensed mining known as Bibatama.
- November 2025 (Kalando): A bridge collapse at a copper/cobalt mine in Lualaba province killed between 30 and 50 miners. Panic ensued after security forces reportedly fired shots, causing a stampede onto a makeshift bridge.
- May 2023 (Songambele/Rubaya): A slope failure at a coltan mine killed at least six, though local civil society groups estimated over 100 were missing and unaccounted for.
- September 2020 (Kamituga): Torrential rains caused a gold mine collapse in South Kivu, killing at least 50 artisanal miners.
Why is this so common in the Congo?
The frequency of these disasters is driven by a "perfect storm" of four factors:
1. Artisanal "Wildcat" Mining Unlike industrial mines that use open-pit terraces and engineers to ensure stability, artisanal mining involves digging vertical shafts and horizontal tunnels by hand.
- No Supports: These tunnels rarely have support beams or ventilation.
- Swiss Cheese Effect: Thousands of diggers riddle a single hill with tunnels. When one tunnel collapses, it triggers a domino effect, bringing down the entire hillside.
2. The Conflict Economy Eastern Congo has been plagued by armed conflict for decades (over 100 armed groups operate in the region).
- Rebel Funding: Groups like the M23 use mines to fund their operations. They tax the production but invest nothing in safety or infrastructure.
- Lack of Oversight: Because these areas are war zones or rebel-held, state mining inspectors cannot visit to enforce safety regulations.
3. Geological and Climatic Factors
- Rainy Season: The region experiences intense tropical rainfall. The soil, already loosened by digging, becomes waterlogged and heavy, making landslides inevitable.
- Soft Soil: The geology of the region involves soft, red clay that is easy to dig by hand but structurally unstable.
4. Extreme Poverty Despite the danger, locals flood these mines because they have no other options.
- Economic Desperation: With 70% of the population living on less than $2.15 a day, the chance to find a "pocket" of coltan is worth the risk of death.
- Child Labor: The lack of regulation means children often work in the mines or in the streams washing the ore, exposing them to the same landslide risks as adults.
