G Mining Ventures Reports New High-Grade Discovery at Oko West and Extension of Mineralization at Gurupi

Executive Summary

• G Mining Ventures reported significant high-grade gold intercepts at its Oko West Project in Guyana, including the discovery of a second high-grade plunge beyond current pit limits and validation of a new "Splay Model" for structural exploration.
• At the Gurupi Project in Brazil, trenching results confirmed the extension of mineralization 2 km north of the Chega Tudo deposit at the Grodiocal target, validating the prospectivity of the land package ahead of a planned drilling program.
• The company approved an expanded 2025 exploration budget of USD $6–8 million for Gurupi, with plans to complete 7,500 meters of RC drilling by year-end and initiate diamond drilling for the Cipoiero extension once permits are secured in Q1 2026.

  • Hole OKWD25-533: 14.0 m at 4.38 g/t Au and 15.5 m at 3.53 g/t Au
• Oko West Splay Model Validation:
  • Hole OKWD25-545: 11.9 m at 5.26 g/t Au
  • Hole OKWD25-516: 14.0 m at 1.10 g/t Au
  • Additional Splay intercepts include 7.0 m at 2.08 g/t Au (OKWD25-545), 5.0 m at 2.22 g/t Au (OKWR25-1838), 6.1 m at 1.73 g/t Au (OKWD25-528), and 10.8 m at 0.90 g/t Au (OKWD25-517).
• Gurupi Trenching Results (Grodiocal Target):
  • Trench GMAMT-25-008: 9.0 m at 3.52 g/t Au
  • Trench GMAMT-25-005: 3.0 m at 3.63 g/t Au and 7.0 m at 0.97 g/t Au
  • Trench GMAMT-25-001: 3.0 m at 2.09 g/t Au and 5.0 m at 0.89 g/t Au
• Gurupi Exploration Program & Budget:
  • Expanded 2025 budget approved at USD $6–8 million (up from USD $2–4 million).
  • Planned 10,000 m of RC drilling, with 7,500 m expected to be completed by year-end 2025.
  • Planned 8,500 m of Diamond Drilling (DD) for the Cipoiero extension, commencing after permit receipt in Q1 2026.
  • Regional soil sampling and trenching planned to generate new targets.
• Regional Exploration (Oko West):
  • NW extension target located 10 km northwest of Oko West shows strong soil anomalies.
  • Planned 6,300 m of trenching and RC drilling, potentially followed by diamond drilling.
• Gurupi Resource Context:
  • Current resources include 1.83 Moz indicated (43.5 Mt at 1.31 g/t Au) and 0.77 Moz inferred (18.5 Mt at 1.29 g/t Au).
  • Project covers ~1,900 km² across 47 contiguous tenements along the Tentugal shear zone.

Notable Quotes

• "Exploration at Oko West continues to expand our understanding of the deposit and reinforces the robust economics demonstrated in the Feasibility Study, while at Gurupi, trenching results validate near-surface mineralization, demonstrating the high prospectivity of the large land package" — Julie-Anaïs Debreil, Vice President Geology & Resources.
• "High-grade intercepts confirm Oko West's exceptional potential and support future mine life extensions. At Gurupi recent work provide the confidence to launch our first drill program later this year. Combined with Tocantinzinho's robust cash flow, our pipeline of high-quality projects firmly positions GMIN to become the next intermediate gold producer." — Julie-Anaïs Debreil, Vice President Geology & Resources.
