About this update from Sumitomo Chemical India Ltd.

VANCOUVER, BC / ACCESS Newswire / September 10, 2025 / Irving Resources Inc. CSE:IRV(OTCQX:IRVRF) ("Irving" or the "Company") is pleased to announce that diamond drill hole 25SY-001 completed at the East Yamagano Joint Venture (the "JV") has encountered multiple mineralized vein zones.

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 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 gpt Au including 1.0 metre grading 8.3 gpt Au starting at a downhole depth of 444.0 metres,1.2 metres grading 4.14 gpt Au including 0.5 metre grading 8.38 gpt Au starting at a downhole depth of 490.8 metres, and2.0 metres grading 2.48 gpt Au including 1.0 metre grading 4.53 gpt 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.
