All five trapped Chilean miners found dead

All five trapped workers at Chile's Codelco's El Teniente copper mine have been found dead.

Prosecutor Aquiles Cubillo of the O'Higgins region said on Sunday the body of the fifth trapped worker had been found after rescue teams cleared more than two dozen metres of underground passages that collapsed in a strong tremor last week.

The latest fatality brings the total death toll from the accident to six, including one person who died at the time of the incident on Thursday evening.

Codelco discovered the first trapped worker on Saturday and another four on Sunday.

The collapse was triggered by one of the largest tremors ever recorded at El Teniente, with the impact of a 4.2 magnitude quake.

Codelco is investigating whether the cause was mining activity or natural tectonic shifts in the earthquake-prone country.
