Chile's Codelco makes initial progress toward trapped miners at El Teniente

Chilean state-run copper producer Codelco said on Friday that a rescue team had advanced four out of 20 metres (13 out of 66 feet) to reach five workers trapped inside its El Teniente copper mine after a major tremor.

Codelco Chief Executive Ruben Alvarado said no contact had yet been made with the trapped workers. The 4.2 magnitude quake occurred on Thursday around 5:30 p.m. local time at the mine's new Andesita unit, and killed one person.
