JAKARTA, April 21 (Reuters) - Miner Freeport McMoran Inc.'s Indonesia unit has been granted a permit to export 1.11 million wet metric tonnes of copper concentrate until February of next year, a trade ministry official said.

Oke Nurwan, director general of foreign trade at Indonesia's trade ministry, told Reuters the permit was valid until Feb. 16, 2018.

Production and exports at Freeport's mine in the eastern province of Papua have been disrupted due to a contract dispute between the company and the government. (Reporting by Bernadette Christina Munthe; Writing by Kanupriya Kapoor; Editing by Mark Potter)
