GREAT WESTERN MINING CORPORATION PLC

("Great Western", "GWM" or the "Company")

OTCID Application Submitted

Great Western, the exploration and development company focused on mineral projects in the state of Nevada, USA, is pleased to announce that it has submitted an application to the OTC Markets Group for its ordinary shares to be cross-traded on the OTCID market in the United States, as part of its strategy to broaden its investor base and enhance visibility in the North American capital markets.  

The board of Great Western believes that a cross-trading of Great Western's ordinary shares on the OTCID would provide significant benefits to investors, including enhanced access to trading for US-based investors and greater liquidity from a broader pool of potential investors globally. By trading on the OTCID, Great Western will engage directly with US investors, providing them with the same level of information and disclosure available to shareholders in the United Kingdom, but through US-facing platforms and portals. Additionally, the OTCID cross-trading facility will enable US investors to access Great Western's ordinary shares in US dollars, during US market hours.

The OTCID Market is recognised as an established public market for developing companies and does not require issuers to meet additional financial reporting and compliance standards. It is expected that approval and admission to trading will take up to six weeks and a further announcement will be made in due course. The Company's ordinary shares will continue to trade on AIM and Euronext Growth.

Great Western Chairman Brian Hall commented: "Subject to the necessary approval and admission process, trading on OTCID will open Great Western to a new and diverse pool of potential investors in the US who are seeking exposure to metal development, including strategic metals such as tungsten. Our assets are located in a Tier 1 jurisdiction in the US, and I believe it to be a natural next step for us to enable North American investors to trade, and benefit from, assets within their own country.

"Trading on the OTCID is an important component of this vision, offering investors a significant and domestically sourced pathway to gain exposure to this high-growth and strategically important commodities."
