Advancing the Kalgoorlie Nickel Project: Infill Drill Program and Definitive Feasibility Study Initiatives
Tajha Pritchard

Ardea Resources Limited (Ardea or the Company) is pleased to announce the commencement of the Kalgoorlie Nickel Project (KNP) - Goongarrie Hub Definitive Feasibility Study (DFS) on 1 May 2024. Integral to the DFS is the Infill Drill program, which has already begun (see Figure 1).
The primary objective of the Infill Drill program is to upgrade the nickel-cobalt laterite resources to the Measured Mineral Resource category for the initial five-year open pits. This program entails 888 Reverse Circulation (RC) drill holes covering a total of 51,745 meters, spaced at 40x40 meters as recommended by SRK to enhance the definition of Measured Mineral Resources.
Kennedy Drilling, renowned for their extensive experience in drilling nickel-cobalt laterite deposits within the Goongarrie Hub, is executing the Infill Drill program. RC drilling activities have commenced at the Big Four nickel-cobalt deposit, with plans to drill 16,215 meters. Currently, one RC rig is operational, and additional rigs are scheduled to join the site by September 2024.
Ardea’s wholly owned subsidiary, Kalgoorlie Nickel Pty Ltd (KNPL), along with selected contract geologists, are overseeing the program. Additional support staff, including a newly appointed HSE Manager, are being recruited to assist in the smooth execution of operations.
The entire Infill RC drill program across the Goongarrie Hub is projected for completion by the end of CY2024. Results from these drills will contribute to an updated Mineral Resource Estimate (Measured category) for the initial five-year open pits, bolstering confidence in the existing nickel laterite resources, particularly during the payback period.
As part of the DFS, further drill programs are planned for geotechnical assessments and hydrogeological testing. Additionally, diamond core drilling will be conducted to provide metallurgical samples at bench scale and validate historical RC results. The commencement of these programs is contingent upon receiving approvals (programs of work) from DEMIRS and finalizing the drill design.
