AMERICAN PACIFIC COMPLETES ITS 2024 DRILL PROGRAM AT PALMER COPPER-ZINC VMS PROJECT IN SOUTHEAST ALASKA

American Pacific Mining Corp. has completed a drill program at its Palmer copper-zinc VMS (volcanogenic massive sulphide) project in southeastern Alaska. The 2024 program was part of a planned $17.5-million ($12.8-million (U.S.)) exploration and development budget financed by a joint venture partnership between Dowa Metals & Mining Alaska Ltd. and American Pacific (see March 25, 2024, news release).

Palmer project update

The 2024 drill program included a total of 6,035.9 metres (19,650 feet) in 19 drill holes, including three drill holes (125.8 metres; 410 feet) that were recollared. The program was expanded from an originally planned 14 drill holes based on positive visual observations and real-time modelling updates.

This year's drilling program focused on building upon the results of last year's campaign, where the four most significant copper intercepts ever drilled at Palmer were reported earlier this year, including 43.8 metres of 6.54 per cent copper, 3.15 per cent zinc, 0.42 gram per tonne gold and 27.97 grams per tonne silver (8.22 per cent copper equivalent) (see Jan. 10, 2024, news release for full details).

The drill program was designed to continue expanding the known extent of the high-grade copper mineralization of the South Wall zone 1 and zone 2 and testing prospective alteration areas. Thirteen drill holes (4,876.8 metres; 16,000 feet) tested the structural controls and extensions to the high-grade copper-mineralized and zinc-mineralized trends.

The program also included a series of exploration drill holes to test the nearby North Wall target. The North Wall target represents a potential fault offset extension of the South Wall mineralization. Three drill holes were completed for 1,033.3 metres (3,390 feet).

A total of 1,353 samples have been submitted for multielement analysis, with all assay results pending.

"We are delighted to have completed another successful exploration program with zero incidents or injuries throughout the summer. We look forward to publishing results in the coming weeks and months," commented Peter Mercer, senior vice-president of advanced projects. "We'd like to thank our staff and contractors for their outstanding efforts in delivering a safe and efficient field program, ahead of schedule. We have seen significant improvements in diamond drilling productivity year over year, which will have a significant impact on the planning and implementation of future programs."

American Pacific Mining is a precious metal and base metal explorer and developer focused on opportunities in the Western United States. The company has two flagship assets: the Palmer project, a volcanic massive sulphide-sulphate (VMS) project in Alaska, under joint venture partnership with Dowa Metals & Mining, owner of Japan's largest zinc smelter; and the Madison project, a past-producing copper-gold project in Montana. For the Madison transaction, American Pacific was selected as a finalist in both 2021 and 2022 for Deal of the Year at the S&P Global Platts Metals Awards, an annual program that recognizes exemplary accomplishments in 16 performance categories.

Also, in American Pacific's asset portfolio are high-grade precious metal projects located in key mining districts in Nevada, United States, including the Ziggurat gold project and the Tuscarora gold-silver district. The company's mission is to grow by the drill bit, strategic partnerships, and M&A (mergers and acquisitions).
