Yandal Resources has reported significant new reverse circulation drilling results at its Arrakis Prospect, extending the gold mineralisation by 400 metres and confirming continuity over a 2.2km strike. Follow-up diamond drilling and heritage surveys are set to further define this promising discovery in Western Australia.
- New RC drilling extends Arrakis gold mineralisation by 400m
- Significant intercepts include 50m at 1.3g/t Au from fresh rock
- Mineralisation shows consistent sub-vertical geometry over 2.2km strike
- Upcoming 1,200m diamond drilling and infill RC drilling planned
- Heritage surveys scheduled to enable expanded drilling programs
Extending a Promising Gold System
Yandal Resources Ltd (ASX, YRL) has announced encouraging results from its recent reverse circulation (RC) drilling campaign at the Arrakis Prospect, part of the Caladan target area within the Ironstone Well-Barwidgee Gold Project in Western Australia. The new drilling has extended the known gold mineralisation by approximately 400 metres northwest, reinforcing the prospect’s potential as a significant gold discovery.
The standout intercept from hole 25IWBRC0042 includes 50 metres grading 1.3 grams per tonne (g/t) gold starting from 122 metres downhole, with a higher-grade zone of 28 metres at 1.9 g/t gold. Nearby hole 25IWBRC0043 also returned 16 metres at 0.7 g/t gold, including 9 metres at 1.0 g/t. These results are consistent with previous drilling 400 metres to the southeast, which reported 54 metres at 1.2 g/t gold, confirming a continuous mineralised system.
Geological Continuity and Mineralisation Style
The mineralisation at Arrakis is hosted within fresh rock exhibiting a sub-vertical geometry, striking northwest. The style of alteration and deformation fabrics observed in the new drill holes closely matches earlier intercepts, suggesting the mineralisation is part of the same extensive system. This continuity over a 2.2-kilometre strike length is particularly significant given the initial air-core drilling used wider 400m to 800m line spacing, indicating a potentially large-scale gold system.
Alteration minerals such as silica-carbonate, sericite, chlorite, albite, and biotite accompany quartz veining and disseminated sulphides including pyrite and arsenopyrite. These geological features are typical of orogenic gold deposits, which are highly sought after in the Yandal Greenstone Belt, a prolific gold province.
Next Steps, Diamond Drilling and Heritage Surveys
Yandal Resources is preparing for a 1,200-metre diamond drilling program scheduled to commence in October. This program will extend several RC holes with diamond tails and test deeper fresh rock mineralisation below recent intercepts. Additionally, infill RC drilling on 200-metre spaced lines will help refine the understanding of the mineralised system.
To facilitate expanded drilling, a heritage survey clearing 100-metre spaced lines across the Arrakis Prospect is planned for early October, following an earlier survey that cleared 200-metre spaced lines. These surveys are critical to ensure compliance with native title requirements and enable access for further exploration.
Strategic Positioning in a Prolific Gold Belt
The Arrakis Prospect lies within the broader Ironstone Well-Barwidgee Gold Project, approximately 60 kilometres south of the established Jundee mining complex and 18 kilometres north of the recent Siona discovery. This strategic location within the Yandal Greenstone Belt enhances the prospect’s appeal, given the region’s history of significant gold production.
Yandal Resources maintains a robust cash position and an active exploration schedule through the remainder of 2025, including ongoing assay results from additional RC holes and air-core drilling across other targets such as the New England Granite area. The company also anticipates completing the Gordons Gold Project tenement sale agreement shortly, which will provide additional capital and strategic assets.
Bottom Line?
With mineralisation continuity confirmed and follow-up drilling imminent, Yandal Resources is poised to unlock further value from the Arrakis Prospect in the coming months.
Questions in the middle?
- Will the upcoming diamond drilling confirm the true width and depth extent of the mineralisation?
- How will the pending assay results from the remaining RC holes impact the overall resource potential?
- What are the implications of the Gordons Gold Project tenement sale for Yandal’s exploration funding and strategy?
