A miner was reported dead on Friday after a collapse at an underground US-owned mine in Indonesia’s Papua province, according to local media.

Indonesian news website Sindonews.com reported that the tunnel collapsed at 1 p.m. and buried alive a worker. It is still unclear if there were any other victims in the cave-in.

The tunnel was part of a mine operated by the Indonesian unit of Freeport-McMoRan Copper & Gold Inc.

There is still no official statement from Freeport Indonesia regarding the incident.

On May 14, a tunnel collapsed in the nearby Freeport mine, killing 28 workers who were undergoing safety training. Ten people were pulled alive.
