During the quarter, the Company also announced it had commenced production at its high-grade Silvertip mine in British Columbia, Canada slightly ahead of schedule. Mill throughput continues to ramp-up according to plan with commercial production expected to be achieved by mid-year.

Coeur's full-year production guidance of 36.0 - 39.4 million silver equivalent¹ ounces remains unchanged.

Operations

First quarter 2018 production and sales highlights for each of Coeur's operations are provided below.

• Year-over-year quarterly silver production increased 31%, while quarterly gold production declined 3%. First quarter silver and gold production decreased 14% and 20% quarter-over-quarter, respectively, to 2.0 million and 29,896 ounces
• Silver and gold grades were 40% and 11% higher, respectively, year-over-year and flat quarter-over-quarter. Palmarejo's production benefited from mining of higher grade material over the past two quarters in a faulted zone within Independencia, which the Company had conservatively modeled. This was offset by temporarily lower mining rates as additional ground support was installed along the fault. Grades are expected to gradually decrease in subsequent quarters, while mining rates are expected to return to 4,500 tons per day
• At the end of the first quarter, Palmarejo began commissioning an on-site absorption, desorption, and recovery ("ADR") plant, which resulted in a temporary increase in in-process inventory and lower recovery rates, which are expected to normalize during the second quarter
• During the quarter, 9,906 ounces, or approximately 32%, of Palmarejo's gold sales were to Franco-Nevada at a price of $800 per ounce. For the full year, the Company anticipates a similar percentage of Palmarejo's gold sales to be to Franco-Nevada
• Full-year 2018 production guidance is unchanged at 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

• Total tons placed increased 4% quarter-over-quarter and 24% year-over-year
• Production returned to normalized levels during the first quarter, with silver equivalent¹ production totaling 1.8 million ounces, which was 6% higher year-over-year. Compared to the prior quarter, production declined 26%. Fourth quarter 2017 production reflected accelerated recoveries from the newly-expanded Stage IV leach pad and from the placement of higher-grade gold ore during the second half of 2017
• The Company is maintaining full-year 2018 production guidance of 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

• As anticipated, first quarter gold production declined 34% quarter-over-quarter and 14% year-over-year to 17,936 ounces primarily due to lower grades
• While production levels are anticipated to be higher throughout the remainder of the year, 2018 is expected to be a lower grade year as previously disclosed. Higher stripping rates during 2018 are expected to result in access to higher grade material in subsequent years
• Full-year production guidance of 85,000 - 90,000 ounces of gold remains unchanged

• First quarter gold production declined 25% quarter-over-quarter to 26,064 ounces due to lower planned grades related to mine sequencing as well as maintenance-related mill downtime. Production was flat compared to last year's first quarter
• Development mining continued at Jualin during the quarter, where production is expected to increase in the second half of the year following completion of dewatering efforts. During the second quarter, production at Kensington is expected to remain consistent with first quarter production levels
• 2018 gold production guidance remains unchanged at 115,000 - 120,000 ounces
