Great Western Mining (GWMOF) reported excellent initial metallurgical test results from its Defender Tungsten Project in Nevada, based on bench-scale flotation work on a 750 kg representative bulk sample grading 0.35% WO₃.
The sequential sulphide pre-float removed sulphide contaminants into just 3.97% of total mass while retaining 99.46% of the tungsten in the main sink at 0.35% WO₃, indicating minimal loss of the target mineral before primary extraction. The subsequent column flotation stage recovered 92.98% of the remaining tungsten into a rougher concentrate grading 7.21% WO₃, representing substantial grade upgrading and a low-volume, clean concentrate with very low deleterious elements such as molybdenum.
The results confirm amenability to established flotation processing and will underpin the next phase of metallurgical work, focused on cleaner circuit optimisation and evaluating a mild regrind stage to move towards potential marketable product specifications.
