Gold79 Mines Ltd. announced 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.

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. 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 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). 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 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. 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.

A track-mounted excavator 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.
