Cadia East underground mine is designed to treat 27 million tonnes of ore annually, with a forecast output of approximately 800,000 ounces of gold, making it both the largest underground mine in Australia and one of the largest gold producers worldwide.
To achieve this level of production, Newcrest invested heavily in state-of-the-art crushing and ore handling systems, supported by high-capacity electrical infrastructure. PHE was engaged as the major electrical and instrumentation (E&I) contractor, responsible for the installation and commissioning of these systems along with associated ancillary equipment. The project included installation of cable support systems, high voltage switchgear and reticulation system, low voltage cabling, MCC installations and fibre optic cabling.
