TORONTO, March 10, 2025 (GLOBE NEWSWIRE) -- G2 Goldfields Inc. (“G2” or the “Company”) (TSX: GTWO; OTCQX: GUYGF) is pleased to announce an updated Mineral Resource Estimate (“MRE” or “Resource”) within the Company’s 83,967-acre Oko Project, Guyana. The bulk of the gold mineralization lies along a prominent 2.5 km long north-south structure comprised of the high-grade Oko Main Zone (“OMZ”) to the north and a bulk mineable, disseminated resource to the south, known as the Ghanie Gold Zone (“Ghanie”). The new Resource includes all drilling data obtained up to the end of January 2025 and represents a significant increase to the previous estimate released on April 3, 2024.
Highlights
- Total Indicated gold resources increased by
60% to 1.5 million ounces (“Moz”) - Total Inferred gold resources increased by
49% to 1.6 Moz - Resource remains open to depth and to the north along strike
- OMZ established as one of highest-grade gold deposits globally
- G2 exploration team remains in growth and discovery mode
Daniel Noone, Chief Executive Officer of G2 Goldfields Inc. stated, “This MRE firmly establishes our Oko Project as both large and comparatively high grade. This, combined with Guyana’s pro-development mining policies, places Oko near the top of undeveloped gold projects. We will continue to leverage our experience, success and knowledge of this emerging district to find and develop more mines for Guyana.”
Mineral Resource Estimate
The mineral resource summary is presented in Table 1 below. Indicated resources total 1.5 Moz at a grade of 3.40 g/t Au and include high-grade, near surface zones (S3, S4, S5) at OMZ of 609,000 oz at an average grade of 10.25 g/t Au within approximately 5 to 370 m from surface, reflecting the favorable vertical zonation of the deposit. Inferred resources total 1.6 Moz @ 2.48 g/t Au and include high-grade, near surface zones at OMZ of 360,000 oz at an average grade of 7.28 g/t Au within approximately 5 to 560 m from surface.
The Resource includes all drilling data obtained up to the end of January 2025, including an additional 188 drill holes totalling 59,154 metres for a total inventory of 587 drill holes within 152,817 metres. The estimate was prepared by Micon International Limited (“Micon”) in accordance with National Instrument 43-101 (“NI 43-101”) with an effective date of March 1, 2025.

Notes to Table 1:
- The effective date of this Mineral Resource Estimate is March 1, 2025.
- The MRE presented above uses economic assumptions for both, surface mining in saprolite and fresh rock and underground mining on fresh rock only.
- The MRE has been classified in the Indicated and Inferred categories following spatial continuity analysis and geological confidence.
- The calculated gold cut-off grades to report the MRE for surface mining are 0.27 g/t Au in saprolite, 0.32 g/t Au in fresh rock and for underground mining is 1.48 g/t Au in fresh rock.
- The economic parameters used are; a gold price of US
$2,281 /oz with a single metallurgical recovery of85% , a mining cost of US$2.5 /t in saprolite, US$2.75 /t in fresh rock and US$75.0 /t in underground. Processing cost of US$12 /t for saprolite and US$15 /t for fresh rock and a general and administration cost of US$2.5 /t. - For surface mining the open pits at Oko and Ghanie use slope angles of 30° in saprolite and 50° in fresh rock.
- Micon's QPs have considered that the transition between the OP mining and UG mining scenarios will result in the need for crown pillars. However, at this time, the crown pillars are considered to be recoverable, therefore Micon's QPs have considered them as part of the Mineral Resource Estimate.
- The OMZ presently has had subcontracted mid-scale miners underground mining operations on the license. G2 Goldfields has provided Micon’s QPs with digitized vertical maps of the voids, as of 2022, and the current mineral resources have been discounted based upon this information. However, there are no updated surveys, maps or production records for the underground mining operations from 2022 to present. G2 Goldfields is of the belief that there are no subcontracted mid-scale miners currently present on the Oko claims.
- The block models for Oko and Ghanie are orthogonal and use a parent block size of 10 m, along strike, 3 m across strike, and 5 m in height. The minimum child block is 2 m x 0.5 m x 1 m respectively.
- The open pit optimization uses a re-blocked size of 10 m x 9 m x 10 m and for the underground optimization uses mining shapes of 10 m long by 10 m high for Oko and 20 m long by 20 m high for Ghanie and a minimum mining width of 2 m.
- The mineral resources described above have been prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum Standards and Practices.
- Messrs. Alan J. San Martin, P.Eng. and William J. Lewis, P.Geo. from Micon International Limited are the Qualified Person (QP) for this Mineral Resource Estimate (MRE).
- Numbers have been rounded to the nearest thousand tonnes and nearest hundred ounces. Differences may occur in totals due to rounding.
- Mineral resources are not mineral reserves as they have not demonstrated economic viability. The quantity and grade of reported Indicated and Inferred mineral resources in this news release are uncertain in nature and there has been insufficient exploration to define any measured resource; however, it is reasonably expected that a significant portion of Inferred Mineral Resources could be upgraded into Indicated Mineral Resources with further exploration.
- Micon's QPs have not identified any legal, political, environmental, or other factors that could materially affect the potential development of the mineral resource estimate.

Zones Remain Open for Further Growth
The OMZ and Ghanie deposits consist of multiple plunging zones of high-grade mineralization that remain open vertically. These zones continue to be successfully targeted in an on-going drill program at Ghanie North and the OMZ Shear 3, where visible gold have been intersected in multiple recent drill holes. Two diamond drill rigs are currently active targeting high-grade plunging mineralization.
Regional Exploration
The G2 team is fully focused on near surface targets in the greater Oko area, including assets proposed to be part of the G3 Goldfields Inc. (“G3”) spin-out. The potential for the discovery of additional gold resources is considered to be excellent. G2 is currently drilling several prominent gold-in-soil anomalies north of the Oko Project which are interpreted to be part of a regional structural break. Additionally, a major soil sampling and mapping program is ongoing on the greater G2 property portfolio.
Data validation
The drilling database used to estimate the Mineral Resources reported in this press release was reviewed by Micon International Limited. A site visit was conducted by Ing. Alan J. San Martin, P.Eng., MAusIMM(CP), to inspect mineralized intervals, alteration assemblages and QA/QC protocols and to conduct field checks of trenches and to validate drill collars. Database verifications consisted of drill logs (including lithology, alteration, weathering), assay certificates, sample intervals, drill hole collars, downhole survey information and QA/QC results validations.
QA/QC
Drill core is logged and sampled in a secure core storage facility located on the OKO 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 quality control/quality assurance program (QAQC). No QA/QC issues were noted with the results reported herein.
