TechGen Metals has confirmed a major extension of high-grade copper-gold mineralisation at its Red Devil Zone within the Blue Devil Project in WA, setting the stage for imminent maiden drilling.
- Red Devil shear zone extended to 1.8 km with high-grade rock chips
- Peak assays include 42.6% copper and 4.56 g/t gold
- Maiden drilling campaign ready with approvals and heritage surveys completed
- Strong geophysical targets support scale potential at Blue and Red Devil
- Drilling will be the first-ever test of these undrilled copper-gold systems
High-Grade Copper-Gold Zone Extended Ahead of Drilling
TechGen Metals Limited (ASX:TG1) has unveiled a significant advance at its 100%-owned Blue Devil Copper-Gold Project in Western Australia, with new rock chip assays extending the high-grade Red Devil shear zone to approximately 1.8 kilometres. This extension comes just ahead of the company’s maiden drilling campaign, which will be the first-ever test of both the Red Devil and Blue Devil targets.
The standout rock chip results include peak copper grades of 42.6% and gold assays up to 4.56 grams per tonne, collected from a structurally controlled gossanous zone rich in iron and quartz. Nine out of fourteen samples from the main outcrop area returned copper above 1%, underscoring the strength and continuity of the mineralised system at surface.
Compelling Geophysical and Geochemical Support
Red Devil’s mineralisation is reinforced by a high-intensity Induced Polarisation (IP) chargeability anomaly, measuring 30-35mV/V within a broader zone of ~20mV/V, situated 175 to 225 metres below surface with a vertical thickness around 300 metres. This IP target is more than three times background levels and aligns with high resistivity basement units, highlighting a robust geophysical footprint for copper-gold mineralisation.
Meanwhile, the Blue Devil target features three strong airborne electromagnetic (EM) conductors coincident with a magnetic intrusion and multiple copper-gold geochemical anomalies, including key pathfinder elements critical for orebody formation. These geophysical signatures position Blue Devil as a highly prospective target for intrusion-related copper-gold deposits.
Drill-Ready with Approvals and Heritage Surveys Complete
TechGen has completed all necessary earthworks, Programme of Work approvals, and heritage surveys with Traditional Owners, clearing the path for immediate drilling. The maiden campaign will mobilise drill contractors to test these two standout targets, with assay results expected to provide the first subsurface insights into the scale and grade continuity of the mineralisation.
Managing Director Ashley Hood emphasised the significance of the new assays, stating, "Extending the mineralised trend to approximately 1.8 kilometres immediately ahead of our maiden drilling is exactly the type of result we were hoping to see. This target remains completely undrilled despite exceptional historical surface grades and combined with new compelling geophysical targets."
Targeting Multiple Mineralisation Styles in a Prospective Region
Located in the Halls Creek Orogen of the East Kimberley region, the Blue Devil Project covers 195 square kilometres and is considered prospective for multiple styles of intrusion-related mineralisation, including porphyry copper-gold, iron-oxide copper-gold (IOCG), intrusion-related gold, and skarn deposits. An external independent geochemist has supported the potential for these deposit types based on the geophysical and geochemical data.
With no prior drilling at either Red Devil or Blue Devil, TechGen is pioneering modern exploration techniques across the project, combining geological mapping, rock chip sampling, IP geophysics, and airborne EM surveys to build a compelling case for large-scale copper-gold mineralisation.
The upcoming drilling program is a critical catalyst for the company, expected to deliver the first definitive test of these targets and potentially unlock significant value for shareholders.
Bottom Line?
TechGen’s maiden drilling at Blue Devil and Red Devil will be pivotal in validating the high-grade surface results and geophysical targets, setting a clear marker for the project’s potential scale and economic viability.
Questions in the middle?
- Will maiden drilling confirm the continuity and depth extent of the high-grade copper-gold mineralisation?
- How might the distinct geophysical signatures at Blue Devil and Red Devil translate into resource scale and grade?
- What exploration strategies will TechGen pursue if initial drilling confirms significant mineralisation?
