CHICAGO--(BUSINESS WIRE)--Coeur Mining, Inc. (“Coeur” or the “Company”) (NYSE: CDE) today announced initial reserve and updated resource estimates, based on drilling results received through October, for its Silvertip silver-zinc-lead mine (“Silvertip”) located in northern British Columbia. The Company also provided a reserve-based mine plan and economic analysis underpinned by these estimates. A technical report in support of the information described herein and prepared in accordance with National Instrument 43-101 (“NI 43-101”) will be filed on SEDAR at www.sedar.com within 45 days of this release.
“We are pleased with the successful conversion of a large portion of the resource to an initial reserve and related mine plan at Silvertip,” said Mitchell J. Krebs, Coeur’s President and Chief Executive Officer. “We look forward to continuing our exploration efforts to expand the size of this prospective, high-grade deposit and further extend the mine life. In the near-term, we remain focused on optimizing the processing plant as well as achieving a sustainable level of mining and processing activities, which is reflected in this initial mine plan. We have made substantial progress over the past fourteen months since acquiring Silvertip and will carry that momentum into 2019. Silvertip has enhanced our geographic and political risk profile and is expected to be a long-term source of high-margin cash flow. We remain excited about its potential and its evolution into one of the Company’s cornerstone assets.”

Background and Recent Developments
The Company acquired Silvertip in October 2017 for initial consideration of $200 million. Additional consideration up to $50 million is payable contingent upon achieving specific future permitting and exploration milestones at Silvertip.
The first milestone payment of $25 million is contingent upon the receipt of a permit expansion allowing for a sustained mining and milling rate of 1,000 mtpd (1,100 tpd) on a year-round basis. The Company has been working closely with regulators and remains on track to receive approval of the permit amendment application in early 2019. The Company will make the $25 million payment (75% cash / 25% stock) within fifteen business days of receiving approval. The second milestone payment of up to $25 million is contingent upon the amount of resource tonnes added as of December 31, 2019, with $5 million payable for a total resource of at least 2.5 million tonnes and $5 million for each additional increment of 0.3 million tonnes up to 3.7 million tonnes.
Coeur commenced mining and processing activities at Silvertip in March 2018 and declared commercial production on September 1, 2018. The Company completed its initial drilling program in July 2018 and commenced a second phase drilling program focused on resource conversion and expansion drilling. Year-to-date6, the Company has invested approximately $11 million in exploration at Silvertip, including $8 million on capitalized infill drilling and $3 million on expensed resource growth and greenfields drilling.
The Company remains focused on improving process plant performance, underground rehabilitation and development as well as completing several key surface infrastructure projects, including the 220-person camp facility. Construction of the camp facility is on schedule and budget, with completion expected at the end of January 2019. Coeur also recently completed the scheduled upgrades to Silvertip’s water treatment plant and is currently treating water at its permitted capacity. The Company continues to target mill projects that address safety, production and efficiency improvements.

Christopher Pascoe, Coeur's Director, Technical Services and a qualified person under NI 43‐101, reviewed and approved the scientific and technical information concerning Coeur's mineral projects in this news release. Mineral resources are in addition to mineral reserves and do not have demonstrated economic viability. Inferred mineral resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be considered for estimation of mineral reserves, and there is no certainty that the inferred mineral resources will be realized. A description of the key assumptions, parameters and methods used to estimate mineral reserves and resources, as well as data verification procedures and a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, socio‐political, marketing or other relevant factors, will be included in the technical report for Silvertip that will be filed on SEDAR at www.sedar.com within 45 days of this release and is consistent with technical reports for each of Coeur's properties as filed on SEDAR at www.sedar.com.
