NEWS RELEASE
American Pacific Mining Reports Assay Results, Including 12.13 g/t Gold over 1.52
Metres, from the Tuscarora Project
Vancouver, British Columbia / November 22, 2022 - American Pacific Mining Corp (CSE:
USGD / OTCQX: USGDF / FWB: 1QC) (“American Pacific” or the “Company”) is pleased
to provide a project update and assay results from the Tuscarora Project (“Tuscarora”) or (“the
Project”).
The Company completed 33 shallow reverse circulation (“RC”) drillholes at Tuscarora for a total
of 5,515 metres (“m”) across several different target areas. Drilling at the South Navajo area
defined a potential third gold zone below known mineralization and drilling and sampling along
the Modoc Vein swarm has highlighted the potential for a new gold -bearing sulfide system in
an area that has very limited historical drilling.
Highlights from the 2022 Tuscarora Drill Program:
• South Navajo: TS22-23 and TS22 -32 were designed to test for additional gold
mineralization below known stacked gold zones:
o TS22-32 intersected 2.48 grams per tonne (“ g/t”) gold (“Au”) over 13.72 m,
including 12.13 g/t Au over 1.52 m (from 193.55 m).
o TS22-23 deviated to the south , but still intersected 2.94 g/t Au over 1.52 m
starting from a similar 192.02 m downhole, as well as 2.07 g/t Au over 2.29 m
and 1.18 g/t Au over 3.05 m further up-hole.
o This third interpreted lower gold zone remains open to the north and south.
• Modoc South Target: TS22-25 intersected 6.89 g/t Au and 29 g/t Ag over 1.52 m
within a broader envelope of lower grade gold (0.34 g/t Au over 45.72 m starting from
161.54 m):
o All three (3) drillholes at Modoc South intersected broader lower-grade gold
values in sulfide-bearing volcanic host rocks (TS22-27: 0.38 g/t Au over 94.49 m),
highlighting the potential for a significant new style of gold mineralization to
pursue at Tuscarora.
• Modoc North Target Area: Several shallow gold intercepts in an area with limited
drilling that remains wide open:
o TS22-28 intersected 2.44 g/t Au over 4.57 m starting from surface.
o TS22-11 intersected 4.46 g/t Au over 1.52 m starting from 1.52 m.
o TS22-16 returned 0.78 g/t Au over 10.67 m starting from 56.38 m.
o Seven rock chip channel samples within this target area returned values ranging
from 2.00 to 13.18 g/t Au and a gaudy visible gold grab sample was recently taken
from a nearby prospect pit (see Figure 2).
American Pacific’s President, Eric Saderholm, commented: “Defining a third gold zone at South
Navajo and drilling into a new gold-bearing sulfide system at Modoc are both very encouraging
developments from our modest drill program at Tuscarora. The relatively shallow sulfide
mineralization at Modoc is particularly intriguing as this area has very limited historical drilling
and represents a new target type that we will pursue in subsequent drill campaigns.”

Background and Interpretation of Results
The Phase I Tuscarora program focused on infill at South Navajo and true exploration drilling
on the untested Modoc and Repo targets, located in the south and west project areas.
Several interesting results were encountered. Unexpected longer and consistent intercepts of
lower grade mineralization have opened the potential of a broader, more bulk-mineable style
of mineralization within the volcanic hosts, in addition to the obvious vein potential in the
project area. These intercepts occur in both oxide and sulfide mineralization.
TS22-09 to TS22 -13 were drilled on a fan , meaning all were drilled from the same starting
location, and the highest grade returned was 1.52 m of 4.46 g/t Au. It was among lower grade
thicker intervals as witnessed in TS22-09 with 13.71 m averaging 0.61 g/t Au starting at a 7.62m
depth. A second fan at Modoc included holes TS22-14 to TS22-17 and identified continuity at
depth and along strik e of a quartz vein system evidenced in surface mapping and prospect
pits. The best interval was 10.67 m at 0.78 g/t Au, including 3.05 m at 1.27 g/t Au in TS22-16.
Recently interpreted project-wide CSAMT geophysical data highlighted additional anomalies in
the untested Grand Prize, Payday and East Pediment zones, located in the eastern portion of
the property. These strong anomalies were expected, but poorly defined until the CSAMT
results were received as, similar to South Navajo, they are covered by a re latively thin gravel
cover and have no surface expression. These targets are now better refined and lay in an area
that was not a part of the original Phase I permit. An addendum to the Notice of Intent permit is
in process and a Phase II program has been designed to test these promising new targets in
early 2023.
Additionally, and possibly more regionally significant, two holes in the Modoc area were drilled
to sufficient depth to encounter the older (Paleozoic) basement rocks located below the host
volcanic units. These deeper rocks consist of quartzites and siliciclastics of the Ordovician
Valmy and Vinini Formations. These holes encountered strong sulfide mineralization and
anomalous gold values. This is interesting for several reasons. The Valmy -aged rocks are the
capping units above the stronger mineralization along both the Carlin Trend and the nearby
Jerritt Canyon deposits. Below these “upper plate” formations lay the favourable “lower plate”
carbonate-rich units, including the Rodeo Creek, Roberts M ountains, Popovic and Hanson
Creek Formations. These regionally well -known formations host the bulk of the ore
mineralization along these prolific trends and account for approximately 100 million ounces of
historically mined and current gold reserves.
The age of the Tuscarora volcanic rocks and mineralization is approximately 40 million years
making it roughly synchronous with the Carlin and Jerritt Canyon mineralization ages. The Mt
Blitzen caldera is the known source gold and silver mineralization at Tuscarora and the contact
of this strong metal system with the deeper “lower plate” rocks provides for a very intriguing
target.
An entirely new, and unexpected, Carlin -style mineralization potential has emerged from this
drilling campaign and a future, deeper drilling program is justified to test these newly emerging
target concepts.

Tuscarora was historically a placer mining district, and the presence of visible and coarse free
gold has been documented historically and recognized again by American Pacific during its
recent exploration work in the district . This “nugget-effect” at projects like Tuscarora, that can
contain valuable large gold particles (or “nuggets” – as seen above in Figure 3) can result in
concentrations of gold that are challenging to accurately represent with tr aditional assay
techniques.
Based on visual observations in the field during the Tuscarora drill program and onsite sluice
box sampling using material not caught in a standard RC sample, the Company believes that
in several cases the standard assay ing process that was used for all reported assays herein
did not adequately represent the coarse free gold that was observed within brecciated quartz
samples at Tuscarora. As a result, the Company has engaged with ALS Laboratories and plans
to complete Photon Assays on select samples from the Tuscarora program.
