Corporate Updates

Fortuna reports updated first year gold doré production plan for the Lindero

Project, Argentina

Vancouver, April 4, 2019-- Fortuna Silver Mines, Inc. (NYSE: FSM ) (TSX: FVI) is pleased to provide its

updated estimated gold dor é production plan for the first year of commercial production and an

updated Mineral Reserve and Mineral Resource estimate as of March 31, 2019 for the Lindero Project

located in Argentina.

Jorge A. Ganoza, President and CEO, commented , “Based on the results of the 2018 infill drill program

and optimization of our mine plan , we have been able to identify higher grade mineralized areas for

mining in Lindero´s first year of commercial production .” Mr. Ganoza added, “ As we conduct a dditional

studies on expanding the leach pad facility , the Company will be in a position to assess the ability to

upgrade material from measured and indicated resources to reserves.”

Highlights of Update

• Gold dor é production in the first year of commercial production is estimated to be between

145,000 and 160,000 ounces

• Combined Proven and Probable Mineral Reserves are reported at 84.2 Mt containing 1.7 Moz of

gold, representing a decrease of 5 percent in tonnes and 2 percent in contained gold ounces

• Combined Measured and Indic ated Mineral Resources exclusive of Mineral Reserves are

reported at 18.9 Mt containing 302 ,000 ounces of gold, representing an increase of 51 percent

in tonnes and 211 percent in contained gold ounces

• Inferred Mineral Resources exclusive of Mineral Reserves are reported at 8.6 Mt containing

106,000 ounces of gold, representing an increase of 51 percent in tonnes and 63 percent in

contained gold ounces

Mineral Reserves and Mineral Resources

Mineral Reserves and Mineral Resources are reported as of March 31, 2019 based on 212 diamond drill

holes totaling 44,550 meters. The estimates incorporate an updated geological interpretation based on

the infill drilling conducted in 2018 (see Fortuna news release dated September 6, 2018), updated metal

prices and estimated operating costs. The updated technical information does not materially change the

information presented in the Technical Report entitled “Fortuna Silver Mines Inc.: Lindero Property,

Salta Province, Argentina”, with an effective date of October 31, 2017 prepared by Eric Chapman, Edwin

Gutierrez, Geoff Allard, and Denys Parra Murrugarra (“Technical Report”).

Mineral Resource estimation involved the usage of drill hole samples in conjunction with surface

mapping to construct three -dimensional wireframes defining lithologic, alteration, and grade domains.

Samples were selected inside these wireframes, coded, com posited and top cut. Boundaries were

-2-

treated as hard, firm or soft based on statistical and geostatistical analysis. Gold and copper grades were

estimated by ordinary kriging into a geological block model consisting of 10 m eter x 10 meter x 4 meter

selective mining units representing each domain. Estimated grades were validated globally, locally, and

visually prior to classification and are reported above a 0.20 g/t Au cut -off grade within a conceptual pit

shell.

The update d Mineral Resource and Mineral Res erve estimates use the same methodology (key

assumptions, parameters and methods) as the Technical Report which is available on the Company’s

website, on SEDAR , and on the SEC’s website . However, Mineral Reserve estimates have been

conducted taking into account the new updated resource block model, revised cost estimates, metal

prices, projected exchange rates, and the updated detailed design capacity of the leach pad. Mineralized

material inside the ultimate pit shell that cannot be accommodated by the updated leach pad design has

been classified as a Mineral Resource.

Notes:

1. Mineral Reserves and Resources are as defined by the 2014 CIM Definition Standards for Mineral Resources and Mineral

Reserves

2. Mineral Resources are exclusive of Mineral Reserves

3. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability

4. Factors that could materially affect the reported Mineral Resources or Mineral Reserves include; changes in metal price and

exchange rate assumptions; changes in local interpretations of mineralization; changes to assumed metallurgical recoveries,

mining dilution and recovery; and assumptions as to the continued ability to acc ess the site, retain mineral and surface rights

titles, maintain environmental and other regulatory permits, and maintain the social license to operate

5. Mineral Resources and Mineral Reserves for Lindero are reported as of March 31, 2019

6. Mineral Reserves for Lindero are reported based on open pit mining within designed pit shells based on variable gold cut -off

grades and gold recoveries by metallurgical type. Met type 1 cut -off 0.27 g/t Au, recovery 75.4%; Met type 2 cut -off 0.26 g/t

Au, recovery 78.2%; Met type 3 cut -off 0.26 g/t Au, recovery 78.5%; and Met type 4 cut -off 0.30 g/t Au, recovery 68.5%. The

cut-off grades and pit designs are considered appropriate for long term gold prices of $1, 320/oz. Mineral Reserves are

restricted to leach pad design capacity. Assumptions used in the pit design are the same as those for the Mineral Resources

7. Lindero Mineral Resources are reported within a conceptual pit shell above a 0.2 g/t Au cut -off grade using a long- term gold

price of $1, 320/oz, mining costs at $1. 28 per tonne of material, with total processing and process G&A costs of $ 8.29 per

tonne of ore and an average process recovery of 75%. The refinery costs net of pay factor were estimated to be $6.90 per

ounce of gold. Slope angles are b ased on 3 sectors (39°, 42°, and 47°) consistent with geotechnical consultant

recommendations

First year production plan

For the first year of commercial production, Lindero´s mine plan has been optimized so that the

operation will benefit from mining the higher grade mineralization outcropping that was identified

through the infill drilling completed in 2018. As a result, g old doré production for Lindero’s first year of

commercial production is estimated to be between 145,000 ounces and 160,000 ounces and is based on

the factors set out in the Technical Report.

Cautionary Note to United States Investors Concerning Estimates of Reserves and Resources

Reserve and resource estimates included in this news release have been prepared in accordance with National

Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43 -101") and the Canadian Institute of Mining,

Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral Reserves. NI 43 -101 is a rule

developed by the Canadian Securities Administrators that establishes standards for public disclosure by a Canadian

company of scientific and technical information concerning mineral projects. Equivalent U.S. reporting

requirements are currently governed by the United States Securities and Exchange Commission ("SEC") Industry

Guide 7 (“Industry Guide 7”) under the U.S. Securities Act of 1933, as amended. Canadian standards, including NI

43-101, differ significantly from the requirements of the SEC currently in effect under Industry Guide 7, and reserve

and resource information contained in t his news release may not be comparable to similar information disclosed by

U.S. companies. In particular, the term "resource" does not equate to the term "reserves". Under the SEC's

disclosure standards currently in effect under Industry Guide 7, mineraliz ation may not be classified as a "reserve"

unless the determination has been made that the mineralization could be economically and legally produced or

extracted at the time the reserve determination is made. The SEC has not recognized the reporting of mineral

deposits which do not meet the Industry Guide 7 definition of “reserve” prior to the adoption of the Modernization

of Property Disclosures for Mining Registrants, which rules will be required to be complied with in the first fiscal

year beginning on o r after January 1, 2021. As a result, the SEC's disclosure standards currently in effect normally

do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources"

or "inferred mineral resources" or other des criptions of the amount of mineralization in mineral deposits that do

not constitute "reserves" by U.S. standards in documents filed with the SEC. You are cautioned not to assume that

resources will ever be converted into reserves. You should also understand that "inferred mineral resources" have a

great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility.

You should also not assume that all or any part of an "inferred mineral resource" will ever be upgraded to a higher

category. Under Canadian rules, estimated "inferred mineral resources" may not form the basis of feasibility or pre-

feasibility studies except in rare cases. You are cautioned not to assume that all or any part of an "inferred mineral

resource" exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted

disclosure under Canadian regulations; however, the SEC's disclosure standards currently in effect under Industry

Guide 7 normally only permit issuers to report mineralization that does not constitute "reserves" by such standards

as in-place tonnage and grade without reference to unit measures. The requirements of NI 43 -101 for identification

of "reserves" are also not the same as those of the SEC's disclosure standards currently in effect under Industry

Guide 7, and reserves reported in compliance with NI 43 -101 may not qualify as "reserves" under such SEC

standards. Accordingly, information concerning mineral deposits set forth in this news r elease may not be

comparable with information made public by companies that report in accordance with U.S. standards.
