Cadia

Cadia is a gold mining complex in the Central West region of New South Wales, Australia. Located near the village of Cadia, about 25 kilometers southeast of Orange, it lies within Blayney Shire. The Cadia Valley Operations (CVO) is one of Australia’s largest active gold mines and is owned and operated by Newcrest Mining. The complex includes the Cadia-Ridgeway open-pit mine and the Cadia East underground mine, together with processing facilities at the Cadia processing plant.

Ore from the mines is processed to produce doré bars, with concentrate shipped to refineries. The operation employs a substantial workforce of direct employees and contractors and is a major contributor to the regional economy. Cadia’s production has made it a significant asset for Newcrest and for Australian gold supply.

Development of the Cadia East underground project extended the life of the operation beyond the original open-pit resources. The site has also invested in water management, tailings storage, and progressive rehabilitation to minimize environmental impact.
