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

Executive Summary

• Vanguard Mining Corp. will re‑assay selected drill core from its 2025 program using advanced multi‑element analytical methods to better quantify gold, copper, silver, rare earths and other metals.
• The company announced a Phase 2 drill program for 2026 that may include up to seven diamond holes (~2,800 m) plus IP surveying, detailed mapping and prospecting to expand the known copper‑molybdenum system at Redonda.
• Results from the 2025 drilling (e.g., Hole 25‑01 with continuous mineralization over 510 m) confirm a vertically and laterally extensive Cu‑Mo zone that remains open at depth, supporting continued exploration.

Key Details

• Re‑assaying Plan: Multi‑element analysis using four‑acid digestion with ICP‑MS and ICP‑AES to evaluate Au, Cu, Ag, REE and other elements in previously drilled core.
• Phase 2 Drill Program (2026):
• Fully permitted; up to 7 diamond holes, total ~2,800 m targeting the southeast portion of Redonda beyond historic TECK holes.
• Reconnaissance‑scale Induced Polarization (IP) survey to vector higher‑grade Cu‑Mo zones.
• Detailed geological mapping and prospecting in the megabreccia zone to identify new drill targets.
• Logistics: expanded exploration camp or use of existing floating logging camp; continued collaboration with Klahoose First Nation for labour, training and service provider opportunities.
• 2025 Drill Results (Table 1 Highlights):
• Hole 25‑01: 0–510.74 m interval – Cu 0.1801 % , Mo 86 ppm; continuous mineralization over 27.07 m (3.05–29.12 m) with Cu 0.3252 % , Mo 78 ppm; deeper interval 37.65–387.70 m – Cu 0.2440 % , Mo 112 ppm.
• Hole 25‑02: 3.05–132.00 m – Cu 0.1344 % , Mo 128 ppm.
• Analytical QA/QC: Samples processed by ALS Canada Ltd.; certified reference materials, blanks and duplicates inserted; methods accredited to ISO/IEC 17025.
• Geological Context: Redonda comprises nine claims (2,746.46 ha) within the Coast Suture Zone; mineralization associated with a hornblende‑rich dike and brecciated zones, comparable to other BC porphyry Cu‑Mo systems (OKover, Gambier).
• Permitting & Stakeholder Engagement: Valid drill permit in place; Letter of Support from Klahoose First Nation; Free Use Permit, Drill Permit and IP Exemption from the Ministry of Energy, Mines and Low Carbon Innovation. Ongoing consultation with Homalko First Nation completed.
• Forward‑Looking Statements: Plans subject to financing, commodity price fluctuations, permitting, regulatory and operational risks.
