Cautionary Note Regarding Forward-Looking Information

This press release contains “forward-looking information” and “forward-looking statements” within the meaning of applicable securities laws (collectively, “forward-looking statements”). All statements other than statements of historical fact are forward-looking statements.

These statements include, but are not limited to, statements regarding the scheduled payment of interest on the Note, the Company’s ability to meet its obligations through the determined expiry date of the Note, the potential conversion of the Note into common equity, the Company’s future financial liquidity, cash flows, and operational performance.

Forward-looking statements are based on current estimates, assumptions, and beliefs of management. They involve known and unknown risks, uncertainties, and other factors that may cause actual results or events to differ materially from those expressed or implied.

Risk factors that could impact the Note and the interests payable under such Note include, among others, the Company’s ability to generate sufficient cashflow from operations to service the payment of the interest in cash or in common shares, the fluctuations in the market price of the Company’s common shares, which may prevent the conversion criteria from being met and force the debt to remain outstanding until maturity, and availability of sufficient cash reserves or refinancing options to repay the full principal and accrued interest, in cash or in common shares, upon the expiry date.

A further description of risks and uncertainties can be found in NMG’s Annual Information Form dated March 25, 2026, including in the section thereof captioned “Risk Factors”, which is available on SEDAR+ atwww.sedarplus.ca and on EDGAR atwww.sec.gov. Unpredictable or unknown factors not discussed in this Cautionary Note could also have material adverse effects on forward-looking statements.

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. Forward-looking statements are provided for the purpose of providing information about management’s expectations and plans relating to the future. The Company disclaims any intention or obligation to update or revise any forward-looking statements or to explain any material difference between subsequent actual events and such forward-looking statements, except to the extent required by applicable law.
