Phu Kham Copper-Gold Operation
The Phu Kham Copper-Gold Operation is located within PanAust's Phu Bia Mining Contract Area in Laos approximately 140 kilometres from the capital city, Vientiane. Phu Kham is PanAust's flagship operation and 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 between 23 and 25 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.
March quarter 2017 production
The Phu Kham Copper-Gold Operation produced 22,751t of copper in concentrate at a C1* cost of US$1.15/lb after precious metal credits from 19,790 ounces (oz) gold and 139,644oz silver. An all-in sustaining cost (AISC**) of US$1.63/lb copper was achieved.
Overall copper recovery averaged more than 82 per cent for the quarter. Quarterly pay-metals in concentrate sales totalled 18,717t of copper, 16,221oz of gold and 127,332oz of silver.
Annual copper in concentrate production at Phu Kham is expected to peak between 85,000 and 90,000t 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 generally 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 2016.
