American Pacific Mobilizes Drill Rig to

Madison Copper-Gold Project in Montana

Vancouver, British Columbia / May 28, 2024 – American Pacific Mining Corp . (CSE: USGD / OTCQX:

USGDF / FWB: 1QC) (“American Pacific” or the “Company”) is pleased to announce that it has mobilized

a drill to its Madison Copper-Gold Project (“Madison” or the “Project”) in Montana, in preparation for an

initial CAD $1.5 million, five-hole, 1,350 metre drill program.

Drilling will focus both on the near-mine area to extend the known mineralized zone identified through

historical drilling, which included intercepts of 14.69 metres (“m”) of 12.10 grams per tonne (“g/t”) gold

(“Au”) and further downhole 61.63 m of 6.97% copper (“Cu”). The Company also plans to test highly

prospective areas, identified through the interpretation of extensive historical and recent data, that have

never been drilled.

Phase II will focus on following up on positive results from Phase I drilling, while also testing deeper

regional targets within the western portion of the Project. This region has recorded historical, gold values

at surface of up to 48.5 g/t Au in undrilled locations , which the Company believes could suggest the

presence of a concealed intrusive heat source.

"We are pleased to be mobilizing a drill rig to Madison in preparation for drilling. Phase I will focus on

areas where exceptional copper and gold mineralization have been encountered historically," commented

CEO & Director, Warwick Smith. "By drilling the near-mine area, we aim to confirm and expand upon this

high-grade zone to build towards a first mineral resource estimate at the Project. As part of Phase II, our

technical team has identified several highly prospective, yet untested, regional targets that we believe

may represent the peripheral expression of a larger mineralized system. The upcoming drill program will

be an opportunity for us to evaluate the exploration upside potential of these priority target areas. And,

with a robust treasury, we are in an excellent position to embark on this multi-phase drill campaign as we

aim to unlock the full value of the Madison Copper-Gold Project."

The phase one drill program is expected to take four to five weeks to complete. With assay results

anticipated to be released during Q3 2024.

Corporate Update

The Company also reports that Centerra Gold Inc. has terminated the Option Agreement that provided an

opportunity to earn 70% of the Ziggurat Project.
