Coeur Reports Increases in Year-End 2017 Mineral Reserves and Resources

year-end 2017 contained reserves and resources from continuing operations¹,

which reflect significant increases compared to 2016 and demonstrate the

success of the Company’s expanded near-mine exploration program. Proven

and probable reserves of 335.8 million silver equivalent ounces (AgEqOz)²

are 10% higher, driven primarily by year-over-year silver equivalent²

reserve increases of 36% at Wharf and 17% at Palmarejo. Measured and

indicated resources of approximately 385.7 million AgEqOz²

and inferred resources of 171.0 million AgEqOz² represent

increases of 42% and 45%, respectively.

The Company’s year-end 2017 reserves assumed silver and gold prices of

$17.50 per ounce and $1,250 per ounce, respectively, unchanged from the

assumptions used to determine year-end 2016 and 2015 reserves.

Highlights

• 
  New discoveries boost Palmarejo’s reserves and resources –
  Contained silver and gold reserves increased 15% to 47.0 million and
  19% to 706,000 ounces, respectively, compared to the prior year. This
  was primarily attributable to an initial reserve estimate at the
  Nación-Dana deposit, for which preliminary mine planning is underway.
  The Company’s 2017 drill program contributed to 56% higher measured
  and indicated resources compared to 2016 and produced initial inferred
  resource estimates for the La Bavisa and Zapata veins. These, along
  with several additional veins discovered in the past 18 months, drove
  a 48% increase in inferred resources, demonstrating significant
  potential for continued resource growth
  


• 
  Wharf delivers 36% increase in gold reserves – Year-end 2017
  reserves totaled 869,000 ounces compared to 639,000 ounces the prior
  year. Wharf’s current gold reserves are also 55% higher than the
  560,000 ounces at year-end 2013, the last reported reserve figure
  prior to Coeur’s acquisition, despite depletion in the intervening
  years of approximately 100,000 contained ounces by Goldcorp in 2014
  and early 2015 and approximately 335,000 contained ounces by Coeur
  


• 
  Modest reserve gains at Kensington and Rochester; significant
  increases to Rochester resources– Proven and probable gold
  reserves at Kensington increased 5% to 520,000 ounces. At Rochester,
  proven and probable AgEqOz² reserves increased
  approximately 2%, while measured and indicated resources increased 71%
  and inferred resources increased 56%. The Company anticipates
  publishing an updated technical report for Kensington later in the
  first quarter, reflecting Jualin’s 2017 exploration results
  

• 
  2017 year-end resources reflect addition of high-grade Silvertip
  mineralization – Silvertip had measured and indicated resources of
  73.3 million AgEqOz² and inferred resources of 14.1 million
  AgEqOz², accounting for approximately 19% and 8%,
  respectively, of companywide totals. An aggressive campaign of both
  surface and underground exploration drilling commenced at Silvertip
  during the fourth quarter and the Company remains focused on producing
  an initial reserve estimate for inclusion in the technical report
  anticipated later this year
  

“Over the last 18 months, we have invested heavily in near-mine

exploration, which we believe offers the best risk-weighted returns to

stockholders. Our mines have been historically under-drilled, yet

present significant exploration potential as evidenced by the number of

new discoveries at Palmarejo,” said Mitchell J. Krebs, Coeur’s President

and Chief Executive Officer.

“We expect to sustain an elevated level of exploration investment in

2018 given the success our expanded programs are generating. Our 2018

programs reflect a higher proportion of capitalized drilling versus

expensed exploration. Our top priorities will remain Palmarejo,

Kensington and now Silvertip. Drilling at Palmarejo will focus on

expansion of the Nación-Dana deposit as well as delineation of several

recent discoveries where we can most effectively leverage existing

infrastructure. At Kensington, exploration efforts will target expansion

of Kensington Main and Raven, and at Silvertip, drilling will focus on

infill and expansion priorities to support our near- and medium-term

mine planning efforts.”

Christopher Pascoe, Coeur's Director, Technical Services and a qualified

person under Canadian National Instrument 43-101, reviewed and approved

the scientific and technical information concerning Coeur's mineral

projects in this news release. 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. For a

description of the key assumptions, parameters and methods used to

estimate mineral reserves and resources, as well as data verification

procedures and a general discussion of the extent to which the estimates

may be affected by any known environmental, permitting, legal, title,

taxation, socio-political, marketing or other relevant factors, Canadian

investors should see the Technical Reports for each of Coeur's

properties as filed on SEDAR at www.sedar.com.

Cautionary Note to U.S. Investors - The United States Securities and

Exchange Commission permits U.S. mining companies, in their filings with

the SEC, to disclose only those mineral deposits that a company can

economically and legally extract or produce. We may use certain terms in

public disclosures, such as "measured," "indicated," "inferred” and

“resources," that are recognized by Canadian regulations, but that SEC

guidelines generally prohibit U.S. registered companies from including

in their filings with the SEC. U.S. investors are urged to consider

closely the disclosure in our Form 10-K which may be secured from us, or

from the SEC's website at http://www.sec.gov.

Notes to 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

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.
   

Notes to above Mineral Reserves and Mineral Resources:

1. 
   Mineral Reserves and Mineral Resources estimate as reported by
   Goldcorp, Inc. (“Goldcorp”) in its Annual Information Form dated March
   31, 2014 ("AIF") for the financial year ended December 31, 2013,
   available to Canadian investors at www.sedar.com
   under Goldcorp's profile. As discussed in the AIF, Mineral Reserves
   and Mineral Resources were prepared by Goldcorp in accordance with NI
   43-101 under the supervision of a qualified person. Coeur is not
   treating these historical estimates as current and has not completed
   sufficient work to classify the historical estimate as current mineral
   reserves or mineral resources for Coeur’s purposes. Following Coeur's
   acquisition of Wharf, its qualified person reviewed and verified the
   scientific and technical information of Goldcorp as well as completed
   other work necessary for purposes of preparing a 43-101 technical
   report, including validation of data quality, resource model accuracy,
   and costs used in reserve and resource cutoffs.
   


2. 
   As discussed in the AIF, mineral reserves were calculated by Goldcorp
   using metal prices of $1,300 per gold ounce and $22 per silver ounce,
   and mineral resources were calculated using $1,500 per gold ounce and
   $24 per silver ounce. Mineral resources are in addition to mineral
   reserves and do not have demonstrated economic viability. Rounding of
   tons, as required by reporting guidelines, may result in apparent
   differences between tons and grade.
