Intersects High-Grade Copper In First Two Holes In NSW
Aeris Resources Limited (ASX:AIS) has intersected high-grade copper in its first two hole at the Constellation deposit, located within the company’s 100% owned Tritton tenement package in New South Wales.
Executive Chairman, Andre Labuschagne, said the early assay results are very exciting.
“Not only are we getting high grade copper hits but the multiple EM plates remain open,” Mr Labuschagne said.
“2020 has been both a challenging and rewarding year for Aeris and the discovery of Constellation has been a great way to finish the year.
“I am looking forward to see how the Constellation deposit evolves over the course of 2021 as the drill program continues.”
Mr Labuschagne said the drill programme has now paused for the Christmas break and will recommence in early January.
Assay results hole TAKD001
Diamond drill hole TAKD001 was the first hole drilled at the Constellation deposit. TAKD001 was designed to intersect the larger ~250m x ~250m EM plate, 150m below surface. The drill hole intersected a 19.95m interval grading 2.41% Cu, 0.64g/t Au and 4.6g/t Ag from 197.2m down hole.
Within the 19.95m thick sulphide package there are three distinct domains, which differ in both sulphide texture and content. The domains are summarised below:
1. 197.20 metres to 202.80 metres: Strongly disseminated to semi-massive pyrite. Pyrite forms euhedral crystal grains up to 5 mm in size. Chalcopyrite forms irregular blebs and erratic stringer veins. The interval is strongly silicified.
· 5.6m @ 1.43% Cu, 0.53g/t Au, 2.4g/t Ag
2. 202.80 metres to 209.60 metres: Chlorite and sericite altered interbedded turbidite sediments (shale and sandstone). Sulphide content is significantly less and dominated by sparse <1cm diameter blebs of chalcopyrite.
· 6.8m @ 0.66% Cu, 0.35g/t Au, 0.9g/t Ag
3. 209.60 metres to 217.15 metres: Bands of massive sulphides (pyrite and chalcopyrite) interlayered with turbidite sediments. Sulphide bands are generally less than 1 metre thick.
· 7.55m @ 4.71% Cu, 0.99g/t Au, 9.2g/t Ag TAKD002
Diamond drill hole TAKD002 was designed to intersect the smaller EM plate defined from the ground EM survey, approximately 300m west of the larger plate targeted by TAKD001.
TAKD002 intersected a 3.55m thick massive sulphide interval from 61.05m down hole. Copper minerals identified include chalcopyrite, chalcocite and minor malachite and azurite. The presence of secondary copper minerals (chalcocite, malachite and azurite) indicates the drill hole intersection is associated with a supergene enriched copper halo below the base of oxidation. Reported assay results returned from the massive sulphide zone are:
· 3.55m @ 22.56% Cu, 2.57g/t Au, 16.1g/t Ag
A down hole EM (DHEM) survey at TAKD002 has been completed. Results from the survey identified two EM conductors.
The first conductive response between 60 metres to 65 metres down hole is associated with the massive sulphides intersected in TAKD002. The modelled plate is ~15m x ~15m and modelled with a high conductance (~5,000S).
The second conductive response is larger (20m x 60m) and located 15 metres off- hole, south, from TAKD002. The modelled conductance (10,000S to 20,000S) is exceptionally high for conductive bodies modelled within the Tritton tenement package. Current thinking is the off-hole EM conductor is likely to be massive sulphides due to the extremely high conductance and spatial location adjacent to the massive sulphides intersected in TAKD002.
