Coeur Mining — May 7, 2025 release

Drilling to date has been concentrated on expanding the mineralized zones at Juno and North Foley and is outlining a new zone of mineralization in the Wedge - a previously un-drilled target to the southeast of the North Foley deposit Guidance • Full-year 2025 production is expected to be 90,000 - 100,000 gold ounces and 50,000 - 200,000 ounces of silver • Adjusted CAS 1 in 2025 are expected to be $1,250 - $1,350 per gold ounce • Capital expenditures are expected to be $13 - $17 million, which reflects increased infill drilling expected to materially extend the mine life as well as other investments which are expected to be required to convert the Juno and North Foley deposits into reserves • Exploration investment in 2025 is expected to be $7 - $10 million (substantially all expensed) 12 Exploration During the first quarter, Coeur invested approximately $22 million ($20 million expensed and $2 million capitalized), compared to roughly $20 million ($17 million expensed and $4 million capitalized) in the prior period. 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). 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, where 60% of this year’s exploration investment is budgeted; (2) outlining higher-grade structures to enhance the near-term margin 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 bolster 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 rapidly grow the resource base, and; (6) rapidly building detailed knowledge of Las Chispas and maintaining mine life. At Silvertip, exploration investment totaled approximately $6 million in the first quarter, compared to $6 million in the prior period. The Company expects 2025 Silvertip exploration investment to be approximately $12 - $14 million, which excludes $17 - $22 million related to underground mine developme
