Phu Kham Copper-Gold Operation
The Phu Kham Copper-Gold Operation is PanAust's flagship Operation.
The Operation is located within PanAust's Phu Bia Mining Contract Area in Laos approximately 140 kilometres north of Laos' 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, 6 grams per tonne (g/t) gold and up to 47g/t silver.
Seventy five per cent of Phu Kham's concentrate is trucked in covered containers to the port of Hon La in Vietnam (approximately 650 kilometres from the Operation). The remaining 25 per cent is trucked to Sriracha Harbour in southern Thailand (approximately 1,000 kilometres from Phu Kham) for export to smelters mainly in Asia.
June quarter 2019 production
During the June quarter 2019, the Phu Kham Operation produced 17,863 tonnes (t) of copper in concentrate at a C1* cost of US$1.16/lb after precious metal credits from 16,455 ounces (oz) of gold and 95,161oz silver. An all-in sustaining cost (AISC**) of US$1.78/lb of copper was realised.
More than 10.8 million tonnes (Mt) of ex-pit material was mined during the quarter which included 4.1Mt of copper-gold ore.
Copper, gold and silver head grades averaged 0.43 per cent, 0.19 grams/tonne (g/t) and 1.47g/t respectively. An overall copper recovery rate of more than 80 per cent was achieved.
Quarterly concentrate sales totalled 18,221t of copper, 17,091oz of gold and 107,519oz of silver.
