Zacatecas Silver Launches 4,000-Metre Drill Program with Aggressive Focus on El Cristo Vein
System and Regional Growth Strategy
Announces Private Placement Financing of up to $2.5 Million
Vancouver, BC – August 13, 2025 – Zacatecas Silver Corp. (TSXV: ZAC; OTC: ZCTSF; 7TV: Frankfurt)
(the “Company”) is pleased to announce the launch of a 4,000 -metre diamond drill program at
its wholly owned Zacatecas Silver Project in Mexico. The campaign will focus on advancing the
high-priority El Cristo and Panuco North vein systems. Designed to b uild on recent structural
reinterpretations and the Company’s foundational NI 43 -101 resource at Panuco, the program
aims to unlock what could be a significantly larger silver system within one of Mexico’s most
prolific mining districts.
• 4,000-metre drill program underway at high -priority El Cristo and Panuco targets in
Zacatecas, Mexico.
• El Cristo to test large, underexplored vein system linked to historic Veta Grande.
• Strong high -grade results and updated 20.5 Moz AgEq resource at Panuco support
further exploration (see news release dated May 30, 2023 and additional information
below).
• $2.5M private placement to fund drilling, community work, and strategic growth.
• Actively reviewing new acquisition opportunities to strengthen the project portfolio.
El Cristo: A Major Push into an Untested, High-Potential System
The Company has finalized the design of a 2,500-metre diamond drill program at its wholly owned
El Cristo Silver Project and is in the final stages of preparation for drill mobilization, targeted for
December 2025. Major Drilling (Mexico) (TSX: MDI), which previously drilled successfully at El
Cristo, is the world’s leading provider of specialized drilling services in the metals and mining
industry and has been engaged for the program. The Company is currently finalizing the terms of
the drill contract for targeted commencement in Q4.
To support ongoing environmental and community initiatives, the Company has re -engaged
Señor Emilio Torres through his consultancy, Mesoamerican Explore S.A.S. de C.V. (“MES”), to
provide environmental and social services and liaise with landowners. Señor Torres has
successfully negotiated access for all previous exploration campaigns at Zacatecas Silver’s
projects and is highly respected among local communities.
The El Cristo vein system is interpreted as the northwestern extension of the prolific Veta Grande
vein, which has reported - though unverified - historical production of over 200 million ounces of
silver. The El Cristo system exhibits similar structural characteristics, vein orientation, and
geological setting as Veta Grande, featuring a sigmoidal zone of dilation extending over 3
kilometres along strike and up to 600 metres in width. Multiple steep ly dipping, northwest -
southeast trending veins have been historically mined via at least 20 near -surface shafts and
numerous surface workings.
El Cristo hosts an intermediate sulphidation, silver -dominant lead -zinc base metal system,
characterized by steeply dipping quartz -carbonate-sulphide veins. Globally and within the
Zacatecas region, such deposits can host economic mineralization over vertical extents exceeding
600 metres - making them particularly attractive exploration targets.
Previously, the Company completed 28 diamond drill holes totaling 2,815 metres at El Cristo,
primarily targeting near-surface extensions of veins proximal to historical workings and areas of
anomalous surface geochemistry. Notably, 22 of the 28 holes intersected silver and base metal
mineralization. Key intercepts include:
• 9.00 m @ 158 g/t AgEq (149 g/t Ag, 0.05 g/t Au, 0.08% Zn, 0.05% Pb) from 17.87 m (CRI -
2022-018)
• 0.82 m @ 592 g/t AgEq (84 g/t Ag, 0.14 g/t Au, 3.7% Zn, 11.8% Pb) from 69.10 m (CRI -
2022-020)
• 3.00 m @ 262 g/t AgEq (250 g/t Ag, 0.07 g/t Au, 0.1% Zn, 0.04% Pb) from 21.00 m (CRI -
2022-026)
• 2.10 m @ 204 g/t AgEq (200 g/t Ag, 0.03 g/t Au, 0.03% Zn, 0.01% Pb) from 47.14 m (CRI -
2022-017)
• 1.60 m @ 181 g/t AgEq (175 g/t Ag, 0.02 g/t Au, 0.06% Zn, 0.05% Pb) from 4.40 m (CRI -
2022-027)
* See news release dated August 29, 2022 for additional information. Assumptions used in USD
for the silver equivalent calculation were metal prices of $24/oz silver, $1,800/oz gold, $1.81/lb
zinc, $ 0.90/lb lead. Metallurgical recoveries have been estimated to be 85% silver and 90%
gold.
Most of these intercepts were within 50 metres of surface, in highly oxidized and leached
material. The deeper sulphidic mineralization underlying these intercepts remains untested —
representing high-reward targets for the upcoming campaign. In addition, undrilled sections of
veins with a cumulative strike of over 3 kilometres offer robust, drill -ready targets beneath
surficial workings and geochemical anomalies. Several of these will be tested with shallow, angled
holes.
“El Cristo has the scale, structure, and signature of a significant system - and we’re going after
it,” said Eric Vanderleeuw, CEO. “El Cristo is a western extension of the prolific Veta Grande vein
system and so far has carried very good grade , and we believe the deeper, untested sulphide
zones could be game-changing.”
Panuco: Advancing a Proven High-Grade System
Concurrent with El Cristo drilling, the Company will revisit Panuco for up to 1,500 metres of
drilling, where extensive prior work has returned high-grade intercepts, including:
• 1.25 metres at 1,440 g/t silver equivalent (1,423 g/t silver and 0.23 g/t gold)
• 1.23 metres at 750 g/t silver equivalent (723 g/t silver and 0.36 g/t gold)
* See news release dated April 7, 2022 for additional information. Assumptions used in USD for
the silver equivalent calculation were metal prices of $24/oz silver, $1,800/oz gold.
Metallurgical recoveries have been estimated to be 85% silver and 90% gold.
On May 30, 2023, Zacatecas Silver published an updated resource estimate at Panuco:
• Panuco South Deposit Inferred Mineral Resource of 3.04 million tonnes at 179 g/t AgEq
for 17.5 million ounces AgEq.
• Panuco North Deposit Inferred Mineral Resource of 0.37 million tonnes at 255 g/t AgEq
for 3.0 million ounces AgEq
The Panuco South and North underground Mineral Resource Estimate now consists of 3.41
million tonnes at 187 g/t AgEq (173 g/t Ag and 0.18 g/t Au) for 20.5 million ounces AgEq (19.0
million ounces silver and 19.2 thousand ounces gold).
New 3D modeling and structural reinterpretation have opened up new exploration opportunities
along strike and at depth.
“Our updated structural models show compelling opportunities to extend known
mineralization,” said Dr. Chris Wilson, Chief Geologist. “This next round of drilling is designed to
expand on that base —but El Cristo offers a scale and upside near surface that we’re especially
excited about.”
Community Engagement and Drill Readiness
Surface access and community engagement agreements are being supported by the engagement
of MES and are nearing completion. Roadwork and drill pad construction are complete, and final
contractor mobilization is scheduled for early Q4 2025.
Aggressive Growth Strategy and Upcoming Catalysts
This 4,000 -metre program represents Phase I of a broader multi -stage exploration initiative
planned through 2025. The Company is also actively evaluating strategic acquisition
opportunities in the region with a focus on advanced, but under-explored, high-grade gold, silver
and copper projects.
“With silver prices strengthening and regional activity heating up, we’re entering a new phase of
the Company’s growth,” added Eric Vanderleeuw . “We’re fully committed to advancing our
existing assets while aggressively and strategically expanding our portfolio. We hope to update
our investors on this direction in the near future.”
