Nine workers trapped inside a wildcat mine in southern Peru received oxygen and liquids through a giant hose on Saturday while a rescue team toiled to get them out, officials said.
The men have been stuck about 656 feet (200 meters) below ground since the Cabeza de Negro gold-and-copper mine partially collapsed on Thursday.
“We’ve communicated with them and they are in good health, thankfully,” police officer Jose Saavedra told local radio.
A regional health official, however, said the miners were suffering from dehydration and feelings of desperation.
Small illegal mines are common in Peru, generating as much as $2 billion a year in income, according to private estimates.
Peru’s mining sector accounts for 60 percent of total exports.
