Blue Devil Project Shows Large Conductors at 200m Depth with 50.5% Cu Rock Chips

Groundbreaking Geophysical Insights at Blue Devil

TechGen Metals Limited has taken a significant leap forward in its exploration efforts at the Blue Devil Project in Western Australia, unveiling compelling geophysical targets from its first-ever airborne electromagnetic (AEM) and magnetics survey. Utilizing the cutting-edge 12.5Hz TargetEM system, flown for the first time in Australia, the survey has delineated large, deep-seated bedrock conductors that could signal substantial copper and gold mineralisation.

The Blue Devil Project, situated within the highly prospective Paleoproterozoic Halls Creek Orogen and Neoproterozoic Wolfe Basin, is already known for historic high-grade copper and gold rock chip results, with samples reaching up to 50.5% copper and 18 grams per tonne gold. These new geophysical findings add a crucial layer of data, highlighting three distinct EM anomaly zones, BDW (Western), BDE (Eastern), and BDN (Northern), each associated with strong conductive signatures at depths around 200 metres.

Structural Controls and Magnetic Intrusions

The EM conductors are spatially correlated with major fault structures and are seen to wrap around a significant ovoid magnetic intrusion modelled between 100 to 400 metres beneath the surface. This magnetic feature is interpreted as a probable intrusion that may have acted as a source for mineralising fluids, a hallmark of several world-class copper-gold deposit types including porphyry, IOCG, and skarn systems.

Previous limited rock chip sampling near these conductors has yielded encouraging grades, such as 12.3% and 5.81% copper and gold values exceeding 6 grams per tonne. The coincidence of these high-grade surface samples with the newly identified geophysical anomalies strengthens the case for the presence of substantial mineralisation at depth.

First Mover Advantage with Advanced Technology

TechGen’s Managing Director Ashley Hood emphasised the strategic advantage of deploying Australia's most advanced airborne EM technology at Blue Devil. The 12.5Hz TargetEM system offers faster, deeper, and more accurate data acquisition, enabling the company to pinpoint priority targets with greater confidence and efficiency. This positions TechGen as a pioneering explorer in a challenging terrain often described as an exploration 'elephant field', areas known for hosting significant undiscovered mineral systems.

While historical geochemical and geological data have hinted at the project’s potential, these new geophysical results provide a fresh and robust framework for targeted drilling and further exploration. The integration of multiple data sets, geophysics, structural geology, and surface geochemistry, creates a compelling narrative for Blue Devil’s prospective copper and gold systems.

Looking Ahead: Exploration and Testing

With these promising targets now defined, TechGen is poised to advance to the next phase of exploration, which will likely include detailed field reconnaissance, further sampling, and drilling to test the depth and extent of the identified anomalies. The company’s approach exemplifies a modern exploration strategy that leverages technological innovation to unlock value in underexplored regions.

As the Blue Devil Project moves from geophysical modelling to tangible testing, market watchers and investors will be keenly observing how these targets translate into mineral resources. The combination of historic high-grade surface results and state-of-the-art geophysics sets a high bar for what could be a transformative discovery in Western Australia’s mineral landscape.
