The Cadia Expansion Feasibility Study, remains on track to be submitted for Board approval by the end of December 2019. The next Cadia East block cave, PC2-3 includes establishing access and a ventilation system.
The Cadia Molybdenum Plant Feasibility Study has an estimated capital cost of $95m, with commissioning of the plant expected in FY22.
Cadia produces gold doré from a gravity circuit and gold-rich copper concentrates from a flotation circuit at Cadia. The gold dore is then refined at the Perth Mint and concentrates are piped to a dewatering plant at nearby Blayney and sent by rail to Port Kembla in New South Wales for export.
The Molybdenum Plant is expected to deliver an additional revenue stream in the form of a molybdenum concentrate which will be a by-product credit to AISC per ounce.
