TechGen Metals Mt Boggola Project Reveals Game-Changing 3D Data

TechGen Metals Reveals Game-Changing 3D Data at Mt Boggola Copper-Gold Project

TechGen Metals (ASX: TG1) has unveiled significant advancements at its 100% owned Mt Boggola Copper-Gold-Antimony Project in Western Australia, with new 3D modeling revealing that historical drilling stopped short of key targets and a heritage survey now booked to advance exploration efforts.

New 3D Modeling Reveals Historical Drilling Fell Short of High-Value Targets

In a major technical breakthrough, TechGen's enhanced 3D inversion modeling has shown that four historical Newcrest drill holes from the 1990s missed the top of the MB1 chargeability target by only 10-20 meters. The modeling has completely transformed the understanding of the project's potential compared to previous 2D cross-section images.

What makes this discovery particularly significant is that three of the four Newcrest drill holes contained primary copper sulphide mineralization (chalcopyrite), along with pyrite and arsenopyrite logged in the bottom of the holes. This strongly suggests the drilling stopped just short of potentially much larger mineralized zones.

"With the latest enhancement of the 3D inversion isosurfaces modeling completely upgrades the previous 2D cross section image," said TechGen's Managing Director, Ashley Hood. "What is most interesting and technically significant is the presence of primary copper sulphide mineralisation, chalcopyrite, along with pyrite and arsenopyrite being logged in the three deeper Newcrest drill holes."

Impressive Surface Sampling Reinforces Target Potential

Surface sampling continues to validate the potential of TechGen's IP (Induced Polarization) chargeability targets:

• MB1 Target: 18 rock chip samples exceeding 1% copper with peak values of 10.5% Cu
• MB2 Target: 11 rock chip samples all exceeding 1% copper with exceptional peak values of 32.6% Cu, 48.8 g/t Au, and 3.92% Sb

The MB1 target displays chargeability more than three times background levels (>34 mV/V vs ~10 mV/V background), covering an area of 400m × 150m with the top of the anomaly at a relatively shallow 75-100 meters depth.

Heritage Survey Booked and Drilling Preparations Underway

TechGen has secured a heritage survey for late September covering the MB1 and MB2 targets, representing a crucial step toward drill testing. Notably, the company can access and drill the MB1 target from existing historical drill pads, potentially accelerating the exploration timeline.

A Program of Work for drilling has already been submitted, positioning the company to move quickly once heritage clearance is received.

Understanding IP Geophysics: Why It Matters for Copper Exploration

Induced Polarization (IP) is a geophysical technique particularly effective at identifying disseminated sulphide minerals that often host copper, gold, and other valuable metals. The technique measures the "chargeability" of the ground—essentially how well the subsurface can hold an electrical charge.

IP surveys are especially useful for detecting disseminated sulphide deposits that may not create strong magnetic or electromagnetic signatures. When sulphide minerals are present in the ground, they create measurable electrical polarization effects that can be detected and mapped by IP surveys.

For investors, understanding the significance of IP anomalies requires some context:

• Chargeability readings: Values 2-3 times above background levels (as seen at Mt Boggola) represent significant anomalies
• Resistivity correlation: When chargeability highs coincide with resistivity lows (as at MB1 and MB2), they often indicate zones of mineralization
• Surface confirmation: When IP anomalies occur beneath areas with high-grade surface samples, they become compelling drill targets

The MB1 and MB2 targets at Mt Boggola demonstrate all three of these favorable characteristics, making them high-priority exploration targets.

Historical Context Enhances Project Potential

The Mt Boggola Project benefits from significant historical work:

• Northern Star Resources conducted detailed soil sampling between 2015-2018, identifying anomalies with peak values of 1,070 ppm Cu, 60 ppb Au, 240 ppm As, and 593 ppm Pb
• Newcrest Mining drilled 15 holes in the area in 1991, with encouraging intercepts including:
  • 2m @ 1.58% Cu & 0.48 g/t Au from 8m (PB04)
  • 4m @ 1.56% Cu from 32m (PB09)
  • 4m @ 2.32% Cu from 12m (PB13)
  • 4m @ 1.08% Cu from 36m (PB14)

Notably, 7 out of 12 Newcrest holes drilled in the Northern Star soil anomaly area intersected primary sulphide mineralization (chalcopyrite), further validating the area's prospectivity.

Additional IP Surveys to Expand Target Inventory

The company is expanding its IP survey coverage westward to include the area of drill holes PB13 and PB14 and an interpreted magnetic intrusion. This area has previously yielded exceptional rock chip samples including 48.7% Cu & 119 g/t Ag (MB69) and 17.8% Cu & 5.08 g/t Au (MB12).

Investment Potential: Multiple Catalysts Ahead

TechGen Metals is advancing a highly prospective copper-gold project with several near-term catalysts:

1. Results from the heritage survey expected by end of September
2. Completion of additional IP geophysical surveys over known mineralization
3. Potential commencement of drilling at MB1 once approvals are received
4. Expanded exploration across the broader 449 km² project area

For investors looking for exposure to copper and gold exploration, TechGen presents a compelling opportunity with near-term news flow potential and a project located in the mining-friendly jurisdiction of Western Australia.

Why Follow TechGen Metals

TechGen's Mt Boggola Project offers exceptional exploration potential based on multiple factors:

• New 3D modeling showing historical drilling stopped short of primary targets
• Extremely high-grade surface sampling (up to 32.6% Cu and 48.8 g/t Au)
• Strong IP geophysical anomalies coincident with surface mineralization
• Strategic location in the prospective Ashburton Basin of Western Australia
• Well-defined, drill-ready targets with heritage clearance in process
• Previous drilling by majors (Newcrest, Northern Star) providing valuable historical data

With copper prices forecast to rise substantially due to increasing demand from renewable energy and electric vehicles, TechGen's focus on high-grade copper-gold targets positions it well to capitalize on this macro trend.
