Two miners who spent nine days underground in a collapsed zinc mine in South Korea managed to survive by consuming only instant coffee powder and water that fell from the ceiling, writes the BBC.

The men, aged 62 and 56, were trapped nearly 200 meters underground after part of the zinc mine they were working in collapsed on October 26 in Bongwa, in the east of the country.

They were finally rescued on the night of November 4 – more than nine days after their ordeal began. Both managed to get out of the mine and were taken to a local hospital, where doctors said they were in good condition.

South Korean President Yoon Suk-yeol says the rescue of the two miners was a “true miracle.”

According to the authorities, all this time the miners survived thanks to drinking water that fell from the ceiling and the use of instant coffee powder.

The rescue operation began on Thursday, when emergency services dug a hole and inserted a small camera to locate the miners. Rescuers found two on Friday.
