OPERATIONS UPDATE

16 April 2021

Great Western Mining Corporation PLC (AIM - GWMO, Euronext Growth - 8GW) is pleased to announce that drilling has now commenced at the Olympic Gold Project ("Olympic") in Mineral County Nevada.

All necessary permits have been received and a Reverse Circulation ("RC") rig has been mobilised to the Trafalgar Hill prospect which lies in the northwestern part of the Olympic claims. Ground has been broken on the first of six planned holes to be drilled at Trafalgar Hill, where prospects have been identified through geological mapping and two recently-conducted magnetometer surveys. Drilling is currently in progress.

Following the completion of the Trafalgar Hill programme, the rig will remain at Olympic but move to the West Ridge prospect and then to the East OMCO Fault prospect, to the southeast of the historic OMCO Mine. Three further holes are planned to test magnetic anomalies to the east of the current Olympic group of claims for which the company has staked 12 new claims and submitted application to the Bureau of Land Management. In total, 11 holes are planned at Olympic prior to the rig moving to drill at the Company's Rock House ("RH") Group of claims.

This is the first time that the Company has drilled at Olympic, over which it acquired a 4-year purchase option in 2020.

The Company will provide further updates when new information becomes available.
