Gold79 Mines Ltd. announced that it has a completed a mapping and sampling program of the 200 foot level of the Tyro mine. Results from the chip-channel sampling returned similar grades and widths to the fall 2021 drill program, approximately 600 metres south of that drilling. Sampling highlights: 25.4m at 2.53 g/t gold 12.7m at 2.44 g/t gold .

The work has detailed about 400 metres of mine workings along a mineralized N30oE trend which accessed 200 metres of the Tyro vein system. Along this portion of the vein system, which has been mapped for over 1 kilometre on the surface, a multistage hydrothermal breccia is flanked by parallel, subvertical quartz-chalcedony-adularia veins up to a metre in width. One crosscut has revealed that the breccia/vein complex measures 25.4 metres at 2.53 g/t Au and a partially exploited mineralized zone about 30 metres wide contains 12.7 metres at 2.44 g/t Au and 5.3 metres at 2.63 g/t Au.

Within this interval, about 12 metres of the vein complex had been exploited suggesting higher grades within this broad 2.5 g/t Au interval . Production records from the Tyro mine have not been identified. Prior to 1923, the Tyro shaft was sunk to a depth of 500 feet and limited development occurred on the 200L and appears to have followed high-grade veins parallel to the breccia zone.

Development, aside from the shaft, did not occur below the 200L. As recently as the 1980's, mining occurred along the surface exposures of the vein over a strike distance of about 400 metres and a decline was sunk below the southern breccia zone . Stopes here suggest that mining was very selective and the majority of the mineralized rock, as observed on the 200L and in the 2021 drilling campaign, was left in place.

Sampling occurred approximately 600 metres from the drilling completed in fall 2021. Sampling on the Tyro 200L resulted in 58 chip samples taken continuously, where possible, across mineralized exposures . Chip samples ranged up to 10.47 g/t Au with 74% containing greater than 1 g/t Au., several composite samples greater than 5 metres in width include: has identified a broad zone of quartz-chalcedony-adularia-calcite- veins and multi-stage hydrothermal breccia trending N30oE and dipping 90o +/-10o.

The mineralized zone in the mine is up to 30 metres wide and likely extends further to the east as evidenced by surface exposures . Veins are a fine-grained mixture of chalcedony and adularia and are locally banded; calcite and minor fluorite cut the banded veins. The breccia body is composed of multiple stages of quartz and chalcedony with widespread banding in the crosscutting veinlets.

Fragments are composed of weakly to strongly veined Precambrian granite fragments and earlier formed vein fragments. Sulfides were not visible in the breccia and veins and silver values are less than 25 g/t Ag; Cu, Pb, Zn, As, Sb and Hg are negligible. Because gold was identified in both the veins and breccia, a specific mineral event associated with gold has not been identified.

In the nearby Oatman district, at least 3 gold events have been identified. Based on the preliminary assays received from the Fall 2021 drill program at Tyro, the Company took the decision to sample additional intervals from the already released holes. Of note, hole GC21-14 is now 35.2m at 1.25 g/t Au .

Additional samples were assayed from holes GC21-13 and GC21-15, but there were no material changes to the mineralized envelopes for those holes. Additional assays are pending from hole GC21-16.
