Metal Hawk has reported strong assay results from recent RC drilling at its Leinster South Project, revealing shallow high-grade gold zones at Thylacine south and east with follow-up drilling planned.
- High-grade gold assays up to 14.1g/t Au from shallow depths
- New mineralised zones confirmed at Thylacine east
- Pending assays for five additional drill holes
- Follow-up drilling scheduled to start in June 2026
- Tysons prospect shows lower grade but remains exploration priority
Shallow High-Grade Gold Intercepts at Thylacine South
Metal Hawk Limited (ASX:MHK) has unveiled compelling assay results from its recent reverse circulation (RC) drilling campaign at the Leinster South Project in Western Australia’s Agnew-Lawlers region. The standout intercepts come from the Thylacine south zone, where three holes drilled beneath a previously identified high-grade quartz vein have returned grades up to 14.1 grams per tonne (g/t) gold from as shallow as 32 metres.
Notably, hole 26LSRC066 delivered 3 metres at 9.82g/t Au including 2 metres at 14.1g/t Au from 32 metres, while 26LSRC065 returned 6 metres at 2.83g/t Au including 3 metres at 4.2g/t Au from the same depth. These results confirm the continuity of the high-grade quartz vein intersected in late 2025 diamond drilling, though the vein’s dip appears shallower than initially modelled. The steep plunge of the mineralised shoot remains open at depth, inviting further targeted drilling to delineate its extent.
These latest results build on the company’s prior diamond drilling success, which included a 2.3 metre intercept grading 15.3g/t Au reported in December 2025. The current RC program’s ability to confirm and extend these zones highlights the potential scale of the mineralised system at Thylacine south and underscores the project’s growing significance within Metal Hawk’s portfolio. This progress follows the company’s earlier maiden diamond drilling program that first outlined high-grade gold mineralisation at Leinster South.
New Gold Zones Emerging at Thylacine East
Beyond the southern zone, four new RC holes at Thylacine east have revealed additional mineralised quartz veining. Hole 26LSRC068 intersected two significant intervals: 8 metres at 3.2g/t Au from 26 metres and another 8 metres at 3.0g/t Au from 148 metres. These broad zones of mineralisation, previously untested at shallow depths, suggest a more extensive gold system than previously recognised.
Metal Hawk is conducting 1-metre resampling on the deeper composite intervals to better define grade continuity and plans further drilling to clarify the orientation and lateral extent of these veins. Pending assay results from holes 26LSRC069 to 26LSRC073, expected within weeks, will be critical to refining the geological model and drill targeting strategy.
Tysons Prospect Shows Lower Grade but Remains a Focus
The Tysons prospect, located along a structurally significant granite-greenstone contact, delivered modest gold mineralisation with a composite interval of 12 metres at 0.42g/t Au including 4 metres at 0.83g/t Au from 40 metres. While the recent Sub-Audio Magnetics (SAM) geophysical target north of Tysons did not yield immediate follow-up results, the structural corridor remains a high-priority exploration target for Metal Hawk.
Earlier this month, Metal Hawk secured $175,000 in government co-funding to advance diamond drilling at Tysons, focusing on this contact zone that could host additional gold mineralisation. This funding boost complements ongoing exploration efforts and reflects the company’s commitment to unlocking value across Leinster South’s multiple prospects, including the promising Thylacine and Tysons areas. The recent $175,000 government co-funding provides a timely injection to support these initiatives.
Next Steps and Exploration Outlook
Metal Hawk plans to recommence RC drilling at Leinster South in June 2026, with follow-up programs designed to test the depth extensions and strike continuity of the high-grade shoots at Thylacine south and east. The company is also preparing for more detailed 1-metre sampling to resolve grade variability within broader composite intervals.
With assay results pending for five recent holes, the upcoming data release will be closely watched for confirmation of the mineralised system’s scale and geometry. The orientation and true widths of the gold zones remain to be fully understood, leaving open questions about the potential resource size and mining viability.
Bottom Line?
Metal Hawk’s shallow high-grade gold hits at Leinster South reinforce exploration momentum, but pending assays and structural uncertainties mean the story is far from complete.
Questions in the middle?
- Will pending assays confirm the continuity of high-grade veins at depth?
- How will the structural interpretation of the quartz veins evolve with new data?
- Can the Tysons granite-greenstone contact yield economically viable gold mineralisation?
