M2 and M4 Operational Update

Great Western Mining (AIM: GWMO), the copper, gold and silver exploration company with targets in Nevada, is pleased to provide the following update on the Company's M2 and M4 (Target 4) Copper-gold prospects.

Contracts have now been agreed with O'Keefe Drilling Company for this autumn's drill programmes on M2 and M4. The drill rig is currently being mobilised to site with drilling set to commence mid-October, and expected to continue until the end of this year.

The M2 programme is targeting a resource extension and increase of the quantity of resource classified in the JORC Indicated category. The current JORC compliant resource estimate is 16,989,570 tonnes of 0.52% copper, with 3,914,740 Indicated and 13,074,830 Inferred. Up to 7 drill holes are planned for a total of 800 metres.

The M4 programme is a discovery level programme of 6-9 drill holes totalling 950 metres. The aim is to test the thickness of the identified surface copper oxide mineralisation, and to intercept the IP anomalies indicated by GWM's Resistivity Report conducted by Zonge Geosciences.

The GWM field team is currently on site preparing access roads, flagging out the over land routes, supervising bulldozing and preparation of equipment and documentation. In addition, the field team is planning further detailed geological lithological and alteration sections to help refine the Sharktooth Exploration Target drill hole locations, in preparation for a Sharktooth discovery level drill programme planned for early 2018.

Great Western Mining CEO, David Fraser commented: "We are excited by the potential to further enhance the JORC status of the M2 prospect. The drilling is also set to provide further insight into the mineralisation at M2 and M4, which we believe could prove to be continuous, highlighting the significant potential of the area. The Company has also allocated funds to a discovery level drill programme on our Sharktooth Exploration Target, which we will look to commence as soon as the weather permits in early 2018. These are exciting times for Great Western Mining, and we look forward to updating shareholders as we make progress with our objective of establishing Marietta as a major copper district."
