Vanguard Mining Launches 2025 Redonda Follow-Up Drill Program After 174.1 m at 0.34% CuEq From Surface

Executive Summary

• Vanguard Mining Corp. announces the commencement of its 2025 Diamond Drill Program at its 100% owned Redonda Copper-Molybdenum Project in British Columbia.
• The program is guided by recent Precision GeoSurveys airborne geophysical data and aims to test strong targets identified from previous drilling and surveys, with a focus on defining the size of the system and exploring extensions.
• The project is fully permitted and funded, with plans for up to 10 drill sites, including deep drilling below 500 meters and geological mapping of brecciation trends.

Key Details

• Project Status: The Redonda Project (2,746.46 hectares) is fully permitted for drilling and fully funded for the 2025 exploration program.
• Drill Program Scope: The 2025 program includes detailed geological mapping of brecciation trends and deeper drilling below 500 meters within the known potassic core.
• Target Areas: Mineralized zones remain open to the north and south, with potential extensions along an old road system 1 km to the northwest. Airborne geophysics and subsequent drilling are warranted to the south where mineralization may plunge beneath the Coast Plutonic Complex. Extensive iron skarns on the east side of Redonda Island may represent part of a larger magmatic-hydrothermal system.
• Previous Results (2023/Historic):
  • Hole Red-23-05: Returned 142.6 meters grading 0.279% Cu and 0.0281% MoS2.
  • Hole Red-23-03: Returned 45.0 meters grading 0.329% Cu and 0.0265% MoS2 starting from surface.
  • Hole Red-23-02: Returned 108 meters grading 0.251% Cu and 0.025% MoS2 starting from surface.
  • Historic Hole DOH R79-3: Returned a 174.1-meter interval grading 0.204% Cu, 0.012% MoS2, and 0.340% CuEq starting from surface.
  • Historic Hole DOH R79-5: Returned a 207.3-meter interval grading 0.204% Cu, 0.012% MoS2, and 0.277% CuEq.
• Geophysical Data: The 2024 airborne survey integrated total magnetic, gradient magnetic, and radiometric datasets, revealing correlations with mapped geological domains, including a northeast-southwest fault system and circular magnetic lows linked to intrusive centers. Radiometric potassium data highlights arcuate potassic alteration zones.
• QA/QC: Analytical work completed by ALS Canada Ltd. (ISO/IEC 17025 accredited). Samples prepared via fine crushing and pulverizing; gold determined by PGM-ICP24 (fire assay with ICP-AES finish); multi-element data by ME-MS61 (four-acid digestion with ICP-AES and ICP-MS).

Notable Quotes

• David Greenway, CEO: “Kicking off our 2025 work at Redonda is a big step for Vanguard. We have our permits in place, the budget secured, and we’re moving ahead with a deep drilling program to test the strongest targets from our recent surveys and drilling. Past work delivered standout results, including a long 174-metre zone starting right at surface and strong surface samples around 0.5% copper-equivalent—giving us clear places to drill deeper and expand. We’re operating in British Columbia, which is open for responsible development, and the Government of Canada’s new Major Projects Office, set up as a single, fast-track point of contact, shows a real commitment to getting important projects built. With these tailwinds, our goal this season is to build on the discovery outlined in 2023–2024 and start defining the true size of the system.”
