Lightning Minerals (“L1M” or “the Company”) is pleased to provide an update for the Dundas South Project and reports assay results for its recent drilling program on tenement E63/2000. The drilling program tested lithium and rubidium targets identified through regional soil exploration work (refer ASX release 9th February). The results demonstrate a continuation of strong lithium and rubidium occurrences (up to 994ppm lithium and 1,834 ppm rubidium at depths of up to 26m.
Highlights
- Positive assays for the Company’s 96 hole, 3,820m Aircore drill campaign1 on tenement E63/2000 have now been received
- Assays have returned elevated lithium values on composite samples with peak results of 994ppm lithium, confirming and increasing the tenor of the previously identified anomalism
- Results highlight three sites of interest which exhibit correlated elevations in lithium and pathfinder elements supporting continued exploration
Strong assay results have continued at the Company’s Dundas South Project within tenement E63/2000 following completion of drilling in February 2024. Results continue to demonstrate the presence of elevated lithium across the project area with strategies now being reviewed to identify the potential source of the anomalous lithium values. The staged approach to exploration across the Company’s Dundas projects continues to build confidence in lithium potential throughout the region.
Lightning Minerals Managing Director Alex Biggs said, “Drilling on E63/2000 has yielded positive results that suggest we are potentially closing in on what might be a source of lithium mineralisation. The staged approach we have taken: geophysics, soil sampling, infill soil sampling and now Aircore drilling have helped us identify the areas of highest importance and we will continue to follow up on these with further targeted drilling. It also demonstrates that this approach to exploration works, while at the same time conserving capital and ensuring maximum value proposition for exploration expenditure.
The Company remains committed to its exploration at its Dundas project and is excited to begin exploration at its newly acquired Caraíbas and Sidrônio projects in Brazil’s Lithium Valley region of Minas Gerais. It is important that we generate optionality in our exploration strategy and we now hold projects in three of the most prospective lithium districts in the world: Minas Gerais, Brazil, Dundas, Western Australia and Quebec, Canada. We remain excited about the Company’s project’s potential and are supportive of the overall lithium thematic”.
Drilling Results for Dundas Tenement E63/2000
During early 2023 Lightning Minerals completed a first pass reconnaissance soil geochemistry program consisting of 1,391 soil samples at its Dundas South Project. Results within tenements E63/2000 and E63/1993 defined a broad lithium in-soil anomaly over an approximate 2.4km x 1.0km area, including a peak result of 218ppm lithium (Figure 1). Infill sampling was then completed to further define anomalism and to delineate drill targets through the shallow regolith and alluvial cover present in the area. The positive results of the infill program were sufficient to support the continuation of exploration activities through Aircore drilling.

The maiden drill program within E63/2000 was then completed in February 2024 and assays have now been received for all samples submitted for laboratory analysis. Results show three sites of interest, these exhibit broadly correlated elevations in pathfinder elements within highly weathered saprolites. Two of the three sites (Drill Traverse 4 and 6, Figure 2) are located on the eastern extents of east west orientated drill lines and will require follow up exploration to continue vectoring toward any potential lithium mineral system that may be responsible for the elevated results.
Samples were collected from all holes using a 4m composite sampling technique from surface. The samples were then submitted to Nagrom laboratories for a full suite of exploration stage low level elemental analysis. Lithological logging via suitably qualified contract geologists reported a range of end of hole (EOH) rock types including mafic volcanics, granites, and metasediments, with some holes ending at hard undifferentiated saprock/saprolite boundaries.

CleanTech Lithium
Overview
CleanTech Lithium (AIM:CTL,FWB:T2N,OTC:CTLHF) is a resource exploration and development company with four lithium assets with an estimated 2.72 million tons (Mt) of lithium carbonate equivalent (LCE) in Chile, a world-renowned mining-friendly jurisdiction. The company aims to be a leading supplier of ‘green lithium’ to the electric vehicle (EV) market, leveraging direct lithium extraction (DLE) – a low-impact, low-carbon and low-water method of extracting lithium from brine.
Lithium demand is soaring as a result of a rapidly expanding EV market. One study estimates the world needs 2 billion EVs on the road to meet global net-zero goals. Yet, the gap between supply and demand continues to widen. As the world races to secure new supplies of the critical mineral, Chile has emerged as an ideal investment jurisdiction with mining-friendly regulations and a skilled local workforce to drive towards a clean green economy. Chile is already the biggest supplier of copper and second largest supplier of lithium.
With an experienced team in natural resources, CleanTech Lithium holds itself accountable to a responsible ESG-led approach, a critical advantage for governments and major car manufacturers looking to secure a cleaner supply chain.
Laguna Verde is at Pre-Feasibility Study stage, which is due to be delivered by Q4 2024. The project is targeted to be in ramp up production from 2027. Laguna Verde has a JORC resource estimate of 1.8 Mt of lithium carbonate equivalent (LCE) while Viento Andino boasts 0.92 Mt LCE, each supporting 20,000 tons per annum (tpa) production with a 30-year and 12-year mine life, respectively. The latest drilling programme at Laguna Verde finished in June 2024, results from which will be used to convert resources into reserves.
The lead project, Laguna Verde, will be developed first, after which Veinto Andino will follow suit using the design and experience gained from Laguna Verde, as the company works towards its goal of becoming a significant green lithium producer serving the EV market.
CleanTech Lithium’s pilot DLE plant in Copiapó was commissioned in the first quarter of 2024. The plant will process brine from both Laguna Verde and Viento Andino to produce lithium chloride eluate, which will then be converted into battery-grade lithium downstream through a third-party partner.
The Company is carrying out the necessary Environmental Impact Assessments in partnership with the local communities. The indigenous communities will provide valuable data that will be in included in the assessments. The company also has two prospective exploration projects.
Llamara project is a greenfield asset and in the Antofagasta region and is around 600 kilometers north of Laguna Verde and Veinto Andino. The project is located in the Pampa del Tamarugal basin, one of the largest basins in the Lithium Triangle.
Salar de Atacama/Arenas Blancas comprises 140 licenses covering 377 sq km in the Salar de Atacama basin, one of the leading lithium-producing regions in the world with proven mineable deposits of 9.2 Mt.
CleanTech Lithium is committed to an ESG-led approach to its strategy and supporting its downstream partners looking to secure a cleaner supply chain. In line with this, the company plans to use renewable energy and the eco-friendly DLE process across its projects. DLE is considered an efficient option for lithium brine extraction that makes the least environmental impact, with no use of evaporation ponds, no carbon-intensive processes and reduced levels of water consumption. In recognition, Chile’s government plans to prioritize DLE for all new lithium projects in the country.
CTL has a DLE Pilot Plant which is located in Copiapó with the capacity to produce up to 1 tonne per month of lithium carbonate. The company recently sent 24m3 batches of concentrated eluate to North America for further downstream processing. This will produce battery-grade lithium in the coming weeks and months. The company will share with potential customers across car and battery manufacturers.
