About PanAust and our operations
PanAust is an Australian incorporated company with its registered head office located in Brisbane, Australia, providing leadership and support across the Group.
PanAust’s producing assets, Phu Kham and Ban Houayxai, sit within its 1,260-square-kilometre Contract Area roughly 140 kilometres north of Vientiane in Laos and are operated through its subsidiary Phu Bia Mining Limited.

Phu Kham, an open-pit mine feeding a conventional milling and flotation circuit, produces a copper and gold concentrate which is exported to the international market via the Sriracha port in Thailand.
