Native Mineral Resources Holdings Limited (ASX: NMR) has recently completed a high-resolution airborne geophysical survey for a total of 4362-line kilometres at a 25m line spacing and 25m sensor height at the Arcoona Project in Western Australia.
This new dataset has been reviewed in context of existing information from the region and at least eight new target areas have been identified for an immediate follow-up sampling campaign.
The principal aim of the survey was to help NMR interpret the potential presence and extent of previously inferred greenstones (igneous mafic volcanics) at several locations on the tenement, but with a particular focus on the southern edge where previous exploration has not been carried out.
The survey was successfully completed by professional geophysical acquisition company MagSpec Airborne Surveys Pty Ltd.
“New, previously unrecognised exploration opportunities have been identified on the Arcoona project area,” Managing Director, Blake Cannavo, said.
“NMR will be targeting eight new areas that were pinpointed using the newly acquired airborne geophysical data. NMR couldn’t be more impressed and excited with the geophysical results that have been obtained over the Arcoona Tenement.
“Areas under cover are often forgotten and lack sufficient exploration but this new dataset has provided us (NMR) with the confidence that there are likely to be significant volumes of greenstones under cover, and that these greenstones may hold gold or nickel mineralisation as they do in the same type of rocks in the region.
“The growing evidence of these greenstones, in a target area only four kilometres west of Northern Star’s Carosue Dam, is extremely exciting news and we are looking forward to getting samples and the sample results back as soon as possible. NMR look forward to reporting results from the area in the very near future.”
Survey location and background
The Arcoona project area, 100 km north-east of Kalgoorlie, covers the margins of a large Archaean granite (biotite monzogranite) intrusion with its emplacement interpreted to have been localised by a series of north-west and north-east trending regional structures.
Greenstones are interpreted to bound the eastern margin of the granite intrusion known as the Relief Monzogranite. The tenement is marginal to a secondary granite intrusion and has faulted granite/greenstone contacts. The project area is adjacent to the crustal level Kilkenny–Yilgangi Fault, a major control of mineralisation.
The area is located four km from Northern Stars’ 4.2Moz at 2.0g/t Carosue Dam project.
The target rocks at Arcoona are referred to collectively as “Greenstones”. NMR will be targeting mineralisation associated with the greenstones as well as the structures that penetrate from the greenstones into the adjacent monzogranite.
