• Six months from closing: US$2.0M in cash and US$2.0M* in shares (based on the greater of the prior 20-day VWAP and the DMP).
• 12 months from closing: US$2.0M in cash and US$2.0M* in shares (based on the greater of the prior 20-day VWAP and the DMP).

* The Company has the option to pay all cash in lieu of shares. Any shares issued will be subject to applicable Canadian and US resale restrictions.

To secure payments under the Agreement, the Company has agreed to pledge to Electrum the shares representing Electrum's 60% indirect working interest in the CLM Project.

Because of Electrum's current shareholdings in the Company, the purchase of Electrum's 60% indirect working interest in the CLM Project is a related party transaction under Multilateral Instrument 61-101. The Agreement is subject to regulatory approval and other closing conditions, including shareholder approval.

The Company, in seeking both TSX Venture Exchange and shareholder approvals, will convene an extraordinary shareholders meeting to be held in conjunction with an Annual General Meeting on or about September 4, 2020.

Through the transaction, Southern Silver will acquire an additional 49.9 million ounces silver and 1.35 billion pounds of combined lead and zinc to its account based on the current National Instrument 43-101 Mineral Resources estimate of the CLM Project. Additionally, Southern Silver will become more attractive on a corporate level with the Company's market profile being enhanced by having ownership of one of the larger and highest grade, undeveloped silver projects in the world.

Lawrence Page, Q.C., Southern Silver's Chairman and Director, stated: "Upon completion of the transaction the benefits to Southern Silvers shareholders and investors will be significant. Sole ownership of the Project inclusive of the significant resources developed to date allows us great latitude in developing the Project for substantial resource growth. The transaction will also provide a 150% increase in attributable resources which will be highly accretive to Southern Silver shareholders."

Warrant Exercise

Electrum Global Holdings L.P. has exercised 9.0 million share purchase warrants at C$0.15 for gross proceeds to the Company of C$1,350,000. The Company utilized such funds in the payment of a deposit on execution of the Agreement, which deposit will be credited to the US$2 million payment in shares on closing of the Agreement.

Cerro Las Minitas Project

The Cerro Las Minitas project is an advanced exploration stage polymetallic Ag-Pb-Zn-Cu Skarn/CRD project located in southern Durango, Mexico.

The Cerro Las Minitas project as of May 9^th, 2019 contains a Mineral Resource Estimate, at a 175g/t AgEq cut-off, of⁽¹⁾

• Indicated - 134Moz AgEq: 37.5Moz Ag, 40Mlb Cu, 303Mlb Pb and 897Mlb Zn
• Inferred - 138Moz AgEq: 45.7Moz Ag, 76Mlb Cu, 253Mlb Pb and 796Mlb Zn

A total of 133 drill holes for 59,000 metres have now been completed on the CLM Project with exploration expenditures of approximately US$18.5 million equating to exploration discovery costs of approximately C$0.07 per AgEq ounce to the end of 2019.

Southern Silver has identified a further 10,000 metres in exploration drilling for 2020, targeting specific step-outs from strongly silver-enriched mineral intercepts in the Las Victorias, South Skarn and the Mina La Bocona targets. The targeting is designed to increase the current mineral resource estimate by approximately 30%. The CLM Project remains one of the larger undeveloped silver-lead-zinc projects in the world. It is fully permitted to continue exploration on the property, with a strong potential resource growth profile.

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. Our property portfolio also includes the Oro porphyry copper-gold project located in southern New Mexico, USA.

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.
