Vanguard Mining Files First NI 43-101 Technical Report for Redonda, Highlighting Large-Scale Copper-Molybdenum System with Expansion Potential

Executive Summary

• Vanguard Mining filed its first NI 43‑101 technical report for the 100% owned Redonda Copper‑Molybdenum Project, confirming a large‑scale copper‑molybdenum system.
• The report incorporates results from the 2025‑2026 drill campaign and historic Teck Resources drilling, showing mineralization open in multiple directions with near‑surface intercepts exceeding 100 m.
• A two‑phase exploration program is recommended, including IP geophysics, mapping, sampling (Phase 1) and ~2,800 m of diamond drilling across seven holes (Phase 2).

Key Details

• Project Scope: 9 mineral claims covering 2,746.46 ha on West Redonda Island, ~40 km NE of Campbell River, BC; year‑round barge access and logging road infrastructure.
• Geological Setting: Located in the Coast Suture Zone; copper‑molybdenum mineralization associated with a hornblende porphyry dike and breccia zones, consistent with porphyry systems.
• Mineralized Footprint: Approx. 600 m strike × 500 m width × 300 m vertical extent defined by drilling.
• Drill Intercepts: Multiple holes intersected >100 m of continuous copper‑molybdenum mineralization; several intercepts begin near surface, supporting favorable exploration geometry.
• Open‑Ended Potential: Mineralization remains open at depth and along strike, indicating potential for a larger underlying porphyry system.
• Technical Qualified Person: Report prepared by W.B. Lennan, P.Geo., Independent QP under NI 43‑101; reviewed/approved by Lawrence Segerstrom, P.Geo., M.Sc., MBA (non‑independent QP).
• Exploration Recommendations:
• Phase 1: Induced Polarization (IP) survey, detailed surface mapping, geochemical sampling to refine targets.
• Phase 2: ~2,800 m of diamond drilling across seven holes to test priority targets and expand the mineralized envelope.
• Forward‑Looking Statements: Company highlights potential for Redonda to evolve into a significant discovery; acknowledges risks related to exploration results, financing, permitting, commodity prices, etc.

Notable Quotes

“We now have independent confirmation of a large‑scale copper‑molybdenum system at Redonda… mineralization is strong, consistent, and remains open in multiple directions and may represent the upper portion of a much larger porphyry system.” – David Greenway, CEO, Vanguard Mining Corp.
