American Pacific Mining Reports High-Grade Samples
from Madison Copper-Gold Project
Vancouver, British Columbia / February 8, 2023 - American Pacific Mining Corp (CSE:
USGD / OTCQX: USGDF / FWB: 1QC) (“American Pacific” or the “Company”) is pleased
to report high-grade gold (“Au”) and copper (“Cu”) rock chip samples from a program conducted
by Kennecott Exploration, a division of the Rio Tinto Group, at the Madison Copper-Gold Project
(“Madison” or “the Project”) in Montana. Madison is under a joint-venture earn-in agreement,
whereby Rio Tinto may earn up to 70% of the project by spending US$30 million.
Highlighted Sample Results:
• 40485321: 9.93 g/t Au; 3.40 g/t silver (“Ag”); 0.08% Cu
• 40485246: 13.30 g/t Au; 7.83 g/t Ag; 0.04% Cu
• 40485201: 12.35 g/t Au; 5.76 g/t Ag; 0.01% Cu
• 40485221: 32.40 g/t Au; 39.60 g/t Ag; 0.02% Cu
• 40485233: 0.13 g/t Au; 1.49 g/t Ag; 0.26% Cu
• 40485284: 7.36 g/t Au; 38 g/t Ag; 6.90% Cu
A total of 73 rock chip samples were collected from 5 specific exploration targets: the Archean
Section, America Pit; Devonian Jefferson Dolomite; Hudson Mine; and Western Skarn Contact,
each of which contained high-grade samples (see Fig 1).
“American Pacific is particularly encouraged by the high -grade gold values obtained from this
program which confirm a large mineralized system,” stated President Eric Saderholm. “Surface
gold and copper mineralization occurrences within this system have been identified over an 11
square kilometre area. A major thrust fault zone, the Silver Star Fault, dissects the property
placing older Precambrian rocks against and above the favourable Paleozoic carbonates and
the Radar Creek intrusive complex, the probable source of the Madison mineralization . The
Silver Star Fault system appears to be related to a deep crustal fault zone that connects to the
Butte porphyry deposits located 38 kilomet res to the northwest. All five targets present
significant exploration possibilities within the district . The Archean target is virtually untested
and is of particular interest to our geologists due to the pronounced geophysical anomalies and
the coincident historic gold values of up to 48.5 grams per tonne."

Archean Section
Seventeen samples were collected in the Archean Section, primarily in and around historic
prospect pits. Several quartz and carbonate veins were sampled. The quartz veins located
within the Archean section are steeply dipping and generally trend east-west.

American Pit
Three samples were collected on a ridge north by northwest of the American Pit. The American
Pit was mined in the 1970s by open -cut mining methods along the Rader Creek -Madison
Limestone contact. The American Pit marks the surface expression of the Madison Skarn
deposit. Mineralized endo-skarn of the Rader Creek granodiorite hosts the deposit. High-grade
quartz sulfide veins are found outside the pit boundary.
Table 2 Notable Assay Results – American Pit
Rio Tinto has conducted several successful sampling program s in the American Pit area, with
results ranging from 0.25 g/t Au to 124.50 g/t Au. Copper values have ranged from 0.006% Cu
to 0.264% Cu. (see December 9, 2021 press release).
Devonian Jefferson Dolomite
Twenty-nine rock samples were collected along the footwall of the Silver Star Fault within the
Devonian Jefferson Dolomite. These samples were collected from several historic prospect pits
and scattered outcrops. The Jefferson in this area shows strong limonite -jasperoid vein and
veinlet mineralization, and high-grade Au values track with the jasperoids. The Jefferson
Dolomite can be a great host rock due to contained relic hydrocarbon content mixing with
metalrich hydrothermal fluids.

Hudson Mine
Fifteen samples were collected in and around the Hudson Mine workings. The Hudson Mine
was a past producer of high -grade Au-Cu skarn mineralization hosted in the Rader Creek
granodiorite-Madison limestone contact.

Western skarn contact
Six samples were collected along the western edge of the Madison Skarn. Here the sediments
form a thin skin covering the granodiorite -sediment contact with widespread hornfels and
scattered structurally controlled skarn occurrences. Numerous historic prospects can be found
on these structural skarn zones.

QAQC Procedures
QAQC samples were inserted into every laboratory batch commensurate with the stage of
exploration and sample type in the batch. Rio Tinto uses blanks, certified reference materials
and field duplicate samples for QAQC. Blank material is a >2cm diameter was hed granitic
gravel material from landscape supply stores. Certified reference materials are either
commercial standards from Ore Research Pty Ltd or in-house standards created from Bingham
Canyon Mine material and certified through a robust round robin pr ocess signed off by an
independent geochemist. Field duplicates are created at the time of original sampling and are
designed to replicate the primary sample. In addition to RTX -inserted QC samples, ALS
includes in-laboratory QC as preparation duplicates (crush and pulverizer duplicates), reagent
blanks and a wide range of certified reference materials.
Engage Market Provider
The Company also announces that it has engaged Petergrandich.com/blog as its marketing
provider for an initial term of 6 months and has agreed to pay US$60,000 for its services.
