American Pacific Announces New Geological Discoveries and Target Vectoring in Preparation for Drill Program at Madison Copper-Gold Project in Montana

American Pacific Mining Corp. (CSE: USGD,OTC:USGDF) (OTCQX: USGDF) (FSE: 1QC1) ("American Pacific", or the "Company") is pleased to announce a new geological observation from ongoing work at its Madison Copper-Gold Project ("Madison" or the "Project") in Montana. This development stems from detailed underground mapping, sampling and technical evaluation, which have significantly enhanced the Company's understanding of the mineralizing system and potential porphyry and CRD (carbonate replacement deposit) vectors at Madison.

Recent fieldwork has focused on maximizing value from short windows of underground access, where uninterrupted time underground is critical to collecting high-quality geological and geochemical data. These efforts have yielded the following:

• Newly exposed 150 feet of ramp due to lower water levels.
  A drop in the underground water level, due to a seasonal drop in moisture, has temporarily exposed approximately 150 feet of additional decline that has not been available for systematic sampling or mapping (see Image 1). This zone is highly altered and, despite having never been sampled before, is considered a high-priority target for detailed geological, structural and geochemical work. The current low-water conditions provide a time-sensitive opportunity to collect data that may not be accessible again, should the water level rise. While there is no guarantee of persistent high-grade mineralization in this horizon, the geologic information gained is of substantial importance for understanding metal distribution and refining drill targeting.

• Discovery of phreatic breccia linking underground workings to the Victoria Pit
  In the east rib, approximately 700 feet from the portal, geologists have identified a well-developed phreatic breccia with intrusive clasts containing chalcocite veins and native copper, that appears to align with the Victoria Pit at surface (see image 2). With this discovery, at least six distinct breccia types have now been recognized at Madison, underscoring the complexity and vigor of the hydrothermal system. Phreatic breccias form in very specific environments and, in this case, the most logical interpretation is that ascending water and steam generated from interaction between groundwater and cooling magma are responsible. The new exposure provides a second control point on this breccia body, allowing the technical team to define its rake and plunge-an important tool for vectoring toward a potential porphyry source. Historically, predictive modeling at Madison has relied heavily on geochemical and geophysical datasets; the addition of robust underground rock exposures, bolsters confidence in the team's efforts. The newly mapped breccia geometry strengthens the geological framework that underpins the Company's exploration model.

"These are the kinds of discoveries that only come from sustained, detailed work underground," commented Warwick Smith, CEO of American Pacific Mining. "The newly exposed, highly altered decline has revealed a well-defined phreatic breccia linking underground workings to surface giving our team tangible, geology based vectors that significantly sharpen our exploration model at Madison ahead of our planned drill program beginning this quarter. It's an exciting step forward that differentiates our technical approach from previous operators."
