Vanguard Mining files NI 43-101 report for Redonda

Executive Summary

• Vanguard Mining Corp. has filed its first National Instrument 43-101 technical report for the 100%-owned Redonda copper-molybdenum project in British Columbia.
• The report validates a large-scale, near-surface porphyry-style copper-molybdenum system with significant expansion potential, defined by a mineralized footprint exceeding 600m in strike, 500m in width, and 300m vertically.
• The company has outlined a two-phase exploration strategy, including geophysical surveys and approximately 2,800 metres of planned diamond drilling to test priority targets and expand the known mineralization.

Key Details

• Project Location: Redonda project comprises 2,746.46 hectares across nine mineral claims on West Redonda Island, approximately 40 km northeast of Campbell River, B.C.
• Geological Setting: Located within the Coast suture zone between the Wrangellia terrane and the Coast plutonic complex; mineralization is associated with a hornblende porphyry dike and breccia zones.
• Data Sources: The report integrates results from Vanguard’s 2023-2026 drill programs, reassaying of legacy core, updated geophysical data, and historical drilling by Teck Resources Ltd. (1979).
• Mineralized Footprint: Drilling outlines a system exceeding ~600 metres in strike, 500 metres in width, and 300 metres vertically.
• Intersect Characteristics: Multiple drill holes intersected long intervals of mineralization, including zones exceeding 100 metres in length with consistent grades. Mineralization is near-surface and remains open in multiple directions (depth and along strike).
• Geological Model: Interpreted as a multiphase intrusive and breccia-hosted porphyry system; current drilling may represent the upper portion of a larger hydrothermal system with potential for a more robust core at depth.
• Exploration Strategy (Phase 1): Induced polarization geophysical survey, detailed mapping, and geochemical sampling to refine drill targets.
• Exploration Strategy (Phase 2): Approximately 2,800 metres of diamond drilling across seven holes to test priority targets and expand mineralization.
• Qualified Person: W.B. Lennan, PGeo, of Port Coquitlam, B.C. (Independent).
• Disclaimer: Management cautions that presented drill sample results are historical in nature; Vanguard has not independently verified previous exploration work. Insufficient exploration has been completed to define a mineral resource.

Notable Quotes

• "This report represents a major milestone for Vanguard... We now have independent confirmation of a large-scale copper-molybdenum system at Redonda, supported by both historical and modern drilling. Importantly, mineralization is strong, consistent and remains open in multiple directions, and may represent the upper portion of a much larger porphyry system." — David Greenway, Chief Executive Officer
