About USAC:

United States Antimony Corporation and its subsidiaries

in the U.S., Mexico, and Canada ("USAC," “U.S. Antimony,” the "Company," "Our," "Us,"

or "We") sell antimony, zeolite, and precious metals primarily in the U.S., Mexico, and Canada. The Company mines, purchases,

and processes ore primarily into antimony oxide, antimony metal, antimony trisulfide, and precious metals at its facilities located in

Montana and Mexico. Antimony oxide is used to form a flame-retardant system for plastics, rubber, fiberglass, textile goods, paints, coatings,

and paper, as a color fastener in paint, and as a phosphorescent agent in fluorescent light bulbs. Antimony metal is used in bearings,

storage batteries, and ordnance. Antimony trisulfide is used as a primer in ammunition. The Company also recovers precious metals, primarily

gold and silver, at its Montana facility from third party ore. At its Bear River Zeolite (“BRZ”) facility located in Idaho,

the Company mines and processes zeolite, a group of industrial minerals used in water filtration, sewage treatment, nuclear waste and

other environmental cleanup, odor control, gas separation, animal nutrition, soil amendment and fertilizer, and other miscellaneous applications.

Beginning in 2024 and continuing in 2025, the Company acquired mining claims, real properties (patented claims) and leases located in

Alaska, Montana, and Ontario, Canada in an effort to reduce the cost of third-party antimony ore purchases and to expand its product offerings.
