TORONTO, March 27, 2024 (GLOBE NEWSWIRE) -- Alamos Gold Inc. ("Alamos") (TSX:AGI, NYSE:AGI) and Argonaut Gold Inc. ("Argonaut") (TSX:AR) are pleased to announce that they have entered into a definitive agreement (the "Agreement") whereby Alamos will acquire all of the issued and outstanding shares of Argonaut pursuant to a court approved plan of arrangement (the "Transaction").

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 US$515 million¹. The addition of Magino is expected to increase Alamos' 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' 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 shares and 1 share of SpinCo² (the "Exchange Ratio"). The Exchange Ratio implies estimated total consideration of C$0.40 per Argonaut common share, or US$325 million. This represents a 34% premium based on Argonaut's and Alamos' closing prices on March 26, 2024 on the Toronto Stock Exchange ("TSX"), and a 41% premium based on both companies' 20-day volume-weighted average prices. Total consideration includes C$0.34 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 C$0.06³. Alamos expects to issue approximately 20.3 million common shares as part of the Transaction, representing an equity value of approximately US$276 million on a fully diluted in-the-money basis, and an enterprise value of US$516 million.

Upon completion of the Transaction, existing Alamos and Argonaut shareholders will own approximately 95% and 5% 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 2024⁴, and increase to over 400,000 ounces per year at first quartile costs, following the completion of the Phase 3+ 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 years⁵, with significant exploration upside

Immediate value creation – the combination of Island Gold and Magino is expected to unlock pre-tax synergies of approximately US$515 million¹ over the life of mine. This includes operating synergies of US$375 million, through the use of the larger centralized mill and tailings facility at Magino, and capital savings of US$140 million 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% to over 600,000 ounces per year⁴, 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% of the combined Company's net asset value⁶ supported by its Canadian assets, solidifying Alamos' position as the 3^rd 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+ 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 CEO 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.

Alamos Cautionary Note to U.S. Investors

All references to Resource and Reserve estimates included in this News Release are made in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Standards"). NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Mining disclosure in the United States was previously required to comply with SEC Industry Guide 7 ("SEC Industry Guide 7") under the United States Securities Exchange Act of 1934, as amended. The U.S. Securities and Exchange Commission (the "SEC") has adopted final rules, to replace SEC Industry Guide 7 with new mining disclosure rules under sub-part 1300 of Regulation S-K of the U.S. Securities Act ("Regulation S-K 1300") which became mandatory for U.S. reporting companies beginning with the first fiscal year commencing on or after January 1, 2021. Under Regulation S-K 1300, the SEC now recognizes estimates of "Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral Resources". In addition, the SEC has amended its definitions of "Proven Mineral Reserves" and "Probable Mineral Reserves" to be substantially similar to international standards.

Investors are cautioned that while the above terms are "substantially similar" to CIM Definitions, there are differences in the definitions under Regulation S-K 1300 and the CIM Standards. Accordingly, there is no assurance any Mineral Reserves or Mineral Resources that may be reported as "Proven Mineral Reserves", "Probable Mineral Reserves", "Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral Resources" under NI 43-101 would be the same had the Mineral Reserve or Mineral Resource estimates been prepared under the standards adopted under Regulation S-K 1300. U.S. investors are also cautioned that while the SEC recognizes "Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral Resources" under Regulation S-K 1300, investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of Mineral Resources or into Mineral Reserves. Mineralization described using these terms has a greater degree of uncertainty as to its existence and feasibility than mineralization that has been characterized as Reserves. Accordingly, investors are cautioned not to assume that any Measured Mineral Resources, Indicated Mineral Resources, or Inferred Mineral Resources that are reported are or will be economically or legally mineable.

Argonaut Cautionary Statement

Certain information contained or incorporated by reference in this press release, including any information as to our strategy, projects or future financial or operating performance, constitutes "forward-looking statements". Forward-looking statements are frequently characterized by words such as "estimate", "plan", "anticipate", "expect", "intend", "believe(s)", "potential", or statements that certain events or conditions "may", "should" or "will" occur, and similar expressions. This press release contains forward-looking statements and forward-looking information including, but not limited to: the timing and ability to refinance the existing term loan, the results of independent engineer technical reviews, the estimation of the Mineral Reserves and Resources, the realization of Mineral Reserve and Resource estimates, expected capital expenditures, costs and timing of development of new deposits, success of exploration activities and permitting requirements.

Forward-looking statements are based on a number of assumptions, opinions and estimates, including estimates and assumptions in regards to the factors listed below that, while considered reasonable by the Company as at the date of this press release based on management's experience and assessment of current conditions and anticipated developments, are inherently subject to significant business, economic and competitive uncertainties and contingencies. Many of these assumptions are based on factors and events that are not within the control of Argonaut and there is no assurance they will prove to be correct. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking statements and undue reliance should not be placed on such statements and information. Such factors include, but are not limited to: the Company's ability to continue as a going concern, satisfying the conditions precedent for further draws on the Loan Facilities, satisfying ongoing covenants under the Loan Facilities, results of independent engineer technical reviews, the availability and change in terms of financing, the possibility of cost overruns and unanticipated costs and expenses, the ability of the Magino mine to be one of the largest and lowest cost gold mines, the winding down of the Mexican mines, the impact of inflation on costs of exploration, development and production, risk of employee and/or contractor strike actions, the future price of gold and silver, the estimation of the Mineral Reserves and Resources, the realization of Mineral Reserve and Resource estimates, the timing and amount of estimated future production at the Magino mine, Florida Canyon mine, La Colorada mine, San Agustin mine and El Castillo mine, mine closure plans for the La Colorada mine and El Castillo mine, costs of production (including cash cost per gold ounce sold), expected capital expenditures, costs and timing of development of new deposits, success of exploration activities, permitting requirements, currency fluctuations, the ability to take advantage of forward sales agreements profitably, the ability to recover property potentially impaired by third party insolvency proceedings, requirements for additional capital, government regulation of mining operations, environmental risks and hazards, title disputes or claims, limitations on insurance coverage, the use of proceeds from financings, the potential sale of the Company's non-core Mexican assets, and the timing and ability to refinance the existing Term Loan.

These factors are discussed in greater detail in the Argonaut's most recent Annual Information Form dated March 31, 2023, and in the most recent Management's Discussion and Analysis for the three and twelve months ended December 31, 2023, both filed under the Company's issuer profile on SEDAR+. Argonaut cautions that the foregoing list of important factors is not exhaustive. Investors and others who base themselves on forward-looking statements should carefully consider the above factors as well as the uncertainties they represent and the risk they entail.

Forward-looking statements included in this press release speak only as of the date of this press release. Although Argonaut has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Argonaut undertakes no obligation to update forward-looking statements if circumstances or management's estimates or opinions should change except as required by applicable securities laws.
