Executive Summary

  • Vanguard Mining Corp. has engaged a Qualified Person (W.B. Lennan, PGeo) to update the NI 43-101 technical report for its 100%-owned Redonda copper-molybdenum project in British Columbia.
  • The updated report will incorporate data from the recently completed 2025-2026 drill campaign, pending assay results, updated geophysical data, and historical data from Teck Resources Ltd.
  • The company completed a drill program using Paradigm Drilling Ltd., targeting areas beyond historical drilling limits to refine the geological model; core logging observed alteration and sulphide mineralization, but assay results are pending.

Key Details

  • Technical Report Update: Vanguard engaged W.B. Lennan, PGeo, to update the March 15, 2024, NI 43-101 technical report for the Redonda property.
  • Data Inclusions: The update will include:
    • Results from the last two drill campaigns (including pending assays from the 2025-2026 campaign).
    • Updated geophysical data.
    • Historical data from Teck Resources Ltd. (nine NQ-diameter diamond drill holes totaling 1,681 metres in 1979).
  • Drilling Operations:
    • Contractor: Paradigm Drilling Ltd.
    • Equipment: Boyles T-75 hydraulic, track-mounted diamond drill with NQ tooling (capable of depths >600 metres).
    • Status: Drilling completed as planned; core logged and submitted to ALS Canada Ltd. for analysis.
    • Observations: Visual logging noted alteration and sulphide mineralization consistent with the known Redonda system, but these are qualitative and not indicative of grade or economic significance.
    • Assay Status: No assay results received for the 2025 drill program at the time of the release.
  • Historical Context & Precedent:
    • 1979 Teck Resources drilling: 9 holes, 1,681 metres.
    • 2023 follow-up drilling: 5 holes, 799.81 metres.
    • 2024 Historical Results (Stamper Oil & Gas): Intervals up to 142.6 metres grading 0.279% Cu and 0.0281% Mo; surface sampling yielded intervals of 3.1m to 48m grading 0.529% CuEq.
    • Core Verification: The 2024 report author noted that 2023 assays compared closely with 1979 results for hole R-79-2.
  • Geophysics & Targeting:
    • 2024 Airborne Survey: Conducted by Precision GeoSurveys Inc., integrating total magnetic intensity, gradient magnetics, and radiometrics.
    • Findings: Delineated northeast-southwest-trending fault systems, circular magnetic lows (potential intrusive centres), and radiometric potassium anomalies defining potassic-alteration zones.
    • Data Availability: Full airborne data package (GeoTIFF maps) available on company website for reference only.
  • Community Engagement:
    • Priority collaboration with Klahoose First Nation within their traditional territory.
    • Focus on local labour, training, and Klahoose-affiliated service providers.
    • Permitting: Consultation with Homalko First Nation concluded; permit for additional drill sites issued.
  • Project Location & Geology:
    • Location: Vancouver mining division, near Campbell River, B.C. (40 km NE of Campbell River).
    • Size: 2,746.46 hectares across nine mineral claims.
    • Geology: Coast Suture zone between Wrangellia terrane and Coast Plutonic complex. Mineralization concentrated along hornblende dikes, sharing characteristics with nearby OKover and Gambier copper-molybdenum deposits.
  • Qualified Person: J. T. Shearer, MSc, DIC, PGeo (consulting geologist, not at arm's length with Vanguard).
