NEWS RELEASE

American Pacific Mining Prepares to Commence Drill Program

at the Madison Copper-Gold Project

Vancouver, British Columbia / September 13, 2023 - American Pacific Mining Corp (CSE:

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

to report that a five (5) hole diamond drill campaign is set to commence in early Q4/2023 at the

Madison Copper-Gold Project (“Madison” or the “Project”) located in Madison County,

Montana.

The drill program is designed to further define near -surface, high- grade copper and gold

mineralization and provide a foundation for deeper exploration in areas with limited historical

drilling. In part, this 2023 program will follow up on the last partner funded campaign, which

included an intersection of 14.44 grams per tonne (“ g/t”) gold (“Au”) over 6.53 metres (“m”)

(see January 12, 2022 news release). Drill holes have been strategically placed to accomplish

multiple objectives and test numerous targets with each hole. The program aims to accomplish

three key objectives: test shallow gap areas; tighten drill spacing at moderate depth within the

skarn to support future mineral resource estimation; and extend below known mineralization to

provide valuable information for deeper exploration in subsequent campaigns (see Figure 1

and 2).

“We are excited to begin drilling at Madison and view this drilling campaign as an opportunity

to make an already strongly mineralized system more robust , while collecting valuable

information in untested areas ,” commented Warwick Smith, CEO of American Pacific. “The

ultimate prize at Madison is the potential for a deep-rooted porphyry deposit, but we believe the

shallow high-grade skarn mineralization will be an important contributor during the early years

of any future mining scenario at Madison and believe it can expand significantly with further

exploration work.”

Kennecott Exploration Company (“KEX”), a division of the Rio Tinto Group, has spent

approximately US$6.8M at the Madison Copper -Gold Project and may earn up to 70% of the

Project by spending US$30M by 2030. The focused Q4/2023 five -hole program (3,700 feet /

1,130 metres) does not incorporate multiple planned deeper drill holes that will be considered

as part of 2024 drilling to test the porphyry potential at depth. American Pacific will be leading

the exploration for the 2023 drill campaign with the support of KEX. The drill program is in

process of being permitted and field work will commence once all permits are granted.

Technical Summary

The Property has distinctive mineralization types throughout the P roperty. The stronger

mineralization can be found in oxidized jasperoid, classic high-iron skarn, massive sulfide and

gold/silver-rich quartz veining with typical high-level signatures and textures. Lower grade gold

mineralization locally occurs in endoskarns within the proximal granodiorite intrusive rock. All

of these mineralization suites are interpreted to be associated with the emplacement of

numerous igneous intrusion episodes emplaced during the late Cretaceous to early Tertiary

geologic periods . Min eralization styles and tenor are dependent on the rocks hosting the

mineralization. The jasperoid mineralization is high level and is generally found in the dolomitic

rock of the Devonian Jefferson Formation. The skarn mineralization, including the massive

sulfide, can be both gold and/or copper-rich and occurs within the highly reactive limestone and

shale units within the greater Madison Group of Mississippian age. The quartz vein

mineralization is generally found within older Precambrian metasediments. The nature and

genesis of the quartz vein mineralization is currently poorly understood and has not been

sufficiently tested.
