Major Expansion At The Rochester Operation In Nevada

CHICAGO - Coeur Mining, Inc. President and CEO, Mitchell J. Krebs, said, “The first quarter results reflect strong overall production and cost management, which positions us well relative to our full-year guidance ranges. Importantly, the major expansion taking place at our Rochester operation in Nevada remains on-track for a mid-year construction completion despite experiencing extreme winter weather during the first quarter. Even with the weather, Rochester’s operating results were ahead of plan and significantly stronger year-over-year, reflecting higher grades and throughput rates. With the second quarter representing the last quarter of elevated capital to complete the Rochester expansion and a balance sheet well-positioned to support this remaining investment, we look forward to an expected major inflection point during the second half of 2023 as production from Rochester begins to ramp up.

As Coeur celebrates its 95th birthday throughout 2023, the Company is well-positioned for an exciting and successful next chapter. Coupled with robust exploration and prudent capital investments aimed at extending mine lives across the rest of the portfolio, we believe Coeur offers a unique value proposition in our sector: an American silver and gold producer operating exclusively in North America with significant opportunities for growth over the near and long term.”

The first quarter production stronger than expected and in-line with 2023 guidance – Solid performances at Palmarejo, Rochester and Wharf offset lower production levels at Kensington, leading to total production of 69,039 ounces of gold and 2.5 million ounces of silver. Production levels are expected to increase during the second half of the year due to mine plan sequencing as well as the anticipated ramp-up and commissioning of the Rochester expansion.

Rochester expansion remains on-track for mid-year construction completion – Coeur began stacking ore on the new Stage VI leach pad and achieved mechanical completion of the new Merrill-Crowe process plant ahead of schedule during the first quarter. As of March 31, 2023, the project was 82% complete and approximately $634 million of the estimated project capital had been committed, of which $560 million had been incurred

Exploration success continues at Silvertip and Kensington – The deepest hole ever drilled at Silvertip targeting a magnetic anomaly and potential heat source was successfully completed during the quarter showing occurrences of intrusive porphyry and higher temperature mineralogy. Silvertip continues to impress with its high silver, zinc and lead grades as well as signs of other critical minerals such as indium, germanium and gallium contained in the deposit. At Kensington, drilling indicates that new mineralized zones identified in Upper Kensington continue, suggesting promising potential for further mine life increases.
