Summary
Sentinel Metals Limited announced a successful maiden drilling at the Columbia Gold-Silver Project in Montana, USA. The diamond drill-hole DDCO26-001 returned an impressive intercept of 46.8 meters at 5.5 grams per tonne gold, including significant high-grade zones. These results confirm the presence of gold in fresh rock beyond the traditional oxide blanket, with core recoveries suggesting potential for deeper mineralisation. The company has improved its drilling techniques for better core recovery and awaits further assay results for additional drill holes. The progress bolsters Sentinel's understanding of the geological characteristics of the Columbia system.
Key Points
  • Sentinel Metals' maiden diamond drill-hole DDCO26-001 at the Columbia Gold-Silver Project in Montana returned 46.8m at 5.5 g/t gold.
  • The drill intersected high grade zones, including 21.4m at 11.1 g/t gold and 13.5m at 16.6 g/t gold.
  • Gold was confirmed in fresh rock below the historical oxide limit with high core recovery, indicating potential for deeper mineralisation.
  • The company has transitioned to triple-tube drilling to improve core recovery and will continue the program with assays for additional holes pending.
  • Managing Director Matt Herbert emphasized the importance of the findings in understanding the Columbia system's geology and improving drilling methods.
