United States

Antimony Announces

$100 Million

Share Repurchase Program

“The

Critical Minerals and ZEO Company”

Antimony, Gold, Tungsten, and Zeolite ~

DALLAS,

TX / ACCESS Newswire / August 19, 2026 / United States Antimony Corporation (“USAC,”

“US Antimony,” or the “Company”), (NYSE: UAMY) (NYSE Texas: UAMY), a leading

producer and processor of antimony, zeolite, and other critical minerals, and the only fully integrated antimony company in the world

outside of China and Russia, announced today that the Company’s Board of Directors has approved and authorized a share repurchase program

under which the Company may repurchase up to $100 million of its existing and outstanding common stock.

Repurchases under

the program may be made in the open market, in privately negotiated transactions, or otherwise, with the amount and timing of repurchases

to be determined at the discretion of the Company's Finance Committee as authorized by the Board of Directors, depending on market conditions

and corporate needs. Open market repurchases will be structured to occur in accordance with applicable federal securities laws, including

within the pricing and volume requirements of Rule 10b-18 under the Securities Exchange Act of 1934, as amended. The Company may also,

from time to time, enter into Rule 10b5-1 plans to facilitate repurchases of its shares under this authorization. This program does not

have a fixed expiration date, does not obligate US Antimony to acquire any particular amount of common stock, and may be modified, suspended,

or terminated at any time at the discretion of the Company's Board of Directors.

Commenting on this

announcement today, Mr. Gary C. Evans, Chairman and CEO of USAC, stated, “At our board meeting yesterday, our recent share price

was thoroughly discussed after a lengthy review of all USAC’s various projects located in the U.S., Canada, and Mexico. In light

of the future potential of the Company’s current activities and after a thorough review by the Board of Directors, it was determined

by unanimous consent, that the price of USAC’s common stock was deemed to be undervalued and the Company should implement the share

repurchase program today”.

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.
