EURO MANGANESE ANNOUNCES SHARE CONSOLIDATION

As previously announced on March 6, 2025, and as approved by its board of directors, Euro Manganese Inc. will consolidate its issued and outstanding common shares at a ratio of five preconsolidation common shares to one postconsolidation common share. The consolidation will be effective as of March 31, 2025. The common shares will commence trading on a postconsolidation basis at the start of trading on April 2, 2025, on the TSX Venture Exchange, and the CDIs (as defined below) will commence trading on a postconsolidation basis at the start of trading on April 3, 2025, on the Australian Securities Exchange, all subject to necessary securities exchange approvals.

No fractional common shares or CDIs will be issued as a result of the consolidation. The holdings of any shareholder who would otherwise be entitled to receive a fractional common share or CDI as a result of the consolidation shall be rounded up to the next higher whole number if the fraction is 0.5 or greater, and rounded down to the next lower whole number if the fraction is less than 0.5.

Letters of transmittal are being mailed to all registered shareholders of the company with instructions on how to exchange existing share certificates for new share certificates or DRS statements.

Registered shareholders who hold their common shares through the direct registration system are not required to complete a letter of transmittal. A sample letter of transmittal is also available on the company's profile page on SEDAR+ if a registered shareholder does not receive a letter of transmittal in respect of its common shares represented by share certificates.

Non-registered shareholders (that is, beneficial shareholders) who hold their common shares or CDIs through an intermediary (that is, a securities dealer, bank or financial institution) should note that the intermediary may have different procedures for processing the consolidation from those that will be put in place by the company for registered shareholders. Shareholders who hold their common shares or CDIs through an intermediary who have questions in this regard should contact their intermediary for more information.

Prior to implementing the consolidation, the company had 402,669,227 common shares issued and outstanding (including 206,135,115 common shares represented by CHESS depositary interests listed on the ASX), and, immediately after implementing the consolidation, the company will have 80,533,845 common shares issued and outstanding (including 41,227,023 common shares represented by CDIs listed on the ASX), subject to final immaterial rounding, if any. As the consolidation applies equally to all holders of common shares or CDIs, individual shareholdings will be reduced in the same ratio as the total number of common shares or CDIs (subject to rounding). Accordingly, assuming no other market movements or impacts occur, the consolidation will have no effect on the percentage interest in the company of each holder of common shares or CDIs. In addition, the consolidation will not result in any change to the substantive rights and obligations of existing holders of common shares or CDIs.

The company's new Cusip number is 29872T209, and its new ISIN is CA29872T2092.

The company's outstanding options will be reorganized in accordance with their underlying terms and ASX listing Rule 7.22.1 (as applicable) on the same ratio as the consolidation with respect to the underlying common shares exercisable pursuant to the options, with adjustments being made to exercise or conversion prices, as applicable, in inverse proportion to that ratio.

For example, a holding of 100,000 options with an exercise price of 10 cents each prior to the consolidation would result in a holding of 20,000 options with an exercise price of 50 cents each after the consolidation.

In addition, the consolidation will not result in any change to the substantive rights and obligations of existing holders of options. The following table summarizes the number of common shares (including those represented by CDIs) and options of the company pre and postconsolidation.
