Transatlantic Mining Corp. Reports Positive Exploration Results at Monitor Copper-Gold Project

Strategic Insights

— 2 min read

Transatlantic Mining Corp., a Canadian-based emerging precious and base metal explorer, is pleased to provide an update on its exploration activities at the Big Elk and Anvil prospects, key targets within the larger Monitor Copper-Gold Project. Located in Idaho, USA, the project has shown significant prospectivity, with recent exploration results confirming the presence of copper mineralization.

The Company's exploration efforts at the Big Elk prospect have yielded encouraging copper results, with an outcrop sample returning 36.1% copper over 2.6 meters and another gossanous sample yielding 6.6% copper. Initial drilling at Big Elk, totaling 1,100 meters, has confirmed the geometry of known mineralized structures and provided critical insights for future targeting. The drilling also identified multiple copper fissure veins within a complex system at the Anvil prospect, indicating additional veins within the claim block. These results are consistent with the Company's geological understanding of the project and highlight the potential for further exploration and development.

Bernie Sostak, CEO of Transatlantic Mining, expressed his satisfaction with the successful outcomes of the exploration program, stating, "We are very pleased with the successful outcomes of our exploration at Big Elk, which has confirmed our geological understanding and the presence of copper mineralization."

Key Takeaways:

  • The Big Elk prospect has yielded high-grade copper results, with an outcrop sample returning 36.1% copper over 2.6 meters and another gossanous sample yielding 6.6% copper.
  • The initial drill program at Big Elk has confirmed the geometry of known mineralized structures and provided critical insights for future targeting.
  • The drilling at the Anvil prospect has identified multiple copper fissure veins within a complex system, indicating additional veins within the claim block.
  • The exploration efforts at Big Elk have confirmed the striking and dipping of the vein mined along the Big Elk workings.
  • Geophysical programs and future exploration plans are being implemented to further explore the project.

Statistics:

  • The initial drill program at Big Elk consisted of 14 holes, totaling 1,100 meters, designed to test copper anomalism found on earlier surface geological reconnaissance.
  • The drilling intersected voids where historical mining had taken place, providing valuable insights into the geometry and continuity of the veins.
  • The surface sampling across the Big Elk Vein subsurface outcrop yielded results, with grades ranging from 6.6% Cu to 36.1% Cu.
  • The Company has identified multiple copper fissure veins within a complex system at the Anvil prospect.
  • The exploration efforts have confirmed the presence of copper mineralization at both the Big Elk and Anvil prospects.
