Environmental Permit Effective

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 that an environmental permit recently granted to the Company's 50% owned affiliate, Western Milling LLC, becomes effective today, 31st. July 2024.

This permit has been granted by NDEP (The Nevada Division of Environmental Protection) and is the final step in allowing gravity operations to commence at Western Milling's site in Sodaville, Nevada.

NDEP's primary objective in granting this permit is to ensure no contamination of the water table and Western Milling has taken great care to plan and construct the mill site so that it meets and exceeds the minimum requirements for this phase 1 gravity separation plant. The mill site, as constructed, has also been engineered to take account of a potentially more hazardous second phase which will involve chemical leaching, for which an application will shortly be filed in line with previously announced plans.

No testing of any kind has been allowed until the permit is in place. The site has been left open for inspection pending the permit becoming effective. During a final inspection of the site by NDEP, no significant issues were identified and all the required parameters were found to have been met. Hook up of the plant for initial operations can now commence and the system tested prior to first production.

Great Western and its partner will each be contributing feedstock to the mill and Great Western is now setting up bulk transportation arrangements.

Great Western Chairman Brian Hall commented: "Long delays in reaching this point have been mainly outside our control but we are very excited to have a green light to go ahead and operate the plant. There is still a lot to do and we and will report on the next stages."
