NYSE: CDE 2024 Proxy Statement Highlights April 2024

Cautionary Statements NYSE: CDE NYSE: CDE 2 This presentation contains forward‐looking statements within the meaning of securities legislation in the United States and Canada, including statements involving strategic priorities and company strategies, environmental, social and governance (“ESG”) initiatives, expectations and initiatives at Palmarejo, Rochester, Kensington, Wharf and Silvertip, including the Rochester expansion project, and mineral reserve and resource estimates. Such forward‐looking statements involve known and unknown risks, uncertainties, and other factors which may cause Coeur's actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward‐looking statements. Such factors include, among others, the risk that the Rochester expansion project takes longer than expected to ramp up to full production rates, the risk that anticipated production, cost and expense levels are not attained, the risks and hazards inherent in the mining business (including risks inherent in developing and expanding large-scale mining projects, environmental hazards, industrial accidents, weather or geologically-related conditions), changes in the market prices of gold and silver and a sustained lower price or higher treatment and refining charge environment, the uncertainties inherent in Coeur’s production, exploration and development activities, including risks relating to permitting and regulatory delays, mining law changes, ground conditions, grade and recovery variability, any future labor disputes or work stoppages (involving the Company and its subsidiaries or third parties), the risk of adverse outcomes in litigation, the uncertainties inherent in the estimation of mineral reserves and resources, impacts from Coeur’s future acquisition of new mining properties or businesses, the loss of access or insolvency of any third-party refiner or smelter to whom Coeur markets its production, materials and equipment availability, inflationary pressures, continued access to financing sources, the effects of environmental and other governmental regulations and government shut-downs, the risks inherent in the ownership or operation of or investment in mining properties or businesses in foreign countries, Coeur’s ability to raise additional financing necessary to conduct its business, make payments or refinance its debt, as well as other uncertainties and risk factors set out in filings made from time to time with the United States Securities and Exchange Commission, and the Canadian securities regulators, including, without limitation, Coeur’s most recent report on Form 10-K. Actual results, developments, and timetables could vary significantly from the estimates presented. Readers are cautioned not to put undue reliance on forward looking statements. Coeur disclaims any intent or obligation to update publicly such forward‐looking statements, whether as a result of new information, future events, or otherwise. Additionally, Coeur undertakes no obligation to comment on analyses, expectations, or statements made by third parties in respect of Coeur, its financial or operating results or its securities. The scientific and technical information concerning our mineral projects in this presentation have been reviewed and approved by a “qualified person” under Item 1300 of SEC Regulation S- K, namely our Senior Director, Technical Services, Christopher Pascoe. For a description of the key assumptions, parameters and methods used to estimate mineral reserves and mineral resources included in this presentation, as well as data verification procedures and a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, sociopolitical, marketing or other relevant factors, please review the Technical Report Summaries for each of the Company’s material properties which are available at www.sec.gov. 2023 reserves and resources were determined in accordance with Item 1300 of SEC Regulation S-K. Reserves and resources for certain prior periods were determined in accordance with Canadian National Instrument 43-101. Both sets of reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but the standards embody slightly different approaches and definitions. The ranges of potential tonnage and grade (or quality) of the exploration results described in this presentation are conceptual in nature. There has been insufficient exploration work to estimate a mineral resource. It is uncertain if further exploration will result in the estimation of a mineral resource. The exploration results described in this presentation therefore does not represent, and should not be construed to be, an estimate of a mineral resource or mineral reserve. Non‐U.S. GAAP Measures ‐ We supplement the reporting of our financial information determined under United States generally accepted accounting principles (U.S. GAAP) with certain non‐U.S. GAAP financial measures, including adjusted net income (loss), operating cash flow before changes in working capital, adjusted EBITDA, adjusted EBITDA margin, total leverage, net leverage, free cash flow, adjusted costs applicable to sales per ounce/pound and adjusted liquidity. We believe that these adjusted measures provide meaningful information to assist management, investors and analysts in understanding our financial results and assessing our prospects for future performance. We believe these adjusted financial measures are important indicators of our recurring operations because they exclude items that may not be indicative of, or are unrelated to our core operating results, and provide a better baseline for analyzing trends in our underlying businesses. We believe adjusted net income (loss), adjusted EBITDA, adjusted EBITDA margin, total leverage, net leverage, free cash flow, adjusted costs applicable to sales per ounce/pound and adjusted liquidity are important measures in assessing the Company's overall financial performance. This presentation does not represent an offer of any securities for sale.

Cautionary Statements NYSE: CDE NYSE: CDE 2 Mineral Reserves and Resources Coeur is subject to the reporting requirements of the Exchange Act and applicable Canadian securities laws, and as a result we report our mineral reserves and mineral resources according to two different standards. U.S. reporting requirements, are governed by Item 1300 of Regulation S-K (‘‘S-K 1300’’), as issued by the U.S. Securities and Exchange Commission (‘‘SEC’’). Canadian reporting requirements for disclosure of mineral properties are governed by National Instrument 43-101 Standards of Disclosure for Mineral Projects (‘‘NI 43-101’’), as adopted from the definitions provided by the Canadian Institute of Mining, Metallurgy and Petroleum. Both sets of reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but the standards embody slightly different approaches and definitions. In Coeur’s public filings in the U.S. and Canada and in certain other announcements not filed with the SEC, we disclose proven and probable reserves and measured, indicated and inferred resources, each as defined in S-K 1300. The estimation of measured resources and indicated resources involves greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves, and therefore investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into S-K 1300- compliant reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources, and therefore it cannot be assumed that all or any part of inferred resources will ever be upgraded to a higher category. Therefore, investors are cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically.

2023 Performance Highlights In 2023, Coeur was once again a leader among peers in key safety performance metrics, delivered strong operating results and continued to navigate the impacts of inflation on costs and profitability. The Company also completed construction of the expansion project at Rochester, which is expected to transform Rochester into a cornerstone asset through significant increases in production and cash flow over a long mine life of ~16 years based on 2023 year-end reserves. In addition, Coeur achieved strong results from its expansion-focused exploration program in 2023, including significant increases in inferred resources and measured and indicated resources, and reserve growth at Kensington for the second consecutive year, reflecting the results of the multi- year enhanced development and drilling program at Kensington aimed at extending its mine life NYSE: CDE NYSE: CDE 10

2023 Compensation Results Aligned with Performance (cont.) NYSE: CDE NYSE: CDE 10

2023 Executive Compensation – Realized Pay Coeur’s multiyear performance-linked pay aligned with stockholder returns Our NEO compensation program is structurally designed to be a strong performance-based program. In the case of the CEO, 81% of his target compensation is performance-based or “at-risk”; only 19% is fixed, delivered through base salary. This graph demonstrates alignment by showing three-year target value for performance and “at-risk” elements as well as the actual value realized from those compensation elements, equal to actual 2021-2023 AIP, plus the value of the PSUs for the 2021-2023 performance period that paid out in early 2023, valued as of December 31, 2023, the last date of the performance period, plus the value of restricted stock granted in 2021, 2022 and 2023, valued as of December 31, 2023, including shares not yet vested. The CEO’s actual value of compensation from performance based and “at-risk” elements was 38% lower than the target value. During this same period, our stock price decreased by 69%. We believe this demonstrates alignment of pay and performance. NYSE: CDE NYSE: CDE 10

Reserves and Resources (cont.) NYSE: CDE NYSE: CDE 32 Notes to 2023 Mineral Reserves: The Mineral Reserve estimates are current as of December 31, 2023 and are reported using the definitions in Item 1300 of Regulation S–K (17 CFR Part 229) (SK1300) and were prepared by the company’s technical staff. Assumed metal prices for 2023 Mineral Reserves were $21.00 per ounce of silver, $1,600 per ounce of gold, $1.15 per pound of zinc, $0.95 per pound of lead, except for Kensington at $1,850 per ounce of gold. Palmarejo Mineral Reserve estimates use the following key input parameters: assumption of conventional longhole underground mining; reported above a variable gold equivalent cut-off grade that ranges from 2.11–2.97 g/t AuEq and an incremental development cut-off grade ranging from 1.16–1.55 g/t AuEq; metallurgical recovery assumption of 92.0% for gold and 83.0% for silver; mining dilution assumes 0.4–1.1 meter of hanging/foot wall waste dilution; mining loss of 15% was applied; variable mining costs that range from US$44.72–US$85.71/tonne, surface haulage costs of US$4.92/tonne, process costs of US$32.70/tonne, general and administrative costs of US$14.06/tonne, and surface/auxiliary support costs of US$3.18/tonne. Excludes the impact of the Franco-Nevada gold stream agreement at Palmarejo in calculation of Mineral Reserves. No assurances can be given that all mineral reserves will be mined, as mineralized material that may qualify as reserves under applicable standards by virtue of having positive economics may not generate attractive enough returns to be included in our mine plans, due to factors such as the impact of the gold stream at Palmarejo. As a result, we may elect not to mine portions of the mineralized material reported as reserves. Rochester Mineral Reserve estimates are tabulated within a confining pit design and use the following input parameters: Rochester oxide variable recovery Au = 77.7–85.9% and Ag = 59.4-61.0%; Rochester sulfide variable recovery Au = 15.2–77.7% and Ag = 0.0–59.4%; with a net smelter return cutoff of $3.01/st oxide and US$3.11/st sulfide; Nevada Packard oxide recovery Au = 92.0% and Ag = 61.0%; with a net smelter return cutoff of $5.51/st for oxide, where the NSR is calculated as resource net smelter return (NSR) = silver grade (oz/ton) * silver recovery (%) * (silver price ($/oz) - refining cost ($/oz)) + gold grade (oz/ton) * gold recovery (%) * (gold price ($/oz) - refining cost ($/oz)); variable pit slope angles that approximately average 48º over the life-of-mine. Kensington Mineral Reserve estimates use the following key input parameters: assumption of conventional underground mining; gold price of $1,850/oz; reported above a gold cut-off grade of 0.135 oz/st Au; metallurgical recovery assumption of 93.5%; gold payability of 97.5%; mining dilution of 20%; mining loss of 12% was applied; mining costs of US$103.67/ton mined; process costs of US$55.06/ton processed; general and administrative costs of US$55.37/ton processed; Sustaining capital US$4.50/ton processed; and concentrate refining and shipping costs of US$108.67/oz sold.

Reserves and Resources (cont.) NYSE: CDE NYSE: CDE 32 Notes to 2023 Mineral Resources: Mineral Resource estimates are reported exclusive of Mineral Reserves, are current as of December 31, 2023, and are reported using definitions in SK1300 on a 100% ownership basis. Mineral Resource estimates were prepared by the Company’s technical staff. Assumed metal prices for 2023 estimated Mineral Resources were $25.00 per ounce of silver, $1,800 per ounce of gold, $1.30 per pound of zinc, $1.00 per pound of lead, unless otherwise noted. Palmarejo Mineral Resource estimates use the following key input parameters: Assumption of conventional longhole underground mining; reported above a variable gold equivalent cut-off grade that ranges from 1.87–2.64 g/t AuEq; metallurgical recovery assumption of 92.0% for gold and 83.0% for silver; variable mining costs that range from US$44.72–US$85.71/tonne, surface haulage costs of US$4.92/tonne, process costs of US$32.70/tonne, general and administrative costs of US$14.06/tonne, and surface/auxiliary support costs of US$3.18/tonne. Excludes the impact of the Franco-Nevada gold stream agreement at Palmarejo in calculation of Mineral Resources. Kensington Mineral Resource estimates use the following key input parameters: metal price of $2,000 per ounce gold, assumption of conventional longhole underground mining; reported above a variable gold cut-off grade of 0.124 oz/ton Au; metallurgical recovery assumption of 93.5%; gold payability of 97.5%, mining costs of US$103.67/ton mined; process costs of US$55.06/ton processed; general and administrative costs of US$55.37/ton processed; Sustaining capital US$4.50/ton processed; and concentrate refining and shipping costs of US$108.67/oz sold.

(6) Rochester Mineral Resource estimates are tabulated within a confining pit shell and use the following input parameters: Rochester oxide variable recovery Au = 77.7–85.9% and Ag = 59.4%; Rochester sulfide variable recovery Au = 15.2–77.7% and Ag = 0.0–59.4%; with a net smelter return cutoff of $3.01/st oxide and US$3.11/st sulfide; Nevada Packard oxide recovery Au = 92.0% and Ag = 61.0%; with a net smelter return cutoff of $5.51/st for oxide, where the NSR is calculated as resource net smelter return (NSR) = silver grade (oz/ton) * silver recovery (%) * (silver price ($/oz) - refining cost ($/oz)) + gold grade (oz/ton) * gold recovery (%) * (gold price ($/oz) - refining cost ($/oz)); variable pit slope angles that approximately average 48º over the life-of-mine. Silvertip Underground Mineral Resource estimates are reported using a net smelter return (“NSR”) cutoff of US$130/tonne. Mineral Resources are reported insitu using the following assumptions: The estimate use the following key input parameters: lead recovery of 89-90%, zinc recovery of 82-83% and silver recovery of 83- 84%. Lead concentrate grade of 53-54%; zinc concentrate grade of 56-57%; mining costs of US$68.77/tonne; processing costs of US$58.20/tonne and US$46.49/tonne, where the NSR ($/tonne) = tonnes x grade x metal prices x metallurgical recoveries – royalties – TCRCs – transport costs over the life of the mine. Lincoln Hill Open Pit Mineral Resource estimates are reported in-situ and are contained within a confining pit shell and use the following key input parameters: reported above an oxide gold equivalent cutoff of 0.15 ounces per ton and 0.20 oz ounces per ton assuming a silver to gold ratio of 60:1; gold recoveries of 64%; silver recoveries of 59%; mining costs of US$3.10/ton; process costs of US$3.60/ton; general and administrative costs of $1.50/ton processed; average pit slope angles of 45º over the life-of-mine. The technical and economic parameters are those that were used in the 2018 Resource Estimation. Based on the QPs review of the estimate, there would be no material change to the Mineral Resource if a gold price of US$1,700/oz, a silver price of US$22/oz or economic parameters were updated. Therefore the 2018 Mineral Resource is considered current and is presented unchanged.
