Ernest Giles

Located approximately 250km north-east of the town of Laverton in the Yilgarn region of Western Australia, Ernest Giles consists of five granted Exploration Licences covering an area of approximately 1,323km² and three Exploration Licence applications covering an area of approximately 643km².

The Ernest Giles project overlies the eastern most identified Archean greenstone belt of the Yilgarn craton. Archean greenstones of the Yilgarn craton are host to the dominant majority of western Australian gold and nickel endowment including the Kalgoorlie super pit. The Ernest Giles project is considered by Greatland to be virtually unexplored in comparison to every other belt in the Yilgarn.

Historic exploration at Ernest Giles commenced in the mid-1990’s and included sampling and RC drilling, however, no significant mineralisation was discovered.

Notable exploration by Greatland:

  • Greatland acquired the Calanchi (E38/2205) tenement in 2010. In 2012 RC drilling (4 holes) identified gold anomalism at the Meadows prospect with a peak of 1m at 1.15g/t Au from 149m depth in ERC002A;
  • An additional 30 RC holes drilled in 2018 for 8,627m intersected low level gold anomalism and confirmed the previously identified mineralisation. Two Additional diamond holes were drilled in 2023 to provide further structural stratigraphic information; and
  • Greatland completed a 3D induced polarisation (IP) electrical survey over the Meadows prospect commenced in March 2025 and intends to follow this up with a 8,000m of RC and diamond drilling in 2025.
