Coeur Discovers High-Grade Mineralization at Kensington

CHICAGO, Oct. 6, 2014 (GLOBE NEWSWIRE) -- Coeur Mining, Inc. ("Coeur" or the "Company") (NYSE:CDE) announced high-grade drill results today from its Kensington gold mine in Alaska, including at the nearby Jualin zone.

Coeur expects to complete a new resource estimate for Kensington to incorporate these results by year-end 2014 and anticipates releasing a new mine plan in early 2015. The new mine plan is expected to reflect higher-grade production, lower unit costs, and higher cash flow over the life of the mine.

Highlights

Kensington:

  • Drilling has encountered high-grade gold in Kensington South (Zones 10 and 20) immediately beneath current production areas, 100 to 200 feet away from current mine development
  • Several holes have returned grades greater than 1.0 oz/ton gold
  • Grade and thickness of mineralization is improving at depth and to the southern portion of the ore body. The zones are open in all directions

Jualin:

  • Drilling activity in Jualin Veins 4 and 5 has encountered several multi-ounce gold intercepts
  • Underground development at Jualin is planned for 2015 and production from Vein 4 is expected to begin in 2017. Vein 4 is open in all directions

"The renewed focus of our drilling program at Kensington has discovered high-grade mineralization to enhance the economics of the mine, resulting in a considerable number of drill holes containing multi-ounce gold intercepts," said Hans Rasmussen, Coeur's Vice President, Exploration.

Frank Hanagarne, Coeur's Senior Vice President and Chief Operating Officer, said, "Operating consistency has improved at Kensington in the past two years, which has allowed us to increase our effort on exploration and long-term planning. The discovery at Jualin has the potential to significantly boost production grades, reduce unit costs, and increase free cash flow."

At December 31, 2013, Kensington estimated proven and probable reserves totaled 6.0 million tons at an average grade of 0.15 oz/ton containing 902,000 ounces of gold. Coeur expects to spend a total of $9.1 million for exploration at Kensington in 2014, including $1.7 million in capitalized drilling. This is $3.0 million higher than the initial budget, reflecting Coeur's success-based approach to funding exploration.

Jualin Vein 4 remains open at depth and to the north towards Kensington, reaching within 300 feet beneath the Jualin portal, which is near current mine infrastructure. Permitting is underway for underground development at Jualin to provide access to underground drill stations. Drilling in Vein 4 is expected to continue in 2015 and 2016 with initial production expected in 2017. Once underground development has advanced, drilling is expected to also focus on further delineation of Vein 5, which has been encountered only 500 feet beneath Vein 4.

Zones 10 and 20 of Kensington South, located just 100-200 feet away from current mine development, are expected to be further drilled and developed over the next year and bring additional high-grade production into the mine plan beginning in 2016.

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 NI 43-101-compliant Technical Report for Kensington dated January 1, 2013 and filed February 28, 2013 on 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 www.sec.gov.

Notes:

  1. Drill intercepts from 5,064 assays from full and half HQ and NQ core for infill holes, samples prepared at Kensington Mine, Juneau, AK, and at ALS-Chemex Labs, Reno, NV with final sample preparation to pulp and analyses at ALS-Chemex Labs, Reno, NV.
  2. Samples were analyzed by 30 gram fire assay with atomic absorption finish for Au <1 ppm or by 1000 gram Metallic Screen.
  3. Drill intercepts calculated at 0.05 oz/ton Au. Maximum of 5 feet of internal dilution (less than cutoff) permitted in compositing. "Including" calculated at 0.15 cut-off grade.
  4. All assays uncapped.
  5. External QA/QC checks performed at ALS-Chemex Labs, Reno, NV consisting of 299 duplicates and 313 standards and 313 blanks.
  6. External QA/QC checks were sent during June 2014.
