 Infill Drilling Confirms High Grade Ni-Co-Sc at Goongarrie South
Key Points
  • 249 significant intercepts (>0.5% Ni over at least 2m) recorded in 195 holes
  • High-grade intercepts include 34m at 1.75% Ni, 0.43% Co and 26m at 1.48% Ni, 0.21% Co
  • Goongarrie South confirmed as the highest-grade Ni-Co deposit within the Kalgoorlie Nickel Project
Full Summary

Ardea Resources has provided an update on the infill RC drilling program recently completed at the Kalgoorlie Nickel Project (KNP) - Goongarrie Hub as part of the ongoing Definitive Feasibility Study (DFS). The drilling program at the Goongarrie South deposit, located adjacent to the proposed processing plant, has confirmed multiple thick, continuous zones of high-grade nickel-cobalt-scandium mineralization, with many extending below the previous Pre-Feasibility Study pit shells. A total of 249 significant intercepts (>0.5% Ni over at least 2m) were recorded in 195 of the 230 RC holes drilled, with highlights including 34m at 1.75% Ni, 0.43% Co from 12m and 26m at 1.48% Ni, 0.21% Co from 22m. The results reinforce Goongarrie South as the highest-grade nickel-cobalt deposit within the broader KNP - Goongarrie Hub. Detailed geological interpretation and domain modelling is ongoing as part of the DFS, including the definition of Mineralised Neutraliser, which could support deeper optimised pit designs and provide operating and capital cost benefits in the early stages of the project's development.

Outlook

The successful identification of Mineralised Neutraliser at Goongarrie South may support deeper optimised pit designs in the DFS, potentially capturing additional nickel and cobalt units that would otherwise have been excluded from the mine plan. The presence of this Mineralised Neutraliser near the proposed process plant location also has the potential to minimise reliance on more distant resources in the early stages of the operation, providing both operating and capital cost benefits.
