ABSTRACT:Chicago, Illinois – February 26, 2018 – Coeur Mining, Inc. (“Coeur” or the “Company”) (NYSE: CDE) today released a re-scoped mine plan and preliminary economic assessment (“PEA”) for its Rochester silver-gold mine in Nevada. The PEA, which will be included in a NI 43-101 Technical Report expected to be filed on March 5, 2018, incorporates the positive economic impact expected from the potential addition of a high pressure grinding roll (“HPGR”) to Rochester’s crushing circuit in early 2019 at an estimated cost of approximately $20 million. In addition, the PEA reflects lower projected capital expenditures related to the planned construction of a larger scale, more efficient crusher expected to include a second HPGR unit, beginning in 2020. The introduction of HPGR technology has the potential to increase Rochester’s silver recoveries from 61% over 20 years to 70% in just over two years, significantly improving the mine’s economics. The re-scoped mine plan incorporates inferred material in the open pit, thereby reducing Rochester’s strip ratio by more than half from 0.8:1 to less than 0.4:1. Coeur plans to finalize engineering of the potential HPGR addition in the coming months and complete infill drilling over the next three years with the goal of upgrading this inferred material to reserves.
