Vanguard Mining continues drilling at Redonda

Executive Summary

• Vanguard Mining Corp. reports that its ongoing drilling program at the 100%-owned Redonda copper-molybdenum project in British Columbia has surpassed 500 metres in total depth.
• The company is executing an aggressive 2025 exploration program guided by late 2024 airborne geophysical surveys and historical data, with a focus on defining the extent of the mineralized system at depth and exploring district-scale potential.
• Recent drilling results include intervals up to 142.6 metres grading 0.279% Cu and 0.0281% Mo, while surface sampling has yielded near-surface intervals grading up to 0.529% CuEq.

Key Details

• Drilling Progress: Total drilling has surpassed 500 metres; the program is currently permitted for up to 10 drill sites.
• Equipment: Paradigm Drilling Ltd. is deploying a Boyles T-75 hydraulic, track-mounted diamond drill with NQ tooling, capable of testing targets to depths exceeding 600 metres.
• Recent Assay Results:
  • Drill intervals up to 142.6 metres (467.8 feet) grading 0.279% copper (Cu) and 0.0281% molybdenum (Mo).
  • Surface sampling yielded near-surface intervals ranging from 3.1 metres to 48 metres grading 0.529% copper equivalent (CuEq).
  • 2023 drilling bottomed on mineralization at less than 200 metres.
• 2025 Program Scope:
  • Focus is on detailed geological mapping of brecciation trends and deeper drilling below 500 metres within the known potassic core.
  • Mineralized zones remain open to the north and south, with potential extensions along an old road system approximately one kilometre to the northwest.
  • Southern plunge beneath the Coast plutonic complex will be assessed with additional geophysics and drilling.
  • Extensive iron skarns on the east side of Redonda Island are being evaluated as part of a larger magmatic-hydrothermal system.
• Geophysical Data: Drill targets were selected using a late 2024 airborne geophysical survey integrating total magnetic intensity, gradient magnetics, and radiometrics. This survey identified a northeast-southwest-trending fault system and radiometric potassium anomalies defining arcuate potassic-alteration zones.
• Sample Processing: Core logging is conducted by an independent, certified senior geologist. Half of the expected drill core samples have been submitted to ALS Laboratories under strict chain-of-custody protocols.
• Community Engagement: The company is collaborating with the Klahoose First Nation, prioritizing local labour, training, and the use of Klahoose-affiliated service providers. Consultation with the Homalko First Nation has concluded, with a permit for additional drill sites issued.
• Project Location: Redonda project comprises nine mineral claims totalling 2,746.46 hectares, located approximately 40 kilometres northeast of Campbell River, B.C.

Notable Quotes

• "Drilling is progressing well at Redonda and samples have now been shipped for analysis. Early indications continue to reinforce the potential scale of the mineralized system. This year's program builds on previous work... Our focus for the 2025 season is straightforward: expand on the encouraging 2023-2024 results and begin defining the true extent of the Redonda system at depth." — David Greenway, CEO
