CAUTIONARY STATEMENT ON FORWARD LOOKING STATEMENTS / NON-GAAP FINANCIAL MEASURES

This corporate presentation contains forward looking statements which constitute “forward looking information” within the meaning of applicable Canadian securities legislation and “forward looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 (collectively, “Forward looking Statements”). All statements included herein, other than statements of historical fact, are Forward looking Statements and are subject to a variety of known and unknown risks and uncertainties which could cause actual events or results to differ materially from those reflected in the Forward looking Statements. The Forward looking Statements in this corporate presentation may include, without limitation, statements about the company’s plans for its mines and mineral properties including the construction and development of the Lindero Project; the company’s business strategy, plans and outlook; the merit of the company’s mines and mineral properties; mineral resource and reserve estimates; timelines; the future financial or operating performance of the company; expenditures; approvals and other matters. Often, but not always, these Forward looking Statements can be identified by the use of words such as “estimate”, “estimated”, “potential”, “open”, “future”, “assumed”, “projected”, “calculated”, “used”, “detailed”, “has been”, “gain”, “upgraded”, “expected”, “offset”, “limited”, “contained”, “reflecting”, “containing”, “conduct”, “increasing”, “remaining”, “to be”, “periodically”, or statements that events, “could” or “should” occur or be achieved and similar expressions, including negative variations.

Forward-looking Statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the company to be materially different from any results, performance or achievements expressed or implied by the Forward-looking Statements. Such uncertainties and factors include, among others, changes in general economic conditions and financial markets; changes in prices for silver and other metals; technological and operational hazards in Fortuna’s mining and mine development activities; risks inherent in mineral exploration; uncertainties inherent in the estimation of mineral reserves, mineral resources, and metal recoveries; construction delays, the timing and availability of financing; governmental and other approvals; political unrest or instability in countries where Fortuna is active; labor relations issues; as well as those factors discussed under “Risk Factors” in the Company's Annual Information Form. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in Forward-looking Statements, there may be other factors that cause actions, events or results to differ from those anticipated, estimated or intended.

Forward-looking Statements contained herein are based on the assumptions, beliefs, expectations and opinions of management, including but not limited to estimates of future production levels; expectations regarding mine production costs; expectations regarding mine construction costs; expected trends in mineral prices and currency exchange rates; the accuracy of the company’s current mineral resource and reserve estimates; that the company’s activities will be in accordance with the company’s public statements and stated goals; that there will be no material adverse change affecting the company or its properties; that all required approvals will be obtained; that there will be no significant disruptions affecting operations, including the construction of the Lindero Mine, and such other assumptions as set out herein. Forward-looking Statements are made as of the date hereof and the Company disclaims any obligation to update any Forward-looking Statements, whether as a result of new information, future events or results or otherwise, except as required by law. There can be no assurance that Forward-looking Statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, investors should not place undue reliance on Forward-looking Statements.

This corporate presentation also refers to non-GAAP financial measures, such as cash cost per tonne of processed ore; cash cost per payable ounce of silver; total production cost per tonne; all-in sustaining cash cost; all-in cash cost; adjusted net (loss) income; operating cash flow per share before changes in working capital, free cash flow, income taxes, and interest income; and adjusted EBITDA. These measures do not have a standardized meaning or method of calculation, even though the descriptions of such measures may be similar. These performance measures have no meaning under International Financial Reporting Standards (IFRS) and therefore, amounts presented may not be comparable to similar data presented by other mining companies.

LINDERO PROJECT, ARGENTINA

• As of the end of September, the Company has assigned, mainly through purchase order/construction contracts, ~$154 million or 82% of the project’s total direct capital cost

• As of the end of October, the project has advanced 26% towards completion of construction

• The initial capital cost of the project is currently forecast to increase between 10% and 14%, the increment is mainly driven by the impact of higher headcount in indirect costs and higher owner’s cost. Forecast excludes savings from local currency devaluation against the US Dollar

• As of the end of September, total cash spent on construction at Lindero in 2018 amounted to approximately $66.8 million, with $32.2 million spent in the third quarter

• The HPGR1 and the primary crusher are expected to arrive on site by December; the following mining equipment has either arrived on site or is expected to arrive in November: three dozers, two graders, six 100-ton trucks, one hydraulic excavator, two 17-cubic yard wheel loaders, and two mine production drill rigs

Brownfields Exploration: Arizaro Gold-copper Porphyry System

Notes: 1. Source of historical resource: “Technical Report Update on the Lindero Heap Leach Project” prepared by Kappes, Cassiday & Associates for Goldrock Mines Corp. Technical report effective date of

January 2, 2016. Historical Mineral Resource reported as of July 1, 2013 2. In the opinion of Fortuna, although mineralization is present at Arizaro, the geology is insufficiently understood to allow the estimate of reliable Mineral Resources at this time and the historical

estimates should not be relied upon 3. The Arizaro historical resource was reported fully diluted to 8m by 8m by 8m blocks at a cut-off grade of 0.2 g/t Au. The source of the historical resource states that reasonable metal prices and

extraction costs and recoveries, in a general sense, were considered during estimation and then factored down to account for that material which would become ore using internal cut-offs. In consideration of the depth limits of any potential open pit mining, the Arizaro historical resource was limited to a bottom elevation of 3,850 meters, approximately 300 meters below the general surface

4. The historical resource estimate uses categories as set out in NI 43-101 5. There has been no further Mineral Resource estimates conducted at Arizaro since July 1, 2013 6. Additional drilling has been conducted at Arizaro in 2018 to improve the understanding of geologic controls on mineralization and verify assumptions used in the estimation of the historical estimate,

with the ultimate goal of re-estimating the Arizaro Mineral Resources to make current. There can be no assurance that the historical Mineral Resource estimate will be updated. 7. A Qualified Person has not done sufficient work to classify the historical estimate as a current Mineral Resource 8. Fortuna Silver Mines Inc. is not treating the historical estimate as a current Mineral Resource 9. Refer to slide 40 for Arizaro historic drill highlights

Animas NE Vein Step-out Drilling Assay Results for Principal Mineralized Intervals

APPENDIX

Quality Assurance & Quality Control Drilling is carried out using HQ and NQ size tooling. 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 Lima, Peru. Sample size ranges between 2 kilograms to 9 kilograms. The remaining half core is retained on-site for verification and reference purposes. Following preparation, the samples are assayed for gold and silver by standard fire assay methods and for silver and base metals by ICP and atomic absorption methods utilizing aqua regia digestion. The QA-QC program includes the blind insertion of certified reference standards and assay blanks at a frequency of approximately 1 per 15 normal samples as well as the inclusion of duplicate samples for verification of sampling and assay precision levels.

Qualified Person David F. Volkert, Vice President of Exploration for Fortuna Silver Mines Inc., is a Qualified Person as defined by National Instrument 43-101 being a member of the Association of Professional Engineers and Geoscientists of British Columbia (P.
