COMPLETION OF DRILLING AT OLYMPIC GOLD PROJECT

MINERAL JACKPOT DRILLING PERMIT

Great Western Mining Corporation PLC (AIM - GWMO, Euronext Growth - 8GW) advises that it has now completed its planned, first-phase drilling programme for gold and silver at the Olympic Gold Project in Mineral County, Nevada. 

Eleven holes across four target areas have been satisfactorily completed, of which six were at the Trafalgar Hill prospect (OMRC-1 to 6) where gold has been mined in the past, one at the West Ridge prospect (OMRC-7) and a third (OMRC-8) to the south of the former OMCO Mine which produced gold at high grades until the 1940s as previously reported.

The remaining three holes (OMRC-9 to 11) have now been drilled to the east of a fault which was the previously known limit of the most significant productive vein at the Olympic Mine. The holes were planned to target anomalies identified by a magnetometer survey conducted by the Company in 2020.  

Drill cuttings from the reverse circulation rig are currently being analysed at an independent laboratory in Nevada to assess the gold and silver content of each of the drill holes. Results for each target area will be announced once they have been analysed in-house.

Depending on the results, the Company plans infill drilling on some or all of these prospects later in the summer, subject to permitting. Meanwhile the Reverse Circulation rig is being moved to the RH (Rock House) Group for the next phase of the 2021 drilling campaign.

Elsewhere, at the Mineral Jackpot Group Great Western has now received a permit from the Bureau of Land Management to enable test drilling of known veins which have been mined in the past.  

Great Western Executive Chairman Brian Hall commented: "Drilling operations at Olympic Gold have been completed ahead of schedule, within budget, and we now await the assay results as the rig is moved to the previously undrilled RH Group, which has exciting potential for the Company. At Mineral Jackpot, where plans are going ahead for commercial recovery of gold and silver from previously mined spoil heaps, the drilling permit will enable us to progress our assessment of the potential for further gold and silver recovery in this area of historic mining."
