July 21, 2025

/CNW/ -

Argenta Silver Corp.

(TSXV: AGAG) (OTCQB: AGAGF)

(FSE: T1K)

("Argenta" or the "Company")

is pleased to report the first batch of assay results

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

Salta

Province

,

Argentina

. The first drill holes completed by the Company on the El Quevar Project have

delivered wide, high-grade silver intersections, and results from additional sampling of historic drill

core confirms upside for resource expansion. Surface rock sampling from underexplored areas on

the property have returned multiple high-grade silver results highlighting the growth potential of new

mineralized zones.

Highlights

QVD-410 delivers 533 g/t Ag over 20.20 meters,

including 1,320 g/t Ag over

4.00 m

(which

includes 3,549 g/t Ag over

1.00 m

), plus 484 g/t Ag over

5.00 m

, and 805 g/t Ag over

3.20 m

.

QVD-409 validates continuity with 309 g/t Ag over 26.00 meters,

including 713 g/t Ag over

8.25 m

, which also includes 1,169 g/t Ag over

2.50 m

, plus a shallow

1.00 m

with 1.22 g/t Au.

QVD-408 step-out success: 112 g/t Ag over 19.20 meters

, including 408 g/t Ag over

2.20 m

and 105 g/t Ag over

7.00 m

, extending the high-grade zone

50 m

to the southeast.

Historic core sampling:

new sampling of un-assayed historic drill core now assayed, returning

up to

602 g/t Ag over

3.00 m

including 882 g/t Ag over

1.00 m

. 35 % of historical drilling

(~ 38,000 m) has been cut and assayed, leaving some 66,000 m of core unanalyzed and

available at a low cost for potential resource expansion.

Surface sampling exceeds analytical upper detection limit of 20,000 g/t Ag

for a single

rock grab sample, with additional surface rock grab samples of 16,145 g/t and 6,004 g/t Ag

across the new Quevar South targets.

*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:

"The wait is over.

While silver spot prices are on the verge of new record highs, our first batch of results is here, a

true statement of El Quevar's potential to deliver unparalleled results. Since the company's

inception, our approach has been laser–focused on creating sustainable value for our

stakeholders. With assays returning 533 g/t Ag over 20.20 m in a drill intercept, a surface rock-chip

sample topping 20,000 g/t Ag and legacy core that has been sampled for the first time returning

positive high-grade silver results, we've only just begun to unlock the true potential of this high–

grade silver system. Expect more results from the ongoing exploration program."

2025 Winter Drilling Program Results – First Group of Results

Drilling kicked off 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 three drill

holes have been received, with results for the remaining holes expected by mid-August and mid-

September.

Of the three holes with assays in hand:

One step–out hole (QVD-408) extended the known mineralized footprint by 50 m to the

southeast

, an area previously untested by historical drilling which was recently highlighted by

Argenta's technical team to have potential. This result supports follow–up drilling in upcoming

programs and encourages the company to test the extensions of the current deposit for further

step-outs.

Two confirmation holes (QVD–409 and QVD–410) intersected multiple, broad high–grade

silver intervals within the Yaxtché Deposit

, providing fresh material to document alteration,

lithology and the consistent high–grade silver character of the mineralization.

The results from the three drill holes received to date as well as the surface rock sampling validate

the Company's existing resource model and underscore the untapped potential at El Quevar. They

confirm the high-grade, pure silver character of the mineralization and reinforce the need of

systematic exploration when less than 3% of the property has seen modern exploration.

2025 Surface Sampling Results – First 2025 Batch

Surface exploration work started on

January 3, 2025

(see news release of

January 6, 2025

),

leading Argenta to submit approximately 1,000 soil samples and over 400 rock chip samples for

laboratory analysis. Rock sampling primarily targeted the "Mani", "Andrea", "Rosa", and "Argentina"

exploration areas. Soil samples were systematically collected using a grid pattern, with 200x200-

meter and 100x100-meter spacing, and infill sampling at 50x50 meters to ensure comprehensive

coverage of the Quevar South central zone.

With numerous rock chip surface assays still pending from the laboratory, initial results already

reveal multiple high–grade silver values. More than twenty rock chip samples returned grades above

150 g/t Ag, including several exceeding 1,000 g/t Ag

. Notably:

Sample 81701

[rock grab sample]:

6,004 g/t Ag

Sample 101128

[rock grab sample]:

16,145 g/t Ag

Sample 101125

[rock grab sample]: reached the analytical upper detection limit of

20,000 g/t

Ag

20,000 g/t Ag. Visible native silver is observed on the sample (left image) and on the zoom portion of

the picture (right image), displaying native silver with pale grey metallic color and sparkly

disseminated habit. (CNW Group/Argenta Silver Corp.)

Although these high values do not reflect the deposit's average grade, they clearly demonstrate the

strong potential of the El Quevar mineral system.

Meanwhile, analytical results from the

soil sample grid

have revealed new areas with anomalous

silver values, including

soil samples reaching 147 g/t Ag and 296 g/t Ag

.

By integrating these results with historical data from previous operators, Argenta has identified

multiple new areas with highly anomalous values in silver and pathfinder elements that will guide our

technical team to define future drill targets.

The findings from the expanded surface soil geochemistry program indicate the potential of a

significantly larger mineralized system at El Quevar beyond the current resource. The well-defined

silver zone demonstrates strong continuity, while newly identified gold anomalies reveal promising

new exploration targets that were historically underexplored. Importantly, these zones have seen

minimal drilling, representing substantial untested exploration potential.

Historical Drill Core Sampling Results and Phase 1 Results

Phase 1 of the 2025 Exploration Program at El Quevar (see news release from

May 14, 2025

)

represented Argenta's first systematic evaluation of the project, targeting altered and mineralized

structures with anomalous geochemical, spectral and geophysical signatures. The principal aim in

the Quevar South area was to refine the geological model by reinterpreting and remodeling existing

historical data, and then backing it up with new, systematically collected surface samples, detailed

structural mapping and re-logging and validation of legacy core logs.

These efforts have

confirmed the strong potential for additional high–grade silver and gold mineralization in

untested targets beyond the Yaxtché deposit.

A key opportunity lies in the fact that only about 35 % of historical drilling (~ 38,000 m) has been cut

and assayed,

leaving some 66,000 m of core unanalyzed and available at a low cost for

potential resource expansion

. To kick–start this,

Argenta sampled a portion of the unanalyzed

Yaxtché drill holes (25 holes in total) and returned significant silver mineralization in five

holes

, with a standout intercept of 882 g/t Ag over

1.00 m

and an average grade of roughly

226 g/t Ag across those samples.

Particularly elevated silver grades were identified in the following drillholes:

QVD-117

[additional sampling from historical drillhole]:

148 g/t Ag over

1.00 m

, and

134 g/t Ag

over

2.00 m

, including

212 g/t Ag over

1.00 m

; both intercepts in oxide zone.

QVD-134

[additional sampling from historical drillhole]:

132 g/t Ag over

4.00 m

; in oxide zone.

QVD-211

[additional sampling from historical drillhole]:

144 g/t Ag over

6.00 m

; including

214

g/t Ag over

2.00 m

and

215 g/t Ag over

1.00 m

.

QVD-273

[additional sampling from historical drillhole]:

194 g/t Ag over

6.00 m

, including

230

g/t Ag over

2.00 m

, and

311 g/t Ag over

2.00 m

.

QVD-362

[additional sampling from historical drillhole]:

255 g/t Ag over

10.00 m

, including

175

g/t Ag over

2.00 m

, and

603 g/t Ag over

3.00 m

which includes

882 g/t Ag over

1.00 m

.

*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.

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 stage 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.
