Drills Significant High-Grade Copper Intersections At Constellation
Australian copper-gold producer and explorer Aeris Resources Limited (ASX: AIS) has obtained exceptional copper assays in its latest exploration activities at the Constellation deposit, located within the company’s 100% owned Tritton tenement package in New South Wales.
Executive Chairman, Andre Labuschagne, said the high-grade copper mineralisation is thicker than expected within the oxide / supergene zones and remains open along strike to the south.
“The first round of assay results from the RC drilling have exceeded our expectations,” Mr Labuschagne said.
“Intersecting high-grade copper mineralisation within 10m from surface is remarkable.
“The footprint of this near-surface copper mineralisation is also larger than we expected and remains open along strike to the south.”
Significant high grade copper intersections include
- 38m @ 3.72% Cu, 0.36g/t Au, 3.1g/t Ag (from 8m);
- 47m @ 3.90% Cu, 0.96g/t Au, 5.6g/t Ag (from 11m);
- 38m @ 2.91% Cu, 0.47g/t Au, 1.8g/t Ag (from 44m);
- 10m @ 5.48% Cu, 0.83g/t Au, 3.7g/t Ag (from 40m), incl.5m @ 10.77% Cu, 1.56g/t Au, 6.8g/t Ag (from 45m);
- 42m @ 1.56% Cu, 0.92g/t Au, 1.7g/t Ag (from 31m);
- 30m @ 1.47% Cu, 0.47g/t Au, 2.9g/t Ag (from 92m), incl.8m @ 2.58% Cu, 0.53g/t Au, 5.4g/t Ag (from 103m) and 6m @ 3.02% Cu, 1.31g/t Au, 4.7g/t Ag (from 116m); and
- 12m @ 2.58% Cu, 1.41g/t Au, 3.6g/t Ag (from 127m).
The RC drill programme underway at the Constellation deposit and is designed to test the extents of shallow oxide and supergene copper mineralisation first identified from diamond drill hole TAKD002.
The RC drill programme has now defined the oxide and supergene copper footprint approximately 150m along strike and 130m down plunge. Mineralisation remains open to the south.
52 RC drill holes have been completed to date, with assays received for 22 and assays pending on the remaining 30. Two applications to the NSW Resources Regulator have been submitted for an additional 40 RC holes in the adjoining two exploration tenements. The application to complete 19 RC holes in EL8084 has been approved.
Between 10 to 15 RC drill holes intersected water at or within the mineralised horizon and were stopped. Work is currently underway to extend each hole via diamond drilling and once this work is completed the RC drill program will continue on new holes.
Native copper has been observed in some RC holes. The assay results reported do not discriminate between oxide, supergene, native copper or primary copper minerals. Samples through the mineralised zones will undergo more sophisticated analytical techniques to quantify the proportion of oxide, supergene, primary and native copper within.
