American Pacific Samples up to 45.1 g/t Gold, 6.9% Copper and Significantly Expands Mineralized Footprint at Madison
American Pacific Samples up to 45.1 g/t Gold, 6.9% Copper and Significantly
Expands Mineralized Footprint at Madison
Vancouver, British Columbia – September 4, 2025 — American Pacific Mining Corp. (CSE: USGD
/ OTCQX: USGDF / FWB: 1QC) (“American Pacific” or the “Company”) is pleased to announce
the successful completion of its Summer 2025 surface sampling field program at the Madison
Copper-Gold Project (the “Project”) in Montana, USA.
Results confirm the presence of additional high-grade skarn -style mineralization at surface,
along with polymetallic and porphyry -style indicators across the district , which has now been
expanded to a 4-kilometre by 2-kilometre footprint. These findings strengthen the case for
Madison as a large, fertile hydrothermal system hosting multiple mineralization styles, with near-
term drill targets aimed at both shallow and deep-seated mineralizing centres. Data collected will
help inform Phase II 2025 drill targets ahead of the next phase of drilling planned for the second
half of 2025.
Summer 2025 Program Highlights
• Exceptional grades in multiple styles of mineralization – Assays up to 45.1 g/t Au, 6.9%
Cu, and 73 g/t Ag from newly identified, structurally hosted quartz vein systems (see
Table 1 and Figure 1)
• Footprint expansion validated by recent sampling and historical data – Integration of
historical values, including up to 371 g/t Ag, 7.7% Pb, and 5.2% Zn, plus 2025 sampling
extends skarn and CRD mineralization along strike (see Figures 2 and 3)
• Targeted sampling delivers new drill targets – 66 rock samples collected from newly
mapped alteration zones generated multiple untested high-grade targets.
• Refined structural model – Updated mapping has improved the understanding of faults
and fractures controlling mineralization.

“The Company’s Summer 2025 field program at Madison has advanced our understanding of the
district’s scale, grade, and structural controls ,” commented Managing Director of Exploration,
Eric Saderholm. “High-grade results, including assays up to 45.1 g/t gold , 6.9% copper, and 73
g/t silver, clearly show the strength of the mineralizing system and its ability to host multiple
styles of mineralization , including skarn, CRD and distal epithermal expressions, with all
indicators pointing to a porphyry source. The integration of new mapping, geochemistry, and
structural analysis with historic al datasets has expanded the mineralized footprint , confirming
continuity and ope ning new exploration corridors and we look forward to the next phase of
drilling during the second half of this year aimed at testing these numerous targets, including
extensions to known skarn and CRD zones and deeper porphyry centres.”

Next Steps:
The Company is incorporating the historical data and 2025 sampling and mapping data into its
3D geological model. Drill target refinement is underway for an H2 2025 program, testing:
• Lateral and at depth skarn/CRD expansion
• Deeper porphyry centers indicated by alteration and geochemical vectors
Madison Project Sampling and Analysis Quality Assurance and Quality Control Statement
American Pacific Mining is committed to high-quality exploration practices at its Madison Project.
