NEWS RELEASE: Coeur Announces Acquisition of the Silvertip Mine in British Columbia

Chicago, Illinois – September 11, 2017 – Coeur Mining, Inc. (“Coeur” or the “Company”) (NYSE: CDE) is pleased to announce that it has entered into a definitive agreement (the “Arrangement Agreement”) to acquire privately-owned JDS Silver Holdings, Ltd. and its wholly-owned subsidiary, JDS Silver Inc. (“JDS Silver”), which owns the high-grade silver-zinc-lead Silvertip mine (“Silvertip”) located in northern British Columbia, Canada, adding a sixth producing mine to Coeur’s North American-focused platform.

Under the Arrangement Agreement, the Company will pay initial consideration of US$200 million, consisting of US$146.5 million of cash, US$38.5 million of Coeur shares (approximately 4.3 million new shares), and will assume US$15 million in existing debt. Additional potential payments of up to US$50 million are contingent upon achieving specific future permitting and exploration milestones at Silvertip.

Overview of Silvertip

The Silvertip mine is one of the industry’s newest and highest-grade silver-zinc-lead mines with a silverequivalent1 indicated resource grade of 1,166 grams per tonne (g/t), comprised of 352 g/t silver, 9.4% zinc,and 6.7% lead, and a silver-equivalent1 inferred resource grade of 1,155 g/t, comprised of 343 g/t silver, 9.8% zinc, and 6.2% lead. Located just below the Yukon border, the operation sits within a highly prospective 93,000-acre (37,650 hectares) land package. Silvertip commenced production during the fourth quarter of 2016.

Upon expected completion of the transaction in late October, Coeur intends to invest US$25 – US$35 million in surface infrastructure, accelerated underground development and drilling and mill optimization over a six-month period and recommence commercial production by the end of the first quarter of 2018. Once an anticipated daily average mining rate of 1,000 tonnes per day is achieved, Coeur expects Silvertip to produce an average of approximately ten million silver equivalent1 ounces annually consisting of approximately three million ounces of silver, 45-50 million pounds of zinc, and 40-45 million pounds of lead over an estimated 7.5-year initial mine life.

Key Transaction Highlights

 Significant, high-quality near-term production growth – Expected average annual silver
equivalent1 production from Silvertip of approximately ten million ounces represents a significant potential increase to Coeur’s overall production profile compared to Coeur’s 2017 production guidance range of 38 – 41 million silver equivalent1 ounces.
