American Pacific Samples up to 45.1 g/t Gold, 6.9% Copper and Significantly Expands Mineralized Footprint at Madison
American Pacific Mining (OTCQX: USGDF) has announced significant results from its Summer 2025 surface sampling program at the Madison Copper-Gold Project in Montana. The program revealed exceptional grades including up to 45.1 g/t gold, 6.9% copper, and 73 g/t silver from newly identified quartz vein systems.
The mineralized footprint has been expanded to a 4-kilometer by 2-kilometer area, with multiple styles of mineralization including skarn, CRD, and distal epithermal expressions. The company collected 66 rock samples from newly mapped alteration zones, generating multiple untested high-grade targets. Integration of historical values, including samples with up to 371 g/t silver, 7.7% lead, and 5.2% zinc, has extended known mineralization along strike.
The company plans to proceed with Phase II drilling in the second half of 2025, targeting both shallow and deep-seated mineralizing centres.
American Pacific Mining (OTCQX: USGDF) ha annunciato risultati significativi dal programma di campionamento superficiale dell'estate 2025 presso il Madison Copper-Gold Project in Montana. Il programma ha rivelato grade eccezionali, fino a 45,1 g/t d'oro, 6,9% di rame e 73 g/t d'argento provenienti da nuovi sistemi di vene quarzose identificati.
L'impronta mineralizzata si è ampliata a un'area di 4 chilometri per 2 chilometri, con molteplici stili di mineralizzazione, inclusi skarn, CRD e manifestazioni epiterimali distali. La società ha raccolto 66 campioni di roccia da zone di alterazione appena mappate, generando numerosi target ad alto tenore ancora non testati. L'integrazione dei valori storici, compresi campioni con fino a 371 g/t d'argento, 7,7% di piombo e 5,2% di zinco, ha esteso la mineralizzazione nota lungo lo strike.
La società prevede di procedere con la perforazione di Fase II nella seconda metà del 2025, mirando a centri mineralizzanti sia superficiali che profondi.

- Exceptional high-grade samples with up to 45.1 g/t gold and 6.9% copper discovered
- Significant expansion of mineralized footprint to 4km x 2km area
- Multiple new untested high-grade targets identified from 66 rock samples
- Multiple styles of mineralization confirmed, indicating large-scale potential

Vancouver, British Columbia--(Newsfile Corp. - September 4, 2025) - American Pacific Mining Corp. (CSE: USGD) (OTCQX: USGDF) (FSE: 1QC1) ("American Pacific" or the "Company") is pleased to announce the successful completion of its Summer 2025 surface sampling field program at the Madison Copper-Gold Project (the "Project") in Montana, USA.
Results confirm the presence of additional high-grade skarn-style mineralization at surface, along with polymetallic and porphyry-style indicators across the district, which has now been expanded to a 4-kilometre by 2-kilometre footprint. These findings strengthen the case for Madison as a large, fertile hydrothermal system hosting multiple mineralization styles, with near-term drill targets aimed at both shallow and deep-seated mineralizing centres. Data collected will help inform Phase II 2025 drill targets ahead of the next phase of drilling planned for the second half of 2025.
Summer 2025 Program Highlights
Exceptional grades in multiple styles of mineralization - Assays up to 45.1 g/t Au,
6.9% Cu, and 73 g/t Ag from newly identified, structurally hosted quartz vein systems (see Table 1 and Figure 1)Footprint expansion validated by recent sampling and historical data - Integration of historical values, including up to 371 g/t Ag,
7.7% Pb, and5.2% Zn, plus 2025 sampling extends skarn and CRD mineralization along strike (see Figures 2 and 3)Targeted sampling delivers new drill targets - 66 rock samples collected from newly mapped alteration zones generated multiple untested high-grade targets.
Refined structural model - Updated mapping has improved the understanding of faults and fractures controlling mineralization.
