Notice of General Meeting and Posting of Circular

4 March 2025 - CleanTech Lithium (AIM: CTL), an innovative sustainable lithium developer in Chile, is pleased to announce that it is today posting a circular to Shareholders, including a notice of general meeting (the "Circular"). The general meeting will be held at the offices of the Company at de Carteret House, 7 Castle Street, St Helier JE2 3BT on 24 March 2025 at 11:00AM GMT (the "General Meeting"). 

On 11 February 2025 the Company announced that it raised £2.4 million (before expenses) by way of a placing of 15,000,000 new ordinary shares (the "Placing") at a price of 16 pence per share (the "Issue Price").

In addition to the Placing, the Company also announced that it had granted an option to Fox-Davies Capital Limited (the "Broker Option") and subsequently launched a retail offer via BookBuild to existing Shareholders of the Company (the "Retail Offer") pursuant to which in aggregate up to a further £2 million could be raised by the Company by the issue of ordinary shares ("New Ordinary Shares") at the Issue Price.

At the General Meeting, the Board is seeking Shareholder approval to:

· authorise the Directors to allot shares in relation to the Broker Option, the Retail Offer, the attached warrants and the warrants granted to Fox-Davies Capital Limited on a non-pre-emptive basis;

· renew the Company's existing general share authorities;

· permit the use of purely electronic communications with Shareholders; and

· adopt amended articles of association.

The detailed reasons for and background to the resolutions are set out in the Circular. The Circular will shortly be available on the Company's website https://ctlithium.com/investors/circulars-documents/. A letter notifying Shareholders of the availability of the Circular on the Company's website will be dispatched to Shareholders later today.

Proposed amendments to the Articles

The Company is proposing to adopt an amended set of articles of association, so as to allow shareholder communications via electronic means, such as email, website postings, or RNS, rather than by post. Shareholders will be notified that unless they actively request postal delivery, they will receive documents electronically by default. The proposed amendments also include a reduction to the deemed notice periods where notices are given by hard copy mail. These changes aim to improve efficiency, reduce costs, be more environmentally friendly, and speed up formal communications. The resolutions include adopting the revised articles of association and authorising electronic-only communication in compliance with AIM Rules. Further details are available in the notice of General Meeting.
