Great Western Mining (GWMO), the AIM-listed copper-gold-tungsten exploration and development company, has announced assay results from its channel sampling programme on its Defender tungsten project in southwestern Nevada. Two channels (A and B) were cut in December 2025 at Defender and have returned significant tungsten mineralisation up to 16m grading 0.30% WO3 (tungsten trioxide), including 2m grading 0.66% WO3 from Channel B.
