CHICAGO, July 30, 2014 (GLOBE NEWSWIRE) — Coeur Mining, Inc. ("Coeur" or the "Company") (NYSE:CDE) announced results from a feasibility study on the La Preciosa silver-gold project located in Durango state, Mexico and announced the Company's decision to defer construction activities at this time.
Mitchell J. Krebs, Coeur's President and Chief Executive Officer, said, "Our team was able to improve the economics of La Preciosa by an estimated $180 million since completing a Preliminary Economic Assessment ("PEA") in June of last year. However, a 29% decline in silver prices since announcing the acquisition of Orko Silver in February 2013 and higher taxes on precious metals mines in Mexico have led the Company to conclude that now is not the optimal time to proceed with construction of La Preciosa.
"We consider La Preciosa to be one of the best silver projects in North America and I am confident it will become a cornerstone mine for Coeur at some point in the future. The proposed mine would be Coeur's largest source of silver production and would lower the Company's overall cost structure. Our decision to not proceed at this time was based on our disciplined capital deployment philosophy and our commitment to retaining a flexible, liquid balance sheet. The feasibility study demonstrates a very attractive project at higher silver and gold prices. Deferring construction enables us to maintain the project's leverage to better macro conditions and provides time to pursue limited drilling and metallurgical work to further improve the expected project economics."
Highlights of the Feasibility Study:
- 10% internal rate of return ("IRR") based on silver and gold prices of $22 and $1,350 per ounce, respectively
- Declared initial proven and probable mineral reserves of 126 million silver ounces and 209 thousand gold ounces increases Companywide silver and gold reserves by 50% and 10%, respectively
- Once in production, La Preciosa would be the world's sixth largest primary silver mine1 with average annual silver production of over ten million ounces
- 12% decrease in projected initial capital expenditures compared to the PEA to $307 million
- 10% decline in expected costs applicable to sales per silver equivalent ounce2 versus the PEA to $14.37
- 5% increase in overall silver grade compared to the PEA
- Feasibility work completed on time and under budget
1. Based on 2013 production published by The Silver Institute.
2. Non-GAAP measure. Silver equivalence assumes 60:1 ratio.

Coeur plans to continue limited activity at La Preciosa, including a $1.5 million exploration program with an emphasis on potential high-grade resource conversion, metallurgical optimization testwork, and testwork on a potential heap leach scenario for lower-grade material. This additional optimization work is expected to be completed by in the first half of 2015. The expected annual holding cost of deferring mine construction is less than $2 million.
On July 2, 2014, Coeur acquired a pre-existing 3% NSR on La Preciosa for $12.0 million.
Detailed results of the feasibility study will be included in a Canadian National Instrument 43-101 compliant Technical Report that will be filed on SEDAR within 45 days.

W. David Tyler, Coeur's Vice President, Technical Services and a qualified person under Canadian National Instrument 43-101, supervised the preparation of 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, please refer to the relevant NI 43-101-compliant Technical Report on file at www.sedar.com and the new Technical Report for the La Preciosa feasibility study to be filed within 45 days onwww.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 www.sec.gov.
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 costs applicable to sales per silver equivalent ounce. We believe that this adjusted measure provides meaningful information to assist management, investors and analysts in understanding our financial results and assessing our prospects for future performance. We believe this adjusted financial measure is an important indicator of our recurring operations because it excludes items that may not be indicative of, or are unrelated to our core operating results, and provides a better baseline for analyzing trends in our underlying businesses. We believe costs applicable to sales per silver equivalent ounce is an important measure in assessing the Company's overall financial performance.
All tons are reported in U.S. standard short ton units. Grades reported are troy ounces per short ton.

Notes to the above mineral reserves and resources:
- Effective December 31, 2013 except Endeavor, effective June 30, 2013, and La Preciosa effective July 29, 2014.
- Metal prices used for mineral reserves were $25.00 per ounce of silver and $1,450 per ounce of gold, except Endeavor, at $2,300 per metric ton of lead, $2,300 per metric ton of zinc, and $34.00 per ounce of silver, and La Preciosa at $22.00 per ounce of silver and $1,350 per ounce of gold. Metal prices used for mineral resources were $29.00 per ounce of silver and $1,600 per ounce of gold, except for Endeavor, at $2,300 per metric ton of lead, $2,300 per metric ton of zinc and $34.00 per ounce of silver, and La Preciosa at $25.00 per ounce of silver and $1,400 per ounce of gold.
- Palmarejo mineral resources (measured, indicated, and inferred) reported above represent the sum of Palmarejo, Guadalupe, and La Patria resources.
- Kensington proven and probable reserves adjusted April 2014 to reduce the grade of internal dilution to zero.
- 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.
- Rounding of tons and ounces, as required by reporting guidelines, may result in apparent differences between tons, grade, and contained metal content.
- 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 new Technical Report for the La Preciosa feasibility study to be filed within 45 days on www.sedar.com.
