SANTIAGO - The surprise exit of Chilean mining firm Codelco's CEO will put the state copper giant in a bind, analysts and insider sources said, even as it tries to revive flagging production of the red metal and make a foray into electric-vehicle mineral lithium. The world's largest copper producer said on Tuesday that chief executive officer André Sougarret would step down by the end of August, only a year after he took the role, citing "complexities" around the business and personal strain.
