PanAust Ltd has reaffirmed its 2013 production guidance but warned cash costs are sensitive to prolonged gold price fluctuations.
In a statement to the Australian Securities Exchange, the miner said in the three months to June 30 it produced 15,483 tonnes of copper concentrate at its Phu Kham mine in Laos.
The total cash cost of production was $US2.12 ($A2.30) a pound for copper.
In the same period, gold in concentrate production was 16,092 ounces.
The company estimates consolidated full-year production of 62,000 to 65,000 tonnes of copper concentrate.
It estimates precious metal production in concentrate and doré of 160,000 to 175,000 ounces of gold and 1.1 million to 1.2 million ounces of silver for the full year.
