START OF 2022 DRILLING CAMPAIGN

Great Western Mining Corporation PLC (AIM - GWMO, Euronext Growth - 8GW), which is exploring and developing gold, silver and copper targets in Nevada, is pleased to announce the commencement of its 2022 drilling campaign.

The Company has contracted a reverse circulation (RC) rig for a drill programme of approximately 11,000 ft (3,350 m), which has now commenced at the Southern Alteration Zone (SAZ) in the Rock House group of prospects.  Three initial holes are planned at the SAZ to follow up on the encouraging results from the 2021 programme, where the best intercepts were (1) 1.52 metres at 8.02 g/t gold from 97.53 metres downhole in hole RHRC006 and (2) 1.52 metres at 2.29 g/t gold from 28.95 metres downhole in hole RHRC007.  Drilling is targeting the continuation of veins already identified.

Great Western Chairman Brian Hall commented:  "We have a busy drilling season now under way on several of our prospects and will keep shareholders informed as we make progress."

Notes to Editors

The Company has a large acreage position in Mineral County, Nevada. The area consists of rugged, mountainous terrain, which means that large parts of it 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. 

Six of the Company's properties are in the west of Mineral County and are 100% owned and operated.  The Company has an option to acquire a seventh property, the Olympic Gold Project, in the east of the county.  Great Western's small exploration team is supported by locally based consultants and contractors. 

The state of Nevada is generally considered to be one of the world's most mining friendly jurisdictions.  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. 

Furthermore, through extensive drilling over a five-year period, GWM has established a Mineral Resource on its first target area known as M2, of 4.3 million tonnes at 0.45% copper, for 19,000 tonnes of contained copper metal. This resource has been independently reported in accordance with JORC guidelines.
