Vanguard Mining Reports Re-Assay Program for Redonda Copper-Molybdenum Project

Executive Summary

• Vanguard Mining will re‑assay selected drill core from its 2025 Redonda Copper‑Molybdenum drill program using multi‑element ICP‑MS/ICP‑AES methods to better quantify Cu, Mo, Au, Ag, REE and other metals.
• The company is planning a Phase 2 exploration program in 2026 that includes up to seven diamond holes (≈2,800 m), IP surveying, detailed mapping, and continued engagement with the Klahoose First Nation.
• 2025 drill results showed continuous copper‑molybdenum mineralization over >500 m depth at Hole 25‑01, confirming a vertically extensive system that remains open at depth.

Key Details

• Re‑assaying Scope: Multi‑element analysis (four‑acid digestion) of selected core to refine CuEq values and assess gold, silver, rare earths, rhenium and other by‑products.
• Phase 2 Drill Program Highlights:
• Fully permitted; target up to 7 diamond holes totaling ~2,800 m in the southeast Redonda area.
• IP (Induced Polarization) survey to vector higher‑grade Cu‑Mo zones.
• Detailed geological mapping of megabreccia zone for new drill targets.
• Logistics: expanded camp or use of existing floating logging camp; partnership with Klahoose‑owned service providers.
• 2025 Drill Results (Table 1 Summary):
• Hole 25‑01 (−65°) – 27.07 m interval, Cu 0.3252 %, Mo 78 ppm (3.05–29.12 m).
• Hole 25‑01 – 350.05 m interval, Cu 0.2440 %, Mo 112 ppm (37.65–387.70 m).
• Hole 25‑01 – 510.74 m interval, Cu 0.1801 %, Mo 86 ppm (0.00–510.74 m).
• Hole 25‑02 (vertical) – 129.26 m interval, Cu 0.1344 %, Mo 128 ppm (3.05–132.00 m).
• Analytical QA/QC: Samples processed by ALS Canada Ltd.; certified reference materials, blanks, and duplicates inserted; methods accredited to ISO/IEC 17025.
• Permitting & Stakeholder Engagement: Valid drill permit in place; Letter of Support from Klahoose First Nation; free‑use, drill, and IP exemption issued by provincial ministry; ongoing consultation with Homalko First Nation completed.
• Forward‑Looking Statements: Plans contingent on commodity prices, financing availability, permitting, and exploration results.
