Defiance Silver Reports High-Grade Trenching
Results at San Acacio, Zacatecas
Vancouver, British Columbia--(Newsfile Corp. - November 19, 2025) - Defiance Silver Corp. (TSXV:
DEF) (FSE: D4E) (WKN: A1JQW5) ("
Defiance
" or the "
Company
") is pleased to provide an update
on the recently completed trench sampling campaign at its San Acacio property in Zacatecas, Mexico.
The company completed a large trenching program on the Veta Grande vein system across multiple
historical open pits, demonstrating strong grades and continuity at surface. The results from this
trenching program will enhance the Company's understanding of the surface geology and mineralization
and will contribute valuable data to support the upcoming mineral resource estimate. Results included in
this release were sampled along approximately 2.1km of strike length of the Veta Grande vein system,
with approximately 1.1km of trenching being completed across the vein system returning grades up to
5180 g/t Ag
and
4.85 g/t Au
(Figure 1).

This is the first significant trenching program on the project since the last historical operators removed
any notable material to mill. The purpose of the trenching program was to confirm the historical samples
and to define the scale of surface mineralization in the historical open pit operations. Additionally, the
company sought to demonstrate continuity at surface with current geochemistry and geology.
The results from this large campaign gives confidence to the near surface tonnage potential while also
demonstrating continuity between the large historical open pits (Almaden, San Jose, Esperanza,
Guadalupe). Prior to this program, limited information was available on the grade and thickness of the
vein system at surface. Trenching exposed the vein system to surface in the historical open pits as well
as exposing the vein system with trenching between the significant historical surface mining operations.
Approximately 2.1km of strike length of the Veta Grande vein system was sampled, with approximately
1.1km of trenching being done across the vein system (Figure 1).

Table 2. Sampling Summary from recently completed trenching program
Summary of Surface Trenching Program
The program consisted of ~1.1km of trenching across the main historical surface mining operations at
the San Acacio mine; the Almaden-Carolina pits, the Esperanza-Guadalupe pits and at the San Acacio
South East target.
A total of 76 trenches (from CHSA-24-01 to CHSA-24-76) were excavated and sampled in the area
known as the
Almaden-Carolina pit
. Most of the samples returned values over 60 g/t and up to 1480
Ag (Figure 2). Trench CHSA-24-32 returned
3.25m
grading 354.6 g/t Ag, 4.16 g/t Au, 4.16% Pb,
0.52% Zn
.
Excellent exposure of the Veta Grande structure occurs in the centre of the Almaden pit. It is at least 6m
wide in the exposed areas, and up to 14m wide when the unconsolidated trench debris or fill is included.
When sampled in trenches - this fill material returned an
average grade of 205.36 g/t Ag
(Table 2).
At surface, the Veta Grande system is well mineralized in silver, zinc and lead, with occasional copper
and some of the highest grades of gold found to date.

A total of 49 trenches (from CHSA-24-77 to CHSA-24-125) were excavated and sampled in the area
known as the
Esperanza-Guadalupe pits
. Most of the channel samples from the trenches returned
values over 60 g/t and up to 5180 g/t Ag (Figure 3). Channel samples from trench CHSA-24-116
returned 0.60m
5180 g/t Ag, 4.85 g/t Au, 0.74% Pb and 0.08% Zn
. This sample represents the
highest Ag sample of the trenching campaign. Another high-grade interval is within the trench CHSA-24-
110 which returned
0.85m
grading
1155 g/t Ag, 4.12 g/t Au, 2.31% Pb and 0.24% Zn
. Both samples
were collected from clast and matrix supported breccias. The trench CHSA-25-107,
4.25m
grading

A total of 28 trenches (from CHSA-25-126 to CHSA-24-153) were dug and sampled in the area known
as
San Acacio Southeast
. Most of the samples returned concentrations of less than 60 g/t Ag (Figure
4).
The trench CHSA-24-130 returned
5.85m
grading
103.9 g/t Ag, 0.94 g/t Au, 2.66% Pb and 0.01%
Zn
hosted in clast and matrix supported breccias.

Geology and Mineralization
The main mineralized structure on the Zacatecas Project is the Veta Grande vein system. The Veta
Grande vein system has a dominant northwest strike and dips towards the southwest, on average at 65
degrees. The mapped strike extent of the Veta Grande vein system within the Property is approximately
five kilometers and extends to depths of at least 400 m below surface as evidenced from underground
development and drilling on the Property. The Veta Grande vein system is characterized by three main
mineralization morphologies: fault-fill veins with polyphase breccias, vein splays with predominantly fault-
fill vein textures, and veinlet array zones that frequently display banded textures.
Mineralization at the Zacatecas Project is predominantly characterized by Ag-rich, polymetallic (Zn, Pb, ±
Au, ± Cu) intermediate sulfidation epithermal veins. These veins contain banded to brecciated textures
and show evidence of multiple hydrothermal events. Exploration work at the Project has also identified
the potential for precious metal-rich (i.e., Ag and Au) low-sulfidation epithermal veins and carbonate
replacement-style polymetallic mineralization.
Trenching Procedures
The trenches were selected based on the presence of visible mineralized veins and breccias, alteration
and geology. Different methods of excavation were used, depending on accessibility, topography and
geology. Where it was possible, a backhoe was used for excavation, and in inaccessible areas, the
trenches were excavated by hand using pick and shovel. Samples were either cut by diamond saw or
using a rock hammer and a chisel along the width of the exposed vein or host rocks. This news release
reports exclusively intact veins, breccias and rock material, although waste debris was also sampled in
some of the trenches. The waste debris was analyzed and reported in this news release, however, those
results were not utilized in any of the vein widths discussed in this news release.
The QA/QC protocol used for core sampling was adapted for channel sampling. Each trench is
referenced to a high-precision GPS control point. The length, azimuth and dip of each of the samples
were surveyed for display purposes. Plastic pick and shovels were used to collect and place the sample
material into plastic bags. Features such as mineralogy, alteration and geology were captured for each
of the samples. The last step was the shipment of samples to the laboratory for geochemical analysis.
Discussion of Quality Assurance/Quality Control (QAQC) and Analytical Procedures
QAQC for Defiance trench sampling (2024-2025): Samples were selected based on the lithology,
alteration, and mineralization characteristics; sample size averaged 3.7 kg. At least one blank, one
standard, and one duplicate were included within every 20 samples. Standard materials are certified
reference materials (CRMs) from OREAS as well as CDN standards; the suite of standards contains a
range of Ag, Au, Cu, Pb, and Zn values. Blanks and standards have been used to confirm the validity of
the analytical results.
Samples were analyzed by ALS Limited. Sample preparation was performed at their Zacatecas,
Mexico, prep facility, and analyses were performed at the Vancouver, Canada, analytical facility. All
elements except Au and Hg were analyzed by a multi-element geochemistry method utilizing a four-acid
digestion followed by ICP-MS detection [ME-MS61m]; mercury was analyzed after a separate aqua
regia digest by ICP-MS. Overlimit assays for Ag, Pb, and Zn were conducted using the OG62 method
(multi-acid digest with ICP-AES/AAS finish). Gold was measured by fire-assay with an ICP-AES finish
[50g sample, Au-ICP22].
Chris Wright, Chairman & CEO, noted:
"These results highlight the company's continued progress towards advancing a mineral resource
estimate on the Zacatecas project. The high grade, wide widths and multi hundred metre strike lengths
may also help highlight the exploration potential of many similar sized targets on the company's large
land package in the Zacatecas district."

SHARES FOR SERVICES
The Company previously entered into a non-arm's length administrative services agreement dated May
1, 2023 (the "
Agreement
"), for services provided by an officer of the Company. As part of the
consideration payable by the Company under the Agreement, the Company has agreed to issue that
number of Common Shares equal to $1,330 per month (the "
Service Shares
"), to be issued on a semi-
annual basis and pursuant to the policies of the TSX Venture Exchange (the "
TSXV
"). The Agreement
was for a term of three months and has automatically renewed in accordance with its terms, terminable
by either party providing 30 days' notice of such termination.
The deemed value of the Service Shares to be issued for a particular month, is to be the closing price of
the Company's shares on the last trading day of the month.
For services rendered under the Agreement between the period of January 1, 2025 to June 30, 2025,
the Company has issued 33,845 Common Shares at a weighted average price of $0.237 per Common

the approval of the TSXV.
The Service Shares issued are subject to a four month hold period, which will expire on a date that is
four months and one day from the date of issuance.
No new insiders will be created, nor will any change of control occur, as a result of the issuance of the
Service Shares.
As certain insiders are party to the Agreement, it may be considered a "related party transaction" under
Multilateral Instrument 61-101
Protection of Minority Security Holders In Special Transactions
("MI 61-
101") and the TSXV. The Company is relying on the exemptions from the formal valuation and the
minority shareholder approval requirements of MI-61-101 contained in section 5.5 (a) and Section 5.7
(1)(a) as the fair market value of the common shares being issued to insiders in connection with the
