Southern Silver Identifies New Drill Targets at CLM West

Claims

Vancouver, British Columbia--(Newsfile Corp. - February 21, 2018) -

Southern Silver Exploration Corp. (TSXV: SSV)

(OTCQB: SSVFF) (FSE: SEG1) ("Southern Silver")

reported today that recent surface sampling targeting precious-metal

enriched epithermal vein systems on its newly staked CLM West claim group (Creston del Oro, Biznagas and Los Lenchos

claims) has identified several new drill targets for RC drill testing in Q2 2018.

Recent sampling on the four square kilometre

T3

Target

area returned elevated precious metal and pathfinder values in multiple

float samples including two distinct clusters of strongly anomalous silver values (up to 317g/t Ag), gold values (up to 0.64g/t Au),

antimony values (up to 9920ppm Sb) and a +1000 metre trend of strongly elevated mercury (up to 37.3ppm Hg). Further

sampling to the northwest and southeast of the T3 area currently is underway to determine the lateral extent of the anomalies.

The T3 area represents a previously unrecognized target

area

that sits several kilometres to the northeast of

,

and

parallel to,

the already established mineralized trend transecting the CLM West claim group

(see Figure 2).

Surface exploration in the CLM West claim package is targeting high-grade epithermal silver-gold quartz vein systems within

Tertiary volcanic stratigraphy which are found in a geologically similar environment to the vein system at the Avino Mine located

approximately 10 km to the NW of the northern claim boundary of the CLM West claim group and at Hecla's San Sebastian mine

located approximately 40km to the east of the target area.

Southern Silver also reported that community consultations and agreements are completed and Environmental

permitting/reporting is in progress and nearing completion.

CLM West Sampling Program

Summary

Sampling has been conducted throughout the three claim groups over the last several months with collected samples consisting

of mostly quartz and rhyolite float. Mapping in areas of exposure in the northern areas of the claims has identified multiple quartz

veins and silicified zones up to 15 metres thick.

Over 2400 rock chip and float samples have been collected in the CLM West claims to date and identify a +12 kilometre long

northwest-southeast-trending corridor of anomalous precious-metal and pathfinder values that display a distinct zoning pattern

consistent with modelled vertical and lateral zonation within a large epithermal vein system. Multiple distinct clusters and trends

are seen in the metal distribution which will form the basis for drill targeting in the gravel covered areas.

Cerro Las Minitas Project

Recent exploration on the company's flagship Cerro Las Minitas property, Durango Mexico has been funded by Electrum Global

Holdings L.P. ("Electrum"), which has now earned a 60% indirect interest in the property through a US$5.0M earn-in on the

property, with Southern Silver acting as operator of on-going joint venture operations.

The Cerro Las Minitas project as of January 8

th

, 2018 contains an estimated Inferred Resource, at a 175g/t AgEq cut-off, of

33.6

Mozs silver and

319

Mlbs of lead and

813

Mlbs zinc

(

116.1

Mozs AgEq)

and an estimated Indicated Resource of

20.7

Mozs silver,

131

Mlbs lead and

870

Mlbs zinc (

92.7

Mozs AgEq)

.

A total of 108 drill holes for 49,600 metres have now been completed on the Cerro Las Minitas project with exploration

expenditures of approximately US$15.1 million with an exploration cost of $0.07 per AgEq ounce.

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, Los Gatos 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. The Oro property consists of patented land, State leases and BLM located mineral claims which

cover a highly prospective quartz-sericite-pyrite alteration zone, interpreted to overlie an unexposed porphyry centre and distal

sediment-hosted, oxide-gold target.

The 2018 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 ID

2

weighting. The models identified at a 175g/t AgEq cut-off, an indicated resource of

10,135,000 tonnes averaging 102g/t Ag, 0.1g/t Au, 1.4% Pb, 3.6% Zn and 0.15% Cu and a cumulative inferred resource of

8,685,000 tonnes averaging 74g/t Ag, 0.04g/t Au, 0.7% Pb, 4.5% Zn and 0.15% Cu. Mineral Resource cut-offs are

estimated using an average long-term price of $16/oz silver, $1,200/oz gold, $2.75/lb Cu, $1.00/lb lead and $1.10/lb zinc

and metal recoveries of 82% silver, 86% lead 80% copper 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.

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.

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

supervision of the exploration on the Cerro Las Minitas Project and for the preparation of the technical information in this

disclosure.
