GREAT WESTERN MINING CORPORATION PLC

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

PERMIT FOR MILL OPERATIONS

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, is pleased to announce that on 16 July 2024, late in the day Pacific Time, the Nevada Division of Environmental Protection ('NDEP') issued a Notice of Decision with regard to Western Milling LLC's proposed operations in Nevada.  Western Milling LLC, which is 50% owned by Great Western, has constructed a mill for processing precious metal concentrates from mining waste at Sodaville, adjoining the small town of Mina, Nevada.

NDEP has decided to issue a new Water Pollution Control Permit to Western Milling LLC authorising the construction, operation and closure of approved mining facilities.  The Permit will become effective on 31 July 2024 subject to any appeals which must be filed by 26 July 2024.   Western Milling is authorised to process up to 18,000 tons of ore per year.  No objections to the permit were lodged during the 30-day consultation period which ended on 10 July.

As soon as the permit is effective, Western Milling LLC will commission the mill to enable gravity processing operations to commence.

Great Western Chairman Brian Hall commented:  "With no objections filed, we will shortly be in a position to begin the commissioning process.  I would like to thank shareholders for their patience and our partners and our own personnel for their perseverance. We very much look forward to commencing operations on site and will provide further updates as we move towards production."

Notes to Editors

The Company has a large tract of acreage in Mineral County, Nevada. The acreage partly consists of rugged, mountainous terrain, large parts of which remain under-explored. Mineral potential is hosted by the regional Walker Lane Structural Belt, the largest structural and metallogenic belt in Nevada, yet one of the least explored in recent times, with gold, silver and copper currently produced in Mineral County.  Great Western has seven distinct concession areas which offer the potential for exploiting (1) short term gold and silver deposits and (2) long-term, world-class copper deposits. 

The Company's properties are made of seven groups of claims, all in Mineral County, Nevada and are 100% owned and operated. Great Western's small exploration team is supported by consultants and locally based contractors. 

The state of Nevada was rated the world's most mining friendly jurisdiction by the Fraser Institute of Canada in 2023.  While tightly regulated and environmentally conscious, Nevada welcomes the mining industry.  Great Western takes care to ensure that its claims are maintained in good standing and all regulations observed. 

There are numerous gold and silver prospects on the Company's acreage, including extensive historic mine workings which offer the opportunity for secondary recovery. As well as mineral exploration and appraisal, the Company is a 50% participant in the Western Milling LLC joint venture which has now completed construction of a mill to process pre-mined material for secondary recovery of gold and silver. 

Through extensive drilling over a five-year period, GWM has established a Mineral Resource on its M2 target area in the Black Mountains group of claims.  4.3 million tonnes at 0.45% copper are reported, being 19,000 tonnes of contained copper metal. This resource has been independently reported in accordance with JORC guidelines. 

GWM has also established an Inferred Resource Estimate of 31,000 tonnes grading 1.6 g/t gold and 3.0 g/t silver in tailings associated with the OMCO Mine at the Olympic Gold Project.   Waste material also  includes exploration targets which have been independently reported as follows:

3,400 - 6,400 tonnes grading between 0.5 and 1.2 g/t Au and 1.2 and 2.1 g/t Ag in the substrate beneath the tailings volume at the Olympic Mine.

·    9,000 - 12,000 tonnes grading between 0.9 and 2.4 g/t Au and 2.0 and 5.1 g/t Ag in a coarse stockpile at Olympic Mine.

·    4,200 - 7,700 tonnes grading between 40 and 140 g/t Ag and 0.3 and 0.3 g/t Au in spoil heaps at Mineral Jackpot.
