Southern Silver Intersects 4.6 metres

Averaging 201g/t Ag, 4.5% Pb and 9.8% Zn

(557g/t AgEq) at Cerro Las Minitas Project in

Durango, México

Vancouver, British Columbia--(Newsfile Corp. - April 1, 2026) -

Southern Silver Exploration Corp.

(TSXV: SSV) (OTCQX: SSVFF) (the "Company" or "Southern Silver") reports the final assays from

drilling on the Puro Corazon claim which continues to extend mineralization to depth and identify

additional thick intervals of high-grade and strongly silver-enriched polymetallic mineralization.

Highlight assays include:

a

4.6 metre interval

averaging

201g/t Ag

, 0.1%g/t Cu,

4.5% Pb

and

9.8% Zn

(557g/t AgEq),

including a

1.5 metre interval

averaging

401g/t Ag

, 0.2% Cu,

8.9% Pb

and

22.3% Zn

(

1181g/t

AgEq

)

(1)

from drillhole

26CLM-221; and

a

9.3 metre interval

averaging

62g/t Ag

, 0.1% Cu, 0.2% Pb and

6.0% Zn

(234g/t AgEq),

including a

2.2 metre interval

averaging

135g/t Ag

, 0.2% Cu, 0.4% Pb and

13.5% Zn

(

522g/t

AgEq

)

(1)

from drillhole

26CLM-223.

(1) see AgEq calculation criteria in notes to Table 1. Intervals are reported as estimated true thickness unless otherwise indicated

Both skarn and replacement styles of mineralization are identified in these holes with several intercepts,

located well outboard of the Skarn zone, correlating with previous identified mineralization in the El Sol

structural zone.

All twenty-three of the planned holes in the current drill program are now complete and drill crews have

been demobilized from the property. Analyses from all drill holes have been reported. Sampling and

mapping within the 13 levels of the historic Puro Corazon mine workings continues with up to 212

channel samples totaling over 1300 individual samples having been collected to date. Assay results from

this sampling are being compiled and will be reported in the coming weeks.

Vice President of Exploration, Rob Macdonald stated "

The 2025-26 drill program successfully outlined

and upgraded mineralization on the Puro Corazon claim; extending mineralization within the skarn-

altered halo around the main intrusion for upwards of 400 metres laterally and to depths of up to 500

metres below surface, where it transitions into previously identified mineralization in the larger CLM

claim block. More significantly, drilling also intersected multiple bonanza-grade, replacement-styled

intercepts on the outer edge of the skarn-altered halo, potentially forming a shallow high-grade lens

outboard of the main skarn zone and starting within 200 metres of surface. This mineralization is

adjacent to existing historical mine workings and could be accessed early in a mine plan scenario."

Next Steps

The Company is planning to incorporate the results of the Puro Corazon drilling program into the much

larger Cerro Las Minitas project which is expected to significantly enhance the project economics and

the scalability of the mine plan. Final assay results have been received and the next steps for the

Company include:

update the Mineral Resource Estimate of the Cerro Las Minitas project; followed by

an update of the Preliminary economic Assessment ("PEA") of the project in accordance with the

provisions of National Instrument 43-101 and

continue to advance baseline data collection and permit readiness review

The Company reports that work on the Cerro Las Minitas project continues advancing numerous upside

opportunities identified subsequent to the July 2024 PEA, while also derisking and advancing the project

with the commencement of baseline data collection, hydrology, geotechnical, archaeological and land

surveys and studies.

As currently modelled, the Cerro Las Minitas project features a large-scale underground mining

operation with robust project economics and high gross revenues in a well located and mining friendly

jurisdiction in southeast Durango, Mexico. For more information on the details of the current economic

assessment of the Cerro Las Minitas project please refer to Southern Silver's news release dated June

10, 2024.

Analyzed by FA/AA for gold and ICP-AES by ALS Laboratories, North Vancouver, BC. Silver (>100ppm), copper, lead and zinc (>1%) overlimits

assayed by ore grade ICP analysis,

2)

High silver overlimits (>1500g/t Ag) and gold overlimits (>10g/t Au) re-assayed with FA-Grav. High Pb (>20%) and Zn (>30%) overlimits assayed

by titration. AgEq and ZnEq were calculated using prices of $2,800/oz Au, $32/oz Ag, $4.50/lb Cu, $0.95/lb Pb and $1.25/lb Zn.

3)

AgEq and ZnEq calculations utilized relative metallurgical recoveries of Au 48.6%, Ag 93%, Cu 70%, Pb 87% and Zn 93%.

4)

Composites are calculated using a 80g/t AgEq cut-off in sulphide and 0.5g/t AuEq in the oxide gold zone. Composites have <20% internal dilution,

except where noted; anomalous intercepts are calculated using a 10g/t AgEq cut-off.

About Southern Silver Exploration Corp.

Southern Silver Exploration Corp. is an exploration and development company with a focus on the

discovery of world-class mineral deposits either directly or through joint-venture relationships in mineral

properties in major jurisdictions. Our specific emphasis is the 100% owned Cerro Las Minitas silver-

lead-zinc project located in the heart of Mexico's Faja de Plata, which hosts multiple world-class mineral

deposits such as Penasquito, Los Gatos, San Martin, Naica and Pitarrilla. We have assembled a team

of highly experienced technical, operational and transactional professionals to support our exploration

efforts in developing the Cerro Las Minitas project into a premier, high-grade, silver-lead-zinc mine.

Located in the same State as the Cerro Las Minitas property is the newly acquired Nazas, gold-silver

property. Our property portfolio also includes the Oro porphyry copper-gold project and the Hermanas

gold-silver vein project where permitting applications for the conduct of a drill program is underway, both

located in southern New Mexico, USA.
