VANCOUVER, BC, Jan. 25,
2024 /CNW/ - Kootenay Silver Inc. (TSXV: KTN)
(the "Company" or "Kootenay") is pleased to announce an
updated Mineral Resource Estimate ("MRE") on its 100% owned La
Cigarra Project ("La Cigarra"), located in the Parral Silver
District of Chihuahua State, Mexico. The current Resource Estimate,
calculated by Allan Armitage, Ph.D., P.Geo., of SGS Geological
Services in accordance with NI 43-101 standards (May 9, 2016), CIM Definition Standards
(May 19, 2014) with guidance from CIM
Best Practice Guidelines (November 29,
2019) and supersedes a 2015 mineral resource estimate, also
prepared by Dr. Armitage for previous owner Northair Silver Corp
which was acquired by Kootenay in 2016. La Cigarra is situated
within a well established Mexican mineral district and is a key
property in Kootenay's portfolio of advanced silver exploration
projects.
Highlights of the 2024 La Cigarra Mineral Resource Estimate
are as follows:
- Measured + Indicated Mineral Resources are
estimated at 15.73 Mt grading 102 g/t silver, 0.07 g/t gold, 0.16%
lead, and 0.21% zinc (120 AgEq). The Measured MRE includes
resources of 51.57 Moz of silver, 33.9 koz of gold, 54.8 Mlbs of
lead, and 73.5 Mlbs of zinc for 60.56 Moz AgEq.
- Inferred Mineral Resources are estimated at 3.37 Mt
grading 102 g/t silver, 0.06 g/t gold, 0.20% lead, and 0.19% zinc
(119 AgEq). The Inferred MRE includes resources of 11.00 Moz of
silver, 6.00 koz of gold, 14.8 Mlbs of lead, and 13.8 Mlbs of zinc
for 12.85 Moz AgEq.
- Measured+Indicated grade increases from 86 g/t to 102
g/t silver.
- Measured+Indicated ounces increase slightly from 51.47
million to 51.57 million ounces.
- Measured+Indicated tonnages decrease from 18.54 to
15.73 million tonnes (measured from 3.62 to 2.08 million tonnes and
indicated from 14.93 to 13.65 million tonnes).
- Inferred grade increases from 80 g/t to 102 g/t
silver
- Inferred tonnages decrease from 4.45 to 3.35 million
tonnes
The 2024 Mineral Resource Estimate incorporates a significantly
revised geological model compared to the previous resource and
features a database of 201 surface diamond and RC drillholes
totaling 36,988 meters and 26,419 assay intervals.
Kootenay's President & CEO, James
McDonald states, "The updated resource estimate for La
Cigarra is part of our strategy to prepare our 3 resource projects
La Cigarra, Promontorio and La Negra for advancement in a bullish
silver market while we remain focused on moving our high-grade
silver project, Columba towards an MRE.
The La Cigarra updated resource estimate is a meaningful
improvement in silver grade compared to the previous calculation,
largely due to detailed work by our team which has significantly
advanced understanding of the key mineral domains and structural
geometry of the deposit.
In the M+I category silver only grade increases from 86 gpt
to 102 gpt and contained ounces increase from 51.47 Moz to 51.57
Moz.
La Cigarra is located within 20-30 kilometres of the famous
San Francisco del Oro and Santa
Barbara deposits has significant potential for growth beyond
the limits of the new Mineral Resource. Mineralization is open
along strike to the northwest and southeast, as well as
down-dip."
The Company is unable to independently confirm or verify
the accuracy or reliability of the San Francisco del Oro and Santa
Barbara deposits. The Company also reminds investors that
the results, resources or mineralization on the adjacent properties
are not necessarily indicative of the potential for similar to
exist on La Cigarra.

The base-case AgEq
Cut-off grade of 50 g/t AgEq considers metal prices of $23.50/oz
Ag, $1,800/oz Au, $1.00/lb Pb and $1.30/lb Zn, and considers
variable metal recoveries for Ag, Au, Pb and Zn: for oxide
mineralization - 85% for Ag, 40% for Au, 75% for Pb and 65% for Zn;
for sulphide mineralization - 92% for Ag, 40% for Au, 91% for Pb
and 85% for Zn.
|
|
1AgEq = Ag ppm + (((Au ppm x Au
price/gram) + (Pb% x Pb price/t) + (Zn% x Zn price/t))/Ag
price/gram). Metal price assumptions are $23.50/oz silver,
$1,800/oz gold, $1.00/lb lead and $1.30/lb zinc.

La Cigarra Mineral Resource Estimate Notes:
- The Mineral Resource Estimate was estimated by Allan Armitage, Ph.D., P. Geo. of SGS Geological
Services and is an independent Qualified Person as defined by NI
43-101. Dr Armitage conducted a recent site visit to the La Cigarra
Property on November 28 and 29,
2023.
- The classification of the current Mineral Resource Estimate
into Measured, Indicated and Inferred mineral resources is
consistent with current 2014 CIM Definition Standards - For Mineral
Resources and Mineral Reserves. The effective date for
the Updated Mineral Resource Estimate is November 29, 2023.
- All figures are rounded to reflect the relative accuracy of
the estimate and numbers may not add due to
rounding.
- The mineral resource is presented undiluted and in situ,
constrained by continuous 3D wireframe models, and are considered
to have reasonable prospects for eventual economic
extraction.
- Mineral resources which are not mineral reserves do not have
demonstrated economic viability. An Inferred Mineral Resource has a
lower level of confidence than that applying to an Indicated
Mineral Resource and must not be converted to a Mineral Reserve. It
is reasonably expected that most Inferred Mineral Resources could
be upgraded to Indicated Mineral Resources with continued
exploration.
- The La Cigarra mineral resource estimate is based on a
validated database which includes data 201 surface diamond and RC
drill holes totalling 36,988 m. The
resource database totals 26,419 assay intervals representing
34,447 m of drilling. The average
assay sample length is 1.30
m.
- The mineral resource estimate is based on 9
three-dimensional ("3D") resource models, constructed in Leapfrog.
Grades for Ag, Au, Pb and Zn were estimated for each mineralization
domain using 1.5 metre capped composites assigned to that domain.
To generate grade within the blocks, the inverse distance squared
(ID2) interpolation method was used for all
domains. Each domain was then subdivided into oxide and
sulphide domains.
- Average density values were assigned to oxide and sulphide
domains and a waste domain based on based on a database of 1,412
samples.
- It is envisioned that the La Cigarra deposit may be mined
using open-pit mining methods. Mineral resources are reported at a
base case cut-off grade of 50 g/t AgEq. The in-pit Mineral Resource
grade blocks are quantified above the base case cut-off grade,
above the constraining pit shell, below topography and within the
constraining mineralized domains (the constraining
volumes).
- The results from the pit optimization are used solely for
the purpose of testing the "reasonable prospects for economic
extraction" by an open pit and do not represent an attempt to
estimate mineral reserves. There are no mineral reserves on the
Property. The results are used as a guide to assist in the
preparation of a Mineral Resource statement and to select an
appropriate resource reporting cut-off grade.
- The base-case AgEq Cut-off grade considers metal prices of
$23.50/oz Ag, $1,800/oz Au, $1.00/lb Pb and $1.30/lb Zn, and considers variable metal
recoveries for Ag, Au, Pb and Zn: for oxide mineralization - 85%
for Ag, 40% for Au, 75% for Pb and 65% for Zn; for sulphide
mineralization - 92% for Ag, 40% for Au, 91% for Pb and 85% for
Zn.
- The pit optimization and base case cut-off grade of 50 g/t
AgEq considers a mining cost of US$2.50/t mined, and processing, treatment,
refining, G&A and transportation cost of USD$22.40/t of mineralized material.
- The estimate of Mineral Resources may be materially affected
by environmental, permitting, legal, title, taxation,
socio-political, marketing, or other relevant issues.

The comparison table below shows the 2024 Resource estimate
compared to the previous resource. Of note Measured and Indicated
(M+I) categories include a total of 51.57 Moz of silver, a modest
increase from 51.47 Moz. The combined M+I grade, however
increased from 86.3 g/t Ag to 102 g/t Ag, (an 18% increase).
Similarly, in the Indicated category total contained silver
decreased from 11.46 Moz to 11 Moz, though overall grade
increased from 80 g/t Ag to 102 g/t Ag, (a 27% increase).
Mineralization at La Cigarra is open along both
strike directions and down-dip. The La Cigarra is a key project in
Kootenay's portfolio and is currently on care and maintenance as
the company focusses on advancing the flagship Columba Silver
Project, also in Chihuahua State, Mexico.

CAUTIONARY NOTE REGARDING
FORWARD-LOOKING STATEMENTS:
The information in this news release has been prepared as at
January 24, 2024. Certain statements
in this news release, referred to herein as "forward-looking
statements", constitute "forward-looking statements" under the
provisions of Canadian provincial securities laws. These statements
can be identified by the use of words such as "expected", "may",
"will" or similar terms.
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
subject to significant business, economic and competitive
uncertainties and contingencies. Many factors, known and unknown,
could cause actual results to be materially different from those
expressed or implied by such forward-looking statements. Readers
are cautioned not to place undue reliance on these forward-looking
statements, which speak only as of the date made. Except as
otherwise required by law, Kootenay expressly disclaims any
obligation or undertaking to release publicly any updates or
revisions to any such statements to reflect any change in
Kootenay's expectations or any change in events, conditions or
circumstances on which any such statement is based.
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.
