Vancouver, British Columbia--(Newsfile Corp. - June 1, 2026) - American Pacific Mining Corp. (CSE: USGD) (OTCQX: USGDF) (FSE: 1QC) (WKN: A422L8) is pleased to announce that it has commenced a 15,000-metre drill program combining both reverse circulation (" RC ") and diamond core drilling at its Madison Copper-Gold Project (" Madison " or the " Project ") in Montana.

The drilling campaign will concentrate on shallow skarn mineralization for 10,000 metres and deeper porphyry mineralization for an additional 5,000 metres. Five top-ranked skarn and porphyry targets have been selected for drilling, representing the most well-defined targets to date, identified through comprehensive technical evaluation and analysis.

RC drilling will be used primarily for rapid and cost-effective testing of near-surface skarn targets, while diamond drilling will focus on deeper targets where the Company believes there is potential for porphyry-related mineralization beneath and adjacent to the known skarn system. The staged RC and core approach is designed to provide steady operational progress while allowing near-surface target testing to advance alongside deeper system-scale exploration.

"We're thrilled to have drilling underway at Madison, where we're now methodically testing the highest-quality skarn and porphyry targets ever identified at the Project," commented CEO and Director, Warwick Smith. "These targets are the product of rigorous data integration, meticulous analysis of both legacy and contemporary information, and advanced 3D geological modelling. We're excited to see drilling results enhance and validate our current geological interpretation of the Project."

The Company believes the current program represents an important step toward advancing Madison as a high-grade copper-gold exploration and development opportunity. The near-surface portion of the program is intended to test extensions of known skarn mineralization and refine targets that could support future resource definition work, while the deeper diamond drilling component is designed to evaluate the potential for a broader porphyry-related source system.

Initial assay results are anticipated this summer. The Company will provide further updates as drilling progresses.
