An airborne electromagnetic (EM) survey is on track to begin this weekend at Aldoro Resources’ (ASX: ARN) Narndee nickel-copper-platinum group elements (PGE) project in Western Australia.
The company today announced UTS Geophysics is mobilising to site with the approximate 932 line km VTEM Max survey anticipated to take eight to 10 days.
This latest news is a further update to the company’s announcement in late October, when it revealed its plan to commence “major exploration efforts” at the Narndee Igneous Complex.
The survey is planned to cover the 137.3sq km predominantly ultramafic core area of the complex, located 400km north-northeast of Perth in WA’s Murchison region.
According to Aldoro, this portion of the complex is believed to show “clear evidence” for a working sulphide mineral system, with numerous historic shallow drill intersections of nickel-copper-PGE mineralisation but limited follow-up work.
The survey aims to improve upon a lower powered airborne EM survey conducted in 2008 by former tenement owner Maximus Resources (ASX: MXR) with more than 50 anomalies identified for reprocessing.
Targets arising from the survey will be followed up with ground geophysics, including gravity, EM, magnetics, and geochemical programs to define drill targets for 2021.
Additional test lines at Mulyeron Hill
In addition, Aldoro is planning to fly several test lines over Mulyeron Hill, at its neighbouring Windimurra project about 30km northeast of Narndee.
The company noted that the area around Mulyeron Hill is complicated by salt pans that may hinder the EM system, but should the test lines prove viable, it will take the opportunity to complete a further 57 line km over this area while the VTEM Max system is in the region.
Mulyeron Hill is one of the few known outcropping predominantly ultramafic portions of the Windimurra Igneous Complex, with historic results showing anomalous values of nickel-copper-PGEs.
Narndee in the spotlight
The company has described Narndee as a “significant focus” from now and into 2021.
The Narndee Igneous Complex has been historically explored by mining majors including BHP (ASX: BHP) and Canadian companies Inco and Falconbridge.
In October’s announcement, Aldoro managing director Caedmon Marriott said the potential of finding a massive deposit at Narndee is a “genuine company-making opportunity”.
“Aldoro will use modern thinking and exploration techniques, with the likes of the planned high-powered VTEM Max survey, to focus on magmatic nickel-copper sulphides and attempt to locate possible constrained magma feeder conduits or chonoliths – host to deposits such as Nova-Bollinger, Voisey’s Bay and Julimar – in this type of layered mafic-ultramafic geology,” he said.
