Geophysical Surveys Target High-Grade Copper and Gold at Two Strategic Projects
TechGen has initiated a new Induced Polarisation (IP) geophysical survey at its Blue Devil Project, specifically targeting recently discovered high-grade copper-gold mineralisation. Concurrently, the company has completed a second stage IP survey at Mt Boggola where rock chip sampling has also been recently conducted.
The timing of these exploration activities by Techgen Metals Ltd is strategic as the company prepares for a heritage survey scheduled for October 21, which will pave the way for potential drilling of identified targets.
"These parallel exploration programs at Blue Devil and Mt Boggola represent a systematic approach to validating the exceptional high-grade copper and gold potential we've identified," said Ashley Hood, Managing Director of TechGen Metals.
Mt Boggola: Compelling Targets Emerge from Completed IP Survey
The Mt Boggola Project, located 60km south of Paraburdoo, has seen the completion of a stage 2 IP survey, with data modelling and processing currently underway. This survey covered an area to the west of the previously completed stage 1 survey, including previous Newcrest Mining drill holes PB14 and PB15, both of which had primary copper sulphide (chalcopyrite) logged toward the bottom of the holes.
The first stage IP survey identified two significant chargeability anomalies (MB1 and MB2) that have never been drill tested. Historical drilling by Newcrest Mining in 1991 stopped short of reaching these high-chargeability zones, leaving them completely unexplored.
Recent rock chip sampling of copper gossans near these targets has been completed, with 18 samples now at the laboratory awaiting analysis.
Historical exploration at Mt Boggola by Northern Star Resources between 2015-2018 identified significant values in soil sampling:
- Copper: up to 1,070 ppm
- Gold: up to 60 ppb
- Arsenic: up to 240 ppm
- Lead: up to 593 ppm
Even more impressive were rock chip results from the same area, which returned exceptional grades including:
- Gold: 48.8 g/t, 34.5 g/t, 7.73 g/t, 4.82 g/t & 3.47 g/t
- Copper: 27.8%, 20.3% & 16.75%
- Antimony: 3.92%, 3.51% & 2.27%
- Lead: 3.72%, 1.38% & 1.04%
Blue Devil: IP Survey Targeting Exceptional High-Grade Copper Discovery
At the Blue Devil Project, located 40km northeast of Halls Creek, an IP geophysical survey has commenced over an area where recent exploration activities by Techgen Metals Ltd identified extraordinary high-grade copper gossan outcrops. This survey aims to define potential drill targets in addition to the already identified 2.75km long EM conductor and intrusion targets.
The impressive rock chip results from Blue Devil include:
- Copper: 52.3%, 22.6% & 21%
- Gold: 5.35 g/t & 1.84 g/t
These samples were collected along an east-west quartz structural corridor spanning approximately 2km. The exceptional copper grade of 52.3% is particularly noteworthy, as it represents nearly pure copper mineralisation at surface.
Understanding Induced Polarisation (IP) Surveys
IP geophysics is a powerful exploration tool that measures the chargeability of subsurface materials. This technique is particularly effective at detecting disseminated sulphide minerals that often host copper, gold, and other valuable metals.
When an electrical current is passed through the ground, certain minerals like copper and iron sulphides temporarily store electrical energy (become "charged"). The IP survey measures how long this charge is retained after the current is switched off. Areas with higher chargeability often correspond to zones of concentrated sulphide mineralisation, which can indicate potential mineral deposits.
For investors, IP anomalies represent potential drill targets where mineralisation may be concentrated. The stronger the chargeability response, the greater the potential concentration of sulphide minerals, though drilling is ultimately required to determine economic value.
Strategic Positioning and Future Plans
TechGen Metals is strategically positioned with these two copper-gold projects in recognised geological provinces of Western Australia. The Blue Devil Project, covering 195km² across three exploration licenses, presents what the company describes as "an attractive, first-mover opportunity" within the Halls Creek Orogen. Meanwhile, the Mt Boggola Project encompasses a substantial 449km² across three exploration licenses in the Proterozoic-aged Ashburton and Edmund Basins.
The company's near-term plans include:
- Completing analysis and interpretation of the IP survey data at both projects
- Conducting the scheduled heritage survey on October 21
- Determining drill targets based on geophysical and surface sampling results
- Planning drill programs to test the identified targets
Investment Perspective
TechGen Metals presents an interesting opportunity for investors seeking exposure to early-stage copper and gold exploration. The company's exploration activities by Techgen Metals Ltd demonstrate several positive attributes:
-
High-Grade Potential: Surface samples showing exceptional copper grades over 50% and gold grades over 5 g/t indicate the potential for significant mineralisation.
-
Systematic Exploration Approach: The company is methodically building its understanding of these projects through geophysics, sampling, and geological interpretation before drilling.
-
Strategic Commodities: Copper and gold are both in high demand, with copper particularly vital for electrification and renewable energy infrastructure.
-
Unexplored Targets: The identification of IP anomalies that have never been drill-tested creates genuine exploration upside.
-
Historical Context: Previous work by major mining companies like Northern Star and Newcrest provides valuable historical data and validation of the prospectivity.
With a heritage survey scheduled for October 21 and data processing underway, investors can expect regular news flow as the company advances toward potential drilling. The exceptional grades in surface samples provide encouragement, though further exploration activities by Techgen Metals Ltd are needed to determine if these grades extend to depth and have economic potential.
For investors interested in junior explorers with high-grade copper-gold potential, TechGen Metals warrants close attention as it advances these promising Western Australian projects.
