  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

Business Wire

CHICAGO -- July 8, 2013

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 costs^1 of $13.86 per silver ounce, and is expected to average
approximately $93 million in operating cash flow^1 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.

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.

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.

Total sustaining capital expenditures   $ 84.2
                                          

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 doré.

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.
