Since war erupted between Sudan's regular army and the paramilitary Rapid Support Forces (RSF) in April 2023, both sides' war efforts have been largely funded by Sudan's gold industry.
In a statement, the Sudanese Mineral Resources Company (SMRC) said that the collapse occurred in an "artisanal shaft in the Kirsh al-Fil mine" in the remote desert area of Howeid, located between the army-controlled cities of Atbara and Haiya in Sudan's northeastern Red Sea state.
It did not mention when the collapse took place.
The war, now in its third year, has shattered Sudan's already-fragile economy, yet the army-backed government announced record gold production of 64 tonnes in 2024.
Africa's third-largest country is one of the continent's top gold producers, but artisanal and small-scale gold mining accounts for the majority of gold extracted.
In contrast to larger industrial facilities, these mines lack safety measures and use hazardous chemicals that often cause widespread diseases in nearby areas.
SMRC said it had previously suspended work in the mine and "warned against its continuing activity due to its posing great risk to life".
Before the war, which has pushed 25 million people into dire food insecurity, artisanal mining employed more than two million people, according to the industry.
Tens of thousands of people have been killed in Sudan, where over 10 million people are currently displaced in the world's largest displacement crisis.
A further four million have fled across borders.
