ALAMOS GOLD ANNOUNCES FRIENDLY ACQUISITION OF ARGONAUT GOLD

Alamos Gold Inc. and Argonaut Gold Inc. have entered into a definitive agreement whereby Alamos will acquire all of the issued and outstanding shares of Argonaut pursuant to a court-approved plan of arrangement.

As part of the transaction, Alamos will acquire Argonaut's Magino mine, located adjacent to its Island Gold mine in Ontario, Canada. The integration of the two operations is expected to create one of the largest and lowest cost gold mines in Canada. Through the use of shared infrastructure, Alamos expects to unlock significant value with immediate and long-term synergies expected to total approximately $515-million (U.S.). The addition of Magino is expected to increase Alamos's combined gold production to over 600,000 ounces per year, with longer-term production potential of over 900,000 ounces per year. The combination materially enhances Alamos's position as a leading, Canadian-focused, intermediate producer, with growing production and declining costs.

Concurrently with the transaction, Argonaut's assets in the United States and Mexico will be spun out to its existing shareholders as a newly created junior gold producer (SpinCo). SpinCo will own the Florida Canyon mine in the United States, as well as the El Castillo complex, the La Colorada operation and the Cerro del Gallo project, located in Mexico.

Under the terms of the agreement, each Argonaut common share outstanding will be exchanged for 0.0185 Alamos common share and one share of SpinCo (the exchange ratio). The exchange ratio implies estimated total consideration of 40 cents per Argonaut common share, or $325-million (U.S.). This represents a 34-per-cent premium based on Argonaut's and Alamos's closing prices on March 26, 2024, on the Toronto Stock Exchange, and a 41-per-cent premium based on both companies' 20-day volume-weighted average prices. Total consideration includes 34 cents of Alamos common shares, based on the closing price of Alamos common shares on the TSX on March 26, 2024, and SpinCo common shares with an estimated value of 6.3 cents. Alamos expects to issue approximately 20.3 million common shares as part of the transaction, representing an equity value of approximately $276-million (U.S.) on a fully diluted in-the-money basis, and an enterprise value of $516-million (U.S.).

Upon completion of the transaction, existing Alamos and Argonaut shareholders will own approximately 95 per cent and 5 per cent of the pro forma company, respectively.

Transaction highlights:

• Creation of one of Canada's largest, lowest-cost and most-profitable gold mines -- combined Magino and Island gold mines are expected to produce approximately 280,000 ounces in 2024, and increase to over 400,000 ounces per year at first-quartile costs, following the completion of the phase 3-plus expansion in 2026. The two deposits contain mineral reserves of 4.1 million ounces, and total mineral reserves and resources of 11.5 million ounces, supporting a mine life of more than 19 years, with significant exploration upside.
• Immediate value creation -- the combination of Island gold and Magino is expected to unlock pretax synergies of approximately $515-million (U.S.) over the life of mine. This includes operating synergies of $375-million (U.S.), through the use of the larger centralized mill and tailings facility at Magino, and capital savings of $140-million (U.S.) with the mill and tailings expansions at Island gold no longer required.
• Enhances position as a leading intermediate gold producer -- combined near-term gold production is expected to increase approximately 25 per cent to over 600,000 ounces per year, with longer-term growth potential to over 900,000 ounces per year, at declining costs.
• Leading Canadian exposure supporting a low political risk profile -- with 88 per cent of the combined company's net asset value supported by its Canadian assets, solidifying Alamos's position as the third-largest gold producer in Canada.
• Longer-term upside potential -- significant further upside potential at both Magino and Island gold through an expansion of a single optimized milling complex at Magino.
• Stronger financial capacity -- to complete the ramp-up and optimization of the Magino mine, unlocking the full potential of the operation. Stronger overall cash-flow generation to support portfolio of organic growth projects, including the phase 3-plus expansion at Island gold and Lynn Lake.

"This is a logical and attractive transaction for both companies. The combination of the adjacent Island gold and Magino mines will immediately unlock tremendous value, with significant longer-term upside through further optimizations of the combined operation, and ongoing exploration success. Both assets complement each other well, with large mineral reserve and resource bases, long mine lives, and existing infrastructure that can support the bright future for the larger combined operation. Together, Island gold and Magino will create one of the largest and most-profitable mines in Canada, further enhancing our leading position as a Canadian-focused intermediate gold producer," stated John A. McCluskey, president and chief executive officer of Alamos Gold.

"After considering a broad range of alternatives, we believe this transaction provides a unique opportunity to place Magino in the hands of a well-capitalized and well-run company, who will be able to realize significant synergies given the proximity of the adjacent Island gold mine. We believe with adequate capital and an optimal expansion at Magino, the mine will deliver significant value to all stakeholders. We are grateful to our team at Magino for their significant contribution and hard work during mine and mill ramp-up. Similarly, we thank our exceptional teams in Mexico and Nevada for their continued hard work throughout the years," stated Richard Young, president and CEO of Argonaut Gold.

Benefits to Alamos shareholders:

• Operating and capital synergies of $515-million (U.S.) through the integration of Island gold and Magino;
• Larger, established mill and tailings infrastructure at Magino to accommodate the rapidly growing mineral reserve and resource base at Island gold;

• Further production upside potential through the optimization and expansion of the Magino-Island gold complex;
• Strengthens core portfolio with addition of a fourth core, long-life, producing mine with a large mineral reserve and resource base, and exploration upside;

• Expands upon leading exposure to Canada with 88 per cent of net asset value supported by Canadian assets;
• Stronger operating cash flow to support organic growth projects, including the phase 3-plus expansion at Island gold and the Lynn Lake project.

Benefits to Argonaut shareholders:

• Significant premium of approximately 41 per cent based on the 20-day volume-weighted average prices of both companies;
• Continuing participation in the substantial synergies generated from the integration of Island gold and Magino;
• Exposure to Alamos's high-quality portfolio of assets, including diversified North American gold production and strong growth profile;

This will provide Alamos with a 14-per-cent interest in Argonaut on an issued and outstanding basis.
