Aureka’s Irvine Project Drills 0.3m at 183g/t Gold, Boosting Resource Prospects

Breakthrough Assay Results at Irvine

Aureka Limited has announced a remarkable milestone in its ongoing exploration at the Irvine Gold Project in Victoria, Australia. Partial assay results from diamond drill hole RD048 have revealed a 0.3-metre intercept grading an extraordinary 183 grams per tonne (g/t) gold, the highest-grade assay recorded at the project since its discovery in 2017. This intercept is part of a broader 10-metre zone averaging 12.1g/t gold starting from 413 metres depth, underscoring the presence of multiple visible gold occurrences.

Significance of the Tenacity Hanging Wall Fault

The high-grade intercepts are associated with the newly identified Tenacity Hanging Wall Fault, a geological structure that has emerged as a priority target for further exploration. The fault hosts visible gold and substantial sulphide mineralisation, predominantly arsenopyrite, which is believed to enhance gold grades through increased permeability and fluid flow. The discovery of this structure and its mineralisation potential could be pivotal in expanding the current inferred resource at Irvine, which stands at approximately 304,000 ounces at 2.43g/t gold.

Ongoing Drilling and Resource Expansion Potential

Drilling remains active, with hole RD047 also returning encouraging partial results, including intercepts of 0.7m at 13.9g/t and 0.3m at 25.2g/t gold. These findings reinforce the potential for high-grade lodes within the Resolution resource area. The current program aims to infill and extend mineralisation along the Tenacity Hanging Wall Fault and adjacent structures, with the goal of growing the mineral resource beyond its current limits.

Advanced Analytical Techniques and Geological Modelling

Aureka has employed PhotonAssay technology for sample analysis, complemented by rigorous quality assurance protocols. The geological team has updated the structural model for the Resolution prospect, refining the understanding of mineral controls and fault interactions. This enhanced model supports targeted drilling strategies designed to unlock additional high-grade zones and improve resource confidence.

Strategic Location within a Prolific Gold Corridor

The Irvine Gold Project is situated within Victoria’s renowned Stawell Gold Corridor, a region with a rich history of gold production and proximity to the operating Stawell Gold Mine. The project’s geological setting, characterized by steeply dipping sheared basalt and meta-sediment contacts, is conducive to gold mineralisation. Aureka’s continued investment and exploration efforts position the company to potentially capitalize on this prolific gold province.
