Highlights

Diamond drilling has commenced in the Thylacine south zone, with a program of approximately 1,200 metres directed at the Numbat lode and surrounding Numbat shear.

The drilling follows a Numbat lode intersection of nine metres at 12.3 grams per tonne gold from 70 metres in hole 26LSRC077.

Three holes totalling approximately 1,000 metres are part of the Western Australian Government’s Exploration Incentive Scheme co-funded program.

Leinster South extends across more than 430 square kilometres, between approximately 10 and 40 kilometres south of Leinster.

Gold explorer Metal Hawk Limited (ASX:MHK) is moving into diamond drilling at its wholly owned Leinster South project in Western Australia. Earlier reverse-circulation drilling at the Numbat prospect returned high-grade gold intercepts, while the latest program is designed to establish more information about the shape and orientation of the mineralised structure. Additional reverse-circulation assays are also pending.

A 1,200-Metre Campaign Begins

Diamond drilling has commenced in the Thylacine south zone, with a program of approximately 1,200 metres directed at the Numbat lode and surrounding Numbat shear. The project lies in the Agnew-Lawlers region of Western Australia. Oriented diamond core will help determine the geometry, plunge and true width of the high-grade zones, information that cannot be fully established from individual downhole intercepts alone.

Previous High-Grade Intercepts Set the Target

The drilling follows a Numbat lode intersection of nine metres at 12.3 grams per tonne gold from 70 metres in hole 26LSRC077. Another hole, 26LSRC075, returned four metres at 12.5 grams per tonne from 43 metres in shear-hosted mineralisation. These assays form the basis of the new program, but reported downhole widths are not the same as true mineralised widths. The orientation of the structure is a key unanswered question.

Government Co-Funding Supports Three Holes

Three holes totalling approximately 1,000 metres are part of the Western Australian Government’s Exploration Incentive Scheme co-funded program. The scheme can contribute up to AUD 175,000 toward direct drilling costs. Metal Hawk is also awaiting laboratory results from 10 recently completed reverse-circulation holes covering 1,642 metres. Those assays were expected around mid-November 2026 and will add information alongside the diamond core program.

Results Will Direct the Next Campaign

Leinster South extends across more than 430 square kilometres, between approximately 10 and 40 kilometres south of Leinster. Exploration has identified several prospects, including Siberian Tiger, Thylacine and Tysons. The immediate focus is the Numbat structure and pending assays, with future drill design depending on the resulting geological interpretation. The announcement does not establish a mineral resource or confirm the commercial viability of the reported gold intercepts.
