G2 Goldfields Inc Extends High-Grade Oko Resource To Depths Of 1km And Reports Drilling Results
G2 Goldfields Inc. reported new assay results from its ongoing diamond drilling program at the Company’s OKO Project in Guyana. The latest drilling successfully extended high-grade shoots down-plunge at the Ghanie deposit, upgraded and confirmed central infill mineralization, and extended gold mineralization south of the existing Ghanie resource along the “Border Zone”. Deepest hole drilled to date by G2 returned 84.5m @ 3.0 g/t Au from 915m, extending mineralization by 140m vertically to 1km, where it remains open. Eight drill rigs actively focused on infill, expansion and discovery drilling, with infill holes returning high-grade intercepts, including GDD270 which returned 20.8m @ 9.6 g/t Au incl. 4.4m @ 36.1 g/t Au. Drilling in the “Border Zone” continues to extend gold mineralization south of the existing Ghanie resource, with a high-grade interval of 3.0m @ 10.8 g/t Au from 490m, building on strong prior results in this area. Assay results are reported herein for 22 new diamond drill holes completed within the Ghanie deposit, totalling 10,828 metres. New hole GDD277B returned 84.5m @ 3.0 g/t Au, including 6.0m @ 13.4 g/t Au and 16.4m @ 4.5 g/t Au, representing the deepest intercept at the Oko Project to date and extending mineralization by an additional 140m vertically to 1km where it remains open. In addition, GGD271A intercepted 1.5m @ 8.1 g/t Au, 3.0m @ 6.1 g/t Au and 3.0m @ 5.8 g/t Au and ended in mineralization at 954m. These intercepts occur within the principal Ghanie shear zone along the contact between Ghanie diorite and magnetite diorite host rocks, consistent with the Company’s geological model. These results demonstrate economic widths and grades well beyond the limits of the current mineral resource and highlight the continued growth potential of the Ghanie gold system. New infill holes successfully confirmed the high-grade nature of the central Ghanie deposit, returning 6.0m @ 11.0 g/t Au (incl. 1.5m @ 40.9 g/t Au) from 104m (GDD279), 20.8m @ 9.6 g/t Au (incl. 2.0m @ 8.5g/t Au, 1.0m @ 14.2g/t Au and 4.4m @ 36.1 g/t Au) from 298m (GDD270), 7.2m @ 7.8 g/t Au (incl. 3.0m @ 18.2g/t Au) from 333m (GDD273), and 2.8m @ 23.2 g/t Au from 437m (GDD276). Hole GDD265W1 targeted the “Border Zone” located south of the Ghanie open pit shell, as defined in the PEA, and toward G Mining’s Oko West deposit. GDD265W1 extended mineralization beyond the current resource an additional 50m and returned a high-grade interval of 3.0m @ 10.8 g/t Au, supporting the potential for future open pit resource expansion. This drilling builds on prior drilling in this area that intercepted strong near-surface gold mineralization, including 2.7m @ 39.3g/t Au from 186m (GDD258), 30.0m @ 2.1g/t Au from 59m (GDD247), and 19.5m @ 2.3g/t Au (incl. 3.0m @ 12.5g/t Au) from 223m (GDD251A). The mineral resource was prepared by Micon International Limited with an effective date of November 20, 2025. The Oko district has been a prolific alluvial goldfield since its initial discovery in the 1870s, and modern exploration techniques continue to reveal the considerable potential of the district. Drill core is logged and sampled in a secure core storage facility located on the Project site, Guyana. Core samples from the program are cut in half, using a diamond cutting saw, and are sent to MSALABS Guyana, in Georgetown, Guyana, which is an accredited mineral analysis laboratory, for analysis. Samples from sections of core with obvious gold mineralization are analysed for total gold using an industry-standard 500g metallic screen fire assay (MSALABS method MSC 550). All other samples are analysed for gold using standard Fire Assay-AA with atomic absorption finish (MSALABS method; FAS-121). Samples returning over 10.0 g/t gold are analysed utilizing standard fire assay gravimetric methods (MSALABS method; FAS-425). Certified gold reference standards, blanks, and field duplicates are routinely inserted into the sample stream, as part of G2 Goldfield’s QA/QC program. No QA/QC issues were noted with the results reported herein.
