The Otago Regional Council has received applications from Oceana Gold (New Zealand) Limited for resource consents for various activities as part of the Macraes Phase III (MPIII) expansion at Macraes Flat, North Otago. These activities include:
- Decommissioning of part of the Southern Pit Impoundment (SPI) tailings storage facility;
- Decommissioning of the Mixed Tailings Impoundment (MTI) tailings storage facility and reutilising the structure as a reclaimed tailings stack;
- Extension of the Round Hill – Southern Pit, which may result in the alteration of the MTI tailings dam/reclaimed rock stack;
- Extension of Frasers Pit and the re-opening and extension of Innes Mills Pit;
- Creation of the Back Road Rock Stack;
- Extension of the Frasers North and South Rock Stacks;
- Creation and operation of the Top Tipperary Tailings Storage Facility (TTTSF); and
