TechGen Metals Moves Drill Rig to Larger Blue Devil Copper-Gold Target
TechGen Metals Limited (ASX: TG1) has released a compelling exploration update from its Dalgaranga Gold Project in Western Australia, unveiling multiple new high-priority gold targets, high-grade rock chip results, and a geophysics programme already underway. The Techgen Metals Dalgaranga Gold Project new gold targets in Western Australia represent a significant step forward for a junior explorer operating on the doorstep of one of Australia's most prolific gold corridors, building out a drill-ready pipeline.
The Dalgaranga Gold Project sits 475km northeast of Perth and just 8km from Ramelius Resources' operating Dalgaranga processing plant, placing TechGen's ground squarely within one of Western Australia's most active and proven gold-producing regions. The project comprises three exploration licences — E59/3024, E59/3059, and E59/3064 — that adjoin and run along strike from Ramelius Resources' Dalgaranga Gold Project.
To put the neighbourhood into context:
| Nearby Project | Company | Resource |
|---|---|---|
| Dalgaranga Gold Project | Ramelius Resources | 2.97 Moz @ 5.61 g/t Au |
| Big Bell Gold Mine | Westgold Resources | 2.6 Moz @ 1.7 g/t Au |
| TechGen Dalgaranga Project | TechGen Metals | Exploration stage |
Both major deposits sit along the Karbah Shear Zone — a regionally significant structural corridor that also runs directly through TechGen's licences. Critically, none of TechGen's priority targets have ever been drilled.
The announcement covers four distinct and concurrent developments, each adding a new layer to TechGen's exploration story at Dalgaranga.
A review of historical exploration data has brought a previously overlooked 1997 dataset back into focus. Soil sampling conducted by Western Reefs Limited across the project's northwestern area — consisting of 1,050 samples — defines a 2.5km-long northeast-southwest trending gold soil anomaly, grading above +5 parts per billion (ppb) Au with a peak result of 22ppb Au.
No follow-up exploration of any kind has been conducted at this target since 1997. The anomaly remains open along strike and has never been drill tested. Geologically, it sits on a contact zone between a mafic gabbro and a Monzogranite intrusion — a structural and lithological setting considered highly prospective for gold.
Summary of the 1997 Western Reefs soil dataset:
| Parameter | Value |
|---|---|
| Total Samples | 1,050 |
| Peak Gold | 22 ppb Au |
| Peak Copper | 86 ppm Cu |
| Peak Zinc | 110 ppm Zn |
| Peak Arsenic | 95 ppm As |
| Anomaly Strike Length | 2.5 km |
A moving-loop ground electromagnetic (MLEM) survey has commenced over a high-priority gold and base metal soil target in the project's southern area. Seven north-south traverse lines are planned. The target is considered prospective for both gold mineralisation and Volcanic-Hosted Massive Sulphide (VHMS) style deposits, which can contain copper, zinc, lead, gold, and silver.
Conductive anomalies identified by the EM survey would represent direct walk-up drill targets — meaning any positive result converts almost immediately into a drillable opportunity.
During a recent site visit, 35 rock chip samples were collected across the project. The most significant results came from two areas:
| Sample | Au (g/t) | As (%) | Location |
|---|---|---|---|
| DR048 | 1.235 | 19.4% | Breccia/fault zone, 1.2km NE of Armstrong |
| DR049 | 0.324 | 11.25% | Breccia/fault zone |
| DR050 | 0.312 | 17.95% | Breccia/fault zone |
| Sample | Au (g/t) | Location |
|---|---|---|
| DR061 | 6.07 | Armstrong Prospect (quartz vein) |
| DR062 | 3.21 | Armstrong Prospect (quartz vein) |
The iron-quartz-arsenic breccia observed at the new northeast target — despite being partially masked by shallow cover — is interpreted by TechGen as the surface expression of a potentially significant gold system at depth.
A detailed airborne magnetic and radiometric survey at 100-metre line spacings has been booked and is scheduled to commence during June. This data will support structural and geological interpretation across the entire project area, with a specific focus on understanding mineralisation controls along the Karbah Shear Zone.
Furthermore, the survey is expected to meaningfully refine targeting ahead of planned drilling later in the year.
Managing Director Ashley Hood commented:
"Our Dalgaranga project already contains an outstanding walk-up drilling target at the historic WMC Armstrong pit that has never been drilled with planned drilling later in the year. Until drilling starts, we are continuing to identify additional drill ready targets. Major gold potential has been unlocked with new high-priority targets identified… Even more encouraging is our second target, located just 1.2km north-east of the historic Armstrong pit, highlighting the potential for along-strike extensions. The presence of iron-quartz-arsenic breccia suggests we are looking at the upper expression of a significant, highly encouraging gold system at depth. Follow-up drilling is being prioritised."
One standout feature of TechGen's rock chip results is the extraordinarily high arsenic values returned from the breccia zone — up to 19.4% arsenic — which warrants explanation for investors less familiar with gold geology.
Arsenic in gold exploration most commonly occurs as arsenopyrite (FeAsS), a sulphide mineral that frequently forms in close association with gold in orogenic (structurally controlled) and shear-zone-hosted gold deposits. In many of Western Australia's most significant gold systems, elevated arsenic is considered a direct pathfinder element — meaning it points prospectors toward gold mineralisation, even where gold grades at surface may be diluted by weathering or shallow cover.
| Term | Meaning |
|---|---|
| ppb (parts per billion) | Used for soil gold — 22ppb = 22 grams per 1,000 tonnes of material |
| g/t (grams per tonne) | Used for rock and drill sample gold grades |
| VHMS | Volcanic-Hosted Massive Sulphide — a deposit type hosting copper, zinc, gold, silver |
| MLEM | Moving Loop Electromagnetic — a ground geophysics technique detecting conductive bodies |
| Pathfinder element | A chemical element spatially associated with ore deposits, used to guide exploration |
| Shear zone | A planar zone of deformed rock, often acting as a conduit for gold-bearing fluids |
| Karbah Shear Zone | A major regional structure hosting both Dalgaranga (Ramelius) and Big Bell (Westgold) mines |
TechGen's near-term exploration schedule is well-defined and already in motion. Multiple workstreams are running concurrently, reducing idle time between data collection and target generation.
| Activity | Status / Timeline |
|---|---|
| MLEM Ground EM Survey — Southern VHMS/Gold Target | Commenced — in progress |
| Rock Chip Sampling — 35 samples across project | Complete — assays received |
| Airborne Magnetic & Radiometric Survey (100m lines) | Booked — commencing June |
| Drilling — Armstrong Prospect | Planned later in 2026 |
| Follow-up drilling — NE Breccia/Shear Zone Target | Being prioritised |
| Western Reefs Soil Anomaly — further follow-up | Under review |
Three priority targets — the Armstrong Prospect, the Western Reefs gold soil anomaly, and the southern VHMS/gold target — remain undrilled. With ground geophysics underway and airborne data incoming, the programme is building systematically toward a maiden drill campaign.
For investors evaluating the TechGen Metals Dalgaranga Gold Project new gold targets in Western Australia, several structural features of the investment case stand out.
At just 8km from Ramelius Resources' Dalgaranga processing plant, any discovery on TechGen's ground would have an immediate and credible development pathway. Junior explorer projects adjacent to operating mills with excess capacity are considered among the most capital-efficient exploration propositions in the sector.
The Karbah Shear Zone is not speculative geology — it is a proven, producing structure hosting nearly 5.6 million ounces of gold between two major neighbouring projects. TechGen's licences sit directly along this corridor, and none of its priority targets have been drill tested. That asymmetry — established geological context, zero drill data — is precisely what creates exploration upside.
Rather than relying on a single result, TechGen is running geochemistry, ground geophysics, and airborne surveys simultaneously. Each dataset adds interpretive resolution and reduces the risk of drilling the wrong target.
The methodical approach — and the fact that the MLEM survey commenced this week — suggests the company is moving with genuine purpose.
Quartz vein samples returning 6.07 g/t and 3.21 g/t Au at the Armstrong Prospect, combined with arsenic-gold breccia results pointing to a potential deep-seated system, provide tangible surface-level validation for the drilling programme ahead.
TechGen Metals is a diversified WA-focused explorer with projects spanning copper, gold, and antimony across Western Australia, the Northern Territory, and New South Wales. At Dalgaranga, the company has identified a genuinely compelling exploration proposition: multiple undrilled targets sitting along the same major structure responsible for nearly 5.6 million ounces of gold in adjacent projects — with active geophysics programmes underway and a drill programme taking shape.
The combination of a rediscovered 2.5km soil anomaly with no prior follow-up, a new high-grade arsenic-gold breccia target interpreted as the surface expression of a deep gold system, and high-grade quartz vein results at the historic Armstrong workings gives investors three distinct entry points into the exploration story — all ahead of the drill bit.
Consequently, the TechGen Metals Dalgaranga Gold Project new gold targets in Western Australia represent a credible, systematically de-risked opportunity for investors monitoring early-stage exploration plays in proven gold country.
Key Takeaway:
TechGen Metals has positioned itself as a credible early-stage explorer in one of Western Australia's most proven gold corridors, with multiple undrilled targets on the Karbah Shear Zone — the same structure hosting nearly 5.6 million ounces of gold in adjacent projects.
