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.

March quarter 2021 production

During the March quarter 2021, the Ban Houayxai Operation poured 29,826 ounces (oz) of gold and 244,555oz of silver in doré for a C1* cost of US$504/oz gold. An all-in sustaining cost (AISC**) of US$767/oz gold was released.

The Operation mined more than 3.8 million tonnes (Mt) of ex-pit material during the quarter which included 1.1Mtt of gold-silver ore. Over 1.2Mt of ore was processed.

Gold and silver doré sold during the quarter totalled 24,962oz and 234,701oz respectively.

Award-winning operation

During the December quarter 2020, the Operation retained its Caterpillar 5-star contamination control ratings for its mobile maintenance workshop and associated supply facilities. This was the eighth consecutive year the Ban Houayxai Operation has 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 2019.

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.
