On Thursday, the first fatality was reported since part of the mine collapsed after an earthquake with a magnitude of 4.2.
Then, the mining company Codelco stated that five other miners were trapped and that a barrier of about 90 meters of rubble at a depth of 900 meters in a new part of the mine would be forced to try to find them.
About 100 people participated in the effort to step by step make their way through the mine tunnels. On Saturday, the second deceased was found and on Sunday the remaining four.
On Sunday morning, the rescue personnel had cleared 24 meters of blocked passages, according to Reuters.
Chile accounts for nearly a quarter of the world's copper production, and the mine produced almost seven percent of the country's copper last year.
