Southern Intersects High-grade Copper-Silver-

Gold at the Bocona Target with 6.3 Metres

Averaging 134g/t Ag, 0.5g/t Au, 2.3% Cu (461g/t

AgEq) including 1.1 Metres Averaging 567g/t

Ag, 2.3g/t Au 11.2% Cu (2,106g/t AgEq)

Vancouver, British Columbia--(Newsfile Corp. - March 29, 2021) -

Southern Silver Exploration Corp.

(TSXV: SSV) (OTCQB: SSVFF) (Santiago: SSVCL) reported today that it has identified high-grade

copper-gold-silver mineralization in a down-dip step-out from previously reported bonanza grade silver

mineralization in the Mina La Bocona target area at the Cerro Las Minitas project, Durango Mexico.

Polymetallic sulphide intercepts from the Mina La Bocona target area include:

a 12.1 metre down hole interval (6.3 metre est. TT) averaging 134g/t Ag, 0.5g/t Au 2.3% Cu

(461g/t AgEq) including a 2.1 metre down hole interval (1.1 metre est. TT) averaging 567g/t

Ag, 2.3g/t Au, 11.2% Cu (2,106g/t AgEq) from drill hole 21CLM-135 in the Bocona

Chimney; and

a 5.4 metre down hole interval (3.8 metre est. TT) averaging 217g/t Ag, 0.3g/t Au, 3.3% Pb

and 0.7% Zn (377g/t AgEq) from drill hole 21CLM-136 in the Muralla Chimney.

The mineralization identified in drill hole 21CLM-135 is an extension of the second, thick polymetallic

sulphide lens identified in the Mina La Bocona target area on the eastern side of the Cerro and is an

approximate 50 metre down-dip step-out from previously reported bonanza-grade silver in drill hole

20CLM-131

(8.0m est. TT averaging 1,072g/t Ag, 18.8% Pb and 7.5% Zn or 2040g/t AgEq; see

NR-02-21).

The mineralization is relatively shallow (<350 metres below surface) and

remains open to

depth for further testing in the remaining drill program.

Bocona Oxide-Gold Target

The Company also reports that it has identified additional gold-enriched intercepts within the near-

surface oxide-gold zone, identified earlier in the 2020-21 drill program, which sits above and out-board

of the main sulphide targets at Mina La Bocona. Drilling returned:

a 6.0 metre down hole interval (4.2 metres est. TT) averaging 241g/t Ag, 1.4g/t Au, 7.3% Pb

and 2.5% Zn (686g/t AgEq) including a 1.8 metre down hole interval (1.3 metres est. TT)

averaging 525g/t Ag, 3.5g/t Au 15.1% Pb and 2.4% Zn (1370g/t AgEq) from drill hole

21CLM-136 starting at 170.3 metres down hole;

and several narrower, higher grade intervals including:

a 0.8 metre interval (0.4 metre est. TT) averaging 153g/t Ag, 5.7g/t Au (658g/t AgEq) from

drill hole 21CLM-135 starting at 166.2 metres down hole; and

a 0.5 metre interval (0.4 metre est. TT) averaging 44g/t Ag, 7.8g/t Au (808g/t AgEq) from drill

hole 21CLM-136 starting at 104.8 metres down hole.

Drilling on the oxide-gold target continues to extend the lateral projection of this shallow mineralized zone

which remains a compelling target for further drill testing. Additional drill step-outs have been completed,

with assay results pending, which will provide better resolution of both the target type and resource

potential.

Rob Macdonald, Vice President Exploration, stated:

"Drilling in the Mina La Bocona target area

continues to extend the two polymetallic sulphide zones and the near surface gold mineralization

identified earlier in the 2020-21 drilling. The drill program, which was recently expanded from an initial

10,000 metre program to a 20,000 metre program, will continue to focus on the development of these

targets and the systematic investigation of further mineralization located to the northwest along the

east side of the Cerro."

Exploration on the property continues with two drills targeting the east side of the Cerro and has now

completed 33 core holes totaling 13,745 metres since restarting drilling in September 2020. Assay

results from 11 drill holes are pending and are anticipated over the coming weeks.

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.

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
