17.7m at 1.4g/t Au Confirms Depth Extension at Yandal’s Arrakis Prospect

Diamond Drilling Validates Depth Potential

Yandal Resources Limited (ASX – YRL) has delivered a significant exploration update from its Arrakis Prospect within the Ironstone Well-Barwidgee Gold Project in Western Australia. The company’s first full diamond drill hole from surface, 25IWBDD0011, intersected a notable 17.7 metres grading 1.4 grams per tonne gold starting at 309.3 metres depth, including a higher-grade segment of 7.95 metres at 2.5 grams per tonne. This intercept lies approximately 120 metres beneath previously reported high-grade reverse circulation (RC) drilling results, underscoring the prospect’s vertical continuity and potential for deeper mineralisation.

Expanding the Mineralised Footprint

The Arrakis mineralised system extends over a 2.2-kilometre strike length, with the trend remaining open to the southeast. Earlier RC drilling along this strike has returned broad zones of gold mineralisation, including a standout 56.5 metres at 1.3 grams per tonne from 108 metres depth. The diamond drilling results corroborate the geological model developed by Yandal’s exploration team, confirming that mineralisation can be visually identified within fresh rock and that higher-grade zones are present both along strike and at depth.

Accelerating Exploration with Additional Resources

To expedite the ongoing drilling program, Yandal has mobilised a second RC rig to the Arrakis site, aiming to complete approximately 5,000 metres of drilling on 200-metre spaced lines. This intensified effort is designed to delineate the extent and variability of mineralisation across the strike and at depth. Complementing this operational scale-up, the company has secured a 21-person transportable camp, scheduled for installation in early 2026, which will support an expanded field team and enable multi-rig drilling campaigns.

Strategic Implications and Next Steps

Yandal’s Managing Director, Chris Oorschot, highlighted the significance of these results, noting that the diamond drilling validates the geological model and confirms the presence of both broad and higher-grade mineralisation styles. The company anticipates a steady flow of assay results from the current diamond and RC drilling programs through December and January, which will further clarify the scale and grade distribution of the Arrakis system. Additionally, air-core drilling results from adjacent target areas are expected soon, potentially expanding the project’s footprint.

Looking ahead, Yandal plans to continue drilling at closer 100-metre line spacing in 2026, alongside further diamond drilling and geophysical surveys. These efforts aim to build a robust understanding of the deposit’s geometry and support future resource estimation. The combination of strong assay results, accelerated drilling, and upgraded infrastructure positions Yandal Resources to advance the Arrakis Prospect toward a potential resource upgrade in the near term.
