LONDON-- Copper miner Antofagasta PLC (ANTO.LN) Wednesday said all its mines in the north of Chile have now resumed normal operations after being suspended following heavy rains in the Atacama Desert.

Operations had been suspended, primarily for the safety of employees and others who work at the mines, but some processing of stockpiled material was possible and continued over the period, the company said.

"Although some production has been lost since the heavy rains started on 24 March, the Group will work to minimise this during the course of the year," it added.

Shares at 0934 GMT, down 7 pence, or 0.9%, at 726 pence valuing the company at GBP7.2 billion ($10.7 billion).
