Huntoon Mine Area Cooperation Agreement

Great Western Mining Corporation PLC (AIM - GWMO, Euronext Growth - 8GW), which is exploring and developing gold, silver and copper targets in Nevada, announces the signing of a new agreement with Crowne Point Gold & Silver LLC ("Crowne Point") for cooperation in exploring the western part of the Huntoon Valley (the "Agreement").

The Agreement novates a previous cooperation agreement with Crowne Point, signed in 2016 but now expired, under which a single hole, CPGW_1, was drilled, intercepting both copper and gold. The Agreement has been negotiated primarily to build on Great Western's recent progress in establishing the copper potential of its West Huntoon claims.

HIGHLIGHTS

• Early drilling on private land will attempt to prove up a copper porphyry
• Access to existing infrastructure
• Potential for both copper and precious metals
• Great Western to focus on copper potential, Crowne Point on precious metals

Great Western has recently staked and registered an additional 19 claims in the West Huntoon Valley and now holds 126 full and 12 fractional claims which form part of the Company's larger Huntoon Copper Project area, where a copper resource has already been reported at M2. Crowne Point owns patented land equivalent in area to six standard claims (the "Six Claims") and which is surrounded by Great Western claims. The Six Claims include the historic and abandoned Huntoon gold mine, together with a comprehensive network of access roads. Under the Agreement, Great Western will have access to the Six Claims and in return will assign a 50% interest in nine of its unpatented claims to Crowne Point. The surface rights on the Six Claims belong to Crowne Point and the Agreement will enable Great Western to drill on and from them without the requirement to obtain regulatory approval which could otherwise cause long delays. Initial drilling will be aimed at proving up the copper porphyry potential of the West Huntoon area which Great Western identified during its productive 2023 field programme, as already announced to shareholders.

Each party will plan its own exploration activity and bear its own exploration cost unless a decision is made to explore on a joint basis. The Agreement includes the following provisions:

• Copper or other base metal discovered by Great Western on the Six Claims will be owned in equal shares and gold or precious metals discovered by Crowne Point will be shared 70% by Crowne Point and 30% by Great Western.
• Any minerals discovered by Great Western on its own claims through angled drilling from the Six Claims will belong exclusively to Great Western except where the drilling targets shared claims, in which case the benefits of any discovery may be shared equally between the parties subject to Crowne retroactively reimbursing Great Western for 50% of the direct costs of drilling the discovery.
• Any value extracted from pre-existing mining waste present on Crowne Point's existing claims will belong exclusively to Crowne.

Great Western Chairman Brian Hall commented: "We have successfully cooperated with Crowne Pointe in the past and are very pleased to have entered into this new cooperation arrangement with them. The flexibility to carry out initial drilling on private land, which will circumvent a potentially lengthy permitting process, will enable us to fast-track our work in defining what we consider may be a significant new copper porphyry in the Walker Lane trend of Nevada. We are actively seeking a joint venture partner to help finance this programme and currently working on several positive leads."
