G2 Announces New Gold Discoveries Outside Existing Mineral Resources and Provides Corporate Update

• 100,000-metre drilling program underway, targeted for completion by year-end
  
• Drilling and trenching immediately north of the high-grade OMZ resource delivers significant oxide intercepts, including: 66m @ 0.9 g/t Au (OKND 30) and 6m @ 4.1 g/t Au (trench ONCH 3)
  
• New discovery at the "Sands" target area delivers near-surface, oxidized drill intercepts, including: 24m @ 2.5 g/t Au (NWOD 70), 5m @ 4.8 g/t Au (NWOD 69), and 21.4 m @ 0.5 g/t Au (NWOD 75)
  

G2 Goldfields Inc. ("G2" or the "Company") (TSX: GTWO; OTCQX: GUYGF) is pleased to provide an update on the Company's high-grade OKO Gold Project ("Oko" or the "Project"), Guyana, including a 100,000-meter drilling campaign and new gold discoveries located outside existing mineral resources.

The Company recently published a Preliminary Economic Assessment for the OKO Project, which outlined the potential for the construction and development of a 10,000 tonne-per-day gold mining operation with total production of 3.2 million ounces of gold at all-in sustaining costs¹ of US$1,232 per ounce over a 14-year mine life (see report titled "NI 43-101 Technical Report for the Preliminary Economic Assessment (PEA) on the Oko Gold Project in the Co-operative Republic of Guyana, South America", available on SEDAR+).

G2 continues to actively expand the Project through; (i) drilling extensions to known gold mineralisation along the +15km OKO trend, and (ii) drilling new greenfields discoveries along the rapidly developing 20km Aremu gold trend, where the Company has made several new gold discoveries (refer to Figure 1).

Corporate Update

During 2026, the Company's exploration campaigns will run in parallel with early works programs, as well as ongoing environmental and geotechnical studies, to further define and de-risk the mining operation, with the objective of completing a Feasibility Study and formal construction decision by mid-2027.

At present, G2 has two drilling contractors on site with six fully operational drill rigs. Two additional drill rigs are expected to be added next month to expedite the ongoing programs. Currently, four rigs are committed to resource expansion and exploration, and two rigs are devoted to upgrading and converting Inferred mineral resources to Indicated mineral resources for inclusion in the forthcoming Feasibility Study. The current 100,000-meter drill program supporting these deliverables is expected to be completed by year-end.

Exploration Update

G2 Goldfields continues to see considerable exploration success, further establishing the Oko Project both as a top-tier existing gold resource and a world-class gold exploration camp with significant upside potential. Ongoing drilling has confirmed the continuation of meaningful gold mineralization down-plunge of existing resources (see press release dated January 6, 2026), while greenfields exploration programs continue to generate new discovery success. At Oko North, diamond drill hole OKND 30 intercepted 66m @ 0.9 g/t Au from 25.5 meters downhole. In addition, discrete higher-grade intercepts at surface have been identified, including 6m @ 4.1 g/t Au from trench ONCH 3 in an exposed quartz vein system at surface (see Figure 2).

Additionally, G2 exploration teams conducted a modest reconnaissance drilling program in late 2025 in the Sands exploration area, located 4km northwest of the main Oko gold resource (see Figure 3). The Sands area, which is part of a broader 20km Aremu trend, has been the subject of widespread gold mining. This initial 1,513-meter drill program was successful in the discovery of a new, near surface gold discovery at the Oko Project, with shared geological characteristics with the high-grade OMZ deposit. Significant intercepts from the 11-hole program are outlined in Table 1 and are associated with the sheared contact between the strongly bleached volcanic rocks and carbonaceous mudstones, as is the case at the OMZ resource. The initial drilling targeted an interpreted shear zone and was successful in establishing a 200-meter strike length of intense shearing. This zone hosts laminated, textured quartz reefs containing fine visible gold grains, as recorded in the high-grade intercepts from holes NWOD 69 and NWOD 70. Encouragingly, multiple gold-in-soil anomalies exceeding 500 ppb Au have been identified up to 350 meters along strike to the east of the discovery area. Complete results for the Sands reconnaissance program are available here.

Notes to Table 1: Insufficient drilling has been completed to determine true widths at the sands target area.

Another area within the Aremu trend that will be a focus of drilling in the first quarter is the Oko NW area (Figure 4), which currently hosts a modest oxide resource. Reinterpretation of possible geological controls has resulted in a new drill program focused on the central portion of the district, where previous drilling and trenching identified significant potential for further follow-up. Notably, trench OKTR 5 returned 95.2m @ 1.1 g/t Au including 8m @ 9.3 g/t Au, and drill hole NWOD 22, located approximately 200 meters southeast of OKTR 5, intercepted 15m @ 6.3 g/t Au. Both intercepts occurred within highly oxidized material.

Dan Noone, G2 CEO, stated "As we continue to advance the OKO Project towards production, our focus remains on aggressive drilling to further grow and upgrade the Project's gold resource base. Recent results and discovery success continue to demonstrate the remarkable exploration potential and significant remaining upside across the Oko District."

"AISC" are calculated inclusive of open pit and underground mining costs; treatment, transport and refining costs; processing and surface costs; G&A, royalties and other costs, sustaining capital expenses to support the on-going operations, and closure/reclamation costs. This metric is calculated on a payable gold ounce basis.

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 mineralisation 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.
