Notes:

  1. Mineral Reserves and Mineral Resources are as defined by CIM Definition Standards on 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. There are no known legal, political, environmental, or other risks that could materially affect the potential development of the Mineral Resources or Mineral Reserves at San Jose
  5. Mineral Resources and Mineral Reserves are estimated as of June 30, 2017 and reported as of December 31, 2017 taking into account production-related depletion for the period through December 31, 2017
  6. Mineral Reserves for San Jose are estimated using a break-even cut-off grade of 117 Ag Eq g/t based on assumed metal prices of US$19/oz Ag and US$1,250/oz Au; estimated metallurgical recovery rates of 92% for Ag and 91% for Au and and actual operating costs. Mineral Resources are estimated at a 100 g/t Ag Eq cut-off grade with Ag Eq in g/t = Ag (g/t) + Au (g/t) * ((US$1,250/US$19) * (91/92)). Proven + Probable Reserves include 2.74 Mt containing 25.6 Moz of silver and 153 koz of gold reported at a 120 g/t Ag Eq cut-off grade and Inferred Resources totaling 1.36 Mt containing 11.3 Moz of silver and 62 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
