Vanguard Mining Engages Qualified Person to Update NI 43-101 Technical Report for Redonda Copper-Molybdenum Project, British Columbia
Executive Summary
- Vanguard Mining engaged W.B. Lennan, P.Geo to update its March 15 2024 NI 43‑101 technical report for the Redonda Copper‑Molybdenum Project, incorporating data from the 2025‑2026 drill campaign and historic datasets.
- The 2025‑2026 drill program (five holes, 799.81 m) was completed as planned; core has been logged and samples submitted to ALS Canada for assay analysis (results pending).
- Visual observations confirm alteration and sulphide mineralization consistent with the Redonda system, but no quantitative assay results are available yet.
Key Details
- Technical Report Update – W.B. Lennan, P.Geo will revise the March 15 2024 report to include:
- Results from the recent 2025‑2026 drill campaign (assays pending).
-
Updated geophysical data and historic drilling information from Teck Resources (1979 nine NQ‑diameter holes, 1,681 m).
-
Drill Program Execution – Paradigm Drilling Ltd. deployed a Boyles T‑75 hydraulic, track‑mounted diamond drill with NQ tooling capable of >600 m depth.
- 2023 Exploration Program (historical context) – Five holes (799.81 m) with reported intercepts:
| Hole | Depth Interval (m) | Core Length (m) | Cu % | Mo % | Re (ppm) |
|---|---|---|---|---|---|
| Red‑23‑04 – surface start | 3.1‑18.2 | 15.2 | 0.452 | 0.0265 | 0.1053 |
| Red‑23‑04 | 25.5‑97.5 | 72.0 | 0.235 | 0.0228 | 0.1106 |
| … (additional intervals listed in release) |
- Historic 1979 Teck Drilling – Nine NQ holes, total 1,681 m; key historic intercepts include:
- DOH R79‑2 (110‑200 m): Cu 0.21 %, MoS₂ 0.019 %
- DOH R79‑5 (92.5‑135 m): Cu 0.20 %, MoS₂ 0.038 %
-
Other holes with Cu 0.06‑0.42 % and MoS₂ 0.004‑0.120 % reported.
-
Assay Status – All core from the 2025‑2026 program has been logged; samples sent to ALS Canada for laboratory analysis. No assay results received at time of release.
-
Community Engagement – Vanguard is collaborating with the Klahoose First Nation, prioritizing local labour, training, and use of Klahoose‑affiliated service providers. Ongoing cultural heritage and environmental protocols are being observed.
-
Geophysical Context – Late‑2024 airborne magnetic, gradient, and radiometric survey identified:
- NE–SW trending fault system with right‑lateral offset.
- Circular magnetic lows interpreted as potential intrusive centres.
-
Potassic alteration zones defining target vectors for drill hole selection.
-
Qualified Person – Review and approval of technical information by J.T. Shearer, M.Sc., D.I.C., P.Geo (Qualified Person under NI 43‑101).
