NEWS RELEASE

Inomin Drilling Intersects 161.5 Metres Grading

0.19% Nickel, 0.011% Cobalt, 0.36% Chromium, and

22.7% Magnesium Starting 30 Metres from Surface

Vancouver, British Columbia, November 26, 2025 –Inomin Mines Inc. (TSX.V: MINE)(“Inomin” or the “Company”)

is pleased to announce diamond drill results from the first three holes drilled at the South zone of the Beaver-Lynx

project in south -central, British Columbia (the “Project”). Drill hole B25 -01 (Az 0, Dip -80°) intersected 161.5 metres

(m) grading, 0.19% nickel, 0.011% cobalt, 0.36% chromium, and 22.7% magnesium starting at bedrock surface

located 30 metres from surface . Drill hole B25-02 (Az 0, Dip -80°) intersected 123 metres grading 0.19% nickel,

0.011% cobalt, 0.42% chromium, and 23.9% magnesium, and drill hole B25 -03 (Az 0, Dip -80°) intersected 148

metres grading, 0.20% nickel, 0.012% cobalt, 0.38% chromium, and 21.4% magnesium. The first three drill holes

– located approximately 200 metres from drilling completed in 2023 – confirms continuity of mineralizatio n over

substantial thickness and area.

* Note: Samples were analyzed by Activation Laboratories Ltd (“Actlabs”) for a 22-element suite utilizing their 8-Peroxide (Total) Fusion, ICP-OES (FUS-

Na202). The resulting grade for nickel includes both silicate and sulphide components of nickel. A seco ndary partial digestion technique is currently

being developed by Actlabs for Inomin to ascertain the sulphide n ickel fraction only and will be utilized on all higher grading nickel values and will be

reported on when complete.

John Gomez, President of Inomin states, “These initial drilling results are excellent as we’re continuing to intersect

substantial polymetallic mineralization that is relatively uniform in grade and near-surface. The drill results also continue

to demonstrate Beaver’s potential for hosting large volumes of nickel and other critical minerals. We look forward to

receiving additional analytical results from the remaining ten drill holes including fire assay for gold on a network of

quartz veins forming a margin around the ultramafics, partial digestion results for nickel, and platinum and palladium

analyses.”

2025 Beaver-Lynx Drilling Program

The 2025 exploration program at Beaver -Lynx includes thirteen drill holes totaling 3,361.8 metres of drilling. Twelve

holes, spaced approximately 200 metres apart, were drilled in the South zone of the Project. The objective of South

zone drilling is to test continuity of known mineralization delineated by previous drilling. One hole was also drilled

in the North zone to test a new priority target to expand the North zone’s discovery footprint. Drilling at the North zone

has discovered significant mineralization on high magnetic features that extend over 7 kilometres in strike length.

The South and North zones are two of several large, mineralized zones identified by drilling and magnetic surveys at

the Beaver block of the Project. The adjoining Lynx block, 10 kilometres south of the Beaver block, hosts multiple

targets comparable and potentially larger in size than found on the Beaver block , illustrating the Project’s

district-scale potential.

Collaboration with Sumitomo

The 2025 Beaver-Lynx exploration program is being undertaken in collaboration with Sumitomo Metal Mining Canada

Ltd. (“Sumitomo”) that is funding the exploration. Sumitomo can earn an interest in the Project through an earn-in and

joint venture agreement with the Company. Inomin is the operator of the Project.

About Beaver-Lynx

The Beaver-Lynx property comprises approximately 28,000 hectares and is ideally located in south -central British

Columbia, 50 kilometres from the city of Williams Lake and adjacent to the Gibraltar mine property, the second

largest open-pit copper mine in Canada. Beaver-Lynx is easily accessible by good all -season roads, and is close to

hydro-electric power, as well as active railway lines.

Exploration, including drilling, has demonstrated the Project may host large volumes of nickel . Drilling has also

intersected cobalt, chromium, copper, silver, gold and magnesium. Given positive initial drilling and metallurgical test

results – as well as multiple, large-scale, mineral zones – the Beaver-Lynx project has the potential to be a major source

of nickel and other critical minerals . For further information about Beaver -Lynx, visit Inomin’s website
