AMERICAN PACIFIC MINING PROVIDES PROGRESS UPDATE FOR PHASE I DRILL PROGRAM AT MADISON COPPER-GOLD PROJECT IN MONTANA

American Pacific Mining Corp. has provided an update on the company's 15,000-metre drill program at its Madison copper-gold project near Silver Star, Mon.

A total of 2,048 metres has been completed to date, of which 1,620 metres are core holes targeting the porphyry and 428 metres are reverse circulation (RC) targeting the near-surface skarn expressions and high-grade vein zones. Initial results from assays are expected to be published in the coming weeks, after which a further 5,000 metres of drilling is expected to be reported as part of the phase I drill program.

"We are pleased with the progress of the phase I drill program at Madison and are encouraged by what we are seeing in the rocks thus far," commented Eric Saderholm, managing director of exploration. "This phase I program is testing the majority of our regional targets which are located distal to the known mines in untested areas. Phase II will focus on drilling in areas that return favourable results from this initial 2026 drilling program."

The phase II drill program at Madison will commence after evaluation of the phase I results and is expected to include up to 7,500 metres of additional drilling beginning in fall 2026.
