Mining Stock Daily American Pacific Mining Begins 10,000-Meter Drill Program to Unlock Madison
Mar 18, 2026
Eric Saderholm, Managing Director of Exploration at American Pacific Mining, leads technical programs at the Madison copper-gold project. He discusses a 10,000-meter drill campaign targeting deep porphyry systems and near-surface skarn. Advanced tools like 3D‑MT, AI-driven geochemistry, UV calcite mapping, and strategic pad placement shape the search for the source of high-grade mineralization.

Episode notes
Skarn Points To A Deeper Porphyry Source
- American Pacific focused beyond the mined skarn to locate the deeper porphyry source driving high-grade copper and gold at Madison.
- Geochemical patterns (tellurium, molybdenum, bismuth) and AI analysis revealed separate but adjacent gold and copper plumbing systems guiding target vectors.
AI And Geochemistry Revealed Dual Plumbing Systems
- The team used AI on extensive local geochemical data to map distinct gold and copper systems along the plumbing network.
- Presence of tellurium, molybdenum and bismuth acted as porphyry pathfinders indicating flank positions.
Linking Madison And Broadway Validated The Plumbing
- By physically connecting Madison and Broadway underground they proved both were fed by the same plumbing but with different mineral pulses.
- Old pre-mining maps from Montana Tech were incorporated to validate the linked systems.
