Notes to above Mineral Reserves and Resources:

  1. The qualified person for Mineral Reserve and Mineral Resources estimates is Christopher Pascoe, Coeur's Director, Technical Services.
  2. Mineral Reserve and Mineral Resource estimates are effective December 31, 2020.
  3. Assumed metal prices for estimated Mineral Reserves were $1,400 per ounce of gold, $17.00 per ounce of silver, $1.15 per pound of zinc, $0.95 per pound of lead.
  4. Assumed metal prices for estimated Mineral Resources were $1,600 per ounce of gold, $20.00 per ounce of silver, $1.30 per pound of zinc, $1.00 per pound of lead, except Lincoln Hill and Wilco at $1,350 per ounce of gold and $22.00 per ounce of silver, and La Preciosa at $1,500 per ounce of gold and $20.00 per ounce of silver.
  5. 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.
  6. Rounding of tons and ounces, as required by reporting guidelines, may result in apparent differences between tons, grade, and contained metal content.
  7. Excludes the impact of the gold stream agreement at Palmarejo.
  8. 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.
