Operational Update

Great Western Mining (AIM: GWMO), the copper gold and silver exploration company with targets in Mineral County, Nevada, announces that its 2018 drilling programme has now commenced.

The Company's operating team is already at its base in Marietta and the O'Keefe Drilling team is on site. The initial programme has been designed to minimise use of water in the early stages, as the supply of water at this time of year is restricted by extremely low temperatures which can fall to -18˚ Celsius.

The Company will initially commence infill drilling at the logistically simpler M2 target and, upon completion, move to M4 (Target 4) where approximately 60% of the drilling programme has already been completed as part of last year's programme.

Additionally, Sharktooth drilling is expected to commence in the first quarter of this year, for which Great Western Mining has already contracted an additional diamond core drilling rig.

By bringing forward the programme and prioritising M2 during the winter months, the Company should be in a position to report the results of M2 ahead of the M4 (Target 4) results.

Chief Executive, David Fraser commented: "We are making good progress with the 2017/18 drill programme, despite a difficult operating environment in the Huntoon Valley, and are confident that our efforts will bear fruit. We will continue to keep shareholders updated."
