The Hidden Valley Gold Project included the construction of a 4.2 Mt/y Gold Processing Plant in the remote highlands of Papua New Guinea, approximately 150 km south of Lae, Morobe Province. The expected annual production from the mine is 300,000 oz of gold and 4.5 Moz of silver per annum.

Ausenco’s scope was for the provision of the full EPCM services for the design, construction and commissioning of the project including the process plant, site access roads, water supply, power supply, site accommodation and associated infrastructure.
