Chicago, Illinois – October 5, 2017 – Coeur Mining, Inc. (the "Company" or "Coeur") (NYSE: CDE) today announced third quarter production of 9.5 million silver equivalent¹ ounces, comprised of 4.0 million silver ounces and 93,293 gold ounces. Third quarter silver equivalent¹ production increased 7% quarter-over-quarter and 10% year-over-year. Higher quarter-over-quarter silver equivalent¹ production was driven by a 13% increase in gold production while higher year-over-year silver equivalent¹ production was due to a 10% increase in gold production and an 11% increase in silver production. Metal sales of 3.8 million ounces of silver and 89,972 ounces of gold, or 9.2 million silver equivalent¹ ounces, were in-line with third quarter production.

Quarterly Production Results

Third quarter production and sales highlights for each of Coeur's operations are provided below. 

• Silver equivalent production increased 25% quarter-over-quarter and 89% year-over-year to 3.6 million ounces
• Average mining rates during the quarter were up 22%, achieving the year-end target of 4,500 tons per day one quarter early. This was driven by higher-than-budgeted mining rates at Independencia, which increased approximately 70% quarter-over-quarter to over 1,800 tons per day
• The average silver grade increased 11% as a result of mining higher grade stopes in the Independencia deposit that became accessible following the installation of additional ground support during the prior quarter
• Higher mining rates and silver grades during the quarter resulted in increased mill inventory at quarterend and contributed to lower recovery rates quarter-over-quarter
• Silver and gold sales of 1.8 million ounces and 26,554 ounces, respectively, were in-line with production. Gold sales during the quarter included 9,400 ounces sold to Franco-Nevada at a price of $800 per ounce
• Palmarejo's full-year production guidance of 6.5 – 7.0 million silver ounces and 110,000 – 120,000 gold ounces remains unchanged

• Silver equivalent production of 1.7 million ounces was relatively unchanged quarter-over-quarter
• Following three years of permitting and ten months of construction, the Stage IV leach pad expansion was successfully commissioned on schedule early in the third quarter
• Tons placed decreased 5% quarter-over-quarter, primarily due to crusher downtime related to the integration of the crusher into the expanded Stage IV system, planned annual maintenance and a brief power disruption due to a nearby wildfire
• Leaching of the expanded Stage IV pad began in the quarter and is expected to drive strong production through the end of the year. Fourth quarter gold production is also expected to benefit from the placement of higher gold grade ore on the expanded Stage IV pad during the third quarter
• The Company is maintaining Rochester's full-year production guidance of 4.2 – 4.7 million silver ounces and 47,000 – 52,000 gold ounces

• Gold production increased 4% quarter-over-quarter and year-over-year to 27,541 ounces
• Development of Jualin achieved an important milestone as initial development ore was mined during the quarter; mining from Jualin is expected to ramp up as planned over the next twelve months
• Higher anticipated grades are expected to drive strong production in the fourth quarter. As a result, the Company is maintaining Kensington's full-year guidance of 120,000 – 125,000 gold ounces

• Gold production at Wharf increased 21% quarter-over-quarter to 25,849 ounces. Increases in gold grade and production were largely driven by the higher-grade Golden Reward deposit, which was mined for an abbreviated season relative to prior years and is now complete
• Tons placed increased 16% during the quarter with Wharf on track to place 4.5 million tons for the full year, up from 4.3 million tons in 2016
• The Company is maintaining Wharf's full-year production guidance of 90,000 – 95,000 gold ounces

• Third quarter production decreased 26% to 1.0 million silver ounces primarily due to worsening drought conditions in the Potosí region of Bolivia, which hindered mill operations
• As a result, the Company is lowering San Bartolomé's full-year production guidance to 4.5 – 4.75 million ounces of silver from 5.0 – 5.4 million ounces

2017 Production Guidance

Coeur's 2017 production guidance has been revised to reflect lower expected silver production at the San Bartolomé mine due to persistent drought conditions.
