VANCOUVER, BC / ACCESS Newswire / November 11, 2026 / Irving Resources Inc. (CSE:IRV)(OTCQX:IRVRF)(FSE:1IR) (“Irving” or the “Company“) is pleased to announce that drilling has advanced within the Shimadzu Ltd.-owned Mining Right (the “Yamagano MR“) located immediately west of the East Yamagano Exploration Right, the location where the Yamagano joint venture (“Yamagano JV“) had previously been drilling.
Yamagano JV is a joint venture between Newmont Overseas Exploration Limited (“Newmont“), a wholly-owned subsidiary of Newmont Corporation, Sumitomo Corporation (“Sumitomo“) and Irving. The initial and current interests of the parties in the joint venture are Newmont, 60%, Sumitomo, 12.5%, and Irving, 27.5%.
Drilling on the Shimadzu Mining Right
In connection with the option agreement executed between Irving and Shimadzu Ltd.*, drilling within the Yamagano MR held by Shimadzu has the potential to become an added component of the Yamagano Project. The Yamagano JV operating committee decided to initiate a drilling program in mid-2026 after issuance of the required permit and other technical reviews.
The approximately 400-year history of past gold production at the closed Yamagano Gold Mine has taken place entirely within the Shimadzu-held Yamagano MR. Nearly 50 mineralized veins were identified historically within the lease area**(Fig. 1). Irving’s view is that only a limited number of these veins have been systematically developed. In the northern part of the broader Yamagano vein system, little formal mining has been conducted historically.
The first drill hole has been completed and a second hole is now in progress in the Yamagano MR (Fig. 1). Drilling of 26YY-001 (length 699.7 m; azimuth 357°; dip −45°) commenced on June 10 and was completed on September 28. Assay results are currently pending. Drilling of 26YY-002 (planned length 800 m; azimuth 175°; dip −55°) commenced on October 27.
Very little exploration drilling has historically been conducted within the Yamagano MR. These two holes target potential mineralization beneath the Post-Mineralization Hokusatsu Younger Andesite and along the eastern extension of the known mineralized veins (Fig. 2), with the aim of assessing previously unrecognized mineralization.
Drill sites were selected in light of the Yamagano Project’s exploration standards of lying on the margins of, or within areas characterized by high to moderate resistivity identified by AMT, low to moderate magnetic intensity, and elevated gravity (Fig. 3, 4, 5). To date, government approval has been obtained for up to six drill pads and eight drill holes within the Yamagano MR.

Late Miocene to Pliocene Hokusatsu Older Andesite (OA1, deep green), the oldest unit in the area, is main vein host rock and pre-mineral lithological unit.
Pliocene Nagano Formation (NA1, pale blue), lacustrine sediments covers OA1 and considered to pre- or syn mineral lithological unit.
Post mineral Early Pleistocene Hokusatsu Younger Andesite (YA1, light green) covers both OA1 and NA1 and widely distributes the Eastern extension of mineralized vein system.
