Retail Offer to Shareholders

On 10 February 2024, CleanTech Lithium PLC ("CleanTech Lithium" or the "Company"), an exploration and development company advancing lithium projects in Chile for the clean energy transition, announced an accelerated bookbuild to raise gross proceeds of £2.4 million by way of a placing of 15,000,000 new Ordinary Shares (the "Placing Shares") at a price of 16 pence per new Ordinary Share (the "Issue Price") (the "Placing").

The Company has also granted a broker option to Fox-Davies Capital Limited ("Fox-Davies"), pursuant to which up to an additional £2.0 million can be raised at the Issue Price until 5.00 p.m. on 25 February 2025 (the "Broker Option") (the Placing and the Broker Option together being, the "Fundraising").

As part of the Fundraising, the Placing Shares will carry a warrant entitlement of one warrant ("Warrant") for every Placing Share. Each Warrant grants the holder the right to subscribe for one new Ordinary Share at a price of 11p, being approximately 31% per cent. below the Issue Price, at any time from one year after the date of admission of the Placing Shares to trading on AIM ("First Admission") until up to and including the date which is 4 years from the date of First Admission.

In view of the potential interest of retail shareholders in participating in the Fundraising, the Company is pleased to announce a retail offer via BookBuild (the "Retail Offer") of new ordinary shares (the "Retail Offer Shares") at a price of 16 pence per Retail Offer Share together with one Warrant for every Retail Offer Share. The Retail Offer is only being made available to existing shareholders of the Company on the same financial terms as shares are available under the Broker Option.

The Issue Price represents a discount of approximately 1.6 per cent. to the closing share price per Ordinary Share on 7 February 2025, being the last practicable date prior to the announcement of the Fundraising.

The amount raised under the Broker Option and the Retail Offer will not in aggregate exceed £2 million.

The Retail Offer is conditional on:

• the passing of relevant resolutions (the "Resolutions") to authorise the issue of the Retail Offer Shares and the Warrants at a general meeting of the Company to be held on or about 19 March 2025 (the "General Meeting").
• The Retail Offer Shares being admitted to trading on the AIM market operated by the London Stock Exchange ("Second Admission").

It is expected that Second Admission will take place on or about 20 March 2025.

The net proceeds from the Broker Option (if exercised) and the Retail Offer would be applied to repaying the Company's outstanding loan notes (as detailed in the Company's announcement of 1 July 2024).
