G2 Goldfields drills 50 m of 2.4 g/t Au at Oko

Executive Summary

• G2 Goldfields released assay results from 16 new diamond drill holes totaling 5,997 meters at the Oko project in Guyana, demonstrating continued expansion of high-grade gold resources.
• The drilling successfully identified near-surface mineralization, deeper high-grade intercepts, and a significant depth extension of the Ghanie deposit, confirming the system remains open in multiple directions.
• The results support the previously released Preliminary Economic Assessment (PEA) which outlined a 14-year mine life with estimated total production of 3.2 million ounces at an AISC of $1,191/oz.

Key Details

• Drilling Program Scope: 16 new diamond drill holes totaling 5,997 meters.
• Target Areas: Primarily the Border zone (south of the Ghanie open-pit shell) and deeper downplunge mineralization in the central Ghanie resource area.
• Significant Intercepts:
  • Hole GDD247: 30.0 m at 2.1 g/t Au from 58.5 m downhole (near-surface mineralization).
  • Hole GDD260: 5.5 g/t Au over 5.0 m from 533 m downhole (deeper mineralization).
  • Hole GDD251A:
    • 10.5 m at 2.6 g/t Au
    • 19.5 m at 2.3 g/t Au
    • 22.3 m at 1.1 g/t Au
  • Hole GDD258: 39.3 g/t Au over 2.7 m (exceptionally high-grade).
  • Hole GDD256A (Deepest Intercept):
    • 50.0 m at 2.4 g/t Au from 862 m to 912 m downhole.
    • Included higher-grade interval: 23.5 m at 4.0 g/t Au.
    • Represents the deepest intercept in the Ghanie deposit and the deepest drill hole on the Oko project to date (final depth 963 m).
• Geological Context: The deep intercept in GDD256A is within the principal Ghanie shear zone, confirming depth extension potential and economic widths/grades beyond current mineral resource estimate limits.
• Current Resource Estimates (as of Nov 20, 2025):
  • Inferred: 1,910,300 oz Au within 17.97 million tonnes at 3.31 g/t Au.
  • Indicated: 1,620,600 oz Au within 15,571,000 tonnes at 3.24 g/t Au.
• PEA Highlights (Dec 18, 2025):
  • Combined open-pit and underground operation.
  • 14-year mine life.
  • Total gold production: 3.2 million ounces.
  • All-in Sustaining Costs (AISC): $1,191/oz.
  • Production rate: 298,000 oz/annum during years 3 through 10.
• QA/QC: Samples analyzed at MSALabs Guyana using standard fire assay AA with atomic absorption finish, with metallic screen fire assay for high-grade sections and gravimetric methods for samples >10.0 g/t Au. No QA/QC issues noted.

Notable Quotes

• "These results continue to demonstrate the ongoing expansion of gold resources at the Oko project, with mineralization remaining open in multiple directions. With five rigs focused on the Ghanie/Border target areas, alongside continued greenfields exploration across the district, we are excited about the potential for additional gold discoveries in the greater Oko district. G2 will continue to unlock shareholder value by aggressively exploring and derisking its portfolio of gold projects." — Daniel Noone, Chief Executive Officer
