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. San Jose Mineral Resources and Reserves are estimated as of June 30, 2020 and reported as of December 31, 2020 taking into account production-related depletion for the period through December 31, 2020
  6. Mineral Reserves for the San Jose Mine are based on underground mining within optimized stope designs using an estimated NSR break-even cut-off grade of US$69.47/t, equivalent to 120 g/t Ag Eq based on assumed metal prices of US$21/oz Ag and US$1,600/oz Au; estimated metallurgical recovery rates of 91% for Ag and 90% for Au and mining costs of US$34.92/t; processing costs of US$17.10/t; and other costs including distribution, management, community support and general service costs of US$17.44/t based on actual operating costs. Mining recovery is estimated to average 93% and mining dilution 11%. Mineral Resources are reported at a 100 g/t Ag Eq cut-off grade based on the same parameters used for Mineral Reserves and a 15% upside in metal prices. Proven + Probable Reserves include 1.9 Mt containing 14 Moz of silver and 83 koz of gold reported at a 123 g/t Ag Eq cut-off grade and Inferred Resources totaling 2.5 Mt containing 9.7 Moz of silver and 70 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. Eric 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.
