G2 GOLDFIELDS DRILLING CONTINUES TO EXPAND HIGH-GRADE GOLD RESOURCE AT OKO

G2 Goldfields Inc. has released new assay results from the company's continuing diamond drill program at the Oko project in Guyana. In December, 2025, G2 released key findings from an independent preliminary economic assessment (PEA) (see press release dated Dec. 18, 2025). The PEA outlined a combined open-pit and underground operation with a 14-year mine life with total gold production estimated at 3.2 million ounces at all-in sustaining costs (AISC) of $1,191 (U.S.) per ounce. Gold production is estimated at 298,000 ounces per annum during years 3 through 10. The Oko gold project will contribute significantly to Guyana's economy through payments of royalties, taxes and employment opportunities. Assay results are reported hereunder for 16 new diamond drill holes totalling 5,997 metres. Highlights of the results are compiled in Table 1.

All of the drill holes, with the exception of hole GDD256A, targeted the Border zone area located south of the Ghanie open-pit shell, as defined in the PEA. The program successfully intercepted near-surface gold mineralization in hole GDD247, which returned 30.0 m at 2.1 grams per tonne gold from 58.5 m downhole, as well as deeper gold mineralization encountered in hole GDD260, which assayed 5.5 g/t Au over 5.0 m from 533 m downhole. Multiple gold intercepts occurred in several of the drill holes at more moderate depths, with hole GDD251A returning 10.5 m at 2.6 g/t Au, 19.5 m at 2.3 g/t Au and 22.3 m at 1.1 g/t Au. Exceptionally high-grade gold was intercepted in hole GDD258, which returned 39.3 g/t Au over 2.7 m.

Diamond drill hole GDD256A was designed to test for deeper downplunge mineralization from the more central part of the Ghanie resource area and was drilled to a final depth of 963 m. Between 862 m and 912 m downhole, a broad zone of gold mineralization assaying 2.4 g/t Au over 50.0 m was intercepted, including a higher-grade interval of 4.0 g/t Au over 23.5 m. This now represents the deepest intercept in the Ghanie deposit and the deepest drill hole on the Oko project to date. The intercept is within the principal Ghanie shear zone, which occurs on the hangingwall contact of the relatively rigid Ghanie diorite and less competent magnetite diorite host rocks, as predicted by the geological model. This intercept confirms the depth extension potential of the Ghanie gold system, demonstrating economic widths and grades well beyond the limits of the current mineral resource estimate.

Daniel Noone, chief executive officer of G2, stated: "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."

Quality assurance/quality control

Drill core is logged and sampled in a secure core storage facility located on the project site in 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 analyzed for total gold using an industry-standard 500-gram metallic screen fire assay (MSALabs method MSC 550). All other samples are analyzed for gold using standard fire assay AA with atomic absorption finish (MSALabs method FAS-121). Samples returning over 10.0 g/t gold are analyzed 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.

About G2 Goldfields Inc.

G2 Goldfields finds and develops gold deposits in Guyana. The founders and principals of the company have been directly responsible for the discovery of more than 11 million ounces of gold in the prolific and underexplored Guiana Shield. G2 continues this legacy of exploration excellence and success. Total combined open-pit and underground resources across all five discoveries to date include:

• 1,910,300 ounces gold -- inferred contained within 17.97 million tonnes at 3.31 g/t Au;
• 1,620,600 ounces gold -- indicated contained within 15,571,000 tonnes at 3.24 g/t Au.

The mineral resource was prepared by Micon International Ltd. with an effective date of Nov. 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.
