American Tungsten Reports Significant Tungsten in Underground Sampling
Executive Summary
- American Tungsten reports high‑grade tungsten–silver assay results from underground channel samples at the IMA Mine (average 1.04 % WO₃ and 2.70 oz/t Ag over a 5 ft width).
- Surface rock‑chip sampling confirms extension of mineralized quartz veins beyond the primary mine area, with notable intercepts such as 0.256 % WO₃ & 0.64 oz/t Ag over 10 ft and 0.164 % WO₃ & 1.28 oz/t Ag over 6.7 ft.
- Preliminary tailings sampling shows measurable tungsten‑silver grades (average 0.235 % WO₃ & 0.45 oz/t Ag), prompting additional metallurgical testing and further exploration work.
Key Details
- Underground Channel Sampling – No. 5 Vein
- 15 samples collected on D level; weighted average 1.04 % WO₃, 2.70 oz/t Ag over ~5 ft width.
