Aureka Limited has intersected multiple occurrences of visible gold within the Walkers Zone structures at the St Arnaud project in Victoria, marking the first time visible gold has been identified in secondary structures at the Comstock prospect.

Diamond drill hole NED035 returned visible gold from as shallow as 18 metres vertically beneath the current pit surface. The program intersected multiple gold grains measuring one to two millimetres in length at 21.7 metres down hole, hosted in bedding-parallel quartz veining. A secondary interval at 61.2 metres down hole—representing an approximate vertical depth of 40 metres—yielded an additional 13 grains measuring between 0.5 and 2 millimetres in length within a three-centimetre-thick quartz vein associated with a larger extension vein set.

The St Arnaud Comstock Project is a former mine site that ceased operations in 1995. The project sits within the broader St Arnaud goldfield, which holds a historical production record of 400,000 ounces at an estimated grade of 15 grams per tonne of gold.

“I'm impressed to see Comstock delivering again with at least two occurrences of visible gold this time located within the pit we have targeted for first production. We drilled seven diamond holes at Comstock in 2025 with significant gold and/or silver results in six of these holes - this repeated success in a previously mined pit demonstrates the value we have at Comstock in the high-grade St Arnaud goldfield where, within 2km of our drill rig location, there is a history of mining 400koz of gold at 15g/t.”

The current drilling is part of a near-term production strategy for Comstock. Aureka advanced this pathway by securing a three-year binding toll milling agreement with the Wedderburn Gold Processing Mill in July 2026 to supply a flexible processing route for ore from its Victorian asset base. Licensing processes for the Comstock operation are currently underway.

Aureka cautioned that visual estimates of mineral abundance and preliminary geological logging are not a proxy for laboratory analysis. Laboratory assay results for the visible gold samples from hole NED035 are expected within three to five weeks.
