Missed by 20 Metres: Can TechGen Unlock Mt Boggola’s Hidden Mineralisation?

Exploration Breakthrough at Mt Boggola

TechGen Metals Limited has provided a significant update on its 100% owned Mt Boggola Project in Western Australia, spotlighting new advances in geophysical modelling that could reshape the understanding of this copper-gold-antimony prospect. Located 60 kilometres south of Paraburdoo, the project spans nearly 450 square kilometres across the Ashburton and Edmund Basins, regions known for their mineral potential.

The company’s latest work employs sophisticated 3D inversion modelling of induced polarization (IP) geophysical data, which has unveiled two compelling chargeability anomalies, dubbed MB1 and MB2. These targets exhibit chargeability levels more than three times background values, indicating the presence of sulphide mineralisation potentially rich in copper, gold, and antimony.

Historical Drilling Reinterpreted

Intriguingly, historical drilling by Newcrest Mining in the early 1990s, which included reverse circulation and diamond drilling, fell just short of intersecting the core of the MB1 target by 10 to 20 metres. Despite this, several drill holes logged primary sulphides such as chalcopyrite, pyrite, and arsenopyrite near their termini, suggesting mineralisation is present but previously undrilled. Notably, antimony was not assayed in these earlier programs, leaving a gap in the historical data.

Rock chip sampling within these target areas has yielded impressive results, with MB1 samples reaching up to 10.5% copper and MB2 samples peaking at 32.6% copper, alongside 48.8 grams per tonne gold and 3.92% antimony. These high-grade surface assays reinforce the potential for significant mineralisation beneath.

Next Steps, Heritage Surveys and Drilling

TechGen has proactively booked heritage clearance surveys for the MB1 and MB2 areas, a critical step given the project’s location within native title lands governed by multiple Indigenous agreements. The company has also submitted a Program of Work for drilling, aiming to test these newly defined targets from existing drill pads, which should streamline access and reduce environmental disturbance.

Additional IP geophysical surveys are planned to extend coverage westward and over other promising zones identified by Northern Star Resources’ earlier geochemical work. These surveys will help refine drill targets and potentially uncover further mineralised zones associated with interpreted magnetic intrusions.

Strategic Implications

TechGen’s integration of modern 3D geophysical techniques with historical data and surface sampling exemplifies a methodical approach to exploration that could unlock value in underexplored regions. The proximity of high-grade rock chips and sulphide mineralisation to the chargeability anomalies bodes well for the upcoming drilling campaign, which will be closely watched by investors and analysts alike.
