Infill Soil Sampling at Dundas to Further Define Lithium Drill Targets

Lightning Minerals (L1M or the Company) is pleased to announce the start of a targeted infill soil sampling program at its Dundas lithium project in Western Australia. The program is designed to infill the existing geochemistry program which was completed on a grid spacing of 400m x 400m and will consist of approximately 500 samples.


A number of areas of interest were identified in the previously completed regional soil sampling program, particularly on Dundas North tenements E28/3027 and E28/3028 where broad lithium in soil anomalism was identified across an area of 35km2 and up to 147ppm Li1.

HIGHLIGHTS

  • Infill soil sampling program of ~500 samples to further test previously identified lithium in soil anomalism of up to 147ppm Li1
  • Dundas North tenements to be tested across three large lithium targets up to 35km2, as identified in March 2023. Sampling to be completed down to granularity of 200m x 100m in some areas
  • On-ground works at the Company’s Brazil lithium projects in Lithium Valley is in progress with results expected imminently

Lightning Minerals Managing Director Alex Biggs said, “It’s good to be getting back to our works at Dundas following a period of review. We are focusing on areas of interest that have been previously identified as containing lithium in soil anomalism. Our work program is focused and targeted and will allow us to identify appropriate drill targets for a future exploration program. The infill soil sampling on our Dundas North tenements is of particular interest as it allows for us to develop higher confidence drill targets across the project areas. As much as our focus is on Brazil and our accelerated exploration on those projects it is important that we further our efforts at Dundas also particularly as we have gained significant knowledge of the region since our works began there in 2022. The Company now possesses lithium exploration potential in three of the strongest jurisdictions globally for the commodity which sets us up well for success as we move forwards.”

 

Dundas North Infill Soil Sampling

 

Phase 1 soil sampling was completed during Q1 and Q2 of CY2023 with samples collected on a nominal 400m x 400m grid across the tenements, with analysis completed by LabWest Minerals Analysis (LabWest). Analysis utilised the Ultrafine + (UFF+) method with chemical analysis for a suite of 62 elements including lithium and associated pathfinders typically used for identification of lithium-caesium-tantalum (LCT) mineralisation.

The tenor of background lithium level within the project area and the Mt Belches lithological unit appears to be approximately 40-60ppm lithium. The elevated zones returning multiple samples with values above 80ppm lithium and up to a peak result of 147ppm lithium. Results are thought to provide sound vectors toward potential mineralisation as the elevations are clustered and are proximal to suitable granitic protoliths within the ‘goldilocks zone’ for LCT pegmatite mineralisation. The ‘goldilocks zone’ is typically estimated to be between 2km and 10km from the source granitic body.

This geological setting therefore requires follow up exploration works to ascertain the source of the anomalies and forms the basis of the infill soil sampling program as shown in Figure 1. Infill sampling will be completed down to a granularity of 200m x 100m.

Dundas South Infill Soil Sampling

Soil sampling will also be undertaken at the Dundas South project area following up zones of interest identified by the regional soil program. Grids of differing resolutions will be completed across tenements E63/2028, E63,1932, E15/1748 and E63/1993 down to a minimum of 200m x 200m. Targeting criteria in these areas focus mainly on existing results for lithium and its pathfinder elements identified during the reginal program (as reported in ASX Announcement 23 March 2023), but also aim to assess gold/nickel potential as the genetic models can share attributes regarding lithologies, geochemistry and rheology. The planned sites are shown on Figure 2 below, modifications may be undertaken in the field as guided by the supervising geologist.

Top 3 US Lithium Stocks of 2025

As the global economy shifts toward electrification and clean energy, lithium has emerged as a cornerstone of the energy transition, and the US is racing to secure its place in the supply chain.

Lithium-ion batteries are no longer just critical to electric vehicles (EVs); they're becoming vital across sectors to stabilize power systems, particularly amid growing reliance on intermittent renewables.

According to Fastmarkets, demand for battery energy storage systems (BESS) is accelerating, driven by data centers, which have seen electricity consumption grow 12 percent annually since 2017.

Lithium Market Update: Q2 2025 in Review

The second quarter of 2025 brought more downward pressure for lithium prices, as values for lithium carbonate continued to contract, slipping to their lowest level since January 2021.

After starting the year at US$10,484.37 per metric ton, battery-grade lithium carbonate rose to a year-to-date high of US$10,853.85 on January 27. Prices sank through Q1 and most of Q2, bottoming at US$8,329.08 on June 24.

Ekin Ober on Why AI Could Be Mining’s Most Valuable Tool Yet

For Ekin Ober, bringing generative artificial intelligence (AI) to the critical metals sector through her work at Aethos Labs wasn’t just about technological innovation — it reshaped how she thinks about strategy and sustainability in mining.

Now a principal at Kinterra Capital, Ober applies that broad, cross-disciplinary lens to investment decisions, emphasizing the importance of digital fluency, stakeholder alignment and long-term viability.

Her experience helps her identify operational bottlenecks and social license challenges early — essential in guiding assets like nickel and copper projects from concept to production.

Chris Berry: The West Must Invest in Refinement Now or Fall Further Behind

China’s grip on the battery metals sector has drawn increasing scrutiny in recent years as nations confront growing concerns around supply chain risk and resource security.

Through a blend of domestic output and aggressive overseas investment, particularly in Africa and South America, Chinese companies now command a significant share of upstream supply.

The country is responsible for roughly 60 percent of global rare earths production and controls over 70 percent of cobalt supply through its stakes in mines across the Democratic Republic of Congo.
