Latitude & Longitude (WGS84): 45° 22' 34'' South , 170° 27' 1'' East
Latitude & Longitude (decimal): -45.37620,170.45040

Open-cast gold mine working gold-scheelite deposits in lode shears, stockworks and disseminated stockworks within the gently dipping Hyde-Macraes Shear Zone (although scheelite is not being currently extracted due to metallurgical difficulties). Mined from a series of open pits extending 6km.

Located close to the settlement of Macraes Flat, and 15 km west of Palmerston and 80 km north of Dunedin, eastern Otago.
The Macraes Mine started in 1990, and in 2003 produced about 5,000 kilograms of gold. Production from 1990-2013 ~3 Moz of gold.

Owned by Oceana Gold Corporation.
