Located near Orange in central New South Wales, Cadia is one of the nation’s most productive gold and copper operations – and the nation’s only molybdenum mine. As expectations for more sustainable mining intensify, Cadia is playing an increasing role in supplying future-facing minerals to global markets.
PHE has supported Cadia for over 20 years, delivering electrical and instrumentation works across multiple asset upgrades. This latest engagement focused on modernising the chilled water systems servicing the SAG and Ball Mills – key components in the site’s high-throughput concentrator circuit.
Staged within a live processing environment, the works required shutdown-critical timing, interface management, and disciplined coordination. PHE was engaged to manage the complete E&I package – from early contractor involvement through to final commissioning – leveraging site familiarity and brownfield expertise to deliver safely and efficiently.
