Highlights
- Surefire Resources begins 5,500-metre RC drilling at Yidby Gold Project
- Focus on expanding mineralisation zones and supporting scoping study
- Target prospects include Yidby, Fender, Marshall, and Money anomaly
Surefire Resources NL (ASX:SRN) has embarked on a significant 5,500-metre reverse circulation (RC) drilling campaign at its 100%-owned Yidby Gold Project in the Murchison region of Western Australia. This drilling program is designed to extend known gold zones, evaluate new high-priority targets, and gather critical data for a future scoping study aimed at project development.
The RC drilling will test mineralisation both along strike and at depth across four key prospects — Yidby, Fender, Marshall, and the Money anomaly. These efforts are aimed at enhancing the understanding of the gold system’s scale and unlocking further potential in one of the most geologically favourable belts in the state.
Target Areas: Expanding Exploration Horizons
- Yidby Prospect: Known for high-grade intercepts like 10 metres at 10.10 g/t gold including 1 metre at 82.5 g/t, the mineralised corridor here stretches over 900 metres and remains open in all directions. Recent structural data and BoxScan analysis suggest the potential for large-scale gold systems.
- Fender Prospect: This area features continuous gold zones linked with subvertical porphyry intrusions, including 20 metres at 0.4 g/t and 32 metres at 0.32 g/t. Drilling will focus on extending mineralisation northward.
- Marshall Prospect: Just 150 metres west of Yidby, it includes broad gold zones such as 60 metres at 1.04 g/t with high-grade segments. The latest campaign aims to test northern continuity.
- Money Anomaly: Spanning 1.5 kilometres, this geochemical anomaly will undergo first-pass drilling. Magnetic and structural data indicate a dilation zone conducive to gold deposition.
Geology and Structural Potential
The Yidby Gold Project lies within a folded greenstone sequence on a granite basement, along the Mt Gibson–Mt Magnet shear zone — a corridor known for housing significant orogenic gold deposits in the Yilgarn region. Mineralisation is predominantly associated with demagnetised fold limbs and shear-adjacent porphyries, offering repeated potential for economic gold intersections.
Supporting Scoping Study and Metallurgical Analysis
The drill campaign will not only expand the resource base but also generate essential data for an upcoming scoping study. Prior metallurgical testing yielded high cyanide leach recoveries (up to 99.5%) and gravity recoveries of 67%. Additional column VAT leach tests and planned Screen Fire Assays aim to refine understanding of coarse gold distribution and boost resource confidence.
Surefire's renewed exploration at Yidby is timely, especially amid sustained high gold prices. The results of this drilling campaign will be pivotal in guiding development decisions for the project and could elevate interest from broader investor circles, particularly those tracking key ASX200 stocks in the gold sector.
With further diamond drilling in the pipeline to support metallurgical modeling, the momentum at Yidby signals growing potential for long-term value creation within the ASX-listed gold exploration landscape.
