I would like to thank the efforts of all of those who were involved including Jason Kosec who was instrumental in the completion of the transaction and we welcome as our incoming Chairman."

Stifel Canada acted as sole bookrunner for the Offering, which included a syndicate of underwriters consisting of BMO Capital Markets, Desjardins Capital Markets and National Bank Financial Inc. (collectively the "Underwriters").

Offering Highlights

Each Subscription Receipt will be automatically exchanged for, upon satisfaction or waiver of certain release conditions (including the satisfaction of all conditions precedent to the completion of the Acquisition) (the "Escrow Release Conditions"), without payment of additional consideration or further action on the part of the holder, one common share of the Company (each, a "Common Share") and one Common Share purchase warrant (each, a "Warrant"), with each Warrant exercisable to purchase one Common Share at a price of C$0.705 for a period of 36 months following the completion of the Offering.

The Acquisition is anticipated to close at the end of Q3 2025.

The gross proceeds from the sale of the Subscription Receipts, less 25% of the commission payable to the Underwriters in respect of the Subscription Receipts and certain expenses of the Underwriters, have been deposited and will be held in escrow by TSX Trust Company, as subscription receipt agent, and will be released upon the satisfaction or waiver of the Escrow Release Conditions.

The Company intends to use the net proceeds from the Offering to fund the upfront cash consideration for the recently announced acquisition of Equinox Gold Corp.'s Pan Mine, Gold Rock Project and Illipah Project as described in the August 7 Release.

All securities issued under the Offering will be subject to a hold period expiring four months and one day from the date hereof. The Offering is subject to final acceptance of the TSX Venture Exchange.

Caution Regarding Forward-Looking Information

This press release includes certain "forward-looking information" within the meaning of applicable Canadian securities legislation. All information herein, other than information of historical fact, constitutes forward-looking information. Forward-looking information is frequently, but not always, identified by words such as "expects", "anticipates", "believes", "intends", "estimates", "potential", "possible", and similar expressions, or statements that events, conditions, or results "will", "may", "could", or "should" occur or be achieved. This information is based on information currently available to Minera Alamos and Minera Alamos provides no assurance that actual results will meet management's expectations. Forward-looking information in this press release includes, but is not limited to: statements with respect to the proposed use of proceeds of the Offering; the timing and ability of the Company to satisfy the customary listing conditions of, and receive final acceptance of the Offering from, the TSX Venture Exchange (if at all); statements concerning future exploration plans at the Company's mineral projects; the Company's proposed business strategy; and the development and condition of the Company's mining assets; the completion of the Acquisition; the consideration payable under the Acquisition; the expected closing dates of the Acquisition; the timing and ability of the Company to complete the Acquisition and satisfy the Escrow Release Conditions (if at all); the timing and ability of the Company to obtain all necessary approvals in respect of the Acquisition; the appointment of Jason Kosec to the chairmanship of the Company; and future production, operations and growth and a result of the Acquisition.

The forward-looking information is based on assumptions and addresses future events and conditions that, by their very nature involve inherent risks and uncertainties. Actual results could differ materially from those currently anticipated in forward-looking information for many reasons. Minera Alamos' financial condition and prospects could differ materially from those currently anticipated in forward-looking information for many reasons such as: an inability to complete the Acquisition; an inability to receive requisite permits for mine operation, exploration or expansion; an inability to finance and/or complete updated resource and reserve estimates and technical reports which support the technical and economic viability of mineral production; changes in general economic conditions and conditions in the financial markets; changes in demand and prices for minerals; litigation, legislative, environmental and other judicial, regulatory, political and competitive developments; technological and operational difficulties encountered in connection with Minera Alamos' activities; and other matters discussed in this press release and in filings made with securities regulators. This list is not exhaustive of the factors that may affect any of Minera Alamos' forward- looking information. These and other factors should be considered carefully, and readers should not place undue reliance on Minera Alamos' forward-looking information. Minera Alamos does not undertake to update any forward-looking information that may be made from time to time by Minera Alamos or on its behalf, except in accordance with applicable securities laws.

The Company does not have a feasibility study of mineral reserves, demonstrating economic and technical viability for the Santana project, and, as a result, there may be an increased uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, including increased risks associated with developing a commercially mineable deposit. Historically, such projects have a much higher risk of economic and technical failure.

NEITHER TSX VENTURE EXCHANGE NOR ITS REGULATION SERVICES PROVIDER (AS THAT TERM IS DEFINED IN THE POLICIES OF THE TSX VENTURE EXCHANGE) ACCEPTS RESPONSIBILITY FOR THE ADEQUACY OR ACCURACY OF THIS RELEASE.
