Irving Resources Discovers High-Grade Feeder at Omu Sinter
Vancouver, British Columbia, June 25, 2026 (ACCESS Newswire) – Irving Resources Inc.
(CSE:IRV; OTCQX: IRVRF ; FSE: 1IR ) (“Irving” or the “ Company”) is pleased to announce
receipt of strong assay results from newly discovered feeder style mineralization at its Omu Sinter
epithermal gold-silver project located in Omu, Hokkaido, Japan. Diamond drill hole 26OMS-002,
a 53m vertical hole drilled near the eastern margin of the sinter target earlier this year, intercepted
0.98 gpt Au and 68.96 gpt Ag (2.06 gpt AuEq) over 47.7m beginning at the top of bedrock and
continuing to the end of the hole. Included within this intercept is a higher-grade subinterval
grading 4.05 gpt Au and 54.71 gpt Ag over 7.0m with a further subinterval of 10.68 gpt Au and
187.81 gpt Ag over 1.05m . Silver is notably elevated in this newly discovered zone. Results
referred to in this news release are not necessarily representative of mineralization throughout the
Omu Sinter project.
This is the first instance of such high-grade mineralization being encountered in the shallow
geologic environment at Omu Sinter. Before hole 26OMS-002, no hydrothermal feeder was
identified. Further exploration is strongly warranted in areas immediately adjacent to and below
this drill hole. The Company is in the process of filing applications for an aggressive drill program
to follow up on this important discovery.
In early 2026 , two shallow, vertical diamond drill holes, 26OMS-001 and 26OMS-002, were
completed along the eastern fringe of Omu Sinter. In addition to the strong results from hole
26OMS-002 discussed above, hole 26OMS-001 intercepted a 22.18m interval of silica sinter
grading 0.56 gpt Au and 10.36 gpt Ag (0.72 gpt AuEq). Full results from both holes are
summarized in the table below. A plan view and cross section are presented in Figures 1-3.
Table summarizing gold- and silver-bearing sinter results:
Hole From (m) To (m) Length (m) Au (gpt) Ag (gpt) AuEq (gpt) SiO2 (%)
26OMS-001 5.38 27.56 22.18 0.56 10.36 0.72 97.6
including 8.00 9.40 1.40 1.05 27.40 1.48 98.0
and 13.00 17.00 4.00 1.10 21.45 1.44 98.4
26OMS-002 5.30 53.00 47.70 0.98 68.96 2.06 91.7
including 6.00 13.00 7.00 4.05 54.71 4.90 83.7
including 11.00 12.05 1.05 10.68 187.81 13.61 80.7
including 37.00 53.00 16.00 0.40 121.00 2.24 93.4
This hole ended in mineralization with the last meter assaying 0.44 gpt Au and 109.00 gpt Ag
AuEq = Au + (Ag/64); recovery of both Au and Ag is expected to be +95% as smelter flux; true width of this newly discovered feeder zone
cannot be established without further data
Silica contents from the 22.18m intercept in hole 26OMS-001 are high, and in line with other
nearby intercepts of silica sinter. In hole 26OMS-002, silica contents are modestly lower, a
reflection of the fact that mineralization is comprised of a network of silica veins and breccias
hosted by a variety of volcanic and siliciclastic rocks. In other words, the elemental components
of these other rock types slightly dilute their silica contents.

Additional drilling is ongoing at Omu Sinter conducted by Irving under the direction of earn-in
partner, JX Advanced Metals Corporation (“ JX”). JX Advanced Metals Corporation (“ JX”) is
funding drilling as part of its three-year option agreement outlined in the Company’s news release
dated November 13, 2024, whereby JX may earn a 75% interest at Omu Sinter Pit (covering 1.962
square kilometres) to a depth of approximately 50 metres below sea level and is in the process of
collecting sufficient technical data to determine if the deposit can make a suitable source of silica
flux for the Japanese smelting industry.
“Assays from 26OMS-002 confirm our early suspicion that we have discovered the hydrothermal
feeder for Omu Sinter along its eastern margin,” commented Dr. Quinton Hennigh, technical
advisor and a director of Irving. “Finding high-grade precious metals in the shallow environment
is a first, and we think this bodes well for the discovery of a more substantial deposit at depth. It
is within the boiling zone in epithermal systems that bonanza grades can occur. That typically lies
at a few hundred metres depth. Given that we now have clear sight on the structural feeder, we
plan to test the deeper part of this zone with aggressive drilling starting later this year. We are
thrilled to see this story unfold like it is.”
All samples discussed in this news release are ½ split sawn diamond core samples. Company staff
are responsible for geologic logging and sampling of core. Irving staff submitted samples to ALS
Global, Perth, Australia, 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. SiO2 (silica) percentage was
calculated by XRF (Xray Fluorescence) following a lithium borate fusion with the addition of
strong oxidising agents to decompose sulphide-rich ores. Irving routinely inserts standard and
blank samples in assay batches submitted to the laboratory. Au equivalent is calculated by adding
Au (gpt) to Ag (gpt)/64.
Quinton Hennigh (Ph.D., P.Geo.) is the qualified person pursuant to National Instrument 43-
101 Standards of Disclosure for Mineral Projects responsible for, and having reviewed and
approved, the technical information contained in this news release. Dr. Hennigh is a technical
advisor and a director of Irving and has verified the data disclosed including sampling, through
review of photographs of core prior to and after sawing and sampling, and analytical, through
review of standard and blank analyses.
