Quarterly Production Results. Note: On February 28, 2018, Coeur divested the San Bartolomé mine through the sale of its 100%-owned Bolivian subsidiary. As a result, San Bartolomé is excluded from consolidated operating statistics for all periods presented unless otherwise noted. (Graphic: Business Wire)

The Company has raised its full-year production guidance to 37.3 - 40.5 million silver equivalent¹ ounces, increasing silver production guidance to 13.2 - 14.6 million ounces from 12.2 - 13.8 million ounces and gold production guidance to 360,000 - 380,000 ounces from 355,000 - 375,000 ounces due to higher grades at its Palmarejo operation.

Operations

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

• Second quarter silver equivalent¹ production of 4.1 million ounces was 7% higher compared to the first quarter, with silver production of 2.1 million ounces relatively flat and gold production of 33,702 ounces 13% higher. Compared to the same period the prior year, silver and gold production increased 42% and 39%, respectively
• Production continued to benefit from higher-than-projected grades at Independencia, offsetting lower mining rates caused by the ongoing installation of ground support. During the second half, these underground improvements are expected to facilitate a return to mining rates above 4,500 tons per day ("tpd") while expected lower grade stopes are mined
• The new on-site absorption, desorption, and recovery ("ADR") plant began processing run-of-mine and carbon inventory, which was stockpiled in the first quarter. Average recovery rates normalized during the second quarter as this inventory was processed
• The ADR plant is expected to reach operational steady-state by year-end and has begun generating savings in refinery and freight costs as well as reducing the amount of carbon purchases
• Development towards the La Nación deposit, located between the Independencia and Guadalupe underground mines, has commenced and the Company anticipates production beginning in early 2019. Preliminary plans contemplate La Nación contributing approximately 400 tpd of mill feed once ramped up
• Approximately 32% of Palmarejo's gold sales in both the second quarter and first half of 2018 (or 9,834 and 19,739 ounces, respectively) were to Franco-Nevada at a price of $800 per ounce. The Company anticipates a similar percentage of Palmarejo's gold sales to be to Franco-Nevada in the second half of the year
• The Company is increasing Palmarejo's full-year 2018 production guidance to 7.5 - 7.9 million ounces of silver and 115,000 - 120,000 ounces of gold, or 14.4 - 15.1 million silver equivalent¹ ounces, from 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 decreased 6% quarter-over-quarter and 9% year-over-year primarily due to fewer run-of-mine tons placed
• Gold production increased 7% compared to the prior quarter and 14% year-over-year and was driven by the placement of higher gold grade ore close to the liner on the newly-expanded Stage IV leach pad. Quarterly silver production of 1.1 million ounces was in line with the prior quarter and the second quarter of 2017
• Higher production during the second half is expected to be driven by the ongoing ramp up of the Stage IV leach pad and continued placement of higher grade gold ore
• 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

• Quarterly tons placed were comparable to the first quarter and were impacted by scheduled maintenance downtime and weather. As anticipated, gold production increased 25% quarter-over-quarter and 5% year-over-year to 22,507 ounces due to timing of leach pad recoveries
• During the second half of the year, sustained higher mining and crushing rates are expected to drive increased production levels while average grade is expected to remain relatively constant. Planned higher stripping rates for the remainder of 2018 are expected to provide access to higher grade material in subsequent years
• The Company is maintaining full-year 2018 production guidance of 85,000 - 90,000 ounces of gold

• As anticipated, second quarter gold production of 25,570 ounces was consistent quarter-over-quarter due to lower planned grades related to mine sequencing
• Dewatering efforts at Jualin remain on-schedule and are expected to be completed during the third quarter, facilitating ramp up of production through year-end. As a result, production for the remainder of 2018 is expected to be weighted towards the fourth quarter
• The Company is maintaining full-year 2018 production guidance of 115,000 - 120,000 ounces of gold

Silvertip, British Columbia

• After successfully commissioning the mill in March, throughput rates steadily climbed throughout the second quarter. During the second half of June, throughput averaged slightly above 300 metric tonnes per day and in the final days of the month achieved 500 metric tonnes per day
• Mining activities remain focused on underground rehabilitation and development while surface activities are focused on the planning, construction and commissioning of various process optimization projects and infrastructure upgrades
• Exploration at Silvertip targeting resource conversion is progressing ahead of schedule with over 40,000 meters (133,000 feet) drilled since the program began in late 2017. Results have been positive, and the Company anticipates publishing an exploration update in late July in addition to a technical report later this year
• The Company submitted a permit amendment application to operate at 1,000 metric tonnes per day earlier in the quarter and anticipates receiving approval around year-end
• The Company is maintaining full-year 2018 production guidance of 1.5 - 2.0 million ounces of silver and 23.0 - 28.0 million pounds of both zinc and lead
