Irving drills five m of 2.9 g/t Au at East Yamagano

Ms. Akiko Levinson reports IRVING ENCOUNTERS MULTIPLE GOLD VEINS IN LATEST DIAMOND DRILL HOLE AT EAST YAMAGANO, JAPAN Diamond drill hole 25SY-001 completed at Irving Resources Inc.'s East Yamagano joint venture has encountered multiple mineralized vein zones. Significant assays are tabulated below. Hole 25SY-001 is oriented in a southerly direction at a steep inclination of 82 degrees reaching a depth of 752 metres. This hole is drilled from the same drill pad as hole 24SY-001, a southerly oriented, 702.1-metre-long hole drilled at a shallower inclination of 65 degrees. Hole 24SY-001 encountered anomalous gold mineralization discussed in the company's news release dated May 5, 2025. Given the strong geologic indicators observed in hole 24SY-002 as well as the presence of a deeper resistive feature evident in AMT (audio-frequency magnetotelluric) data, the JV geologic team thought that drilling a steeper hole in this same location was warranted, hence the reasoning behind drilling hole 25SY-001. As hoped, hole 25SY-001 encountered higher-grade gold values than its shallower counterpart, hole 24SY-001. Discreet zones of gold-rich stockwork veining include: 5.0 metres grading 2.90 grams per tonne gold, including 1.0 metre grading 8.3 g/t Au, starting at a downhole depth of 444.0 metres; 1.2 metres grading 4.14 g/t Au, including 0.5 metre grading 8.38 g/t Au, starting at a downhole depth of 490.8 metres; 2.0 metres grading 2.48 g/t Au, including 1.0 metre grading 4.53 g/t Au, starting at a downhole depth of 678.0 metres. True widths of these structures cannot be determined at this time. In addition to higher gold values, the degree of silicification in hole 25SY-001 is notably higher than that observed in hole 24SY-001. Current thinking by Irving's geologic team is that potential remains for improved gold grades as well as structural widths of vein zones deeper within the AMT resistive zone in this area. Consideration is being given to potentially conducting further drilling in this area. The JV recently completed drilling a 951.8-metre-deep diamond drill hole, 25SY-002A, collared approximately 1.07 kilometres south of 25SY-001. Hole 25SY-002A is oriented northward of 357 degrees at an inclination of 66 degrees. Although the targeted resistive zone here is distinct from that tested farther north, the concept that this feature is related to hydrothermal silicification related to gold mineralization is the same. Significant silicification, silica breccias and stockwork vein zones were notably abundant over the deepest 300 metres of this hole. Given the horizontal distance between the end of hole 25SY-002A and holes farther north is over 700 metres, this opens up the possibility that there exists a corridor of prospectivity for vein mineralization trending through this area. Hole 25SY-002A is in the final stages of logging, splitting and sampling. Assays are expected later this year. The phase II drilling has commenced, utilizing Japan-based drilling contractor Mitsui Mineral Development Co. Ltd. (Mindeco). "Hole 25SY-001 gives us confidence that we have a vein system emerging at depth in this area," commented Dr. Quinton Hennigh, director and technical adviser to Irving. "As hoped, gold grades are substantially higher in hole 25SY-001 than those observed in hole 24SY-001. We now see a vector pointing to potentially higher gold grades and wider vein zones associated with the deeper core of the AMT resistor. We eagerly await results from our newest hole, 25SY-002A, in which we observed silicification, silica breccias and stockwork vein zones at depth. The veining in this hole, coupled with results from holes further north, indicates we may have found extensions of the Yamagano vein system trending through East Yamagano." East Yamagano is a joint venture between Newmont Overseas Exploration Ltd., a wholly owned subsidiary of Newmont Corp., Sumitomo Corp. and Irving. The initial interests of the parties in the joint venture are Newmont 60 per cent, Sumitomo 12.5 per cent and Irving 27.5 per cent. All samples discussed in this news release are one-half split-sawn diamond core samples. Irving submitted samples to ALS Global, Brisbane, Australia, for analysis. Au and Ag were analyzed by fire assay with AA finish. Overlimit samples were assayed by fire assay with gravimetric finish. Multielements were analyzed by mass spectrometry following four-acid digestion. Irving routinely inserts standard and blank samples in assay batches submitted to the laboratory. Company staff are responsible for geologic logging and sampling of core. Au equivalent is calculated by adding Au (g/t) to Ag (g/t) divided by 80. Results referred to in this news release are not necessarily representative of mineralization throughout the project.

Dr. Hennigh is a technical adviser and a director of Irving and has verified the data disclosed, including sampling, through review of photographs of core prior to and after sawing and sampling, and analytical, through review of standard and blank analyses.
