Core Silver samples 316 g/t Ag, 0.62% Cu at Laverdiere

Executive Summary

• Core Silver Corp. released surface rock sample assay results from the Laverdiere copper project, highlighting high-grade porphyry copper-molybdenum-silver mineralization at the Valley Zone and new discoveries at Copper Creek.
• The company outlined its 2025 exploration program, which includes diamond drilling at Laverdiere and the Jackie target at the Silver Lime project, supported by structural mapping and soil grid surveys.
• High-grade mineralization is now confirmed over a 4.4-kilometer corridor extending from the Main zone to Copper Creek, with multiple new targets identified for upcoming testing.

Key Details

• Valley Zone Rock Samples:
  • Sample F421663: 0.62% Copper, 316 g/t Silver, 7,770 ppm Molybdenum.
  • Sample F421662: 0.47% Copper, 187 g/t Silver, 682 ppm Molybdenum.
  • Sample F421657: 0.74% Copper, 50 g/t Silver, 320 ppm Molybdenum, 0.71 g/t Gold.
• Copper Creek Discovery:
  • Located 2.3 km south of the Valley fault; exposed porphyry copper-molybdenum-silver veining and epithermal stockwork.
  • Sample F421677: 0.63% Copper, 17 g/t Silver, 355 ppm Molybdenum.
  • Vein system mapped and sampled for over 200 meters of exposed strike length.
• Project Extent:
  • High-grade porphyry copper-molybdenum-silver-plus-or-minus-gold mineralization confirmed over a 4.4-kilometer corridor from the Main zone to Copper Creek.
  • Mineralization remains open for expansion in all directions and at depth.
• 2025 Program Plans:
  • Diamond drilling at Laverdiere supported by prospecting and drone-assisted structural mapping.
  • 5.5 km by 2.5 km soil grid across key target areas.
  • Diamond drilling planned for the Jackie target at the Silver Lime polymetallic project.
  • New 3-D geological model developed for Silver Lime; numerous high-grade silver targets being considered.
• Historical Context (Laverdiere):
  • 1974 drilling reportedly returned 175m of 0.27% Cu (including 6m of 1.60% Cu).
  • 2022 inaugural drilling returned up to 48.5m of 1.02% CuEq from hole LAV22-001.
  • 2024 mapping at Valley Zone identified sheeted mineralized porphyry veins over a 1-km east-west trend.

Notable Quotes

• "Two thousand twenty-five marks another exciting year for Core Silver as we continue drilling at the Laverdiere copper project. With high-grade copper and silver mineralization confirmed for over four kilometres and multiple new targets now ready to be tested, we see significant potential for both scale and grade. Our goal this season is to demonstrate that the Blue property hosts multiple district-scale and robust polymetallic systems capable of delivering long-term value for shareholders." — Nick Rodway, President and CEO
