16 Impact Minerals Ltd Annual Report 2023 Review of Operations continued ABOUT THE ARKUN PROJECT Previous work by Impact across the Arkun and Beau project areas using a proprietary geophysicalgeochemical technology owned by Southern Sky Energy Pty Ltd identified 17 broad areas of interest, principally for Ni‑Cu-PGM mineralisation, for follow‑up work (ASX Release 10th June 2021). Reconnaissance soil geochemistry traverses along gazetted roads and tracks over 15 of these targets, identified 22 more specific targets for both Ni-Cu-PGM mineralisation and, for the first time in the area, lithium-caesiumtantalum pegmatites and Rare Earth Elements (REE). A number of the original targets returned anomalous soil results for more than one style of mineralisation. Targets for both Ni-Cu-PGM and lithium were identified at Beau (ASX Release 21st September 2021). Figure 12. Airborne EM survey blocks (in red) over previous roadside soil geochemistry anomalies for Ni-Cu -PGM, Li-Cs-Ta, REE and Rb (additive Z scores: see ASX Releases 8th March 2022, 27th October 2021 and 21st September 2021 for details).
