Irving Resources Updates Progress on its Extensive Epithermal Gold-Silver Holdings, Noto Peninsula, Honshu, Japan

Executive Summary

• Irving Resources provided a detailed update on its epithermal gold‑silver exploration program across the Noto Peninsula, Japan, including recent rock chip and soil sampling activities.
• Significant multi‑element anomalies were reported, notably a 54.7 ppb Au sample (with elevated Ag, Hg, Sb, As) from the Mii area and other high‑grade samples from Shika, Wajima, and Najimi prospecting rights.
• All field work was conducted by the company’s Japanese subsidiary between June 2024 and October 2025; analytical results for Central and Northeast Noto have been received, while Southwest Noto results are pending.

Key Details

• Project Scope: 99 Noto prospecting licenses covering 337.37 km²; joint‑venture ownership – Newmont 60%, Sumitomo 12.5%, Irving 27.5%.
• Sampling Program:
• Total of 106 surface rock chip samples and 528 surface soil samples collected to date.
• Soil sampling employed a ridge‑and‑spur technique on 40 ridgelines at 100 m spacing.
• Southwest Noto – Shika Prospecting Right:
• 19 blocks granted by METI (Oct 2025).
• 81 rock chip and 150 soil samples collected; analytical results pending.
• Historical Unoya gold mine area sampled; quartz veins with pyrite disseminations identified.
• Central Noto – Wajima, Wajima South & Mii:
• Highest individual soil Au concentration: 54.7 ppb (Mii) with Ag 0.1 ppm, Hg 16.8 ppm, Sb 42.6 ppm, As 1,935 ppm.
• Wajima area sample: Au 4.7 ppb; associated trace elements moderately elevated.
• Northeast Noto – Najimi:
• Maximum soil Au concentration: 7.4 ppb; accompanying Ag 0.4 ppm, Hg 0.2 ppm, Sb 1.3 ppm, As 23.5 ppm.
• Hydrothermally altered rocks mapped; mineralization likely buried beneath sedimentary cover.
• Quality Assurance/Control: Interchanging Oreas™ blanks and standards inserted every 20th sample; duplicates taken every 75th sample for Central and Northeast Noto.
• Laboratory Analysis: Rock chips sent to ALS Global (Perth); soil samples to ALS Global (Brisbane).
• Qualified Person: Dr. Quinton Hennigh, Ph.D., P.Geo., qualified person under NI 43‑101, reviewed and approved all technical information.

Notable Quotes

• “Given the extensive scope of the Unoya historical mine, proximal occurrences of quartz vein float and appreciable clay + silica alteration observed throughout the area, Irving's geologic team believes the Shika area warrants more follow up to better evaluate the full extent of the Unoya vein system.” – Dr. Quinton Hennigh, Qualified Person
