Tungsten Mineralisation Confirmed at Defender
Great Western Mining Corporation PLC has announced significant tungsten mineralisation at its Defender Tungsten Project in Nevada, with channel sampling revealing Channel A intercepted 6 meters at 0.17% WO3, including 1 meter at 0.43% WO3, and Channel B yielded 16 meters at 0.30% WO3, including 2 meters at 0.66% WO3. Additionally, Channel B showed silver mineralisation, with 2 meters at 2.95 g/t Ag and 3 meters at 1.55 g/t Ag, and importantly, potential penalty elements were found in very low concentrations, which is positive for processing.

[{"type":"text","content":"\n\n \nGreat Western Mining Corporation PLC / AIM: GWMO / Euronext Growth: 8GW\n \n29 January 2026\nGREAT WESTERN MINING CORPORATION PLC\n(\"Great Western\", \"GWM\" or the \"Company\")\n \nTungsten Mineralisation Confirmed at Defender\n \nGreat Western Mining Corporation PLC, a strategic minerals exploration and development company, is pleased to announce assay results from a machine-cut channel sampling programme at its Defender Tungsten Project (\"Defender\" or the \"Project\") in Mineral County, Nevada USA.\n \nHIGHLIGHTS\n· Two machine-cut channels completed in December 2025 at Defender returned significant tungsten mineralisation:\no Channel A intercepted 6 m (20ft) @ 0.17% WO3, including 1 m (3ft) @ 0.43% WO3 (Table 1).\no Channel B intercepted 16 m (52ft) @ 0.30% WO3, including 2 m (7ft) @ 0.66% WO3 (Table 1).\n· Very low concentrations of potential penalty elements encountered during WO3 processing (Table 1).\n· Silver (Ag) mineralisation found in Channel B, with 2 m (6.5ft) @ 2.95 g/t Ag in the garnet skarn and 3 m (10ft) @ 1.55 g/t Ag in granite.\n \nGreat Western Chairman Brian Hall commented: \"In a rapidly changing world in which tungsten has become a critical metal for defence and industrial use, currently in short supply in the West, the confirmation of significant mineralisation at Defender is a very exciting development for Great Western. This initial channel sampling operation has confirmed the presence of tungsten, which was previously indicated by soil and rock chip sampling last year, with results firmly at the upper end of our expectations. Notably, minerals that could impair processing such as molybdenum and lead were immaterial in the results. We are now planning the next stages and will keep shareholders informed.\"\n \nDETAILS\nBackground\nThe Defender and Pine Crow tungsten skarns, which produced tungsten during World War II, lie approximately 2 km northeast of and on trend with the Company's M2 skarn copper resource. All these skarns occur at the contact zones of Cretaceous granitic intrusions with limestones of the Jurassic Dunlap Formation. Field mapping and grab sampling reported in June 2025 confirmed scheelite-bearing skarns at both Defender and Pine Crow, with rock chip samples recording up to 1...
