Vanguard Mining Completes Drill Program With Assays Now Pending at Redonda Copper-Molybdenum Project, British Columbia

Executive Summary

• Vanguard Mining Corp. completed its Q4 2025 drill program at the Redonda Copper‑Molybdenum Project, achieving a total depth of 511 m using a Boyles T‑75 hydraulic diamond rig.
• The program comprised multiple holes (e.g., Red‑23‑04, Red‑23‑03, Red‑23‑05, etc.) that intersected copper‑molybdenum mineralization; visual observations indicate alteration and sulphide presence, but assay results are still pending.
• Historical drilling data (1979 Teck Corp. holes and 2023 Vanguard holes) were referenced to contextualize the new work, and the company emphasized ongoing collaboration with the Klahoose First Nation and continued geophysical target generation.

Key Details

• Drilling Contractor & Equipment: Paradigm Drilling Ltd. deployed a Boyles T‑75 track‑mounted diamond drill equipped with NQ tooling, capable of >600 m depth.
• Program Depth: Total drilled depth 511 m across the Q4 program.
• Hole Summaries (selected):
• Red‑23‑04: Surface mineralization from 3.1–18.2 m (15.2 m core, 0.452 % Cu, 0.0265 % Mo). Deeper intervals 25.5–97.5 m (72 m core, 0.235 % Cu, 0.0228 % Mo) and 147.8–163.1 m (30.3 m core, 0.212 % Cu, 0.0154 % Mo).
• Red‑23‑03: Surface mineralization 3.1–48.0 m (45 m core, 0.329 % Cu, 0.0265 % Mo); deeper interval 68.8–141.0 m (77.3 m core, 0.323 % Cu, 0.0197 % Mo).
• Red‑23‑05: Surface mineralization 2.7–33.0 m (30.3 m core, 0.213 % Cu, 0.0192 % Mo); deep interval 39.3–182.0 m (142.6 m core, 0.279 % Cu, 0.0281 % Mo).
• Red‑23‑02: Surface mineralization 3.1–111.0 m (108 m core, 0.251 % Cu, 0.0250 % Mo); high‑grade bottom 158.5–169.2 m (10.7 m core, 0.375 % Cu, 0.1377 % Mo).
• Historical Context:
• 1979 Teck Corp. drilling totaled 1,681 m across nine NQ holes; notable historic grades include up to 0.42 % Cu and 0.075 % Mo in shallow intervals.
• 2023 Vanguard drilling added 799.81 m across five holes with comparable copper‑molybdenum values.
• Assay Status: All core has been logged and submitted to ALS Canada Ltd.; assay results are pending, and visual observations are not a substitute for analytical data.
• Geophysical Targeting: Drill locations were selected using the late‑2024 airborne magnetic, gradient, and radiometric survey (Precision GeoSurveys) that identified fault systems, circular magnetic lows, and potassic alteration zones as prospective targets.
• Community Engagement: Vanguard highlighted collaboration with the Klahoose First Nation—prioritizing local labour, training, use of Klahoose‑affiliated service providers, and adherence to cultural heritage and environmental protocols throughout the campaign.
• Qualified Person: J.T. Shearer, M.Sc., D.I.C., P.Geo., reviewed and approved the technical information per NI 43‑101 standards.

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… While we have observed alteration and sulphide mineralization consistent with the known Redonda system, visual observations alone are not indicative of mineralization grades or economic significance.” – David Greenway, CEO

Materiality Assessment: Non‑Material – Neutral (program completion is material for operational tracking but no assay results or resource implications have been disclosed).
