Metal Hawk Limited’s recent Sub-Audio Magnetics survey at Leinster South has pinpointed a promising new gold target north of the Tysons prospect, setting the stage for a targeted drilling campaign in February 2026.
- New 400m x 100m conductive zone identified along granite-greenstone contact
- Multiple gold mineralisation styles confirmed by petrographic analysis
- High-grade gold previously intersected south of the new target
- Reverse circulation drilling scheduled to start February 2026
- Additional exploration planned at Thylacine and Pepperill Hill
Exploration Breakthrough at Leinster South
Metal Hawk Limited (ASX, MHK) has revealed a significant new gold exploration target at its Leinster South Project in Western Australia’s prolific Agnew-Lawlers region. The discovery follows the completion of a high-resolution Sub-Audio Magnetics (SAM) survey, which identified a substantial zone of strong conductivity measuring approximately 400 metres by 100 metres. This zone lies north of the established Tysons gold prospect and aligns with a major granite-greenstone contact, a geological setting known to host gold mineralisation.
Geophysical Insights and Geological Context
The SAM survey, conducted using UAV-assisted technology in late 2025, was designed to detect concealed structural features indicative of gold mineralisation. The newly identified conductive zone suggests potential shearing or deformation along the granite-greenstone boundary, which is often associated with quartz-vein-hosted and sulphide-related gold deposits. Notably, limited drilling south of this target has already intersected high-grade gold, lending credence to the prospectivity of the area.
Petrographic Analysis Reveals Multiple Mineralisation Styles
Complementing the geophysical data, detailed petrographic studies of rock samples from the Leinster South prospects have confirmed the presence of multiple gold mineralisation styles. These include classic lode gold systems as well as previously untested exhalative-style zinc-copper-gold and epithermal copper-gold mineralisation. Such diversity not only broadens the exploration potential but also opens avenues for new target generation through focused geochemical surveys and follow-up drilling.
Upcoming Drilling and Exploration Plans
Building on these encouraging findings, Metal Hawk is preparing to commence a reverse circulation (RC) drilling program in February 2026. The drilling will primarily focus on testing the newly identified SAM target along the granite-greenstone contact north of Tysons, as well as following up on recent high-grade gold intersections at the Thylacine prospect. Additionally, regional exploration activities, including mapping and geochemical sampling, are set to resume at Leinster South and the nearby Pepperill Hill tenements.
Strategic Implications for Metal Hawk
This exploration update marks a pivotal moment for Metal Hawk as it leverages advanced geophysical techniques and petrographic insights to refine its targeting strategy. The integration of these data sets enhances the company’s confidence in prioritising structurally controlled gold mineralisation zones, potentially accelerating the path toward resource definition. Investors will be watching closely as the upcoming drilling results could materially influence Metal Hawk’s growth trajectory in a highly competitive gold exploration landscape.
Bottom Line?
February’s drilling results will be critical to validating Metal Hawk’s new gold targets and shaping the next phase of exploration.
Questions in the middle?
- Will the upcoming RC drilling confirm economically viable gold mineralisation at the new SAM target?
- How might the discovery of exhalative and epithermal mineralisation styles influence future exploration strategies?
- What are the implications of these findings for Metal Hawk’s resource potential and valuation?
