Such forward‐looking statements involve known and unknown risks, uncertainties, and other factors which may cause Coeur’s and SilverCrest’s respective 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 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 and SilverCrest’s respective 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 either Coeur or SilverCrest and any of their respective 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 and SilverCrest’s respective future acquisitions of new mining properties or businesses, the loss of access or insolvency of any third-party refiner or smelter to whom Coeur or SilverCrest markets their respective 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 and Silvercrest’s respective 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 reports on Form 10-K and Form 10-Q and SilverCrest’s annual information form for the year ended December 31, 2023. 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 and SilverCrest each disclaim any intent or obligation to update publicly such forward‐looking statements, whether as a result of new information, future events, or otherwise. Additionally, Coeur and SilverCrest each undertake no obligation to comment on analyses, expectations, or statements made by third parties in respect of each of Coeur and SilverCrest, their financial or operating results or their securities. The scientific and technical information concerning Coeur’s mineral projects in this presentation have been reviewed and approved by a “qualified person” under Item 1300 of SEC Regulation S-K, namely Coeur’s Senior Director, Technical Services, Christopher Pascoe. The scientific and technical information concerning SilverCrest’s mineral projects in this presentation have been reviewed and approved by a “qualified person” under National Instrument 43-101, being N. Eric Fier, CPG P. Eng and Chief Executive Officer for SilverCrest. For a description of the key assumptions, parameters and methods used to estimate mineral reserves and mineral resources included in this presentation that relate to Coeur’s mineral projects, 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 Coeur’s material properties which are available at www.sec.gov. 2023 and 2018 reserves and resources were determined in accordance with Item 1300 of SEC Regulation S-K. Additional details with respect to the Las Chispas mine project in Sonora, Mexico are available in SilverCrest’s technical report dated September 5, 2023 and in SilverCrest’s Annual Information Form for the year ended December 31, 2023, each filed on SilverCrest’s SEDAR+ profile at www.sedarplus.ca. 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 do not represent, and should not be construed to be, an estimate of a mineral resource or mineral reserve. This presentation includes reference to certain financial measures which are not standardized measures under the parties’ respective financial reporting frameworks. These measures include 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. The parties believe that these measures, together with measures determined in accordance with U.S. GAAP or IFRS, provide investors with an improved ability to evaluate the underlying performance of Coeur and SilverCrest. These measures are widely used in the mining industry as a benchmark for performance but do not have any standardized meaning prescribed under U.S. GAAP orIFRS, and therefore they may not be comparable to similar measures disclosed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with U.S. GAAP or IFRS. Further details on these non-U.S. GAAP or non-IFRS financial performance measures are disclosed in Coeur’s MD&A accompanying its financial statements filed periodically on EDGAR at www.sec.gov. and SilverCrest’s MD&A accompanying its financial statements filed periodically on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov. This presentation is not, and under no circumstances is to be construed as, an advertisement or public offering of the securities referred to in this presentation. No securities commission or similar authority in United States or Canada has reviewed or in any way passed upon this presentation or the merits of the securities described herein and any representation to the contrary is an offence.

Reserves and Resources (cont.) NYSE: CDE NYSE: CDE NYSE: CDE 30 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. Wharf Mineral Reserve estimates use the following key input parameters: assumption of conventional open pit mining; reported above a gold cut-off grade of 0.010 oz/ton Au; average metallurgical recovery assumption of 79.0%; royalty burden of US$64/oz Au; pit slope angles that vary from 34–50º; mining costs of US$2.44/ton mined, process costs of US$11.71/ton processed (includes general and administrative costs). Rounding of short tons, grades, and troy ounces, as required by reporting guidelines, may result in apparent differences between tons, grades, and contained metal contents.

Reserves and Resources (cont.) NYSE: CDE NYSE: CDE NYSE: CDE 30 2018 Inferred Mineral Resources Notes to 2018 mineral reserves and resources: Effective December 31, 2018. Assumed metal prices for Mineral Reserves were $17.00 per ounce of silver, $1,250 per ounce of gold, $1.25 per pound zinc, $1.00 per pound lead. Assumed metal prices for estimated Mineral Resources were $20.00 per ounce of silver, $1,400 per ounce of gold, $1.30 per pound zinc, $1.05 per pound lead, except Lincoln Hill and Wilco at $1,350 per ounce gold and $22.00 per ounce silver. Mineral Resources are in addition to Mineral Reserves and do not have demonstrated economic viability. Inferred Mineral Resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be considered for estimation of Mineral Reserves, and there is no certainty that the Inferred Mineral Resources will be realized. The preliminary economic assessment for the re-scoped mine plan at Kensington is preliminary in nature and includes Inferred Mineral Resources, and does not have as high a level of certainty as a plan that was based solely on proven and probable reserves and there is no certainty that the results from the preliminary economic assessment will be realized. Rounding of tons and ounces, as required by reporting guidelines, may result in apparent differences between tons, grade, and contained metal content.

The Mineral Reserve is estimated using the 2019 CIM Estimation of Mineral Resources & Mineral Reserves Best Practice Guidelines and 2014 CIM Definition Standards for Mineral Resources & Mineral Reserves. The Mineral Reserve is estimated with a 372 gpt AgEq fully loaded COG for the deposit and an 85 gpt AgEq Marginal COG for development. The Mineral Reserve is estimated using long-term prices of $1,650/oz for gold and $21.00/oz for silver. A government gold royalty of 0.5% is included in the Mineral Reserve estimates. Stockpile values were provided by SilverCrest and account for approximately 7% of mineral reserve ounces. The Mineral Reserve is estimated with a maximum mining recovery of 95%, with reductions in select areas based on geotechnical guidelines. The Mineral Reserve presented includes both internal and external dilution. The external dilution includes a mining dilution of 0.5 m width on both the hanging wall and footwall for the long hole mining method (1 m total), and a 0.2 m width on both the hanging wall and footwall for the resue mining methods (0.4 m total). Cut-and-fill mining was assumed as breasting in all cases, using the ore sill drive width of 3.3 m as a minimum mining width inclusive of dilution. Additional external dilution was applied in select areas based on geotechnical recommendations. Backfill dilution is also included and represents 4% for the long hole mining method and 7% for cut-and-fill and resue mining methods. A minimum mining width of 1.5 m, 3.3 m and 0.5 m was used for the long-hole, cut-and-fill and resue mining methods, respectively. Average metallurgical recoveries applied are 97.9% Au and 96.7% Ag. The economic viability of the Mineral Reserve has been demonstrated. AgEq(gpt) = (Au(gpt) * 79.51 + Ag(gpt)). AgEq calculations consider metal prices, metallurgical recoveries, Mexican Government gold royalty and tax rate. Estimates use metric units (metres (m), tonnes (t), and gpt). Metal contents are presented in troy ounces (metric tonne x grade / 31.103475). The independent Qualified Person is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issue that could materially affect the Mineral Reserve Estimate.

The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It can be reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration. The Mineral Resources in the Report were estimated using the 2019 CIM Estimation of Mineral Resources & Mineral Reserves Best Practice Guidelines and 2014 CIM Definition Standards for Mineral Resources & Mineral Reserves. Historical mined areas were removed from the wireframes and block model. AgEq is based on gold to silver ratio of 86.9:1 calculated using $1,410/oz Au and $16.60/oz Ag, with average metallurgical recoveries of 96% Au and 94% Ag. Mineral Resources are inclusive of the Mineral Reserves stated in Section 15. Totals may not add due to rounding.
