Defiance Outlines New Targets at San Acacio Silver Project and Provides Update
DEFIANCE OUTLINES NEW TARGETS AT SAN ACACIO
SILVER PROJECT AND PROVIDES UPDATE
FOR RELEASE: MAY 29th, 2020 TSXV: DEF - OTC: DNCVF
Defiance Silver Corp. ("Defiance" or the "Company ") is pleased to announce the delineation
of multiple and significant new targets at the San Acacio silver project as well as to provide a
corporate update.
Defiance’s technical advisors, OreQuest Consultants (see News Release dated November 11 th,
2019), have spent the past 6 months executing a work program focused on property-scale
mapping, 3D modeling and drill core re -logging at the San Acacio project . As a result of this
program, OreQuest and Defiance have generated novel targets in previously overlooked
portions of the property. The recent work highlights the potential for composite vein systems
at depth and suggests the presence of a long-lived mineralizing system at San Acacio.
Significant new drill targets that have been generated include:
1) A 1.3km X 300m corridor where a hanging wall mineralizing event has been identified
(Figure 1). Key targets in this corridor include hanging wall veins parallel to the Veta
Grande and offset hanging wall structures found in the vicinity of the Tiro San Genaro.
Significant mineralization outside of the main Veta Grande structure was outlined by
positive drill results in the vicinity SAD15 -08 (Veta Natividad and Veta Grande) both at
depth and along strike between Almaden and Tiro San Genaro (Figure 2 ). Targets
include parallel and offset structures in the vicinity of previous drilling at El
Mirador/Almaden and SAD17-12/13/14.
2) Deep targets along strike of the Veta Grande to the immediate south east. This area
was tested late in 2017 and is structurally complicated, consisting of down-dropped
blocks and regional block rotation.
3) “El Mirador,” part of a multi-kilometer felsic fault structure (La Veta Morada) with visible
silver sulfides that outcrops near previous drilling in the vicinity of the Almaden Shaft
and underground workings (Figure 3). This style of structure has a positive correlation
to regional exploration and development successes at other nearby projects.

This table is presented to highlight the significant mineralization outside of the principle Veta
Grande structure. Re -logging and property- scale mapping has been successful in identifying
multiple phases or pulses of mineralization. These targets have lar gely been untested and may
have been intersected in multiple holes, such as SAD17-13, where several styles of overprinting
mineralization is witnessed at similar depths as veining found in the NW of the property in the
hanging wall of the Veta Grande structure.

& target interpretation shown in red and purple.
There is strong evidence supporting a buried system at depth. Metal zonation ratios and
alteration assemblages support this theory. More importantly, core re -logging (see Figure 4 )
identified a style of mineralization that is observed as silver sulphide veins in vertical structures
in the hanging wall of the Veta Grande, cross cutting the Veta Grande mi neralizing events.
These important observations help support the theory of a long -lived, multi -phased
mineralizing event in the Veta Grande camp. These features can be found in epithermal
environments, and micro -veining adjacent to known veins were key fea tures that led to the
blind discovery of the high-grade Martha Vein at Coeur Mining’s La Preciosa Silver Deposit.

Next Steps
1) Follow up re -logging and re -sampling of historical drill holes was initiated prior to
COVID-related shutdown and will resume as soon as the technical team can safely
return to the project in the coming months.
2) 2020 drilling, which will consist of ap proximately 5000m, is being planned with a
number of key targets existing within the current drill permit area.
3) Data compilation of all relevant historical and recent geologic and development data
from the Zacatecas District continues ; currently there is data covering over 135,000 Ha
in the database.
4) In the near -term, a property-wide surface geochemistry program will commence. This
will help identify the metal zonation and mineral system footprints. Surface
geochemistry in conjunction with geological mapping and geophysics provide excellent
tools for system fingerprinting and outlining deeper prospective targets.
5) Defiance is preparing additional drill permit applications that will test some of the
targets that lie outside of the current drill permit . Defiance will update the market on
the program when it announces the commencement of the program.
San Acacio History
Zacatecas state continues to be the top producer of silver in Mexico (INEGI Data) and is one of
the reasons Mexico continues to remain the world’s largest silver producer (CEIC Data). The
Zacatecas-Fresnillo Silver Belt is one of the most prolific silver producing areas in the world.
Production at the San Acacio mine dates to at least 1548 when Spanish colonialists mined
mainly bonanza oxide ores, typically grading in excess of 1kg/Tonne Silver. The various veins
were operated intermittently until the mid -1800’s when an English company drove the ~2km
Purisima tunnel to allow for deeper underground access and drainage. From the late 1800’s
until the Mexican Revolution in 1920, mining consisted of intermittent production from
bonanza grade ores. During the Mexican Revolution, heavy fighting in the Zacatecas region led
to the halt of most mining endeavors. In the mid 1920’s, a cyanide plant target ing silica rich
ores and a floatation plant for complex Pb -Zn ores were built with varying success until the
transition from oxide to sulphide rich ores made for recovery complexities. In the mid 1930’s
the first tonnage estimate was created on the propert y, although the project sat mostly idle
save for some stope and adit rehabilitation at Purisima and Refugio. Production was largely
dormant except for some small processing done by CIA Fresnillo in the late 1930’s to early
1940’s. In the 1960’s the Amado Mesta family built a 100 tpd floatation plant targeting dumps
and backfill material and eventually the Mesta family constructed a larger 250 tpd floatation
plant. Throughout the late 1970’ and early 1980’s a lack of camp consolidation prevented any
larger companies from acting on their interest in the Veta Grande camp. In the mid 1990’s
Silver Standard Resources Inc . began a systematic exploration and evaluation program
targeting an open pit silver mine consisting of backfill, remaining stopes and silica rich hanging
wall and footwall mineralization of the Veta Grande structure. This entry by a publicly -listed
company kicked off nearly 3 decades of exploration, development, and bulk-scale processing.
Defiance Silver has been exploring the project since 2011 and has focused primarily on
identifying near-term mine resources. Drilling by previous operators as well as Defiance Silver,
from 2009 to early 2017 confirmed the presence of significant mineralizing events that provide
evidence for a long -lived mineralizing system. Drilling in late 2017 and early 2019 outlined
complexities in the structural geology of the area and identified significant “down dropped”
and rotated structural blocks as the company tested the Veta Grande at similar elevations
where it was encountered by earlier mining and drilling. [Section Reference: Desautels 2012]
COVID-19 Response
Defiance is closely monitoring the COVID-19 pandemic, as well as the administrative order put
in place by the Federal Government of Mexico on the March 30th, 2020. As announced on May
13th, amended from the Mexican Health Ministry’s March 30th decree, the Federal Government
of Mexico has identified Mining as a n essential service. Defiance’s team continues to work
remotely on the project data for target generation, permitting and data interpretation , as well
as advancing geologic modeling . The company is anticipating a re -commencement of field
exploration activities soon while following public health directives for COVID-19.
Finally, Defiance announces that it has granted incentive stock options to certain directors
and officers to purchase up to 605,000 shares of the Company , under the terms of the
Company’s stock option plan, at an exercise price of $0.23 per share.
