Notes:

  1. Mineral Reserves and Mineral 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 access 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 are estimated as of June 30, 2018 and reported as of December 31, 2018 taking into account production-related depletion through December 31, 2018. Refer to technical report titled “Fortuna Silver Mines Inc.: San Jose Mine, Oaxaca, Mexico” with an effective date of February 22, 2019 prepared by Eric Chapman, P.Geo. and Amri Sinuhaji, P.Eng.
  6. Mineral Reserves for the San Jose Mine are estimated using an NSR break-even cut-off grade of US$65.90/t, equivalent to 131 g/t Ag Eq based on assumed metal prices of US$18.25/oz Ag and US$1,320/oz Au; estimated metallurgical recovery rates of 92 % for Ag and 91 % for Au and mining costs of US$31.48/t; processing costs of US$16.55/t; and other costs including distribution, management, community support and general service costs of US$17.91/t based on actual operating costs. Mining recovery is estimated to average 89% and mining dilution 12%. Mineral Resources are estimated at a 100 g/t Ag Eq cut-off grade using the same metal prices and metallurgical recoveries as for Mineral Reserves and a mine to mill operating cost of US$52.50/t. Proven and Probable Mineral Reserves include 3.20 Mt containing 26.9 Moz of silver and 164 koz of gold reported at a 134 g/t Ag Eq cut-off grade, in addition to Inferred Resources totaling 1.32 Mt containing 7.1 Moz of silver and 49 koz of gold reported at a 100 g/t Ag Eq cut-off grade, located in the Taviche Oeste concession and subject to a 2.5 % royalty
  7. EEric Chapman, P. Geo. (APEGBC #36328) is the Qualified Person for resources and Amri Sinuhaji (APEGBC #48305) is the Qualified Person for reserves, both being employees of Fortuna Silver Mines Inc.
