Estrella Resources (ASX:ESR) is delineating the next stage of exploration for ‘precise’ drill targets at the Carr Boyd Nickel Project in Western Australia, following receiving further results from an Audio-Frequency-Magnetic (AFMAG) survey.
Survey technology group Expert Geophysics is continuing to process data acquired from the project, alongside a series of resistivity depth imaging (RDI) sections throughout the survey area.
The $10.55 million market capitalisation company reports the RDI sections are interpreted to reveal Carr Boyd’s geology to a depth of around 600m below surface and provide ‘greater’ detail on the orientation of the anomalies first identified through Expert Geophysics’ initial Target electromagnetic (EM) survey.
Estrella Resources Managing Director Chris Daws says the company has gained further detailed information to develop clear-cut drill targets, which aims to unlock additional nickel sulphide deposits.
“We are dealing with high levels of contrast between the low-resistance host rocks and other high-resistance rocks, such as granite within the project. As a result, we can map the prospective rocks in 3 dimensions with a strong degree of certainty.

Further processing and refinement of the TargetEM and Audio-Frequency-Magnetic time-domain data anticipated, but even this first batch of data is highly useful as we continue to map out the next stage of exploration at Carr Boyd.”
Estrella is now able to interpret that the Colreavy komatiite appears to dip towards the east, while the Carr Boyd pyroxenite plunges vertically.
The RDI data, previous seismic survey data and current TargetEM bedrock anomalism will be used together to model the project intrusion’s internal basal contact to prioritise drill-ready targets.
The Carr Boyd project covers the Carr Boyd Layered Complex — a 75km-square mafic igneous complex which hosts nickel and copper sulphide occurrences. The project lies north of Kalgoorlie, Western Australia.
Estrella Resources is a diverse Western Australia-based company focused on exploring and developing nickel projects.
As of 30 September 2023, the company had $108,000 cash and cash equivalents at hand, according to its latest quarterly report. Post-quarter end, Estrella raised $1.65 million via a placement.
