Kootenay Releases First Results from Current Drilling at

Columba

VANCOUVER, BC

,

Nov. 19, 2025

/CNW/ -

Kootenay Silver Inc.

(TSXV: KTN) (OTCQX: KOOYF)

(the "Company" or

"Kootenay")

is pleased to announce assay results from the first seven holes of the ongoing staged 50,000-meter drill

program at

Columba High Grade Silver Project

, located in

Chihuahua, Mexico

.

Drilling at the project is designed to

extend and expand known mineralization on the extensive Columba vein system, which currently hosts an inferred Mineral

Resource Estimate totaling 54.1 Moz of silver at a grade of 284 gpt (

see News Release

June 17, 2025

).

The current phase of drilling commenced in

September 2025

with five holes testing extensions of the lightly tested I Vein

trend before moving on to expand the D Vein and B Vein trends.

This release documents highlights from the first seven holes of the current program with five I Vein holes and two D Vein

holes. So far, seventeen holes are completed with ten holes still awaiting assay results. The Company is experiencing much

longer than usual wait times for results due to increased laboratory turn-around times.

Highlights of the first seven holes include:

Discovery of porphyry style gold mineralization along I Vein

hosted in breccias and feldspar porphyry in CDH-25-

217 and 218. Classic B style veins plus or minus molybdenite along with disseminated pyrite and

unidirectional

solidification textures

type veining,

a style of crystal growth,

indicative of porphyry style mineralization.

Includes

0.7 meters of 756 gpt silver 0.6% lead and 2.5% zinc.

Drilling continues with two drills as Kootenay works to expand accommodation and core storage capacity at Columba; upon

completion the Company intends to increase the number of drill rigs at the project.

Kootenay's President & CEO,

James McDonald

states,

"

Exploration at Columba continues to produce pleasant surprises. We are now seeing a gold mineralizing event with gold-

moly porphyry characteristics. The zone is strongly anomalous in gold and may indicate a different deposit type exists.

The two holes are 95 meters apart and associated with nearby magnetic highs, which may indicate the intrusive source of

the gold. More drilling will be done to assess this new target."

Dale Brittliffe VP Exploration adds,

"The anomalous gold zones we are seeing along the I Vein trend are testament to the complexity and thereby potential of

the Columba mineral camp. While we are focused on the silver rich veins to systematically extend and expand the

existing silver resource with this current drilling program, we will now also be evaluating this new and exciting gold

target."

ETWs provided for the broad anomalous gold zones in CDH-25-217 and CDH-25-218 have been estimated assuming tabular geometry parallel to the veining observed in previous drilling. This assumption is

expected to change with additional drilling information

The I Vein target tested with holes CDH-25-212, 213, 215, 217 and 218 is a northeast trending vein extending from its

intersection with the northwest trending F Vein.

The current I Vein holes are located between

250m

and

600m

northeast of the F Vein, in an area where mapping at surface

identified a weakly silver mineralized breccia known locally as "brecha negra". Of note in these holes, especially CDH-25-

217 and CDH-25-218 encountered the quartz calcite +/- barite veining with silver typical of the Columba project, but also

encountered extensive zones of anomalous gold mineralization, a characteristic not seen on other parts of the system.

The broad anomalous gold values are conspicuous in drillhole CDH-25-217 and CDH-25-218 are hosted in rhyolite breccias

and feldspar +/- quartz porphyritic intrusive rocks. These rocks display strong phyllic alteration with varying amounts of

disseminated pyrite cut by sheeted stockworking of quartz veins typical of B type veins. The veins carry very little sulfide

along with minor amounts of molybdenite. The geochemical signature of the gold mineralization is distinct from the silver

veins indicating a separate event. Additional information will be required to accurately estimate true widths represented by

these intervals.

The current phase of work comprises a planned total 50,000-meter drilling program designed to follow up on mineralized

veins comprising the Company's recent 43-101 Mineral Resource Estimate ("MRE"). The maiden MRE is detailed in a

report entitled "

Technical Report on the

Maiden Mineral Resource Estimate for the Columba Ag-Pb-Zn Project, Chihuahua

State,

Mexico

" and dated

August 1, 2025

, MRE effective date,

May 29, 2025

was filed on SEDAR+ at

www.sedarplus.ca

and is also available at the Company's website at

www.kootenaysilver.com

. Kootenay Silver is fully funded through to the

completion of the current 50,000-meter exploration drill campaign.

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 350 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.

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.

Kootenay acquired 100% of the project and has completed detailed mapping, lidar, and airborne magnetic surveys along

with over 53,000 meters of drilling in over 200 holes across various veins. The company also has a 24-year surface access

agreement that includes annual and other payments and allows for both exploration and exploitation. The agreement covers

all the mineralized areas drilled to date.

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

.
