A man has died at a fly-in fly-out copper and gold mine in South Australia.
Mining company OZ Minerals and contractor Byrnecut said on Monday an underground mine worker was fatally injured at the Prominent Hill mine on Sunday afternoon.
"This incident has had a profound impact on our workforce and our priority is to ensure the safety and well-being of everyone at site," OZ Minerals boss Andrew Cole said.
"Byrnecut and OZ Minerals are providing support to the worker's family during this very difficult time."
Police said the 43-year-old from Aberfoyle Park in Adelaide was crushed by machinery and died at the work site.
State Resources Minister Dan van Holst Pellekaan said his heart goes out to the man's friends and family.
"Think about the people on site who would have found this person at work underground and who would have been closely involved in trying to save his life," he said.
"This is very sad, very serious and I know all of the workers and everybody in the company take it incredibly seriously and will do everything they can to discover what went wrong."
The death is being investigated by the South Australian Police and Safework SA.
The mine, which has an open pit, underground mine and processing plant, is about 650 kilometres northwest of Adelaide and 130 kilometres south-east of Coober Pedy.
Work at Prominent Hill have been temporarily suspended.
A report will be prepared for the state coroner.
