TechGen Metals Identifies Untested Gold and VHMS Targets at Dalgaranga Project

High-Grade Gold Target Emerges at Historic Armstrong Prospect

TechGen Metals Limited (ASX:TG1) has unveiled two compelling exploration targets at its Dalgaranga Gold Project, located in Western Australia’s prolific Archean greenstone belt. The standout is a gold soil anomaly enveloping the Armstrong Prospect, a site with historic open pit workings that produced 107 tonnes at 2.5 g/t gold in the 1980s. Rock chip sampling by TechGen has returned impressive assays up to 39.3 g/t Au, underscoring the prospect’s potential. Despite this, the area remains undrilled, representing a rare chance to test a known mineralised system in a proven gold corridor.

Discovery of a Volcanic-Hosted Massive Sulphide (VHMS) Target Adds New Dimension

Alongside the gold target, TechGen has flagged a southern soil anomaly characterised by coincident copper, zinc, and gold geochemistry over a prominent airborne magnetic and gravity feature. This signature is interpreted as a VHMS-style target, a deposit type known for hosting significant base metal mineralisation. Ground electromagnetic (EM) surveys are planned to refine this target before any drilling is undertaken. The identification of this VHMS target near Ramelius Resources’ Dalgaranga mine and Westgold Resources’ Big Bell mine situates TechGen’s project within a highly prospective mineral belt.

Strategic Location Along Karbah Shear Zone

Both targets lie along the Karbah Shear Zone, a major structural feature that hosts some of the region’s largest gold deposits, including Ramelius Resources’ Dalgaranga Gold Project (2.97 million ounces at 5.61 g/t Au) and Westgold’s Big Bell mine (2.6 million ounces at 1.7 g/t Au). The proximity; just 8km from Ramelius’s processing plant; adds logistical appeal. The soil sampling program, covering parts of exploration licences E59/3024 and E59/3059, involved 570 samples spaced mostly at 200m intervals, with denser sampling near Armstrong. This methodical approach has yielded robust targets that have not previously been drill tested, a notable gap given the area’s mineral endowment.

TechGen’s Managing Director Ashley Hood highlighted the significance of the findings: "The gold target was expected given the historic workings, but the VHMS target was a welcome surprise. Both targets are on a major shear zone that hosts significant gold mines, yet this area has never seen modern exploration." The company is preparing for field verification and further geophysical work to advance these prospects.

Next Steps and Exploration Outlook

Planned activities include detailed geological mapping, ground EM surveys to better define the VHMS target, and ultimately drilling to test both the Armstrong gold prospect and the base metal anomaly. The absence of previous drilling at these targets means TechGen is entering a relatively fresh exploration phase in a jurisdiction known for delivering high-grade discoveries. This announcement follows TechGen’s recent progress at other WA projects, including the Blue Devil copper-gold targets where licence grants and drilling approvals have been secured advances at Blue Devil Project. The Dalgaranga project’s location and initial results position it as a key focus for the company’s 2026 exploration program.

While the soil and rock chip results are encouraging, it is important to note that these are early-stage exploration findings. The economic viability of the targets remains to be demonstrated through drilling and further technical studies. Nonetheless, the combination of historic high-grade gold, a new VHMS target, and strategic positioning in a well-endowed gold belt makes Dalgaranga a project to watch.
