Stelar Metals (ASX:SLB) and SensOre Ltd (ASX:S3N) recently completed research under their data sharing agreement, developing innovative lithium targeting tools and deploying the newly completed SensOre NSW data cube. The research revealed new areas of high LCT-pegmatite prospectivity along a NNW-SSE trend. LCT- pegmatites are predicted where previous exploration targeting high-grade tin and tantalum overlooked LCT pegmatite potential. Potential was identified in the central and northern project areas, as well as new opportunities around the source granite/granite-gneiss complex in the south. Direct targeting from radiometric data is encouraging and work to integrate results with the magnetic data is on-going.
Highlights
- SensOre and Stelar Metals have completed their research efforts on the highly prospective Trident lithium tenements near Broken Hill (NSW), identifying new areas of prospectivity at surface, as well as deeper concealed targets
- The collaboration looked at deploying AI/ML applications on surface geochemistry and high- resolution geophysical techniques in support of lithium exploration
- SensOre received funding from the NSW government worth $318,000 to assist with the data cube build. The NSW data cube is now available for targeting by SensOre clients
- Innovative AI and ML predictive methodologies were established over large areas of New South Wales for identifying pegmatites as sources of economic lithium, tin, tantalum and caesium
SensOre CEO Richard Taylor said: "We are pleased to have such stunning initial results from our first targeting runs deployed for Stelar Metals. The new innovative tools, validated through field work, open up many new possibilities for SLB. The Stelar project represents the first targeting exercise deploying the recently completed NSW data cube, combining geoscience data across geophysics, geochemistry, drilling and geological data layers with spectacular preliminary results”.

SensOre Adjacency Model for Li Prospectivity
SensOre’s Adjacency Model, AI/ML technology was applied to high-resolution magnetics and 256-channel radiometric data combined with Geochemical Data Analytics to identify extensive prospective areas for LCT- bearing pegmatites. SensOre’s Adjacency Model (SAM) targets spatial contiguity, of geochemical enrichment and/or depletion patterns and geophysical characteristics that surround ore deposits. In this instance, SensOre used mapped occurrences of pegmatites to compute spatial proximity of high-resolution magnetic data and 256- channel radiometric data features to identify pegmatite signatures using advanced ML tools. Once these pegmatite signatures were quantified, they were targeted throughout the rest of the geophysical data across Stelar Metals’ Trident Project. SAM maps identify/confirm and/or predict prospective mineral trends and mineral systems by computing categorical probabilities of adjacency to ore deposits typically labelled as ‘Barren’, ‘Distal’, ‘Proximal’ and ‘Ore’.
SensOre then employed Factor Analysis on multi-element geochemical data collected from pegmatites over Stelar’s Trident Project. This work identified a multielement geochemical signature consistent with LCT pegmatite mineralisation (i.e., Factor 2 positively loaded with Li-Cs-Ta-Sn-Be-Nb) with high factor scores coinciding with high SAM prospectivity probabilities and, as expected, high Li-grades. The targeting coincidence of independent geophysically driven and geochemically driven approaches provides confidence to the identified LCT targets. At Trident, we were able to show that samples exhibiting relatively high Factor 2 loading scores tend to be in the northwestern and south-central areas.

Heritage Clearances Received for Priority Drill Targets at Abbotts North
HIGHLIGHTS
- Heritage clearances have been received for areas covering priority lithium pegmatite targets at the Abbotts North Project.
- Main Buttamiah Prospect now accessible for the February RC program
- Track and drill pad establishment has commenced and RC drilling rig is mobilising to site.
Richard Taylor, CEO of Premier1, said:
“With the receipt of the heritage survey report and the recent approval of the Programme of Work applications by the Department of Mines, Industry Regulation and Safety, we now have in place all the environmental and heritage approvals required for the first drilling program at Abbotts North. I thank the traditional owners of Abbotts North, the Ngoonooru Wajarri, for their advice and involvement in the process.
With site mobilisation having commenced and the RC rig already on its way, this is an important and exciting phase for Premier1.”
Priority Targets
The survey area covers the main Buttamiah Prospect where several parallel lithium bearing pegmatites have been mapped and sampled. The pegmatites strike approximately east west and single pegmatites can be traced in strike over an extended area. The RC program has been designed to test the depth and extent of the mineralised pegmatite field.
There remain further priority targets at the Abbotts North Project based on the latest completion of the first phase of field mapping, rock chip sampling and soil geochemistry in December 2023. The results from the soil survey highlighted areas of interest with anomalous responses comparable to the geochemical signature over the main Buttamiah Prospect (ASX 22 January 2024). Further follow up fieldwork will be conducted to assess these new priority targets and plan for further heritage clearance surveys.
Heritage Survey
The first heritage clearance survey at Abbotts North was completed by Archaeological Excavations Pty Ltd in conjunction with the Ngoonooru Wajarri people, who are the traditional owners of the lands and waters. The survey was conducted over several days, with participants from Archaelogical Excavations, the traditional owners and Premier1.

Programme of Work (“PoW”) approvals have been received from the Department of Mines, Industry Regulations and Safety (“DMIRS”) for 4.92ha of land within Exploration Licence E51/2126 (Table 1).
Premier1 Lithium now has in place sufficient PoW and heritage clearances to conduct RC drilling over the main target areas at the Abbotts North Project. The first drilling program is planned for approximately 2,000m. The focus is to define the continuity and extent of lithium mineralisation evident in rock chip samples taken from surface within the main Buttamiah Prospect.
