VANCOUVER, BC

,

Sept. 23, 2025

/CNW/ -

Argenta Silver Corp.

(TSXV: AGAG) (OTCQB:

AGAGF) (FSE: T1K)

("Argenta" or the "Company")

is pleased to report the third batch of assay

results from its 2025 winter diamond drilling program at the 100% owned El Quevar Project in

Salta

Province

,

Argentina

. These results indicate ongoing continuity of the Yaxtché Deposit for 70 meters

to the northwest (step-out hole

QVD-414

) extending the known mineralized footprint, while additional

drill results highlight a promising new exploration target named Atenea. The 2025 Winter Drill

Program has been completed, and the company is already working on plans for the upcoming

summer drill season. Remaining results from the 2025 Winter Program are still pending.

Highlights

QVD-414 - step-out success: 545 g/t Ag over 43.20 meters,

including

1,302 g/t Ag

over

8.00 m

and including

905 g/t Ag

over

7.70 m

,

extending the resource zone to the

northwest.

*

QVD-416 – initial test of the new Atenea target: 314 g/t Ag over 2.00 meters.

This result

indicates the

potential for discovery of new mineralization zones

and the expansion of the

overall scope of the project. *

*Intervals shown are core length. Estimated true widths vary between 60 to 85% of core reported length. Insufficient re-modelling and drill density on new data has been completed

to calculate true width at this time.

Joaquin Marias, CEO, President and Director of Argenta Silver Corp. commented:

"With silver

prices at record highs, our team continues to deliver strong results at El Quevar. A successful 70-

meter step-out drillhole down-plunge of the existing resource returned 43.20 meters averaging 545

g/t silver, providing clear motivation to continue drilling along this trend. In parallel, a newly

defined target named Atenea—in honor of the goddess of knowledge and strategy—has yielded

encouraging intercepts, including 2.00 meters at 314 g/t silver and multiple additional silver values,

positioning it as a compelling new target within the project. We are also awaiting assay results

from six drillholes, including the exploration targets Andrea and Mani. With the 2025 Winter

Program now complete, our team is actively preparing for the upcoming program, which is

expected to commence in

October 2025

."

2025 Winter Drilling Program Results – Third Group of Results

Drilling commenced in late May as part of a fully funded 4,000 m winter campaign designed to

confirm known high–grade zones, step out along strike, and test new targets. Assays from the first

group of results were announced on

July 21, 2025

(see news release from

July 21, 2025

) and from

the second group of results on

August 13, 2025

(see news release from

August 13, 2025

). The

2025 Winter Drilling Program concluded in the second week of September. Pending results from the

remaining drillholes are expected by early and late October. The company is currently working on a

drill plan for the next program.

Of the four drill holes from the third batch of results with assays in hand (see Figure 01):

One step–out hole (QVD-414) successfully extended the known mineralized footprint by

70.50 meters

to the northwest (see Figure 02). This area was previously untested by historical

drilling and was recently identified by Argenta's technical team as having strong potential. The

positive result encourages the company to further test the down plunge extension of the current

deposit with additional step-out drill holes and supports infill drilling in upcoming campaigns.

Up-dip expansion drillhole (QVD-415)

was strategically placed to test for the upper edge of

the mineralized zone. This drilling successfully validated the company's geological model,

providing crucial information about the deposit's boundary.

Exploration drillholes

(QVD-416

and

QVD-417)

have successfully identified a new exploration

target, named

Atenea

. Located approximately

400- and 700-meters north

of the Yaxtché

Deposit, with one hole returning significant silver values and the other returning anomalous silver

values. These results indicate the potential for new mineralization zones, which may expand the

overall scope and upside of the project.

Completion of 2025 Winter Drill Program

Argenta Silver Corp. is also pleased to report the successful completion of its

2025 Winter Drill

Program

, which commenced in late May and concluded on

September 11, 2025

. The program,

designed for 4,000 meters, was completed with a total of

16 drillholes for 4,244 meters

.

To date, results from

10 drillholes (2,409 meters)

have been released, including those disclosed in

this announcement. Assays for the remaining six drillholes are pending and are expected to be

received in

October 2025

.

With the winter program complete, Argenta is advancing preparations for the

2025–2026 Summer

Drill Program

, which reflects the interannual summer season in the Southern Hemisphere. The

Company is

fully funded

for this next campaign, targeting between

12,000 and 15,000 meters of

drilling

.

Capital allocation will be directed as follows:

40%

to the

Resource Expansion Program

; and

60%

to the

New Discoveries Program

.

Both programs will run

in parallel and simultaneously

, underscoring Argenta's aggressive

approach to exploration. This strategy is designed to advance the potential expansion of the existing

resource while unlocking new discoveries across a property that has historically seen exploration

over only 3% of its surface area.

Management believes this dual focus positions the Company to maximize the upside exploration

potential of the El Quevar Project while continuing to strengthen the resource base.

About El Quevar Project

The El Quevar Project is located in Salta,

Argentina

and spans an area of 57,000 hectares. The

property remains underexplored with less than 3 % of the area covered with comprehensive

exploration work. The property boasts exceptional infrastructure with over 60 km of internal roads, a

fully owned, fully operational camp for 100 workers with multiple support buildings, and a railroad,

gas pipeline and service road just 3 km from camp, while a high–voltage transmission line lies

approximately 20 km from the exploration area. The robust infrastructure associated with the project

provides a cost-effective platform to de–risk and accelerate future drilling and development.

The foundational Mineral Resource Estimate of the Yaxtché deposit boasts an indicated mineral

resource of

45.3 million ounces of silver from 2.93 million tonnes grading 482 g/t Ag

, and an

inferred resource of

4.1 million ounces from 0.31 million tonnes grading 417 g/t Ag

(1). The

mineral resource area remains open at depth and in multiple directions, particularly to the southeast

and northwest. One of the objectives of the 2025 Winter Drilling Program is to specifically target and

expand these high-grade Yaxtché zones.

The mineralization at the Yaxtché deposit is defined as a silver rich, high to intermediate-sulphidation

epithermal system with associated gold. Mineralization is controlled by NW-SE and NE-SW fault

structures and is mainly hosted in brecciated zones and dacite domes. Silver minerals at Yaxtché

consist of complex silver sulphides, sulphosalts and native silver. These minerals are found within

silicified breccias, commonly appearing as veinlets, stockworks, disseminations, and breccia fillings.

QAQC Statement

The Company adheres to CIM Best Practices Guidelines for exploration-related activities conducted

on its property. Quality Assurance and Quality Control (QA/QC) procedures are overseen by a

Qualified Person.

All geochemical sample assay results from

Argenta Silver

have been independently monitored

through a rigorous QA/QC protocol. This protocol includes the regular insertion of blind standard

reference materials, blanks, and duplicates.

The logging and sampling of the El Quevar drill core were completed at Argenta's core handling

facilities in Salta,

Argentina

. Drill core was diamond-sawn on-site, and half drill-core samples were

securely transported to Alex Stewart Laboratories' (ASI) sample preparation facilities in Jujuy, and

forwarded to their facility in Mendoza,

Argentina

for analysis. The other half-core is retained on site

for reference.

Soil samples were prepared by drying and sieving to minus 80 mesh. Rock chip and diamond drill

core samples were dried and then underwent 2 stages crushing to 80% passing minus 10 mesh

before collecting a 600-gram split that was pulverized to 90% passing -140 mesh. A 200-gram split

is sent for analysis and the remaining 400g is archived. All samples were analyzed for gold using a

fire assay on a 50-gram sample with an AAS finish, and for 39 elements by 4 acid, ICP-OES on a

0.2-gram sample. Soils were also analyzed for mercury using cold vapor AA on a 0.2-gram.

Overlimit silver was determined by a 50-gram fire assay with a gravimetric finish and over limit lead,

zinc and copper were determined by ICP_OES using a mixture of highly oxidizing acids on a 0.2-

gram sample.
