Resource drilling targets tungsten corridor ahead of maiden MRE in Q4 2026
Great Western Mining Corporation (AIM: GWMO) has commenced drilling at its Defender Tungsten Project in Nevada, targeting a maiden Mineral Resource Estimate before the end of 2026.
The fully funded programme will comprise at least 7,000 feet, or 2,135 metres, of drilling across up to 22 holes, initially testing a 600-1,000 metre corridor covering the Pine Crow, Dough God and Defender historic tungsten mines.
The drilling is designed to establish the continuity and grade of tungsten mineralisation and generate the data required for the planned JORC Mineral Resource Estimate in Q4 2026.
HIGHLIGHTS
- Drilling underway to test grade an initial 600-1,000 metre corridor encompassing the Pine Crow, Dough God and Defender tungsten mines, collectively components of the Defender Tungsten Project.
- Fully funded and on track to deliver a maiden Mineral Resource Estimate (“MRE”) by the end of 2026, incorporating results from a minimum 7,000 feet (2,135 metre) drilling programme.
- CEO Ed Loye and Lewis Harvey of Addison Mining Services (“Addison”), the independent Competent Person for the maiden JORC MRE, are on site for the start of drilling.
- Drill assay results expected through September and October 2026.
- Q2 2026 bulk sample metallurgical results expected in August 2026.
Independent consultancy Addison Mining Services has been appointed as Competent Person for the resource estimate, with Principal Geologist Lewis Harvey on site overseeing logging, sampling, data capture and quality assurance.
Drill assay results are expected through September and October, while results from a separate 750kg metallurgical bulk sample sent for flotation testing are expected during August.
Chief Executive Ed Loye said the start of drilling follows extensive preparatory work including geophysics, geological mapping, sampling and drill pad construction, and keeps the company on track for a maiden resource by year-end.
