TechGen Metals has unveiled promising assay results from its recent drilling at the Mt Boggola Project, revealing significant copper, lead, silver, and polymetallic mineralisation that supports further exploration.
- High-grade lead and silver intersected in diamond drilling
- Significant copper mineralisation near surface in RC pre-collars
- Multiple anomalous polymetallic zones identified
- Banded iron formation explains geophysical anomalies at MB4
- Follow-up drilling planned to target high-grade copper zones
High-Grade Lead and Silver Confirmed at Depth
TechGen Metals Limited (ASX:TG1) has reported compelling assay results from its recently completed drilling program at the Mt Boggola Project in Western Australia. The standout intercept came from diamond drilling at the MB4 target, where a narrow but high-grade vein returned 0.18 metres at 5.68% lead (Pb) and 49.7 grams per tonne (g/t) silver (Ag) from 216.67 metres. Visible galena mineralisation was observed, underscoring the polymetallic nature of the system.
Copper Mineralisation Near Surface Supports Broader Potential
In addition to lead and silver, the drilling intersected significant copper mineralisation in the reverse circulation (RC) pre-collars at both MB1 and MB4 targets. Notably, hole MBDD003 at MB4 delivered a 20-metre intersection averaging 1.14% copper (Cu) from just 22 metres depth, while MBDD001 at MB1 returned 4 metres at 1.04% Cu from 9 metres. These shallow copper zones coincide with malachite mineralisation logged onsite, indicating oxidised copper near surface.
Polymetallic System with Multiple Anomalous Zones
Beyond the high-grade veins, the program identified multiple zones of anomalous polymetallic mineralisation exceeding 0.1% for copper, lead, and zinc. The presence of banded iron formation at depth in hole MBDD003 explains the magnetic anomalies detected in geophysical surveys, providing a geological framework for the mineralisation. The IP chargeability anomalies at MB1 and MB4 are interpreted to be related to pyrite with weak copper, lead, and zinc mineralisation.
Strategic Follow-Up Targets Include Historical Sadlers Prospect
TechGen's Managing Director Ashley Hood emphasised the integrated nature of the results, highlighting that the polymetallic system is structurally controlled with mineralisation hosted in primary sulphides at depth and oxidised zones near surface. The company plans to refine structural interpretations through an independent geological review, which will guide targeted geophysical surveys and follow-up RC drilling. Among the priorities is the Sadlers Prospect, adjacent to Mt Boggola, where historic Newcrest drilling returned 9 metres at 1.86% copper from 47 metres, situated along strike from TechGen's recent 20-metre copper intercept.
Exploration Context and Next Steps
The Mt Boggola Project covers 458 square kilometres across four exploration licences within the Proterozoic-aged Ashburton and Edmund Basins, regions with a long history of base and precious metals exploration. TechGen completed three drill holes totaling 1,109 metres, combining RC pre-collars with diamond core tails, with most core samples assayed. While some core intervals remain unassayed, the current results provide a strong foundation for further work.
Future exploration will focus on expanding the high-grade copper zones down dip and along strike, refining vectors toward wider and richer mineralisation, and integrating geophysical data to prioritise targets. This approach aims to unlock the full potential of what appears to be a fertile polymetallic system with multiple metals of interest.
Bottom Line?
TechGen’s latest drilling at Mt Boggola has confirmed a polymetallic system with promising high-grade zones, setting the stage for targeted follow-up that could clarify the project's resource potential.
Questions in the middle?
- How will the unassayed diamond core intervals impact the overall grade and continuity of mineralisation?
- What structural controls will the independent geological review reveal to better target high-grade zones?
- Can follow-up drilling at Sadlers Prospect confirm and extend the historic copper intercepts along strike?
