Xstrata has suffered a major power failure at its Ernest Henry mine, causing disruption to its underground operations.
The outage, which occurred earlier this week, occurred when the mine's main substation failed and caused a loss of power to the site and its accommodation.
At approximately 6:30pm on Monday 14 January, Ernest Henry Mining experienced a major power failure at our main substation. This caused a loss of power to our EHM operations and accommodation village, the miner said.
Despite the loss of power and its flow on effects, there have been no injuries.
"The health and safety of our personnel working on reinstating our power supply and our operations in general remains paramount," an Xstrata spokesperson said.
Ernest Henry Mining general manager Myles Johnston told Australian Mining that "our emergency response team has worked through recovery options to restore temporary power and essential services at the mine site, and underground operations are now back to normal.
However "our concentrator is not yet operational".
Xstrata's nearby Mount Margaret mine was not impacted and remains fully operational.
