SnapshotThe Ban Houayxai Gold-Silver Operation is located approximately 25 kilometres west of PanAust’s Phu Kham Copper-Gold Operation. The PanAust’s Operations are transitioning from two large open pit mining operations to a combination of open pit and underground mines and potentially satellite ore feeds to the Phu Kham and Ban Houayxai processing plants.

Phu Bia Mining began its Ban Houayxai underground mine development in 2023 to further explore high-grade gold resources beneath the existing open pit.

The run of mine road at Ban Houayxai was switched to a new alignment to support the life of mine extension and provide linkage to the future Ban Houayxai Extension Project.

The Ban Houayxai underground mine, when in operation, is forecast to offer a multiple-year, high-grade ore resource with the potential to extend the life of the Ban Houayxai Operation well into the next decade.

Summary:

The Ban Houayxai Project is a vein hosted, structurally controlled gold-silver deposit of Permo-Carboniferous age (285Ma) in the north of the Lao People’s Democratic Republic. Mineralised veins are predominantly hosted within intermediate volcanics which have been subject to greenschist facies metamorphism and structurally juxtaposed against a siliciclastic package of lower metamorphic grade. The siliciclastic package contains mineralisation hosted within bodies of volcaniclastic siltstone and volcanogenic sandstone. The gold tenor of mineralised veins (quartz + pyrite ± carbonate ± base metals) within the Ban Houayxai deposit improves with increasing intensity of deformation.
