Vancouver, British Columbia--(Newsfile Corp. - March 31, 2025) - American Pacific Mining Corp. (CSE: USGD) (OTCQX: USGDF) (FWB: 1QC1) ("American Pacific" or the "Company") is pleased to report that it has received updated permit approval corresponding to a focused 3,000 metre drill program at its Madison Copper-Gold project located in Silver Star, Montana, which is expected to commence in early Q2/2025. The drill program will test two porphyry targets, multiple skarn extensions and high-grade fault systems (see Figures 1-4).

The Madison Project ("Madison" or the "Project") has undergone a transformative process of review and integration, consolidating decades of exploration data, historical drilling records, geophysical and geochemical surveys, and field mapping efforts, and revealed five priority target areas, providing the foundation for a district-wide exploration strategy aimed at uncovering the full mineral potential of the Project.

"Following an intensive exploration campaign throughout 2024, we meticulously analyzed and validated a wealth of newly identified targets and substantiated the Project's potential for diverse mineralization styles, including skarn-hosted deposits, orogenic gold veins, porphyry-style systems and carbonate replacement mineralization," commented Eric Saderholm, P.Geo., Managing Director of Exploration and Qualified Person for the project. "This next phase of drilling will include near-mine extension drilling at the Broadway mine area, while also testing highly prospective porphyry concepts and regional discovery targets. We believe we are taking the most informed discovery shots drilled to-date at the Project."

The program is expected to demonstrate significant potential across the Madison district, advancing the Company's vision of uncovering a copper-gold system of meaningful scale.

Silverstar Fault Complex - Unlocking Exploration Upside

Central to the Company's exploration strategy is the Silverstar Fault Complex, a significant structural feature that underpins the district-wide drilling program. This fault complex has emerged as a critical control on mineralization, offering insights into the architecture of the Madison Project. Induced Polarization (IP) surveys have revealed compelling geophysical anomalies along the fault system, identifying highly prospective zones of chargeability and resistivity.

The upcoming drill campaign will strategically target these high-priority zones, leveraging the Silverstar Fault Complex as a structural guide to test for skarn, porphyry, and orogenic mineralization in undrilled areas.

About the Madison Copper-Gold Project

The Madison Project was host to small-scale production that concluded in 2012, with 2.7 million pounds of copper produced at grades ranging from 20-35% copper. Subsequent drilling at Madison in 2017 included 30.18 metres of 24.50 g/t gold and 0.39% copper and 10.97 metres of 41.65 g/t gold and 0.38% copper (UG17-05 and UG17-06, respectively).
