Otago Gold District

Active Mining Region

Otago Schist Gold Belt

  • Otago Gold Belt hosted within the core of a large schist belt located in South Island of New Zealand
  • High grade gold occurs within quartz lodes (ore shoots) along steeply-dipping NW and NE trending shear zone known as the Hyde-Macraes Shear Zone (HMSZ) – over 30 km long
  • TSX-listed OceanaGold’s active Macraes Mine producing in extensive shear & quartz stockwork ore zones within HMSZ
  • ASX-listed Santana Minerals’ Bendigo-Ophir Project is located adjacent to KO Gold’s properties and contains an Indicated and Inferred JORC Resource of 2.2 Moz at 2.2 g/t Au1 in four Rise and Shine Shear Zone (RSSZ) deposits. The RSSZ is along the same trend as HMSZ within Smylers Gold Project

Gold Production

  • 8.5 Moz Au within alluvial deposits, and over 5 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
  • Bendigo-Ophir Project moving quickly to next stage including metallurgical testing programs and scoping studies and large infill drilling programs
  • According to Santana, Bendigo-Ophir Gold Project could become the next open-pit gold mine in the Otago Gold District

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 by KO Gold and others

The MRE information disclosed on adjacent properties has not been verified by the QP and this information is not necessarily indicative of the mineralization on KO Gold’s properties in the Otago Gold District

Exploration and Drilling Plans

Sep 2023 – Feb 2024


  • 3D Modelling and Data Interpretation
  • Structural mapping to extend HMSZ to the east
  • Desktop studies and drill hole targeting for Smylers, Hyde, Rough Ridge South, and Carrick goldfields

Feb 2024 – Apr 2024

(Planning Phase)

  • Selecting drilling targets for RC and diamond drilling and permitting process
  • Diamond drilling will be focused on confirming ore shoots containing high grade gold (>6m thicknesses and 1 to 4 g/t)

Oct 2023 – Dec 2023

(Drilling Phase)

  • RC and diamond drilling at Smylers targeting areas with resource potential
  • Exploration & scout drilling at Hyde and Carrick goldfields targeting high grade gold mineralization in known historical mining areas


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

KO Gold Projects

  • Well-positioned permit-wise adjacent to OceanaGold’s Macraes Mine and near Santana Mineral’s resource-stage Bendigo-Ophir Gold Project
  • Additional drilling required to discover potentially economic ore shoots throughout the projects
