Coeur's La Preciosa Project PEA Indicates 17-Year Initial Mine Life; Average Annual Silver Production of 9.1 Million Ounces over the First 14 Years

Coeur Mining, Inc. (the 'Company? or 'Coeur?)(NYSE: CDE, TSX:
CDM) announced results from a Preliminary Economic Assessment (PEA) for
its wholly-owned La Preciosa silver-gold project located in Durango
state, Mexico. The PEA indicates an initial estimated mine life of 17
years recovering an estimated 134.5 million ounces of silver and
generating a 17% after-tax internal rate of return (IRR) using price
assumptions of $25 per silver ounce and $1,500 per gold ounce.

Over the first 14 years of production, La Preciosa is expected to
produce an average 9.1 million ounces of silver per year at anticipated
average cash operating costs¹ of $13.86 per silver ounce, and
is expected to average approximately $93 million in operating cash flow¹
per year. At forecast production rates, La Preciosa would be one of the
top 10 primary silver mines in the world. The references herein are in
U.S. dollars and U.S. customary units.

Table 1: PEA (Base Case) Highlights and Assumptions

Mitchell J. Krebs, Coeur's President and Chief Executive Officer, said,
'The results of this initial PEA demonstrate the viability of the La
Preciosa open pit project at higher silver and gold prices and provide a
solid foundation from which we believe we will enhance the project's
economics over time. Subject to Board authorization, the Company intends
to proceed with a feasibility study, which is expected to be completed
in mid-2014. Upon completion of the feasibility study, the Company and
its Board will evaluate the economics of the project, assess the silver
market and determine whether to proceed with construction.?

Mr. Krebs commented, 'Over the next 12 months, we will pursue an
exploration and infill drilling program focused on expanding the
deposit, upgrading inferred mineral resources and drilling on several of
the smaller veins and mineralized intercepts which fall within the
designed pits to increase confidence levels, evaluate mineability and
determine whether they can be incorporated into future mine plans.

'La Preciosa is located in mining-friendly Mexico, just 45 minutes from
the city of Durango, with many local mines and a readily available
workforce. It has easy access to power and transportation and we believe
we now have the water supply necessary to support future mining
activities.?

La Preciosa PEA Highlights and Assumptions

• 
  Measured and indicated resources of 57.2 million tons containing 146.2
  million silver ounces and 277,700 gold ounces, and inferred resources
  of 19.5 million tons containing 37.7 million silver ounces and 60,300
  gold ounces at June 26, 2013. (Please refer to the Appendix Table for
  related grades for the updated mineral resource estimate.)
  
• 
  Expected average recovery rates of 86% for silver and 82% for gold at
  a throughput rate of 11,023 tons per day (10,000 tonnes per day) for
  average annual production of 9.1 million silver ounces and 15,100 gold
  ounces over the initial 14 years of mine life.
  
• 
  Coeur's open pit mine plan estimates production of 59.1 million tons
  at average grades of 2.40 ounces of silver per ton and 0.004 ounce of
  gold per ton. The project envisions surface mine operation for the
  first 14 years and continued operation of the processing plant from
  stockpiled lower-grade ore for the final three years.
  
• 
  Capital expenditures are estimated to be $347.9 million for commercial
  start-up and an additional $84.2 million of sustaining capital over
  the initial estimated 17-year mine life.
  
• 
  After-tax IRR of 17% and a NPV of $314 million at a base case using a
  5% discount rate, $25 per ounce silver price and $1,500 per ounce gold
  price, represents a payback period of 5.3 years.
  
• 
  Located in a mining-friendly jurisdiction with infrastructure in
  place, including anticipated access to power and transportation and
  available water supply.
  

The La Preciosa PEA demonstrates leverage to a rising silver price as
shown in the Economic Sensitivity Analysis below.

Payback Period

(Base case at $25 silver price is shown in bold below.)

Capital Expenditures

Estimated capital expenditures are shown in the table below. Mobile
mining equipment valued at $84 million is assumed to be leased and is
not included in the estimated capital expenditures. The cost of leasing
is $2.88 per ton ore processed and is included in operating costs.
Sustaining capital expenditures are estimated to total $84.2 million
over the initial 17-year mine life. The Company used a high level of
design and engineering rigor for this PEA-level study with more than 50%
of the capital equipment estimates supported by current price quotations.

Table 3: Capital Expenditures

Mining and Processing

The PEA envisions using hydraulic shovels, loaders and a fleet of
195-ton haul trucks for the open pit operations. The processing plant
incorporates an 11,000 ton per day mill with agitated leach, counter
current decantation clarification and a Merrill-Crowe plant to produce
silver-gold dor?.

Table 4: Cost Parameters

Opportunities for Optimization

Recommendations in the PEA for cost saving opportunities range from
optimizing the mine design and conducting infill and exploration
drilling to expanding reserves and optimizing metallurgical recoveries.
Coeur also expects to further evaluate in-pit waste disposal sites,
grinding, power consumption and the tailings storage method.

Feasibility Study Phase

The feasibility study phase will focus primarily on the open pit mine
optimization and metallurgical testing to maximize plant operating
efficiency and recoveries. Geomechanical studies will evaluate rock
strength and fracture characteristics to provide information for slope
design. The evaluation will also include tradeoff analyses comparing dry
stack versus conventional tailing storage, tailing locations, and
alternate cyanide destruction methods. The feasibility study will also
investigate the potential to supplement or extend mine production
through the inclusion of underground mining of resources that lie beyond
the boundary of the currently designed surface pit.

In parallel with the feasibility process, Coeur will complete baseline
environmental work and prepare an Environmental Impact Statement as a
part of an application for construction and operating permits.

Coeur anticipates total 2013 expenditures of $12 million, including $6
million for the PEA and $5 million for exploration and feasibility work,
and an additional $18 million of expenditures in 2014, including $5
million for exploration. All such costs will be expensed.

Exploration Upside

La Preciosa is situated within a contiguous block of concessions
totaling more than 125 square miles (32,400 hectares). The La Preciosa
deposit and the majority of prior exploration work are contained within
a smaller core of concessions covering approximately 4.2 square miles
(1,100 hectares), or 3% of the total land package. Coeur believes the
surrounding, larger land package contains similar host rocks and
structural features to those in the core concessions but these have not
yet been explored in a systematic manner.

The Company's exploration priorities will be to (i) upgrade key inferred
mineral resources included in the current PEA mineral resource results
to at least indicated status, (ii) commence exploration near the current
mineral resources for extensions and new mineral occurrences and, (iii)
conduct a full district compilation of all historic data to assist with
regional exploration.

Project Timetable

A construction decision will be made following completion of the
feasibility study in the second half of 2014. Assuming a positive
decision, construction is expected to take two years, with potential
initial production beginning in the second half of 2016.

The PEA was completed by M3 Engineering & Technology Corporation (M3) of
Tucson, Arizona, with the support of Independent Mining Consultants,
Inc. (IMC) and Resource Evaluation, Inc. (REI) of Tucson, Arizona. Coeur
selected M3 to conduct the PEA due to their extensive experience in
Mexico, having designed and constructed over 16 mining projects in the
country, including Goldcorp's Peñasquito mine.

The PEA is preliminary in nature and it includes inferred mineral
resources that are considered too speculative geologically to have the
economic considerations applied to them that would enable them to be
characterized as mineral reserves and there is no certainty that the
results reflected in the PEA will be realized. Mineral resources that
are not mineral reserves do not have demonstrated economic viability.
Mineral resource estimates do not account for mineability, selectivity,
mining loss and dilution. There is no certainty that the inferred
mineral resources will be converted to the measured and indicated
categories or that the measured and indicated mineral resources will be
converted to the proven and probable mineral reserve categories.

Non-U.S. GAAP Measures

We supplement the reporting of our financial information determined
under United States generally accepted accounting principles (U.S. GAAP)
with certain non-U.S. GAAP financial measures, including cash operating
costs and operating cash flow. We believe that these adjusted measures
provide meaningful information to assist management, investors and
analysts in understanding our financial results and assessing our
prospects for future performance. We believe these adjusted financial
measures are important indicators of our recurring operations because
they exclude items that may not be indicative of, or are unrelated to
our core operating results, and provide a better baseline for analyzing
trends in our underlying businesses. We believe cash operating costs and
operating cash flow are important measures in assessing the Company's
overall financial performance.
