It’s anything but an old school nickel hunt at Grey Dam

Carnavale has pulled out the big guns with a ground-based moving loop electromagnetic survey (MLEM) to delineate Kambalda-style nickel sulphide drill targets at its Grey Dam project in WA.
CEO Humphrey Hale’s team are seeking targets associated with five distinct nickel-copper soil anomalies identified by Ultra Fine Fraction (UFF) soil sampling, which was carried out – in conjunction with the CSIRO the survey includes coverage of an historical drill hole with anomalous nickel results.
The MLEM roll-out comes hot on the heels of a passive seismic survey which indicated the target area’s depth of cover and regolith profile wouldn’t impede the ground-based EM surveys.
Carnavale Resources’ (ASX:CAV) interest in the project’s nickel potential has been supported by Ardea Resources’ (ASX:ARL) recent Kambalda-style nickel sulphide discovery at Emu Lake just 24km along strike in the same geological mafic-ultramafic sequence to the northwest.
“Work continues in earnest at our highly prospective Grey Dam nickel sulphide project searching for Kambalda style nickel sulphides under cover,” chief executive officer Humphrey Hale.
“Our work with CSIRO on the UFF soil sampling technology has helped CAV identify many new anomalous zones along the mafic/ ultramafic sequence that require further exploration.
“As a result, CAV is on the ground with a substantial, ground based MLEM survey searching for EM conductors that could represent concealed massive nickel sulphides.”
Grey Dam lies within the Norseman-Wiluna greenstone belt, which hosts several major mines.
The northern area of the project is covered by transported sheetwash and alluvial material that has deterred previous explorers from investigating this terrain as it was difficult to explore the area using traditional soil sampling techniques.
Carnavale may have sidestepped this concern by leaning on UFF soil sampling that Australia’s peak science body CSIRO is evaluating for its usefulness in identifying target mineralisation under areas of cover.
While the CSIRO continues to optimise information produced by the UFF soil programs, the work had already identified five nickel-copper anomalies that are the focus of the current MLEM survey.
