Vancouver, British Columbia--(Newsfile Corp. - March 10, 2026) - American Pacific Mining Corp. (CSE: USGD) (OTCQX: USGDF) (FSE: 1QC1) ("American Pacific", or the "Company") is pleased to announce a compelling new geological observation from ongoing exploration work at its Madison Copper-Gold Project ("Madison" or the "Project") in Montana resulting in the successful application of a "fugitive calcite" black-light technique in newly revealed underground workings, which has contributed to an increased understanding of the mineralizing system at Madison. Recent fieldwork has taken advantage of a short seasonal window of greater underground access made possible by lower water levels revealing an additional 150 feet of newly exposed ramp access.
