TechGen Reports 41% Copper Assays and Sets Drilling at El Donna Gold Project

Exploration Momentum Builds in Kimberley

TechGen Metals Limited has delivered a robust quarterly update for the period ending 31 March 2025, highlighting significant progress across its portfolio of Australian gold and base metal projects. The company’s Kimberley projects in Western Australia continue to attract attention following airborne electromagnetic (EM) and magnetics surveys that have delineated compelling high-priority targets at the Blue Devil and Copper Springs sites.

At Blue Devil, three strong bedrock EM conductors were identified, spatially associated with a localized magnetic feature interpreted as a probable intrusion. Rock chip sampling in this area returned exceptional copper grades, with assays hitting 41%, 34.4%, and 30.6% copper. These results underscore the potential for intrusion-related gold, iron oxide copper gold (IOCG), or skarn/porphyry styles of mineralisation, warranting further ground exploration.

Copper Springs also yielded promising geophysical results, with sixteen significant EM targets identified, some coinciding with magnetic highs. These anomalies may represent magmatic or volcanogenic massive sulphide (VMS) deposits akin to the nearby Savannah Ni-Cu Mine, positioning Copper Springs as a key focus for upcoming ground follow-up work.

Gold Targets and Drilling Programs in the Goldfields

TechGen is advancing its gold exploration efforts at the Agnew, El Donna, and Mt Boggola projects. A 600-sample soil geochemistry program is scheduled to commence at Agnew, targeting under-explored areas with limited prior work. Meanwhile, the El Donna project is poised for a two-phase drilling campaign starting next quarter, combining aircore and reverse circulation (RC) drilling to test soil gold and arsenic anomalies as well as historic drill intercepts that remain open at depth and along strike. Notably, previous drill holes at El Donna have returned high-grade gold intersections such as 2m at 17 g/t Au and 2m at 8.23 g/t Au, which have yet to be followed up.

At Mt Boggola, an induced polarisation (IP) geophysical survey is planned to investigate the Northern Star Soil Anomaly, where rock chip samples have yielded remarkable multi-element grades including 48.8 g/t gold, 27.8% copper, and significant antimony and lead values. This survey aims to refine drill targets in a region with strong evidence of intrusion-related mineralisation.

Joint Ventures and Strategic Partnerships

TechGen’s joint venture with Novo Resources at the John Bull Gold Project in New South Wales is progressing with soil sampling and geological mapping completed, and drilling plans underway. Novo’s early-stage work has identified a broad gold and arsenic soil anomaly, with encouraging drill intercepts including 68m at 1 g/t Au from surface.

Similarly, the IGO Limited joint venture at the North Nifty Copper Project in Western Australia is advancing exploration planning for the upcoming field season. The North Nifty project is prospective for sediment-hosted base metal mineralisation, and IGO’s involvement brings significant technical expertise and funding.

Financial Position and Forward Outlook

TechGen remains well-capitalised with a cash balance of $1.369 million as at 31 March 2025 and no borrowings, supporting ongoing exploration activities. The company spent approximately $126,903 on project and exploration activities during the quarter, focusing on advancing key targets and preparing for upcoming drilling and geophysical surveys.

Looking ahead, TechGen plans to commence soil sampling at Agnew, release satellite alteration study results at Blue Devil, conduct the IP survey at Mt Boggola, and initiate the aircore and RC drilling programs at El Donna. Exploration activities at joint venture projects John Bull and North Nifty will continue under partner management, maintaining momentum across the portfolio.

Managing Director Ashley Hood expressed optimism about the drilling campaign at El Donna, highlighting the strategic targeting of soil anomalies along significant fault structures analogous to nearby gold mines. The company anticipates further announcements as assay results and exploration data emerge.
