Phu Kham Copper-Gold Operation
The Phu Kham Copper-Gold Operation is PanAust's flagship Operation. It is located within PanAust's Phu Bia Mining Contract Area in Laos approximately 140 kilometres from the capital city, Vientiane. The significant cash flow generated by the Phu Kham Operation has supported PanAust’s growth while contributing to a strong balance sheet.
The Operation comprises an open-pit mine feeding ore to a conventionally milling and flotation operation which produces a copper and precious metals concentrate for export to custom smelters mainly in Asia. The concentrate contains approximately 23 per cent copper, 9 grams per tonne (g/t) gold and up to 60g/t silver. Phu Kham's concentrate is trucked in covered containers with 80 per cent transported to the ports of Vung Ang or Hon La in Vietnam (approximately 650 kilometres from Phu Kham) with the remaining 20 per cent trucked to Sriracha Harbour in southern Thailand (approximately 1,000 kilometres from Phu Kham) for export to smelters mainly in Asia.
June quarter 2018 production
Production of copper in concentrate at Phu Kham totalled 21,201 tonnes (t) during the March quarter 2018. A C1* cost of US$1.24/lb copper was realised.
Copper, gold and silver head grades averaged 0.54 per cent, 0.25g/t and 2.32 g/t respectively. An overall copper recovery rate of more than 81 per cent was realised.
Quarterly pay-metals in concentrate sales totalled 21,183t of copper, 18,902oz of gold and 148,348oz of silver.
Annual copper in concentrate production at Phu Kham is expected to peak in 2018 and 2019 before subsequently declining with ore grade. No further development capital is currently expected to maintain these levels.
Gold in concentrate is expected to range between 70,000oz and 80,000oz per annum.
The Phu Kham Ore Reserve supports a mine life of approximately four years from the end of 2017.
