Cautionary Statement on Forward-Looking Information

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 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 several 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 r elating to the price of gold and currency

exchange rates, those outlined in the Technical Report and those underlying the items listed i n 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 ma terially from those

expressed or implied in any forward-looking statements. There can be no assurance that, notably but without limitation, (i) GMIN will achieve

its objectives for Oko West, notably to bring the Project into commercial production, or (ii) GMIN will use TZ and Oko West to grow GMIN into

the next intermediate producer, or (iii) the exploration upside of GMIN’s properties will lead to additional mineral resources and reserves, as

future events could differ materially from what is currently anticipated by the Corporation. In addition, there can be no ass urance 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 no t 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 a number of important risk

factors and future events could cause the actual outcomes to differ materially from the beliefs, plans, objectives, expectati ons, 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. The Corporation cautions that

the foregoing list of factors that may affect future results is not exhaustive, and new, unforeseeable risks may arise from t ime to time. The

Corporation 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.
