Highlights

Additional drilling has expanded the growing northeast extension area, which remains open with follow-up and step-out drilling underway. This zone is characterised by near surface, high-grade mineralisation at the northeastern limit of drilling at Warintza Central and represents a priority target for further growth.

  • SLS-54 was collared at the northeastern limit of the grid and drilled into an open volume near surface, returning 356 m of 0.73% copper equivalent (CuEq) from 50 m depth within a broader interval of 1093 m of 0.56% CuEq from surface.
  • This follows from near surface, high-grade mineralisation previously reported from:
    • SLS-49: 396 m of 0.7% CuEq from 50 m depth within 817 m of 0.6% CuEq.
    • SLS-48: 100 m of 1.64% CuEq from 50 m depth within 852 m of 0.56% CuEq.
    • SLS-42: 740 m of 0.6% CuEq from 52 m depth within 906 m of 0.53% CuEq.
    • SLS-38: 244 m of 0.7% CuEq from 58 m depth within 822 m of 0.35% CuEq.
    • SLS-34: 242 m of 0.67% CuEq from 52 m depth within 660 m of 0.47% CuEq.
    • SLS-32: 372 m of 0.64% CuEq from 46 m depth within 618 m of 0.48% CuEq.
  • Follow-up drilling from existing platforms is underway, with a 260 m northeast step-out platform recently completed and a second platform stepping out further to the northeast under construction.

Additional drilling has expanded the growing southeast extension area, which remains open in near surface, high-grade mineralisation.

  • SLS-52 was collared on the eastern side of the grid and drilled southeast into an open volume near surface, returning 482 m of 0.62% CuEq from 96 m depth, within a broader interval of 977 m of 0.45% CuEq from near surface that infilled drilling at depth.
  • SLS-53 was collared from a southeastern platform and drilled south into an open volume near surface, returning 176 m of 0.78% CuEq from 16 m depth, within a broader interval of 957 m of 0.46% CuEq from 10 m depth that infilled drilling at depth.
  • This follows from near surface, high-grade mineralisation previously reported from:
    • SLS-45: 236 m of 0.56% CuEq from 44m depth within 564 m of 0.41% CuEq.
    • SLS-39: 368 m of 0.73% CuEq from 90 m depth within 915 m of 0.56% CuEq.
    • SLS-35: 326 m of 0.8% CuEq from 50 m depth within 920 m of 0.62% CuEq.
  • Additional platform construction to support follow-up and step-out drilling to test the further southeast extension of near surface, high-grade mineralisation is planned, following the release of the updated mineral resource estimate.
  • SLS-51 was collared from the south-central portion of the grid and drilled east into an open volume at surface, returning 918 m of 0.5% CuEq from 130 m depth within a broader interval of 1012 m of 0.47% CuEq from near surface that infilled drilling at depth.
  • Updated Warintza Central mineral resource estimate expected to be issued in April.
  • To date, 62 holes have been completed at Warintza Central, with assays reported for 54 of these.

Jorge Fierro, Vice President, Exploration, commented: “These final holes expand on two key growth areas with near surface, high-grade mineralisation on the edge of resource drilling that remains open. These holes will be included in the forthcoming resource update; further extensions to the northeast and southeast represent priority targets for further growth with step-out drilling commencing shortly.”
