The US miner Freeport-McMoRan has restarted concentrate shipments from Indonesia's Papua region after a three-month strike ended in December.
An official at a smelter, which is part-owned by Freeport, has told Reuters it is a sign that work at the world's second largest copper mine is returning to normal.
The official, Dwi Bagus, declined to say when shipments restarted or the quantity of concentrate the smelter received.
In October, Freeport declared force majeure as it was hit by the strike at its Grasberg mine by workers seeking substantial pay hikes.
