Zacatecas Silver Reports its Initial Inferred Mineral Resource Estimate of

16.4 Million Silver Equivalent Ounces at 187 g/t AgEq at the Panuco Deposit

Including a Zone of 5.1 Million Silver Equivalent Ounces at 235.25 AgEq

VANCOUVER, BC

,

Dec. 14, 2021

/CNW/ - Zacatecas Silver Corp. ("Zacatecas Silver" or the "Company") (TSXV: ZAC) (OTC Markets: ZCTSF) (

Frankfurt

: 7TV)

is pleased to announce its initial silver Mineral Resource Estimate at the Panuco Deposit within the Zacatecas Property. The Mineral Resource Estimate was

prepared by P&E Mining Consultants Inc. ("P&E") for Zacatecas Silver.

Highlights:

Panuco Central Vein contains an Inferred Mineral Resource of 2.1 million tonnes at 171 g/t AgEq for 11.3 million ounces AgEq.

High-grade Panuco North Vein contains an Inferred Mineral Resource of 0.7 million tonnes at 235 g/t AgEq for 5.1 million ounces AgEq.

Zacatecas

actively drilling Panuco Deposit targeting expansion along strike and at depth

Multiple recently announced drill results (including intercept returning

2.17m

at 823 g/t AgEq on

November 23, 2021

) are not included in this

Mineral Resource calculation and were generated outside the dimensions of the historical Mineral Resource

The Panuco Deposit Mineral Resource Estimate consists of

2.7 million tonnes at 187 g/t AgEq (171 g/t Ag and 0.17 g/t Au) for 16.4 million ounces AgEq (15

million ounces silver and 15 thousand ounces gold) that is comprised of:

The Panuco Central Vein that contains an Inferred Mineral Resource of 2.1 million tonnes at 171 g/t AgEq (156 g/t silver and 0.16 g/t gold) for 11.3

million ounces AgEq (10.3 million ounces silver and 11 thousand ounces gold), and

Panuco North Vein which contains an Inferred Mineral Resource of 0.7 million tonnes at 235 g/t AgEq (216 g/t Ag and 0.21 g/t Au) for 5.1 million

ounces AgEq (4.7 million ounces silver and 5 thousand ounces gold).

See Table 1 on the breakdown of metal components that comprise the AgEq

disclosure.

Dr.

Chris Wilson

, Chief Operating Officer and a Director of

Zacatecas

comments, "

This Mineral Resource Estimate of over 16 million silver equivalent ounces

is a great foundation for Zacatecas Silver. Our experienced field team will continue to focus on Mineral Resource expansion drilling at

Panuco

, along strike and

at depth, while also carrying out pure exploration drilling at newly identified regional targets within the large land package

. Drilling is currently focused on the

Tres Cruces

vein to the north of

Panuco

where where the results from the first four diamond drill holes returned results of up to

2.17m

at 823 g/t AgEq (as

outlined in a

23 November 2021

News Release)."

Notes:

(1)

Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability.

(2)

The estimate of Mineral Resources may be materially affected by environmental permitting, legal title, taxation, socio-political, marketing or other relevant issues.

(3)

Resources are classified according to Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards (2014) and CIM Best Practices (2019);

(4)

The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an

Indicated Mineral Resource with continued exploration.

(5)

Silver equivalent Mineral Resources for the Panuco Deposit were calculated using the following metal prices: Ag at US $21/oz and Au at US$1,625/oz.

(6)

Metallurgical recoveries have been estimated to be 82% silver and 95% gold.

(7)

The Inferred Mineral Resource Estimate uses a cut-off of 100 g/t AgEq based on US$/tonne costs of $35/mining, $15 processing and $5 G&A.

(8)

AgEq = Ag g/t + (Au g/t x 90)

Zacatecas Silver CEO and Director, Bryan Slusarchuk, notes

"This is the first Mineral Resource published by Zacatecas Silver and we are very pleased with the

results. While a great start, our technical team believes there is significant potential to expand this Mineral Resource along strike and at depth while also

targeting new discoveries on previously under drilled and undrilled exploration targets within the large land package. One thing important to note about the

Mineral Resource described today is that a very substantial component is comprised of silver, with a small gold component. There are no base metals used

within the equivalency calculations and this speaks to the fact that

Panuco

represents a very pure play on silver as it develops."

Exploration Activities

Zacatecas Silver has completed the first six holes at the Panuco Deposit. A total of four angled drill holes were completed at the eastern edge of Panuco Central

vein and three angled drill holes at the Panuco North vein system. Initial highlights from drilling at

Tres Cruces

in the northern part of the

Panuco

project (outside

the Mineral Resource area, and not included in the Mineral Resource Estimate announced today) include

1.85 m @ 261 g/t Ag Eq (224 g/t Ag and 0.49 g/t

Au)

from 126.05 m downhole (Hole PAN 2021-008),

2.17 m @ 823 g/t Ag Eq (798 g/t Ag and 0.34 g/t Au)

from 154.94 m downhole (Hole PAN 2021-009), and

3.00 m @ 267 g/t Ag Eq (203 g/t Ag and 0.85 g/t Au)

from 46.50 m downhole (Hole Pan 2021-010) (see Zacatecas Silver News Release dated

November 23,

2021

for details).

Zacatecas

has also commenced exploratory diamond core drilling at the San Gill Breccia located with the Zacatecas Property. The San Gill Breccia is located in

the southern part of the main

Zacatecas

concessions and is approximately 2 kilometres to the southwest of the

Veta Grande

vein. It is a zone of intense

brecciation and quartz veining with an abundant matrix of iron oxides after sulphides. Veins are multiphase — as evidenced by breccias, quartz vein stockworks,

and crustiform and colloform banding.

The San Gill Breccia is a robust exploration target that has not been effectively drill tested even though it is 800 metres long and up to 40 metres wide. Zacatecas

Silver has now completed five holes at the San Gill Breccia, with results pending.

Mineral Resource Estimate Assumptions

The Mineral Resource Estimate was generated using inverse distance cubed for gold and silver for grade interpolation within a 3-D block model, constrained by

mineralized zones defined by wireframes solid models. The bulk density values used in the Mineral Resource Estimate were derived from a regression equation

based on data measured from samples collected from re-assayed drill core completed by Zacatecas Silver.

The database for the Mineral Resource Estimate consisted of 75 drill holes totalling

23,444 m

, and 183 trenches totalling

4,540 m

, of which a total of 66 drill holes

totalling

19,826 m

and 135 trenches totalling

3,545 m

intersected the mineralization wireframes used for the Mineral Resource Estimate. The drill hole database

contained assays for silver and gold as well as other metals of no economic importance. Zacatacas Silver's seasoned exploration team carried out extensive data

verification on the historical database by re-sampling 178 historical sample intervals, being approximately 15% of sample intervals in the Mineral Resource

Estimate.

About Zacatecas Silver Corp.

The Zacatecas Silver property is located in Zacatecas State,

Mexico

, within the highly prospective Fresnillo Silver Belt, which has produced over 6.2 billion ounces

of silver. The company holds 7,826 ha (19,338 acres) of ground that is highly prospective for low and intermediate sulphidation silver-base metal mineralization

and potentially low sulphidation gold-dominant mineralization.

The property is 25 km south-east of MAG Silver Corp.'s Juanicipio Mine and Fresnillo PLC's Fresnillo Mine. The property shares common boundaries with Pan

American Silver Corp. claims and El Orito which is owned by Endeavour Silver. There are four main high-grade silver target areas within the

Zacatecas

concessions: the Panuco Deposit, Muleros, El Cristo and San Manuel-San Gill. The Property also includes

El Oro

, El Orito,

La Cantera

, Monserrat, El Peñón,

San

Judas

and

San Juan

silver-base metal vein targets. These targets are relatively unexplored and will be the focus of rapid reconnaissance
