Aldoro Resources Ltd (ASX:ARN) has completed a series of reverse circulation (RC) drilling at its Narndee project to extend the nickel and platinum-group-elements (PGE) footprint of the Western Australian asset.
The company last week announced the discovery of a 40-metre thick zone identified using portable X-ray fluorescence (pXRF) readings, which it has named 'Area 32 Nickel Discovery'.
Area 32 was discovered during drilling of a third diamond hole, NDD0032, part of drill program at Narndee targeting four induced polarisation (IP) geophysical anomalies identified earlier this year.
The original drill program targeting eight holes for 884 metres has now been completed and samples sent for laboratory analysis.
Another eight holes will be drilled to understand the shallow nature of Area 32.
Another nickel anomaly
Additionally, 16 reverse circulation holes for 664 metres have been completed at Four Corner Bore, about 3.4 kilometres southeast of NDD0032, where historical drilling had indicated shallow nickel mineralisation.
Samples are being selected for assaying and are expected to be lodged at the laboratory by the end of the month.
The results can be expected in six weeks.

pXRF vs lab results
Separately, Aldoro said laboratory assay results received for diamond hole NDD0032 on Monday suggest that the pXRF reading announced by the company last week provided a higher nickel grade reading than expected.
The deeply weathered oxidised zone at Area 32 had influenced the pXRF data to an extent where it cannot reliably produce a reading with certainty, it noted.
