<div id="readability-page-1"><article>Toronto, Ontario--(Newsfile Corp. - December 30, 2025) - Minera Alamos Inc. (TSXV: MAI) (OTCQX: MAIFF) (&#34;Minera Alamos&#34; or the &#34;Company&#34;) is pleased to announce that the Company will consolidate its common shares at a ratio of ten pre-consolidation shares to one post-consolidation share (the &#34;Consolidation&#34;). The Company currently has 1,080,440,735 common shares issued and outstanding. Upon completion of the Consolidation, the Company will have approximately 108,044,073 common shares issued and outstanding. Some slight variance is expected due to fractional rounding. Fractional shares will be rounded down to the nearest whole number with no additional consideration. Shareholders approved the consolidation at its shareholder meeting held on July 16, 2025. All outstanding warrants and incentive stock options will be adjusted to increase their exercise price by a factor of ten and to reduce the number of common shares issued upon exercise by dividing by ten.The Consolidation is subject to final acceptance of the TSX Venture Exchange (the &#34;TSXV&#34;), and the Company expects to complete the Consolidation at the close of business on January 2, 2026, such that effective at the open of markets on January 5, 2026, the common shares of the Company will commence trading on a post-Consolidation basis.Holders of common shares of the Company who hold uncertificated shares (that is shares held in book-entry form and not represented by a physical share certificate), either as registered holders or beneficial owners, will have their existing book-entry account(s) electronically adjusted by the Company's transfer agent or, in the case of beneficial shareholders, by their brokerage firms, banks, trusts or other nominees that hold in street name for their benefit. Such holders generally do not need to take any additional actions to exchange their pre-consolidation shares for post-consolidation shares. If you hold your shares with such a bank, broker or other nominee, and if you have questions in this regard, you are encouraged to contact your nominee.Registered shareholders holding share certificates will be mailed a letter of transmittal advising of the Consolidation and instructing them to surrender the share certificates representing pre-Consolidation shares for replacement certificates or a direct registration advice representing their post-Consolidation shares. Until surrendered for exchange, each share certificate formerly representing pre-Consolidation shares will be deemed to represent the number of whole post-Consolidation shares to which the holder is entitled as a result of the Consolidation.Included in the number of outstanding shares set out above are 4,651,163 common shares that issued upon receipt of approval of the TSXV, to settle a contractual obligation as announced in the Company's news release dated December 9, 2025.About Minera AlamosMinera Alamos is a North American gold production and development Company.
