Coeur Mining — Oct 29, 2025 release

This program was completed at the end of August • Results from all programs support a meaningful expected contribution to year-end reserve and resource estimates Guidance • The Company has increased Wharf’s 2025 gold and silver production guidance ranges to reflect strong year-to-date performance and higher expected grades in the fourth quarter • Full-year 2025 production is expected to be 93,000 - 103,000 gold ounces (previously 90,000 - 100,000 ounces) and 100,000 - 150,000 ounces of silver (previously 50,000 - 200,000 ounces) • Adjusted CAS 1 in 2025 are expected to be $1,125 - $1,225 per gold ounce (previously $1,250 - $1,350 per ounce) 12 • Capital expenditures are expected to be $13 - $17 million, which is unchanged from the previous guidance range • Exploration investment in 2025 is expected to be $7 - $10 million (substantially all expensed), which is unchanged from the previous guidance range 13 Exploration The Company’s exploration investment in 2025 is expected to total $67 - $77 million for expansion drilling (classified as exploration expense) and $10 - $16 million for infill drilling (capitalized exploration) for a total expected investment of $77 - $93 million. Top exploration priorities for 2025 are: (1) continuing to build the inferred pipeline at Palmarejo to provide optionality to the operation, including to the east of existing operations outside the Franco-Nevada gold stream area of interest, where 60% of this year’s exploration investment is budgeted; (2) outlining higher-grade structures to enhance near-term margins and longer-term free cash flow profile of Rochester; (3) maintaining a 5-year reserve-based mine life at Kensington while finding higher-grade zones to enhance cash flow; (4) completing the expansion and infill programs at Wharf to add to the life of mine; (5) building on the new geological model and understanding at Silvertip to grow the resource base, and; (6) rapidly building detailed knowledge of Las Chispas and maintaining mine life. During the third quarter, Coeur invested approximately $30 million ($25 million expensed and $5 million capitalized), compared to roughly $30 million ($23 million expensed and $7 million capitalized) in the prior period. At Silvertip, exploration investment totaled approximately $10 million in the third quarter, compared to $9 million in the prior period, with up to five rigs drilli
