NEWS RELEASE             

Coeur Reports Fourth Quarter and Full Year 2017 Production and Sales Results

and Provides 2018 Production Guidance

Chicago, Illinois - January 8, 2018 - Coeur Mining, Inc. (the "Company" or "Coeur") (NYSE: CDE) today announced record fourth quarter silver equivalent¹ production of 11.7 million ounces, consisting of 4.5 million ounces of silver and 119,114 ounces of gold. Silver equivalent¹ production increased 23% quarter-over-quarter and 17% year-over-year. Silver production increased 15% quarter-over-quarter and 17% year-over-year, while gold production increased 28% and 16%.

Full-year 2017 silver equivalent¹ production, also the highest in Company history, totaled 39.4 million ounces, which was 9% higher compared to 2016. Full-year silver production was 16.4 million ounces, 11% higher than in 2016 and at the high-end of the Company's guidance of 15.3 - 16.6 million ounces. Full-year gold production was 383,444 ounces, 7% higher than in 2016 and in-line with Company guidance of 367,000 - 392,000 ounces. Production growth was driven primarily by the Palmarejo mine, where 2017 silver equivalent¹ production increased 64% compared to 2016.

In 2018, Coeur expects to produce 36.6 - 40.0 million silver equivalent¹ ounces, consisting of 12.8 - 14.4 million ounces of silver, 355,000 - 375,000 ounces of gold, and 23.0 - 28.0 million pounds of both zinc and lead.

Metal sales for the fourth quarter of 4.6 million ounces of silver and 123,675 ounces of gold, or 12.0 million silver equivalent¹ ounces, were in-line with production. Full-year metal sales of 16.9 million ounces of silver and 410,715 ounces of gold, or 41.6 million silver equivalent¹ ounces, reflects a reduction in inventory carried over from 2016.

• Fourth quarter silver equivalent¹ production increased 26% quarter-over-quarter and 70% year-over-year to 4.6 million ounces, while full-year 2017 silver equivalent¹ production of 14.5 million ounces was above the high-end of the Company's guidance range and represented an increase of 64% over 2016

• Fourth quarter silver and gold grades rose approximately 25%, quarter-over-quarter, while full-year 2017 silver and gold grades increased 21% and 12%, respectively, compared to 2016 due to mining of higher-grade zones at Independencia. Grades are expected to decrease gradually during the first quarter of 2018 due to mine sequencing

• Higher recovery rates during the fourth quarter resulted from normalization of mill inventory levels

• Fourth quarter silver and gold sales were in-line with production, while full-year sales were higher than production due to a reduction in inventory carried over from the fourth quarter of 2016

• Gold sales during the quarter and year included 13,740 and 52,124 ounces, respectively, sold to Franco-Nevada at a price of $800 per ounce

• Full-year 2018 production is expected to be 6.5 - 7.1 million ounces of silver and 110,000 - 115,000 ounces of gold, or 13.1 - 14.0 million silver equivalent¹ ounces

• Fourth quarter silver equivalent¹ production increased 45% quarter-over-quarter to 2.5 million ounces, with silver production increasing 27% to 1.4 million ounces and gold production rising 73% to 18,995 ounces. Higher production was driven by concurrent leaching of the Stage III and Stage IV pads as well as the timing of recoveries from the newly-expanded Stage IV leach pad. Gold production also benefited from the placement of higher gold grade ore during the third quarter and early fourth quarter

• Full-year silver equivalent¹ production of 7.8 million ounces was relatively unchanged year-over-year due to the completion of construction and commissioning of the Stage IV leach pad

• Full-year 2018 production is expected to be 4.2 - 4.7 million ounces of silver and 45,000 - 50,000 ounces of gold, or 6.9 - 7.7 million silver equivalent¹ ounces

Gold ounces sold	125,982	35,634	29,173	29,031	32,144	121,688	28,864

• Fourth quarter gold production increased 27% quarter-over-quarter to 34,932 ounces, Kensington's highest quarterly production since the fourth quarter of 2013. This was primarily the result of mining the higher-grade Raven zone, which drove average grades 29% higher to 0.22 oz/ton

• Full-year production of 115,094 ounces was below the Company guidance range due to lower-than-expected grades throughout the first nine months of the year

• Full-year gold sales were higher than production due to reductions in inventory throughout the year, particularly in the first quarter

• During the fourth quarter, mining of development ore continued at Jualin, where production is expected to accelerate throughout 2018 as the Company dewaters the mine area to facilitate more efficient drilling, development, and mining activities

• Raven is expected to remain a supplemental source of higher-grade material throughout the year

• 2018 gold production is expected to total 115,000 - 120,000 ounces

Gold equivalent1	99,472	29,256	24,085	21,495	24,636	109,620	30,204

• At Wharf, gold production in the fourth quarter increased 6% quarter-over-quarter to 27,292 ounces, attributable primarily to strong sustained crusher production and gold grades

• For the full year, gold production decreased 13% to 95,372 ounces as a result of lower grades following completion of mining at the higher-grade Golden Reward deposit during the third quarter

• Tons placed for the full year reached 4.6 million, up from 4.3 million in 2016 and 3.6 million in 2015

• In 2018, the Company anticipates full-year production of 85,000 - 90,000 ounces of gold

Silver ounces sold (000's)	4,241	744	951	1,398	1,148	5,411	1,218

Note: San Bartolomé also produced and sold 358 and 111 ounces of gold, respectively, during the fourth quarter

• Lower fourth quarter and full-year silver production of 0.8 million and 4.3 million ounces, respectively, reflected persistent drought conditions in the Potosí region of Bolivia. In addition to restricting mill operations, water shortages have curtailed mining by third parties, from whom higher-grade ore is sourced

• On December 22, 2017, Coeur announced plans to divest the San Bartolomé mine through the sale of its 100%-owned Bolivian subsidiary to Argentum Investments, AB. The Company’s 2018 production guidance of 0.6 million silver ounces reflects the anticipated closing of this transaction in the first quarter of 2018

• Coeur will present San Bartolomé as discontinued operations when it reports fourth quarter and full-year 2017 financial results on February 7, 2018. The mine will be excluded from consolidated operating metrics and financial results, which reflect continuing operations, unless otherwise noted
