All statements, other than statements of historical fact, contained in this press release constitute "forward-looking information" and "forward-looking statements" within the meaning of certain securities laws and are based on expectations and projections as of the date of this press release. Forward-looking statements contained in this press release include, without limitation, those related to (i) the continued improvement across both mining and milling operations; (ii) the quoted comments of GMIN's President & Chief Executive Officer; and (iii) more generally, the section entitled "About G Mining Ventures Corp.".

Forward-looking statements are based on expectations, estimates and projections as of the time of this press release. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by the Corporation as of the time of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies. These estimates and assumptions may prove to be incorrect. Such assumptions include, without limitation, those relating to (i) the improved mine and plant productivity at TZ, (ii) the price of gold, and (iii) currency exchange rates; and those underlying the items listed in the above section entitled "About G Mining Ventures Corp."

Many of these uncertainties and contingencies can directly or indirectly affect, and could cause, actual results to differ materially from those expressed or implied in any forward-looking statements. There can be no assurance that, notably but without limitation, (i) the gold production, gold sales, plant throughput, gold recovery and average mining rate will improve or at least be maintained at same levels, or (ii) TZ and Oko West will grow GMIN into the next intermediate producer, as future events could differ materially from what is currently anticipated by the Corporation. In addition, there can be no assurance that Brazil and/or Guyana will remain mining friendly and prospective jurisdictions.

By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks exist that estimates, forecasts, projections and other forward-looking statements will not be achieved or that assumptions do not reflect future experience. Forward-looking statements are provided for the purpose of providing information about management's expectations and plans relating to the future. Readers are cautioned not to place undue reliance on these forward-looking statements as several important risk factors and future events could cause the actual outcomes to differ materially from the beliefs, plans, objectives, expectations, anticipations, estimates, assumptions and intentions expressed in such forward-looking statements. All of the forward-looking statements made in this press release are qualified by these cautionary statements and those made in the Corporation's other filings with the securities regulators of Canada including, but not limited to, the cautionary statements made in the relevant sections of the Corporation's (i) Annual Information Form dated March 27, 2025, for the financial year ended December 31, 2024, and (ii) Management Discussion & Analysis.
