At least 200 people have died in a tragic collapse at the Rubaya coltan mines in eastern Democratic Republic of Congo, authorities confirmed, with more than 30 others injured. The disaster occurred on Wednesday in North Kivu province, an area controlled by M23 rebels since May 2024, when landslides brought down artisanal mining sites where miners, vendors, and their families were present.

Lumumba Kambere Muyisa, spokesperson for the rebel-appointed provincial governor, confirmed the death toll and detailed the ongoing rescue efforts, which have been hampered by poor road conditions, continued insecurity, and unstable terrain. Those affected include miners, women, children, and local vendors who rely on the mine for livelihoods.

The Rubaya mines are a key source of coltan, producing roughly 15% of the global supply. Coltan is refined into tantalum, a critical component used in smartphones, electric vehicles, and other high-tech electronics. The tragedy highlights the risks inherent in unregulated artisanal mining operations, where thousands work without proper safety equipment or oversight.

In response to the disaster, rebel governor Bahati Musanga Erasto ordered an immediate halt to all mining operations in the area and instructed local residents to relocate to safer shelters to prevent further casualties. Authorities have called for international assistance to support rescue and recovery efforts, as well as longer-term measures to improve safety and prevent future disasters in one of the world’s most significant coltan-producing regions.

This catastrophic event underscores the persistent dangers faced by workers in informal mining sectors and the need for stronger regulatory oversight, particularly in regions plagued by conflict and limited infrastructure.
