Surefire Resources has reported new on-surface float rock gold assays up to 13.19 g/t from its Yidby Loot Prospect in Western Australia, following an amended JORC table submission. The discovery highlights significant gold mineralisation hosted in Albitite rock over a 165m strike length.
- High-grade gold assays up to 13.19 g/t Au from surface float rock
- Gold mineralisation hosted in Albitite lithology over 165m strike
- JORC table amended to include detailed float rock sampling methodology
- Further drilling planned to define mineralisation orientation and extent
- Albitite occurrences linked to major gold deposits in Western Australia
New High-Grade Gold Assays Confirm Loot Prospect Potential
Surefire Resources NL (ASX:SRN) has delivered a strong follow-up to its March discovery at the Yidby Loot Prospect, with recent on-surface float rock samples returning gold grades as high as 13.19 grams per tonne (g/t). These results, collected along a 165-metre strike length, reinforce the significance of gold mineralisation hosted within the Albitite lithology, a previously underexplored rock type at the 100% owned Yidby Gold Project in Western Australia's Mid-West region.
The company amended its JORC table following an ASX request to clarify the float rock sampling methodology, with competent person Edd Prumm overseeing the update. The detailed sampling approach involved collecting multiple float rock samples greater than 100mm in size at each GPS location, focusing on the distinctive Albitite lithology known to carry consistent gold values above 1 g/t.
Albitite: An Emerging Host for Gold Mineralisation
Albitite, a sodic metasomatic rock rich in albite, forms through sodium alteration of precursor igneous or metamorphic rocks. At Yidby, gold mineralisation is contained within fine-grained grey Albitite featuring euhedral sulphide casts, which are visible in samples like LT027 that graded 10.2 g/t Au. This style of mineralisation is associated with hydrothermal fluid pathways in shears and fault systems within a high-grade metamorphic terrane.
Notably, Albitite is linked to several major Western Australian gold deposits, including the New Celebration deposit along the Boulder Lefroy-Golden Mile fault system and the St Ives camp near Kambalda. The Loot Prospect's proximity to the historic Cashens open pit, where Albitite rock was also identified, suggests potential extensions of mineralisation that merit further exploration.
Sampling and Assay Details Support Exploration Confidence
The float rock samples were assayed by Nagrom Laboratories in Perth using a 50-gram fire assay technique, a standard method for precise gold analysis. Assay results from 14 float samples revealed a range of gold grades, with several samples exceeding 7 g/t and a standout 13.19 g/t. These results build on earlier findings reported in March 2026, where surface samples from the Loot Prospect yielded up to 12.04 g/t Au, confirming the consistency of this new mineralised zone.
Surefire's exploration program also includes reverse circulation (RC) drilling designed to test the mineralisation at near-orthogonal angles, helping to define the geometry and continuity of the gold-bearing zones. The company plans to follow up with additional drilling once all assay results are received, aiming to delineate the mineralisation's down-dip and strike extensions more accurately.
This latest announcement comes amid ongoing efforts by Surefire to unlock the potential of the Yidby Gold Project, which has delivered multiple high-grade intercepts in recent quarters. The company's methodical approach to sampling and rigorous QAQC protocols provide a solid foundation for advancing the project toward resource definition.
What Lies Ahead for Yidby and Surefire Resources
While the true widths of the mineralised zones at Loot remain to be determined, the robust surface assay results and geological context underscore the prospectivity of the Albitite-hosted gold system. The amended JORC table enhances transparency and aligns with ASX requirements, reassuring investors of the quality of the data underpinning Surefire's exploration narrative.
As Surefire prepares for its next phase of drilling, the market will be watching how these new assay results translate into a more detailed resource model. The potential to identify a new corridor of high-grade gold mineralisation within the Yidby project area could materially influence the company's valuation and development trajectory in a competitive Western Australian gold exploration landscape.
Bottom Line?
Surefire’s high-grade gold assays at Loot validate Albitite as a promising host, but the true scale awaits confirmation from upcoming drilling.
Questions in the middle?
- How will further drilling refine the geometry and continuity of the Albitite-hosted gold mineralisation?
- Can the Loot Prospect’s mineralisation be economically integrated with nearby historic pits like Cashens Find?
- What exploration techniques will Surefire employ to leverage the density contrast of Albitite for targeting?
