By the end of 2018, 4.9 Mozs Au had been mined from OceanaGolds Macraes mine in the South Island of New Zealand. A further 4.3 Moz remain in the gold resource implying a total gold endowment of >10 Moz.The Macraes gold deposit is located within the 1.5 km wide exposure of the Hyde-Macraes Shear Zone (HMSZ), a gently NE-dipping shear system that can be traced 20+ km along strike through the NE part of the Mesozoic Otago Schist (Figure 1). The HMSZ cuts chlorite zone quartzofeldspathic schists and is thought to have developed during late Jurassic contractional deformation along the margin of Gondwana. Mineralisation within the HMSZ occurred in the Early Cretaceous, towards the end of metamorphism, as the host schist was uplifted through the brittle-ductile transition.
