Southern Intersects Shallow High-Grade Silver

at the South Skarn Target Including 1.4 Metres

Averaging 719g/t Ag, 14.2% Pb and 16.0g/t Zn

(1791g/t AgEq) at Cerro Las Minitas

Vancouver, British Columbia--(Newsfile Corp. - July 21, 2021) -

Southern Silver Exploration Corp.

(TSXV: SSV) ("Southern Silver")

reported today further assay results from the Cerro Las Minitas

project, Durango, Mexico, which continue to extend shallow, strongly silver-enriched sulphide

mineralization in the South Skarn target area and identify significant silver and gold assays from the

Huizache chimney at the Mina La Bocona target.

The newly released polymetallic sulphide intercepts from the South Skarn target area include:

a 2.0 metre interval (1.4 metre est. TT) averaging 719g/t Ag, 14.2% Pb and 16.0% Zn

(1791g/t AgEq)

including

a 1.5 metre interval (1.1 metre est. TT) averaging 946g/t Ag, 18.7%

Pb and 21.1% Zn (2358g/t AgEq)

from drill hole

21CLM-159;

and a deeper interval grading

a 0.5 metre interval (0.4 metre est. TT) averaging 541g/t Ag, 0.1g/t Au, 8.8% Pb and 4.0%

Zn (981g/t AgEq)

from drill hole

21CLM-159;

These highlight intercepts from drill hole 21CLM-159 which were intersected less than 200 metres below

surface, fill a significant gap between mineralization identified in this current 2020-21 drill campaign and

that identified in the earlier 2012-13 drilling and help build continuity within the known mineralized zones

identified at the South Skarn target. Current modelling has identified three panels of mineralization at the

South Skarn target, the largest of which can now be traced laterally for approximately 400 metres and up

to 580 metres down-dip.

Southern also reported additional assays from drilling at the Huizache chimney in the Mina La Bocona

target area. New Assay results include:

a 0.8 metre interval (0.5 metre est. TT) averaging 452g/t Ag, 0.5g/t Au, 2.8% Pb and 0.6%

Zn (612g/t AgEq)

from drill hole

21CLM-158;

a 0.8 metre interval (0.5 metre est. TT) averaging 27g/t Ag, 3.0g/t Au, 2.8% Pb and 0.6% Zn

(612g/t AgEq)

from drill hole

21CLM-158;

and

a 1.3 metre interval (0.9 metre est. TT) averaging 312g/t Ag, 0.12g/t Au, 2.8% Pb and 0.6%

Zn (612g/t AgEq)

from drill hole

21CLM-158;

The Huizache chimney is the third high-grade zone identified in the

Mina La Bocona target area

where

previously reported drilling identified bonanza-grade silver mineralization from the Bocona Chimney

(

8.0m of 2040g/t AgEq from drill hole 21CLM-131

; see NR-01-21) and the Muralla chimney (

6.1m of

728g/t AgEq from drill hole 21CLM-125

; see NR-02-21). Eight holes have been completed on the

Huizache chimney and assays from five of those holes remain pending.

Exploration on the property continues with one drill. Three holes remain to be tested on the east side of

the Cerro as part of the current drill program which will then transition to "greenfields" targeting on the El

Sol claim over the coming weeks. The El Sol concession, is located 2km to the northwest of the Mina La

Bocona target area and covers the northerly projection of previously identified mineralization in the Blind

Zone deposits and a second area of artisanal workings. The concession was re-acquired and

prospected by Southern in 2020 and returned anomalous values from several strongly oxidized and

silicified rocks including a dump sample

CLM-316

which assayed

0.67g/t Au, 559g/t Ag, 3.3% Pb and

4.3% Zn

.

The current drill program has now completed 54 core holes totaling 21,389 metres since drilling

recommenced in September 2020. Assay results from eight drill holes are pending and are anticipated

over the coming weeks.

Southern Silver has now tested over 750 metres of strike length along the east side of the Cerro to

depths of up to 500 metres, primarily in the South Skarn and Mina La Bocona target areas. Three

bonanza grade mineralized zones have been identified and testing of a potential fourth high-grade zone

is nearing completion, results of which will be incorporated into the upcoming mineral resource update

on the project due in August 2020.

The CLM Project remains one of the largest undeveloped silver-lead-zinc projects in the World and is

wholly owned, unburdened by royalties, fully financed and fully permitted.

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$20/oz silver, US$1650/oz gold,

US$3.25/lbs copper and US$0.9/lbs lead and US$1.15/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. 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. The Company engages in the acquisition, exploration and development either directly or through

joint-venture relationships in mineral properties in major jurisdictions.

The Company property portfolio also includes the Oro porphyry copper-gold project located in southern

New Mexico, USA, which includes patented land, State leases and BLM mineral claims totalling 22.3 sq.

km. Targeting has been finalized and bonding pending for a 5,000m drill program, designed to test

several copper-molybdenum porphyry and copper-gold skarn targets within a broad quartz-sericite-pyrite

alteration zone, interpreted to overlie an unexposed porphyry centre. Drilling is expected to commence in

Q4, 2021.

The 2019 Cerro Las Minitas Resource Estimate was prepared following CIM definitions for classification of Mineral Resources. Resources

are constrained using mainly geological constraints and approximate 10g/t AgEq grade shells. The block models are comprised of an array

of blocks measuring 10m x 2m x 10m, with grades for Au, Ag, Cu, Pb, Zn values interpolated using ID3 weighting. Silver and zinc equivalent

values were subsequently calculated from the interpolated block grades. The model is identified at a 175g/t AgEq cut-off, with an indicated

resource of 11,102,000 tonnes averaging 105g/t Ag, 0.10g/t Au, 1.2% Pb, 3.7% Zn and 0.16% Cu and an inferred resource of 12,844,000

tonnes averaging 111g/t Ag, 0.07g/t Au, 0.9% Pb, 2.8% Zn and 0.27% Cu. AgEq cut-off values were calculated using average long-term

prices of $16.6/oz. silver, $1,275/oz. gold, $2.75/lb. copper, $1.0/lb. lead and $1.25/lb. zinc. Metal recoveries for the Blind, El Sol and Las

Victorias deposits of 91% silver, 25% gold, 92% lead, 82% zinc and 80% copper and for the Skarn Front deposit of 85% silver, 18% gold,

89% lead, 92% zinc and 84% copper were used to define the cut-off grades. Base case cut-off grade assumed $75/tonne operating,

smelting and sustaining costs. All prices are stated in $USD. Silver Equivalents were calculated from the interpolated block values using

relative recoveries and prices between the component metals and silver to determine a final AgEq value. The same methodology was used

to calculate the ZnEq value. Mineral resources are not mineral reserves until they have demonstrated economic viability. Mineral resource

estimates do not account for a resource's mineability, selectivity, mining loss, or dilution. The current Resource Estimate was prepared by

Garth Kirkham, P.Geo. of Kirkham Geosciences Ltd. who is the Independent Qualified Person responsible for presentation and review of the

Mineral Resource Estimate. All figures are rounded to reflect the relative accuracy of the estimate and therefore numbers may not appear to

add precisely.

Robert Macdonald, MSc. P.Geo, is a Qualified Person as defined by National Instrument 43-101 and
