AMERICAN PACIFIC COMPLETES PHASE I DRILL PROGRAM AT MADISON COPPER-GOLD PROJECT IN MONTANA

Drilling has concluded at American Pacific Mining Corp.'s 100-per-cent-owned Madison copper-gold project located in Silver Star, Mon. The first phase of 2025 drilling included a total of eight reverse circulation (RC) drill holes for 1,795 metres testing four priority target areas identified through extensive data integration and analysis. Assay results from the program are expected to be released in July, 2025.

Phase I 2025 drilling focused on porphyry and skarn targets located laterally and down plunge of known mineralization in addition to targets adjacent to the Broadway mine area. A larger second phase of core drilling is planned to test additional porphyry, skarn and regional discovery target areas that were part of a second permit. Successes from the first phase of drilling will also be followed up on as part of H2 2025 (the second half of 2025) drilling.

"Our 2025 drilling has strategically focused on high-impact targets that we believe can deliver substantial value to our shareholders by revealing the true scale of the system beyond previously mined areas," said chief executive officer Warwick Smith. "We look forward to assay results from the RC program and preparing for an exciting follow up campaign that will include further stepout and deeper drilling later this year."

Madison project sampling and analysis quality assurance and quality control statement

American Pacific is committed to maintaining high standards of accuracy and reliability in sampling and analysis procedures. The following quality assurance and quality control (QA/QC) measures are employed in the sampling and analysis processes.

Analytical methods for the project include:

Paragon Labs

• 50AR-MS: multielement analysis (50 elements) using aqua regia digestion with ICP-MS for trace elements;
• AuAg-GR30: gold and silver analysis via 30-gram fire assay with gravimetric finish for high-precision results;
• Au-FA30: gold determination using fire assay with aqua regia digestion and spectroscopy for detailed concentration measurement;
• OLAR-ASS: overlimit aqua regia digestion ensures accurate results for high-concentration samples.

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 to 35 per cent copper. Subsequent drilling at Madison in 2017 included 30.18 metres of 24.50 grams per tonne gold and 0.39 per cent copper and 10.97 metres of 41.65 g/t gold and 0.38 per cent copper (UG17-05 and UG17-06, respectively). Full disclosure can be found in the company's National Instrument 43-101 technical report for the Madison project.
