Irving Resources Hits More High-Grade Veins at Omui Mine Site

VANCOUVER, British Columbia, Aug. 13, 2020 (GLOBE NEWSWIRE) — Irving Resources Inc. (CSE:IRV) (“Irving” or the “Company”) is pleased to announce assay results from multiple high-grade epithermal veins encountered in recent diamond drilling at Omui Mine Site, part of its 100% controlled Omu Gold Project, Hokkaido, Japan.


  • Assays from diamond drill holes 20OMI-002 and 20OMI-003, the first holes Irving has completed at its Nanko target, confirm the presence of multiple gold-silver veins (please refer to the table below). Results include 12.59 gpt Au and 91.36 gpt Ag (13.81 gpt Au eq) over 2.01 m within 2.90 gpt Au and 29.5 gpt Ag (3.29 gpt Au eq) over 14.50 m in hole 20OMI-002. Hole 20OMI-003 yield one vein intercept of 8.15 gpt Au and 147.29 gpt Ag (10.11 gpt Au eq) over 1.76 m within 3.55 gpt Au and 69.24 gpt Ag (4.47 gpt Au eq) over 14.24 m and a second of 21.65 gpt Au and 538.75 gpt Ag (28.83 gpt Au eq) over 1.72 m including 56.10 gpt Au and 1,435.00 gpt Ag (75.23 gpt Au eq) over 0.60 m (please refer to Figure 1 for drill hole location and Figures 2 and 3 for cross sections).

  • Holes 20OMI-002 (south oriented at -60 degrees) and 20OMI-003 (north-northeast oriented at -60 degrees) are the first ever drill holes completed at Irving’s Nanko target situated approximately 600 m south-southeast of the Honpi area drilled late last season and earlier this year (please refer to  the Company’s news release dated June 25, 2020 for further information). The two holes, situated approximately 200 m apart clearly indicate a strong mineralizing system is present in this area.
  • Multiple vein phases have been documented through logging, some visibly mineralized with ginguro, silver sulfosalts, and others with no apparent ginguro. Core orientation data indicates at least two primary orientations of mineralized veining, one oriented east-southeast and another oriented northeast, both dipping steeply. At this time, Irving cannot firmly establish true thickness of these veins. Further drilling is needed to gain a better understanding.
  • Notable long intervals of mineralization were encountered in the upper parts of both holes in a regime Irving believes is within the base of the siliceous sinter cap of the hot spring system. These intervals include 2.90 gpt Au and 29.50 gpt Ag (3.29 gpt Au eq) over 14.50 m beginning at 74.7 m in hole 20OMI-002 and 1.71 gpt Au and 21.64 gpt Ag (2.00 gpt Au eq) over 14.60 m beginning at 41.30 m in hole 20OMI-003. These mineralized intercepts include siliceous breccias that appear to have formed during intense hydrothermal explosions. Further drilling is needed to ascertain whether this mineralization potentially forms a blanket like deposit in this area or if it represents the upper expression of deeper vein system below.
  • Hole 20OMI-003 encountered an impressive vein intercept of 3.55 gpt Au and 69.24 gpt Ag (4.47 gpt Au eq) over 14.24 m including 8.15 gpt Au and 147.29 gpt Ag (10.11 gpt Au eq) over 1.76 m beginning at 207.00 m down hole. A second narrower, but higher grade vein grading 21.65 gpt Au and 538.75 gpt Ag (28.83 gpt Au eq) over 1.72 m including 56.10 gpt Au and 1,435.00 gpt Ag (75.23 gpt Au eq) over 0.60 m was encountered at a down hole depth of 341.7 m. Irving believes this deeper vein intercept is a splay, splinter structure, off the much larger vein intersected higher in the hole. Therefore, Irving believes there is good potential to find higher grades within the larger vein at deeper levels that are within the boiling level of the system. Further drilling will be required to test this possibility.
  • Irving has recently completed holes 20OMI-004 (north-northeast oriented at -55 degrees) and 20OMI-005 (north-northeast oriented at -65 degrees) above and below hole 20OMI-003, respectively. Veins and other styles of mineralization similar to that observed in hole 20OMI-003 were observed in both holes. Core has been sawn and samples shipped for assay.
  • Irving is currently drilling hole 20OMI-006 (south-southwest oriented at -60 degrees), collared approximately 50 m north of hole 20OMI-002 which aims to undercut the veins encountered in that hole.

“We now have solid confirmation a significant precious metal vein system underlies the Nanko target,” commented Dr. Quinton Hennigh, director and technical advisor to Irving Resources. “We are very please to see solid assys from multiple veins in holes 20OMI-002 and 20OMI-003, the first two holes drilled here. Interestingly, we see preservation of the entire profile of the hotspring system here much like at Omu Sinter. That means we have some near surface mineralization associated with the sinter cap as well as some high-grade veins below. To gain a better understanding of this robust mineralizing system, our plan is to drill several more holes here before the end of the Omui Mine Site program later this year.”

The Omu region continues to report no cases of COVID-19, and Irving continues to operate under strict Company guidelines.

All samples discussed in this news release are ½ split sawn diamond core samples. Irving submitted rock 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 staff are responsible for geologic logging and sampling of core. Au equivalent is calculated by adding Au (gpt) to Ag (gpt)/75.
