CC · Price

Executive Summary

  • Core Silver confirmed a new copper‑bearing porphyry vein system at Copper Creek, extending the Cu‑Mo‑Ag mineralized footprint to >4.5 km across the Laverdiere Copper Project.
  • Surface samples returned high grades (up to 1.35 % Cu with 9.1 g/t Ag; 0.63 % Cu with 17 g/t Ag and 355 ppm Mo).
  • The discovery highlights district‑scale porphyry potential and keeps the system open for expansion in all directions, with further drilling results to follow.

Key Details

  • Location: Lower Copper Creek, ~2.6 km south of the Valley Fault Zone on the Blue Property (Atlin Mining District, BC).
  • Assay Highlights:
  • 1.35 % Cu & 9.1 g/t Ag (surface sample)
  • 0.63 % Cu, 17 g/t Ag & 355 ppm Mo (surface sample)
  • Multiple additional samples showing anomalous Cu‑Mo‑Ag values.
  • Vein Characteristics: Steeply dipping malachite‑chalcopyrite veins cross‑cut by epithermal quartz‑carbonate veining; similar structures observed 1.8 km west at Upper Copper Creek (assays pending).
  • Footprint Expansion: Confirmed Cu‑Mo‑Ag mineralization now spans ~4.5 km from the Main Copper Skarn Zone (North Adit) to Copper Creek, open in all directions.
  • Historical Context: Prior drilling (2022) returned up to 0.90 % Cu with notable Ag and Au; historic adits (early 1900s) reported 1.20 % Cu over 27 m.
  • Future Work: Additional results from the 2025 exploration program, including upcoming drill campaigns, will be released as they become available.
  • Qualified Person: Nicholas Rodway, P.Geo., CEO & Director (NI 43‑101 Qualified Person) reviewed and verified all technical data.

Notable Quotes

“The discovery of a new copper porphyry vein system at Copper Creek marks an important step forward in demonstrating the true scale of the Laverdiere system… These strong surface results, combined with ongoing deep drilling at the Valley Zone, reinforce our view that the Blue Property hosts a district‑scale copper‑molybdenum‑silver system capable of generating significant long‑term value.” – Nick Rodway, President & CEO
