Gateway’s Haflinger Discovery Opens New Chapter but Key Questions Remain

A New Chapter in Yandal Gold Exploration

Gateway Mining Limited (ASX, GML) has revealed a compelling new gold discovery at its Haflinger prospect, part of the broader Yandal Gold Project in Western Australia. Recent aircore drilling has intersected a substantial 52 metres grading 1.4 grams per tonne (g/t) gold, including a richer 12-metre interval at 3.1g/t. This result not only confirms the presence of significant mineralisation but also extends a mineralised trend over a strike length of approximately 500 metres.

These findings build on earlier results from the same structural corridor, where bottom-of-hole samples returned high-grade gold intercepts, reinforcing the potential of the Celia Shear Zone as a key host for gold mineralisation. The mineralisation is situated along a structurally complex contact between mafic and intermediate rock types, where geological flexures create favourable conditions for gold deposition through enhanced fluid flow and trapping mechanisms.

Drilling Strategy and Geological Insights

Gateway’s use of aircore drilling has proven effective in penetrating fresh rock beneath transported cover and weathered zones, overcoming limitations of previous rotary airblast drilling. The company’s approach has delineated primary mineralisation within the mafic-intermediate contact over a significant strike length, with consistent grades around 3.0g/t gold in key intercepts spaced hundreds of metres apart.

Looking ahead, Gateway plans to intensify drilling efforts with two rigs on site. One rig will focus on infill drilling to increase the density of samples along the Haflinger trend, aiming to better define the key shear zone. The second rig will systematically advance exploration southwards along the Mustang Shear, targeting the structural flexure where geological complexity and brittle structures intersect, potentially enhancing mineralisation.

Financial Position and Exploration Outlook

Gateway Mining remains well funded to execute its 2026 exploration program, holding approximately $13.1 million in cash and liquid ASX securities at the end of the September quarter, supplemented by a $22.5 million capital raising completed thereafter. This strong financial position supports the company’s aggressive drilling plans and follow-up resource definition work, including planned reverse circulation (RC) drilling to test targets identified by aircore results.

While the current results are promising, the true width of mineralisation and the full extent of the deposit remain to be confirmed. Assay results from recently completed holes are pending and will provide further clarity on the mineralised system. The evolving geological model, combined with systematic drilling, positions Haflinger as a potentially significant new high-grade gold discovery within the prolific Yandal region.
