American Pacific Reports Initial Assay Results from 2023 Drilling at its Palmer VMS Project and Provides Gooseberry Update
NEWS RELEASE
AMERICAN PACIFIC REPORTS INITIAL ASSAY RESULTS FROM 2023 DRILLING AT ITS
PALMER VMS PROJECT AND PROVIDES GOOSEBERRY UPDATE
Vancouver, British Columbia / October 18, 2023 - American Pacific Mining Corp (CSE:
USGD / OTCQX: USGDF / FWB: 1QC) (“American Pacific” or the “Company”) is pleased
to announce that initial assay results continue to highlight the copper -zinc rich nature of
mineralization at the Palmer Project (“Palmer” or the “Project”). Palmer is an advanced-stage,
high-grade volcanogenic massive sulphide-sulphate deposit (“VMS”) located in the Porcupine
Mining District of the Haines Borough, Alaska , US . Constantine North Inc ., a subsidiary of
American Pacific, is the operator for the Project and the US$25.5 million 2023 program has
been funded by joint venture (“JV”) partner Dowa Metals & Mining Co., Ltd (“Dowa”).
The Company has received complete assay results for seven (7) of the 23 drill holes completed
as part of the 2023 resource definition drilling at the Southwall Zones of the Palmer deposit
(see Figure 1).
Highlights:
• CMR23-153 (upper zone 1) intersected 23.4 metres (“m”) of 1.78% copper (“Cu”)
and 13.73% zinc (“Zn”) with elevated gold, silver and barite values (see Table 1),
including 30.16% Zn over 6.2 m (see Photo 1).
• CMR23-152 (upper zone 1) intersected 14.8 m of 1.26 % Cu and 7.68 % Zn, including
up to 7.48% Cu over 1.1 m.
• Zone 1 infill assay results to-date have exceeded expectations with higher grades and
mineralized thickness than currently modeled in the eastern portion of the deposit.
• CMR23-157-01 (lower zone 2-3) intersected 22.9 m of 2.18 % Cu, including 4.23 % Cu
over 5.3 m; demonstrating the potential for significant copper grades and thickness.
• The assay results from these initial infill diamond drill holes are encouraging and support
the mineral resource definition in the Southwall.
“The 2023 resource definition and geotechnical drilling programs at our Palmer project have
been successfully completed,” stated Warwick Smith, CEO of American Pacific. “We are
pleased that significant semi-massive and massive sulphide mineralization has been observed
within the upper (Zone 1) and lower (Zone 2-3) VMS lenses of the Southwall Zone at the Palmer
deposit. Initial assay results continue to highlight the copper-zinc-rich nature of the Palmer
deposit and we look forward to receiving and reporting additional assay results in the coming
weeks.”
2023 Drilling Program
Since drills began turning on June 10, a total of 10,622.2 m have been drilled, representing
87% of the planned infill program and 93% of the planned geotechnical program . With the
additional season end exploration program at regional targets, Christmas/Red Creek, 91% of
the overall program was achieved. The 2023 diamond drill program targeted high-priority areas
in two unique mineralized lenses in the Southwall Zone. Two diamond drill rigs were dedicated
to the infill drill program with a third diamond drill rig focused on hydro -geotechnical drilling
around the immediate deposit area.

The initial 2023 results build the JV partners’ confidence in the geologic interpretation of the
VMS lenses within the Southwall Zone , while gaining valuable geotechnical data of the
surrounding wall rock. The insight s gained from this program will guide subsequent drilling
campaigns to support future feasibility-level studies of the Palmer de posit and discovery -
focused drilling throughout the region.

Southwall Zone 1 (upper): Assay results for four (4) drill holes have been received (see Table
1). Initial assay results indicate a zinc-barite rich eastern side to Zone 1 with a transition to more
copper-rich mineralization in the center of the lens. Current assays in the eastern portion
indicate a thickening of the modeled Zone 1 lens with zinc grades o ver varying lengths (see
Figure 2).

showing zinc (left) and copper (right).
Southwall Zone 2-3 (lower): Assay results for the first three (3) drill holes have been received
(see Table 2) . Drill holes CMR23 -151 and CMR23-154 targeted a gap in the current block
model, where copper-zinc stringer mineralization was intersected in addi tion to valuable
structural data. CMR23-157-01 was a planned directional drill hole that intersected significant
copper-rich mineralization within two distinct massive sulphide lenses separated by mineralized
massive barite and capped by mineralized barite and chert.
Assay results continue to be received and further updates will be provided as results are vetted
and interpreted.

Gooseberry Project Update
The Company completed 10 of 29 proposed drill holes this summer to begin testing regional
“wildcat” exploration targets in the pursuit of discovering additional veins across the 100%-
owned Gooseberry Project . GB23 -002 intersected a 19.8 m interval of lower grade calcite -
quartz veining with the final 4.6 m of the hole returning undetectable gold and silver values. The
mineralization at Gooseberry is classic high -level epithermal gold and silver in quartz/calcite
veins. Wall-rock on either side of the veins becomes barren very quickly. There were no other
significant assay results to report. The program was terminated early due to drilling / ground
condition challenges. The Company decided to conserve capital and revisit the other regional
targets after integrating the new data and refining its target concepts beyond the known past -
producing Gooseberry vein.
Quality Assurance (QA) and Quality Control (QC)
The JV implements strict Quality Assurance and Quality Control protocols at Palmer covering
the planning and placing of drill holes in the field; drilling and retrieving drill core; drillhole
surveying; core transport to the Palmer Camp; core logging, sampling and bagging of core for
analysis; transport of core from site to ALS Laboratory in North Vancouver BC for sample
preparation and analysis; recording and final statistical vetting of results.
Sampling procedures - The Company's QA/QC drill core sample protocol consists of
collection of samples over a minimum 0.3 m interval to a maximum 1.5 m interval (depending
on the lithology and style of mineralization) over the mineralized portions of the drill hole. The
drill core sample is cut in half with a diamond saw, with half of the core placed in individual
sealed polyurethane bags and the remaining half securely retained in the original core box for
permanent storage. Drill core samples are shipped by transport truck in sealed woven plastic
bags to ALS Geochemistry Analytical Lab facility in North Vancouver, BC for sample
preparation and analysis. ALS Geochemistry meets all requirements of International Standards
ISO/IEC 17025:2017 and ISO 9001:2015. ALS Global operates according to the guidelines set
out in ISO/IEC Guide 25.
Gold was determined by fire -assay fusion of a 30 g sub -sample with atomic absorption
spectroscopy (AAS). Various metals including silver, gold, copper, lead and zinc were analyzed
by inductively -coupled plasma (ICP) atomic emission spectroscopy, following multi -acid
digestion. The elements copper, lead and zinc are determined by ore grade assay for samples
that return values >10,000 ppm by ICP analysis. Silver is determined by ore -grade assay for
samples that return >100 ppm by ICP analysis. Barium (BaO) analysis utilized lithium borate
fusion into fused discs for XRF anal yses, with BaO converted to BaSO4 (barite) using a
conversion factor of BaO x 1.52217. Density measurements were determined at the Project site
by Constantine personnel on cut core for each assay sample.
The Company maintains a robust QA/QC pro gram that includes the collection and analysis of
duplicate samples and the insertion of blanks and standards (certified reference material). In
addition, prepared samples, sample replicates, duplicates and internal reference materials are
routinely used as part of ALS Geochemistry’s internal quality assurance program.
