Irving Resources Discovers New, Buried Hot Spring System at Omui Mine Site, Omu Au-Ag Vein Project, Hokkaido, Japan

[{"type":"text","content":" VANCOUVER, British Columbia, Dec. 13, 2021 (GLOBE NEWSWIRE) -- Irving Resources Inc. (CSE:IRV; OTCQX: IRVRF) (“Irving” or the “Company”) is pleased to announce it has discovered a new, buried hot spring system immediately beneath areas previously targeted with shallow drilling at the Omui Mine Site, part of Irving’s 100% controlled Omu Au-Ag Vein Project, Hokkaido, Japan. Also, the Company completed one diamond drill hole at Hokuryu, also part of the Omu Au-Ag Vein Project with at least one notable vein intercept. Summary of New Discovery at Omui Mine Site and Implications for Exploration Potential Hole 21OMI-002, the second diamond drill hole of a two-hole follow up drill program recently completed by Irving has encountered an approximately 100 m long intercept of beds of siliceous hot spring sinter interbedded with various clastic rocks (Figure 1) at a depth of approximately 200 vertical meters beneath the historic Honpi mine area. Textures of silica sinter include fossil algae, a common occurrence in terrestrial hot spring sinter deposits (Figure 2). Sulfide mineralization is abundant in select bands of sinter (Figure 3) suggesting this older system has potential to be associated with precious metal mineralization. The presence of this new sinter horizon suggests the presence of an older, extensive hot spring system buried underneath Honpi (Figure 4). This raises the exciting possibility that the feeder for this sinter may lie at deeper levels below Honpi. Hole 19OMI-010, a deep hole drilled by Irving in 2019, encountered numerous deep high-grade vein intercepts that might be part of the feeder system for this lower hot spring deposit. Further evidence for potential high-grade mineralization at depth comes from fragments of dark banded silica found in some Honpi vein samples. Such dark silica fragments sometimes bear abundant fine particles of electrum, a natural Au-Ag alloy, and silver sulfosalt minerals. The source of these fragments is believed to be somewhere below Honpi, but until now, a viable source could not be rationalized. It is possible that these fragments were ripped up from the lower hot spring system by hydrothermal activity and carried upward into Honpi vein where they were incorporated into later quartz veining. Other notable epithermal deposits are buried, or “blind,” including the Fruta del Norte (“FDN”) d...
