Flagship Project

Stawell Corridor

Aureka’s Stawell Corridor Project (which incorporates the Irvine and Langi Logan gold projects and five other prospective targets) captures 60 kilometres of a multi-million-ounce gold zone.

The Irvine Project hosts a large Mineral Resource of 398koz at 2.59 g/t Au (100% Inferred, JORC 2012) and an additional Exploration Target of Advanced 85-197koz + Conceptual 151-348koz gold on the margins of a basalt dome only 16km South from the operating Stawell Gold Mine (~five million ounces)1.

Drilling Campaign

Growing the Resource

Aureka is currently diamond drilling the Resolution lode at Irvine, and step-out drilling continues testing extensions beyond the new Resource boundary, plus continued work on the Tenacity Fault discovery.

Irvine highlight drill results include 5.0m @ 10g/t, 9.4m @ 5.3g/t, and 10.8m @ 4.5g/t2.

Aureka’s flagship Irvine Project hosts a large Inferred Mineral Resource (398koz at 2.59 g/t Au) and additional Exploration Target (Advanced: 85-197 koz; Conceptual: 151-348 koz) on the margins of a basalt dome only 16 km south of the operating multi-million-ounce Stawell Gold Mine. In June 2026 the Resource was upgraded by 30% from the 2021 Maiden, driven by drilling success at the Resolution Lode including the high-grade Tenacity Fault discovery reported in late 2025. Diamond drilling continues at Irvine, testing extensions beyond the newly defined Mineral Resource.

South of the Irvine Project lies the high-grade gold discovery Langi Logan on a 14.5 kilometre long basalt dome. Over 120,000 ounces of alluvial gold was historically mined from the nearby Cathcart Central and New Langi Logan shafts. Although the source of the alluvial gold is uncertain, it occurs in close proximity to the Langi Logan basalt dome which the Company believes is an encouraging sign for the occurrence of a potential Stawell-style gold deposit. To the west lies The Morning Bill (Glenlyle) Prospect, a potential epithermal gold-silver system above what is believed to be a deeper porphyry target in the emerging Stavely Arc volcanics.
