Great Western Mining (GWMO ) has released assay results from a machine-cut channel sampling programme conducted at its Defender-Pine Crow project in Mineral County, Nevada.

Four new machine-cut channels were completed in April 2026 at Defender-Pine Crow. 

Channel C intercepted 27 metres grading 0.15% WO3 (tungsten trioxide), including 11 metres at 0.25% WO3. Channel D intercepted five metres at 0.12% WO3. Channel E intercepted three metres at 0.34% WO3. Channel F intercepted 18 metres at 0.15% WO3, including six metres at 0.22% WO3.

The sampling also showed very low concentrations of potential penalty elements. 

Silver mineralisation was found in Channel F, across two intervals of two metres, grading 17.6 grams per tonne and 10.1 grams respectively. 

In addition. infill rock chip sampling between Defender Mine and the company’s M2 copper resource supports the hypothesis that there is a 2-3 km corridor of tungsten mineralisation present. 

Channel and rock chip sampling results will inform the company's fully permitted maiden drilling programme, expected to commence in the coming weeks.

"Following our initial channelling in December 2025, additional machine-cut channelling in April 2026 has confirmed broad and significant tungsten mineralisation at the historic Dough God and Pine Crow mines,” said Great Western chief executive Ed Loye. 

“A further channel at the historic Widowmaker mine, supported by new in-situ rock chip samples, extends the tungsten trend a further one kilometre west from Pine Crow and strengthens our interpretation of a significant at-surface, multi-kilometre tungsten corridor. Silver mineralisation over intervals at Widowmaker is a welcome credit. Notably, elements that could impair tungsten processing such as molybdenum were immaterial in the results. The channel and rock chip sampling results provide important guidance for our maiden drilling campaign beginning in a few weeks’ time."

Good progress from Great Western as it readies itself for the main event: the upcoming drill programme. The market for tungsten remains tight, and Great Western’s ground looks extremely prospective. Not surprising then that the shares have performed well over the past few month, having more than doubled in value since April.
