Highlights
- Yandal expands gold structure to over a kilometre at Caladan
- More drilling and heritage surveys scheduled for further exploration
- Multiple untested structures indicate broader mineralisation trends
Yandal Resources Ltd (ASX:YRL) has revealed a major update from its Caladan target, part of the Ironstone Well-Barwidgee Gold Project in Western Australia. Recent assay results have confirmed an extended gold structure known as Arrakis, now traced for over a kilometre. These findings stem from an air-core drilling program conducted earlier this year. Notably, the structure remains open to both the northwest and southeast, with several additional drill results still pending.
While not listed among ASX 200 stock, Yandal's exploration activities continue to draw attention for their geological significance. The company's focus on systematic drilling and data interpretation has placed the Caladan target among its top exploration priorities.
Strategic Focus on Caladan and New England Granite Targets
Early data from Caladan suggest a substantial folded structure intersected by a major shear zone. This zone, known as the Idaho Shear, connects key geological fault systems and has helped shape the location and form of mineralisation. Initial exploration efforts defined a long regolith anomaly, now termed the Arrakis Prospect, which is currently the primary focus for ongoing work.
Upcoming activities include reverse circulation and further air-core drilling across the mineralised corridor. Heritage surveys are scheduled to ensure safe and compliant access to priority drilling zones. The company has already completed drilling lines beyond the recently extended strike, pointing to possible further discoveries.
Geological Indicators Support Further Work
Previous campaigns have outlined several geological signatures of note. These include gold depletion zones in the regolith, altered mafic units, and strong gravity highs suggesting complex subsurface structures. Drilling in early 2025 supported the presence of vertical shear zones hosting gold-bearing structures in basalt and dolerite. A number of these structures remain untested and are slated for upcoming work.
Additionally, the broader fold structure at Caladan stretches for several kilometres in both width and length, drawing comparisons to mineralised zones in Western Australia's well-known gold districts. The consistency and scale of geological indicators provide strong rationale for ranking Caladan as a leading site within the broader exploration portfolio.
Forward Exploration Path
Looking ahead, Yandal is awaiting lab results from numerous completed drill holes. These findings will inform the next phase of work, which includes targeted drilling across both Caladan and the New England Granite area. This strategic approach underscores the company's focus on methodical, data-driven exploration planning.
Frequently Asked Questions
- What is the significance of the Arrakis structure extension?
The extended strike length indicates a broader gold-bearing corridor, suggesting more exploration potential across Caladan. - Are more drill programs planned at Caladan?
Yes, both reverse circulation and air-core programs are scheduled, along with heritage surveys to facilitate future access. - Why is the Caladan target important in Yandal's portfolio?
Its large-scale fold structure, combined with consistent mineralisation signals, places Caladan at the forefront of Yandal’s exploration focus.
