CEOL Update and CFO Position

CleanTech Lithium PLC (AIM: CTL, Frankfurt:T2N), an exploration and development company advancing sustainable lithium projects in Chile, shares an update on the CEOL process and CFO position.

CEOL Update

The Company had expected ratification of the CEOL to take place in Q2 2026, however, the administrative process with the Comptroller General's Office is taking longer than anticipated as it works through all the CEOL decrees put forward by the previous Government. CEO Ignacio Mehech has met with the new Government representatives on several occasions and is encouraged by their support for the Company's ambitions at Laguna Verde and looks forward to the signing of the CEOL later this year.

CFO Position

It was announced on 11 August 2025 that CFO and Director Gordon Stein would step down from the Board as a director but remain as CFO. The Board engaged Mr Stein under a consulting agreement in February 2026 to lead the process to select a strategic partner to fund the next stage of project development and also to progress the dual listing on the ASX and as these matters are ongoing, Mr Stein's consulting agreement has now been extended from 30 June 2026 to the end of September 2026 when it will be reviewed again.
