LIMA - Peru, the world’s third biggest copper producer, closed its main port, Callao, and dozens of others because of rough seas, a local newspaper reported Saturday. The ports will likely remain closed through Monday, when a storm in the South Pacific is expected to have moved north, La Republica said, citing the Navy. The closure threatens to delay mineral shipments in Peru, a supplier of zinc, gold and silver. Navy and port officials could not be reached for comment outside of regular working hours.
