CleanTech Lithium PLC

 ("CleanTech Lithium" or the "Company")

ASX Listing and CEO Designate

26 February 2025 - CleanTech Lithium PLC (AIM: CTL), an exploration and development company advancing sustainable lithium projects in Chile, announces that it now expects the Australian Securities Exchange ("ASX") listing to launch in April and complete in May. While the ASX listing process is taking longer than initially expected, the Board and our advisers believe that waiting for a positive decision by the end of March on entering the streamlined direct negotiation process for the Special Lithium Operating Contract ("CEOL") for Laguna Verde and completing the Pre-Feasibility Study ("PFS") will significantly strengthen our investment case in the Australian market.

The Company also recognises that, under ASX listing rules, it will now have to include 2024 year-end audited financials ("2024 Financials") in the ASX-listing Prospectus before the Prospectus can be published. The 2024 Financials are well-advanced and expected to be released by the Company before the end of March 2025, some three months earlier than normally planned so that the Prospectus can be finalised shortly thereafter. The Prospectus will also include results of the PFS, which is progressing well and is anticipated to be finalised and published in April.

The Company has been informed by Tony Esplin, nominated as CEO designate in November 2024, that he has reconsidered his position and, for personal reasons, will not be taking up his intended appointment as CEO. Mr Esplin's appointment was conditional on the successful listing of the Company on the ASX which is now expected to complete in May. The Company´s Executive Chairman, Steve Kesler, will continue as interim CEO whilst the Board re-engages with alternative candidates as the CEO to lead CleanTech Lithium into its next phase of growth.

Steve Kesler, Executive Chairman, CleanTech Lithium PLC commented:

"We believe that pushing out the ASX listing to include the resolution allowing the Company to enter direct negotiation with Government on the CEOL and results from the PFS will be taken positively by Australian investors. We regret that Tony has decided to withdraw from the proposed appointment as CEO, and we will start to re-engage with other high calibre candidates immediately."

The Board believes the ASX listing will enhance shareholder value and will provide further updates on the ASX listing and CEO search in due course.
