Southern Silver Returns 8.9 metres of 222g/t

AgEq in South Skarn Drilling, Cerro Las

Minitas Project Mexico

Vancouver, British Columbia--(Newsfile Corp. - February 26, 2025) -

Southern Silver Exploration

Corp.

(TSXV: SSV) (OTCQX: SSVFF) (the "Company" or "Southern Silver") reports today that results

from its Q4 '24 "proof of concept" drilling has extended silver-polymetallic mineralization both laterally

and down dip of the South Skarn deposit on the Cerro Las Minitas project, Durango, Mexico.

Six core holes totalling 2395 metres were completed as part of the drill program.

Drilling tested gaps

within the current block model, lateral extensions of the mineralization and successfully intersected thick

intervals of mineralized skarn in a hole which tested the depth projection of the main mineralized shoot of

the South Skarn deposit.

Drilling highlights from hole 24CLM-198 include:

a

0.5 metre interval (est. TT.)

averaging

154g/t Ag

, 0.2g/t Au,

5.6% Cu

and 0.1% Zn (

834g/t

AgEq

) within a

8.9 metre interval (est. TT.)

averaging

97g/t Ag

, 0.1g/t Au,

0.7% Cu

, 0.1% Pb

and 0.7% Zn

(222g/t AgEq)

; and

a

4.0 metre interval (est. TT)

averaging

81g/t Ag

, 0.2g/t Au, 0.1g/t Cu, 0.4% Pb and

3.9% Zn

(

267g/t AgEq

);

Strong gold-enrichment is also identified in several hangingwall intercepts in 24CLM-198 correlating to

zones of mineralization outboard of the more typical, silver-enriched polymetallic mineralization of the

main skarn horizon located adjacent to the central monzonite intrusion. Highlights include:

a

0.9 metre interval (down hole)

averaging

124g/t Ag, 5.2g/t Au

and

4.0% Pb (682g/t AgEq);

and

a

5.1 metre interval (down hole)

averaging

7g/t Ag, 1.8g/t Au (167g/t AgEq)

Drilling also returned a 3.5 metre (est. TT) sulphide skarn interval in drill hole 24CLM-199 representing

an approximate 175 metre lateral step out from the skarn intercepts in drill hole CLM-198 and returned

shallow gold-enriched oxidized intercepts in several other drill holes.

Vice President of Exploration, Rob Macdonald stated "

This recent drilling successfully demonstrates

both the lateral and down dip extensions of relatively shallow mineralization around the South Skarn

deposit. Similar shallow targets are identified around both the Bocona and North Felsite deposits.

Mineralization also remains open at depth, particularly on the eastern side of the Cerro which with

further exploration, can continue to add high margin mineralization early in the modelled production

scenario."

The Company also 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, 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 average metal prices of: US$23.00/oz silver, US$1850/oz gold,

US$4.00/lbs copper and US$1.00/lbs lead and US$1.25/lbs zinc. AgEq and ZnEq calculations did not account for relative metallurgical recoveries of

the metals. Ore-grade 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-
