Vanguard Mining Corp. Reports 2025 Redonda Drill Results; Cross-Section Confirms Copper-Molybdenum System More Than Doubles in Size

Executive Summary

• Vanguard Mining released assay results from Holes 25‑01 and 25‑02, showing extensive copper‑molybdenum mineralization that expands the higher‑grade zone by ~199 m and more than doubles the length intersected in 2023 drilling.
• Hole 25‑01 reached 510.74 m depth with weighted averages of 0.1801 % Cu and 86 ppm Mo overall; key intervals include 27.07 m at 0.3252 % Cu/78 ppm Mo and 350.05 m at 0.244 % Cu/112 ppm Mo.
• Hole 25‑02 (vertical) intersected 129.26 m at 0.1344 % Cu/128 ppm Mo, confirming lateral continuity of the system. The drill permit remains active for continued 2026 exploration.

Key Details

• Hole 25‑01 (dip –65°)
• Interval 3.05–29.12 m (27.07 m): 0.3252 % Cu, 78 ppm Mo
• Interval 37.65–387.70 m (350.05 m): 0.2440 % Cu, 112 ppm Mo
• Full‑hole average (0–510.74 m): 0.1801 % Cu, 86 ppm Mo; total depth 510.74 m
• Hole 25‑02 (vertical) – located ~30 m east of 2023 drill line

• Interval 3.05–132.00 m (129.26 m): 0.1344 % Cu, 128 ppm Mo

• The higher‑grade mineralized zone is now extended an additional 199.05 m, more than doubling the length of high‑grade intercepts identified in 2023 drilling.

• Lower‑grade mineralization continues below the bottom of Hole 25‑01, indicating the system remains open at depth.
• Samples analyzed by ALS Canada Ltd. using ISO/IEC 17025‑accredited methods (ICP‑MS, ICP‑AES) with standard QA/QC protocols (certified reference materials, blanks, duplicates).
• Qualified Person: J.T. Shearer, M.Sc., D.I.C., P.Geo. (NI 43‑101).

Notable Quotes

“These results represent a meaningful step forward for the Redonda Project… confirming continuity and scale. As copper demand continues to grow in support of the global energy transition, results such as these reinforce our belief that Redonda has the potential to host a large copper‑molybdenum system.” – David Greenway, CEO, Vanguard Mining Corp.

Collaboration with Klahoose First Nation emphasized; ongoing engagement and use of local labour/service providers for 2026 drilling.
