G2 Goldfields Significantly Increases Gold Ounces in an Updated Mineral Resource Estimate at the Oko Project in Guyana

03.04.2024  |  GlobeNewswire

TORONTO, April 03, 2024 - G2 Goldfields Inc. ("G2" or the "Company") (TSXV: GTWO; OTCQX: GUYGF) is pleased to announce an updated Mineral Resource Estimate ("MRE" or "Resource") within the Company's 27,719-acre OKO project, Guyana. The updated MRE is comprised of a discrete high-grade resource for the Oko Main Zone (OMZ) and a disseminated bulk mineable resource for the Ghanie Zone. Total contained gold increased by 69% to 2.0 million ounces. Total indicated gold increased by 320% to 922,000 ounces.

The total combined open pit and underground Resource reported in the MRE for the OMZ includes 686,000 ounces (oz) of gold (Au) in Indicated Resource contained within 2.36 million tonnes (Mt) grading 9.03 grams per tonne (g/t) Au, with an additional 495,000 oz of gold in Inferred Resources, contained within 2.41 Mt grading 6.38 g/t Au.

The total combined open pit and underground Resource reported in the MRE for the Ghanie Zone includes 236,000 ounces (oz) of gold (Au) in Indicated Resource contained within 3.34 million tonnes (Mt) grading 2.20 grams per tonne (g/t) Au, with an additional 604,000 oz of gold in Inferred Resources, contained within 12.22 Mt grading 1.54 g/t Au.

The MRE was prepared by Micon International Limited with an effective date of March 27, 2024.

Patrick Sheridan, Executive Chairman, comments, "The OMZ has proven to yield exceptional high grade at mineable widths as we drill deeper, and Ghanie is taking shape to be highly complementary to the OKO gold system. We will continue to aggressively explore the Oko to Aremu trend and anticipate an updated resource in Q4."

Ghanie Zone Maiden MRE

This Maiden Mineral Resource Estimate at Ghanie signifies a major shift towards realising the district-scale nature of the OKO gold system. The Ghanie Zone represents a disseminated bulk mineable and open-pittable deposit which strongly complements the adjacent high-grade underground deposit at the OMZ.

Ghanie South (GS), Central (GC), and North (GN) all remain open with substantial depth potential. A recent high-grade discovery at Ghanie North (GDD-93) returned 24.5m @ 5.3 g/t Au from 124 metres downhole (including 4.5m @ 25.2 g/t Au from 134.5m). This intercept is indicative of additional near surface mineralization and there is much evidence to suggest the potential for further zones to be discovered along the 1.75-kilometre strike.

OMZ Updated MRE

Since April 2022, the Oko Main Zone (OMZ) has been further defined with additional Indicated resources confirmed. The OMZ is characterised by shear vein hosted mineralization with spectacularly high grade. Notably, the Shear 5 Indicated Underground Resource averages 15.78 g/t Au. The Resource at the OMZ has been diluted to a minimum mining width of 2 metres.

Exploration Update

The Company's geological model is evolving and becoming more predictive, leading to regular discoveries along the 20-kilometre-long Oko-Aremu trend. Approximately 500 metres to the North-West of the OMZ lies the recent NW OKO discovery where NWOD-22 intercepted 15.0m @ 6.3 g/t [See Press Release dated February 13, 2024]. The company will be introducing an additional drill rig at NW OKO.

The Company's mandate is to add value through additional discoveries to complement the continuing expansion of the OMZ and Ghanie resource with a focused on exploring near surface mineralization. In April 2024, the Company is to commence drilling at Tracy, located a further 5-kilometres along strike. Subsequently, G2 will initiate drilling at Aremu.

Dan Noone, CEO, comments, "the updated MRE provides an excellent platform from which to continue district wide target definition and drill programs in parallel with resource expansion at OMZ and Ghanie." To this end, the Company is targeting a further resource estimate update in Q4 2024.

Notes:

  1. The effective date of this Mineral Resource Estimate is March 27, 2024.
  2. The MRE presented above uses economic assumptions for both, surface mining in saprolite and fresh rock and underground mining on fresh rock only.
  3. The MRE has been classified in the Indicated and Inferred categories following spatial continuity analysis and geological confidence.
  4. The calculated gold cut-off grades to report the MRE for surface mining are 0.33 g/t Au in saprolite, 0.39 g/t Au in fresh rock and for underground mining is 1.80 g/t Au in fresh rock.
  5. The economic parameters used a gold price of US$1,900/oz with a single metallurgical recovery of 85%, 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.
  6. For surface mining the open pits at Oko and Ghanie use slope angles of 30° in saprolite and 50° in fresh rock.
  7. The MRE has been classified in the Indicated and Inferred categories following spatial continuity analysis and geological confidence.
  8. The block models for Oko and Ghanie are orthogonal and use a parent block size of 10 m x 3 m x 10 m with the narrow side across strike (East-West) and a minimum child block of 2 m x 0.5 m x 1 m.
  9. The open pit optimization uses a re-blocked size of 10 m x 9 m x 10 m and for the underground optimization uses stopes of 20 m long by 20 m high and a minimum mining width of 2 m.
  10. The mineral resources described above have been prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum Standards and Practices.
  11. Messrs. Alan J. San Martin, MAusIMM(CP) and William J. Lewis, P.Geo. from Micon International Limited are the Qualified Persons (QPs) for this Mineral Resource Estimate (MRE).
  12. Numbers have been rounded to the nearest thousand and differences may occur in totals due to rounding.
  13. 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.
  14. The QPs are not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, marketing or other relevant issue that could materially affect the mineral resource estimate.

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 Alan J. San Martin, 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.
