The upcoming drilling programme will test three compelling DeGrussa-style targets which have been identified by both a fixed-loop electromagnetic (FLEM) ground survey and a heliborne EM survey (GTE ASX Announcement
The FLEM survey identified three isolated bedrock conductors which are interpreted to be related to sulphide mineralisation. The conductors were modelled between only 80 - 190m below surface, positioned along a government mapped contact between a siltstone-shale and boulder conglomerate- sandstone units of the Yelma Formation within the
Their prospectivity has been significantly enhanced by geological mapping and modelling which suggests the conductors have potential to be blind DeGrussa-style volcanichosted massive sulphide targets (VMS).
"Geological mapping completed by our team found the targets are located in a geological setting expected for a DeGrussa style copper-gold deposit and share many other key geological characteristics.
"The targets are modelled as sitting between 80m and 190m below surface and their highly compelling prospectivity is supported by anomalous surface sampling results with assays grading up to 0.19 per cent copper and 0.15gpt gold, indicative of a fertile mineral system".
A heritage clearance has been completed and report received for work to commence. Government Programme of Works (POW) has been approved, with a native vegetation clearing permit currently being assessed. Great Western anticipates the drilling programme at Fairbairn that will test each of the three targets will commence

Further definition of the Oval and Oval South targets was completed by a joint venture between Great Western and Sandfire (ASX:SFR), where Sandfire spent
Sandfire completed an Airborne Gravity Gradiometry (AGG) in 2022, with the AGG survey defining discrete gravity highs at Oval and Oval South, that overlayed near perfectly with the VTEM anomalies (Figure 4*). The coincident gravity and EM anomalies were interpreted as potential buried bodies of metal rich sulphide mineralisation (GTE ASX Announcement
