CHICAGO–(BUSINESS WIRE)–Coeur Mining, Inc. (“Coeur” or the “Company”) (NYSE: CDE) announced year-end contained proven and probable mineral reserves of approximately 302.2 million silver equivalent ounces, a decrease of 88.5 million silver equivalent ounces compared to year-end 2014, primarily due to the reclassification of silver reserves at La Preciosa to resources and from the production of 35.6 million silver equivalent ounces, comprised of 15.9 million silver ounces and 327,908 gold ounces, during 2015. In addition to these reserves, Coeur announced measured and indicated mineral resources totaling approximately 414.7 million silver equivalent ounces, and inferred mineral resources totaling 120.3 million silver equivalent ounces, a 42% increase and 5% decrease, respectively, compared to year-end 2014.

To reflect the current volatile metals price environment, Coeur has implemented short and long-term pricing assumptions in determining mineral reserves. Short-term reserve price assumptions for 2016 – 2017 are $15.50 per silver ounce and $1,150 per gold ounce, an 18% and 10% decrease, respectively, from year-end 2014 reserve price assumptions. Long-term reserve price assumptions for 2018 and beyond are $17.50 per silver ounce and $1,250 per gold ounce, an 8% and 2% decrease, respectively, compared to year-end 2014 reserve prices.

Highlights

All comparisons below refer to year-end 2015 compared with year-end 2014.

  • Proven and probable gold reserves increased 33% to 2.4 million ounces
  • Measured and indicated gold resources increased 28% to 1.7 million ounces
  • Inferred gold resources increased 7% to 1.2 million ounces
  • Largest source of reserve increase was from Wharf, acquired by Coeur in February 2015, which added 712,000 ounces of proven and probable gold reserves
  • Inferred resources at Kensington’s high-grade Jualin deposit total 179,000 gold ounces with an average grade of 0.619 ounces per ton, over three times the average reserve grade
  • Palmarejo silver equivalent reserves increased 44%, primarily as a result of the consolidation of the Independencia deposit, through the acquisition of Paramount Gold and Silver Corp. in April 2015
  • Proven and probable silver reserves decreased 44% to 155.9 million ounces
  • Measured and indicated silver resources increased 47% to 310.4 million ounces
  • Inferred silver resources decreased 18% to 50.4 million ounces
  • Largest source of silver reserve decrease was from La Preciosa, as 119 million ounces were reclassified from reserves to resources due to lower metals price assumptions

“Year-end 2015 reserves reflect the continuing theme of ‘quality over quantity’ of silver and gold ounces and align with our strategy to produce higher-grade, higher-margin ounces to maximize free cash flow across our operations,” said Mitchell J. Krebs, Coeur’s President and Chief Executive Officer. “We removed the lower-grade material that was not economical at these lower metals prices, primarily from La Preciosa, using silver and gold reserve prices over the next two years that are 18% and 10% lower, respectively, than year-end 2014. Companywide gold reserves increased by over 600,000 ounces at 33% higher grade compared with last year, primarily due to the addition of Independencia Este, Wharf, and higher grade material at Kensington.

“Our exploration efforts are driven by the discovery of high-grade deposits near our existing operations, and in 2016, will focus on expanding the resource in the Guadalupe-Independencia corridor, infill drilling of the high-grade East Rochester discovery, and expansion of the Jualin deposit at Kensington.”

Year-end 2014 mineral reserves and resources are effective December 31, 2014 except Endeavor, which is effective June 30, 2014. Year-end 2015 mineral reserves and resources are effective December 31, 2015 except Endeavor, which is effective June 30, 2015. Please refer to the tables in the Appendix for tons and average grades associated with references of contained ounces in each category in this news release. All reserves and resources reported herein comply with Canadian National Instrument 43-101 (“NI 43-101”).

Dana Willis, Coeur’s Director, Resource Geology 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, Canadian investors should refer to the relevant NI 43-101 Technical Report on file 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.

Silver equivalence assumes silver to gold ratio of 60:1.

Notes to the above mineral reserves and resources:

    1.  

Effective December 31, 2015 except Endeavor, effective July 1, 2015.

2. Assumed metal prices for estimated reserves were $17.50 per ounce silver and $1,250 per ounce gold, except San Bartolomé, Rosario and lower 76 underground deposits at Palmarejo at $15.50 per ounce of silver and $1,150 per ounce of gold, Endeavor at $2,400 per metric ton zinc, $2,200 per metric ton lead, and $17.00 per ounce of silver, and Wharf at $1,275 per ounce of gold. Proven and probable reserves (other than Endeavor) were also evaluated using $15.50 per ounce of silver and $1,150 per ounce of gold. It was determined that substantially all proven and probable reserves could be economically and legally extracted or produced at these lower price assumptions. Assumed metal prices for estimated 2014 proven and probable reserves were $19.00 per ounce silver and $1,275 per ounce gold except where otherwise noted.
3. 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.
4. Rounding of tons and ounces, as required by reporting guidelines, may result in apparent differences between tons, grade, and contained metal content.
5.
