Otago Schist Gold Belt

  • Gold hosted in Lower Greenschist and Upper Greenschist facies within core of schist belt
  • High grade gold occurs within quartz lodes along steeply dipping NW and NE trending shear zones known as the Hyde-Macraes Shear Zone (HMSZ) – over 30 km long mineralized trend
  • Macraes Mine has extensive shear and quartz stockwork zones forming high grade ore shoots
  • ASX-listed Santana Minerals’ Bendigo-Ophir Project is located 90 km NW of Macraes Mine and contains a 2.4 Moz inferred gold resource in four Rise and Shine Shear Zone (RSSZ) deposits, which remain open down-plunge. The RSSZ is along the same trend as HMSZ within Smylers Gold Project

Gold Production

  • 8.5 Moz Au within alluvial deposits, and 5.2 Moz Au within hard rock deposits of which majority produced at Macraes Mine since 1990
  • Historical workings targeted high grade veins and included small open-pit operations

Smylers Gold Project

Southeast of Macraes Mine

  • Seven distinct gold targets discovered immediately southeast of Macraes Mine in Smylers Gold area
  • Smylers Gold Project includes the eastern extension of the HMSZ
  • These gold targets discovered through structural mapping, soil and stream sediment sampling, 3D IP/Resistivity surveys, trenching, and closely-spaced RC and diamond drilling


Otago Gold District

  • World-Class Gold Mining District
  • >14 Moz Historical Production (alluvial and hard rock combined)
  • Major Discovery Potential In Underexplored Areas

Macraes Gold Mine

  • Low-Cost Active Gold Mine
    (2021 AISC Outlook: US$1,000 – 1,100/oz)
  • Mill and Infrastructure Onsite
  • Multi-year Expansion Plan
  • Macraes Watching Our Progress

Smylers Gold project

  • Immediately Adjacent To Macraes Mine Complex
  • Future Macraes Mine Expansion Potential Exit Strategy
  • Additional Drilling Required To Discover Economic Ore Shoots
