Exploration Update

Great Western Mining Corporation PLC, a strategic and precious metals exploration and development company, is pleased to provide an update on exploration activities at key targets in the Walker Lane belt of Nevada, USA.

• 1,800-metre reverse circulation (RC) drilling programme at the high-priority Rhyolite Dome and West Huntoon prospects is on schedule and is now expected to commence during the week beginning 6 October.
• All permits are in place with authorisation to drill at the Rhyolite Dome gold prospect received, ensuring the programme can proceed without delay.
• Recently completed IP survey at Rhyolite Dome is being used to pin-point drill locations.
• Acquisition of cuttings from three RC holes drilled at West Huntoon by a previous operator but never processed will be analysed and provide valuable additional data.
• Great Western's dedicated operational and technical team is now in place to oversee the campaign and maximise efficiency and data quality.
• Assay results from soil sampling programme at high-grade Pine Crow/Defender Tungsten prospects expected from the laboratory shortly.

Great Western Chairman Brian Hall commented: "We are eager to start our fully funded drill programme, both at Rhyolite Dome which has never previously been drilled and to build on previous work at West Huntoon, where a strategic drill hole intersected 45.7m at 0.27% copper and where there is also potential for precious metals. These two targets represent significant gold and copper opportunities within a region of world-class geology and our exploration activities to date have delivered consistently encouraging results. Our aim with this drilling programme is to generate robust results that de-risk and validate the work done to date, with every metre drilled contributing to an enhanced picture of the subsurface and the resource potential of our portfolio. We look forward to providing further news flow throughout Q4, reporting on progress as this drilling programme advances and on results from our soil sampling programme at the high-grade Pine Crow/Defender Tungsten prospects."
