Aeris Reports Multiple High-Grade Copper Intersections Extending Tritton Resources

Exploration Success at Avoca Tank

Aeris Resources Limited (ASX, AIS) has delivered an encouraging update on its underground drilling programs at the Tritton Operation, located in central New South Wales. The company reported multiple high-grade copper intersections at the Avoca Tank deposit, extending mineralisation both up-dip and down-dip beyond the current Mineral Resource. These results suggest a potential increase in the mineable inventory at this key deposit.

Notably, drill holes such as ATGC311 and ATGC245 returned impressive copper grades exceeding 6% over significant widths, accompanied by gold and silver credits. The complex geology of Avoca Tank, characterised by multiple sulphide lenses with variable orientations, has historically challenged resource definition. However, the latest drilling, conducted on a nominal 40m by 40m spacing, is refining the geological interpretation and confirming continuity of high-grade lenses.

Discovery of a New Mineralised Trend

Beyond extending known mineralisation, Aeris has identified high-grade copper mineralisation outside the previously interpreted mineralised corridor at Avoca Tank. Drill holes ATEL127 and ATEL128 intersected substantial copper grades over notable intervals, hinting at a potentially new mineralised trend. This early-stage discovery will be a focus for follow-up drilling commencing in January, aiming to delineate the extent and economic significance of this new sulphide lode.

Thicker Mineralisation at Budgerygar

At the Budgerygar deposit, resource definition drilling has yielded thicker than expected copper sulphide intersections within the current Inferred Mineral Resource. Holes BDGC155 and BDGC156, for example, returned mineralised widths exceeding 20 metres with copper grades around 2%. These results not only enhance confidence in the resource but also suggest potential for upgrading resource classification from Inferred to Indicated.

Two underground drill rigs are actively testing down-dip extensions at Budgerygar, with results anticipated in the coming quarter. The proximity of these mineralised zones to existing underground infrastructure positions them well for near-term mine development and production growth.

Strategic Drilling and Future Outlook

Aeris currently operates four underground drill rigs at the Tritton Operation, targeting extensions and repetitions of mineralisation at Avoca Tank and Budgerygar, as well as exploration at other deposits including Tritton and South Wing. The company emphasises that current mine plans do not yet incorporate these exploration successes, but any additional mineralisation identified close to existing infrastructure could provide valuable near-mine growth opportunities.

Executive Chairman Andre Labuschagne expressed optimism about the drilling results, highlighting their potential to increase mineable inventory and extend high-grade ore production. The company’s methodical approach to drilling, combined with detailed geological modelling and assay verification, underpins a robust exploration program aimed at sustaining and growing production at Tritton.
