East Star Resources Plc

("East Star" or the "Company")

Issue of Performance Shares to CEO

East Star Resources Plc (LSE:EST), the Kazakhstan focused copper exploration and resource development company, announces the issuance of 31,874,202 ordinary shares of 1 pence each ("Ordinary Shares") to Alex Walker, Chief Executive Officer of the Company (the "AW Performance Shares") pursuant to the achievement of the Mineral Resource Estimate performance threshold announced on 8 July 2024. The AW Performance Shares are expected to be admitted to trading on or around 16 July 2024.

At this time, only the 31,874,202 Performance Shares due to Mr Walker, being a director and employee of the Company are to be issued.

The balance of 43,125,798 Performance Shares also due to be issued to the DVK Vendors (as defined in the 8 July 2024 announcement) will now only be issued at such time in the future when the Company has all necessary approvals to admit them to trading, which, inter-alia, is likely to require the publication of an approved Prospectus.

Sandy Barblett, East Star Chairman, commented:

"Alex Walker and the team have done a tremendous job in establishing a large copper JORC Inferred Mineral Resource at Verkhuba which is now the subject of third-party interest. We are pleased that this performance milestone has been achieved and believe it is just the first of a number of future successes to come from the Company's copper strategy. As outlined above, the balance of the Performance Shares will be issued to the remaining DVK Vendors - a highly supportive, long-term group of investors - in due course."

Following the allotment and admission of the 31,874,202 Performance Shares, Mr Walker, holds a total of 53,153,403 Ordinary Shares representing 21.12 percent of the enlarged share capital.

Admission of Shares and Total Voting Rights and Warrants

An application has been made for the AW Performance Shares, which will rank pari passu with the existing ordinary shares in issue, to be admitted to trading on the Official List of the UK Listing Authority and to trading on the Main Market of London Stock Exchange plc ("Admission"). It is anticipated that Admission will become effective and that dealings in the ordinary shares will commence at 8.00 a.m. on or around 16 July 2024.

Following Admission, the Company will have 251,724,699 ordinary shares in issue. The Company does not hold shares in treasury, therefore the figure of 251,724,699 should be used by shareholders for the calculations by which they will determine if they are required to notify their interest in, or a change of their interest in, the share capital of the Company under the FCA's Disclosure and Transparency Rules.
