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 (i) the Project remaining on track and on budget for

commercial production in H2-2024; (ii) the Project commitments to track in line with the Feasibility Study; (iii) the power transmission line to be completed

in early H1-2024; (iv) the cyanide tailing storage facility to be completed in Q4-2023 and the flotation tailing storage facility to be completed in Q1-2024;

(v) the stockpiling of ore for commissioning activities to commence in Q4-2023; and

(vi) more generally,

the horizontal bar chart entitled "Project

Development Timeline" as well as the sections entitled "Timetable and Next Steps" and "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 the price of gold and currency exchange rates, those outlined in the Feasibility

Study and those underlying the items listed on 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, the Corporation will (i) continue to progress on

all fronts at the Project, to carry the self-perform approach with similar success as proven in the past and to continue taking care of the health and safety

of all its stakeholders (with no Lost Time Incidents), (ii) keep its expenditures and schedule in line with the Feasibility Study, (iii) carry its next steps as per

the above timetable and effect the transition to commercial production as contemplated, (iv) complete the transmission line in H1-2024 and bring the

Project into commercial production in the H2-2024, or at all, (v) advance TZ into one of the largest operating gold mines in

Brazil

, or (vi) use TZ to 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 (y) the Corporation's comprehensive regional exploration soil sampling program, its regional airborne campaign and its other

exploration activities will generate positive results and led to the addition of mineral resources; and (z) the

State of Pará, in

Brazil

, will remain a mining

friendly and prospective jurisdiction.

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 a number of 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

April 28, 2023

, for the financial year ended

December 31, 2022

, 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 time 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.
