Highlights

  • Multiple high-chargeability IP and EM targets defined across Mt Boggola and Blue Devil.
  • High-grade surface rock chip samples return values up to 52.3% Cu and 48.8g/t Au.
  • Drilling approvals and heritage surveys scheduled through late 2025 to early 2026.

TechGen Metals Ltd (ASX:TG1) has outlined significant exploration progress across its Mt Boggola and Blue Devil copper-gold projects in Western Australia, with several induced polarisation (IP) and electromagnetic (EM) targets identified for upcoming drilling. The company’s current portfolio includes multiple Cu-Au-Ag-Sb prospects located in highly mineralised regions such as the Ashburton and Kimberley areas.

At the Mt Boggola Project, four IP chargeability targets (MB1–MB4) have been defined in areas coinciding with strong surface mineralisation. The targets are situated within the Northern Star Cu/Au/Sb/Fe/Pb/As soil anomaly zone, where rock chip samples recorded peak values of 48.8g/t Au, 43.1% Cu, 3.92% Sb, 3.72% Pb, and 49.3% Fe.

Mt Boggola: Four High-Chargeability Targets Defined

Target MB1 has been identified as the strongest anomaly, with chargeability levels exceeding three times background levels and surface copper samples peaking at 10.5%. MB2 displays chargeability above 28mV/V, with rock chip assays up to 39.9% Cu and 48.8g/t Au. Targets MB3 and MB4 show comparable responses, each associated with resistivity anomalies and visible copper gossans.

Newcrest Mining previously drilled near MB1 and MB2 in 1991; however, those holes did not intersect the newly identified IP zones. Drilling at Mt Boggola is planned to commence between late 2025 and early 2026 following completion of heritage surveys and Programme of Work (POW) approvals.

Blue Devil and Red Devil: Large EM Conductors and Surface Mineralisation

At the Blue Devil Project in the Kimberley region, three large late-time EM conductors have been discovered beneath magnetic intrusions, extending approximately 2.75km in length at 200m depth. The project also hosts a high-chargeability IP target at the Red Devil Prospect, where surface sampling returned up to 52.3% Cu, 18.5g/t Au, and 53g/t Ag.

The targets lie within the Halls Creek Orogen, 40km northeast of Halls Creek and 60km from the Great Northern Highway. None of the newly identified anomalies have been drill tested to date, and drilling is expected to begin in Q2 2026 following licence grant and approvals.

Broader Exploration Portfolio and Upcoming Catalysts

TechGen also holds the John Bull Gold Project in New South Wales and the Dalgaranga Gold Project in Western Australia. At Dalgaranga, exploration licences cover 231km² adjacent to Ramelius Resources’ 2.97Moz gold deposit. The Blue Bore Copper Project in the Northern Territory remains prospective for sediment-hosted mineralisation.

Short-term milestones include POW and heritage survey results at Mt Boggola and Blue Devil, along with drilling activities at John Bull and soil surveys at Dalgaranga through Q4 2025 and Q1 2026.
