早些时候报道：美国锑公司在蒙大拿州辉锑矿山开始勘探和批量取样作业

DALLAS, TX, 271 / ACCESS Newswire / October 17, 2025 / United States Antimony Corporation ("USAC," "US Antimony," the "Company"), (NYSE:UAMY)(NYSE Texas:UAMY), a leading producer and processor of antimony, zeolite, and other critical minerals, announced today that after obtaining the necessary permits from the Department of Environmental Quality ("DEQ") this month, the Company immediately initiated exploration and bulk sampling operations on Stibnite Hill, which is located directly adjacent to our Thompson Falls, Montana smeltering operation that is currently under significant expansion.

Antimony ore has now been trucked in a number of loads off the mountain to a flotation mill in Montana for crushing and sampling prior to further review by our metallurgical chemist. Management is highly encouraged due to the high quality of this material.

Commenting on this significant achievement announced today, Joe Bardswich, Executive Vice President and Chief Mining Engineer for USAC said, "Earlier this year, we began the process of acquiring mineral leases and actual real property purchases in and around the Stibnite Hill mine previously operated and mined by the Company over twenty years ago. Once the necessary permits were obtained from the DEQ this month, we began our exploration efforts. Those have resulted in our first four loads of raw antimony ore for our existing operations to begin processing this year. While we fully expected our first actual product from the Company to come from our Alaska operations, the delay in permit approvals in that state for approximately five months, allowed Montana to be first. This achievement now makes United States Antimony Corporation the first company in the world to be fully integrated from mining operations to finished products of antimony."
