SANTIAGO: The world’s largest underground copper mine was set to resume operating on Sunday, after a deadly cave-in suspended work for more than a week.

Chile’s Mining Ministry ordered El Teniente to halt activity on August 1 to allow rescuers to search for five miners trapped after a “seismic event” caused the collapse of a tunnel the day before.

All five were found dead.

Whether the cause of the shaking was due to an earthquake or drilling remains under investigation.

State-owned operator Codelco said normal operations would resume on Sunday.
