Result of Oversubscribed WRAP Retail Offer

East Star Resources Plc (LSE:EST), which is exploring for copper and gold in Kazakhstan, is pleased to announce the result of an oversubscribed WRAP Retail Offer. Due to the significant level of demand, the Company is increasing the amount it will accept from the WRAP Retail Offer to £340,992 and has therefore raised aggregate gross proceeds from the Subscription (which has also been increased) and WRAP Retail Offer of £622,292 (together, the "Fundraise"). Accordingly, the Company will issue a total of 47,868,616 new Ordinary shares at the Issue Price pursuant to the Fundraise.

Director Participation

Alexander Walker and Alexander ("Sandy") Barblett, who are Directors of the Company, have both participated in the Subscription, subscribing in aggregate for 1,846,154 new Ordinary shares (the "Directors' Subscription"). In the case of the Director's Subscription, the remaining Directors are deemed to be independent and consider the Director's Subscription to be fair and reasonable insofar as the Company's shareholders are concerned. Following Admission (as defined below), Mr Walker and Mr Barblett will own 12.87% and 0.77% respectively of the Company's enlarged issued share capital. Further information regarding each Director's participation in the Director's Subscription follows in the Appendix below.

Admission and Total Voting Rights

Application has been made for the new Ordinary shares to be issued pursuant to the Fundraise to be admitted to trading on the Main Market of the London Stock Exchange and to listing to the equity shares (transition) category of the FCA's Official List ("Admission"). Admission is expected to become effective at 8 a.m. on or around 13 June 2025.

Upon Admission, the Company's issued Ordinary share capital will consist of 445,384,535 Ordinary Shares with one voting right each. The Company does not hold any Ordinary Shares in treasury. Therefore, from Admission the total number of Ordinary Shares and voting rights in the Company will be 445,384,535. With effect from Admission, this figure may be used by Shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

The new Ordinary Shares to be issued pursuant to the Fundraise will be issued free of all liens, charges and encumbrances and will, on Admission, rank pari passu in all respects with the Company's existing Ordinary shares.

Terms used but not defined in this announcement have the same meaning as set out in the Company's announcement released on 5 June 2025. This announcement should be read in its entirety. In particular, the information in the "Important Notices" section of the announcement below should be read and understood.
