Diversified Minerals has confirmed that a PYBAR Mining Services contract worker has been trapped underground at the Henty gold operation in Tasmania after part of the mine collapsed.
The company has suspended operations and emergency services including Tasmania Police and Ambulance Tasmania are helping with the search for the worker.
Work Safe Tasmania and the Mines Inspector have also been notified about the incident.
The missing man is the only person unaccounted for after the accident, according to Diversified.
Tasmania Police will use a thermal imaging drone and a robotic camera to search the area of collapsed earth for the worker.
Officers from the bomb response group, the chief police pilot and ambulance workers are also preparing to head underground as safely as possible, approximately 50 metres from the area of collapsed earth.
The emergency rescue team plans to use information from the drone and camera to locate the missing man and develop an evacuation plan.
The worker was trapped at around 4am this morning after his colleagues could not communicate with him and entered the area he was working, which is about a 20-minute descend underground.
His three colleagues found a section of collapsed earth and were unable to find their co-worker and went back to the surface to raise the alarm.
“Our immediate priority is to ensure the welfare of the person not accounted for and the safety of those involved in the rescue,” PYBAR chief executive officer Brendan Rouse said.
“PYBAR are working closely with the Henty site team to establish the extent of the affected area. We are doing everything possible to ensure we access the area as safely and as quickly as possible.”
Diversified will provide further information as it becomes available.
