Yandal Confirms New Gold Discovery at Arrakis with 54m @ 1.2g/t to End-of-Hole

22 September 2025 | West Perth, WA – Yandal Resources (ASX:YRL) has confirmed a new primary gold discovery at the Arrakis prospect within the Caladan target area, reporting 54m @ 1.2g/t Au from 108m to end-of-hole in RC hole 25IWBRC0040, including 24m @ 2.1g/t Au from 138m to EOH and 8m @ 4.7g/t Au from 154m to EOH. A second hole, 25IWBRC0041, returned 6m @ 1.1g/t Au from 180m to EOH. The results are the first from a seven-hole, 1,374m RC program testing beneath broad aircore anomalism along a >2.2km mineralised trend.

Yandal says the RC program confirms fresh-rock mineralisation with an apparent sub-vertical geometry, demonstrating down-dip continuity below earlier aircore intercepts and suggesting gold depletion in the weathered profile relative to broader zones now seen in fresh rock. The company interprets Arrakis as a large-scale mineralised system that remains open along strike and at depth.

Managing Director Chris Oorschot said the fresh-rock hits represent “a significant milestone in de-risking and progressing exploration targets,” adding that “the discovery potential is substantial when you consider the scale of the trend and the limited and broadly spaced nature of current drilling.”

Next steps: Results from the remaining five RC holes are expected in the coming weeks. Yandal is planning to re-enter and extend 25IWBRC0041 with diamond drilling, and to step-out with RC on 200m-spaced lines to test the Arrakis trend to the north-west and south-east. Heritage surveys completed and scheduled through September will open up additional drill positions across Caladan.

Arrakis lies within Yandal’s Ironstone Well–Barwidgee Project, about 60km south of Jundee and 18km north of the Siona discovery, in the Yandal Greenstone Belt.
