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

(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - July 30, 2025) - American Pacific Mining Corp. (CSE: USGD) (OTCQX: USGDF) (FSE: 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 higher 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 robust 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 drilling, 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 historical 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.
