Yidby Mineralisation Open at Depth: What Risks Lie Ahead for Surefire Resources?
Surefire Resources reports broad, high-grade gold mineralisation at its Yidby Gold Project in Western Australia, with assays revealing up to 15.83 g/t gold over 1m and a mineralised envelope exceeding 100m. The discovery opens new drilling targets for early 2026.
- Broad mineralised envelope of 108m at 0.61 g/t Au including high-grade zones
- Peak intercept of 1m at 15.83 g/t Au in drill hole YBRC136
- Mineralisation open along strike and at depth with north-westerly plunging system
- Next drilling campaign planned for Q1 2026 to expand resource understanding
- Project positioned as potential near-term production opportunity amid strong gold prices
Exploration Breakthrough at Yidby
Surefire Resources NL (ASX, SRN) has announced compelling new assay results from its 100% owned Yidby Gold Project, located in the Mid-West region of Western Australia. The latest reverse circulation drilling has revealed a broad zone of gold mineralisation extending over 108 metres at an average grade of 0.61 grams per tonne (g/t) gold, punctuated by impressive high-grade intervals including a standout 1 metre intercept grading 15.83 g/t Au.
This discovery marks the broadest mineralised envelope identified at Yidby to date, underscoring the project's potential to host a significant gold system. The standout hole, YBRC136, delivered multiple high-grade zones within the broader mineralisation, including 2 metres at 10.72 g/t Au and 6 metres at 4.29 g/t Au, highlighting the zonal nature of the deposit.
Geological Context and Structural Insights
The Yidby Gold Project sits within the Yalgoo-Singleton Greenstone Belt, a prolific geological province known for hosting major gold and base metal deposits. The mineralisation is associated with an orogenic gold system, hosted primarily in quartz veins within ultramafic and basaltic rocks. Structural modelling indicates a north-westerly plunging mineralised system that remains open both along strike and at depth, suggesting significant upside potential for resource expansion.
Notably, higher-grade mineralisation appears to increase at depth, with intercepts such as 2 metres at 12.54 g/t Au from 177 metres depth in YBRC136, indicating the possibility of repeated mineralised shoots along the plunge. This structural understanding is critical for targeting future drilling and refining resource models.
Strategic Positioning and Next Steps
Executive Chairman Vladimir Nikolaenko highlighted the project's strategic advantages, noting its shallow mineralisation and excellent accessibility just 3.5 hours northwest of Perth. With gold prices currently above AUD 6,000 per ounce, Yidby could emerge as a near-term production asset capable of generating significant cash flow.
Surefire plans to commence a follow-up drilling program in the first quarter of 2026 to further delineate the mineralised envelope and test new targets identified by the structural model. These efforts will feed into upcoming feasibility studies aimed at advancing Yidby towards production.
While the results are promising, the company cautions that true widths of mineralisation are yet to be determined and that forward-looking statements carry inherent risks. Nonetheless, the current data provides a strong foundation for continued exploration and development.
Bottom Line?
Surefire’s Yidby discovery sets the stage for a pivotal drilling campaign in 2026 that could redefine its production outlook.
Questions in the middle?
- How will upcoming drilling refine the size and grade continuity of the Yidby deposit?
- What are the timelines and capital requirements for advancing feasibility studies?
- How sensitive is the project’s economics to fluctuating gold prices and potential royalties?
