Ban Houayxai Gold-Silver Operation

The Ban Houayxai Gold-Silver Operation is located approximately 25 kilometres west of PanAust's Phu Kham Copper-Gold Operation.

Commencing production in 2012, Ban Houayxai comprises an open-pit mine feeding ore to a conventional carbon in leach and gravity recovery process.

September quarter 2019 production

During the June quarter 2019, the Ban Houayxai Operation poured 21,984 ounces (oz) of gold and 152,584oz of silver in doré for a C1* cost of US$884/oz gold. An all-in sustaining cost (AISC**) of US$1,105/oz gold was released.

The Operation mined more than 4.2 million tonnes (Mt) of ex-pit material which included more than 1.3Mt of gold-silver ore. Over 1.2Mt of ore was processed.

Award-winning operation

In October 2018, the Operation retained its Caterpillar 5-star contamination control ratings for its mobile maintenance workshop and associated supply facilities. This was the sixth consecutive year Ban Houayxai achieved this highest rating.

Ban Houayxai was designed in accordance with the International Cyanide Management Code (the Code) - a voluntary program for the responsible manufacture, transport, use and disposal of cyanide in the production of gold. The Operation received pre-operational certification in 2012, operational certification in 2013, and was recertified in 2016.

In 2013, PanAust received the Project Development of the Year Award at the Mines and Money Hong Kong Asia Mining Awards. The accolade recognised the application of outstanding project management during the development of the Ban Houayxai Gold-Silver Operation.
