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.
Summary:
The mining operation comprises an open pit with a conventional blast-load-haul mining technique to mine the Ban Houayxai open pit in multiple stages.
