The CSA copper mine, in New South Wales, has lost three days of production, after a nearby storm damaged the main 132 kVA power line to the mine on Thursday evening.
All grid power was out to the mine for more than 26 hours, while the power line owner and operator restored the downed lines and infrastructure.
The loss of power and the associated restart of the mine will result in about 400 t to 500 t of copper production being deferred from the March quarter to the June quarter, said Metals Acquisition on Monday.
“All our people are safe and while approximately 50 mm of rainfall at the CSA copper mine was associated with this event, this has had no impact on operations due to the long-standing nature of the operation and its well-established systems for dealing with rainfall events,” the NYSE- and ASX-listed company stated.
