Kootenay Silver Provides Update on

Upcoming Mineral Resource Estimate

VANCOUVER, BC

,

May 22, 2025

/CNW/ -

Kootenay Silver Inc.

(TSXV: KTN) (OTCQX: KOOYF)

(the "Company" or "Kootenay")

pleased to announce that it is in the final stages of preparing the

maiden Mineral Resource Estimate ("MRE") for its Columba High Grade Silver Project, located in

Chihuahua, Mexico

.

The highly anticipated Columba maiden MRE includes data collected along four main vein trends, F,

D, B and J-Z. These closely linked mineralized zones represent but a portion of what is now

recognized as a silver-dominant intermediate sulfidation epithermal mineral system within an area

measuring at least 3km x 4km. The project remained untested by modern exploration methods

until Kootenay's initial drilling campaign in 2019. Initial work centered on historic underground mine

workings at the "F" Vein then quickly expanded to additional targets identified by mapping and

surface geochemistry.

Kootenay's database includes 211 diamond drill holes totaling more than 53,000 meters across

multiple high-grade vein structures and forms the basis for the forthcoming MRE. The estimation

work is being finalized in collaboration with Qualified Persons Ben Eggers, P.Geo. and

Allan

Armitage

, P.Geo. of SGS Canada Inc. The estimate is expected to be released in the coming weeks

and a site visit by the QP is scheduled for the end of May.

"

The upcoming resource estimate will be a pivotal milestone for Kootenay, representing the first

formal quantification of the high-grade silver potential we've systematically uncovered at

Columba,"

stated

James McDonald

, President and CEO.

"We're very excited to deliver this

foundational milestone to shareholders and believe it will underscore the strength of Columba as

one of the most promising new vein-hosted silver discoveries in

Mexico

."

Columba, a classic high-grade silver system situated along the famous Mexican Silver Trend is

characterized by numerous epithermal veins exposed at surface within an area measuring roughly

1,200 hectares. The upcoming MRE will provide an important benchmark for assessing the project's

scale and potential as Kootenay continues to explore the mineralized system. All structures

comprising the upcoming deposit model remain open along strike and at depth and are expected to

increase in dimension with further work. A significant follow up drilling program comprising 20,000 to

30,000 meters of extension and exploration is planned for the coming months and is expected to

culminate with sufficient data to provide an updated MRE.

Plans, maps and sections are available on Kootenay's website

results completed on the Columba Property since 2019 may be viewed here:

Kootenay acquired 100% of the project after making staged payments over a 4-year period totaling

US$3,290,000

with the final payment on

May 18, 2023

, which included

US$215,000

settled in

common shares of the Company. Per the Agreement, the vendors retained a two percent n.s.r. of

which one percent can be bought by the Company for

US$750,000

.

The Company also has a twenty four year land access agreement that allows for both exploration

and mining activities. The agreement covers the surface over all of the drilled areas and areas of

significant silver mineralization to date and includes annual payments, certain drill bonus payments

and a two percent n.s.r. of which one percent can be repurchased at any time.

Kootenay, has completed detailed mapping, prospecting, LiDAR, hyperspectral and airborne

magnetic surveys along with the 53,000 meters of drilling in over 211 holes across various veins.

About Columba Project

The Columba project is a classic high grade epithermal vein system. That management believes is a

newly recognized vein district. It is typical in character and size of other vein districts in

Mexico

known to have deposited significant resources of silver or gold such as La Chispas and

Panuco

.

Hosted within a volcanic caldera setting, the surface extent of mapped veins measures roughly 4

kilometres by 3 kilometres. Vein mineralization occurs over a minimum vertical extent of 540 meters

as shown by drilling. The veins appear to be intermediate sulfidation veins indicating the potential for

depths exceeding 700 meters of vertical extent. This remains to be tested, and all veins remain open

to depth and along strike.

The veins cut every known rock type on the project and the veins or vein structures can be traced

across the highest elevations of the caldera. This indicates veins formed late in caldera history. As

elevation increases vein development becomes irregular eventually being replaced by breccias at the

higher elevations. Silver grades diminish with increasing elevation right down to background values.

Correspondingly silver grades increase with depth from background at higher elevations to highs of

kilograms per tonne at depth. It is evident from these features that the vein system has undergone

almost no erosion and so whatever silver was deposited originally is largely still there.

A general rule of thumb on the project is at levels deeper than 1,750 meters above sea level is

where good grades begin to appear. This is what is referred to as the grade line.

Prior to Kootenay Silver no exploration had occurred at Columba in nearly 40 years. Historically

there were two periods of mining on one of the veins referred to as the F Vein. The first being in the

early 1900's when underground development included 6 drifts (tunnels) at different levels coming off

a 200-meter-deep shaft. This work was halted by the Mexican Revolution. Then a second brief

period of mining occurred around 1958 to 1960 when a small private company used the old

development to mine. It is estimated that around 100,000 tonnes were mined.

Sampling and QA/QC at Columba

All technical information for the Columba exploration program is obtained and reported under a

formal quality assurance and quality control ("QA/QC") program. Samples are taken from core cut in

half with a diamond saw under the direction of qualified geologists and engineers. Samples are then

labeled, placed in plastic bags, sealed and with interval and sample numbers recorded. Samples are

delivered by the Company to ALS Minerals ("ALS") in Chihuahua. The Company inserts blanks,

standards and duplicates at regular intervals as follows. On average a blank is inserted every 100

samples beginning at the start of sampling and again when leaving the mineral zone. Standards are

inserted when entering the potential mineralized zone and in the middle of them, on average one in

every 25 samples is a standard. Duplicates are taken in the mineralized intervals at an average 2

duplicates for each hole.

The samples are dried, crushed and pulverized with the pulps being sent airfreight for analysis by

ALS in

Vancouver, B.C.

Systematic assaying of standards, blanks and duplicates is performed for

precision and accuracy. Analysis for silver, zinc, lead and copper and related trace elements was

done by ICP four acid digestion, with gold analysis by 30-gram fire assay with an AA finish. All

drilling reported is HQ core and was completed by Globextools, S.A. de C.V. of Hermosillo,

Sonora,

Mexico
