Vanguard Mining completes Q4 drilling at Redonda

Executive Summary

• Vanguard Mining Corp. has completed its Q4 2025 drill program at the 100%-owned Redonda copper-molybdenum project in British Columbia, drilling a total of 511 metres.
• Assay results for the 2025 program are currently pending; no laboratory analytical results have been received at the time of the release.
• The drilling targeted areas beyond historical limits based on 2024 airborne geophysical surveys, with visual observations showing alteration and sulphide mineralization consistent with the known system, though grades remain unverified.

Key Details

• Drilling Completion: Total depth of 511 metres drilled during the Q4 2025 program.
• Contractor & Equipment: Paradigm Drilling Ltd. deployed a Boyles T-75 hydraulic, track-mounted diamond drill with NQ tooling.
• Assay Status: Core has been logged and submitted to ALS Canada Ltd. for analysis using industry-standard QA/QC procedures (including blanks and standards). Results are pending.
• Historical Context:
  • 1979 Teck Resources drilling: 9 holes, 1,681 metres total.
  • 2023 follow-up drilling: 5 holes, 799.81 metres total.
  • Historical intervals included up to 142.6 metres grading 0.279% Cu and 0.0281% Mo.
  • Surface sampling yielded near-surface intervals of 3.1 to 48 metres grading up to 0.529% CuEq.
• Geological Targets: Targets were derived from a late 2024 airborne geophysical survey (total magnetic intensity, gradient magnetics, radiometrics). Key features include a northeast-southwest-trending fault system and circular magnetic lows interpreted as potential intrusive centres. Radiometric potassium anomalies define arcuate potassic alteration zones.
• Community Engagement: Priority placed on collaboration with Klahoose First Nation, including local labour, training, and use of Klahoose-affiliated service providers. Consultation with Homalko First Nation concluded, with permits issued for additional drill sites.
• Project Location: Redonda project comprises 9 mineral claims (2,746.46 ha), located ~40 km northeast of Campbell River, B.C., within the Coast Suture zone.

Notable Quotes

• "The 2025 drill program was designed to test targets beyond the limits of historical drilling and to improve our understanding of the geological framework at Redonda. Drilling has been completed as planned, and all core has been logged and submitted for analysis." — David Greenway, CEO
