At least one worker died and five others were missing after a copper mine collapse in Chile triggered by an earthquake on Thursday, reports AFP, quoting the Chilean copper miner Codelco.
Nine others were injured, none critically, after the magnitude 4.2 earthquake struck at 5:34pm in the world's largest underground copper mine, El Teniente ("The Lieutenant"), Codelco informed.
"Codelco reports the death this afternoon of our colleague Paulo Marin Tapia," it said in a statement.
El Teniente is located in the city of Rancagua, about 100 kilometres from the capital, Santiago.
The United States Geological Survey reported a shallow magnitude 5.0 earthquake about 35 kilometres from Rancagua at 21:34 GMT.
Rescuers were working to enter the collapsed area, and "we have already reached some of them," Codelco President Maximo Pacheco told Cooperativa radio.
Chile is the world's leading copper producer and mines nearly a quarter of the global supply.
The valuable metal is used in wiring, motors and renewable energy generation.
