Codelco to Produce Less Than Thought at Top Mine: Mercurio

Chile’s state copper miner Codelco said its biggest mine, El Teniente, will take longer to return to full production than originally forecast after a deadly tunnel collapse in July, according to El Mercurio.

This is due to the company’s caution in following safety protocols following the tunnel collapse that left six dead, the newspaper said, citing company chairman Máximo Pacheco.
