Snapshot	The Gurupi Project (formerly CentroGold) is a district-scale gold project. The Project is an advanced-stage exploration asset. On December 20, 2024, G Mining Ventures Corp. completed of the acquisition of Gurupi Project. The results of the presented PFS are no longer relevant. A new mineral resource estimate (2025) are hosted across three deposits: Blanket, Contact (Cipoeiro area), and Chega Tudo. July 23, 2025 - The Court annulled the preliminary and installation licenses issued in 2011 to a prior operator and confirmed GMIN's ability to initiate a new environmental licensing process. On January 20, 2026, G Mining announced an exploration budget of approximately $21 million for Gurupi in 2026, focused on expanding mineral resources ahead of a Preliminary Economic Assessment expected to be released in the second half of 2026.

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.
