Irving Resources Inc. (CSE: IRV; OTCQX: IRVRF; FSE: 1IR) announced on September 14, 2026 that its 2026 diamond drill program is underway at its Omu gold-silver project in Hokkaido, Japan, with four drill rigs active across multiple targets. The program spans the Nanko target, the JX/Irving collaboration zone within the Omui mining licence, and the Omu Sinter deposit. Investors will be watching for assay results and a pending permit approval that would allow deeper drilling at Omu Sinter's high-grade feeder zone.

Key Points

  • Irving Resources Inc. (CSE: IRV; OTCQX: IRVRF; FSE: 1IR) is a Vancouver-based junior gold explorer focused on Japan.
  • Four diamond drill rigs are now active at the Omu project across the Nanko, Omui collaboration, and Omu Sinter targets.
  • A June 2026 intercept at Omu Sinter graded 0.98 gpt Au and 68.96 gpt Ag over 47.7m, including higher-grade subintervals.
  • Permit approval for deeper drilling at Omu Sinter's feeder zone is expected within weeks, per the announcement.

Four-Rig Campaign Tests Nanko's Shallow Silica-Rich Gold-Silver System

At the Nanko target within the Omui mining licence, Irving's own Zinex A5 diamond drill rig is testing shallow silica-rich gold-silver mineralisation. The company states that recently completed holes have encountered extensive shallow, intensely silicified volcanic rocks, hydrothermal breccias, and veining, with sulphide minerals visible in unoxidised sections. Irving believes a large volume of gold-silver-bearing silica may be present at Nanko and states the current program is designed to outline the footprint of that system. The release notes that drilling five years ago in the area intersected similar geology that proved to contain appreciable gold and silver values.

JX/Irving Collaboration Drilling Advances at Omui Mineralized Zone

Two of the four active rigs are operating within the JX/Irving collaboration area at Omui, following up on earlier drilling that tested silicification and mineralisation at shallow depths. The release states these holes are already showing hydrothermal breccias and veining. The Omu Sinter deposit, also subject to the JX option agreement disclosed in November 2024, is the focus of a fourth rig, which continues to expand the shallow silica sinter footprint through vertical holes. Irving and JX Advanced Metals Corporation are collaborating to define a shallow gold-silver silica deposit with potential as a silica flux source for Japan's smelting industry.

High-Grade Omu Sinter Feeder Zone Awaits Deeper Drill Permit

Irving has filed an application to drill deeper holes at Omu Sinter to test a high-grade feeder zone discovered earlier in 2026. The company's June 25, 2026 release reported an intercept grading 0.98 gpt Au and 68.96 gpt Ag (2.06 gpt AuEq) over 47.7m, including 4.05 gpt Au and 54.71 gpt Ag over 7.0m, with a subinterval of 10.68 gpt Au and 187.81 gpt Ag over 1.05m. The company notes these results are not necessarily representative of mineralisation throughout Omu Sinter. The deeper zone, below approximately 50 metres below sea level, is 100% controlled by Irving and not subject to the JX option agreement. Permit approval is expected within weeks.
