To: Coeur Employees

Dear team,

I am pleased to share that we announced the signing of a definitive agreement to acquire Vancouver-based SilverCrest Metals Inc this morning. SilverCrest operates the Las Chispas underground mine, one of the world's highest-grade, lowest-cost silver and gold operations located in Sonora, Mexico.

Upon closing, we expect this acquisition to add meaningful, immediate, and high-quality production and cash flow to our Company. Together with the silver production from Rochester and Palmarejo, the addition of Las Chispas positions Coeur Mining as a leading global silver company. The addition of the Las Chispas mine is also expected to improve our cost profile, materially increase our free cash flow, and allow us to accelerate our debt reduction initiatives. You may view key benefits of this transaction in our press release found here: https://www.coeur.com/investors/news/default.aspx

With this acquisition, we will welcome approximately 300 employees and 700 contractors from the Las Chispas team into the Coeur organization. The Las Chispas team has done an outstanding job responsibly advancing from discovery to stable production in nine years. Similar to Coeur's community and environmental stewardship, the Las Chispas team has taken significant measures to support local communities through water infrastructure planning, advancing solar initiatives, and actively partnering with local, state, and federal agencies, as well as nearby farmers and ranchers.

As we continue to work toward the transaction's expected closing in the first quarter of 2025, our management team remains committed to collaborating with the SilverCrest team for a seamless integration.

For our Coeur employees, in and outside of Mexico, it's important to note that this acquisition does not impact the operations at any of our US, Canadian or Mexican sites.

A broad group of individuals has worked tirelessly to allow us to make today's announcement. These individuals have directly impacted the exciting future of our Company, and I am sincerely grateful for their efforts.

I look forward to sharing more information with you as we progress through relevant approvals and approach the closing. In the meantime, please reach out to your manager with any questions or send inquiries to [email protected].

Sincerely,

Mitch

Cautionary Note to U.S. Investors

Coeur's public disclosures are governed by the U.S. Securities Exchange Act of 1934, as amended, including Regulation S-K 1300 thereunder, whereas SilverCrest discloses estimates of "measured," "indicated," and "inferred" mineral resources as such terms are used in the JORC Code and Canada's National Instrument 43-101. Although S-K 1300, the JORC Code, and NI 43-101 have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, they at times embody different approaches or definitions. Consequently, investors are cautioned that public disclosures by SilverCrest prepared in accordance with the JORC Code or NI 43-101 may not be comparable to similar information made public by companies, including Coeur, subject to S-K 1300 and the other reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder. The scientific and technical information concerning Coeur's mineral projects in this communication 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 SilverCrest "qualified person" under NI 43-101 for this communication is N. Eric Fier, CPG, P.Eng, CEO for SilverCrest, who has reviewed and approved its contents.
