Aurelia Metals Uncovers New High-Grade Lenses at Nymagee Mine

Exploration Breakthrough at Nymagee

Aurelia Metals Limited (ASX – AMI) has announced a significant step forward in its exploration efforts at the historic Nymagee Mine in Central West New South Wales. The company’s recent drilling program has not only confirmed the position of the previously identified Nymagee North lens but also uncovered two new mineralised lenses named Lazer and Metropolitan. These discoveries highlight the potential for substantial resource growth in a region with a rich mining heritage.

New Lenses and Enhanced Mineralisation

The Lazer lens, located approximately 200 metres east of Nymagee North, and the Metropolitan lens, situated between Nymagee Main and Nymagee North, were identified through targeted resource expansion drilling. Notably, the Nymagee North lens was extended by about 50 metres to the north, with drillhole NMD114W1 revealing elevated gold grades alongside copper, zinc, lead, and silver. This polymetallic signature is particularly encouraging as it suggests a richer and more complex mineral system than previously understood.

Drill results from the Lazer lens included a 7.0-metre intercept grading 2.2% copper and 22 grams per tonne silver, with higher-grade zones within that interval. The Metropolitan lens, though narrower, showed promising copper and silver grades and remains open in all directions, indicating further exploration upside.

Strategic Implications and Ongoing Work

Andrew Graham, Aurelia’s Chief Development and Technical Officer, emphasised the significance of these findings, noting the science-led approach underpinning the exploration strategy. The higher gold tenor at Nymagee North contrasts with the historically minor gold content at Nymagee Main, potentially adding new economic dimensions to the project.

Drilling continues with a focus on down-dip extensions and electromagnetic conductor targets identified in recent surveys. A further geophysical survey is planned for November 2025 to refine drilling targets. These efforts aim to define an economically mineable resource, with the results feeding into the company’s 2025 Mineral Resource and Ore Reserve update scheduled for release later this month.

Context Within the Cobar Basin

The Nymagee deposit sits within the prolific Cobar Basin, a region known for structurally controlled, polymetallic mineralisation. Aurelia’s ownership of 95% of the relevant mining leases and exploration licences, alongside a 5% partner, positions the company well to capitalise on these discoveries. The deposit’s geological setting; characterised by steeply dipping quartz-sulphide breccias and complex folding; has historically presented exploration challenges that Aurelia’s modern techniques are now overcoming.

With a history of intermittent exploration by various companies over the past century, Aurelia’s recent work represents a new chapter in unlocking Nymagee’s potential. The polymetallic nature of the mineralisation, including significant copper, gold, zinc, lead, and silver, aligns with the company’s broader base metals and gold focus in the region.
