Gateway Mining’s latest aircore drilling at the Yandal Gold Project reveals significant high-grade gold mineralisation near the bottom of holes along key shear structures, expanding the known gold system.
- High-grade gold intercepts at Celia Shear near bottom of holes
- Widespread gold anomalism over 2.5km strike on Mustang Shear
- Targeted mafic-intermediate contact zones confirmed as mineralised
- Two aircore rigs to intensify drilling with follow-up RC planned
- Strong financial position with $35.6m available for 2026 exploration
Expanding the Yandal Gold System
Gateway Mining Limited (ASX, GML) has reported encouraging results from its ongoing aircore drilling program at the Yandal Gold Project in Western Australia. The company’s exploration efforts are focused on two major shear structures, the Celia Shear and the Mustang Shear, both of which are showing promising signs of significant gold mineralisation.
Recent assays reveal high-grade gold intercepts near the bottom of holes (BOH) on the Celia Shear, with standout results including 2 metres at 3.4 grams per tonne (g/t) gold and 4 metres at 2.9 g/t gold. These intercepts were obtained where the drilling ‘clipped’ the targeted mafic-intermediate contact zone, a geological feature known to host gold mineralisation in the region.
Mustang Shear, A Growing Gold Anomaly
To the east, the Mustang Shear has demonstrated widespread gold anomalism over a strike length of approximately 2.5 kilometres, although the targeted shear zone itself has yet to be precisely intersected. Drilling results show gold grades of 0.3 to 0.4 g/t in saprolite near the expected shear contact, indicating the presence of an extensive mineralised system. Gateway plans tighter spaced aircore drilling to accurately locate this key structure ahead of follow-up reverse circulation (RC) drilling.
Strategic Drilling and Geological Insights
The company is deploying two aircore rigs to accelerate exploration. One rig will conduct infill drilling to close gaps between existing lines and refine the position of the mafic-intermediate contact, while the other will systematically drill southwards along the Mustang Shear to map the mineralised horizon. This approach aims to delineate dilation zones and stronger gold anomalism that could underpin future resource development.
Importantly, geological mapping using titanium to zirconium ratios from bottom-of-hole samples has confirmed a clear stratigraphic link between the Celia and Mustang shears and the nearby Horse Well Gold Camp, a known high-grade gold deposit. This connection underscores the potential scale and continuity of the broader gold system within Gateway’s tenure.
Financial Strength Supports Aggressive Exploration
Gateway Mining remains well funded to execute its 2026 exploration plans, 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 financial position provides the company with the flexibility to expand drilling programs and advance the Yandal Gold Project efficiently.
While some assay results from southern extensions of the Celia Shear and Mustang Shear remain pending, the current data affirms the presence of significant gold mineralisation along key structural corridors. The company is also processing a backlog of diamond core samples, which will provide further insights into the mineralisation style and grade continuity.
Bottom Line?
Gateway’s methodical drilling and strong financial footing set the stage for a potentially transformative year at Yandal.
Questions in the middle?
- Will upcoming infill drilling on the Mustang Shear confirm high-grade gold zones similar to Celia?
- How will the pending assays from southern extensions impact the overall resource potential?
- What are the timelines and targets for the follow-up RC drilling program?
