Snapshot	CentroGold Project is a proposed open pit gold mining operation, comprising two deposits – Blanket and Contact. On December 20, 2024, G Mining Ventures Corp. announced the completion of its acquisition of tenements in the Gurupi Gold Belt, including the CentroGold Project, from BHP Group Limited’s subsidiaries In July 2019, Oz Minerals (acquired by BHP in 2023) released a pre-feasibility study for the Blanket and Contact deposits. G Mining Ventures (GMIN) views the project as an advanced-stage exploration asset, with over 135,000 meters of drilling completed. GMIN plans to redesign the project to align with current permitting and economics, and will update the gold resource shortly after the transaction closes to comply with NI 43-101 standards. The Project's size, scope, and development timeline will be redesigned to suit GMIN's long-term growth plans. GMIN intends to build on CentroGold's existing geologic model and redesign the Project.

Deposit type

• Vein / narrow vein
• Mesothermal

Summary:

Gold mineralisation within the CentroGold project is considered to be typical of mesothermal veinstyle, or orogenic-style gold mineralisation.

The host of the primary mineralisation at the CentroGold deposits is a coarse, equigranular intrusive of tonalitic composition, close to the contact with a fine-grained arenite. Rocks in the deposit have been significantly affected by hydrothermal alteration. Gold mineralisation is closely associated with sulphide content within zones of quartz-sericite-pyrite alteration.

Mineralisation at the Contact deposit is typically sub-vertical, with flatter lying high-grade zones hosted in rafts of sediment within the tonalite intrusion host rock. The Mineral Resource has been completed using two individual grade domains using a nominal 0.4 g/t gold cut-off grade for wireframing.

The Blanket deposit is a shallow dipping (approximately 20-30 degrees), tabular body of medium grade gold mineralisation. The Mineral Resource has been completed using five individual grade domains constructed using a nominal 0.5 g/t gold cut-off grade for wireframing.

Blanket Deposit
The reported Blanket Mineral Resource is contained within a volume defined by the following coordinates:
• 9,750,170 mN to 9,751,020 mN
• 364,240 mE to 364,820 mE
• 60 mRL to –180 mRL.

Mineralisation has a strike length of 850 metres, an across-strike length of 656 metres and runs from surface down to 240 metres below surface. Mineralisation is open at depth.

Contact Deposit
The reported Contact Mineral Resource is contained within a volume defined by the following coordinates:
• 9,749,325 mN to 9,750,620 mN
• 363,710 mE to 364,800 mE
• 60 mRL to –215 mRL.

Mineralisation has a strike length of 1,600 metres, an across strike width of approximately 300 metres, and runs from surface down to 275 metres below surface. Mineralisation is open at depth.
