American Pacific preps for phase 2 drilling at Madison

USGD · Price
Executive Summary
- American Pacific Mining Corp. has secured a key drill permit and is commencing Phase II drilling at its wholly‑owned Madison copper‑gold project in Montana.
- The upcoming program will target high‑priority porphyry and skarn zones, including stepout holes along the Silver Star corridor and shallow reconnaissance holes on newly identified structural targets.
- Historical underground intercepts (e.g., 30.18 m @ 24.50 g/t Au & 0.39% Cu) underscore the project's high‑grade potential, supporting the company’s strategy to “grow by the drill bit.”
Key Details
- Permit Acquisition: Received a key drill permit in early October, enabling Phase II drilling activities.
- Drill Target Focus:
- Porphyry targets: Deep holes will test IP chargeability highs and magnetic boundaries interpreted as the top of a concealed porphyry copper‑gold centre.
- Skarn expansion: Stepout holes along the Silver Star structural corridor aim to extend known high‑grade zones (historical intercepts: 30.18 m @ 24.50 g/t Au, 0.39% Cu; 10.97 m @ 41.65 g/t Au, 0.38% Cu).
- New Structural Targets: Shallow holes will evaluate surface alteration, veins, and copper‑oxide staining as potential feeders linking upper‑level skarn/vein mineralization to deeper intrusive sources.
- District‑Scale Exploration: Recent mapping identified a mafic intrusion with grab sample assays up to 38.5 g/t Au and 33 g/t Ag; shallow reconnaissance drilling will test the continuity of this anomaly.
- Historical Production Context: Madison produced 2.7 M lbs Cu (20–35% Cu) before ceasing operations in 2012; additional nearby production includes ~147,000 oz Au at 9.9 g/t.
- Management Commentary: Eric Saderholm, Managing Director of Exploration, highlighted the improved geological understanding and the significance of Phase II drilling to demonstrate Madison’s full potential.
Notable Quotes
“This is truly an exciting time for American Pacific… 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, Managing Director of Exploration.
