A 26-year-old man has died following an accident at Glencore’s CSA Copper mine in Cobar, New South Wales.
The man was working underground at 11.15pm on Wednesday when he became trapped in a pipe.
NSW Police said the man was attempting to dislodge debris from the pipe which was attached to a piece of machinery, before he became trapped.
A NSW Police spokeswoman said the man was "sucked inside the pipe", but no further details were provided.
Colleagues freed the man a short time later.
Paramedics attempted to resuscitate the man, who was conveyed to Cobar Hospital however he could not be revived.
Glencore said production at the mine has been suspended while police and Work over investigate the incident.
"We are cooperating with the NSW Police and other authorities who are investigating the fatal event, and have notified the man's family," Glencore said.
"Our primary concern is for the safety and welfare of our people, and we are offering counselling and support services on site."
