Aeris Resources Ltd’s (ASX:AIS) diamond drill hole TAKD019 has intersected a 60-metre thick zone containing variable quantities of sulphides (pyrite with lesser chalcopyrite) from 140 metres downhole at the Constellation deposit, within the Tritton tenement package in New South Wales.
The significant sulphide intersection from TAKD019 is materially greater than any other drill intersection recorded at Constellation to date.
It is not yet clear why the sulphide package is significantly thicker in TAKD019, or how it correlates with sulphide intersections in the surrounding drill holes.
To ensure the entire mineralised system around TAKD019 is defined it is likely the surrounding RC drill holes will require extending. A review of the completed RC drill holes is underway.
“TAKD019 is particularly exciting”
Aeris executive chairman Andre Labuschagne said: “Constellation continues to provide exciting results from both the drilling program and the DHEM surveying.
“The 60m sulphide intersection in TAKD019 is particularly exciting, however further drilling is required to understand its significance in relation to the other drilling results, both up-and-down-dip from its location.

“The RC drill program has surpassed our expectations. Intersecting oxide and supergene copper mineralisation from near surface to approximately 130m below surface, over a 120m long strike length, is a fantastic outcome.
“The mineralised system has now been traced approximately 850m down plunge and between 120m to 150m along strike, from 5m below surface.
“The Constellation deposit is shaping up as a copper rich system with clear open pit opportunities.”
Potential large chalcocite dominant mineralised system
Diamond drilling at the Constellation deposit has continued to focus on testing the larger MLTEM (moving loop transient electromagnetic) plate.
Of the 19 drill holes completed to date, 17 have targeted this MLTEM plate.
Results from the RC program indicate the thicker and higher conductance ‘core’ identified from the two modelled near-surface EM plates is part of a larger chalcocite dominant mineralised system.
This is an encouraging result highlighting the potential to extend the supergene enriched chalcocite horizon further south with additional drilling in areas which did not detect an EM response.
