Antares Metals says it has identified a previously unrecognised, district-scale copper mineralisation zone at the Cromwell prospect within its Mount Isa North project.
Surface rock-chip sampling has returned copper grades up to 22 per cent in the area, with further exploration planned.
“AM5’s commitment to targeted field activities and ‘out of the box’ thinking has led to the discovery of a 9km-long mineralised structural corridor at the Cromwell prospect,” chief executive officer Johan Lambrechts said.
“The discovery was made by field geologists making critical observations that led to the identification of a district-scale mineralised area not previously identified.
“The subsequent set of excellent sample results reveals the fantastic potential of the Cromwell prospect and the large scale of the mineralisation footprint.
“Cromwell certainly warrants further field and geophysical activities to identify potential mineralisation hot spots.”
Antares said 81 rock chip samples were collected at Cromwell, with about 17 per cent returning copper values above 2 per cent copper. About 36 per cent returned copper values above 1 per cent.
Antares – formerly NickelSearch – late last year acquired tenements covering 2003sq km of ground held by Capella Metals and Bacchus Resources, collectively dubbed the Mount Isa North project.
