Gold79 Completes Trenching of the Tyro Main

Zone at the Gold Chain Project

Ottawa, Ontario--(Newsfile Corp. - May 27, 2024) - Gold79 Mines Ltd. (TSXV: AUU) (OTCQB: AUSVF)

("Gold79" or the "Company") is pleased to announce that it has completed a trenching program along

the Tyro Main vein including mapping and sampling as announced on May 2, 2024. A total of 15

trenches were completed over 358 metres. Results are pending from the 217 samples taken (Figure 1).

Assay results are expected in 4 to 6 weeks.

Preliminary results from the work completed include:

Three trenches were cut at or a little south of the intersection of the White Spar Fault and Tyro Main

Zone where 2023 drilling returned 9.1m of 51.1 g/t Au (Figure 1; GC23-28). Trenching has

provided additional insight into the emerging structural model which will guide future drilling to

confirm and define the high-grade intercept.

Trenches and isolated vein samples adjacent to the open pit reveal that extensive banded

chalcedony-adularia veins form a broad envelope to the central veins up to 50 meters wide with

less than 20% exploited historically.

Surface discontinuities in the northern Main Tyro vein have been trenched. The visible results

suggest better continuity of the quartz veining along strike than originally observed.

Trench 13 (Figure 1) has identified several meters of silicified rock with moderate to strong quartz

veining extending the known vein an additional 50 meters beyond the historical mine workings and

near the end of the patented claim (Tyro claim).

Derek Macpherson, President and CEO stated, "

Completion of the Phase 1 trenching program at our

Tyro Main vein will provide us with important data needed to optimize the design of our Fall, 2024

drilling campaign. The acquisition of detailed geologic information, and eventually the gold assays,

will allow Gold79 to better understand the high-grade results from the 2023 drilling campaign and the

intersection of the White Spar and Tyro structural corridors.

Preliminary Interpretation

Description of the trenches has provided Gold79 with greater confidence in the emerging geologic

model. It is now clear that gold-bearing veins northeast of the intersection with the White Spar fault

(Figure 1) are guided by the Tyro structure and dominantly display a NE to ENE trend as defined by the

overall trend of the Tyro vein system. All veins are steeply dipping both to the northwest and southeast

(as observed in Figure 2). The entrance of the White Spar fault corridor from the north reveals (Trenches

T1 thru T3) a pronounced change in the vein's orientation to a series of NS to NNW en echelon veins

indicating that both the White Spar and Tyro structures were originally pre-mineral in age and the

resulting network of intersecting veins provide a column of high permeability and favorable exploration

conditions at depth. Fault movement along the White Spar system (N-S) continued until after the

mineralizing events resulting in the intense fracturing and displacement of the Decimal Hill area veins

and breccia southwest of the noted intersection (Figure 3).

Program Methodology

A track-mounted excavator (Figure 2) was utilized in the trenching program and when necessary, a

pneumatic hammer was employed for unfractured rock. Once the trench was cut, all rock exposures were

cleaned and geologically defined sample intervals were marked. Samples were collected along lines or

channels utilizing hammers and chisels. Samples were bagged, labeled and tagged on site and stored

in Gold79's secure sample facility in Bullhead City. After sampling, the trenches were mapped and

photographed with blanks and standards inserted prior to shipment. All samples were delivered to the

lab by a Company representative.

All aspects of the program, including sampling, were supervised

and/or conducted by Gold79's Vice President, Exploration.

Financing Update

Further to its press release of April 11, 2024, the Company announces that it is extending the final

closing date of its non-brokered private placement financing by a period of up to thirty days to June 26,

2024. The first closing raising gross proceeds of $718,250 was announced on May 6, 2024.

Qualified Person / Quality Control and Quality Assurance

Robert Johansing, M.Sc. Econ. Geol., P. Geo., the Company's Vice President, Exploration is a qualified

person ("QP") as defined by NI 43-101 and has reviewed and approved the technical content of this

press release. Mr. Johansing has also been responsible for all phases of the Phase 2 drilling program

and Phase 1 trenching program including sample collection, labelling, bagging and transport from the

project to American Assay Laboratories of Sparks, Nevada.

Samples were then dried, crushed and

split, and pulp samples were prepared for analysis. Gold was determined by fire assay with an ICP

finish, over limit samples were determined by fire assay and gravimetric finish. Silver plus 34 other

elements were determined by Aqua Regia ICP-AES, over limit samples were determined by fire assay

and gravimetric finish. Standard sample chain of custody procedures were employed during field work

and the drilling campaign until delivery to the analytical facility.
