Gateway Mining Sharpens Yandal Gold Targets Ahead of Drilling

Context and Survey Overview

Gateway Mining Limited (ASX – GML) has delivered encouraging results from its recent Induced Polarisation (IP) geophysical surveys across its Yandal Gold Project in Western Australia. The surveys, conducted over the Mustang-Pony and Dusk ‘til Dawn areas, have delineated significant chargeability anomalies that align with key geological structures and historic gold intercepts. These findings provide a sharper focus for the company’s upcoming diamond drilling program, which is set to commence imminently.

Mustang-Pony – Untested Structural Targets

At the Mustang-Pony trend, the IP survey identified a 1-kilometre-wide chargeability anomaly adjacent to the large Haflinger intrusive body. This zone exhibits a complex interplay of shear zones, cross-cutting faults, and dilation zones, features that are often conducive to gold mineralisation. Historic rotary airblast drilling in the vicinity intercepted gold grades such as 16 metres at 1.0 grams per tonne and 20 metres at 0.6 grams per tonne, but these holes ended in weathered material and did not penetrate the main shear structures or the newly identified anomaly. This leaves a substantial, untested target area ripe for exploration.

Dusk ‘til Dawn – Structural Complexity and Sulphide Zones

The Dusk ‘til Dawn area, comprising eastern and western intrusive units, revealed very high chargeability responses over a 4-kilometre strike length. These anomalies coincide with shear zone flexures and intersections of northeast-trending faults, as well as elevated gold-copper-molybdenum geochemical signatures. Notably, resistivity anomalies wrapping around sanukitoid intrusive margins suggest alteration zones typical of significant gold deposits. The first diamond drill hole will target the Comanche prospect at the northern end of the Dusk ‘til Dawn intrusive unit, focusing on a 300-metre-wide sulphide-indicative chargeability anomaly adjacent to a fault intersection.

Strategic Implications and Funding

Gateway’s Executive Chairman, Andrew Bray, emphasised the importance of the IP survey in refining drill targets and enhancing the understanding of the project’s structural framework. The company is well positioned financially, with approximately $12.1 million in cash and liquid ASX-listed securities following a recent $22.5 million capital raising. This strong capital base supports the planned 4,600-metre diamond drilling program and ongoing exploration activities through 2025 and 2026.

Looking Ahead

The upcoming diamond drilling campaign will be critical in testing the newly defined IP anomalies and historic gold mineralisation zones, potentially unlocking significant resource expansions. While the IP results provide compelling geophysical evidence, confirmation through drilling and assay results will be essential to validate the scale and grade of mineralisation. Investors and analysts will be watching closely as Gateway advances its exploration program in one of Western Australia’s prolific gold regions.
