Zacatecas Silver Announces Closing of Over-Subscribed

Financing and Outlines Path Forward

VANCOUVER, British Columbia, September 30, 2025 – Zacatecas Silver Corp. (TSXV: ZAC;

OTC: ZCTSF; Frankfurt: 7TV) (“Zacatecas” or the “Company”) is pleased to announce the closing

of its over-subscribed non-brokered private placement financing (the “Financing”) of 62,500,000

units (“Units”) at a price of $0.06 per Unit for total gross proceeds of C$3.75 million. The

Financing was previously upsized from C$2.5 million to C$3.75 million in order to include a

strategic order from a highly regarded global mining investment fund, underscoring confidence in

the Company’s high-grade silver and gold portfolio in Mexico.

Summary

• C$3.75 million private placement closed – over- subscribed and backed by a strategic

order from highly regarded mining investment fund

• 4,000-metre drill program preparation is underway to drill high-priority El Cristo and

Panuco vein systems.

• El Cristo: testing a large, underexplored vein system geologically linked to the historic

Veta Grande, which produced >200 Moz Ag historically.

• Panuco: follow-up drilling on strong high-grade intercepts and a 20.5 Moz AgEq resource

(19 Moz Ag and 19.2 Koz Au) (3.41 million tonnes at 187 grams per tonne AgEq (173 g/t

Ag and 0.18 g/t Au). See news release issued on May 30, 2023.

• Pipeline growth: Company actively reviewing new acquisition opportunities in Mexico to

further strengthen portfolio.

Eric Vanderleeuw, CEO and Director states: “This marks a pivotal step in our aggressive growth

strategy focused on unlocking the full potential of the El Cristo and Panuco vein systems —two

high-priority, high- impact targets in one of Mexico’s most prolific silver districts. Today,

Zacatecas Silver is revitalized and fully funded to aggressively advance drilling in what appears

to be the early innings of a historic metals market.”

Each Unit consists of one common share (a “Share”) and one common share purchase warrant (a

“Warrant”), with each Warrant exercisable at $0.10 per Share for a period of two years from the

date of issue (the “Expiry Date”). The Company has the right to accelerate the Expiry Date if, at

any time, the volume weighted average price of the Shares on the principal exchange or market on

which the Shares trade is equal to or greater than $0.20 for 20 consecutive trading days (“20- Day

Period”). In the event of acceleration, the Expiry Date will be accelerated to a date that is 30 days

after the Company issues the acceleration notice through a news release, provided that the

acceleration notice is issued within 10 business days after the end of the particular 20-Day Period.

Under the first tranche of the private placement, the Company paid finders fees of $117,417.33

and issued 1,962,955 non-transferable finders share purchase warrants exercisable for a period of

two years from the date of issue. The securities issued under the first tranche are subject to

restrictions on resale for a period four months from the date of issue.

The net proceeds of the Financing will be used to advance exploration activities, including drilling

at the Company’s flagship Zacatecas Silver Project, as well as for community engagement

initiatives, corporate purposes, and working capital.

Insiders subscribed for 1,000,000 Units for $60,000. This participation constitutes a “related party

transaction” as defined under Multilateral Instrument 61- 101 (“MI 61- 101”). However, the

Company expects to be exempt from formal valuation and minority shareholder approval

requirements under Sections 5.5(a) and 5.7(a) of MI 61- 101, as his participation does not exceed

25% of the Company’s market capitalization

Exploration Path Forward

• A 4,000- metre drill program is currently in preparation stages with commencement

anticipated in the coming months. Drilling will focus on high-priority targets at both the El

Cristo and Panuco North vein systems.

• At El Cristo, drilling will test a large, underexplored vein system geologically linked to

the prolific Veta Grande system, where historic mining produced over 200 million ounces

of silver.

• At Panuco, drilling follows up on strong high- grade results and the updated resource

estimate of 20.5 Moz AgEq resource (19 Moz Ag and 19.2 Koz Au) (3.41 million tonnes

at 187 grams per tonne AgEq (173 g/t Ag and 0.18 g/t Au). See news release issued on

May 30, 2023.

In addition, Zacatecas continues to actively evaluate acquisition and consolidation opportunities

in Mexico to strengthen and diversify its project pipeline.

Community Engagement and Drill Readiness

Surface access and community engagement agreements are being supported by the previously

announced engagement of Mesoamerican Explore S.A.S. de C.V. (“MES”) to provide

environmental and social services and liaise with landowners. This work is underway and

completion is expected in the coming months. Roadwork and drill pad construction are complete,

and final contractor mobilization is scheduled for late Q4 2025.

Esperanza Gold Project

Regarding the company’s Esperanza Gold Project, Eric Vanderleeuw, CEO, stated:

“Esperanza is an attrative oxide heap leach deposit, low CAPEX and high-grade, with significant

scalability. Federal permitting headwinds regarding open-pit permits had required us to pause PEA

activities and focus on keeping the project in good standing and at minimum cost - that strategy

has worked. We’ve successfully preserved the project at minimal cost, giving us optionality as the

policy environment evolves. Few undeveloped assets of this quality and size remain in the sector

and we are excited to move forward again.”

7,826 hectares (19,338 acres) of ground that is highly prospective for low -sulphidation and

intermediate-sulphidation silver base metal mineralization and potentially low-sulphidation gold-

dominant mineralization. The Company announced a n increase in silver resource at the Panuco

South and North underground Mineral Resource Estimate now consist ing of 3.41 million tonnes
