Gold79 to Commence Trenching of the Tyro Main Zone at the Gold Chain Project
Gold79 to Commence Trenching of the Tyro
Main Zone at the Gold Chain Project
Ottawa, Ontario--(Newsfile Corp. - May 2, 2024) - Gold79 Mines Ltd. (TSXV: AUU) (OTCQB: AUSVF)
("Gold79" or the "Company") is pleased to announce that it has finalized the design for its systematic
trenching program along the Tyro Main Zone to follow-up the high-grade drill intercepts from 2023 and
better understand the gold distribution along strike. Work is expected to start the week of May 6, 2024.
The key objectives of this program are:
Better understand the intersection of the Whitespar Fault and Tyro Main Zone where 2023 drilling
returned 9.1m of 51.1 g/t Au (GC23-28). Most of this structural intersection is concealed with
material from historical mining activities.
Provide an improved understanding of gold grade distribution across the vein complex and along
the one kilometre of strike of the Tyro Main Zone for future resource calculation.
Provide the data needed to determine the scale and identify the hole locations for the follow-up
drilling program, the anticipated next step for resource definition.
Derek Macpherson, President and CEO stated, "
When Gold79 announced, an Exploration Target of
15.6 to 31.2 Mt grading 1.5 to 2.5 g/t gold, at the Tyro Main zone, the Company also laid out a short,
low-cost path to develop a maiden resource. This trenching program is the first step in establishing a
resource that is expected to be substantially larger and much higher-grade than the nearest producing
mine in the district
." Mr. Macpherson continued, "
Additionally, this work will allow us to better
understand the high-grade zone intersected in our most recent drill program, which returned a multi-
ounce intercept in the last hole of the program
."
The potential quantity and grades are conceptual in nature. There has been insufficient
exploration drilling to define a mineral resource and it is uncertain if further exploration will
result in the Exploration Target being delineated as a mineral resource.
Gary Thompson, Executive Chairman, stated, "
We are excited to get back to work on the Gold Chain
Project. The Tyro Main Zone is an obvious gold target where we have confidence that we can quickly
define a maiden resource, given the grade and continuity of mineralization identified from work to
date. We highlight that the Tyro Main Zone is just one kilometre of the over three kilometre Tyro vein
system; and, that the Tyro vein system is just one of three multi-kilometre gold targets on the property
(see Figure 3).
"
Trenching Methodology and Planned Trenches
The proposed trenching program, located in Figure 1, will consist of 12 trenches for a total of over 400
metres and 250 samples (Table 1). Following the excavation of each trench (18-inch bucket and
pneumatic hammer), the site will be cleaned, photographed, mapped and sampled in a manner that
provides the highest quality data possible. All aspects of the program, including sample transport, will be
supervised, and conducted by Gold79's Vice President, Exploration.

Previous Work at the Tyro Main Zone
The Tyro vein system is a northeast-trending vein system exposed in the core of the Katherine horst. This
portion of the vein system, the Tyro Main Zone, has been mapped and partially sampled over a strike of
about 1km and drilled in two Reverse Circulation campaigns during 2021 and 2023 (Table 2). Previous
results were highlighted by 9.1m at 51.1 g/t gold and 44.2m at 2.0 g/t gold in the most recent drill
program. Historical mine workings (circa 1920 to 1941) have been mapped a sampled and, in
conjunction with the drill intercepts, present Gold79 Mines an opportunity to define a surface to near-
surface gold resource (Figure 2) as outlined in the Company's
January 22, 2024 press release

Gold Chain Project and the Black Mountain Gold Belt
The Gold Chain Project, located in Mohave Co., Arizona, is comprised of a series of gold-bearing veins,
breccia and stockwork bodies hosted in or near Miocene rhyolitic dikes that have invaded Miocene
volcanic rocks or underlying Precambrian granite (Figure 3). Vein material is composed of several
quartz-chalcedony-adularia-calcite stages forming discrete veins to broad, up to 60 metres wide,
sheeted veins, hydrothermal breccia and veinlets. These gold occurrences are part of a regional gold
province which covers an area measuring about 100km (N-S) by 30km between the Colorado River and
the Black Mountain range. The province is heretofore referred to as the Black Mountain Gold Belt
(BMGB) and includes the Oatman district located about 15km south of the Gold Chain project. This
province of Au-Ag-bearing epithermal veins is defined by high gold values, i.e. >8 g/t Au, low Ag/Au
ratios of about 5, low sulfide content (<1%), low base metal values and low pathfinder element (As-Sb-
Hg) contents. The age of these deposits is 16 to 17 Ma and formed prior to the initiation of Basin and
Range faulting after 16 Ma. About 3M ounces of gold have been produced from this underexplored
province owing to the development of the Colorado River Extensional Corridor (CREC) where normal
faulting has served to conceal the 'boiling' horizon.

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
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 was employed during field work and the drilling campaign until
delivery to the analytical facility.
