Defiance Reports High Grade Drill Results at San Acacio
Defiance Reports High Grade Drill Results at
San Acacio
Vancouver, British Columbia--(Newsfile Corp. - February 20, 2026) - Defiance Silver Corp. (TSXV:
DEF) (FSE: D4E) (WKN: A1JQW5) ("
Defiance
" or the "
Company
") is pleased to provide an update on
the current drilling campaign at 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. The company continues
to consistently encounter high grade silver mineralization in multiple mineralized zones with lateral and
vertical continuity in the Veta Grande system. This release contains results from five holes: DDSA-25-73
through DDSA-25-77, representing 2,553m of the 10,000m diamond drill program that began
Sept 12,
2025
. The company has completed 12 drill holes to date and additional drill holes will be reported as the
company receives the analytical results.

Discussion of Results
Defiance announced the start of the drill program on
September 12, 2025 NR
. The information
presented in this release includes approximate 2,553 metres of drilling of a minimum 10,000m drill
program designed to collect additional data in the San Acacio proposed mineral resource area. These
holes were designed to improve the main Veta Grande structural model and to infill poorly drilled zones,
as well as to test both mineralized hanging wall and footwall splays to the Veta Grande system.
High
grade results over wide widths were encountered in Holes DDSA-25-75, 25-76 and 25-77.
Through surface mapping and drilling, the company has been able to identify at least three blocks on the
main Veta Grande structure, these blocks are delineated by major N-NW striking faults, where
displacement of the veins, mineralization styles and vein splays occur. The displacement of the vein in
the area of the upcoming mineral resource estimate, can be approximately 15m to 30m.
The current blocks are being delineated by the San José and San Genaro Fault systems and are named
as follows: NW block, Central block and SE block. NW block includes significant past producing
Carolina and Almaden Pits. The Central block includes the past producing Esperanza pit and part of
Guadalupe Pits, one of the largest past producing open pits at San Acacio. The SE block is part of
Guadalupe to Refugio-Tiro Intermedio area.
DDSA-25-73: Re-entered historical drill hole SAD-17-29, an older drill hole that ended before reaching
the Veta Grande structure; by re-entering, the company was able to prove the continuity of the Veta
Grande structure on the SE block. Although the Veta Grande structure was intercepted and some silver
values were detected, the hole returned no results >100ppm Ag.
DDSA-25-74: Re-entered DDSA-21-48 The Veta Grande structure was intercepted and some silver
values were detected; the hole returned no results >100ppm Ag.
DDSA-25-75: The first objective was to better define the width of Veta Navidad and further down hole,
drill through high grade veinlets arrangements and then intersect the Veta Grande. The intercept of Veta
Navidad in this drill hole, which was designed to cut through the vein perpendicularly, is only 0.8m, which
confirms that it is indeed a narrow subvertical structure. The hole was successful in identifying high grade
veinlet arrays between the Veta Navidad and the Veta Grande.
DDSA-25-76: Infill drill hole that 76 targeted the intersection of Veta Grande with hanging wall splays that
create a mineralized shoot below the past-producing Esperanza Pit area that is coherent with a wide
mineralized vein at surface. The highest values correspond to one of the modelled mineralized splays in
Veta Grande vein system.
DDSA-25-77: Re-entered historical drill hole SAD-17-30A which previously encountered drilling
problems and did not intercept Veta Grande when it was drilled in 2017. This drill hole targeted SE block
hanging wall splays and the Veta Grande. Hole 77 was successful in intercepting the Veta Grande but
with low grades. The wide intercepts with high grades correspond to widely mineralized veinlet zones
both in both the hanging wall and footwall of the Veta Grande. The company believe that these wide,
mineralized, array zones have the potential to add ounces to the upcoming resource estimate.

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].
