G Mining Ventures Announces Receipt of Final Environmental Permit
for Oko West Gold Project in Guyana
BROSSARD, QC, September 2, 2025 – G Mining Ventures Corp. (“GMIN” or the “Corporation”) (TSX: GMIN,
OTCQX: GMINF) is pleased to announce it has received the Environmental Permit (the “EP”) from Guyana’s
Environmental Protection Agency (“EPA”) for the Oko West Gold Project (“Oko West” or the “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, multi -stakeholder 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 & 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 ec onomic benefits. With this approval, a favorable 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 ongoing 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 Commi ssion (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 H2 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.
