Coeur Declares Commercial Production at its New Silvertip Operation; Updates Companywide Full-Year Production Guidance

Share:

Coeur Mining, Inc. ("Coeur" or the "Company") (NYSE:CDE) is pleased to
announce that it declared commercial production effective September 1,
2018 at its new high-grade Silvertip silver-zinc-lead mine ("Silvertip")
located in northern British Columbia.

"The commencement of commercial production at Silvertip is a significant
milestone," said Mitchell J. Krebs, Coeur's President and Chief
Executive Officer. "We completed the acquisition of Silvertip in October
2017 and commenced production in March after successfully commissioning
the mill. Since then, our team has been focused on optimizing plant
performance and on upgrading the mine's infrastructure. We continue to
be excited about the impact Silvertip is expected to have on our
production, margins and cash flow beginning next year.

"Optimization efforts at Silvertip will continue over the next several
quarters, with processing rates on-track to average 750 tonnes per day
("mtpd") by year-end and reach 1,000 mtpd in early 2019. We remain
on-track to publish an initial NI 43-101 Technical Report in the fourth
quarter and expect to receive approval of the permit amendment
application to operate at 1,000 mtpd around year-end."

During August, processing rates averaged approximately 450 mtpd, up from
approximately 350 mtpd during July and approximately 250 mtpd during
June. Processing rates regularly ranged between 500 to 650 mtpd during
August and exceeded 800 mtpd late in the month. During the same time,
plant availability improved to 80%, up from 75% in July and 65% in June.

Through July, the Company has invested a total of $51.3 million in
Silvertip ($5.8 million expensed and $45.5 million capitalized),
including $29.8 million of capitalized operating expenses, $8.0 million
of capitalized resource infill drilling and $2.1 million of expensed
resource expansion drilling. Near-term priorities for the Company
include the construction of improved camp facilities, acceleration of
underground development activity and the introduction of long hole stope
mining to selected areas. As of August 31, 2018, Silvertip had 250
employees.

Updated Companywide Production Guidance

In July, the Company increased its full-year production guidance from
36.0 – 39.4 million silver equivalent ounces ("AgEqOz")3 to
37.3 - 40.5 million AgEqOz3 due to strong first half
performance at its Palmarejo operation in Mexico.

Based on stronger than expected performance at its Rochester mine in
Nevada and on improved visibility of Silvertip's production now that
commercial production has been achieved, Coeur is revising its full-year
Companywide production guidance to 36.1 - 39.5 million AgEqOz3.
