TORONTO, May 04, 2026 (GLOBE NEWSWIRE) -- G2 Goldfields Inc. (“G2” or the “Company”) (TSX: GTWO; OTCQX: GUYGF) is pleased to report new assay results from its ongoing diamond drilling program at the Company’s OKO Project in Guyana (“OKO” or the “Project”). 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”.

On April 9, 2026, G2 entered into a definitive agreement whereby neighbouring G Mining Ventures Corp. (“GMIN”) will acquire all of the issued and outstanding shares of G2 pursuant to a court approved plan of arrangement, expected to close in June 2026, subject to shareholder and court approvals. In December 2025, G2 released key findings from an independent Preliminary Economic Assessment (“PEA”) [see press release dated December 18, 2025] outlining a combined open pit and underground operation with a 14-year mine life and estimate total production of 3.2 million ounces gold at all-in sustaining costs¹ (“AISC”) of US$1,191 per ounce. Annual production is projected to average 298,000 ounces during years 3 through 10.

Assay results are reported herein for 22 new diamond drill holes completed within the Ghanie deposit, totalling 10,828 metres (“m”). Highlights of the results are compiled in Table 1, with a complete table of results available here.

High-Grade Extensions at Depth

Deep drilling continues to extend high-grade mineralization down plunge from the central portion of the Ghanie resource, following up on prior strong results from hole GDD256A, which returned 50.0m @ 2.4 g/t Au (incl. 23.5m @ 4.0g/t Au) from 862m (see press release dated January 6, 2026).

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.

Border Zone and Infill Drilling

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) [see press release dated January 6, 2026].

Daniel Noone, CEO of G2, stated, “These results continue to demonstrate the strong growth potential at the Oko Project, with mineralization remaining open both along strike and at depth. With eight drill rigs active, we remain focused on expanding and upgrading resources while advancing additional near-mine and district-scale targets across the greater Oko project area, which currently hosts 7 million ounces Indicated and 2.3 million ounces Inferred across two adjacent deposits. This round of drilling clearly suggests this tier 1 gold camp has significant room to grow.”

QA/QC

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.
