Discovery Doubles Drill Target Portfolio with Exceptional Surface Grades
TechGen Metals Limited has transformed its Mt Boggola drilling program event into a compelling multi-target drilling opportunity after completing a second-stage induced polarisation (IP) survey. Furthermore, the company identified two additional high-chargeability anomalies, bringing the total to four distinct drill targets (MB1-MB4). These targets are supported by exceptional surface copper grades up to 43.1% and gold values reaching 7.31g/t.
The Mt Boggola Project, located 60km south of Paraburdoo in Western Australia, covers 449 km² across three exploration licences. In addition, it targets shear zone hosted and intrusive-related copper-gold-antimony mineralisation.
Significantly, TechGen is the first company to conduct comprehensive geophysical surveys across this project area. This represents a notable achievement, despite previous exploration by industry heavyweights including Newcrest Mining, Goldfields, and Northern Star Resources.
Key Highlights from Latest Campaign
| Target | Peak Copper | Peak Gold | Chargeability | Depth to Target |
|---|---|---|---|---|
| MB1 | 31.7% | 0.117g/t | >34 mV/V (3x background) | 75-100m |
| MB2 | – | – | >28 mV/V | 100-125m |
| MB3 | 43.1% | 3.44g/t | >25 mV/V | 100-150m |
| MB4 | 16.4% | 7.31g/t | >25 mV/V | 150-175m |
The recent rock chip sampling program returned seven samples exceeding 10% copper. Moreover, the highest grade of 43.1% came from sample MB275 at target MB3.
Gold mineralisation proved equally impressive, with six samples above 1g/t. Consequently, a peak result of 7.31g/t was achieved from target MB4.
Understanding IP Geophysics: The Technology Behind the Discovery
Induced Polarisation (IP) geophysics represents one of the most effective exploration tools for detecting sulphide mineralisation beneath the surface. The technique works by injecting electrical current into the ground and measuring how long the subsurface takes to "discharge".
Essentially, this process detects the chargeability of buried materials. Sulphide minerals, which commonly host copper and gold in this geological setting, exhibit high chargeability signatures. Furthermore, these signatures stand out clearly from background rock.
At Mt Boggola, the four targets show chargeability levels 2-3 times higher than background readings. This indicates substantial sulphide concentrations at relatively shallow depths.
Why IP Anomalies Matter for Investors
For investors, IP anomalies provide high-confidence drill targets because they directly detect the types of minerals being sought. Unlike other exploration methods that provide indirect evidence, IP essentially "sees" the sulphides that typically contain economic copper and gold grades.
Additionally, the shallow depths to these targets (75-175 metres) suggest cost-effective drilling programmes with quick results. This represents a significant advantage for the Mt Boggola drilling program event Techgen Metals Ltd.
Glossary of Key Terms
- Chargeability: Measure of how well subsurface materials hold electrical charge
- Resistivity: Measure of how well materials conduct electricity
- Gossan: Weathered, iron-rich surface expression of underlying sulphide deposits
- Malachite: Green copper carbonate mineral indicating copper mineralisation below
Strategic Positioning Around Magnetic Intrusion Creates Multiple Opportunities
The four IP targets align strategically around a prominent magnetic intrusion that appears central to the mineralising system. Target MB4 sits partially coincident with this intrusion. However, MB1, MB2, and MB3 are positioned at varying distances from the intrusive body.
This spatial relationship suggests a classic intrusion-related copper-gold system. In this model, the magnetic body served as the heat and fluid source for mineralisation.
The geological interpretation indicates that surface copper and gold occurrences result from hydrothermal fluids emanating from the magnetic intrusion. These fluids are being channelled along structural controls including shear zones. Consequently, this model supports the potential for primary copper-gold mineralisation at depth across all four target areas.
"The source of the observed surface mineralisation and IP targets is interpreted to be the magnetic intrusion that is coincident with the newly identified MB4 target. Targets MB1, MB2 and MB3 are located at varying distance from the intrusion and the hope is for primary copper and gold mineralisation to be associated with these targets through structural controls."
Managing Director Ashley Hood provided this interpretation of the Mt Boggola drilling program event.
What Makes This Discovery Significant?
The discovery doubles TechGen's drill target portfolio whilst maintaining exceptional grade quality across all targets. Furthermore, the systematic approach has revealed a target-rich environment that previous explorers failed to properly evaluate.
Each target offers distinct characteristics that enhance the overall project value. For instance, MB1 shows the highest chargeability signature, whilst MB4 combines the best gold grades with direct association to the magnetic intrusion.
Drilling Programme Awaits Final Approvals with Strong Technical Foundation
TechGen has positioned the Mt Boggola Project for immediate drilling following completion of heritage surveys. In addition, the company awaits receipt of Department of Mines approvals.
The company maintains optimism for drilling commencement before year-end. All four targets are now fully defined and supported by compelling geochemical and geophysical evidence.
Technical Validation Summary
| Supporting Evidence | Details |
|---|---|
| Previous Work | Northern Star soil geochemistry defined Cu-As-Au-Pb anomalies |
| Surface Grades | 18 rock chips with Cu grades 0.066-43.1%, Au grades <0.005-7.31g/t |
| Geophysical Definition | 7.5km of IP surveying across four 200m-spaced lines |
| Historical Context | Newcrest drilling PB14 & PB15 intersected chalcopyrite but failed to reach IP target depths |
| Shallow Targets | All anomalies commence within 175m of surface |
The discovery that previous Newcrest drilling failed to reach the IP target depths adds significant confidence to the upcoming programme. Historical holes PB14 and PB15 encountered trace chalcopyrite in their lower portions. However, they may have been testing only the upper margins of the mineralised system.
Why Historical Work Validates Current Targets
Previous explorers focused on different methodologies that failed to identify the full extent of mineralisation. Consequently, TechGen's comprehensive IP survey has revealed the true potential of this system.
The Mt Boggola drilling program event Techgen Metals Ltd represents the first systematic evaluation of these high-chargeability anomalies.
