San Jose Mine, Mexico

The San Jose Mine produced 1,917,540 ounces of silver and 11,425 ounces of gold in the third quarter of 2020 with average head grades for silver and gold of 254 g/t and 1.52 g/t, respectively. Silver and gold production for the first nine months of 2020 totaled 4.5 million ounces of silver and 27,710 ounces of gold.

Despite a minor decrease in mined tonnage, silver and gold production increased in the third quarter of 2020 compared to the same period in 2019 due to better grades encountered in the peripheral low-grade areas of the mine.

Caylloma Mine, Peru

In the third quarter of 2020, the Caylloma Mine produced 210,206 ounces of silver with an average head grade of 74 g/t. Silver production for the first nine months of 2020 totaled 704,190 ounces.

Gold production was 1,366 ounces with an average head grade of 0.60 g/t. The increase in production is due to higher head grades encountered in some of the production levels in the Animas vein. Gold production for the first nine months of 2020 totaled 2,282 ounces.

Lead and zinc production was 6,702,053 pounds and 10,313,225 pounds with average head grades for lead and zinc of 3.15% and 4.93%, respectively. Lead and zinc production was impacted in the quarter by a voluntary suspension of operations in July 2020 to disinfect and sanitize the mine site (refer to Fortuna news release dated July 28, 2020 ) and was partially offset by higher grades encountered in production stopes. Base metal production for the first nine months of 2020 totaled 33,111,227 pounds of zinc and 21,201,856 pounds of lead.

Lindero Pro   j   ect, Argentina

In the third quarter of 2020, a total of 675,000 tonnes of ore have been placed on the leach pad averaging 0.83 g/t gold, containing an estimated 17,980 ounces of gold. Average gold head grade of ore placed on the leach pad is below budget of 1.00 g/t to 1.10 g/t (refer to Fortuna news release dated May 8, 2020 ). The lower average head grade is due to COVID-19 related restrictions which delayed the start of mining activities and limited the access to high-grade ore from the pit and resulted in the shortfall being sourced from the medium grade stockpile.

The table below details material movements from the pit as estimated from the grade control model versus the Mineral Reserve block model for the third quarter of 2020. Reconciliation of the estimates indicate a good correlation with differences of less than five percent for all parameters. Management considers the result to be very encouraging when considering the variation in data density between the models.

<sup>Notes:
1. Grade control model numbers are based on estimates from blast holes.
2. Mineral Reserve model numbers are based on the Mineral Reserve estimates as of March 31, 2019 (refer to Fortuna news release dated April 4, 2019 ). See also 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. The updated Mineral Reserve estimate does not materially change the information presented in the Technical Report.
3. Based on a gold cut-off grade of 0.27 g/t.</sup>

From the commencement of mining operations in September 2019 (see Fortuna news release dated September 13, 2019 ) to the end of the third quarter 2020, a total of 2.3 million tonnes of mineralized material averaging 0.61 g/t Au, containing 45,700 ounces of gold has been extracted from the pit. Of this amount, 1.6 million tonnes averaging 0.52 g/t Au, containing an estimated 27,500 ounces of gold has been stockpiled, with the remaining 682,000 tonnes averaging 0.83 g/t Au, containing 18,200 ounces sent to the crushers.

Commissioning of the ADR plant was completed according to plan. The carbon columns' system is performing as per design capacity generating enriched carbon which is ready for the first gold pour in the upcoming days.

Quality Assurance & Quality Control

Grade control estimates are based on blast hole chip samples submitted to Lindero's on-site laboratory for preparation and assaying for gold, using fire assay with an atomic absorption finish. 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 submission of duplicate samples for verification of sampling and assay precision levels by an ISO 9001:2000 certified umpire laboratory. ALS Global Laboratory in Mendoza, Argentina prepared the samples for assaying and then forwarded the samples to ALS Global Laboratory in Lima, Peru for assay by standard fire assay methods.

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 this 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, mineralization 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. While the SEC recognizes the reporting of mineral deposits which do not meet the Industry Standard Guide 7 definition of "reserve" as of February 25, 2019, the effective adoption of the Modernization of Property Disclosures for Mining Registrants, such rules are not required to be compiled with until the first fiscal year beginning on or 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 descriptions 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 release may not be comparable with information made public by companies that report in accordance with U.S. standards.
