Coeur Reports Significant Increase In Mineral Reserves At Rochester

Coeur Mining, Inc. (“Coeur” or the “Company”) (NYSE: CDE) (TSX: CDM) announced contained ounces of proven and probable reserves totaling approximately 86.0 million silver ounces and 605,000 gold ounces, representing increases of 91.5% and 96.4%, respectively, at its Rochester mine in Nevada. In addition to these reserves, Coeur estimates that effective as of September 16, 2013, Rochester contains approximately 69.3 million silver ounces and 560,000 gold ounces of measured and indicated resources and approximately 26.2 million silver ounces and 105,000 gold ounces of inferred resources. The resource estimates do not reflect results from the ongoing 2013 drilling program.

  1. Effective as of September 16, 2013 using metal prices of $25.00 per silver ounce and $1,450 per gold ounce and year-end 2012 topography and parameters (other than the lower metals price assumptions and the impact of the previously-announced resolution of the claims dispute). The reserves do not reflect 2013 mine production, depletion of reserves or exploration or drilling conducted during 2013. Rounding of tons and ounces, as required by reporting guidelines, may result in apparent differences between tons, grade, and contained metal content.

Mitchell J. Krebs, Coeur’s President and Chief Executive Officer, said, “Resolving the mining claims dispute at Rochester in late June enabled us to develop a new mine plan for Rochester, which significantly increased our silver and gold reserves. Based on this work, we now have a higher level of confidence in the long-term profile of Rochester, which we believe will extend well past the life of the current reserves. We expect to further increase in-situ and stockpile reserves and resources at Rochester at year end as a result of our 2013 drilling program. Rochester represents a unique and attractive source of growth for our stockholders with relatively minimal capital requirements, high expected returns, an attractive jurisdiction, and lower execution risk given its operating history of more than 25 years.”

Operating Outlook

Rochester’s annual crushing rate in 2012 was approximately 9.0 million tons, which resulted in production of 2.8 million silver ounces and 38,066 gold ounces. In 2013, the Company expects to crush approximately 12 million tons at Rochester. Annual crushing rates are expected to ramp up to 13 - 16.5 million tons starting in 2014. Beyond 2017, the Company anticipates increasing annual crushing rates to approximately 18.5 million tons.

Recent investments in the existing heap leach pads at Rochester have increased total capacity by 72 million tons, which Coeur expects will enable operations to continue into the second half of 2017. The removal of the claims dispute constraints allowed Coeur to reevaluate pit and pad limits and plan for new leach pad capacity. The Company is in the process of obtaining permits for 120 million tons of additional pad capacity, which are expected to be received by mid-2016. This expanded capacity is anticipated to further extend Rochester’s active mine life based on existing reserves through at least 2023. The Company is also assessing the optimal scenario for a further expansion of Rochester, targeting opportunities to expand reserves from the Company’s significant additional mineral resources.

The increased reserves at Rochester are inside pit limits now fully contained within the Company’s land package of approximately 8,800 acres of U.S. federal unpatented claims, patented claims, and other rights. The Company is in the process of preparing a new Technical Report pursuant to Canadian National Instrument 43-101 (“NI 43-101”) to document the changes to the reserves and resources at Rochester that will be filed on SEDAR within 45 days.

Notes to the above mineral reserves and resources:
  1. Effective December 31, 2012, except for La Preciosa, which is effective June 26, 2013, and the Rochester update described herein, which is effective September 16, 2013 but based on year-end 2012 topography and parameters (other than the claims dispute and metals prices). The reserves do not reflect 2013 mine production depletion of the reserves or exploration or drilling conducted during 2013. Rounding of tons and ounces, as required by reporting guidelines, may result in apparent differences between tons, grade, and contained metal content.
  2. Metal prices used for mineral reserves were $27.50 per ounce of silver and $1,450 per ounce of gold, except Endeavor, at $2,200 per metric ton of lead, $2,200 per metric ton of zinc and $34.00 per ounce of silver and Rochester, at $25.00 per ounce of silver and $1,450 per ounce of gold. Metal prices used for mineral resources were $33.00 per ounce of silver and $1,700 per ounce of gold, except for La Preciosa (see note 7 below), and Endeavor, at $2,200 per metric ton of lead, $2,200 per metric ton of zinc and $34.00 per ounce of silver.
  3. Palmarejo mineral resources are the addition of Palmarejo, Guadalupe, and La Patria (measured, indicated, and inferred).
  4. Mineral resources are in addition to mineral reserves and have not 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.
  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 for each property, please refer to the relevant NI 43-101-compliant Technical Report on file at www.sedar.com and the updated Technical Report for Rochester to be filed within 45 days on www.sedar.com.
  7. La Preciosa mineral resources are effective June 26, 2013. La Preciosa mineral resources’ prices used were $27.45 per silver ounce and $1,508 per gold ounce. There are no mineral reserves at La Preciosa. The NI 43-101-compliant Technical Report, disclosing results of the PEA, is available on www.sedar.com.
