G2 Drills Multiple Near Surface Intercepts in New Oko Discovery Area, Significant Sulphide Mineralization Encountered in Deeper Drill Holes

Patrick Sheridan, Executive Chairman, added, “The extraordinary successes of one of the best exploration teams in the business continues. We are still in the early stages of exploring this emerging gold district and I am entirely confident in our abilities to meaningfully grow the Company’s global gold resources. G2 has first mover advantage in this new mining camp, and thus maintains a very dominant land position with multiple high value targets remaining untested by drilling. The G2 team, led by Dan Noone (CEO) and Boaz Wade (V.P. Exploration), will continue to deliver for shareholders and for the people of Guyana. I am convinced there will ultimately be multiple mines in this district.”

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 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 quality control/quality assurance program (QAQC). No QA/QC issues were noted with the results reported herein.

The MRE was prepared by Micon International Limited with an effective date of March 1, 2025. Significantly, the updated mineral resources lie within an average depth of 665 metres of surface. 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.

Forward-Looking Statements

Article content

This news release contains certain forward-looking statements, including, but not limited to, statements about multiple gold targets have been delineated north of existing resources along a 15km trend in which the Company has stationed four active drill rigs, extensions of these higher-grade zones at depth and shallow strike extensions to the southwest will be the focus of the next phase of drilling, the new zone remains open in all directions, multiple deeper drill holes in the central area have intersected significant widths of highly mineralized core with up to 7% sulphides for which assays are pending, G2 has mobilized equipment and personnel to drill a significant new gold-in-soil anomaly located 4km north of the current drilling campaign, the initial eight-hole program in this new area, the ‘RE Zone’, will commence shortly and assay results from this program can be expected in mid-July. Wherever possible, words such as “may”, “will”, “should”, “could”, “expect”, “plan”, “intend”, “schedule”, “anticipate”, “believe”, “estimate”, “predict” or “potential” or the negative or other variations of these words, or similar words or phrases, have been used to identify these forward-looking statements.
