Using Reverse Circulation Adapted from Information by American Pacific Mining Corp. (American Pacific) American Pacific announced the arrival of a second drill rig at its fully owned Madison CopperGold Project in Montana, which has begun drilling to evaluate near-surface skarn (coarse-grained calc-silicate rock) targets. The reverse circulation (RC) drill rig is part of a comprehensive, fully funded 49,000-foot program that also includes diamond core drilling. The 2026 drilling initiative at Madison aims to thoroughly investigate both near-surface skarn targets and deeper porphyry-style mineralization, which management believes could support a substantial copper-gold system. The RC drill will concentrate on efficiently assessing a range of near-surface skarn targets exhibiting geological traits similar to the historic Madison and Broadway Mine area, known for their high-grade copper and gold output. This exploration is intended to build upon previous efforts and seeks to uncover additional shallow, potentially high-grade mineralization. Achieving success in this phase may highlight the potential for expanding the known mineralized area surrounding the existing skarn system. The approach of combining RC and core drilling is designed to advance near-surface target testing alongside broader system-scale exploration, offering investors exposure to both potential shallow mineralization and the larger porphyry-style prospects within the same drilling program. “With RC drilling now underway to test multiple near-surface skarn targets and the core rig already stepping into the deeper porphyry environment, we are now in a position to generate steady results through the summer and, we hope, demonstrate the true scale of this system,” stated Managing Director of Exploration, Eric Saderholm. “If we are successful in extending the known mineralization and vectoring into a larger copper-gold system, we believe Madison has the potential to become a cornerstone asset that can drive meaningful value for our shareholders.” O’Keefe Drilling testing the first RC hole (Hole ID M26RC-01). Anatomy of a CME Solid Flight Auger Adapted from Information by Central Mine Equipment (CME) Every CME continuous flight auger starts with quality U.S. steel and is produced in their St. Louis factory. The company uses a one-piece heat-treated auger tube with an upset forged hex box connection. The forged box allows for a smaller diameter auger tube which reduces overall weight and increases area for cuttings to move along the flights. The anatomy of a solid flight auger includes: j Drive pins are heat-treated forgings for long wear life and spring retention. j Hex pin coupling is welded to the top of the auger tube. j Flighting width and pitch are specific to the auger diameter for efficient cleaning of the hole. It’s welded to the auger tube and is hard surfaced on the outer edge for greater wear life. j Auger diameter is designed to convey cuttings, not create the hole. Therefore, it will always be slightly smaller than its corresponding auger cutting head. j Hard surfaced flighting for greater wear life. j Pin and box connections are "timed" for consistent alignment between auger sections. CME has been providing continuous flight auger tools since 1928. 7 AUGUST 2026 E-News Flash by WorldWide Drilling Resource by WorldWide Drilling Resource®
