Aeris Resources Ltd (ASX:AIS) identified more than a dozen priority targets at the Tritton Operations in western New South Wales last year, leveraging airborne electromagnetic (AEM) surveys to investigate the tenure down to 300 metres of depth.
“We continue to be excited by both the greenfields and brownfields copper exploration potential on our Tritton tenement package,” Aeris Resources executive chair Andre Labuschagne said.
“Airborne EM surveys have proven to be an effective method for identifying potential sulphide deposits down to 300 metres below surface and was how we first identified the Constellation deposit.
“The latest AEM program conducted in 2022 has resulted in 14 high potential anomalies being identified.
“Our next step will be to conduct ground-based EM on each of these to determine if they are legitimate bedrock conductors, which we would then test with drilling.”
High-grade copper at Kurrajong
Apart from survey exploration efforts, Aeris has also been drill testing the Kurrajong prospect, where the company has intersected high-grade copper.
Results of note include:
- 18.45 metres at 3.14% copper, 0.30 g/t gold and 6.6 g/t silver from 443.4 metres; and
- 21.2 metres at 2.75% copper, 0.17 g/t gold and 5.2 g/t silver from 488 metres.
“The assays from the Kurrajong drilling program are very encouraging and we expect to report a maiden mineral resource for Kurrajong towards the end of the March quarter,” Labuschagne continued.
“A common characteristic of deposits on the Tritton tenement package is down-plunge continuity of mineralisation.
“Recent drilling at both the Murrawombie and Avoca Tank deposits has identified strong potential for mineralisation at both of these deposits to continue below the current mineral resources.
“Over the last two years, we have embarked on a systematic program to understand the geochemical signatures at each of our known deposits and then use this information to try to identify analogues across our tenement package.
“The planned two-hole drilling program at the 5M7 prospect is a direct result of this work, as we seek to test for potential mineralisation at depth, adjacent to two geochemical anomalies that have been identified.”
