Irving Resources Inc. (CSE: IRV; OTCQX: IRVRF; FSE: 1IR) has announced completion of detailed geological, geochemical, and geophysical surveys at the Unoya target within its Shika epithermal gold-silver project on Japan's Noto Peninsula. The highest-grade float vein sample, NT-0674, returned 62.3 g/t gold and 604 g/t silver, with 13 of 56 quartz vein samples exceeding 1 g/t gold. The joint venture — comprising Newmont Overseas Exploration Limited at 60%, Sumitomo Corporation at 12.5%, and Irving at 27.5% — is now contemplating a potential drilling programme in the Unoya area in 2027.

Key Points

  • Irving Resources Inc. (CSE: IRV; OTCQX: IRVRF; FSE: 1IR) is a Vancouver-based junior gold explorer focused on Japan
  • Geological, geochemical, and drone magnetic surveys completed at the Unoya target, Shika project, Noto Peninsula
  • Top sample NT-0674 returned 62.3 g/t Au and 604 g/t Ag; a depressed magnetic zone measuring approximately 2.5 km by 1.0 km identified
  • Investors may be watching for soil geochemical results and a decision on the contemplated 2027 drilling programme

High-Grade Vein Float and a New Southern Gold Cluster at Unoya

Irving's 2026 field programme identified gold-bearing quartz vein float both near the historical Unoya Mine and within a separate area approximately 1 km further south — a distribution the company's geologists interpret as a potential en echelon vein system linked to an underlying shear structure. Sample NT-0674, collected from the southern area, contains dark silver-rich bands described as "ginguro" and returned values of 62.3 g/t gold and 604 g/t silver. Of the 56 quartz vein and float samples collected during the 2026 programme, 13 returned values greater than 1 g/t gold.

Drone Magnetic Survey Outlines a 2.5 km Prospective Alteration Zone

A high-resolution drone-borne magnetic survey conducted between May 24 and 27, 2026 covered approximately 10 square kilometres across 41 flight lines spaced 100 metres apart, operated by Mitsui Mineral Development Engineering Co., Ltd. The reduced-to-the-pole image reveals a subdued magnetic zone measuring approximately 2.5 km by 1.0 km that closely corresponds with the distribution of gold-bearing quartz vein float and altered rocks. Irving's geologists interpret this feature as reflecting hydrothermal destruction of magnetite within volcanic host rocks — a process directly associated with epithermal gold mineralisation.

Geological Context and Depth Interpretation at the Shika Prospect

Geological mapping conducted from May 8 to 20, 2026 confirmed that silicification and argillic alteration has affected the Early to Middle Miocene Besshodake Andesite and associated pyroclastic and lacustrine rocks throughout the Unoya area. Based on observed vein textures and alteration mineral assemblages, Irving's geologists interpret the current erosional surface as relatively high-level, suggesting the more prospective mineralised zone may occur at depth. The company is therefore considering reconnaissance drill holes ranging from approximately 300 to 500 metres in length, with final parameters subject to integration of all datasets.

Soil Results Pending as JV Considers Next Exploration Phase

A systematic grid-based soil geochemical survey covering approximately 5.4 square kilometres was completed between June 1 and 13, 2026, with 548 samples dispatched to ALS Global in Brisbane. Results remain pending. The Noto Project forms part of Irving's three-project Japanese exploration pipeline alongside the Omu Project in Hokkaido, which has advanced to the resource development stage, and the Yamagano Project in Kyushu, where scout drilling is currently underway. The immediate share price impact was not clear from available public information.
