Fortuna updates on infill drill program at the Lindero gold Project in Argentina

Vancouver, September 6, 2018 -- Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) is pleased to provide

results for its infill drilling program at the Lindero Project in Argentina. The Lindero P roject is under

construction, and commercial operations are planned to start late in the third quarter of 2019, with an

estimated gold production of 1 37,000 ounces of gold in the first full year of operatio n (Please refer to

the Lindero Project Technical report dated October 31, 2017).

Eric Chapman, Vice President of Technical Services, commented: "Infill drilling has been carried out with

the express intention of improving the confidence in the estimated tonnes and grade of material

planned for mining in year one at Lindero . The mineralized intercepts encountered have met or

exceeded our expectations in 44 of the 61 holes drilled when compared to estimated block model gold

grades as of September 9, 2017." Mr. Chapman continued, "Of particular interest are the results for drill

holes LDH-138, LDH-139, and LDH-164 associated with the mingled diorite porphyry unit in the center of

the deposit, in an area which was previously thought to be non -mineralized. The new drilling results are

presently being incorporated into an updated internal estimate of Mineral Resources and Re serves with

the intention of optimizing the mine plan to capture the benefits of these new results. Such updated

technical information will not materially change the existing Mineral Resources estimates."

The infill d rilling program, consisting of 61 diamond drill holes totaling 1,952 meters, focused on the

areas planned for mining at Lindero in year one with holes ranging from 12 m eters to 68 m eters in

length. The program was designed with three objectives: to improve the estimation of grades in

mineralized areas with lower density of drilling ; to better define the contact between mineralized and

non-mineralized material at the periphery of the deposit and at the boundaries between lithologic units;

and to source fresh samples for complementary metallurgical column tests on Mineral R eserves

scheduled for year one. A map showing 2018 infill d rilling collar location and a longitudinal section

showing updated drilling and 2017 block model can be found at the fol lowing links, respectively:

Units associated with non-mineralization:

CPD2 = Crowded diorite porphyry 2

PMI = Post mineralized intrusive

S1 = Tertiary sedimentary rocks

Notes:

1. All holes drilled vertically

2. The Lindero Deposit is a gold-rich porphyry with mineralization permeating throughout the deposit, making the calculation of true

thickness impossible as no definitive across strike direction exists.

Quality Assurance & Quality Control

Following detailed geological and geotechnical logging, drill core samples are split on -site by diamond

sawing. One half of the core is submitted to the ALS Global Laboratory in Mendoza, Argentina for

preparation. The remaining half core is retained on -site for verification and reference purposes.

Following preparation, the samples are assayed in the ALS Global Laboratory in Lima, Peru for gold by

standard fire assay methods; for silver and base metals by ICP and atomic emission spectroscopy

methods utilizing four acid digestion; and for cyanide soluble copper by atomic absorption methods. The

QA-QC program includes the blind insertion of certified reference standards and assay blanks at a

frequency of approximately 1 per 20 normal samples as well as the in clusion of duplicate samples for

verification of sampling and assay precision levels.

About the Lindero gold Project

In September 2017, the commencement of construction at Lindero was officially launched (see Fortuna

news releases dated September 21, 2017 and December 21, 2017 ). Lindero has been designed as an

18,750 t onnes per day owner operated open pit mine with a pit life of 13 years based on existing

mineral reserves. The initial capital cost budget estimate for the construction of Lindero is US$239

million, forecast to increase between 10% and 17% (refer to Fortuna news release dated August 7, 2018,

“Fortuna provides construction update and reports initial on -site arrival of mine equipment at its

Lindero gold Project in Argentina”); this amount does not include VAT which is expected to be recovered

in the first 24 months from the start of mining operations. The technical report of the Lindero Project is

available on SEDAR at www.sedar.com and on the Company's website at

https://www.fortunasilver.com/site/assets/files/4098/lindero-project-technical-report-effective-date-
