Southern Silver Extends Oxide-Gold and Sulphide Zones at Cerro Las Minitas with 6.1 Metres Averaging 344g/t Ag, 5.7% Pb and 3.9% Zn (728g/t AgEq) and 1.0 Metre Grading 1070g/t Ag, 23.3% Pb and 3.2% Zn (1,937g/t AgEq)

Vancouver, British Columbia--(Newsfile Corp. - January 21, 2021) - Southern Silver Exploration Corp. (TSXV: SSV) (OTCQB: SSVFF) reported today further intervals of gold-enriched oxide and sulphide mineralization in step out drilling as well as a significant downhole extension of earlier reported high-grade, silver-enriched polymetallic sulphide mineralization in drill hole 20CLM-125 at the Mina La Bocona zone, Cerro Las Minitas project, Durango Mexico.

New assay results from drill hole 20CLM-125 have extended an earlier reported 19.8 metre down hole mineralized interval to a full 50.6 metres (32.2m est. TT) of semi-continuous mineralization averaging 435g/t AgEq including new higher-grade intervals of:

• a 9.3m down-hole interval (6.1m est. TT) averaging 344g/t Ag, 0.59g/t Au. 5.7% Pb and 3.9% Zn (728g/t AgEq; 18.5% ZnEq);
• a 2.2m down-hole interval (1.4m est. TT) averaging 520g/t Ag, 0.34g/t Au, 10.6% Pb and 9.8% Zn (1268g/t AgEq; 32.2% ZnEq); and
• a 7.5m down-hole interval (5.0m est. TT) averaging 364g/t Ag, 0.3g/t Au, 7.0% Pb and 1.8% Zn (678g/t AgEq; 17.2% ZnEq);

Results from drill hole 20CLM-125 have also identified:

• in the sulphide zone, a relatively narrow interval of bonanza-grade silver mineralization a further 60m down hole and adjacent to the Central Intrusion which returned a 1.4m interval (1.0m est. TT) grading 1070g/t Ag, 0.09g/t Au, 23.3% Pb and 3.2% Zn (1,937g/t AgEq; 49.1% ZnEq).
• in the upper oxide-gold zone (first reported in NR-16-20, December 16^th, 2020) an extension of the zone of mineralization to 56.8m (30.9m est. TT) averaging 0.87g/t Au and 24g/t Ag.

The mineralization identified in drill hole 20CLM-125 is the second, thick sulphide zone identified in this part of the Mina La Bocona target area. It represents a 12m to 25m lateral and down dip extension of mineralization first identified in drill hole 15CLM-078 from the 2015 drilling program and opens up the additional potential for further down-dip extensions of the sulphide mineralization which will be a continued focus of drilling in this current exploration program.

Results from drill hole 20CLM-127 which was cored up-dip from drill hole 20CLM-125, on the same azimuth, returned both gold-enriched oxide and deeper sulphide mineralization including:

• a 43.2m down-hole interval (26.5m est TT) averaging 0.37g/t Au and 26g/t Ag of shallow oxide mineralization; and
• a 10m down-hole interval (6.1m est TT) averaging 162g/t Ag, 0.57g/t Au, 3.2% Pb and 1.3% Zn (359gt/t AgEq; 9.1% Zn) that correlates with the deeper sulphide mineralization

Assay results from drill hole 20CLM-127 complement the sulphide and oxide mineralization previously identified in both drill holes 20CLM-125 and 15CLM-078 and highlight the continued exploration potential of the sulphide mineralization to depth and of the shallow oxide mineralization laterally to the southeast. Further drilling is continuing as part of the 2020-21 program to test both of these mineralized projections.

The identification of new thick zones of high-grade sulphide mineralization on the east side of the Cerro, complements the results from earlier drilling and greatly adds to the company's confidence that it can meet or exceed its exploration goals. The now expanded oxide-gold zone remains an intriguing new target for further delineation in 2021.

President Lawrence Page, Q. C. noted: "The present mineral resource estimate is based upon results derived from drill holes situate on the West side of the Cerro. Results from seventeen drill holes located on the East side of the Cerro, many containing high-grade mineralization, are not included in the 2019 Resource Estimate. Drilling currently being conducted on the east side of the Cerro is producing significant values of both oxide and sulphide mineralization, the results of which, together with results of the seventeen drill holes previously drilled, will be incorporated into an updated 43-101 Mineral Resource Estimate leading to further economic assessment studies incorporating all data later in 2021."

Table 1: Select Assay intervals from Drill Holes 20CLM-125 and 20CLM-127 in the Mina La Bocona Target

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.

Approximately 7,500 metres of drilling have now been completed of the anticipated 10,000 metres of core drilling for the 2020-21 exploration program. Drilling which was paused for the Christmas break will continue in late January with one drill focused on the Mina La Bocona target and a second drill exploring the South Skarn target.

Drilling on the east side of the Cerro will test an approximate 800 metre strike length of the South Skarn Target and Mina La Bocona Target mineralized zones to depths of up to 650 metres as well as a high-grade hanging wall zone in the Mina La Bocona Target area. These drill targets are designed to increase the current mineral resource estimate of 24 million tonnes by approximately 30%.

The CLM Project remains one of the larger undeveloped silver-lead-zinc projects in the World and is wholly owned, unburdened by royalties, fully financed and fully permitted.

1. 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 supervised directly the collection of the data from the CLM Project that is reported in this disclosure and is responsible for the presentation of the technical information in this disclosure.
