Irving Resources Announces Further Drilling Results at the Yamagano Joint Venture, Kyushu, Japan

Executive Summary

• High‑grade gold–silver intercepts were returned from drill hole 25SY‑003, confirming a potential eastward extension of the historic Yamagano vein system.
• Drill hole 26SY‑001 is currently in progress (~400 m drilled) and is slated for completion to 900 m depth by Q1/Q2 2026, targeting a similar AMT resistive target.
• The Company is evaluating a mid‑2026 drilling program on the Shimadzu Ltd.–owned Mining Right west of the East Yamagano Exploration Right, pending permits.

Key Details

• Hole 25SY‑003 (completed) – north‑oriented, azimuth 350°, dip –53°; collared ~360 m south of hole 23SY‑001. Notable high‑grade intercepts:
• 0.9 m @ 8.91 g/t Au & 31.5 g/t Ag (310.10‑311.00 m)
• 0.55 m @ 10.30 g/t Au & 10.0 g/t Ag (313.25‑313.80 m)
• 1.00 m @ 23.36 g/t Au & 9.12 g/t Ag (434.00‑435.00 m) – includes a sub‑interval of 0.48 m @ 46.10 g/t Au & 16.35 g/t Ag (434.52‑435.00 m)
• Additional lower‑grade intervals reported in hole 25SY‑003 (e.g., 2.50 m @ 1.27 g/t Au, 5.97 g/t Ag; 4.62 m @ 3.55 g/t Au, 8.89 g/t Ag).
• Hole 26SY‑001 (in progress) – south‑oriented, azimuth 178°, dip –67°; depth to date ≈400 m, planned final depth 900 m, expected completion Q1/Q2 2026. Targets a discrete AMT resistive feature similar to that intersected by hole 25SY‑003.
• Potential Shimadzu Mining Right drilling – Mid‑2026 program under consideration pending permit issuance; aims to test historic vein zones within the 400‑year gold production area, where ~50 veins were historically identified. Recent soil sampling shows high‑grade gold float near projected veins.
• Joint Venture Structure: Newmont 60%, Sumitomo 12.5%, Irving 27.5%.
• Technical verification performed by Dr. Quinton Hennigh (qualified person, NI 43‑101).

Notable Quotes

• “Irving considers these results encouraging and there is potential for plans for further drilling to follow up on these results.” – Akiko Levinson, President, CEO & Director.
