United
States Antimony Announces
Shawn
Winkler Appointed as Interim Chief Financial Officer
“The
Critical Minerals and ZEO Company”
~
Antimony, Cobalt, Tungsten, and Zeolite ~
DALLAS, TX / ACCESS Newswire / May
6, 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, today
announced that Richard Isaak, the Company’s Senior Vice President and Chief Financial Officer, has commenced a temporary personal
leave of absence effective May 4, 2026. The Board of Directors has appointed Shawn Winkler, the Company’s prior Financial Consultant,
to serve as Interim Chief Financial
Officer during Mr. Isaak’s absence,
effective May 4, 2026.
Mr. Isaak’s
leave is strictly personal related and has nothing to do with the Company’s financial performance, accounting practices, internal
controls, or any matter involving the Company’s financial reporting. Mr. Isaak is expected to return to his role following the
conclusion of the leave, currently anticipated for a minimum of two months.
The Company confirms
that it remains on track to release First Quarter ending March 31, 2026 financial results on May 14, 2026, as previously announced. Mr.
Winkler has worked closely with Mr. Isaak throughout 2026 along with the other members of the finance team and is fully prepared to lead
the Company’s financial reporting process and upcoming earnings call.
Shawn Winkler
brings more than two decades of corporate finance, capital markets, and executive leadership experience to his role as Interim Chief
Financial Officer. He most recently served as Chief Financial Officer of Burrow Global, a Texas-based full-service engineering, procurement,
and construction firm serving the energy industry.
Prior to
his CFO tenure, Mr. Winkler spent 15 years as an investment banker at BMO Capital Markets and Deutsche Bank Securities, advising public
and private clients in the natural resources sector on more than $10 billion of M&A transactions. He led capital raises across the
full capital structure including IPOs, follow-on equity, high-yield and convertible notes, bank and institutional loans, and acquisition
financing associated with clients of the banks were he was employed.
Mr. Winkler
holds an MBA from Rice University's Jones Graduate School of Management, where he was named a Jones Scholar, and a Bachelor of Arts in
Economics, Managerial Studies, and Policy Studies, also from Rice University.
“Mr. Winkler
is a seasoned finance leader who has been part of our team for six months serving as an independent contractor,” said Gary C. Evans,
Chairman and CEO of US Antimony. “We are confident in his ability to take the lead of our ever growing financial team during this
period. I have personally known Shawn for approximately twenty years as he served as my prior commercial banker at both Deutsche Bank
and BMO Capital Markets. The entire Company joins me in sending Mr. Isaak our best wishes. When I hired Rick in July 2023, neither one
of us could have ever anticipated the incredible growth trajectory this company would be on over the last few years. He is an extremely
talented individual and deserves some time to recharge his batteries.”
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.
