AMERICAN PACIFIC ANNOUNCES REGIONAL EXPLORATION DRILLING TO BUILD ON SUCCESSFUL 2023 FIELD SEASON AT THE PALMER VMS PROJECT

One drill rig has remained to test the Christmas/Red Creek (CRC) target area during demobilization of American Pacific Mining Corp.'s 2023 mountain drilling program. The CRC target is one of 12 known volcanogenic massive sulphide showings at the Palmer project outside the mineral resource envelopes of the Palmer and AG deposits.

Palmer is an advanced-stage, high-grade volcanogenic massive sulphide-sulphate deposit (VMS) located in the Porcupine mining district of the Haines borough, Alaska, United States. Constantine North Inc., a subsidiary of American Pacific, is the operator for the project and the $25.5-million (U.S.) 2023 program has been financed by joint venture partner Dowa Metals & Mining Co. Ltd.

"The regional exploration upside and potential for additional discoveries is considered excellent at Palmer, and we are pleased to incorporate this initial approximately 500 metres before the end of this year's drill campaign," stated Warwick Smith, chief executive officer of American Pacific Mining. "We are pleased to be drilling new targets during the 2023 program that are outside of the known mineralized zones. During the season our technical team also completed mapping and sampling of numerous exploration targets and we look forward to more discovery-focused drilling as we aim to both derisk and expand mineral resources at Palmer going forward."

The CRC target area is located approximately three kilometres east of the Palmer deposit. Stratigraphy at CRC is interpreted as a folded mafic and felsic volcanic sequence, with textural, geochemical and alteration characteristics that are similar to the felsic volcanics that host the AG deposit. Completing one to two road-accessible drill holes will provide valuable data in this area, which has had limited exploration work previously.

American Pacific considers 2023 to be an outstanding year for Palmer. The technical team continuously progressed the project from exploration toward advanced evaluation. The productive 2023 infill and geotechnical drilling at the Palmer deposit resource area has concluded. The company expects to report initial assay results shortly, along with a full summary of the 2023 program accomplishments.
