Newcrest’s Gosowong gold mine has suffered a serious ‘geotechnical event’ which has trapped one worker underground.
The incident occurred late last night, local time, at Gosowong’s Kencana underground mine – one of two underground operation at the site – on Halmahera Island, in Indonesia.
“The event caused damage to a number of mining levels,” Newcrest said in a company statement.
“The Kencana mine was evacuated immediately after the event and all personnel have been accounted for, except for one employee who is believed to be trapped approximately 300 metres underground.
“No other injuries have been reported.”
It is not yet known what caused the rockfall at the Kencana operation; whether it was mining related or due to seismic activity in the region.
Newcrest went on to state its main focus is to contact and rescue the trapped worker.
“All effort and specialist resources are being applied to the rescue,” it said.
"We will do whatever it takes to get to the trapped employee," a Newcrest spokesperson told Australian Mining.
“We have notified the family of the trapped employee and relevant Indonesian authorities.”
Once the rescue operations are underway, Newcrest will assess the extent of the damage the incident caused, and whether it has also affected the Toguraci underground operations.
All mining and processing operations have been suspended for the time being.
Newcrest's rescue teams are reporting credible indications its trapped employee is alive.
"We are very encouraged by this," a Newcrest spokesperson said.
They went on to add, "The situation remains very serious and we are completely focused on working quickly and safely to rescue our employee."
The trapped worker has been indentified as an Indonesian man from the local area around the Gosowong mine.
