Drill Results

American Pacific Drills 10.2 g/t Gold over 7.6 Metres Including 44.1 g/t Gold

over 1.5 Metres and Demonstrates Link Between Historic Broadway and

Madison Mine Areas

Vancouver, British Columbia – July 30, 202 5—American Pacific Mining Corp. (CSE: USGD /

OTCQX: USGDF / FWB: 1QC) (“American Pacific” or the “Company”) is pleased to report results

from the final six (6) of eight (8) reverse circulation (“RC”) drill holes completed during Phase I

2025 drilling at the Company’s Madison Project (see press release dated July 10, 2025 for initial

results and Figure 1 for Phase I drill hole locations).

Highlights:

• APMAD25-08 intersected three different mineralized zones, with the upper zone

returning 44.1 g/t Au over 1.5 m within a broader interval averaging 10.2 g/t Au over

7.6 m, starting from 189.2 m downhole. The second zone returned 4.5 g/t Au and 0.2%Cu

over 3.0 m, starting from 230.1 m downhole (see Figure 2).

• APMAD25-08 was a 175 m step-out to the northwest of the historical Broadway Mine

area, with very limited drilling in between, highlighting the expanded exploration search

space and emerging link between the Broadway and Madison mines.

• APMMAD25-05 extended the copper mineralized envelope down plunge towards the

common vector between the Broadway and Madison mines , with 0.5% Cu over 27.4 m

and 0.7 g/t Au over 16.8 m (see Figure 2).

• APMMAD25-06 returned significant pathfinder mineralization, including a notable

interval of 3.0 m averaging 0.23% Bi with 14.5 ppm Te and 4.5 m of 159 ppm Bi with 63

ppm Te

• APMMAD25-07 and 08 returned further porphyry-style geochemical signatures, including

assay values of up to 25.8 ppm Bi with 11.9 ppm Te over 1.5 m

Warwick Smith, CEO of American Pacific, commented: “Our drilling shows a clear link between

the historic Madison and Broadway mines, with the best gold interval from the program

highlighting a tremendous opportunity to extend high er grade skarn mineralization along strike

at shallower depths and vector towards the porphyry feeder system we believe is responsible for

the higher-grade mineralization within the skarn . Our next phase of drilling, set to commence

during H2, will use data collected from Phase I drilling to help refine drill targets as we work

towards delineating what our team believes could be a substantial buried porphyry.”

Eric Saderholm, Managing Director of Exploration, commented : “The Phase I drill results at

Madison validate our current geological model and confirm the historic Broadway and Madison

mines are structurally and stratigraphically linked within a broader mineralized corridor. This is a

revelation that past exploration efforts did not identify. We are very pleased with the strength of

the skarn mineralization encountered and the porphyry -style geochemical signatures. These

include elevated bismuth tellurides and are but one of the lines of evidence that strongly support

the presence of a deeper porphyry system. These mineral assemblages are rare in other geologic

settings and are significant pathfinder minerals associated with porphyry and high -temperature

skarn systems. Their presence supports the interpretation of a ro bust mineralizing system at

depth and provides strong vectors for targeting the potential porphyry center in upcoming drilling

phases.”

Key Observations and Takeaways

The Company’s Phase I 2025 drilling at Madison builds on previous drillin g, reinterpretation of

historical data and comprehensive 3D geological model work to demonstrate a structural and

stratigraphic link between the past-producing Broadway and Madison Mines for the first time in

Project history (see Figure 1 and 2).

The two deposits are located along the same northwest -trending corridor of altered quartz

monzonite and associated skarn (see Figure 1 below) that is now understood to be a part of the

same mineralizing system. Historical mining at Broadway extracted gold grades averaging 9.9 g/t

Au for 144,000 ounces (1870-1942)1 hosted in the contact aureole . Geological continuity has

been established between the two mines, expanding the exploration search space and indicating

that mineralization extends well beyond the mining limits of both historically mined areas. Strong

west, northwest and southwest vectors have emerged , which have not been historically

interpreted or tested.

Note: Intercepts encountered in drill holes 01, 02, 07, and 08 demonstrate strong continuity of mineralization between the hi storical Broadway

Mine horizon and plunge of mineralization at Madison, supporting the presence of a shared mineralizing fluid pathway that remains open at

depth.

Phase I results from the Project have confirmed additional skarn mineralization alongside strong

geological indicators consistent with a deeper porphyry system, including alteration

assemblages, mineral zoning, and geochemical signatures. These findings reinforce the

Company’s interpretation of a larger mineralized system at depth, with structurally controlled

pathways offering critical vectors for targeting. The data has significantly refined future drill

planning and prioritized the most prospective zones for deeper porphyry-focused exploration.

Historic Material Provides Additional Value Potential

Select holes (03, 04) were located to test areas of historic material from past mining operations

at the Project. APMMAD25-03 returned 0.7 g/t Au, 20.8 g/t Ag and 0.3% Cu over 10.7 m from

surface, confirming that a substantial portion of the material retains strongly anomalous metal

values. Additional grab samples of stockpiled material (9 total samples) ranged from 0.84 to

45.4 g/t Au, 21.3 to 100 g/t Ag and 0.85 to 8.33 % Cu, further demonstrating the potential for

material previously considered waste to provide a cash flow opportunity in the future.
