**To:** Coeur Employees

**From:** Mitch Krebs

**Date:** November 3, 2025

**EMAIL SUBJECT LINE:** Coeur Announces Acquisition of New Gold

Dear Coeur Team,

I am pleased to share that we announced the signing of a definitive agreement to acquire Toronto-based New Gold Inc. this morning. New Gold operates the Rainy River, gold-silver mine in Ontario, Canada and the New Afton gold-copper mine in British Colombia, Canada. The transaction creates a company with approximately $20 billion combined market capitalization and seven North American operations.

Upon closing, we expect this acquisition to create an unrivaled, all-North-American precious metals mining powerhouse. As a combined company in 2026, we expect to generate approximately $3 billion of EBITDA and approximately $2 billion of free cashflow, at lower overall costs and higher margins. You may view key benefits of this transaction in our press release that is attached.

With this acquisition, we will welcome approximately 1,700 employees and 450 contractors into the Coeur organization. Similar to Coeur, the New Gold team has a strong people-focused and safety-first culture, which is demonstrated in their 'Courage to Care' company values. We look forward to learning more about best practices from their operations as we integrate and grow together. The retention of their talented team will be critical for us to realize the full value of this transaction.

As we continue to work toward the transaction's expected closing in the first half of 2026, our management team remains committed to collaborating with the New Gold team for a seamless integration. For our Coeur employees, in and outside of Canada, it's important to note that this acquisition does not impact the operations at any of our existing sites.

I am truly grateful to each of you and the performance across our entire organization that has built the strong foundation to enable us to pursue this transaction. And a special thank you to the group of individuals who worked tirelessly to allow us to make today's announcement and will continue to assist with integration. Our people at Coeur are the reason for the exciting future of our Company.

I look forward to sharing more information with you as we progress through relevant approvals and approach the completion of this transformative transaction next year.

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 New Gold discloses estimates of "measured," "indicated," and "inferred" mineral resources as such terms are used in Canada's National Instrument 43-101. Although S-K 1300 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 New Gold prepared in accordance with 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 Vice President, Technical Services, Christopher Pascoe. New Gold's "qualified person" under NI 43-101 for this communication is Travis Murphy, Vice President, Operations who has reviewed and approved its contents.

These forward-looking statements involve significant risks and uncertainties that could cause actual results to differ materially from those anticipated, including, but not limited to, the possibility that shareholders of New Gold may not approve the Transaction or stockholders of Coeur may not approve the Stock Issuance or the Charter Amendment; the risk that any other condition to closing of the Transaction may not be satisfied; the risk that the closing of the Transaction might be delayed or not occur at all; the anticipated timing of mailing proxy statements and information circulars regarding the Transaction; the risk that the either Coeur or New Gold may terminate the Arrangement Agreement and either Coeur or New Gold is required to pay a termination fee to the other party; potential adverse reactions or changes to business or employee relationships of Coeur or New Gold, including those resulting from the announcement or completion of the Transaction; the diversion of management time on transaction-related issues; the ultimate timing, outcome and results of integrating the operations of Coeur and New Gold; the effects of the business combination of Coeur and New Gold, including the combined company's future financial condition, results of operations, strategy and plans; the ability of the combined company to realize anticipated synergies in the timeframe expected or at all; changes in capital markets and the ability of the combined company to finance operations in the manner expected; the risk that Coeur or New Gold may not receive the required stock exchange and regulatory approvals of the Transaction; the expected listing of shares on the NYSE and TSX; the risk of any litigation relating to the proposed Transaction; the risk of changes in governmental regulations or enforcement practices; the effects of commodity prices, life of mine estimates; the timing and amount of estimated future production; the risks of mining activities; and the fact that operating costs and business disruption may be greater than expected following the public announcement or consummation of the Transaction. Expectations regarding business outlook, including changes in revenue, pricing, capital expenditures, cash flow generation, strategies for the combined company's operations, gold and silver market conditions, legal, economic and regulatory conditions, and environmental matters are only forecasts regarding these matters.
