At least 200 people have been killed when a landslide collapsed several mines at a major coltan mining site in eastern Congo, rebel authorities say.

The collapse took place on Wednesday at the Rubaya mines, which are controlled by the M23 rebels, Lumumba Kambere Muyisa, the spokesperson of the rebel-appointed governor of North-Kivu province told The Associated Press.

He said the landslide was caused by heavy rains.

"For now, there are more than 200 dead, some of whom are still in the mud and have not yet been recovered," Muyisa said.

He added several others were injured and taken to three health facilities in the town of Rubaya, while ambulances were expected to transfer the wounded Saturday to Goma, the nearest city around 50km away.

The rebel-appointed governor of North Kivu has temporarily halted artisanal mining on the site and ordered the relocation of residents who had built shelters near the mine, Muyisa said.

Rubaya lies in the heart of eastern Congo, a mineral-rich part of the Central African nation which for decades has been ripped apart by violence from government forces and different armed groups, including the Rwanda-backed M23, whose recent resurgence has escalated the conflict, worsening an already acute humanitarian crisis.

Over 15 per cent of the world's supply of tantalum, a rare metal extracted from coltan that is a key component in the production of smartphones, computers and aircraft engines, comes from the Rubaya region.

In May 2024, M23 seized the town and took control of it mines. According to a UN report, since seizing Rubaya, the rebels have imposed taxes on the trade and transport of coltan, generating at least $US800,000 a month.

Eastern Congo has been in and out of crisis for decades. Various conflicts have created one of the world's largest humanitarian crises with more than seven million people displaced, including 100,000 who fled homes this year.

Despite the signing of a deal between the Congolese and Rwandan governments brokered by the US and ongoing negotiations between rebels and Congo, fighting continues on several fronts in eastern Congo, continuing to claim numerous civilian and military casualties.

The deal between Congo and Rwanda also opens up access to critical minerals for the US government and American companies.
