CleanTech Lithium PLC ("CleanTech Lithium", "CTL" or the "Company")

Update to Laguna Verde Licence Payment Terms

CleanTech Lithium PLC (AIM: CTL, Frankfurt:T2N, OTCQX:CTLHF), an exploration and development company advancing sustainable lithium projects in Chile, announces that the Company has reached an agreement with the Laguna Verde Option Vendors ("Vendors") to extend the due date of the second staged payment of US$1.25 million (the "Payment"), scheduled for Monday 21^st October 2024, under the sales and purchase agreement ("SPA") which was announced on 22^nd April 2024 (the "Announcement"). The agreed extension for the Payment accommodates the additional time the Company needs to complete the listing process on the Australian Securities Exchange ("ASX"). It is expected that the Payment will now be made following the completion of the ASX listing, intended for later this year.

The Company is pleased to remind shareholders of the significant progress at the Laguna Verde project since the Announcement, which detailed the acquisition of the 23 remaining licences (the "Licences"), previously subject to an option agreement, and the associated staged payments for the Company to have full ownership of the Licences. As previously communicated, CTL made the first payment under the SPA at the time of execution.

CleanTech Lithium confirms that the extension to the Payment will not affect CTL's holding of the Laguna Verde Option Licences. The Company retains 100% ownership of the Licences which will form part of the Special Lithium Operating Contract ("CEOL") application the Company plans to submit to the Chilean Government before the end of this year.

CTL is making good progress with its advisers on its planned ASX listing and will provide a further update on the timing in due course.

Steve Kesler, Executive Chairman and Interim Chief Executive Officer, CleanTech Lithium PLC, said:

"I am grateful for the Vendors understanding and agreement to extend the payment deadline in light of the ASX listing delays. This collaborative approach underscores the strength of our partnership and reinforces our commitment to mutual success. As we work through this phase, we remain highly optimistic about the long-term outlook for the lithium market. The demand for lithium will continue to rise, driven by the needs of electric vehicles and energy storage solutions. We believe we are well positioned in Chile to become the next lithium producer to help meet this demand."
