North Valley Resources Identifies Untested High-Priority Drill Targets with WMX up to 3.2
North Valley Resources’ SWIR analysis of 78 rock‐chip samples at its 4,462-hectare Comstock project in southern British Columbia identified peak WMX values of 3.2, vectoring toward multiple high-priority, untested porphyry-style drill targets. Historical drilling at Original Diane returned up to 0.72 g/t Au and 0.53% Cu over 12.8 m.
1. SWIR Analysis Identifies Key Alteration
North Valley Resources conducted Short-Wave Infrared spectral analysis on 78 rock chip samples across five historic showings at its fully permitted, 4,462-hectare Comstock Copper-Gold Project in southern British Columbia. The study identified peak white mica crystallinity (WMX) values of 3.0–3.2, delineating vectors toward a potential hydrothermal heat source.
2. Historical Sampling Highlights High Grades
Historical drilling at the Original Diane target, located on the margins of a large chargeability anomaly, returned 0.53% Cu and 0.36 g/t Au over 12.8 m, 0.49% Cu and 0.52 g/t Au over 8.23 m, and 0.38% Cu and 0.72 g/t Au over 13.99 m. High-grade rock grab samples returned up to 27.1% Cu and 56 g/t Au, underscoring the potential for near-surface porphyry-style mineralization.
3. Exploration Footprint and Next Steps
Chargeability anomalies identified in geophysical surveys overlap with phyllic alteration zones, refining high-priority drill targets that remain untested at depth. North Valley plans to commence focused drilling on these targets to advance the Comstock project toward resource definition.
