Core Insights - American Pacific Mining Corp. has announced Phase II drill targets at its 100%-owned Madison Copper-Gold Project, located in the Idaho-Montana Porphyry Belt, southeast of Butte, Montana [1][2] Drilling Plans - The company has received a key drill permit and will focus on large-scale porphyry and high-grade skarn targets, utilizing decades of geological data [2] - The highest-priority holes will target beneath previously intersected copper-gold skarn zones, aiming to identify a concealed porphyry copper-gold center [3] Geological Understanding - The exploration team has improved its understanding of the source of high-grade skarns and veins at Madison, which were not well defined two years ago [4] - The upcoming drilling will focus on newly identified targets to demonstrate the full potential of the Madison Project [4] High-Grade Mineralization - Step-out holes will aim to expand known high-grade copper-gold skarn mineralization, with historical intercepts showing significant grades, including 30.18 meters of 24.50 grams per tonne gold and 0.39% copper [7] - The program will test extensions where skarn alteration remains open, particularly at lithologic contacts [7] New Structural Targets - Several new areas have been included in the drilling plan, defined by strong alteration and copper-oxide staining at the surface [8] - Shallow holes will evaluate these features as potential conduits linking upper-level skarn and vein mineralization to deeper sources [8] District-Scale Potential - The geological team has identified multiple magnetic and geochemical anomalies across the district, with one mafic intrusion returning assays of up to 38.5 g/t gold and 33 g/t silver [9] - These anomalies will be tested with shallow reconnaissance holes to assess the scale and continuity of the mineralized system [9] Project Background - The Madison Project previously produced 2.7 million pounds of copper at high grades, with significant historical drilling results [10] - Additional production from nearby mines has demonstrated a structural link to the Madison Project, indicating a broader mineralizing system [11] Company Overview - American Pacific Mining Corp. focuses on precious and base metals exploration in the Western United States, with flagship assets including the Palmer Project in Alaska and the Madison Project in Montana [12] - The company aims to grow through exploration and acquisition, having been recognized for its achievements in the mining sector [12]
