Gurupi Project Mineral Resource Estimate
The Gurupi Project (formerly known as the CentroGold Project) comprises 47 contiguous tenements covering ~2,100 km2 situated along +80 km of known mineralized trend. The Project is located approximately 380 km southeast of Belém, capital of the State of Pará, and 500 km west northwest of São Luis, capital of the State of Maranhão.
The mineral resource estimate ("MRE") is contained within three deposits: Blanket and Contact (Cipoeiro area) and Chega Tudo. The MRE is based on 715 diamond drill holes, 220 reverse circulation holes, totaling 126,193m performed between 1995 and 2019. This MRE includes 32 infill drillholes that were not included in the database for the previous Pre-Feasibility Study completed by past operator, OZ Minerals. Although Blanket and Contact deposits are spatially close, only a few drillholes tested the continuity of the grade in between the two, representing an opportunity for growth of the mineral resources in the future.
Exploration efforts will focus on data compilation and interpretation, machine learning-based core relogging, conducting a high-resolution survey across 720 km², and completing soil sampling to follow up on historic gold showing and newly defined targets. These activities aim to assess and evaluate the land package's value. A budget of $2 to 4 million has been allocated for the project in 2025.

Tocantinzinho Gold Mine MRMR Update
TZ Gold Mines, inaugurated last year, has updated its Mineral Resources and Reserves following the integration of grade control data and infill diamond drillholes. The improved understanding of the deposit through these activities has led to a revision in resource estimates, successfully replacing reserves and reinforcing long-term operational planning. An additional 3,700 m of drilling validated the northwest extension of the TZ deposit in 2024, adding this 300 m extension in the presented Mineral Resources.
In 2024, a total of 73 koz were processed (1.7 Mt at 1.32 g/t Au) and 128 koz were stockpiled (4.8 Mt at 0.81 g/t Au) for a total of 201 koz (6.6 Mt at 0.95 g/t Au). Total remaining reserves at year end 2024 stand at 2.03 Moz (51.1 Mt at 1.24 g/t Au).
In 2025, near-mine exploration of $2 million is planned to test the extension at depth and on the northwest limb of the deposit. A regional exploration budget of $9 million is planned for 2025 to test 23 targets within a 5 km radius with the primary goal to identify additional deposits.

Oko West Project
The below MRE is effective as September 7, 2024, and formed the basis for the Preliminary Economic Assessment ("PEA") announced on September 9, 2024 (titled "Preliminary Economic Assessment NI 43-101 Technical Report – Oko West Gold Project", filed on Sedar+ under GMIN's profile). The exploration effort in 2024 since acquiring the project has been to convert inferred resources to indicated. The infill drilling since the PEA will support an updated resource estimate and inaugural mineral reserve estimate as part of the upcoming Feasibility Study on track for completion in Q2 2025. The long-term exploration strategy will continue to focus on exploration along strike to the south, at depth and in the northwest of the property.

Oko West Infill Drilling
A total of 49,000 m from 170 holes of drilling have been completed in 2024, of which 15,097 m from 55 holes since the merger with Reunion Gold on July 16th, 2024(Figure 6). This extensive drilling successfully achieved three purposes: (i) conversion of UG resources in Block 4, (ii) close spaced drilling to support statistical tests and interpolation parameters to be used in the estimation of the OP resources within Block 4, (iii) testing the continuity of the mineralization near surface and at depth in block 5 & 6. The results demonstrate the predictability of the PEA resource model and will support a good conversion rate of inferred material into indicated material. Highlights of intercepts include the following listed below.
The $8 million Oko West exploration program planned in 2025 will support the objective of expanding the mineral resource inventory to improve future mine plans and extend the mine's operational life. The program will focus on increasing resources within the pit footprint, exploring underground mineralization in Blocks 5 and 6, evaluating additional mineralized saprolite material, and identifying new deposits across the land package.

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 publication of a Feasibility Study for Oko West in Q2 2025, featuring the inaugural reserve estimate and updated mineral resources; (ii) the TZ mill being expected to operate at nameplate capacity; (iii) the restart of exploration activities at Gurupi and the opportunity for growing mineral resources in the future; (iv) the evaluation of the Gurupi land package's value, notably with soil sampling and newly defined exploration targets; (v) the reinforcement of long-term operational planning at TZ; (vi) the predictability of the PEA resource model for Oko West, which is expected to support a good conversion rate of inferred material into indicated material; (vii) the release of a NI 43-101 compliant mineral resource estimate for Gurupi; and (viii) more generally, the sections entitled "2025 Catalysts" 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 (notably the BRL/USD exchange rate), as well as the underlying assumptions enumerated in Appendix A of this press release (namely the open pit optimization parameters, the cut-off grade assumptions, the ore modelling and the expectations that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration) and 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) GMIN's 2024 operational success at TZ will be repeated in 2025, or (ii) TZ will generate sufficient free cash flow to advance the Oko West Project, or (iii) near-mine and/or regional exploration will yield positive results, or (iv) the Oko West Feasibility Study will prove positive and the final permits will be obtained, or (v) an official construction decision for Oko West will be made in 2025, or (vi) the Oko West exploration program will lead to expanding its mineral resource inventory (and also to improving future mine plans and extending the (eventual) mine's operational life), or (vii) gold mineral reserves will continue to replace ounces produced at TZ in the future, or (viii) regional exploration near TZ will identify additional deposits, or (ix) mineral resources will eventually demonstrate economic viability and be converted (in whole or in part) into mineral reserves, or * more generally, GMIN will achieve its stated objectives for TZ and Oko West or use TZ and Oko West to grow GMIN into the next mid-tier precious metals 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 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 (i) Annual Information Form of G Mining TZ Corp. (then known as G Mining Ventures Corp.) dated March 27, 2024, for the financial year ended December 31, 2023, (ii) Annual Information Form of G Mining Guyana Corp. (then known as Reunion Gold Corporation) dated April 25, 2024, for the financial year ended December 31, 2023, and (iii) 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.
