Aurumin Limited announced drilling targeting lithium bearing pegmatites at its 100% owned Mt Palmer Project is planned to commence next week. Aurumin's Ultrafine soil sampling programme at Vickers Find South has been completed, with the grid infilled to a spacing of 100m x 200m, and all samples submitted to the laboratory for analysis. A preliminary XRF assessment of these samples using Portable Spectral Services' proprietary Lithium Index Calibration has highlighted promising targets at the Vickers Find South prospect.

Some of these targets are coincident with historically drilled pegmatites, interpreted to be flat lying, and that were only sampled for gold. Aurumin now plans to drill test the targets where pegmatites have previously been identified. The initial Programme of Works has been approved with the drilling contractor scheduled to commence work the week commencing 25th April for a 1,000m to 1,500m orientation programme.

A further Programme of Work is in the process of being submitted for a planned second phase of drilling to target additional areas of surface anomalism identified from the soil sampling programme. Aurumin has completed an Ultrafine sampling programme at the Vickers Find South prospect at Mt Palmer. A total of 735 samples, exclusive of QAQC samples, were collected during the programme (phase 1 and phase 2) reducing the sample spacing to 100m by 200m.

All samples have been submitted to Labwest for multielement analysis with the results expected mid to late May. Prior to submission to Labwest, a preliminary assessment was completed by Portable Spectral Services (PSS) for lithium prospectivity based on an in-house developed Lithium Index Calibration using a desktop XRF Bruker CTX instrument. The Lithium Index acts as a proxy for lithium concentrations as pXRF instruments are unable to directly detect lithium.

The Lithium Index uses detectable elements which correlate to Lithium-Cesium-Tantalum (LCT) pegmatites, i.e., Ga, Rb, Nb, Cs, and Ta, along with additional elements used to evaluate the fertility of granites. The additional infill sampling has firmed up the initial targets identified (reported ASX, 24th March 2022). A number of these targets consist of surface anomalism coincident with historically logged pegmatite in drilling with intercepts up to 50m downhole.

Aurumin now plans to drill test targets VFSA and VFSB. The initial Programme of Works (POWs) were submitted prior to preliminary soil results becoming available and were based on where pegmatites have been logged in historical drilling. These POWs cover the VFSB target and have now been granted.

Aurumin has engaged a drilling contractor to drill a orientation first pass reverse circulation (RC) programme of 1,000m to 1,500m to assess these identified pegmatites. The programme is planned to commence the week beginning 25th April. A POW submission is being completed for the high priority VFSA target, identified from the Lithium Index Calibration.
