Aldoro has started rock chip sampling at the Fairway Corridor target at its Windimurra Igneous Complex (WIC) project, which hosts nickel-copper-PGEs and lithium.

To date the company has sampled around 30% of the high albedo anomalies, with a total of 275 samples collected.

Notably, a high proportion of the samples are from the two known lepidolite areas which visually contain purple micas (lepidolite) – the host for the rubidium and lithium.

Portable X-Ray Fluorescent (pXRF) analysis of 80 samples in the field found all but a handful appearing to be highly anomalous in rubidium, with a peak reading of 1.71%, and an average of 0.24%.

Aldoro Resources (ASX:ARN) says these results are a preliminary indicator only, and that wet chemistry results from an accredited laboratory are required to confirm.

The rock chip sampling will continue until all of the outcropping pegmatites have been tested, and is expected to be completed by the end of the year.

Follow-up RC drilling planned

The aim of pXRF sampling is to identify the areas with the highest grade rubidium to target with follow-up RC drilling.

This will fast-track the work programs, allowing the company to move into the first phase of drilling – even though wet chemistry results from the laboratory will be several months away.

And while lithium is not detectable by pXRF, Aldoro said that previous analytical work has shown a good correlation between lithium and rubidium.
