American Pacific Reports up to 80.6 g/t Gold, 5.2% Copper and 136 g/t Silver from the 2024 Field Program at its Madison Project

Vancouver, November 27, 2024 - American Pacific Mining Corp. (CSE: USGD) (FSE: 1QC) (OTCQX: USGDF) ("American Pacific" or the "Company") is pleased to report that it has received the final assays from 88 rock samples and 141 soil samples collected during the 2024 field season. The Company also completed a radiometric survey interpretation to assist future drill targeting for a 3,000-metre, Phase II program scheduled to begin in Q1, 2025.

Field Program Highlights

• A total of 88 rock samples and 141 soil and silt samples were collected during the summer of 2024

• Gold grades of up to 80.6, 38.48 and 19.85 grams per tonne (g/t) were assayed in surface rock samples (see Table 1 and Figure 1)

• Copper grades of up to 5.2% and 3.3% were assayed in surface rock samples (see Table 1 and Figure 2)

• Radiometric surveys highlight thorium, potassium and uranium, which can be porphyry system indicators (see Figure 1 with 2024 gold/silver sample locations)

• The Phase II, 3000-metre drilling program has been finalized and is the permitting process (see Figure 3 for planned hole locations)

Disclaimer: Surface samples, by their nature, are selective and may not represent underlying values.

"We are encouraged by the field work results that followed up on our 2024 drilling program. The field mapping and rock sampling have extended the mineralized footprint 2.5 kilometres southeast and 2 kilometres west. The data collected presents us with 5 additional target areas that have not historically been drill tested but have now been included in the fully-funded Phase II drill program beginning Q1, 2025," commented Managing Director of Exploration, Eric Saderholm. "The higher-grade silver values were unexpected and clearly add to the potential value of the Madison Property. Our use of radiometric surveys is somewhat unique in exploring for porphyry systems and will help us pinpoint drill targets in 2025. Further refinement of the magnetic data will be completed in December to maximize the potential for new property-wide discoveries."

About the Madison Copper-Gold Project

The Madison Project was host to small-scale production that concluded in 2012, with 2.7 million pounds of copper produced at grades ranging from 20-30% copper. Subsequent drilling at Madison in 2017 included 30.18 metres of 24.50 g/t gold and 0.39% copper and 10.97 metres of 41.65 g/t gold and 0.38% copper (UG17-05 and UG17-06, respectively).
