NEWS RELEASE

AMERICAN PACIFIC ANNOUNCES REGIONAL EXPLORATION DRILLING TO BUILD ON

SUCCESSFUL 2023 FIELD SEASON AT THE PALMER VMS PROJECT

Vancouver, British Columbia / October 4, 2023 - American Pacific Mining Corp (CSE:

USGD / OTCQX: USGDF / FWB: 1QC) (“American Pacific” or the “Company”) is pleased

to announce that one drill rig has remained to test the Christmas/Red Creek (“ CRC”) Target

area during demobilization of the 2023 mountain drilling program. The CRC Target is one of 12

known VMS showings at the Palmer Project (“ Palmer” or the “Project”) outside the mineral

resource envelopes of the Palmer and AG deposits (see Figure 1).

Palmer is an advanced- stage, high- grade volcanogenic massive sulphide- sulphate deposit

(“VMS”) located in the Porcupine Mining District of the Haines Borough, Alaska, US .

Constantine North Inc. (“Constantine”), a subsidiary of American Pacific, is the operator for the

Project and the US$25.5 million 2023 program has been funded by joint venture partner Dowa

Metals & Mining Co., Ltd (“Dowa”).

“The regional exploration upside and potential for additional discoveries is considered excellent

at Palmer, and we are pleased to incorporate this initial ~500 metres before the end of this

year’s drill campaign,” stated Warwick Smith, CEO 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 de-risk and expand mineral resources at Palmer going forward.”

The CRC Target area is located approximately 3 kilometres (“km”) east of the Palmer deposit

(see Figure 1). 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 (1-2) road-accessible drillholes 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 d eposit resource area has

concluded. The Company expects to report initial assay results shortly, along with a full

summary of the 2023 program accomplishments.
