Irving Resources Receives Assay Results from Its Shika Epithermal Au-Ag Prospect and Announces Its 2026 Exploration Plans for the Noto Peninsula, Honshu, Japan

Executive Summary

• Irving Resources released assay results from 81 rock chip samples and 150 soil samples collected at the Shika epithermal gold‑silver prospect (historical Unoya Mine) on Japan’s Noto Peninsula.
• Four high‑grade quartz vein float samples returned >1 g/t Au, with the highest reported values of 38.5 g/t Au (45.6 g/t Ag) and 9.33 g/t Au (12.6 g/t Ag).
• Soil assays show a maximum Au concentration of 126 ppb and elevated pathfinder elements (Ag up to 0.21 ppm, Hg 0.62 ppm, Sb 3.43 ppm, As 257 ppm, Se 3.08 ppm), outlining a geochemical halo along the Togigawa Fault.

Key Details

• Project Scope: 99 Noto prospecting licenses (337.37 sq km) covering four target areas; joint‑venture partners: Newmont (60%), Sumitomo (12.5%), Irving (27.5%).
• Sampling Program: October 2025 field work – ridge‑and‑spur soil and rock chip sampling; 81 rock chips, 150 soils sent to ALS Global (Perth & Brisbane) for analysis.
• High‑Grade Rock Samples:
• Sample NT‑0486 – Au 38.5 g/t, Ag 45.6 g/t (50–60 cm × 40–30 cm quartz vein breccia float).
• Sample NT‑0485 – Au 9.33 g/t, Ag 12.6 g/t (massive to brecciated quartz vein float).
• Other Notable Rock Intercepts: Several quartz vein float samples >1 g/t Au distributed over ~1.2 km strike length along the eastern Togigawa Fault.
• Soil Geochemistry: Maximum Au 126 ppb; elevated Ag (0.21 ppm), Hg (0.62 ppm), Sb (3.43 ppm), As (257 ppm), Se (3.08 ppm). Anomalies concentrate around the historical Unoya Mine and diminish outward, following NNE‑SSW to NE‑SW structural trends.
• Planned 2026 Work: Mid‑year continuation of field mapping; drone‑borne high‑resolution magnetic survey (100 m line spacing) over a 4.0 km × 2.5 km area encompassing the high‑grade corridor and geochemical anomalies, with lines oriented perpendicular to the Togigawa Fault strike.
• QA/QC Procedures: Interchanging OREAS™ blanks & standards every 20th sample; rock fire assay (50 g) with ICP‑AES finish; soils screened to 180 µm, 50 g charge for trace Au and multi‑element analysis; all labs at arm’s length.
• Qualified Person: Dr. Quinton Hennigh, Ph.D., P.Geo., qualified person under NI 43‑101, director & technical advisor of Irving, reviewed and approved the technical information.

Notable Quotes

• “The high‑grade vein float samples and strong soil anomalies confirm the presence of a low‑sulfidation epithermal system along the Togigawa Fault, providing a solid foundation for further exploration targeting.” – Dr. Quinton Hennigh, Qualified Person.
