# Kootenay Silver Commences 3D-IP and AMT Geophysical Survey at the Columba Silver Project, Chihuahua, Mexico
February 25, 2026
Kootenay Silver Commences 3D-IP and AMT Geophysical Survey at the Columba Silver
Project, Chihuahua, Mexico
Kootenay Silver Inc. (TSXV: KTN; OTCQX: KOOYF) (the "Company" or "Kootenay") is
pleased to announce a comprehensive three-dimensional induced polarization (“3D-IP”) and
Audio-Magnetotelluric (“AMT”) geophysical survey is underway at its Columba Silver Project,
located in Chihuahua State, Mexico. The survey will test over 1,250 hectares and is expected to
take approximately 8 weeks to complete.
Previous drilling has successfully delineated near-surface and intermediate-depth silver zones,
culminating in the project’s maiden inferred category Mineral Resource Estimate (“MRE”) of
54.1 Moz silver within 5.92Mt at a grade of 284 gpt silver. The inferred resource also contains
25.2Mlb lead and 65.6Mlb zinc at grades of 0.19% lead and 0.50% zinc. (The technical 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, filed on SEDAR+ at www.sedarplus.ca and is also available at the Company’s website
at www.kootenaysilver.com.
The Company believes that, combined with the extensive geologic knowledge gained from over
235 drill holes, the ground geophysics will provide valuable insights to aid in the discovery of
additional concealed mineralization at Columba; both along existing structures like the D Vein
and in areas not yet tested by drilling.
SJ Geophysics Ltd, of Delta B.C., is conducting the work planned on 100-meter spaced lines, with
individual lines ranging from approximately 2.6 to 4.0 kilometers in length. Data will be acquired
using a diamond-mesh array configuration designed to image chargeability and resistivity contrasts
associated with sulphide mineralization, providing a robust depth of investigation exceeding one
kilometer depending on subsurface resistivity conditions.
In conjunction with the 3D-IP survey, AMT data will be collected during 3D-IP transmitter off-
times using high-sensitivity induction magnetometers and the same electric dipole array. The
AMT component is expected to provide complementary deep resistivity information, enhancing
the Company’s ability to map major structures, alteration zones, and potential feeder systems
beneath and beyond the limits of existing drilling.
The integrated 3D-IP and AMT datasets will be processed and inverted into three-dimensional
resistivity and chargeability models, which will be used to refine drill targeting and guide future
exploration programs at Columba. The Company believes this survey represents an important step
toward identifying additional high-grade silver targets and evaluating the broader scale potential
of the project.
The company’s VP Exploration, Mr. Dale Brittliffe, states “Drilling to date has been extremely
successful and we are systematically progressing along the mineralized structures at 100 meter
spacings. The additional information to be gained by the new 3D-IP and AMT survey will help us
interpret the complex geological relationships we see at depth. The work is expected to help vector
into zones of highest potential along existing mineralized structures and also additional hotspots
on the as-yet undrilled veins mapped at Columba.”
Kootenay Silver continues to advance the Columba Project as a core silver exploration asset and
is currently drilling with two diamond drills and is about 15,000 meters into its current 50,000
meter drilling program of extension and exploration. Additionally, the recently closed financing
allows for another 10,000 meters of budgeted drilling beyond the current 50,000 meter program.
Furthermore, we would like to clarify that we have changed the measured and indicated silver
equivalent and inferred silver equivalent ounces on our website and corporate presentation as the
prior calculation excluded the lead and zinc contained in the La Cigarra deposit. The result
increases the M+I category by approximately 4% and increases the inferred category by just under
2%.

Forward-looking statements are necessarily based upon a number of factors and assumptions
that, while considered reasonable by Kootenay as of the date of such statements, are inherently

Cautionary Note to US Investors: This news release includes Mineral Reserves and Mineral
Resources classification terms that comply with reporting standards in Canada and the Mineral
Reserves and the Mineral Resources estimates are made in accordance with National Instrument
43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). NI 43-101 is a rule
developed by the Canadian Securities Administrators that establishes standards for all public
disclosure an issuer makes of scientific and technical information concerning mineral projects.
These standards differ significantly from the requirements adopted by the U.S. Securities and
Exchange Commission (the “SEC”). The SEC sets rules that are applicable to domestic United
States reporting companies. Consequently, Mineral Reserves and Mineral Resources information
included in this news release is not comparable to similar information that would generally be
disclosed by domestic U.S. reporting companies subject to the reporting and disclosure
requirements of the SEC. Accordingly, information concerning mineral deposits set forth herein
may not be comparable with information made public by companies that report in accordance
with U.S. standards.
