/CNW/ -

Argenta Silver Corp.

(TSXV: AGAG) (OTCQB:

AGAGF) (FSE: T1K

) ("Argenta" or the "Company")

is pleased to announce the fifth and final set

of assay results from its 2025 Winter Diamond Drilling Program (completed

mid-September 2025

) at

its 100% owned El Quevar project in

Salta Province

,

Argentina

. Drilling returned robust and

continuous, anomalous silver grades over 123.00 meters at the newly discovered

Andrea

exploration target

. The company is also pleased to announce the commencement of its summer

exploration program, highlighted by 12,000 to 15,000 meters of drilling.

Highlights:

QVD-421

intersected

123.00 meters with 5 g/t Ag

on the initial drillhole at the Andrea target,

while

QVD-422

confirmed the continuity of the target, yielding

7 g/t Ag over 100.00 metres

.

These findings confirm the presence of

a separate wide zone with anomalous silver values

located

950 m

northeast of the Yaxtché Deposit

.*

The

2025-2026 Summer Exploration Program has commenced with 2 drill rigs

at the El

Quevar Project. It is expected that 12,000 to 15,000 meters will be drilled between

November

2025

and

June 2026

.

A recap of the 2025 Winter Drilling Program has been included in this announcement.

*Intervals 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:

"The final assay

results from our 2025 Winter Program have just been received, coinciding with the launch of our

2025–2026 Summer Drilling Campaign. The winter program, which totaled 4,244 meters, delivered

strong results for what we consider to be the foundational campaign of Argenta Silver Corp. These

results, together with extensive surface and desktop work, have guided the design of an ambitious

exploration plan for the Argentine summer season spanning from

November 2025

through

June

2026

. During this period, we plan to complete 12,000 to 15,000 meters of drilling, supported by

geophysics, surface sampling, geological mapping, and advanced alteration and metallurgical

studies. Capital allocation has been designed strategically, with approximately 40% directed

toward resource expansion and 60% toward exploration and new discoveries. At present, two rigs

are already turning, and we expect to begin receiving results in the coming weeks."

2025 Winter Drilling Program Results – Fifth and Final Group of Results

The 2025 Winter Drilling Program commenced in late May and concluded in the second week of

September. The program achieved 4,244 meters of drilling and was designed to confirm known

high

grade zones, step out along strike, and test new targets. As part of the continuous disclosure

culture of the company, assays from the first group of results were announced on

July 21, 2025

(see

news release from

July 21, 2025

), from the second group of results on

August 13, 2025

(see news

release from

August 13, 2025

), third group of results on

September 23, 2025

(see news release

from

September 23, 2025

), and the fourth group of results on

October 27, 2025

(see news release

from

October 27, 2025

).

Exploration drillholes

QVD-421 and QVD-422

(Table 1) have successfully identified silver

mineralization within the

new exploration target, Andrea

, located approximately

950 meters

northeast of the

Yaxtché

Deposit.

Both exploration holes returned multiple intercepts with anomalous silver values,

in cases

surpassing intervals of 100 meters.

* These initial exploration holes suggest

a new high-

sulphidation zone

that remains preserved beneath the surface cover. In consideration of this, the

Andrea target has become one of the priorities to follow up during the 2025-2026 Summer Program

that has recently commenced.

"Anomalous silver values" refers to geochemical assay results that indicate silver concentrations

exceeding the natural background levels typically found in unmineralized country rock. In the case of

these targets, average background silver values are generally below 0.5 g/t Ag; therefore, any

assay returning values above this 0.5 g/t Ag threshold is considered anomalous and serves as a

geochemical indicator of potential mineralization.

2025–2026 Summer Drill Program Commencement

Argenta Silver Corp. is also pleased to announce the commencement of its

2025–2026 Summer

Drilling Program, which encompasses 12,000 to 15,000 meters of planned diamond drilling

.

The program officially commenced on

November 1, 2025

, and is expected to continue through

June

2026

. At present,

two drill rigs are fully operational, working simultaneously

across different

sectors of the El Quevar Project.

Management has strategically structured the campaign with approximately

40% of capital allocated

to the Resource Expansion Program and 60% to the New Discoveries Program

. By advancing

both initiatives concurrently, Argenta continues to implement an aggressive, results-driven exploration

strategy aimed at expanding the known mineral resource while identifying new zones of

mineralization within a property that remains largely underexplored.

In addition to drilling, the Summer Program includes a comprehensive suite of surface exploration

and technical studies, comprising geological mapping, soil and rock sampling, geophysical surveys,

and detailed alteration, metallurgical, paragenetic, petrographic, mineralogical, and structural

analyses.

The principal focus of the current campaign will be

Quevar South

, where extensive drilling and

surface work are underway, while Quevar North remains open for evaluation in future seasons.

Despite the scale of planned activity, the breadth of the Quevar South area ensures that significant

portions of the property will remain open for continued exploration beyond this campaign.

2025

Winter Drilling Program Recap

Argenta Silver Corp. started a fully funded winter program that commenced in late

May 2025

and

was completed in

mid-September 2025

. The program was designed to confirm known high-grade

zones, step out along strike, and test new exploration targets.

A total of

16 drill holes were successfully completed, totalling 4,244 metres

(Figure 01). The

results were disclosed in 5 batches, being this current news release the fifth and final batch of the

2025 Winter Program.

Highlights of the 2025 Winter Program Drill Results:

Confirmation drilling:

QVD-409:

Delivered a result of 309 g/t Ag over 26.00 metres, including high-grade of 713 g/t

Ag over

8.25 m

, which in turn contained a high-grade interval of 1,169 g/t Ag over

2.50 m

. The

hole also included a separate, shallow intercept of 1.22 g/t Au over

1.00 m

(Figure 03).

QVD-410:

Returned an intersection of 533 g/t Ag over 20.20 metres. This zone contained

multiple high-grade intervals, including 1,320 g/t Ag over

4.00 m

(which includes 3,549 g/t Ag

over

1.00 m

), 484 g/t Ag over

5.00 m

, and 805 g/t Ag over

3.20 m

(Figure 03).

QVD-411 & QVD-411B:

Hole QVD-411 was halted at 92 metres due to operational challenges

before reaching the proposed target depth. It was re-drilled as QVD-411B, delivering a high-

grade intersection of 263 g/t Ag over 35.00 metres. This included multiple high-grade intervals

such as 425 g/t Ag over

6.00 m

and 342 g/t Ag over

9.00 m

(which includes 694 g/t Ag over

2.1

m

). The hole also intercepted associated gold values of up to 0.84 g/t Au over

1.00 m

.

Step-out drilling:

Results confirmed

the deposit remains open at depth and along strike

to the northwest and

east.

QVD-408:

This hole extended the resource 50 metres to the southeast by intersecting 112 g/t

Ag over 19.20 metres. This intercept included higher-grade sections of 408 g/t Ag over

2.20 m

and 105 g/t Ag over

7.00 m

(Figure 03).

QVD-414:

High-grade intersection of 545 g/t Ag over 43.20 metres. This included significant

intercepts of 1,302 g/t Ag over

8.00 m

and 905 g/t Ag over

7.70 m

, effectively extending the

resource zone to the northwest for

+70 m

(Figure 03).

Gap infill drilling:

QVD-412:

This hole delivered a wide intercept of 1,026 g/t Ag over 40.00 metres (Figure 03).

This zone contained high grades, including 2,246 g/t Ag over

15.00 m

, which itself included

4,423 g/t Ag over

6.00 m

. This hole featured the project-record grade intersection of

18,467 g/t

Ag over

1.05 m

(Figure 04).

Up-dip drilling:

QVD-413:

Intersected 414 g/t Ag over 14.35 metres, including high-grade intervals of 795 g/t

Ag over

3.00 m

and 466 g/t Ag over

4.00 m

. This hole expanded the up-dip potential for the

existing resource (Figure 03).

QVD-415:

This hole was strategically placed to test for the upper edge of the mineralised zone.

The drilling successfully validated the Company's geological model.

Exploration drilling:

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.

QVD-417 & QVD-418

(Atenea exploration target): These follow-up holes returned anomalous

silver results and pathfinder elements that are in coherent coincidence with the other holes in the

area. This outcome reinforces the presence of mineralisation within the new exploration target

Atenea.

QVD-419

(Mani exploration target): This hole returned broad anomalous silver values of 30 g/t

Ag over 23.00 metres. This finding suggests the potential for significant additional mineralisation

near the surface.

QVD-420

(Mani exploration target): the hole intersected 204 g/t Ag over 2.00 metres. This

result definitively confirms the presence of a distinct mineralised trend south of the main deposit.

QVD-421

(Andrea exploration target): Returned continuous intercept of 5 g/t Ag over 123.00

metres. This zone included higher-grade intervals of 57 g/t Ag over

1.00 m

and 65 g/t Ag over

1.00 m

, plus an associated gold intercept of 0.42 g/t Au over

1.00 m

.

QVD-422

(Andrea exploration target): Confirmed the size potential of the target, yielding 7 g/t

Ag over 100.00 metres, including 23 g/t Ag over

8.00 m

.

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.

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.
