American Pacific Identifies New Geological Anomalies Revealed in Underground Workings in Advance of Drill Program at Madison Copper-Gold Project in Montana

Executive Summary

• American Pacific Mining Corp. announced the successful application of a “fugitive calcite” black‑light scanning technique at its Madison Copper‑Gold Project in Montana.
• The method identified fluorescing calcite veins that provide new structural data to refine vectors toward porphyry and carbonite replacement deposit targets, supporting the hypothesis of multiple porphyry sources.
• Management indicated further updates will follow as additional underground data are collected and integrated into the project model.

Key Details

• Technique Deployed: Ultraviolet (black‑light) scanning to detect “fugitive calcite,” a method learned from Dr. Peter Megaw.
• Field Conditions: A short seasonal window of lower water levels exposed an additional 150 ft of underground ramp access, enabling the work.
• Results: At least one distinct population of fluorescing veins was identified; these veins contain trace Mn and Pb, indicators of carbonate replacement associated with skarn, CRD, and distal porphyry mineralization.
• Interpretation Value: When plotted on stereonets, the fluorescing vein data add a new structural layer that can help refine exploration vectors toward both porphyry and carbonite replacement deposit targets.
• Exploration Hypothesis Impact: Supports the view that Madison may host a cluster of porphyries rather than a single centralized system.
• Management Quote: Eric Saderholm, Managing Director of Exploration, highlighted the technique’s low cost and effectiveness for detecting mineralization‑related calcite.
• Future Plans: American Pacific will continue data collection, interpretation, and integration into the broader Madison exploration model, with further updates to be provided.

Notable Quotes

“The fluorescence in the calcite indicates the presence of trace amounts of manganese and lead… Fugitive calcite represents ‘exhaust’ proximal to where sulfide mineralization has formed containing stronger metal concentrations. It is a simple and inexpensive, yet highly effective tool for this type of mineral exploration.” – Eric Saderholm, Managing Director of Exploration

Materiality Assessment: Non‑Material – Positive (the update provides technical insight but does not constitute a material change to the company’s financial or operational outlook).
