Highlights
- Exploration at the Yidby Gold Project continues to expand the known extent of mineralisation through drilling and surface sampling.
- Reverse circulation drilling in December 2025 identified a 108-metre mineralised interval with multiple higher-grade zones.
- A new prospect named “Loot” has been identified at Yidby.
- Fieldwork has outlined an approximately 2-kilometre mineralised corridor linking Loot and Cashens Find prospects.
- A 10,000-metre, two-stage drilling program is underway to test extensions, depth continuity, and new geophysical targets.
Surefire Resources NL (ASX:SRN), an ASX-listed mineral exploration company, continues to build momentum at its Yidby Gold Project, a key component of the company’s exploration portfolio in Western Australia. Located within a prospective greenstone belt, the project has been the focus of sustained geological studies, drilling programs, and surface exploration. With multiple mineralised zones identified and new targets emerging, Yidby continues to evolve as a significant area of interest for gold exploration.
Project Setting and Geological Context
Yidby is situated in the Mid-West region of Western Australia within the Yalgoo-Singleton Greenstone Belt. The project comprises multiple granted exploration licences and includes several established prospects where gold mineralisation has been identified.
The project is allocated near several significant gold deposits, and mineralisation covers 80m width, with indications that it remains open in all directions.
Expanding Mineralisation Footprint at Yidby
Exploration at Yidby has continued to extend the known footprint of gold mineralisation through ongoing drilling programs. In December 2025, assay results from reverse circulation drilling highlighted the widest mineralised zone recorded at the project, including a 108-metre intercept with embedded higher-grade intervals. These results indicate that the project’s mineralisation is ‘robust’ with considerable thickness.
Results released in September 2025 also outlined broad mineralised zones and confirmed continuity along significant strike lengths. These outcomes build on previous drilling campaigns that have progressively expanded the mineralised system and contributed to identifying additional structural targets for further exploration across the project area.
New Surface Discovery Extends Exploration Footprint
Recent on-surface rock sampling has led to the identification of a new gold prospect, named “Loot,” within the Yidby deposit. Sampling returned gold grades of 1.70 g/t, 3.66 g/t and up to 12.04 g/t from an unexplored area in distinct felsic albitite lithology.
The discovery was made following exploration work completed in February 2026, targeting areas highlighted by historical records from Western Mining Corporation dating back to the 1970s.
Emerging Two-Kilometre Mineralised Corridor
Fieldwork and validation of historical data have outlined a mineralised corridor extending approximately two kilometres, highly prospective for identification of additional on surface mineralisation.
Within the Loot and the Cashens Find prospects, gold mineralisation is associated with albitite-rich (+90%) rocks, characterised by fine-grained felsic material and sulphide features.
Drilling Programs Target Expansion and Depth Potential
The company is progressing a 2-stage reverse circulation drilling program of approximately 10,000 metres, designed to test extensions of known mineralisation and evaluate new targets. The program includes drilling along strike and at depth within the main Yidby zone, as well as assessing north-south extensions at Cashens and geophysical targets at Copper Hill.
The Yidby Gold Project continues to develop through systematic exploration and ongoing geological assessment. Multiple prospects, expanding mineralised zones, and a combination of exploration techniques contribute to a growing understanding of the project area. As work progresses, further drilling and analysis are expected to define the extent of mineralisation and guide future exploration activities.
