American Pacific Samples up to 45.1 g/t Gold, 6.9% Copper and Significantly Expands Mineralized Footprint at Madison

Executive Summary

• American Pacific Mining Corp. announced the successful completion of its Summer 2025 surface sampling program at the Madison Copper-Gold Project in Montana, USA.
• The program identified additional high-grade skarn-style mineralization and polymetallic/porphyry indicators, expanding the project's known footprint to 4km by 2km.
• Results have generated new, untested high-grade drill targets for Phase II drilling planned for the second half of 2025, focusing on shallow and deep-seated mineralizing centers.

Key Details

• Program Scope: Summer 2025 surface sampling field program at the Madison Copper-Gold Project.
• Footprint Expansion: The mineralized district footprint has been expanded to 4 kilometers by 2 kilometers.
• New Mineralization Styles: Confirmation of high-grade skarn-style mineralization, polymetallic indicators, and porphyry-style indicators, suggesting a large, fertile hydrothermal system.
• Key Assay Results (Summer 2025):
  • Up to 45.1 g/t Au, 6.9% Cu, and 73 g/t Ag from newly identified, structurally hosted quartz vein systems.
  • Sample zh25055 returned 45.1 g/t Au, 6.9% Cu, and 73 g/t Ag.
  • Sample zh25013 returned 11.6 g/t Au and 1.1% Cu.
  • Sample zh25014 returned 2.3% Cu, 1.4% Pb, and 17.1% Zn.
• Historical Data Integration:
  • Historical values integrated include up to 371 g/t Ag, 7.7% Pb, and 5.2% Zn.
  • Notable historical samples reported in the release include:
    • MAD24KM-044: 80.6 g/t Au and 77.7 g/t Ag.
    • ZH003: 41.3 g/t Au and 136.0 g/t Ag.
    • MAD24KM-045: 38.5 g/t Au and 33.0 g/t Ag.
    • MAD24KM-009: 13.6 g/t Au and 85.6 g/t Ag.
• Drill Targets: 66 rock samples from newly mapped alteration zones generated multiple untested high-grade targets.
• Next Steps (H2 2025):
  • Incorporating historical and 2025 data into a 3D geological model.
  • Drilling will test lateral and at-depth skarn/CRD expansions.
  • Drilling will test deeper porphyry centers indicated by alteration and geochemical vectors.
• QA/QC: Samples analyzed at Paragon Geochemical Laboratories (Sparks, NV) using methods including 50AR-MS (Aqua Regia/ICP-MS), Au-GR30 (Fire Assay/Gravimetric), Au-FA30 (Fire Assay/Aqua Regia), and OLAR-ASS (Over-limit Aqua Regia).

Notable Quotes

• "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."
