Irving Resources Inc. announced that it has discovered a new high-grade vein system in an area approximately 300 m west of Hokuryu historic mine site and encountered substantial veining in a newly drilled diamond drill hole at Omui, both areas part of its 100% controlled Omu Au-Ag Vein Project, Hokkaido, Japan. Major New Vein System Discovered at Hokuryu Historic Mine Site: Hole 22HKR-001 completed at Hokuryu in late 2022 encountered a new high-grade Au-Ag vein system nearly 300 m west-northwest of know underground mine workings. These veins were intercepted near the top of the hole and occur within a broad envelope of mineralization extending 33m grading 1.35 gpt Au and 15.45 gpt Ag.

Although the exact orientation of these veins is unknown at this point in time, they do not appear to reconcile with any known veins at the Hokuryu historic mine. Interestingly, multiple vein intercepts deeper in the hole encountered sub 1 gpt Au grades. This new vein set is believed to represent a major new discovery and is open along strike, currently thought to be roughly E-W. Irving believes that these veins, like those mined at Hokuryu, will persist to depths of several hundred meters.

True widths are believed to be approximately 70-80% of reported widths. Given the region west of Hokuryu mine site has seen no historic exploration, Irving believes there is substantial opportunity for making further discoveries of veins given the abundance of resistive features discernable in geophysical data here. More drilling is currently being contemplated to follow up these results later this year.

A second diamond drill hole at Hokuryu, 22HKR-002, terminated in broken ground well before it reached its target. 2023 Drilling at Omui Encounters Substantial Vein System at Depth: Since mid-January, Irving has been diamond drilling at the Omui Mine Site. One hole, 23OMI- 001, drilled from north to south and tested deep areas underneath the Nanko vein target where, in 2020-2021, the Company discovered an extensive high-grade vein network.

This new hole intersected multiple veins, some with visible sulfides thought to be ginguro, silver sulfosalt minerals. Notably, the deepest vein intercept occurs near 700 m vertically below surface. Assays are awaited from 23OMI-001.

A second hole, 23OMI-002, similarly drilled from north to south, is currently testing areas deep under Honpi where numerous drill holes completed between 2019-2021 encountered a complex, extensive network of high-grade veins. Notably, hole 23OMI-002 was designed to pierce through a deep level silica sinter system discovered by drilling in late 2021. Irving announced that the current hole successfully cut through the sinter starting at about 120 m and appears to have encountered a significant epithermal veins underneath.

The hole is currently at a depth of around 300 m and will progress until it is fully past this zone of veining. Once complete, this hole will be logged, split and sampled, then submitted for assay. All samples discussed in this news release are ½ split sawn diamond core samples.

Irving submitted samples to ALS Global, Vancouver, Canada, 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 (gpt) to Ag (gpt)/78. Results referred to in this news release are not necessarily representative of mineralization throughout Hokuryu.
