Positive results from a feasibility study have prompted PanAust to commit to an Aus$113.5 million expansion of its Phu Kham project.
The expansion will result in an increase in annual copper-in-concentrate production from the current 60,000-65,000 tonnes to 65,000-70,000 tonnes.
It will also result in annual production of 50,000 ounces of gold and 275,000 ounces of silver.
Phu Kham has proven and probable reserves of 168 million tonnes @ 0.62% copper, 0.24 grams/tonne gold and 1.9 grams/tonne silver for 1 million tonnes of copper, 1.31 million ounces of gold and 10.3 million ounces of silver.
The expansion has been designed to offset an expected decline in head grade from 2012.
Engineering and design for the expansion will begin almost immediately, with commissioning to begin in mid-2012 for a six-month ramp-up phase.
Annual throughput rates will increase from the current rate of 12 million tonnes to 16 million tonnes and flotation capacity will increase by 50%. Copper recoveries are expected to average 74-82% over the 10-year mine life.
The company says studies are continuing to determine the optimal mining fleet configuration.
