Irving Resources Encounters High-Grade Vein Intercepts and Confirms Presence of Extensive Lower Mineralized System at Omui Mine Site, Omu Au-Ag Vein Project, Hokkaido, Japan

 

 

 

 

 

Irving Resources Inc. (CSE:IRV) (OTCQX: IRVRF) is pleased to announce recent diamond drilling has encountered high-grade vein intercepts and assays confirm the presence of an extensive lower mineralized system at the Omui Mine Site, part of Irving’s 100% controlled Omu Au-Ag Vein Project, Hokkaido, Japan.

 

Summary of High-Grade Vein Intercepts and Lower Mineralized System at Omui Mine Site:

  • Significant vein intercepts from the West Honpi extension:
    • 21OMI-001:
      • 10.41gpt Au and 13.48gpt Ag (10.58 gpt Au eq) over 3.80m within
      • 7.30gpt Au and 10.15gpt Ag (7.43 gpt Au eq) over 7.05m within
      • 5.59gpt Au and 8.25gpt Ag (5.70 gpt Au eq) over 10.20m

    •  21OMI-002:
      • 15.92gpt Au and 25.50gpt Ag (16.24 gpt Au eq) over 3.95m and
      • 10.86gpt Au and 8.44gpt Ag (10.97 gpt Au eq) over 2.36m within
      • 11.19gpt Au and 15.51gpt Ag (11.38 gpt Au eq) over 8.55m within
      • 9.70gpt Au and 13.98gpt Ag (9.88 gpt Au eq) over 9.90m
  • The West Honpi intercepts presented above are situated approximately 45 m west of the collapsed workings of historic Honpi (“main vein” in Japanese) and clearly indicate this important vein is open along strike to the west as well as to depth (Figure 1 and Figure 2). True width is estimated at between 7.6m and 7.8m in this near surface location, an attractive target when considering Irving is seeking precious metal-rich silica flux material. The weighted average grade of these two intercepts, located a few meters apart, is 7.61gpt Au and 11.07gpt Ag (7.74gpt Au eq) over 7.7m.
  • As reported in the Company’s news release dated December 13, 2021, hole 21OMI-002 encountered a thick sequence of siliceous sinter interbedded with various sedimentary and volcaniclastic rocks beginning approximately 200m beneath surface (Figure 2).
  • Sinter forms when hot spring fluids rise to surface and outflow into pools or across terraces where they deposit mineral layers, in this case, of silica. Because this package of sinter occurs at depth, buried beneath a volcaniclastic layer, Irving believes the paleo-hot spring from which this sinter originates was abruptly buried while it was active. A rhyolite flow subsequently covered the area.
  • Layers of sinter in hole 21OMI-002 contain significant Au and Ag (Table 1), a strong indication this is a fertile hot spring system. Individual sample intervals assay as high as 3.55gpt Au and 565gpt Ag. Pathfinder elements including arsenic, antimony, mercury and selenium are also highly enriched in these rocks.
  • Irving believes that the structure that hosts Honpi was a feeder for this lower hot spring system, one that is capable of hosting significant high-grade Au-Ag veins. Drill testing this area is a very high priority for Irving.
  • The Company’s 2022 diamond drill campaign has recently commenced. Three holes have been designed as an immediate test of this deep system. Hole 22OMI-001, a NNE-directed hole collared approximately 360m SSW of holes 21OMI-001 and 21OMI-002 is currently at a depth of approximately 335m and has encountered multiple mineralized veins between 270m and its current depth. Ginguro, bands of silver sulfosalt minerals, is evident in several veins. Targeted depth is 700m which is about 600m beneath surface.
  • Irving believes the setting at Honpi is similar to other notable epithermal deposits that are buried, or “blind,” including the Fruta del Norte deposit in Ecuador. The buried sinter cap of the FDN system was discovered under approximately 200m of post mineral cover and the vein deposit occurs immediately beneath the sinter.

Au eq = Au + (Ag/78); Ag eq = Ag + (Au x 78); recovery of both Au and Ag is expected to be +95% as smelter flux

 

“Assays from sinter layers encountered deep in hole 21OMI-002 clearly indicate this lower mineralized system is fertile for discovery of precious metal rich veins” commented Dr. Quinton Hennigh, technical advisor and a director of Irving. “We see gold values up to 3.55gpt and silver up to 565gpt, very high for sinter deposits and a very promising sign there is substantial metal in this older system. We are very excited to once again be drilling this area. Veins are evident in core from hole 22OMI-001, some with ginguro.

 

“On top of these exciting developments, high-grade intercepts of West Honpi encountered in holes 21OMI-001 and 21OMI-002 provide further evidence that the upper mineralized system also remains very prospective for discovery of shallow precious metal-rich silica flux material. 2022 is shaping up to be a productive year for Irving.”

 

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 staff are responsible for geologic logging and sampling of core. Au equivalent is calculated by adding Au (gpt) to Ag (gpt)/78.
