SANTIAGO, Aug 3 (Reuters) - Four of five trapped workers at Codelco's El Teniente copper mine have been found dead, the company said on Sunday, as rescue teams work to clear underground passages that collapsed in a strong tremor last week.

Rescuers have recovered the bodies of four miners and are searching for two more after an earthquake caused a partial collapse at El Teniente mine last week.

At least 100 rescuers are still looking for miners who are trapped in the partially collapsed mine in Rancagua, south of Chile's capital Santiago. Over 100 rescuers have been taking part in an operation to find five trapped miners at the site in Rancagua,
