Coeur Releases New High-Grade Mine Plan at Kensington Gold Mine

Reflects Impact of New High-Grade Mineralization From Ongoing Exploration Success

Full-Year Production Expected to Increase 34% to 149,000 Ounces at 23% Lower Operating Costs of $732 Per Ounce in 2018 Driven by 25% Higher Grade

CHICAGO, April 14, 2015 (GLOBE NEWSWIRE) -- Coeur Mining, Inc. ("Coeur" or the "Company") (NYSE:CDE) announced an updated and re-scoped mine plan and a preliminary economic assessment for its Kensington gold mine located in Southeast Alaska. The new mine plan reflects the recent discovery of the high-grade Jualin zone and indicates higher overall production and significantly higher cash flows due to the contribution of higher-grade material from three nearby zones.

The Jualin zone, located approximately 8,250 feet from current mining activities, continues to expand based on ongoing drilling and contains an average gold grade over three times the average reserve grade of 0.185 oz/ton. Annual gold production between 2015 and 2020 at Kensington is expected to average approximately 128,000 ounces and costs applicable to sales ("CAS") are expected to average $820 per gold ounce. Production in 2014 was 117,823 ounces at a CAS of $951 per gold ounce.

"Our recent success identifying high-grade mineralization near existing Kensington infrastructure has added higher-margin production to our mine plan and significantly improved the expected economics of the mine," said Mitchell J. Krebs, Coeur's President and Chief Executive Officer. "Kensington's new mine plan is expected to be a key component of the Company's overall strategic repositioning that is expected to increase overall production levels by approximately 30%, reduce overall unit costs by approximately 25%, and boost the Company's free cash flow to $190-$200 million in 2017."

"Importantly, the required capital to place Jualin into production is estimated to be $30 million and has an expected rate of return of around 70%. Incorporating a portion of expected production from Kensington's high-grade zones and the Jualin ore body has quadrupled our expected net cash flow at Kensington through 2022 and we believe considerable upside exists based on recent drill results. Through continued drilling, our goal is to expand these sources of high grade resources and extend the 2018 profile."

The new mine plan for Kensington is a re-scoping of the existing mine plan contemplated in the December 31, 2014 Technical Report due to the high-grade discovery made in the Jualin vein system. The mine plan includes development of a decline to Jualin and new underground mine development, and reflects the inclusion of a portion of the estimated inferred mineral resources, which the Company expects to upgrade to measured and indicated resources and convert to reserves through a $9.1 million drilling program over the next two years through more efficient drilling from underground. This program includes 44,000 feet of drilling from the 3,000 feet of planned development at Jualin.

Expected capital expenditures include approximately $3.5 million per year through 2018 for capitalized drilling, primarily to upgrade the inferred mineral resources at Kensington and Jualin. Spending for underground mine development is expected to average $16 million per year through 2018 when production from the inferred material is expected to be fully ramped up. Development of the decline to Jualin is planned to begin in July 2015 with initial production expected in mid-2017 at a mining rate of approximately 250 tons per day, which is expected to increase to 500 tons per day in early 2018 and represent approximately 27% of the average daily mill feed.

Results from recent drilling activity detailed below are not reflected in the reserves and resources used in the re-scoped mine plan. This includes new holes in Jualin Vein 4 from the surface which cut mineralization approximately 1,000 feet away from the existing inferred resource included in the mine plan, demonstrating the possibility to expand Vein 4. High-grade drill results from other zones at Kensington as well as planned drilling in Veins 1, 2, 3, and 5 at Jualin suggest considerable upside exists to increase the size of the overall Jualin zone and bring additional high-margin production into the mine plan as drilling continues.

A slide deck to accompany this release is posted at www.coeur.com.

The preliminary economic assessment for the re-scoped mine plan is preliminary in nature and includes inferred mineral resources, and does not have as high a level of certainty as a plan that was based solely on proven and probable reserves. 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 results from the preliminary economic assessment will be realized.
