Mill Update

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, provides the following progress update on its 50% owned Western Milling project in Nevada for production of precious metals and concentrates from mining waste.

• All equipment on site for pilot production by gravity separation
• Pilot production will process initial batches of tailings brought from the OMCO mine site at the Olympic Gold Project
• When production has been established, a rod mill for crushing larger grades will be moved into place, initially from a stockpile of mined ore at OMCO, and this will be crushed and processed through the system
• First production in early December is anticipated by the operating partner
• The mill site has been constructed on a scale which will allow for planned chemical leaching in a second phase
• A walk-through introduction to the mill site together with recent drone footage is available on the Company's website

Great Western Chairman Brian Hall commented: "Western Milling is in the final stages of bringing its mill on to pilot production. Essential work is being finalised, primarily to ensure that operations meet the requirements of stringent health and safety regulations for a mining operation, at both state and federal levels. Great Western is supplying tailings from the OMCO Mine for first production from the plant together with initial batches from its stockpile of mined ore. Shareholders will be well aware that this project has taken much longer to reach this stage than we initially expected but we are confident that ownership of a local mill will provide a significant opportunity for the Company to process historic waste material as well as newly mined ore. Following a recent site visit, we expect production start-up in early December.
