Miramar Resources Limited advised that results from analysis of end of hole samples from aircore drilling at the Company's 100%-owned Whaleshark Project have increased the potential for the Project to host iron oxide copper gold mineralisation. The Whaleshark Project is located approximately 40km east of Onslow, in the Ashburton region of Western Australia, and is characterised by a large folded Proterozoic banded iron formation and granite complex under approximately 100m of Cretaceous Carnarvon Basin sediments. The Company believes there is potential for discovery of a large IOCG deposit at Whaleshark.

End of hole samples from the 2022 aircore drilling campaign were analysed for a multi-element suite, including IOCG pathfinders and elements diagnostic of hydrothermal alteration. WSAC010 (80m), at the northern edge of the drill pattern, intersected strongly elevated copper (435.5ppm), cobalt (888.9ppm), silver (7.71g/t) along with anomalous tungsten and rhenium. WSAC010 returned the highest copper and cobalt results from Whaleshark to date and overlies a 500m x 750m gravity anomaly within the granite intrusion which is bisected by a NW trending structure.

According to publicly available information, the large Ernest Henry IOCG deposit shows similar coincident copper and cobalt anomalism at the unconformity directly above the deposit. Hole WSAC035 (67m) intersected 165ppm Cu and 0.16g/t Au adjacent to the same basement structure. EOH results for sodium (Na) and potassium (K) show coherent anomalism suggesting the presence of sodic and potassic alteration in the basement rocks, which is a key signature of significant IOCG mineralisation.

The magnitude of the Na and K anomalism is also comparable to the Ernest Henry data. Importantly, the implied potassic alteration, usually proximal to IOCG mineralisation, is adjacent to the highest copper and gold results.
