Such forward‐looking statements involve known and unknown risks, uncertainties, and other factors which may cause Coeur’s and New Gold’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 necessary approvals of Coeur’s stockholders and New Gold’s shareholders may not be obtained, that required regulatory approvals or any other condition to closing of the transaction may not be satisfied, the risk that the closing of the transaction may be delayed or not occur at all, the ultimate timing, outcome and results of integrating the operations of Coeur and New Gold, changes in governmental regulations or enforcement practices, as well as 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, silver and copper and a sustained lower price or higher treatment and refining charge environment, the uncertainties inherent in Coeur’s and New Gold’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 New Gold 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 New Gold’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 New Gold 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 New Gold’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 New Gold’s annual information form for the year ended December 31, 2024. 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 New Gold 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 New Gold each undertake no obligation to comment on analyses, expectations, or statements made by third parties in respect of each of Coeur and New Gold, 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 Vice President, Technical Services, Christopher Pascoe. The scientific and technical information concerning New Gold’s mineral projects in this presentation have been reviewed and approved by a “qualified person” under National Instrument 43-101, being Travis Murphy, Vice President, Operations for New Gold. 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. Additional details with respect to New Gold’s New Afton and Rainy River mine projects are available in New Gold’s technical reports both dated February 10, 2025, and in New Gold’s Annual Information Form for the year ended December 31, 2024 , each filed on New Gold’s SEDAR+ profile at www.sedarplus.ca. Coeur’s 2024, 2023, 2022, and 2021 reserves and resources were determined in accordance with Item 1300 of SEC Regulation S-K. Reserves and resources for certain prior periods, including 2019, 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 operating cash flow less capital expenditures, adjusted EBITDA, adjusted EBITDA margin, free cash flow, free cash flow per share,. The parties believe that these measures, together with measures determined in accordance with GAAP or IFRS, provide investors with an improved ability to evaluate the underlying performance of Coeur and New Gold. These measures are widely used in the mining industry as a benchmark for performance but do not have any standardized meaning prescribed under IFRS, 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 GAAP or IFRS. Further details on these non-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 New Gold’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. All references to $ are US dollar denominated unless otherwise noted.

Reserves and Resources (cont.) Notes to 2024 Mineral Reserves: The Mineral Reserve estimates are current as of December 31, 2024 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 2024 Mineral Reserves were $23.50 per ounce of silver, $1,800 per ounce of gold, $1.15 per pound of zinc, $0.95 per pound of lead, except for Kensington at $2,000 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 2.13–2.45 g/t AuEq and an incremental development cut-off grade 1.05 g/t AuEq; metallurgical recovery assumption of 92.0% for gold and 83.0% for silver; mining dilution assumes 0.3–1.5 meter of hanging/foot wall waste dilution; mining loss of 15% was applied; variable mining costs that range from US$57.67–US$74.45/tonne, surface haulage costs of US$4.29/tonne, process costs of US$31.06/tonne, general and administrative costs of US$15.95/tonne, and surface/auxiliary support costs of US$4.42/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 $3.76/ton oxide and US$3.86/ton sulfide; Nevada Packard oxide recovery Au = 92.0% and Ag = 61.0%; with a net smelter return cutoff of $4.24/ton for oxide; Lincoln Hill oxide recovery Au = 63.9% and Ag = 39.5%; with a net smelter return cutoff of $4.53/ton for oxide where the NSR is calculated as resource net smelter return (NSR) = silver grade (oz/ton) * silver recovery (%) * (silver price ($/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 $2,000/oz; reported above a gold cut-off grade of 0.133 oz/ton Au; metallurgical recovery assumption of 94.2%; gold payability of 97.5%; mining dilution of 15-20%; mining loss of 12% was applied; mining costs of US$116.09/ton mined; process costs of US$55.14/ton processed; general and administrative costs of US$53.18/ton processed; sustaining capital US$4.50/ton processed; and concentrate refining and shipping costs of US$97.48/oz sold.

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.) Notes to 2024 Mineral Resources: Mineral Resource estimates are reported exclusive of Mineral Reserves, are current as of December 31, 2024, 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 2024 estimated Mineral Resources were $27.00 per ounce of silver, $2,100 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 1.83–2.10 g/t AuEq; metallurgical recovery assumption of 92.0% for gold and 83.0% for silver; variable mining costs that range from US$57.67–US$74.45/tonne, surface haulage costs of US$4.29/tonne, process costs of US$31.06/tonne, general and administrative costs of US$15.95/tonne, and surface/auxiliary support costs of US$4.42/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: Mineral Resource estimates use the following key input parameters: metal price of $2,300 per ounce gold, assumption of conventional longhole underground mining; reported above a variable gold cut-off grade of 0.115 oz/ton Au; metallurgical recovery assumption of 94.2%; gold payability of 97.5%, mining costs of US$116.09/ton mined; process costs of US$55.14/ton processed; general and administrative costs of US$53.18/ton processed; sustaining capital US$4.50/ton processed; and concentrate refining and shipping costs of US$97.48/oz sold. Wharf Mineral Resource estimates use the following key input parameters: assumption of conventional open pit mining; reported above a gold cut-off grade of 0.008 oz/ton Au; average metallurgical recovery assumption of 78.0% across all rock types; royalty burden of US$140.40/oz Au; pit slope angles that vary from 34–50º; mining costs of $2.56/ton mined, and process costs of US$12.02/ton processed (includes general & administrative and sustaining capital costs). 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 $3.76/ton oxide and US$3.86/ton sulfide; Nevada Packard oxide recovery Au = 92.0% and Ag = 61.0%; with a net smelter return cutoff of $4.24/ton for oxide; Lincoln Hill oxide recovery Au = 63.9% and Ag = 39.5%; with a net smelter return cutoff of $4.53/ton for oxide, where the NSR is calculated as resource net smelter return (NSR) = silver grade (oz/ton) * silver recovery (%) * (silver price ($/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 estimates 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. 2023 metal prices were used to determine the mineral resource which were $25.00 per ounce of silver, $1.30 per pound of zinc, $1.00 per pound of lead. Wilco Open Pit Mineral Resource estimates are reported using an equivalent gold cutoff of 0.20 ounces per ton assuming a silver to gold ratio of 60:1. Resources are reported in-situ and contained withed a conceptual measured, indicated and inferred optimized pit shell. Silver price of US$20/oz, gold price of US$1,400/oz. Average oxide and sulfide gold recovery is 70%, average carbonaceous gold recovery is 50%. Average oxide and sulfide gold recovery is 60%. Average carbonaceous silver recovery is 50%. Open pit mining cost is US$1.50/ton, processing and processing and G&A cost is US$5.46/ton; average pit slope angles of 50º. 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 resources 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 report is considered current and is presented unchanged.

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.

Reserves and Resources (cont.) 2019 Inferred Mineral Resources Notes to 2019 mineral reserves and resources: Effective December 31, 2019. Assumed metal prices for Mineral Reserves were $17.00 per ounce of silver, $1,350 per ounce of gold, $1.15 per pound zinc, $0.95 per pound lead. Assumed metal prices for estimated Mineral Resources were $20.00 per ounce of silver, $1,500 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, and Sterling at $1,200 per ounce of gold. 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. For details on the estimation of mineral resources and reserves, including the key assumptions, parameters and methods used to estimate the Mineral Resources and Mineral Reserves, Canadian investors should refer to the NI 43-101 Technical Reports for Coeur's properties on file at www.sedar.com.
