Gold miners are scouring rubble for more than 50 colleagues presumed dead after a pit collapse under the weight of heavy rain in eastern Democratic Republic of Congo.
Hundreds of young men in gumboots crowded around the site of Friday's cave-in, some removing rocks by hand from the muddy hillside, video footage showed.
Dozens of people die each year in accidents in largely unregulated artisanal mines in Congo, where often ill-equipped diggers borrow deep underground in search for ore.
Alexandre Bundya, mayor of the nearby town of Kamituga, Mpila, ordered two days of mourning.
The office of the governor of South Kivu province, Theo Kasi, said most of the victims were young people and expressed condolences to their families.
"The search continues to identify our deceased compatriots, bring assistance and implement measures to prevent incidents from repeating," his office said in a statement.
A World Bank report last year estimated the number of small-scale miners in Congo at two million, many more than work in industrial gold, copper and cobalt mines owned by companies like Glencore and Barrick Gold.
