en.Wedoany.com Reported - Irving Resources Inc. (IRV:CSE; IRVRF:OTCQX) announced on June 25 strong assay results from its Omu Sinter epithermal gold-silver project in Omu, Hokkaido, Japan. Diamond drill hole 26OMS-002, a 53-meter vertical hole, intersected 47.7 meters from the top of bedrock to the bottom of the hole, grading 0.98 g/t gold and 68.96 g/t silver (2.06 g/t gold equivalent). Within this intercept, a 7-meter sub-interval returned 4.05 g/t gold and 54.71 g/t silver; another 1.05-meter sub-interval returned 10.68 g/t gold and 187.81 g/t silver.
The company stated that this marks the first occurrence of such high-grade mineralization in the shallow geological environment of Omu Sinter, and no hydrothermal conduit had been identified at this location prior to hole 26OMS-002. Dr. Quinton Hennigh, Technical Advisor and Director of Irving, said the assay results confirm earlier speculation that a hydrothermal conduit was discovered at the eastern edge of Omu Sinter, with high-grade precious metals appearing in a shallow environment for the first time, suggesting the potential for a larger deposit at depth. Under a strategic partnership with JX Advanced Metals Corporation, which funded the drilling, this is part of a three-year option agreement initiated on November 13, 2024. Under the agreement, JX can earn a 75% interest in the Omu Sinter pit (covering 1.962 square kilometers, extending to approximately 50 meters below sea level), with the primary goal of collecting sufficient technical data to assess whether the deposit can serve as a source of silica flux for Japan's smelting industry.
In early 2026, the company completed two shallow vertical diamond drill holes at the eastern edge of Omu Sinter. Hole 26OMS-001 intersected a 22.18-meter thick layer of siliceous sinter, grading 0.56 g/t gold and 10.36 g/t silver (0.72 g/t gold equivalent). Hennigh noted that in epithermal systems, bonanza grades may occur within the boiling zone, typically at depths of several hundred meters, and the company plans to test the deeper parts of this area through aggressive drilling starting later this year.
At the Shiga exploration area, Irving released in March exploration results from the epithermal gold-silver prospect on the Noto Peninsula in Honshu, Japan. The company's extensive exploration coverage includes 99 Noto exploration licenses, covering four target areas within 337.37 square kilometers known for stream sediment anomalies of gold, silver, arsenic, antimony, mercury, and copper. Upon approval, Irving will become the largest holder of exploration licenses in the Noto region. The Noto project is a joint venture between Newmont Overseas Exploration Ltd., Sumitomo Corp., and Irving, with equity interests allocated as follows: Newmont 60%, Sumitomo 12.5%, and Irving 27.5%. The geological setting of the Noto Peninsula is similar to that of nearby Sado Island, which hosts the Sado Kinzan gold mine, active for 388 years since 1601, producing approximately 2.51 million ounces of gold and 74 million ounces of silver.
Irving's stream sediment survey in northern Noto identified significant gold anomalies in the Shiga exploration area. In October 2025, the company's internal field team conducted extensive ridge and sub-ridge soil and rock chip sampling and geological mapping in Shiga. The latest assay results, processed by ALS Perth and Brisbane, include data from 81 rock chip samples and 150 soil samples, currently under in-depth analysis, which will inform the ongoing exploration and development strategy for the Shiga exploration area.
