Aureka Limited (ASX: AKA) announced that diamond scout hole RD057 at the Irvine Gold Project in Victoria’s Stawell Corridor intersected two new high-grade gold zones 725 metres north-northwest along strike from the 358koz Resolution Lode JORC Mineral Resource, extending the known mineralised footprint toward the Stawell Gold Mine and confirming mineralisation within a previously untested conceptual exploration target. Key intercepts were 4.25m at 1.42g/t Au from 173m including 1.5m at 3.16g/t Au, and 5.65m at 0.83g/t Au from 341.5m including 0.85m at 3.19g/t Au. The mineralisation occurs at basalt-sediment contacts with local faulting, in a structural and lithological setting similar to Resolution, and is supported by induced polarisation and demagnetisation geophysical responses plus elevated surface geochemistry. Aureka said the result validates its exploration model focused on structurally complex areas and second-order structures away from the main Resolution Shear, with ongoing drilling targeting additional lodes, lode extensions and near-surface extensions such as the Tenacity Structure. The company highlighted that Irvine now hosts a 398.3koz inferred JORC resource across the Resolution and Adventure lodes within a growing mineralised system exceeding 5.5km strike length, while updated exploration targets range from 85–197koz for advanced targets and 151–348koz for conceptual targets, supporting Aureka’s ambition to grow Irvine beyond 1Moz.
Key Points
Aureka Limited announced new diamond drilling results from the Irvine Gold Project on 14 October 2026.
Scout hole RD057 intersected two new gold zones 725m north of the Resolution Lode resource.
Key intercepts were 4.25m at 1.42g/t Au from 173m including 1.5m at 3.16g/t Au, and 5.65m at 0.83g/t Au from 341.5m including 0.85m at 3.19g/t Au.
The discovery was made in a previously untested conceptual exploration target supported by geophysics and surface geochemistry.
Mineralisation is hosted near basalt and sediment contacts with local fault margins in a setting similar to the Resolution discovery.
The new zones align with second-order induced polarisation and demagnetisation responses.
The mineralisation lies about 500m south of the Stawell Granite and on trend toward the Stawell Gold Mine.
Aureka said the intercepts validate its exploration model targeting structural complexity and second-order structures distal from the main Resolution Shear.
The Irvine Project currently contains a total inferred JORC resource of 398.3koz gold across Resolution and Adventure.
Aureka stated the Irvine mineralised footprint now exceeds 5.5km strike length and continues to grow at depth, along strike and down plunge.
Updated exploration target ranges for Irvine were 85–197koz for advanced targets and 151–348koz for conceptual targets.
Ongoing drilling is targeting further lodes, lode extensions and near-surface extensions including the Tenacity Structure.
