Update to Legal Claim in Chile

CleanTech Lithium (AIM: CTL, Frankfurt: T2N), an exploration and development company advancing sustainable lithium projects in Chile, provides an update in relation to a legal claim involving its wholly owned subsidiary CleanTech Laguna Verde SpA ("CLV").

As previously reported on 1 December 2025, a civil legal claim was lodged by the vendors of 23 mining concessions at Laguna Verde (the "LV Vendors") against CLV in relation to the non-payment of the second instalment as part of the sales and purchase agreement, details of which were announced on 22 April 2024. While there has been no further developments of that civil claim, the Company understands that a related criminal complaint has now been filed by the LV Vendors to a local court in the Atacama Region against CLV, CleanTech Lithium Ltd and Atacama Salt Lakes SPA, both subsidiaries of the Company, and certain Directors and Officers of the group, covering substantially the same matters.

These allegations are denied by the parties concerned and the Company views these in the context of the previously announced contractual dispute. The Company does not believe that this new legal action has any impact on its operations and strategic plans but will provide further updates to the market as appropriate.
