Notes to the above mineral reserves and resources:
  1. Effective December 31, 2017.
  2. Assumed metal prices for estimated Mineral Reserves were $17.50 per ounce of silver and $1,250 per ounce of gold.
  3. Assumed metal prices for estimated Mineral Resources were $20.00 per ounce of silver, $1,400 per ounce of gold, $1.15 per pound Zinc and $1.00 per pound Lead.
  4. Mineral Resources are in addition to Mineral Reserves and do not have demonstrated economic viability. Inferred Mineral Resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be considered for estimation of Mineral Reserves, and there is no certainty that the Inferred Mineral Resources will be realized.
  5. Rounding of tons and ounces, as required by reporting guidelines, may result in apparent differences between tons, grade, and contained metal content.
  6. For details on the estimation of mineral resources and reserves, including the key assumptions, parameters and methods used to estimate the Mineral Resources and Mineral Reserves, Canadian investors should refer to the NI 43-101 Technical Reports for Coeur's properties on file at www.sedar.com.
