Gateway flags major gold target after 134-nugget haul at Great Western

17 September 2025 | Subiaco, WA – Gateway Mining (ASX:GML) has reported a significant 134-nugget find totalling 366g (~11.8oz) across a 1.2km corridor at its Great Western prospect, strengthening the case for a near-surface gold discovery along an untested splay structure at the Yandal Gold Project.

Key points

• Nuggets recovered along the mafic–intermediate contact, the same lithological contact that hosts high-grade mineralisation at nearby Horse Well; peak nugget 26.5g, many angular and associated with angular quartz, supporting an ‘in situ’ interpretation.
• Nugget trend is coincident with a soil gold anomaly and wraps the Great Western intrusion; the corridor has never been sampled or drilled historically.
• Gateway is well-funded (~$12.1m cash and liquid securities at 30 June) to continue 2025–26 exploration.

Incoming Executive Chairman Andrew Bray said the large nugget haul, combined with mapping and geochemistry, “adds to the evidence for very significant gold mineralisation” at Great Western, noting that the setting suggests mineralisation could be intersected near or at surface.

What’s next

• Expanded soil sampling and mapping along the intrusion margins now underway.
• A trial 2D IP line across the peak gold anomaly (after completing a 3D IP survey at Dusk ’til Dawn).
• Drilling plans to follow once results are received and integrated.
