Irving Resources Updates Exploration Results and Announces Proposed Exploration Plans for the Yamagano Joint Venture, Kyushu, Japan

Executive Summary

• Irving Resources reported assay results from drill hole 25SY‑002A, intersecting a high‑grade gold zone of 2.11 g/t Au over 0.9 m at depth ~838 m, confirming the Yamagano epithermal system extends ≥450 m below historic mining levels.
• The company completed a three‑phase soil sampling program covering ≈5.88 km², collecting 673 soil samples and 57 surface rock samples, with peak assays of 86.8 g/t Au and 43.4 g/t Ag from quartz vein float.
• Irving outlined plans to commence additional drilling in the Yamagano Mining Right during 2026, pending a Master Plan under its option agreement with Shimadzu Ltd., targeting under‑explored southern resistive bodies and covered volcanic sequences.

Key Details

• Drill Hole 25SY‑002A – depth 951.8 m; azimuth 357°, inclination 66°.
• Highest intercept: 2.11 g/t Au from 837.43 m to 838.33 m (0.9 m).
• Multiple anomalous gold‑bearing intervals associated with silicification and stockwork veining throughout the hole.
• Drill Hole 25SY‑003 – depth 900.30 m; azimuth 350°, inclination 53°.
• Targeted same southern resistive feature; assay results pending.
• Logged hydrothermal alteration zones at ~130 m, 300 m, and 625 m.
• Soil Sampling Program (Phases I‑III) – total area ≈5.88 km².
• Samples collected: Phase I = 198 soils + 32 rocks; Phase II = 157 soils + 7 rocks; Phase III = 316 soils + 18 rocks.
• Laboratory analysis: ALS Global (Brisbane) for Phase I soils, Newmont Lab (Denver) for Phases II‑III soils; rock samples analyzed by ALS Global (Perth).
• Peak assay results: 86.8 g/t Au and 43.4 g/t Ag from a quartz vein float sample; Phase I soil highest gold value 7,940 ppb Au (7.94 g/t) and 5.2 g/t Ag.
• Quality Assurance/Control – Certified reference materials (Oreas™) and blank limestone inserted every 20th soil sample (Phase I); duplicate samples for DSG soils (Phases II‑III); blanks & standards for rock batches.
• Future Exploration Plans (2026) –
• Potential drilling within the Yamagano Mining Right held by Shimadzu Ltd., subject to a Master Plan under the existing option agreement.
• Focus on under‑explored southern resistive body and areas covered by Hokusatsu Younger Andesite, which have seen little prior drilling.
• Joint Venture Structure – Yamagano JV: Newmont 60%, Sumitomo 12.5%, Irving 27.5%.

Notable Quotes

• “These results are favourable because they indicate that the Yamagano epithermal gold system extends to depths of at least 450 m below those reached by historical mining operations.” – Akiko Levinson, President, CEO & Director, Irving Resources Inc.
