Great Western Mining Corporation PLC (LON:GWMO), a strategic and precious metals exploration and development company, has announced an update on its 100% owned and highly prospective Pine Crow-Defender tungsten prospect in Mineral County, Nevada.
Further to the Company’s 18 November 2025 announcement, in December the GWM exploration team completed a machine-cut channel sampling programme over existing trenches at the Pine Crow-Defender prospect. This work followed anomalous soil sampling results reported in October and the Company considers that these trench samples have strong potential to confirm zones of broad and consistent tungsten mineralisation.
Initial observations from the trenching programme are highly encouraging and the samples have been dispatched to a laboratory for assay. The results are expected during January and could be used in the design of an early drill programme.
Development of a tungsten asset is aligned with US demand for secure domestic supplies of critical and strategic minerals.
Commenting on the year, Brian Hall, Executive Chairman of Great Western Mining, said:
“2025 was a year of solid exploration progress for Great Western, involving copper, precious metals and tungsten. Our drilling campaigns at the West Huntoon copper prospect and the Rhyolite Dome gold prospect were completed as planned, with laboratory assays currently awaited. At West Huntoon and Defender-Pine Crow we have conducted extensive surface sampling and the recent machine-cut channel samples taken at Defender-Pine Crow in December will greatly add to our understanding of the tungsten potential there, which we expect will confirm zones of tungsten mineralisation. We have effectively strengthened our exposure to the minerals that are becoming increasingly important to domestic US supply chains, and we are eager to see the Pine Crow-Defender assay results.
“We will enter the new year well positioned to build on this momentum and unlock value across the portfolio.”
