Drilling Commences at Irving Resources’ East Yamagano Project, Kyushu, Japan

VANCOUVER, BC / ACCESSWIRE / December 4, 2023 / Irving Resources Inc. (CSE:IRV)(OTCQX:IRVRF) ("Irving" or the "Company") is pleased to announce that diamond drilling has commenced at its East Yamagano high-grade epithermal gold-silver vein project, Kyushu, Japan. The Shin-Yamagano (New Yamagano) Prospecting Plan covering drilling activities at East Yamagano has received Ministry of Economy, Trade and Industry ("METI") Kyushu approval. Importantly, this is the first ever drill program at this large-scale target believed by Irving's geologists to potentially host the eastern extension of the famous Yamagano vein system. Yamagano was one of the largest historic gold mines in Japan. Irving plans to complete an initial one to two drill hole test over the coming months. The Company's BLYLF90D diamond drill is being utilized and is operated by Nagasaki Chiken Co. Ltd, a local drilling company sub-contracted by Irving Resources Japan GK, a wholly-owned subsidiary of Irving.

"We are delighted to undertake the first ever drill program at East Yamagano," commented Akiko Levinson, CEO and a director of Irving. "Our sincere gratitude goes out to Shimadzu Ltd, underlying owner of the core mining lease that adjoins East Yamagano and is optioned to Irving, for their assistance in helping make this happen. This drill program has great significance given the recognition of the Yamagano gold mine in Japanese history. The Yamagano district is the closest significant gold vein system to the world famous Hishikari gold mine, just eleven kilometers to the northeast with which it shares many geological similarities.[1] We hope that our drill program leads to the discovery of a deposit equally exciting as Hishikari in what we believe is the eastern extension of the Yamagano deposit."

The Yamagano project is subject to the Irving-Newmont Exploration Pty Ltd ("NEPL") and Irving-Sumitomo Corporation exploration alliance agreements. NEPL is a wholly owned subsidiary of Newmont Corporation.

Description of the Yamagano Mining License:

• The Yamagano mining district, situated approximately 11 km southwest of the large, high-grade Hishikari gold mine, is host to innumerable historic gold mine workings, some dating back to 1640AD during the early Edo Period in Japan. Mining focused on a multitude high-grade epithermal gold veins hosted by volcanic rocks blanketing this region.
• Gold veins at Yamagano appear associated with a particular geophysical feature, an area of anomalously high gravity, thought to represent a buried uplift, or dome, in underlying denser basement sedimentary rocks. Such a geologic feature is believed to have focused gold-depositing hydrothermal fluids to ascend into overlying faults and fissures where they formed extensive high-grade vein networks. A gravity high was recognized very early as an important control at the Kushikino gold mine (56 tonnes or 1.80 Moz Au produced) situated approximately 39 km southwest of Yamagano. Based upon this geologic model, initial targeting of the famous Hishikari deposits (248.2 tonnes or 7.98 Moz Au produced) was driven largely by recognition of an anomalous gravity high underlying that area. Irving believes the gravity high under East Yamagano reflects a buried dome of basement rock and that, given the large footprint of this feature, there is considerable prospectivity for a substantial vein system.
