Coeur Mining — Nov 6, 2024 release

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. The Company expects to invest $11 - $14 million in exploration at Silvertip in 2024, which excludes $15 - $20 million related to underground mine development and site support costs. The objectives of the 2024 exploration program at Silvertip are to: (1) grow the known mineralized structures such as the Southern Silver zone from underground drilling focusing on along-strike and down-dip potential that has been identified; (2) drill much larger step-outs on major structures using surface drilling with a key focus on the Southern Silver, Saddle and Camp Creek zones; and (3) carry out district-scale field work to identify Silvertip lookalikes and other large structures with potential to host large ore bodies and to identify the outer limits of this large system. This three-pronged approach is progressing well with surface mapping and sampling completed during the quarter, surface drilling with two rigs were completed at the end of October and one underground drill rig continuing in November. 11 2024 Guidance Production during the third quarter was in-line with Coeur’s expectations, leading the Company to reaffirm 2024 production and cost guidance. The below exploration expense guidance excludes $15 - $20 million of underground mine
