TechGen Metals Lines Up Five Undrilled Gold Targets for Q4 Drilling at Dalgaranga
Key Takeaways
- TechGen Metals has identified five Priority 1 magnetic gold targets (T1–T4 and T7) at its 100%-owned Dalgaranga Gold Project, none of which have ever been drill tested.
- The project bookends Ramelius Resources' Dalgaranga Gold Project (2.97Moz @ 5.61g/t Au) and sits just 8km from Ramelius's operating processing plant — infrastructure that already exists and processes ore from the same shear zone.
- Rock chip sampling at the Armstrong Prospect returned grades up to 39.3 g/t Au, 25.8 g/t Au, and 12.0 g/t Au from a historic WMC trial pit that has never been drill tested below surface.
- Target T3 shows coincident arsenic-gold geochemistry (up to 7.3% As and 1.235 g/t Au) overlapping a magnetic anomaly — a combination that strengthens the geological case for a first-pass drill test.
- Drilling is targeted to commence before the end of Q4 2026, pending Heritage approvals, using a combination of Aircore and RC methods across the priority target areas.
Five new priority gold targets identified at Dalgaranga
TechGen Metals (ASX: TG1) has identified five new Priority 1 gold targets at its 100%-owned Dalgaranga Gold Project in Western Australia, following interpretation of a detailed airborne magnetic and radiometric survey flown in June 2026. The project bookends Ramelius Resources’ Dalgaranga Gold Project (2.97Moz @ 5.61g/t Au) and sits just 8km from Ramelius’s operating processing plant, placing TechGen’s tenements squarely within a proven gold-producing corridor.
In total, the survey interpretation has identified 9 targets across the project area. Five of those are classified Priority 1 (T1–T4 and T7), and none have previously been drill tested.

Q4 2026 drilling campaign takes shape across undrilled targets
The central investor point here is straightforward: every one of the five newly identified Priority 1 magnetic targets is going into a drill programme without any prior drill testing to draw on. That means the upcoming holes will be genuinely first-pass tests of geophysically defined targets in a corridor that hosts multi-million-ounce gold deposits.
Project snapshot:
- Ownership: 100% TechGen Metals (all three tenements)
- Tenements: E59/3024, E59/3059 & E59/3064
- Location: 475km northeast of Perth, 55km northwest of Mount Magnet, WA
- Distance to infrastructure: 8km from Ramelius’s Dalgaranga processing plant
- Drilling method: Combination of Aircore and RC drilling planned
- Next catalyst: Heritage approvals, with drilling targeted to commence before the end of Q4 2026
All nine targets identified to date sit 100% within TechGen’s tenements and are outside any overlapping proposed reserves or parks.
The full target list from the airborne magnetics survey is set out below:
| Target | Description | Priority |
|---|---|---|
| T1 | Discrete/complex magnetic zone, possible magnetic remanence, structural complexity, just west of Armstrong Au pit area. | 1 |
| T2 | Discrete remanent magnetic unit, structural complexity. Just to the north of Armstrong Au pit. | 1 |
| T3 | Discrete remanent magnetic unit, structural complexity, overlapping and coincident to arsenic & gold geochemical anomalism. | 1 |
| T4 | Zone of structural complexity/dilational zone potentially from a Au perspective, just south of the Western Reefs Au soil anomalism. | 1 |
| T5 | Discrete remanent magnetic unit, structural complexity, just east of the Western Reefs Au soil anomalism. | 2 |
| T6 | Zone of structural complexity/dilational zone potentially from a Au perspective. | 2 |
| T7 | Zone of structural complexity/dilational zone potentially from a Au perspective, partially coincident with VMS & Au in soil target area. | 1 |
| T8 | Discrete magnetic high, multiple faults/fault bound E and W, just east of VMS soil target area/anomalism. | 2 |
| T9 | Discrete magnetic high, multiple faults/fault bound E and W, just east of VMS soil target area/anomalism. | 2 |
What airborne magnetics reveals — and why it matters for gold exploration
An airborne magnetic and radiometric survey is a geophysical tool flown by aircraft that detects subtle variations in the Earth’s magnetic field to map rock structures beneath the surface. Different rock types produce different magnetic signatures, allowing geologists to identify structural features, intrusive bodies, and shear zones without putting a single drill hole in the ground.
Two terms appear repeatedly in the target descriptions above: magnetic remanence and structural complexity. Magnetic remanence refers to rocks that retain a permanent magnetic signature from ancient geological events, which can indicate specific rock types or hydrothermal alteration associated with gold mineralisation. Structural complexity describes zones where faults, folds, or shear movements have created the kind of dilational (opening) spaces where gold-bearing fluids tend to accumulate.
Both features are significant indicators for gold mineralisation in greenstone belts like the Dalgaranga Greenstone Belt. The regional Karbah Shear Zone — a major crustal structure running through the project area — hosts both Ramelius’s Dalgaranga Gold Project (2.97Moz @ 5.61g/t Au) and the Big Bell Gold Mine operated by Westgold Resources (2.6Moz @ 1.7g/t Au). For investors, the practical value of geophysics at this stage is capital efficiency: narrowing drill locations before committing drilling expenditure means each hole targets a defined geological feature rather than open ground.
IP survey results at Mt Boggola showed how TechGen applies sequential geophysical interpretation across its project portfolio, running an IP survey after initial surface sampling to define drill-ready conductors before committing capital to the first holes.
Armstrong Pit, T3 arsenic-gold anomaly, and the Karbah Shear connection
Armstrong Prospect — high-grade surface results at a never-drilled historic working
The Armstrong Pit is a trial pit originally excavated by WMC in 1986, approximately 60m long x 4m wide x up to 5m deep. Historic production from the pit recorded 107 tonnes @ 2.5g/t Au from quartz vein material.
TechGen’s own rock chip sampling of the Armstrong workings returned high-grade gold results including:
- 39.3 g/t Au
- 25.8 g/t Au
- 12.0 g/t Au
- 8.89 g/t Au
- 7.85 g/t Au
- 5.57 g/t Au
Critically, the pit and the broader project have never been drill tested. The T1 and T2 magnetic targets sit immediately west and north of the Armstrong pit respectively, meaning the upcoming drill programme will provide the first subsurface test of what is clearly a mineralised surface expression.
The Armstrong Prospect discovery brought the highest of those rock chip results, the 39.3 g/t Au return, into sharp focus as a surface expression of what may continue at depth along the same quartz vein system that WMC originally excavated in 1986.
T3 target — arsenic-gold geochemistry converges on magnetic anomaly
T3 sits approximately 1.4km northeast of the Armstrong workings. Quartz-iron vein material sampled by TechGen at this location has returned anomalous arsenic and gold results including:
- 7.3% As & 0.458 g/t Au
- 1.94% As & 1.235 g/t Au
- 1.79% As
Arsenic is a well-recognised pathfinder element for gold in orogenic gold systems — it tends to travel with gold-bearing hydrothermal fluids and precipitate in the same structural traps. Elevated arsenic in soil or rock chip samples, coincident with a magnetic anomaly, strengthens the geological case for a drill test at T3.
T4, the fourth Priority 1 target, sits in close proximity to a historic gold-in-soil anomaly identified by Western Reefs Limited in 1997.
Ashley Hood, Managing Director
“Our Dalgaranga tenement package basically bookends Ramelius Resources Dalgaranga Mine site, until very recently the mine has historically produced at around the 1gram per tonne mark, that was until the very recent high-grade lodes discovered (Never-Never, Pepper and Freak lodes). With the historically low-grade production at Dalgaranaa may somewhat explain why the broader region has been grossly under explored, until now. We’re delighted to be able to add an additional five new magnetic targets to the already untested Armstong Pit (WMC 1986), the historic Western Reefs gold in soil anomaly and the Company’s recent gold and arsenic anomaly that straddles the Karbah Shear, all to be drill tested hopefully late in the year depending on Heritage approvals. The Company is expediting the process to the best as it possibly can.”

What comes next for TechGen at Dalgaranga
Heritage Surveys have been booked and the Company is actively expediting the approvals process. In parallel, 3D inversion modelling of the five Priority 1 targets is continuing, which will further refine drill hole positioning before rigs are mobilised.
Drilling is targeted to commence before the end of Q4 2026, using a combination of Aircore and RC drilling across the priority target areas. The timeline remains contingent on Heritage approvals being received.
The broader setup is a 100%-owned project adjoining a 2.97Moz gold deposit, with nine undrilled targets sitting along a regionally significant shear zone, an operating processing plant 8km away, and an imminent drill programme that will deliver the first-ever subsurface test of targets defined by both geophysics and surface geochemistry.
