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. Lindero 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 Lindero are reported based on open pit mining within designed pit shells based on variable gold cut-off grades and gold recoveries by metallurgical type. Met type 1 cut-off 0.27 g/t Au, recovery 75.4%; Met type 2 cut-off 0.26 g/t Au, recovery 78.2%; Met type 3 cut-off 0.26 g/t Au, recovery 78.5%; and Met type 4 cut-off 0.27 g/t Au, recovery 68.5%. The cut-off grades and pit designs are considered appropriate for long term gold prices of US$1,600/oz. Assumptions used in the pit design are the same as those for resources. Mineral Reserves are restricted to a maximum heap leach capacity of 84.2 Mt and Proven Reserves include 2.6 Mt of stockpiled material averaging 0.55 g/t Au
  7. Mineral Reserves for Lindero are reported based on open pit mining within a designed pit shell based on variable gold cut-off grades and gold recoveries by metallurgical type. Met type 1 cut-off 0.27 g/t Au, recovery 75.4%; Met type 2 cut-off 0.26 g/t Au, recovery 78.2%; Met type 3 cut-off 0.26 g/t Au, recovery 78.5%; and Met type 4 cut-off 0.27 g/t Au, recovery 68.5%. Mining recovery is estimated to average 100% and mining dilution 0%. The cut-off grades and pit designs are considered appropriate for long term gold prices of US$1,600/oz, estimated mining costs of US$1.11 per tonne of material, total processing and process G&A costs of US$6.21 per tonne of ore, and refinery costs net of pay factor of US$6.50 per ounce gold. Lindero Mineral Reserves are restricted to a maximum heap leach capacity of 84.2 Mt. Reported Proven Reserves include 2.6 Mt averaging 0.55 g/t Au of stockpiled material. Lindero Mineral Resources are reported within the same conceptual pit shell above a 0.2 g/t Au cut-off grade based on the same parameters used for Mineral Reserves and a 15% upside in metal prices
