American Pacific Commences Drill Program at the Madison Copper-Gold Project in Montana
American Pacific Commences Drill Program at the Madison Copper-
Gold Project in Montana
Vancouver, British Columbia – April 22, 202 5—American Pacific Mining Corp. (CSE: USGD /
OTCQX: USGDF / FWB: 1QC) (“American Pacific” or the “Company”) is pleased to announce that
drilling has commenced at its 100% -owned Madison Copper -Gold Project (“ Madison” or the
“Project”) located in Silver Star, Montana. This marks the start of the Company’s 3,000-metre
drill program following the receipt of updated permit approval earlier this year.
The drill program is designed to test five priority target areas identified through extensive data
integration and analysis. These targets include porphyry concepts and multiple skarn extensions
both laterally and down plunge of known mineralization . The program will also focus on near -
mine extension drilling at the Broadway mine area , where historic production totalled 144,000
ounces of gold from surface oxide mineralization, between 1880-1950.1 (see Image 1 and Figure
1). No drilling has been done in the area since mining operations concluded and sulfide
mineralization, which was not considered economic during the historical mining period, has
never been tested. The planned drilling also includes select regional shallow discovery targets.
Collectively, the 2025 drilling is taking aim at high impact targets that have the potential to deliver
significant value by demonstrating the scale of the system well beyond the ar eas historically
mined.
Exploration Highlights:
• The drill campaign will leverage insights gained from the Silverstar Fault Complex, a key
structural feature identified as a critical control on mineralization.
• Induced Polarization (IP) surveys2&3 have revealed compelling geophysical anomalies along
the fault complex, guiding the targeting of skarn, porphyry, and orogenic mineralization in
previously undrilled areas.
• Porphyry Potential: Drilling to date at Madison has primarily targeted high-grade copper-
gold skarn mineralization within the upper 300 metres from surface. Limited drilling has
penetrated deeper levels, leaving the porphyry potential largely untested. The Company
has four drill holes planned to test two compelling porphyry targets: (1) a down -plunge
target directly beneath the historical Madison Mine, where increasing mineralization and
modeling suggest proximity to a source; and (2) a regional target to the southwest where
coincident IP chargeability, zones of magnetic highs and lows, and potassium radiometric
highs, collectively support the potential of a mineralized source . These deeper holes
represent a significant upside opportunity to vector into a causative intrusive source.

Eric Saderholm, P.Geo ., Managing Director of Exploration and Qualified Person for the Project,
commented: “This drill program represents a comprehensive analysis of years of meticulous
exploration and preparation. With these well -defined targets, we believe this campaign will
provide meaningful insights into Madison’s potential as a district-scale copper-gold system.”

The red outline within Figure 1 highlights the projection of the favourable contact zone between
the Madison limestone and the quartz monzonite intrusive, which has returned high -grade
copper-gold values in surface sampling. This critical contact is interpreted to be a contributing
control on mineralization and remains largely untested along strike and at depth. While the figure
projects historic Broadway mine workings, the drill holes shown are southern step -outs located
up to 50 metres south of known workings. The Company interprets tha t historical mining may
have ceased upon encountering sulfide mineralization at depth or due to a lack of processing
technology at the time, which presents a compelling opportunity to test below and along
unmined extensions of this contact zone.

About the Madison Copper-Gold Project
The Madison Project was host to small-scale production that concluded in 2012, with 2.7 million
pounds of copper produced at grades ranging from 20 -35% copper. Subsequent drilling at
Madison in 2017 included 30.18 metres of 24.50 g/t gold and 0.39% copper and 10.97 metres of
41.65 g/t gold and 0.38% copper (UG17 -05 and UG17 -06, respectively). Full disclosure can be
