Untested Soil Anomaly and No Drilling Pose Exploration Risks for TechGen Metals

New Gold Anomaly Revives Interest in Dalgaranga

TechGen Metals Limited (ASX:TG1) has spotlighted a fresh 2.5-kilometre-long gold soil anomaly at its Dalgaranga Gold Project in Western Australia, a target that has sat dormant since 1997. The Western Reefs Target, located in the project’s northwest, recorded peak soil gold values of 22 parts per billion (ppb) yet has never been followed up with exploration. Sitting just 8 kilometres from Ramelius Resources’ Dalgaranga processing plant, this soil anomaly lies within a prolific gold corridor that has seen surprisingly limited modern exploration beyond known deposits.

The Western Reefs anomaly is particularly intriguing because it straddles a contact zone between mafic gabbro and Monzogranite intrusions, a geological setting considered favourable for gold mineralisation. This discovery adds a new dimension to TechGen’s exploration pipeline, complementing earlier identified targets along the Karbah Shear Zone, a structure that hosts Ramelius’s 2.97 million ounce Dalgaranga deposit and Westgold Resources’ Big Bell mine.

High-Grade Rock Chips Signal Untapped Potential

Recent rock chip sampling has delivered encouraging assay results near the historic Armstrong Prospect, 1.2 kilometres northeast of the old WMC Armstrong workings. Among 35 samples collected, gold grades peaked at 6.07 grams per tonne (g/t) and 3.21 g/t from quartz veins, while arsenic levels reached an eye-catching 19.4%. The arsenic-rich brecciated and faulted rocks are interpreted as surface expressions of the Karbah Shear Zone, suggesting a significant gold system may lie at depth.

Despite the historic Armstrong Pit having been mined for just over 100 tonnes at 2.5 g/t gold, no drilling has ever been conducted at this prospect or the newly identified Western Reefs target. This lack of drilling underscores the potential for TechGen to unlock value through first-pass testing of these walk-up targets later this year.

Geophysical Surveys Target VHMS and Structural Controls

To complement the geochemical findings, TechGen has commenced a moving loop electromagnetic (MLEM) survey over a high-priority southern target area that exhibits coincident gold and base metal soil anomalies. This target is prospective for Volcanic-Hosted Massive Sulphide (VHMS) mineralisation, which typically manifests as conductive massive sulphide lenses detectable by EM methods. The survey comprises seven north-south traverses aimed at delineating conductors suitable for immediate drill testing.

Further enhancing the geological understanding, a detailed airborne magnetic and radiometric survey is scheduled to begin in June. With 100-metre line spacing, this survey will refine structural and lithological interpretations, particularly focusing on controls along the Karbah Shear Zone. These geophysical datasets are expected to sharpen drill targeting across the project’s multiple priority zones.

Strategic Positioning in a Proven Gold District

Dalgaranga’s location within the Archean Dalgaranga Greenstone Belt places TechGen in a well-endowed gold province. The project adjoins Ramelius Resources’ Dalgaranga Gold Project, which boasts a 2.97 million ounce resource grading 5.61 g/t gold, and is near the Big Bell Gold Mine, with 2.6 million ounces at 1.7 g/t gold. The recent identification of untested soil anomalies and high-grade rock chips adds to TechGen’s growing portfolio of targets in this proven corridor.

TechGen’s Managing Director, Ashley Hood, emphasised the significance of these findings: “Major gold potential has been unlocked with new high-priority targets identified.” He highlighted the Western Reefs anomaly’s geological setting and the arsenic-rich gold system northeast of Armstrong as “highly encouraging” for future drilling.

These developments build on the company’s recent momentum across its Western Australian projects, including promising copper-gold results and advancing drilling plans at other sites, as reported in recent updates. The integration of geophysical surveys and planned drilling at Dalgaranga could provide a clearer picture of the project’s resource potential in the coming months.
