American Pacific Mining Prepares to Drill High-Priority Porphyry and Skarn Targets at Madison Copper-Gold Project

Executive Summary

• American Pacific Mining Corp. announced Phase II drill targets for its 100% owned Madison Copper‑Gold Project in Montana, following receipt of a key drill permit.
• The program will test large‑scale porphyry and high‑grade skarn targets using step‑out and deeper holes guided by extensive geological work, IP chargeability highs, and magnetic anomalies.
• Historical drilling has intersected exceptionally high grades (e.g., 30.18 m @ 24.50 g/t Au & 0.39% Cu; 10.97 m @ 41.65 g/t Au & 0.38% Cu), and the new phase aims to expand these zones and evaluate district‑scale potential.

Key Details

• Permit Status: Drill permit received in early October 2025, enabling commencement of Phase II drilling.
• Target Focus – Porphyry System:
• Holes will probe beneath previously intersected copper‑gold skarn zones to test IP chargeability highs and magnetic boundaries interpreted as the top of a concealed porphyry center.
• Target Focus – High‑Grade Skarn Expansion:
• Step‑out holes along the Silver Star structural corridor aim to extend known high‑grade skarn mineralization (historical intercepts: 30.18 m @ 24.50 g/t Au & 0.39% Cu; 10.97 m @ 41.65 g/t Au & 0.38% Cu).
• Program will test down‑dip and along‑strike extensions at lithologic contacts between Madison Group limestone and Rader Creek intrusions.
• Untested Structural Targets:
• Shallow holes to evaluate surface alteration, veins, and copper‑oxide staining along structural pathways as potential feeders linking upper‑level skarn/vein mineralization to deeper intrusive sources.
• District‑Scale Potential:
• Multiple magnetic and geochemical anomalies identified across the district; a newly mapped mafic intrusion returned grab sample assays up to 38.5 g/t Au and 33 g/t Ag, to be tested with shallow reconnaissance holes.
• Historical Production Context:
• Madison Project hosted small‑scale production ending in 2012 (2.7 M lbs Cu at 20–35% Cu).
• Prior drilling (2017) intersected high‑grade gold‑copper skarn zones as noted above.
• Technical Documentation: Full disclosure available in the company’s NI 43‑101 Technical Report for Madison (link provided).

Notable Quotes

“As our geologic team has continued to generate, compile, and model data, the source of Madison's high‑grade skarns and veins is becoming much clearer,” – Eric Saderholm, Managing Director of Exploration.
“Today, we have a much more precise understanding of the source of those high‑grade zones and Phase II drilling will focus on these newly identified targets as we work to demonstrate Madison's full potential.” – Eric Saderholm.
