Southern Silver Exploration Corp.: Hits High-Grade Extension at Cerro Las Minitas

• a 17.6m down hole interval (12.5m est. True Thickness) averaging 154g/t Ag, 2.0g/t Au, 3.2% Pb and 3.9% Zn (558g/t AgEq; 15.7% ZnEq) starting at 229.9m downhole, including a higher grade 4.2m interval (3.0m est. TT) averaging 329g/t Ag, 4.6g/t Au, 7.4% Pb and 7.3% Zn (1175g/t AgEq; 33.2% ZnEq); and
• a 10.1m down hole interval (9.2m est. TT) averaging 220g/t Ag, 0.3% Cu, 3.6% Pb and 5.4% Zn (574g/t AgEq; 16.2% ZnEq) starting at 462.5m down hole, including a higher grade 2.3m interval (2.1m est. TT) averaging 373g/t Ag, 0.9% Cu, 7.4% Pb and 10.3% Zn (1089g/t AgEq; 30.7% ZnEq).

The upper mineralized intercept in hole 17CLM-101 is spatially related to thick intervals of monzonite/felsite and appears to be the southeast extension of the Blind Zone deposit. The deeper intercept is an approximate 125 metre lateral offset from mineralization in 11CLM-025 (10.8m down hole of 182g/t Ag, 0.5% Cu, 1.6% Pb and 6.4% Zn) and is localized along the leading edge of the skarn surrounding the Central Intrusion (Skarn Front zone). Neither hole 11CLM-025 nor the hole located immediately to the southeast of 17CLM-101 (12CLM-040) tested the Blind Zone target.

Results from hole 17CLM-101 are significant in:

• the identification of relatively shallow, precious-metal-enriched mineralized intervals in two separate zones which remain open and largely untested for over 500 metres laterally to the southeast and for up to 500m down dip from hole 17CLM-101; and

• the identification of gold values (up to 4.6g/t Au over 3.0m est. TT) in the upper interval which is of particular geological interest in further enhancing the value of the newly discovered intercept.

Approximately 10,650 metres in 14 drill holes has now been completed in the planned US$2 million 2017 exploration program. Drilling will continue through July on both the North Skarn target and extensions of the Blind and Skarn Front zones to the southeast.

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$18.2/oz silver, US$1240/oz gold, US$2.8/lbs copper and US$0.91/lbs lead and US$0.94/lbs zinc. AgEq and ZnEq calculations did not account for relative metallurgical recoveries of the metals. Ore-grade composites calculated using a 80g/t AgEq cut-off and <20% internal dilution, except where noted; anomalous intercepts calculated using a 10g/t AgEq cut-off.

Cerro Las Minitas Project

Exploration on the company's flagship Cerro Las Minitas property, Durango Mexico is funded by Electrum Global Holdings L.P. ("Electrum"), which has financed a broad range of exploration activities and has earned a 60% interest in the project through a US$5.0M earn-in on the property, with Southern Silver acting as operator.

The Cerro Las Minitas project as of March 21^st, 2016 contains an estimated Inferred Resource of 17.5Mozs silver and 237Mlbs of lead and 626Mlbs zinc (77.3Mozs AgEq) and an estimated Indicated Resource of 10.8Mozs silver, 189Mlbs lead and 207Mlbs zinc (36.5Mozs AgEq).⁽¹⁾

A total of 104 drill holes for 46,351 metres have now been completed on the Cerro Las Minitas project with exploration expenditures of approximately US$10.8 million.

About Southern Silver Exploration Corp.

Southern Silver Exploration Corp. is a precious metal exploration and development company with a focus on the discovery of world-class mineral deposits in north-central Mexico and the southern USA. Our specific emphasis is the 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, 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, along with our partner, Electrum Global Holdings LP, 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. Our property portfolio also includes the Oro porphyry copper-gold project located in southern New Mexico, USA.

1. The 2016 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 and AgEq values interpolated using ID² weighting. The models identified at a 150g/t AgEq cut-off, an indicated resource of 3,724,000 tonnes averaging 90g/t Ag, 0.05g/t Au, 2.3% Pb, 2.5% Zn and 0.09% Cu and a cumulative inferred resource of 6,611,000 tonnes averaging 82g/t Ag, 0.17g/t Au, 1.6% Pb, 4.3% Zn and 0.2% Cu. Mineral Resource cut-offs are estimated using an average long-term price of $15/oz silver, $1,100/oz gold, $2.75/lb Cu, $0.90/lb lead and $0.90/lb zinc and metal recoveries of 82% silver, 86% lead and 80% zinc. AgEq calculations did not account for relative metallurgical recoveries of the metals. All prices are stated in $USD. Mineral Resources are conceptual in nature and as such do not have demonstrated economic viability.
