Share capital reorganisation & Notice of GM

Great Western (AIM - GWMO, Euronext Growth - 8GW) announces that it is proposing to implement a share capital reorganisation whereby (i) the ordinary share capital of the Company will be consolidated on the basis of 1 Consolidated Ordinary Share of €0.02 each for every 200 Existing Ordinary Shares of €0.0001 each followed by (ii) the sub-division of 1 Consolidated Ordinary Share of €0.02 each into 1 New Ordinary Share of €0.0001 each and 1 Deferred Share of €0.0199 each (the "Share Capital Reorganisation").

The Company has today posted a circular to shareholders in connection with the Share Capital Reorganisation which is available on its website at www.greatwesternmining.com (the "Circular"). The Circular contains a general update as well as information about the background to and reasons for the proposed the Share Capital Reorganisation, to explain why the Board considers the share capital reorganisation to be in the best interests of the Company and its Shareholders as a whole, and why the Directors recommend that you vote in favour of the resolutions to be proposed at a general meeting to be held at 1 Windmill Lane, Dublin 2, Ireland on 20 March 2025 at 2:30 p.m. (GMT).

Upon implementation of Share Capital Reorganisation, Shareholders on the register of members of the Company on the Record Date, which is expected to be 6 p.m. on 28 March 2025, will exchange every 200 Existing Ordinary Shares they hold for 1 New Ordinary Share and 1 Deferred Share. The proportion of the issued ordinary share capital of the Company held by each Shareholder following the Share Consolidation will, save for fractional entitlements and subject to the exercise of share options and warrants, be unchanged.

Application will be made for the New Ordinary Shares arising from the Share Consolidation and Sub-division to be admitted to trading on the Euronext Growth Market and AIM. It is expected that admission will become effective and that dealings in the New Ordinary Shares will commence at 8:00 a.m. on 31 March 2025.
