Announcement
Yandal Resources Ltd (ASX: YRL) has confirmed a new gold discovery at the Arrakis Prospect within the Caladan target area of the Ironstone Well–Barwidgee Project — a major milestone that de-risks exploration and advances the project (Figure 1). With 54m @ 1.2g/t Au from fresh rock, including 8m @ 4.7g/t Au, the result highlights scale and continuity over more than 2.2km of strike.

Key Highlights: Gold Discovery
54m @ 1.2 g/t Au from 108m, including 24m @ 2.1 g/t Au and 8m @ 4.7 g/t Au from 154m to EOH (Hole 25IWBRC0040) (Figure 2).

Confirmation of primary mineralisation within fresh rock, demonstrating down-dip continuity below previous air-core intercepts.
6m @ 1.1 g/t Au from 180m to EOH in 25IWBRC0041, confirming mineralised structure at depth.
Mineralisation interpreted to have sub-vertical geometry with ~30m apparent width – open along strike and at depth.
Further five RC holes completed with results pending, designed to test the 2.2km Arrakis trend.
Diamond drilling planned to re-enter and extend 25IWBRC0041, supported by heritage surveys clearing drilling lines across the prospect.
Exploration Context
Arrakis is part of the Caladan target area, located 60km south of Jundee (ASX: NST) and just north of the Siona discovery, within the Yandal Greenstone Belt. The current drilling program was designed to test mineralisation continuity in fresh rock below significant air-core intercepts, which had defined a +2.2km mineralised corridor (Figure 3).

Geological Observations
Mineralisation in 25IWBRC0040 is hosted within a strongly foliated, sheared, and altered mafic-derived unit. High-grade zones are associated with intense silica-albite-carbonate alteration, quartz veining, and up to 5% disseminated pyrite/arsenopyrite (Figure 4). Lower-grade envelopes are marked by sericite alteration with minor veining.

Yandal Resources’ Managing Director, Mr Chris Oorschot, commented:
“In a region where gold remobilisation within the regolith profile is common and complex, fresh rock tests represent a significant milestone in de-risking and progressing exploration targets. These first results demonstrate significant primary fresh rock mineralisation, confirming the discovery of a new mineralised system at Arrakis and the capacity for this system to be large in scale. Well done to the Yandal team, whose resolve and focus on executing the long-term exploration strategy have been paramount to this success.
The Arrakis trend has been defined over more than 2.2km based on 400m and 800m spaced air-core lines. The impact of this discovery will be determined with further results and as exploration is progressed; however, the discovery potential is substantial when you consider the scale of the trend, and the limited and broadly spaced nature of current drilling. Our priority going forward is simple: to confirm the extent of primary fresh rock mineralisation across the 2.2km of strike.
With one heritage survey complete and a second scheduled for the end of September, Yandal will soon have a significant amount of drilling positions available from which to progress the Arrakis discovery.”
Next Steps
Yandal has already completed one heritage survey, clearing 200m spaced lines, and has a second survey scheduled for late September to clear 100m spaced lines, giving flexibility for follow-up drilling. Immediate exploration plans include:
Diamond drilling to extend 25IWBRC0041.
RC drilling on 200m spaced lines along strike to the northwest and southeast.
Integration of geological observations with assay results to refine targeting across the 2.2km trend.
Looking Ahead
With a strong cash position and a fully funded program, Yandal is maintaining an aggressive exploration schedule through the remainder of 2025. Near-term news flow will include:
Results from the five remaining RC holes at Arrakis.
Mobilisation of a diamond rig in October.
First results from AC drilling at the New England Granite target.
Completion of the Gordons Gold Project sale agreement for A$2.81M in cash and shares.
Samso Concluding Comments
The confirmation of a new primary gold system at Arrakis is a meaningful outcome for Yandal Resources. Fresh rock intercepts of this scale are rare, and they represent more than just a continuation of air-core success – they show that the mineralised system is robust and likely to persist at depth.
From an investor perspective, this discovery sets Yandal apart in the Yandal Belt, where brownfields exploration can often be hit or miss. The continuity of mineralisation over 2.2km of strike offers leverage, and with further RC and diamond drilling on the way, the next set of assays could be a real catalyst.
Geologically, the alteration style and sulphide association support the presence of a well-developed hydrothermal system. If step-out drilling continues to deliver similar grades and widths, we may be looking at the foundation of a significant resource.
As with all early-stage discoveries, patience is key. Investors should watch for upcoming results, pay attention to how the geometry of mineralisation is refined, and track how Yandal systematically tests the full strike length. This is where long-term value is created.
The Samso Way – Seek the Research
Always look beyond the first announcement. Discovery confirmation is only the beginning–track how Yandal Resources continues to step out along strike, extend depth continuity, and integrate geological and geophysical data into the model before forming a long-term view.
