JAKARTA, Jan 25 (Reuters) - Freeport McMoRan Inc's copper concentrate export permit for its Indonesian unit will expire on Tuesday, Didi Sumedi, an official at the trade ministry told Reuters on Monday.
Last week, Indonesia's government stated that Freeport, which runs the massive Grasberg copper and gold mine, must put a further $530 million into an escrow account in order to get an extension to its export permit.
