G2 Goldfields Inc. (TSE: GTWO) (OTCMKTS: GUYGF) updated its mineral resource estimate for its 83,967 acre Oko Project in Guyana, using data from the 188 new drill holes and 59,156 new meters.
Announced on Monday, the new mineral resource estimate includes a total indicated resources of 1.5 Moz at a grade of 3.40 grams per ton gold (g/t Au) and included high-grade, near surface zones at the Oko Main Zone (OMZ) of 609,000 ounces with an average grade of 10.25 g/t Au within 5 to 370 meters from the surface.
Furthermore, the inferred resources total 1.6 Moz at 2.48 g/t Au and include high-grade, near-surface zones at OMZ, which contain 360,000 oz at an average grade of 7.28 g/t Au within approximately 5 to 560 metres from the surface.
Micon International Limited (Micon) prepared the estimate in accordance with National Instrument 43-10, with an effective date of March 1, 2025.
A prominent 2.5 km long north-south structure hosts the bulk of the gold mineralization, with the high-grade OMZ to the north and the bulk mineable, disseminated Ghanie Gold Zone (Ghanie) to the south. The new Resource incorporates all drilling data collected up to the end of January 2025, marking a significant increase from the previous estimate released on April 3, 2024.
The OMZ and Ghanie deposits contain multiple plunging zones of high-grade mineralization that remain open at depth. The ongoing drill program continues to target these zones successfully at Ghanie North and the OMZ Shear 3, where multiple recent drill holes have intersected visible gold. Two diamond drill rigs are currently active, focusing on high-grade plunging mineralization.

Drilling has consistently found gold-bearing structures
The G2 team remains focused on near-surface targets in the greater Oko area, including assets for the G3 Goldfields Inc. (G3) spin-out.
The team considers the potential for discovering additional gold resources to be excellent. G2 is drilling several prominent gold-in-soil anomalies north of the Oko Project. Additionally, experts interpret this as part of a regional structural break. The company is also conducting a major soil sampling and mapping program across its greater property portfolio.
Drilling has consistently intersected significant gold-bearing structures. For example, the OMZ features high-grade, near-surface mineralization and the Ghanie Gold Zone presenting a bulk mineable, disseminated resource. The project’s geological setting lies within a major regional structural corridor, which continues to yield new targets through ongoing exploration.
G2 Goldfields has deployed multiple diamond drill rigs to expand known mineralized zones and test high-priority anomalies. The company is also conducting extensive soil sampling, mapping, and geophysical surveys to refine its exploration strategy.
