Coarse Gold Variability Clouds Yidby Resource Outlook Despite Strong Drilling

Emerging Gold System in Western Australia

Surefire Resources NL (ASX, SRN) has released promising assay results from its recent reverse circulation drilling campaign at the 100% owned Yidby Gold Project, located in the Mid-West region of Western Australia. Situated approximately 320km northeast of Perth, Yidby is an emerging large gold system surrounded by several multimillion-ounce deposits, underscoring its regional significance.

The latest drilling has revealed thick mineralised zones with gold grades reaching up to 4.57 grams per tonne over widths as wide as 100 metres. These results span multiple prospects within the project area, including Yidby, Marshall, and Fender, confirming the extensive nature of the gold system and its potential for repeated mineralised zones.

Addressing Coarse Gold Variability

One of the notable challenges highlighted by Surefire is the presence of coarse, “nuggety” gold, which has led to variability in assay results from initial 4-metre composite samples. To better define the true gold content, the company is now submitting detailed 1-metre interval samples for assay using advanced techniques such as Photon assay, Screen fire assay, or Leachable Bottle Roll. This approach aims to overcome the underreporting risk associated with coarse gold and provide a more accurate grade assessment.

Such variability is not uncommon in Yilgarn gold systems, and Surefire’s proactive response demonstrates a commitment to robust resource evaluation. Early data comparisons indicate that single metre assays can show significant grade increases compared to composite samples, reinforcing the importance of this detailed analysis.

Advancing Towards Resource Estimation and Mining Licence

With sufficient drilling completed, Surefire has appointed a resource consulting geologist to commence a maiden JORC Mineral Resource Estimate. Concurrently, preparations are underway to submit a Mining Licence application, marking a critical step towards potential development and production.

The drilling results also confirm that mineralisation remains open both at depth and along strike, suggesting considerable upside potential. Notably, the “Money anomaly” prospect remains untested due to access issues, representing an additional exploration target.

Expanding Exploration Focus

Beyond the core Yidby area, Surefire is turning attention to other prospects within its tenure, including Cashen’s Find and Delaney Well. These historic workings have shown encouraging high-grade gold intersections in previous drilling, and the enhanced geological understanding gained from the Yidby program has elevated their prospectivity. Incorporating these targets into the exploration pipeline could further enhance the project’s value proposition.

Overall, Surefire’s methodical approach, combining extensive drilling, detailed sampling, and strategic resource development, positions the Yidby Gold Project as a compelling asset in the Western Australian gold landscape.
