Yandal Resources Reports 11m at 1.4 g/t Au Extending Arrakis to 1.2km

Expanding the Arrakis Prospect

Yandal Resources Ltd (ASX, YRL) has unveiled further encouraging assay results from its large-scale Caladan air-core drilling campaign, which has successfully extended the Arrakis gold mineralised structure by an additional 400 metres to the southeast. This extension brings the known strike length of the structure to over 1.2 kilometres, with mineralisation remaining open both to the northwest and southeast.

The recent results include notable intercepts such as 11 metres at 1.4 grams per tonne (g/t) gold from 71 metres depth, including a higher-grade 6 metres at 2.3 g/t gold. These findings build on earlier intercepts reported in July 2025, reinforcing the continuity and scale of the mineralised system within the Caladan target area.

Geological Insights and Mineralisation Style

The mineralisation is predominantly hosted within sheared and altered dolerite, a mafic rock type, with the latest drilling also revealing the presence of a felsic intrusive (porphyry) proximal to the mineralised zones, an association not previously documented at Arrakis. This geological setting aligns with the broader Ironstone Well-Barwidgee Gold Project, situated within the highly prospective Yandal Greenstone Belt of Western Australia, a region known for significant gold discoveries.

Yandal’s Managing Director, Chris Oorschot, highlighted the consistency of mineralisation relative to the 3-kilometre Arrakis regolith anomaly and expressed optimism about the potential for further extensions. He noted that the company has completed drilling lines extending 800 metres beyond the current results in both directions, with assay results from 86 additional holes pending.

Program Scale and Next Steps

The Caladan air-core program has now concluded, comprising 132 holes totalling 13,458 metres. To date, results from 46 holes have been received, with the remainder expected over the coming weeks. The company has scheduled follow-up reverse circulation (RC) and air-core drilling for August to test mineralisation at depth and refine the geometry of the host structures.

Complementing the drilling activities, heritage surveys are planned for late August and September to enable closer-spaced drill lines, which will facilitate more detailed exploration across the Arrakis structure and other targets within the Caladan area.

Strategic Position and Funding

Yandal Resources remains well-funded and focused on advancing exploration across its portfolio, including the Caladan and New England Granite target areas. The company’s strategic approach leverages the under-explored nature of the Caladan Fold, a large-scale structural feature analogous in scale to the Kalgoorlie district, which hosts some of Australia’s richest gold deposits.

With a robust cash position and a busy exploration schedule ahead, Yandal is positioned to capitalize on the discovery potential highlighted by these latest drilling results.
