ASX-listed minerals explorer Coolabah Metals (ASX:CNH) has launched a reverse circulation (RC) program located at its Coolabah Licence, near Girilambone in New South Wales.
The company reports the drillholes are designed to test subtle electro-magnetic (EM) targets identified by the HeliTEM2 airborne EM survey completed in July 2022, some 12km northwest of Girilambone.
Coolabah completed processing and interpreting EM data obtained from the HeliTEM survey and 8 anomalies have been delineated from the results and the anomalies have been prioritised.
The 2 highest priority EM targets have been modelled along with a 3D inversion model of the magnetics; one of the two subtle EM conductor plates (Manchester) displays a very close spatially relationship to the modelled magnetic anomaly. The modelled EM anomalies are spatially associated with the magnetic high and surface rock chip samples up to 5,500ppm copper.
The current RC program at Coolabah EL9287 is targeting the two modelled EM conductors associated with the magnetic high.
Coolabah reports ground truthing and reconnaissance work is currently being conducted over additional anomalies identified by the recent HeliTEM survey. The company commissioned Xcalibur Multiphysics to conduct the 996-line km HeliTEM survey, covering a total area of over 210km-square square, well over half of the entire tenement (EL9287).
The company aimed at utilising an airborne EM survey to determine basement conductors, potentially representing Besshi Style massive to semi-massive sulphide accumulations similar to the Girilambone district deposits.
Coolabah Metals is an ASX-listed minerals explorer with a focus on copper, gold, and base metal assets throughout Australia.
