Ba n Houa yxa i Gold-Silver Opera tion

The Ban Houayxai Gold-Silver Operation is located in the Lao People’s Democratic Republic Continuous production s ince 2012Mining is by open-pit To the end of 2017 the mine had poured 0.65 million ounces of gold and 4.7 million ounces of s ilver.Ban Houayxai is an operating asset for PanAus t Limited, an Aus tralian-based copper and gold producer.

Identified areas that have possible problematic gold recovery.

Optimisation of drill and blas t to suit certain rock types .

Ideal mill s ettings (power draw, motor temperature, noise levels , recirculating load, etcetera) and processed with ideal settings (pH, cyanide levels , reagents , etcetera).

The MAXTA model, being a digital twin of the Operation, effectively provides information for risk analys is , cos t improvement s tudies , analys is and ‘what if’ s imulations for various scenarios .

The MAXTA model has been tes ted to provide both

estimate of the tailings gold grade as well as a probability

that a block will have a high tails grade.
