Defiance Silver San Acacio Drilling Returns
High Grade Silver; Additional Holes Pending
from Lucita Drilling
Vancouver, British Columbia--(Newsfile Corp. - September 9, 2026) - Defiance Silver Corp. (TSXV:
DEF) (FSE: D4E) (WKN: A1JQW5) ("
Defiance
" or the "Company") is pleased to provide the results on
the drilling campaign on the San Acacio resource drilling program on the Zacatecas project. The
campaign was designed to confirm the extension of the known mineralized structures both laterally and
vertically as well as to validate the current geological model that will be used for the upcoming Mineral
Resource Estimate. This release contains results from holes: DDSA-26-89 through DDSA-26-92.
The drilling campaign has successfully completed 6,132m distributed in 21 holes in the resource area.
The samples from holes DDSA-26-89 to DDSA-26-92 are reported in this release. The company is
looking forward to integrating the assay results from the San Acacio drilling into the Mineral Resource
Estimate, which is currently underway. The remaining 4,064 meters were used to test highly prospective
targets in the Lucita South area, including a significant test of the high-grade multi-kilometre long
Palenque vein system. The Lucita project forms part of the 4,217 Ha, Zacatecas Project. Defiance has
released previous grassroots discovery results in NR dated
August 9, 2022

Discussion of Results
DDSA-26-89
Drilling was carried out in the central block, near its boundary and between drill holes
SAD95-12 and SAD95-34, about 40 m below the surface. The purpose was to determine continuity in
the gap between the historical Almaden and Esperanza open pit mines. Drilling was also designed to
test east-west features identified in surface mapping and confirm the results from the 1995 drilling. It also
aimed to improve understanding of how the geological features are arranged. The Veta Grande was
expected at about 40 m and was found near the surface well preserved but strongly oxidized. Narrow
zones with high mineral concentrations were also found in the hanging wall of the Veta Grande vein
system.
DDSA-26-90
Drilling was carried out in the central block, near its boundary and above the San Genaro
fault system. The Veta Grande was found across a wide interval, with high zinc values but less silver than
expected. Several narrow zones with high silver concentrations were also encountered in the hanging
wall of the vein system.
DDSA-26-91
Drilling was carried out in the northwestern block, near the concession boundary. The
design of this hole was planned to follow up on the small veins and veinlet array zones with high mineral
concentrations, as encountered in drill hole DDSA-23-64, as reported in the NR dated
June 7, 2023
,
which encountered two significant zones of appreciable silver grade: 4.80m of 349.37g/t Ag (from
236.72m to 241.52m) including 1.32m of 1,264.42 g/t Ag (from 239.07m to 240.39m) and 3.21m of
200.05 g/t Ag (from 256.22m to 259.43m). Drilling was stopped because the hole deviated significantly
from the planned target pierce point.
DDSA-26-91A and DDSA-26-92
These holes were drilled in the northwestern block, near the
concession boundary. Their purpose was to continue investigating the small veins and zones with high
mineral concentrations as encountered in drill hole DDSA-23-64. The final drill hole of this campaign at
San Acacio was DDSA-26-92. Drilling was successful in identifying a wide zone containing gold and
base metals. This zone includes small veins in the hanging wall of the Veta Grande as well as the Veta
Grande itself.

Discussion of QA/QC and Analytical Procedure
Samples were selected based on the lithology, alteration, and mineralization characteristics; sample
size ranges from 0.25 - 2m in width.
All altered and mineralized intervals were sent for assay. One blank,
one standard, and one duplicate were included within every 20 samples. Standard materials are
certified reference materials [CRMs] from OREAS and CDN that contain a range of Ag, Au, Cu, Pb, and
Zn values. Blanks, standards, and duplicates did not detect any issues with the analytical results.
Samples were analyzed by ALS Chemex Laboratories, an independent analytical facility. Sample
preparation was performed at the 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].
