G Mining Ventures receives Oko W. environmental permit

Mr. Louis-Pierre Gignac reports G MINING VENTURES ANNOUNCES RECEIPT OF FINAL ENVIRONMENTAL PERMIT FOR OKO WEST GOLD PROJECT IN GUYANA G Mining Ventures Corp. has received the environmental permit (EP) from Guyana's Environmental Protection Agency (EPA) for the Oko West gold project. This key regulatory milestone follows the submission of GMIN's environmental and social impact assessment (ESIA) in November, 2024, and marks the culmination of a transparent, multistakeholder review process led by the EPA, which began with the establishment of terms of reference in early 2023 and was supported by nearly two years of baseline environmental and social studies. The five-year permit, valid through July, 2030, authorizes the construction and operation of Oko West, which is expected to create an average of 1,270 direct permanent jobs during its lifetime. "The receipt of the environmental permit is a pivotal milestone that de-risks Oko West and clears the path toward a construction decision later this year," commented Louis-Pierre Gignac, president and chief executive officer. "This achievement reflects constructive engagement with the EPA, the government of Guyana and the communities of Region 7 and demonstrates Oko West can progress responsibly safeguarding the environment, generating employment and delivering sustainable economic benefits. With this approval, a favourable gold price outlook and cash flow from TZ, GMIN is well positioned to advance the project in alignment with the highest environmental and social standards, creating lasting value for all stakeholders." A strong partnership with Guyana The receipt of the EP underscores the strong and continuing partnership between GMIN and the government of Guyana, whose transparent regulatory environment and timely decision-making are essential to achieving project milestones. Guyana continues to be recognized as an attractive destination for mining investment, as reflected in the Fraser Institute's recent Annual Survey of Mining Companies, 2024, which ranks the country as a top-10 mining jurisdiction globally, out of 82 jurisdictions evaluated. (i) In addition to the EPA, GMIN extends its appreciation to Guyana's other regulatory bodies including the Guyana Forestry Commission (GFC), the Guyana Revenue Authority (GRA), the Maritime Administration Department (MARAD), the Guyana Geology and Mines Commission (GGMC), the Ministry of Natural Resources, and all other agencies overseeing the mining sector, whose professionalism and collaborative spirit help advance the project responsibly and on schedule.

Early works and next steps GMIN began early works at Oko West in March, 2025, which included the development of a wharf on the Cuyuni River, access roads and construction of the permanent camp. Approximately $190-million has already been committed or negotiated for long-lead items such as mobile and marine equipment, grinding mills, the primary crusher and a power plant. Initial equipment deliveries are expected in the second half of 2025, enabling the corporation to begin self-performing earthworks on site. The corporation anticipates making a formal construction decision in H2 2025, at which time more details regarding project financing will be communicated. In the interim, detailed engineering and exploration activities continue at Oko West. About G Mining Ventures Corp.
