Yandal Resources Limited (ASX: YRL) announced further drilling results from the Arrakis Prospect at its 100%-owned Ironstone Well-Barwidgee Gold Project in Western Australia, reporting that diamond tail hole 26IWBRC0117D returned 24.2m at 1.4g/t Au from 237.8m, including 8.3m at 3.0g/t Au and 3.0m at 5.4g/t Au, and thereby extended the newly defined higher-grade Domain C about 80m down-plunge to an approximate vertical depth of 200m, with the zone remaining open at depth; the company said the result supports an increase in both mineralisation width and grade with depth and builds on previously reported strong Arrakis intercepts including 20m at 8.7g/t Au in 26IWBRC0120, 17.5m at 2.3g/t Au and 17.0m at 1.1g/t Au in 26IWBRC0121D, and 50m at 1.3g/t Au in 25IWBRC0042, with combined data indicating Domain C plunges about 45 degrees to the southwest within a broader Arrakis mineralised system currently defined over more than 1.3km of strike and hosted in a deformed porphyritic dacite intrusive; the announcement also noted pending assays from final diamond tail 26IWBRC0116D, planned follow-up drilling at Arrakis, and supporting geological interpretation that higher-grade mineralisation is structurally controlled and associated with more intense brittle-ductile deformation, silica-pyrite-arsenopyrite alteration and brecciation along intrusive margins.
Key Points
Yandal Resources announced new Arrakis drilling results on 8 September 2026.
Diamond tail hole 26IWBRC0117D returned 24.2m at 1.4g/t Au from 237.8m, including 8.3m at 3.0g/t Au and 3.0m at 5.4g/t Au.
The 26IWBRC0117D intercept extends the newly defined high-grade Domain C by about 80m down-plunge.
Domain C remains open at depth and was intersected at an approximate vertical depth of 200m.
Results indicate an increase in both the width and grade of gold mineralisation with depth at Arrakis.
Previously reported Arrakis results supporting Domain C include 20m at 8.7g/t Au in 26IWBRC0120, 17.5m at 2.3g/t Au and 17.0m at 1.1g/t Au in 26IWBRC0121D, and 50m at 1.3g/t Au in 25IWBRC0042.
Combined drilling suggests Domain C plunges about 45 degrees to the southwest.
Arrakis primary fresh rock mineralisation has been defined over more than 1.3km of strike within the Ironstone Well-Barwidgee Gold Project.
Arrakis mineralisation is hosted in a deformed porphyritic dacite intrusive between pillow basalt and dolerite units.
Yandal said follow-up drilling at Arrakis is warranted and final assays from hole 26IWBRC0116D were expected in September.
