Placing and Retail Offer

Great Western Mining Corporation PLC (AIM - GWMO, Euronext Growth - 8GW), which is exploring and developing gold, silver and copper targets in the Walker Lane belt of Nevada, USA, announces a placing to raise gross proceeds before expenses of £300,000 through the issue of 1,818,181,818 New Ordinary Shares of €0.0001 each (the "Placing Shares") at a price of 0.0165 pence each (the "Placing"). CMC Markets UK PLC, trading as CMC CapX, acted as the Company's placing agent in respect of the Placing.

In addition to the Placing, the Company also intends to offer its existing shareholders a "Retail Offer" of new Ordinary Shares at the same Issue Price as the Placing (the "Retail Offer Shares" and together with the Placing Shares the "Fundraising Shares").

The Company will release a separate announcement regarding the Retail Offer and its terms. For avoidance of doubt, the Placing is separate from and is not conditional on the Retail Offer.

USE OF PROCEEDS

Great Western will use the proceeds from the Fundraising Shares for some or all of the following:

• Complete commissioning of process mill for pilot production
• Create optimum drill programme for West Huntoon copper porphyry
• Analyse and report on 751 soil and grab samples taken over six prospects during 2024 field season (TUN, W Huntoon, M2 NE extension, M5 NE extension, Smith Mine and Rock House)
• Pursue tungsten opportunities in the Black Mountain claims group in the vicinity of two historic mines
• General corporate purposes

Great Western Chairman Brian Hall commented: "We have a busy programme of exploration and development and are making good progress on all fronts. The West Huntoon copper porphyry project is now effectively drill ready and we are anticipating pilot production of gold and silver concentrates at the Western Milling joint venture in the near future. We are also looking at other promising mineral opportunities on and around our claims. This Placing will enable us to continue our efforts effectively and we are taking the opportunity to make new shares available to existing shareholders through a Retail Offer which will shortly be announced".
