In the mineral‑rich hills of North Kivu province, the fragile earth shifted without warning this week, turning a place of hard work and quiet hope into a scene of loss and anguish. At the Rubaya coltan mine in eastern Democratic Republic of the Congo (DRC), a collapse triggered by heavy rains buried dozens of artisanal miners, market workers, and even children — and officials now say more than 200 people have been killed in one of the deadliest mining tragedies the region has seen.
The disaster unfolded on Wednesday when the unstable ground gave way at the Rubaya site, where locals dig manually for coltan — a metallic ore processed into tantalum, a heat‑resistant element used in mobile phones, computers, aerospace components, and many electronic devices worldwide. The site accounts for roughly 15 percent of the global coltan supply, making it both economically vital and perilously crowded with workers scraping a living from the earth.
Lumumba Kambere Muyisa, spokesperson for the rebel‑appointed governor of North Kivu, said the collapse occurred during the region’s rainy season, when saturated soil and erosion can weaken informal mine shafts. “More than 200 people were victims of this landslide, including miners, children, and market women,” Muyisa told Reuters. At least 227 deaths has been cited by an anonymous adviser to the governor, though exact figures are still being refined as rescue teams search through mud and debris for survivors and the bodies of the missing.
The collapse highlights both the human cost of unsafe mining conditions and the larger humanitarian crisis afflicting eastern Congo. Rubaya is under the control of the M23 rebel group, which seized the region in 2024 and has since profited from taxing the coltan trade. The United Nations has accused M23 of exploiting mineral resources to fund its insurgency — an allegation Kigali denies — and ongoing violence in the region has contributed to one of the world’s largest displacement crises, with millions uprooted by conflict over decades.
In the aftermath, injured survivors are receiving treatment in local health facilities, while ambulances have been dispatched to transfer more serious cases to Goma, the provincial capital. Officials have suspended artisanal mining at the site and ordered nearby residents to relocate for safety reasons, even as grieving families await news of loved ones still unaccounted for.
This tragedy once again underscores the precarious intersection of poverty, conflict, and the global demand for critical minerals. For the men, women, and children drawn daily into the depths of Rubaya’s pits — often for only a few dollars a day — mining is both a means of survival and an ever‑present risk. As the full toll becomes clearer, the community and the world face the heavy task of mourning and reflection about how to better protect those who work at the foundations of modern technology and commerce.
