Great Western Exploration is set to drill six promising copper-gold targets at its Juggernaut prospect, aiming to unlock a volcanic hosted massive sulphide (VHMS) mineral system akin to nearby DeGrussa.
- Six distinct VHMS copper-gold drill targets identified at Juggernaut
- Targets show strong geological, geochemical, and structural indicators
- Located 70km from established DeGrussa and Monty deposits
- Drilling to commence post-Oval project with most approvals secured
- Potential for a clustered VHMS copper-gold camp discovery
Exploration Momentum Builds at Juggernaut
Great Western Exploration (ASX – GTE) has announced plans to drill six copper-gold targets within its Juggernaut prospect, part of the broader Yerrida North Project in Western Australia. Positioned roughly 70 kilometres southeast of the renowned DeGrussa and Monty VHMS deposits, Juggernaut is shaping up as a highly prospective volcanic hosted massive sulphide system.
A Cluster of Targets with Strong Geological Footing
The six targets, Archer, Falconer, Seymour, Smith, Howard, and Palmer, are each defined by unique stratigraphic, structural, and geochemical signatures. Great Western’s interpretation suggests these targets represent a typical VHMS camp, where multiple deposits cluster around a volcanic vent system. This is supported by broad lead-zinc and copper soil anomalies, significant rock-chip assay results, and detailed geological mapping revealing sedimentary and volcanic units indicative of a deep seafloor environment.
Strategic Location and Structural Insights
Juggernaut’s geological setting within the Killara Formation, considered equivalent in age and composition to the DeGrussa Formation, adds weight to the prospectivity. Structural modelling indicates the rocks formed in a rift regime, a known setting for VHMS mineralisation. The presence of a lag copper anomaly and mapped volcanic textures further bolster the case for preserved copper-gold mineralisation at depth.
Drilling Plans and Approvals
Drilling at Juggernaut is scheduled to follow the completion of the ongoing program at the Oval project. Access approvals have been secured for five of the six targets, with the final approval expected in the March 2026 quarter. This sequencing underscores Great Western’s methodical approach to advancing its portfolio, leveraging early successes to build momentum.
Implications for Great Western and the Region
If drilling confirms the interpreted VHMS mineralisation, Juggernaut could significantly enhance Great Western’s resource base and position in the Yerrida Basin, a region gaining attention for its copper-gold potential. The proximity to DeGrussa, one of Australia’s most productive VHMS deposits, offers a compelling analogue and a benchmark for success.
Bottom Line?
Juggernaut’s upcoming drill campaign could be a defining moment for Great Western’s copper-gold ambitions in the Yerrida Basin.
Questions in the middle?
- Will drilling confirm the presence of high-grade VHMS mineralisation at Juggernaut?
- How might Juggernaut’s discoveries impact Great Western’s valuation and exploration strategy?
- What are the timelines and expected milestones for assay results and resource updates?
