TechGen Metals has cleared the final regulatory hurdle to begin maiden diamond drilling at its Blue Devil Project in WA, targeting large-scale copper-gold systems with government co-funding easing exploration costs.
- Programme of Work approved for maiden drilling
- Blue Devil target shows strong airborne EM conductors
- Red Devil target features high-intensity IP anomaly with rock chip assays up to 52.3% Cu
- WA Government Exploration Incentive Scheme co-funding secured
- Heritage surveys with Traditional Owners completed
Final Approval Unlocks Drilling at Untested Blue Devil and Red Devil Targets
TechGen Metals Limited (ASX:TG1) has received the green light to commence its maiden diamond drilling campaign at the Blue Devil Project, located 40 kilometres northeast of Halls Creek in Western Australia. This marks a critical step forward as the Company targets large-scale copper-gold mineral systems in a region that has seen limited modern exploration despite promising historic geochemical signatures.
The approved Programme of Work (POW) covers two priority targets within the 195 square kilometre project area: Blue Devil and Red Devil. Both targets are defined by cutting-edge geophysical surveys; TechGen is the first to apply modern airborne electromagnetic (EM) and induced polarisation (IP) techniques here; identifying compelling drill-ready anomalies that have never before been tested.
Blue Devil: Airborne EM Conductors Over Intrusive Body Signal Potential
Blue Devil stands out with three discrete, strong airborne EM conductors extending over 2.75 kilometres, situated approximately 150 metres above a magnetic high interpreted as an intrusive body. Airborne EM surveys typically detect only the most conductive zones, underscoring the significance of these anomalies. This geophysical signature aligns with multiple surface geochemical anomalies, positioning Blue Devil as a prime candidate for intrusion-related copper-gold mineralisation styles such as porphyry and iron oxide copper-gold (IOCG) deposits.
Red Devil: High-Intensity IP Anomaly Supported by Exceptional Surface Grades
The Red Devil target hosts a high-intensity IP chargeability anomaly with a core zone registering 30 to 35 millivolts per volt (mV/V), more than three times background levels, extending 175 to 225 metres below surface and approximately 300 metres thick vertically. This anomaly coincides with an east-west shear zone and is bolstered by rock chip samples exhibiting extraordinary copper and gold grades, including assays up to 52.3% copper and 5.35 grams per tonne gold. These grades signal the potential for high-grade mineralisation at depth.
Government Support and Heritage Engagement Enhance Project Viability
Adding to the project's momentum, TechGen has secured co-funding from the Western Australian State Government’s Exploration Incentive Scheme (EIS), which will help reduce drilling costs and improve capital efficiency. The Company also completed heritage surveys with Traditional Owners in late 2025, clearing a key social and regulatory milestone ahead of drilling.
Managing Director Ashley Hood emphasised the significance of this milestone: "These targets have never been drill-tested and have seen limited previous geophysical work. We are delighted to be the first company to test these highly prospective targets, which combine strong geophysical signatures with anomalous surface geochemistry."
Next Steps: Drilling to Define Mineralisation Potential
With permitting completed and co-funding secured, TechGen is poised to initiate drilling that will provide the first direct insights into the subsurface geology and mineralisation at Blue Devil and Red Devil. The results will be pivotal in assessing the scale and grade potential of these targets, which could significantly advance the Company’s copper-gold portfolio in Western Australia.
Bottom Line?
TechGen’s maiden drilling at Blue Devil and Red Devil will be a crucial test of geophysical and geochemical targets that could reshape its copper-gold prospects in WA.
Questions in the middle?
- Will maiden drilling confirm the scale and grade suggested by geophysical anomalies and surface assays?
- How will government co-funding influence TechGen’s exploration budget and timeline?
- What are the implications of these targets for TechGen’s broader copper-gold strategy in the Kimberley region?
