Operational Update

Great Western Mining (AIM: GWMO) provides the following update on operations in Mineral County, Nevada, USA.

The M2 infill drilling programme has been proceeding well despite some technical and operational difficulties which has resulted in a slight delay in the completion of the eighth hole of the programme M2-040. These issues have now been resolved and the hole is expected to be completed by the end of the week. Assay samples from the earlier holes are currently being processed by Bureau Veritas in Reno, with the Company expecting to start receiving results around the end of next week.

The GWM field team has been able to bring forward the scheduled start of the permitted three-hole M2 Sharktooth Zone diamond core drill programme and drilling on the first borehole M2-041 commenced 17 April. The programme plans for these holes to reach depths of between 775 and 900 metres. As of 22 April, M2-041 had reached a depth of 122 metres.

Great Western Mining also announces that final approval has now been received from the United States Forestry Service ("USFS") for the re-commencement of M4 (Target 4) drilling. The M4 diamond core drill rig, crew and support equipment are now all on site and drilling is expected to commence later this week.

Upon completion of M2-040, GWM has agreed with joint venture partner Crown Point Gold & Silver LLC to move the Reverse Circulation drill rig, currently on the M2 infill programme, to M1. GWM plans to drill a bore hole on the south-east border of the property shared with Crown Point to test for further copper mineralisation, as announced in the M1 November 2017 update.

Chief Executive, David Fraser commented: "The 2018 drill programme is now starting to move through the gears as weather conditions in the Huntoon Valley improve. For the first time we will be drilling with three rigs simultaneously and we are relishing the task of accelerating operations. We expect to receive the first results from the M2 infill drill programme in the next couple of weeks and will update shareholders on these and future developments."
