3D Seismic Identifies Growth Potential at Hillside

Rex Minerals Hillside project is one of Australis’s largest undeveloped open pit copper projects situated on the Yorke peninsula in South Australia. The copper-gold resource is within the eastern Gawler Craton which hosts other large copper deposits such as Olympic Dam, Prominent Hill and Carrapateena.

Geological interpretation from 3D seismic provided valuable insight into the key features that control the copper mineralisation at Hillside. HiSeis’ automated technology products FAULT-MOD and SEISOMICS were used to aid interpretation.

This work identified several new key target areas, numerous faults in the host rock and a large body potentially representing the intrusive “source rock”. Drilling has since validated the seismic model and identified seismic signatures of known mineralisation.

Automated fault modelling (FAULT-MOD) used to understand impact on mineralisation at Hillside.

“This recent 3D seismic survey could be a game changer for Rex…the information obtained shows features which are known to be associated with mineralisation extending well away from the existing drilling, confirming potential extensional drill targets.” ASX June, Oct 2022
