Rochester silver and gold production increased 50% and 79%, respectively, compared to the second quarter of 2024 and remains on track to deliver on its full-year guidance ranges • Reaffirming full-year production and cost guidance - Coeur remains positioned to deliver guided 2025 production of 380,000 - 440,000 ounces of gold and 16.7 - 20.3 million ounces of silver, which 1 represent year-over-year expected increases of 20% and 62% for gold and silver, respectively 3 . The Company also reaffirmed its full-year CAS 1 guidance “Coeur’s record second quarter reflects strong contributions from all five of our North American gold and silver operations, including the first full quarter from the recently acquired Las Chispas mine,” said Mitchell J. Krebs, Chairman, President and Chief Executive Officer. “Together with the benefit of higher gold and silver prices, we saw a step change in our financial results in the quarter, including an impressive $146 million of free cash flow, while we eliminated the remaining balance on our RCF 2 and began buying back shares.” “Looking ahead to the second half of the year, we expect even higher gold and silver production levels consistent with our re-affirmed 2025 production and cost guidance. We remain uniquely positioned to leverage higher gold and silver prices, which is expected to lead to over $800 million of full-year 2025 adjusted EBITDA and over $400 million of full-year 2025 free cash flow.” 2 Financial and Operating Highlights (Unaudited) (Amounts in millions, except per share amounts, gold o
