NEWS RELEASE

Irving Resources Defines a Robust Silica-Rich Gold- and Silver-Bearing Sinter Deposit

at Omu, Hokkaido, Japan

Vancouver, British Columbia, August 24, 2023 (Accesswire) – Irving Resources Inc. (CSE:IRV; OTCQX:

IRVRF) (“Irving” or the “Company”) is pleased to announce that recent drilling at the Omu Sinter target, part

of its 100% controlled Omu Au-Ag Project, Hokkaido, Japan, has defined a robust deposit of silica with

appreciable gold and silver. Irving’s business model is to find precious metal-bearing, silica-rich rock suitable

for use as smelter flux. It believes the newly defined hot spring sinter deposit is significant, especially given that

this material starts at surface and is therefore easily accessible.

Figure 1 shows the footprint of the approximately 200m wide and 400m long silica sinter deposit. This terrace

of silica starts at surface and is open to the north. Cross sections showing gold equivalent and silica results from

drill holes are presented in figures 2-5. Silica thicknesses range from a few meters up to 54.5m. Gold values in

reported intervals range between 0.54-1.04 gpt, and silver, between 6-32 gpt. Gold equivalency ranges between

0.78-1.21gpt. Silica contents are high, commonly above 95%, making this exceptional quality for smelter flux.

Deleterious elements including arsenic, antimony and mercury, are generally low also making this material

attractive.

Importantly, by drilling this robust precious metal-bearing silica sinter deposit, the Company is confident it can

underpin a justifiable case to convert the prospecting license at Omu Sinter to a mining license, a critical step to

maintaining long term tenure over the property. Internal study of these results is progressing rapidly with the

goal of establishing such a case by early next year.

Silica-rich rock utilized for smelter flux has commercial value on the order of a few tens of dollars per tonne.

With payable precious metals, paid in the range of 90-95%, significant value is added to this material. A robust

precious metal-bearing silica deposit in Japan is viewed as having strategic value given the numerous smelters

active in the country. Irving takes the view that Omu Sinter has ideal characteristics for smelter flux and is a

potential important future source of such material.

“We are very pleased to see such continuity in grade and silica content at Omu Sinter,” commented Dr. Quinton

Hennigh, technical advisor and a director of Irving. “With low deleterious elements, this material has the

potential to be an important source of smelter flux. The current footprint of the silca body is approximately

200x400m and its average thickness is approximately 20m indicating we have a deposit of over one million

cubic meters all immediately below surface. Given our drilling from a few years ago that demonstrates there is

an underlying high-grade vein system beneath this silica, Omu Sinter is shaping up to be a potentially important

advanced-stage smelter flux deposit that could be of strategic importance to a smelter in Japan.”

All drill holes were drilled at a steep inclinations and encountered the sinter unit at nearly orthogonal orientation.

Therefore, drill intercepts are considered to be very close to true widths. 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 routinely inserts standard and blank samples in assay batches submitted to the laboratory. Company staff

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

(gpt)/78. Results referred to in this news release are not necessarily representative of mineralization throughout

Hokuryu.
