Mr. Louis-Pierre Gignac of G Mining reports

G MINING VENTURES AND G2 GOLDFIELDS ANNOUNCE CLOSING OF ARRANGEMENT

G Mining Ventures Corp. and G2 Goldfields Inc. have successfully completed the plan of arrangement under the Canada Business Corporations Act, pursuant to which G Mining has acquired all of the issued and outstanding common shares of G2 and G2 has completed a spinout transaction with G3 Goldfields Inc.

Pursuant to the arrangement, each G2 share was exchanged for 0.212 of a common share of G Mining and 0.50 of a common share of G3.

Louis-Pierre Gignac, chief executive officer, president and a director of G Mining, stated: "The acquisition of G2 further strengthens our position as we continue to build GMIN into a leading multiasset intermediate gold producer in the Americas. By bringing together two adjacent deposits that form part of the same mineralized system under a single operation, we have created a large-scale, low-cost, fully permitted and fully financed Tier 1 gold mining complex in one of the world's most prospective gold districts. The combination is expected to generate substantial near- and long-term value for our shareholders through significant operational and capital synergies, including shared infrastructure, optimized mine planning, enhanced operational flexibility and increased processing capacity."

As a result of the completion of the arrangement, it is expected that the G2 shares will be delisted from the Toronto Stock Exchange and withdrawn from quotation on the OTCQX Best Market of the OTC Markets Group and that G2 will cease to be a reporting issuer (or equivalent) under applicable Canadian securities laws. G3 has applied to list its common shares for trading on the Canadian Securities Exchange, with listing subject to G3 meeting the listing requirements of the CSE.

Further details regarding the arrangement are included in G2's management information circular dated May 12, 2026, a copy of which is available under G2's issuer profile on SEDAR+. Former G2 shareholders are reminded to review the circular in respect of the procedure for receiving their consideration. Registered shareholders (whose G2 shares were held in physical form or who had a direct registration system (DRS) advice) must complete, sign and return the letter of transmittal, along with their share certificate(s) or DRS advice(s), to TSX Trust Company, the depositary for the arrangement. Non-registered shareholders (whose G2 shares were held with a broker, bank or other intermediary) should contact their intermediaries for instructions and assistance in receiving their consideration, which is expected to be distributed to the applicable intermediaries through CDS Clearing and Depository Services Inc. within the next three business days.

Disclosure of historical estimates of G2 mineral resources

G Mining wishes to clarify that all references to the mineral resources of the Oko-Ghanie project included in the joint press release issued by G Mining and G2 on April 9, 2026, initially announcing the arrangement do not represent, from G Mining's perspective, a current mineral resource estimate of the Oko-Ghanie project. Rather, such information was provided by G Mining as a historical estimate within the meaning of National Instrument 43-101, Standards of Disclosure for Mineral Projects.

G Mining's qualified person has not done sufficient work to classify the historical mineral resources estimates of the Oko-Ghanie project referenced therein as current mineral resources and, consequently, G Mining is not treating such historical estimates as current mineral resources. Verification of the historical mineral resources estimates of the Oko-Ghanie project is required in order to upgrade them to current mineral resources, which will involve conducting the following work: (i) combination of all data relating to the Oko-Ghanie project and G Mining's Oko West project; (ii) geological modelling of the combined projects; and (iii) additional drilling.

Upon such additional work being completed, a press release will be issued to reflect the results for the combined mineral resources of the Oko-Ghanie project and the Oko West project, and a technical report will be issued within 45 days thereof in accordance with NI 43-101. Additional technical studies will thereafter continue to verify the optimal mine plan, sequencing and throughput for the combined projects, with an intention to release a technical report in 2027.

The historical mineral estimates of the Oko-Ghanie project are supported by an NI 43-101 technical report titled "NI 43-101 Technical Report for the Preliminary Economic Assessment (PEA) on the Oko Gold Project in the Co-operative Republic of Guyana, South America," with an effective date of Dec. 8, 2025.
