CLEANTECH LITHIUM PLC - Investor Update

CleanTech Lithium PLC provided an investor update highlighting progress towards developing its flagship Laguna Verde lithium project in Chile, with management describing the company as approaching a key transition from exploration to development. The company remains confident that its Special Lithium Operating Contract (CEOL) will be ratified during 2026, supported by ongoing engagement with Chile’s Mining Ministry, while environmental baseline work is expected to begin before 21 December ahead of a targeted EIA submission in Q3 2027. CleanTech Lithium is also progressing its proposed ASX dual listing, expected during 2026, alongside discussions with potential strategic partners across Asia, Europe and the US, with a partner targeted to help fund the DFS, environmental studies, additional exploration and reinjection pilot testing through to FID. Operationally, the company has produced 330kg of high-purity lithium carbonate from Laguna Verde brine, achieving purity of 99.6%–99.9%, while further DLE optimisation, adsorbent testing and spent-brine reinjection studies are underway. Management also highlighted an amended Laguna Verde vendor settlement that reduced the agreement cost by 60% and aligned future payments with project milestones, with the company now controlling 99% of licences within the CEOL area. With the CEOL ratification, strategic partner process, ASX listing and environmental permitting advancing concurrently, CleanTech Lithium believes it is approaching a significant inflection point in its growth strategy and the development of Laguna Verde.
