Five miners who were trapped last week after a mudslide flooded a shaft remain unaccounted for and are "now presumed deceased," the owners of the diamond mining company in South Africa said, announcing that it had filed for liquidation and shut the mine.
The incident occurred last Tuesday at the Ekapa Mine in Kimberley, the capital of Northern Cape province, when a sudden surge of water, mud and rock in minutes inundated an underground section of the mine, blocking access to its lowest mining level, about 800 metres underground.
The mine owners, Ekapa Resources and Ekapa Minerals, said despite rescue efforts that included drilling and assessments by specialist teams conditions were confirmed to be beyond survivable as tunnels were filled with mud and water with no signs of life. A search operation is ongoing.

At the same time, the owners announced the immediate closure of the mine where the incident occurred and petitioned the courts to be placed in liquidation.
The decision came after an internal evaluation found that, given the protracted worldwide diamond market downturn, exacerbated by the recent tragedy, the company is unable to continue meeting its financial responsibilities, it said.
"This marks the end of 158 years of continuous diamond mining in Kimberley," chief executive Jahn Hohne said in a statement. "A legacy the company acknowledges with humility and respect."
The National Union of Mineworkers of South Africa (Numsa), considered the largest single trade union in South Africa, told the state broadcaster it was "shocked" by the move, which puts the jobs of about 1200 workers at risk.
The union said it would be meeting with its legal teams to discuss a course of action to possibly block the liquidation.

"The situation is very devastating," Numsa Kimberley organiser Lerato Mohatlane told the SABC.
"If the mine is indeed liquidated, it is clear that all the 1200 workers will then lose their jobs."
The Department of Mineral Resources and Energy said it is set to meet with the firm and be briefed on what has transpired and ways forward.
South Africa is among the world's biggest producers of diamonds and gold, and the top producer of platinum.
