Twenty Seven Co. Limited (ASX: TSC) has commenced a new, state-of-the-art helicopter-borne AEM survey over a large part of the company’s Rover Project near Leonora in Western Australia.
CEO Ian Warland said the important survey will focus primarily on VMS targets.
He said the two main objectives of the AEM work are to:
- Survey the Harmonic and Creasy 2 VMS prospects for conductors that may indicate sulphides at depth or along strike of known mineralisation plus other priority areas for an AEM response; and
- Survey over 44km of the Cook Well and Maynard Hills greenstone belts, which are largely under shallow cover but contain several conceptual targets previously identified from analysing historic aero-magnetic data.
“The AEM survey will cover circa 90% of the greenstone belts in the southern half of the Rover Project, including known areas, and deliver TSC high quality data to facilitate formulating VMS targets for test drilling.
This is an extremely exciting phase of TSC’s exploration campaign that continues to build on the successful RC drilling programme undertaken in late 2019, which identified two VMS signatures and a shallow high-grade gold discovery.”
Mr Warland said the new Resolution Geophysics’ advanced Xcite technology being deployed for the AEM survey, has an excellent depth penetration to detect conducive bodies undercover.
“Notably, it has been successfully utilised by other explorers across the region to identify VMS mineralisation.”
Once the data has been collected and processed by NRG it will interpreted by geophysicist for potential AEM anomalies associated with sulphide mineralisation. Final interpreted results are expected in March.
Mr Warland said exploration at the Rover Project is being fast-tracked, with the key items over the next quarter including the next phase of RC drilling on priority gold and VMS targets.
