Vanguard Mining plans phase 2 drilling at Redonda

Executive Summary

• Vanguard Mining Corp. announced the planning of a Phase 2 drill program at its 100%-owned Redonda copper-molybdenum project in British Columbia, consisting of up to seven holes totaling approximately 2,800 meters.
• The release highlights significant 2025 Phase 1 drilling results that expanded the known copper-molybdenum mineralized system, with Hole 25-01 intersecting over 350 meters of higher-grade mineralization and extending the system vertically and laterally.
• The company is prioritizing engagement with the Klahoose First Nation and will evaluate rhenium as a potential byproduct alongside copper and molybdenum.

Key Details

• Phase 2 Drill Plan:
  • Up to 7 diamond drill holes.
  • Total depth of approximately 2,800 meters.
  • Targeting the southeastern portion of the project between and beyond historical Teck drill holes.
  • Includes reconnaissance-scale induced polarization (IP) surveying to vector toward higher-grade zones.
  • Detailed geological mapping and prospecting in the megabreccia zone to identify new targets.
  • Permits are secured; program is on an accelerated timeline for the 2026 season.
• 2025 Phase 1 Drill Results (Hole 25-01):
  • Drilled at a dip of minus 65 degrees; total depth of 510.74 meters.
  • 3.05 m to 29.12 m (27.07 m): Weighted average of 0.3252% Cu and 78 ppm Mo.
  • 37.65 m to 387.70 m (350.05 m): Weighted average of 0.244% Cu and 112 ppm Mo.
  • These intercepts extended the higher-grade mineralized zone by 199.05 meters, more than doubling the length of higher-grade mineralization from 2023 drilling.
  • Whole-hole weighted average: 0.1801% Cu and 86 ppm Mo.
  • Mineralization remains open at depth.
• 2025 Phase 1 Drill Results (Hole 25-02):
  • Drilled vertically, ~30 meters east of 2023 drilling.
  • 3.05 m to 132.00 m (129.26 m): Weighted average of 0.1344% Cu and 128 ppm Mo.
• Historical Context:
  • Historical drilling by Stamper Oil & Gas Corp. intersected up to 142.6 meters grading 0.279% Cu and 0.0281% Mo.
  • Surface sampling returned intervals up to 48 meters grading up to 0.529% copper equivalent.
• Project Details:
  • Redonda project comprises 9 mineral claims (2,746.46 hectares) ~40 km NE of Campbell River, B.C.
  • Geological setting includes Coast suture zone with Early Cretaceous dioritic intrusions; mineralization associated with hornblende-rich dikes.
  • Collaboration with Klahoose First Nation includes local labor, training, and use of Klahoose-affiliated service providers.
  • Consultation with Homalko First Nation concluded; additional drill site permits issued.
• QA/QC:
  • Samples analyzed by ALS Canada Ltd.
  • Protocols included certified reference materials, blanks, and preparation duplicates.
  • No significant contamination or analytical bias detected.

Notable Quotes

• David Greenway, CEO: "The planned phase 2 drill program is a key next step in advancing the Redonda project following the strong results from our 2025 campaign. Drilling significantly expanded the copper-molybdenum mineralized system beyond the 2023 footprint, reinforcing our confidence in its continuity and scale. With permits secured and multiple priority targets defined, we are well positioned to continue advancing Redonda through further drilling in 2026 and unlocking its longer-term potential."
