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

COPPER AGREEMENT AT EASTSIDE MINE

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 it has entered into a pooling agreement (the "Agreement") with Bronco Creek Exploration, Inc. ("Bronco Creek") for developing copper potential in and around the Company's Eastside Mine group of claims in Mineral County, Nevada.

The Eastside Mine group is located approximately 11 miles to the southeast of Great Western's current focus of copper exploration activity in the Huntoon Valley region. Bronco Creek's 'Tango Project' adjoins Great Western's holdings at Eastside Mine (together the "Pooled Project").  The Agreement pools the respective projects for the purpose of consolidating a primary porphyry target.  Bronco Creek will serve as the operator of the Pooled Project, with the intention of advancing the target concept and with the ultimate goal of including the Pooled Project in an exploration and option agreement with a future partner to fund exploration and development.    

Benefits and liabilities will be shared by the parties to the Agreement 30% Great Western / 70% Bronco Creek, being approximately the ratio of the claims held by each party.    No formal joint venture is created by the Agreement and each party will continue to own its own claims. 

In addition to the copper bearing prospects, Great Western and Bronco Creek have identified intense quartz-sericite-pyrite "QSP" alteration, which is indicative of the high levels of a porphyry copper system over a significant area of the Pooled claims.  Furthermore, the targeted porphyry system appears to extend beneath post-mineral cover, adding additional exploration upside to the Pooled Project.

Bronco Creek is a division of EMX Royalty Corporation which has a large and active portfolio of mining operations and investments, in north America and around the world.

Great Western Executive Chairman Brian Hall commented: "We are very pleased to be working with Bronco Creek on this project.  We have long considered Eastside Mine to be a valuable asset and in recent times have conducted an IP survey over the area, resulting in the identification of drill targets.  By pooling acreage into a much bigger unit and working with a larger and well-resourced company, we are implementing our strategy of attracting funding at the project level without recourse to shareholders.

"Within one year we have now therefore identified two potential porphyry deposits on our claims.  At the Huntoon copper project we are working to establish connectivity of copper showings across the Huntoon Valley.  Eastside Mine is some distance away from the Huntoon Valley, where field work is ongoing, and a completely separate but equally interesting porphyry prospect."

Notes to Editors

The Company has a large tract of acreage 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, copper and other minerals 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 the seventh and most recent acquisition, the Olympic Gold Project, is in the east of the county, some 50 miles from the main group.  All are 100% owned and operated.  Great Western's small exploration team is supported by locally based consultants and contractors. 

The state of Nevada is 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. The Company is party to a 50-50 joint venture known as Western Milling LLC which is constructing a mill to process pre-mined material for secondary recovery of gold and silver.

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. 

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.  Additionally, exploration targets 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.
