Coeur Mining — Nov 6, 2024 release

Year-over-year production for the quarter increased 48% Financial • Adjusted CAS 1 on a by-product basis increased 8% quarter-over-quarter to $885 per ounce, largely driven by decreasing favorable recoveries on legacy pads from the prior period • Capital expenditures increased slightly quarter-over-quarter to approximately $3 million • Free cash flow 1 in the third quarter totaled an all-time high $49 million compared to $16 million in the prior period, reflecting higher gold sales Exploration • Exploration investment during the quarter totaled $2 million (substantially all expensed) compared to $1 million (substantially all expensed) in the prior quarter • Increased exploration investment during the quarter was mainly driven by an expanded program that commenced after opportunities were recognized to meaningfully extend the mine life at Wharf 9 • Two rigs were active during the quarter at the Juno and North Foley deposits undertaking infill and expansion drilling Guidance • Full-year 2024 production is expected to be 86,000 - 96,000 gold ounces • CAS 1 in 2024 are expected to be $950 - $1,050 per gold ounce • Capital expenditures are expected to be $5 - $7 million 10 Exploration The Company’s exploration investment in 2024 is expected to total $40 - $50 million for expansion drilling (classified as exploration expense) and $15 - $20 million for infill drilling (capitalized exploration). Top exploration priorities for the Company’s 2024 exploration program include: (1) building reserves and extending mine life at Kensington to over five years by year-end; (2) pursuing higher grade structures at Rochester to enhance the near-term margin and cash flow profile of the newly-expanded operation; (3) building out a robust pipeline of inferred resources at Palmarejo to potentially drive future reserve growth; (4) further extending Wharf’s reserve-based mine life; and (5) expanding and enhancing the understanding of the evolving world-class polymetallic Silvertip system located in British Columbia. During the third quarter, Coeur invested approximately $25 million ($20 million expensed and $5 million capitalized), compared to roughly $18 million ($13 million expensed and $5 million capitalized) in the prior period. At Silvertip, exploration investment totaled approximately $9 million in the third quarter, compared to $6 million in the prior period.
