History

United States Antimony Corporation, or USAC, was incorporated in Montana in January 1970 to mine and produce antimony products.
In December 1983, we suspended antimony mining operations but continued to produce antimony products from domestic and foreign
sources. In April 1998, we formed United States Antimony SA de CV or USAMSA, to mine and smelt antimony in Mexico. Bear River
Zeolite Company, or BRZ, was incorporated in 2000, and it is mining and producing zeolite in southeastern Idaho. On August 19, 2005,
USAC  formed Antimonio  de  Mexico,  S. A.  de  C. V.  to  explore  and  develop  antimony  and  silver  deposits  in  Mexico.  Our  principal
business is the production and sale of antimony, silver, gold, and zeolite products. On May 16, 2012, we started trading on the NYSE
MKT (now NYSE AMERICAN) under the symbol UAMY.

Antimony Division

Our antimony smelter and precious metals plant is located in the Burns Mining District of Sanders County, Montana, approximately 15
miles west of Thompson Falls, MT. We hold 2 patented mill sites where the plant is located. We have no “proven reserves” or “probable
reserves”  of  antimony,  as  these  terms  are  defined  by  the  Securities  and  Exchange  Commission.  Environmental  restrictions  preclude
mining at this site.

Mining was suspended in December 1983, because antimony could be purchased more economically from foreign sources.

For 2021, and since 1983, we relied on foreign sources for raw materials, and there are risks of interruption in procurement from these
sources and/or volatile changes in world market prices for these materials that are not controllable by us. We have sources of antimony
in Mexico but we are still depending on foreign companies for raw material in the future. We expect to receive raw materials from our
owned  and  leased  properties  for  2022  and  later  years. We  continue  working  with  suppliers  in  North America,  Central America,  and
South America.

We currently own 100% of the common stock, equipment, and the leases on real property of United States Antimony, Mexico S.A. de
C.V. or “USAMSA”, which was formed in April 1998. We currently own 100% of the stock in Antimony de Mexico SA de CV (ADM)
which owns the San Miguel concession of the Los Juarez property. USAMSA has two divisions, (1) the Madero smelter in Coahuila,
(2) the Puerto Blanco flotation mill and oxide circuit in Guanajuato. ADM possesses the Los Juarez mineral deposit.

In  our  existing  operations  in  Montana,  we  produce  antimony  oxide,  antimony  metal,  and  precious  metals. Antimony  oxide  is  a  fine,
white  powder  that  is  used  primarily  in  conjunction  with  a  halogen  to  form  a  synergistic  flame-retardant  system  for  plastics,  rubber,
fiberglass, textile goods, paints, coatings and paper. Antimony oxide is also used as a color fastener in paint, as a catalyst for production
of polyester resins for fibers and film, as a catalyst for production of polyethylene pthalate in plastic bottles, as a phosphorescent agent
in  fluorescent  light  bulbs,  and  as  an  opacifier  for  porcelains.  We  also  sell  antimony  metal  for  use  in  bearings,  storage  batteries  and
ordnance.

We  estimate  (but  have  not  independently  confirmed)  that  our  present  share  of  the  domestic  market  and  international  market  for
antimony oxide products is approximately 4% and less than 1%, respectively. We are the only significant U.S. producer of antimony
products, while China supplies 92% of the world antimony demand. We believe we are competitive both domestically and world-wide
due to the following:

·

·

·

·

·

·

We have a reputation for quality products delivered on a timely basis.

We have the only two operating, permitted, antimony smelters in North and Central America.

We are the only domestic producer of antimony products.

We can ship on short notice to domestic customers.

We are vertically integrated, with raw materials from our own mines, mills, and smelter in Mexico, along with the raw
materials from exclusive supply agreements we have with numerous ore and raw material suppliers.

Our smelter in Coahuila is the largest operating antimony smelter in Mexico or the United States with a current maximum
capacity of about 32,600 pounds of feed per day and permitting for 50% to 70% expansion.

Antimony Price Fluctuations: Our operating results have been, and will continue to be, related to the market prices of antimony metal,
which have fluctuated widely in recent years. The volatility of prices is illustrated by the following table, which sets forth the average
prices of antimony metal per pound, as reported by sources deemed reliable by us.

A five-year range of prices for antimony oxide and antimony metal, per pound, was as follows:

Antimony metal prices are determined by a number of variables over which we have no control. These include the availability and price
of  imported  metals,  the  quantity  of  new  metal  supply,  and  industrial  demand.  If  metal  prices  decline  and  remain  depressed,  our
revenues and profitability may be adversely affected.

We use various antimony raw materials to produce our products. We currently obtain antimony raw material from sources in Canada
and Mexico.

Zeolite Division

We own 100% of Bear River Zeolite Company, (BRZ, an Idaho corporation) that was incorporated on June 1, 2000. BRZ has a lease
with Webster Farm, L.L.C. that entitles BRZ to surface mine and process zeolite on property located near Preston, Idaho, in exchange
for  a  royalty  payment.  In  2010  the  royalty  was  adjusted  to  $10  per  ton  sold.  The  current  minimum  annual  royalty  is  $60,000.  In
addition, BRZ has more zeolite on U.S. Bureau of Land Management land. The Company pays various royalties on the sale of zeolite
products. William Raymond and Nancy Couse are paid a royalty that varies from $1 to $5 per ton. On a combined basis, royalties vary
from  8%-13%  of  sales.  Shortly  after  inception  BRZ  constructed  a  processing  plant  on  the  property  which  improved  its  productive
capacity. Ground-breaking for an additional warehouse to store additional inventory and a shop to service equipment started in 2021
and the warehouse and shop are expected to be completed by mid-2022. A vertical-shaft-impactor crusher was replaced by a hammer
mill for crushing line number 1 in 2021 for increased production rate. A replacement jaw crusher was installed and put into service in
2021.  The  new  jaw  crusher  was  further  improved  with  a  variable-speed  apron  feeder  in  late  2021  and  subsequent  and  substantial
improvements have been made to the jaw crusher in 2022. In 2021, the Company purchased a house in Preston Idaho for the express
purpose of housing workers for its zeolite operation.

We have no reserves nor resources of zeolite, as these terms are defined by the Securities and Exchange Commission.

“Zeolite” refers to a group of industrial minerals that consist of hydrated aluminosilicates that hold cations such as calcium, sodium,
ammonium, various heavy metals, and potassium in their crystal lattice. Water is loosely held in cavities in the lattice. BRZ zeolite is
regarded  as  one  of  the  best  zeolites  in  the  world  due  to  its  high  CEC  of  approximately  180-220  meq/100  gr.,  its  hardness  and  high
clinoptilolite content, its absence of clay minerals, and its low sodium content. BRZ’s zeolite deposits’ characteristics which make the
mineral useful for a variety of purposes including:

☐

Soil Amendment and Fertilizer. Zeolite has been successfully used to fertilize golf courses, sports fields, parks and common
areas, and high value agricultural crops

☐ Water Filtration. Zeolite is used for particulate, heavy metal and ammonium removal in swimming pools, municipal water

systems, fisheries, fish farms, and aquariums.

☐

Sewage Treatment. Zeolite is used in sewage treatment plants to remove nitrogen and as a carrier for microorganisms.

Nuclear  Waste  and  Other  Environmental  Cleanup.  Zeolite  has  shown  a  strong  ability  to  selectively  remove  strontium,
cesium, radium, uranium, and various other radioactive isotopes from solution. Zeolite can also be used for the cleanup of
soluble  metals  such  as  mercury,  chromium,  copper,  lead,  zinc,  arsenic,  molybdenum,  nickel,  cobalt,  antimony,  calcium,
silver and uranium.

Odor Control. A major cause of odor around cattle, hog, and poultry feed lots is the generation of the ammonium in urea
and manure. The ability of zeolite to absorb ammonium prevents the formation of ammonia gas, which disperses the odor.

Gas  Separation.  Zeolite  has  been  used  for  some  time  to  separate  gases,  to  re-oxygenate  downstream  water  from  sewage
plants,  smelters,  pulp  and  paper  plants,  and  fish  ponds  and  tanks,  and  to  remove  carbon  dioxide,  sulfur  dioxide  and
hydrogen  sulfide  from  methane  generators  as  organic  waste,  sanitary  landfills,  municipal  sewage  systems,  animal  waste
treatment facilities, and is excellent in pressure swing apparatuses.

Animal Nutrition. According to other research, feeding up to 2% zeolite increases growth rates, decreases conversion rates,
and prevents scours. BRZ does not make these claims.

☐ Miscellaneous Uses. Other uses include catalysts, petroleum refining, concrete, solar energy and heat exchange, desiccants,

pellet binding, horse and kitty litter, floor cleaner and carriers for insecticides, pesticides and herbicides.

Environmental Matters

Our exploration, development and production programs conducted in the United States are subject to local, state and federal regulations
regarding environmental protection. Some of our production and mining activities are conducted on public lands. We believe that our
current discharge of waste materials from our processing facilities is in material compliance with environmental regulations and health
and  safety  standards. The  U.S.  Forest  Service  extensively  regulates  mining  operations  conducted  in  National  Forests.  Department  of
Interior regulations cover mining operations carried out on most other public lands. All operations by us involving the exploration for or
the production of minerals are subject to existing laws and regulations relating to exploration procedures, safety precautions, employee
health and safety, air quality standards, pollution of water sources, waste materials, odor, noise, dust and other environmental protection
requirements  adopted  by  federal,  state  and  local  governmental  authorities. We  may  be  required  to  prepare  and  present  data  to  these
regulatory authorities pertaining to the effect or impact that any proposed exploration for, or production of, minerals may have upon the
environment.  Any  changes  to  our  reclamation  and  remediation  plans,  which  may  be  required  due  to  changes  in  state  or  federal
regulations, could have an adverse effect on our operations. The range of reasonably possible loss in excess of the amounts accrued, by
site, cannot be reasonably estimated at this time.

We  accrue  environmental  liabilities  when  the  occurrence  of  such  liabilities  is  probable  and  the  costs  are  reasonably  estimable.  The
initial  accruals  for  all  our  sites  are  based  on  comprehensive  remediation  plans  approved  by  the  various  regulatory  agencies  in
connection with permitting or bonding requirements. Our accruals are further based on presently enacted regulatory requirements and
adjusted only when changes in requirements occur or when we revise our estimate of costs to comply with existing requirements. As
remediation activity has physically commenced, we have been able to refine and revise our estimates of costs required to fulfill future
environmental  tasks  based  on  contemporaneous  cost  information,  operating  experience,  and  changes  in  regulatory  requirements.  In
instances  where  costs  required  to  complete  our  remaining  environmental  obligations  are  clearly  determined  to  be  in  excess  of  the
existing  accrual,  we  have  adjusted  the  accrual  accordingly.  When  regulatory  agencies  require  additional  tasks  to  be  performed  in
connection  with  our  environmental  responsibilities,  we  evaluate  the  costs  required  to  perform  those  tasks  and  adjust  our  accrual
accordingly,  as  the  information  becomes  available.  In  all  cases,  however,  our  accrual  at  year-end  is  based  on  the  best  information
available at that time to develop estimates of environmental liabilities.

Antimony Processing Site

We have environmental remediation obligations at our antimony processing site near Thompson Falls, Montana (“the Stibnite Hill Mine
Site”).  We  are  under  the  regulatory  jurisdiction  of  the  U.S.  Forest  Service  and  subject  to  the  operating  permit  requirements  of  the
Montana  Department  of  Environmental  Quality.  At  December  31,  2021  and  2020,  we  have  accrued  $100,000  to  fulfill  our
environmental responsibilities.

BRZ

uamy_10k.htm

During  2001,  we  recorded  a  reclamation  accrual  for  our  BRZ  subsidiary,  based  on  an  analysis  performed  by  us  and  reviewed  and
approved  by  regulatory  authorities  for  environmental  bonding  purposes.  The  accrual  of  $7,500  represents  our  estimated  costs  of
reclaiming,  in  accordance  with  regulatory  requirements,  the  acreage  disturbed  by  our  zeolite  operations,  and  remains  unchanged  at
December 31, 2021.

General

Reclamation  activities  at  the  Thompson  Falls  Antimony  Plant  were  performed  under  supervision  of  the  U.S.  Forest  Service  and
Montana Department of Environmental Quality. We have complied with regulators’ requirements and do not expect the imposition of
substantial additional requirements.

We have posted cash performance bonds with a bank and the U.S. Forest Service in connection with our reclamation activities.

We believe we have accrued adequate reserves to fulfill our environmental remediation responsibilities as of December 31, 2021 and
2020. We have made significant reclamation and remediation progress on all our properties over thirty years and have complied with
regulatory requirements in our environmental remediation efforts.

Employees

As of December 31, 2021, we employed 17 full-time employees in Montana. In addition, we employed 25 people at our zeolite plant in
Idaho,  and  27  employees  at  our  mining,  milling  and  smelting  operation  in  Mexico.  The  number  of  full-time  employees  may  vary
seasonally. None of our employees are covered by any collective bargaining agreement.

Other

We hold no material patents, licenses, franchises or concessions. However, we consider our antimony processing plants proprietary in
nature.

We  are  subject  to  the  requirements  of  the  Federal  Mining  Safety  and  Health  Act  of  1977,  the  Occupational  Safety  and  Health
Administration’s regulations, requirements of the state of Montana and the state of Idaho, federal and state health and safety statutes
and Sanders County, Montana and Franklin County, Idaho health ordinances.

Item 1A Risk Factors

There may be events in the future that we are not able to accurately predict or over which we have no control. The risk factors listed
below, as well as any cautionary language in this report, provide examples of risks, uncertainties and events that may cause our actual
results to differ materially from the expectations we describe in our forward-looking statements.

If we were liquidated, our common stockholders could lose part, or all, of their investment.

In the event of our dissolution, the proceeds, if any, realized from the liquidation of our assets will be distributed to our stockholders
only after the satisfaction of the claims of our creditors and preferred stockholders. The ability of a purchaser of shares to recover all, or
any  portion,  of  the  purchase  price  for  the  shares,  in  that  event,  will  depend  on  the  amount  of  funds  realized  and  the  claims  to  be

We may have unasserted liabilities for environmental reclamation.

Our  research,  development,  manufacturing  and  production  processes  involve  the  controlled  use  of  hazardous  materials,  and  we  are
subject to various environmental and occupational safety laws and regulations governing the use, manufacture, storage, handling, and
disposal  of  hazardous  materials  and  some  waste  products.  The  risk  of  accidental  contamination  or  injury  from  hazardous  materials
cannot be completely eliminated. In the event of an accident, we could be held liable for any damages that result and any liability could
exceed our financial resources. We also have one ongoing environmental reclamation and remediation project at our current production
facility  in  Montana. Adequate  financial  resources  may  not  be  available  to  ultimately  finish  the  reclamation  activities  if  changes  in
environmental  laws  and  regulations  occur,  and  these  changes  could  adversely  affect  our  cash  flow  and  profitability. We  do  not  have
environmental liability insurance now, and we do not expect to be able to obtain insurance at a reasonable cost. If we incur liability for
environmental damages while we are uninsured, it could have a harmful effect on our financial condition and results of operations. The

We have accruals for asset retirement obligations and environmental obligations.

We have accruals totaling $298,649 on our balance sheet at December 31, 2021, for our environmental reclamation responsibilities and
estimated asset retirement obligations. If we are not able to adequately perform these activities on a timely basis, we could be subject to
fines and penalties from regulatory agencies.

Global health crises may adversely affect our planned operations.

Our business could be materially and adversely affected by the risks, or the public perception of the risks, related to a pandemic or other
health crisis, such as the recent outbreak of novel coronavirus (COVID-19). A significant outbreak of contagious diseases in the human
population could result in a widespread health crisis that could adversely affect our planned operations. Such events could result in the
complete or partial closure of our operations. In addition, it could impact economies and financial markets, resulting in an economic
downturn that could impact our ability to raise capital.

Item 2 Description of Properties

ANTIMONY DIVISION

Our antimony smelter and precious metals plant is located in the Burns Mining District, Sanders County, Montana, approximately 14
miles west of Thompson Falls on Montana Highway 471. This highway is asphalt, and the property is accessed by cars and trucks. The
property includes two five-acre patented mill sites that are owned in fee-simple by us. The claims are U. S. Antimony Mill Site No. 1
(Mineral Survey 10953) and U. S. Antimony Mill Site No. 2 (Mineral Survey 10953). We also own five-acre Black Jack millsite.

The U. S. Antimony Mill Sites were used to run a flotation mill and processing plant for antimony that we mined on adjacent claims
that have been sold. Presently, we run a smelter that includes furnaces of a proprietary design to produce antimony metal, antimony
oxide, and various other products. We also run a precious metals plant. The facility includes 6 buildings and our main office. There are
no plans to resume mining on the claims that have been sold or abandoned, although the mineral rights have been retained on many of
the  patented  mining  claims.  The  U.  S.  Forest  Service  and  Montana  Department  of  Environmental  Quality  have  told  us  that  the
resumption of mining would require an Environmental Impact Statement, massive cash bonding, and would be followed by years of
lawsuits. The mill site is serviced with three-phase electricity from Northwest Power, and water is pumped from a well.

We claim no reserves nor mineral resources on any of these properties.

Antimony mining and milling operations in the U.S. were curtailed during 1983 due to continued declines in the price of antimony. We
are  currently  purchasing  foreign  raw  antimony  materials  and  producing  our  own  raw  materials  from  our  properties  in  Mexico.  We
continue to produce antimony metal, oxide, sodium antimonite, antimony trisulfide, and precious metals from our processing facility
near Thompson Falls, Montana.

Part of the USAC Mexican property, including San Miguel I, II and part of San Juan III, was originally drilled by the Penoles Company
in 1970, when antimony metal prices were high. They did not proceed with the property, due to the complex metallurgy of antimony.
Subsequently, the Mexican Government did additional work and reported a deposit of mineralized material of 1,000,000 metric tons
(mt) grading 1.8% antimony and 8.1 ounces of silver per metric ton (opmt) in Consejo de Recursos Minerales (Publicacion M-4e). Such
a report does not qualify as a comprehensive evaluation, such as a final or bankable feasibility study that concludes legal and technical
viability, and economic feasibility. The Securities and Exchange Commission does not recognize this report, and we claim no reserves.

The  mineralized  zone  is  a  classic  jasperoid-type  deposit  in  the  Cretaceous  El  Doctor  Limestone.  The  mineralization  is  confined  to
silicified jasperoid pipes intruded upwards into limestone. The zone strikes north 70 degrees west. The dimension of the deposit is still
conjectural. However, the strike length of the jasperoid is more than 3,500 meters. 

The mineralization is typically very fine-grained stibnite with silver and gold. It is primarily sulfide in nature due to its encapsulation in
silica. The  mining  for  many  years  will  be  by  open  pit  methods.  Eventually  it  will  be  by  underground  methods. At  the  present  time,
mining has included hauling dump rock and rock from mine faces.

In October 2020, a 1000 meter initial drill program was conducted on the property with a total of 25 holes. The drilling was completed
November 2020 and used a reverse-circulation drill rig. Samples were sent to a certified lab in Mexico for analysis. Drill hole location,
depth, and angle were selected near mined pit areas and along suspected fault zones. A summary of the drill program was published in a
news release of November 30, 2020 and subsequent news releases. This initial program was performed without the aid of a geophysical
study.  In  2022,  the  Company  is  engaged  in  a  formal  geological,  geochemical,  and  geophysical  study  to  help  obtain  subsurface
mineralization data and better understand the system with an objective of partnering with a junior mining company with expertise in
exploration/drilling.

USAMSA Puerto Blanco Flotation Mill, Guanajuato, Mexico

The flotation plant has a capacity of 100 metric tons per day. It includes a 30” x 42” jaw crusher, a 4’x 8’ double-deck screen, a 36”
cone  crusher,  an  8’x  36”  Harding  type  ball  mill,  and  eight  No.  24  Denver  sub A  type  flotation  machines,  an  8’  disc  filter,  front  end
loaders, tools and other equipment. The flotation circuit is used for the processing of rock from Los Juarez and other properties. The
crushing equipment currently in place is adequate for both flotation mills. An oxide circuit was added to the plant in 2013 and 2014 to
mill  oxide  ores  from  Los  Juarez  and  other  properties.  It  includes  a  vertical  shaft  impactor,  3  ore  bins,  8  conveyors,  a  4’  x  6’  high
frequency screen, jig, 8 standard concentrating tables, 5 pumps, sand screw and two buildings. The capacity of the oxide circuit is 50
tons  per  day. We  have  installed  a  cyanide  leach  circuit  and  settling  pond  that  will  be  used  to  recover  precious  metals  from  our  Los
Juarez mine. In 2019 a cyanide leach circuit for recovery of gold was built and permits were obtained for this circuit. Test batches of
Los Juarez antimony concentrates containing precious metals have been processed through the cyanide leach system and the processing
of 2,000 tons of mined rock from Los Juarez is underway. One of three batches of gold-bearing carbon (the end product of the cyanide
leach) have been saturated and awaits separation and analysis. Preliminary results are that the gold-recovery is acceptable.

USAMSA Madero Smelter, Estacion Madero, Parras De La Fuente, Coahuila, Mexico

USAC, through its wholly owned subsidiary, USAMSA, owns and operates a smelting facility at Estacion Madero, in the Municipio of
Parras de la Fuente, Coahuila, Mexico. The property includes 13.48 hectares (30 acres). Seventeen small rotating furnaces (SRF’s) and
four large rotating furnaces (LRF) with an associated stack and scrubbers. Other equipment includes cooling ducting, dust collectors,
scrubber,  laboratory,  warehouse,  slag  vault,  stack,  jaw  crusher,  screen,  hammer  mill,  and  a  3.5’  x  8’  rod  mill.  The  plant  has  a  feed
capacity of 14-25 metric tons of direct shipping ore per day, depending on the grade of the feedstock. If the feedstock is in the range of
45% antimony or higher, the smelter could produce as much as 10MM pounds of contained antimony annually. Concentrates from our
flotation plant, and hand-sorted ore from Mexico sources and other areas, are being processed. In 2019, we completed the installation of
a  caustic  leach  circuit  to  process  concentrates  from  the  Puerto  Blanco  cyanide  leach  plant  containing  precious  metals  from  our  Los
Juarez Mining property. The Madero production is either sold as metal to customers directly or crude oxide shipped to our Montana
plant  to  produce  finished  antimony  products  and  precious  metals.  Plans  to  dramatically  improve  and  update  the  infrastructure  at  the
Madero Smelter include erecting a building around all the furnaces to aid in the control, consistency, and quality of product and ease of
processing. Additionally,  the  Company  is  considering  producing  finished  antimony  oxide  with  this  control  and  purchasing  quality-
control instrumentation for the option of selling all finished antimony products from Madero just as we currently do in Montana. We
intend  to  use  part  of  our  2021  capital  raise  for  the  buildings,  improving  equipment,  relining  furnaces,  purchase  of  newer  forklifts,
scales, and general improvement. Access to the plant is by road and railroad. Set forth below are location maps:

Property and Ownership  

BRZ leases 320 acres from the Webster Farm, L.L.C. The term of the lease is 15 years and it began on March 1, 2010. This includes the
mill site and zeolite in the area of the open pit. The property is the NW ¼ and W ½ of the SW ¼ of section 3 and the N ½ of the W ¼ of
section 10, Township 15 South, Range 40 East of the Boise Meridian, Franklin County, Idaho. The lease requires a payment of $10.00
per ton plus an additional annual payment of $10,000 on March 1st of each year. In addition, there are two other royalty holders. Nick
Raymond and the estate of George Desborough each have a graduated royalty of $1.00 per ton to $5.00 per ton, depending on the sale
price. In early 2021, Joe Bardswhich, a director and geologist, was able to renegotiate one of the royalty payments so that escalation
due to the CPI that existed in the original contract was removed.

The  balance  of  the  property  is  on  Bureau  of  Land  Management  property  and  includes  480  acres  held  by  24,  20-acre  Placer  claims.
Should we drop our lease with Webster Farms LLC., we will retain these placer claims.

Geology

The  deposit  is  a  very  thick,  sedimentary  deposit  of  zeolitized  volcanic  ash  of  Tertiary  age  known  as  the  Salt  Lake  Formation.  The
sedimentary  interval  in  which  the  clinoptilolite  occurs  is  more  than  1000  feet  thick  in  the  area.  Thick  intervals  of  the  zeolite  are
separated by thin limestone and sandstone beds deposited in the freshwater lake where the volcanic ash accumulated.

The  deposit  includes  an  800-  foot  mountain.  Zeolite  can  be  sampled  over  a  vertical  extent  of  800  feet  on  more  than  700  acres. The
current pit covers more than 3 acres. Despite the apparent size of the deposit, we claim no reserves.

Exploration, Development, and Mining

Exploration has been limited to the examination and sampling of surface outcrops and mine faces.

Mining Methods

Depending on the location, the zeolite is overlain by 1 to 12 feet of zeolite-rich soil. On the ridges, the cover is very little, and in the
draws the soil is thicker. The overburden is stripped using a tractor dozer, currently a Caterpillar D-8K. It is moved to the toe of the pit,
and will eventually be dozed back over the pit for reclamation.

Although near-surface rock is easily ripped, it is more economical to drill and blast it. Breakage is generally good. Initial benches are
20 feet high, and each bench is accessed by a road.

Haulage is over approximately 4,000 feet of road on an uphill grade of 2.5% to the mill. On higher benches, the grade will eventually
be downhill. Caterpillar 769 B rock trucks are being used. They haul 18 to 20 tons per load, and the cycle time is about 30 minutes.

In 2021, we experimented with the idea of mining principally by ripping using the Caterpillar D-9. This method worked but rendered
rock that sometimes had to be drilled and broken in order to fit in the jaw crusher bin at the mill. Consequently, the Company is certain
that blasting is the preferred method of mining. We may elect to supplement mining production by updating our D-9 with a secondary
ripper.

With the trucks and the other existing equipment, the mine is capable of producing 80 tons per hour.

MILLING

Primary Crusher

The primary crushing circuit is a conventional closed circuit, utilizing a Stephens-Adamson 42” x 12’ apron feeder, Pioneer 30” x 42”
jaw crusher, Nordberg standard 3’ cone crusher, a 5’ by 12’ double deck Kohlberg screen, and has a self-cleaning dust collector. The
rock is crushed to minus 1 inch and the circuit has a rated capacity of more than 50 tons per hour.

Dryer

There are two dryer circuits, one for lines one and two, and one for the Raymond mill. The dryer circuits include one 50 ton feed bin,
and each dryer has a conveyor bypass around each dryer, a bucket elevator, and a dry rock bin. The dryers are 25 feet long, 5 feet in
diameter and are fired with propane burners rated at 750,000 BTUs. One self-cleaning bag house services both dryers. Depending on
the wetness of the feed rock, the capacity is in the range of 10 tons per hour per dryer. During most of the year, the dryers are not run.

Coarse Products Circuit

In  Oct/Nov  2021  the  primary  jaw  crusher  pitman  arm  broke  due  to  incorrect  greasing  procedures. A  replacement  jaw  crusher  was
purchased, delivered, installed and began operations 1.5 months after delivery. A delivery chute was designed and fabricated along with
necessary bins and skirting. The new jaw crusher was outfitted with a hydraulic hand-pump greaser for the main pitman-arm assembly
and  the  correct  grease  and  greasing  procedure  has  been  implemented.  Plans  to  fix  or  replace  the  old  jaw  crusher  exist  but  require  a
major refit. The Company was able to repair the engine on its crane, a Linkbelt 3-stage boom crane of about 50 ton nameplate capacity.
The transmission is now being repaired. With this crane, the Company will pull the old jaw crusher and determine if it is salvageable. In
any  case,  the  Company  has  earmarked  that  location  for  an  entirely  new  and  secondary  jaw  crusher  in  the  event  that  bulk  zeolite
purchase opportunities increase.

There are two lines to produce coarse products:

·

·

Line 1 is a closed circuit with a 100 HP hammer mill (that replaced the old vertical shaft impactor) and a 5 deck Midwestern
Multi  Vibe  high  frequency  screen.  The  replacement  of  the  VSI  with  the  hammermill,  also  outfitted  with  a  variable
frequency drive has increased production over the VSI by about 50% so far and we are continuing to test feeds and speeds
to enhance this production rate.

Line 2 includes a Jeffries 30” by 24” 60 HP hammer mill in a closed circuit with two 5’ x 12’ triple deck Midwestern Multi
Vibe high frequency screens. The circuits also include bucket elevators, (3) 125-ton capacity product silos, a 6 ton capacity
Crust Buster blender, augers, Sweco screens, and dust collectors.

Fine Products Circuit

The  fine  products  circuit  is  in  one  building  and  it  includes  (2)  3.5’  x  10.5’  Derrick  2  deck  high  frequency  (3450  RPM)  screens  and
various  bucket  elevators,  augers,  bins,  and  Sweco  screens  for  handling  product.  Depending  on  the  screening  sizes,  the  plants  can
generate approximately 150 tons of granules and 125 tons of fines per 24-hour day.

Raymond Mill Circuit

The Raymond mill circuit includes a 6058 high-side Raymond mill with a double whizzer, dust collector, two 100 ton product silos,
feed bin, conveyors, air slide, bucket elevators, and control booth. The Raymond mill has a rated capacity of more than 10 tons per
hour.

Overview

Company-wide

uamy_10k.htm

For the year ended December 31, 2021, we reported net loss of $60,469 after depreciation and amortization of $880,880, compared to a
net loss of $3,286,804 for 2020 after depreciation and amortization of $885,843.

During the year ending December 31, 2021, the most significant factors affecting our financial performance were as follows:

·
·
·
·
·
·
·
·
·

Two private placements of stock during the first quarter of 2021.
A significant, steady, and pronounced increase of the London Metals Bulletin price of antimony.
The efforts in sales of zeolite of our zeolite sales director, Gretchen Lawrence.
The addition of an antimony sales director, Mitzi Hart.
The complete restructuring of office and plant personnel and procedures at the Montana and BRZ facilities.
Increased trucking prices and decreasing trucking availability
Difficulties in sourcing labor due to the Covid pandemic and the relief funding to curtail the incentive to work.
The renegotiation of various supply, treatment, royalty, and tolling agreements.
The retirement of several outstanding, old, and significant debts.

During the year ended December 31, 2021, the most significant event affecting our financial performance was the addition of over $23
million  to  our  working  capital  via  two  capital  raises  of  common  stock.  These  funds  allowed  the  Company  to  retire  much  of  its
outstanding debt. It also allowed the Company leverage to re-negotiate existing contracts and pursue previously prohibitive ventures.
The fact that the Company could pay its bills on time resulted in a serious amount of restructuring and the ability to offer more to attract
and retain labor.

Our plan for 2022 is as follows:

·
·
·
·

·
·
·
·

·
·

·
·

·

In  addition  to  the  processing  goals  stated  above,  the  Company  intends  to  continue  to  improve  its  production  capacity  and  sales  of
zeolite  at  its  subsidiary  Bear  River  Zeolite.  These  goals  will  be  aided  by  the  additional  100’  by  50’  warehouse  for  the  storage  and
stockpile of product and also its 60’ x 40’ shop building, both of which should be completed in the first half of 2022. Also, the purchase
of a Caterpillar 740 haul truck is underway to replace the defunct haul truck we had. The Company plans to purchase a replacement
front-end loader for the mine to replace its 988-B Caterpillar that is on its last legs. The Company plans to then update the rippers on
both Cat D-8 and D-9 supplement mining. A secondary, winter-storage platform located between the mine and the mill is planned. Salt
sheds for these ore storage locations are planned to eliminate the necessity of the use of tarps for keeping the zeolite dry during the
winter and rainy seasons.

The following are highlights of the significant changes during 2021:     

Antimony:

Zeolite:

The sale of antimony during 2021 was 911,079 lbs. compared to 815,310 pounds in 2020, an increase of 11.7%.

The average sales price of antimony during 2021 was $5.29/lb. compared with $3.61/lb. in 2020, an increase of $1.68/lb. (a
46.5% increase). During the beginning of 2022, the Rotterdam price of antimony is approximately $6.06/lb. per pound.

We are producing and buying raw materials, which will allow us to ensure a steady flow of products for sale. Our smelter at
Madero,  Mexico,  was  producing  primarily  ores  from  the Wadley  mines  in  2021.  Our  smelter  in  Montana  was  producing
material from both Mexico and our North American sources in 2021. Raw materials from our North American supplier was
reduced in 2021 due to the effects of Covid and shipping difficulties.

We  produced  ingots  of  antimony  metal  in  2021  to  be  shipped  directly  to  customers  from  our  Madero  smelter  starting  in
2022. We intend to increase this for 2022 and beyond. This will significantly reduce our production and shipping costs.

We are proceeding with the processing of Los Juarez ore in the 100 ton per day mill at Puerto Blanco. Due to the hardness
of the jasperoid rock at Los Juarez, it has been determined that the actual through-put is more like 80 tons per day.

During 2021, the Company sold 11,747 tons compared to 10,661 tons in 2020, an increase of 1,086 tons (10.1%). Bear River Zeolite
(“BRZ”) realized a gross profit of $340,806 (13.1% of sales) in 2021 compared to a gross profit of $323,780 (15.3% of sales) in 2020.
Net  income  for  the  BRZ  segment  was  $193,675  for  the  year  ended  December  31,  2021  compared  to  $262,861  for  the  year  ended
December 31, 2020.

Corporate-wide:

During the year ending December 31, 2021, the following transactions had a material impact on the Company’s net loss:

·

·

On April  20,  2020,  the  Company  received  a  loan  of  $443,400  pursuant  to  the  Paycheck  Protection  Program  (the  “PPP”)
under  Division A,  Title  I  of  the  CARES Act,  which  was  enacted  March  27,  2020.  During  the  year  ended  December  31,
2021, the Company received notification that the loan had been forgiven. The amount of the loan, $443,400, was recognized
as gain on forgiveness of the CARES Act loan.

On November 7, 2014, the Company entered into an advance and concentrate processing agreement with Hillgrove Mines
Pty  Ltd  of Australia  (Hillgrove)  in  which  the  Company  was  advanced  funds  from  Hillgrove  to  build  facilities  to  process
Hillgrove  antimony  concentrate.  The  Company  has  not  processed  Hillgrove  concentrate  for  more  than  two  years.  The
balance  of  the  advance  liability  due  was  $1,134,221  at  December  31,  2020.  In  April  2021,  the  Company  successfully
negotiated a settlement with Red River for an agreed upon amount of $1,020,799 which was paid on paid on April 8, 2021.
The Company recognized a gain on settlement of the advance in the amount of $113,422 during the year ended December
31, 2021 (Note 8)

Starting in August of 2021, US Antimony negotiated with our Canadian feed source for a more favorable treatment charge
contract to replace the previous one. This contract became effective in December of 2021 and represents an improvement
from the previous treatment charge contract.

Throughout 2021, the price of antimony increased steadily.

Throughout  2021,  the  price  of  trucking,  lumber  (for  pallets),  fuel,  and  labor  increased.  The  Company  raised  its  starting
wages twice at the facility in Montana and once at Bear River Zeolite.

During 2021, we saw our average sale price for antimony increase by $1.68/lb from an average of $3.61/lb in 2020 to $5.29/lb in 2021.

In the 4th quarter 2021, the Company renegotiated a treatment-charge contract with its North American supplier of sodium antimonate.
This  contract  renegotiation  became  effective  in  December  2021  and  will  result  in  a  more  favorable  price  of  purchased  antimony
contained that had previously existed.

During 2020, we saw our average sale price increase by $0.13 per pound from an average of $3.48 per pound for 2019 to an average of
$3.61  per  pound  for  2020.  Following  the  change  in  management  in  June  and  the  suppressed  price  of  antimony,  the  Company
temporarily suspended sale of antimony oxide. This decision was made principally in order to minimize the loss per pound in sales at a
time for which our production acquisition contracts were being renegotiated. As consequence of these decisions, the Company was, as
of the first quarter of 2021, obtaining its raw materials from its Mexican sources at a substantial savings as compared to the previous
year. These savings were due to the withdrawal of overhead from the staff it had at the Wadley mine.

Additionally,  the  Company  is  now  processing  antimony  products  at  its  Madero  facility  at  a  substantial  savings  compared  with  all
previous years. These savings were due to the renegotiating of its natural gas contract for the Madero smelter which was completed in
early 2021. Furthermore, the Company has been able to produce finished antimony ingots and will sell them directly from its Madero
facility starting in 2022. This saves at least $0.29/lb in shipping to and the finishing costs at Montana.

Our  net  working  capital  increased  $24,217,520  for  the  year  ended  December  31,  2021  from  a  negative  amount  of  $2,669,382  at  the
beginning of the year to $21,548,138 at the end of the year. Current assets increased due to an increase in cash and cash equivalents.
Our  current  liabilities  decreased  by  $2,456,690  which  included  a  decrease  of  approximately  $662,140  in  accounts  payables  and
payables to related parties, a decrease of $1,120,730 due to Mexican export tax liability. Capital improvements were paid for with cash.

For the year ending December 31, 2022, we are planning to use funds acquired from the two stock offerings raised in 2021 to make
significant improvements to our operations at Madero, Puerto Blanco, Bear River Zeolite, and Thompson Falls facilities with the goal
of increasing production and decreasing costs.

Critical Accounting Estimates

We  have,  besides  our  estimates  of  the  amount  of  depreciation  on  our  assets,  two  critical  accounting  estimates.  The  percentage  of
antimony contained in our unprocessed ore in inventory is based on assays taken at the time the ore is delivered, and may vary when the
ore  is  processed. Also,  the  asset  recovery  obligation  on  our  balance  sheet  is  based  on  an  estimate  of  the  future  cost  to  recover  and
remediate our properties as required by our permits upon cessation of our operations, and may differ when we cease operations.

·

·

The  value  of  unprocessed  ore  is  based  on  assays  taken  at  the  time  the  ore  is  delivered,  and  may  vary  when  the  ore  is
processed. We assay the ore to estimate the amount of antimony contained per metric ton, and then make a payment based
on  the  Rotterdam  price  of  antimony  and  the  %  of  antimony  contained.  Our  payment  scale  incorporates  a  penalty  for  ore
with  a  low  percentage  of  antimony.  It  is  reasonably  likely  that  the  initial  assay  will  differ  from  the  amount  of  metal
recovered from a given lot. If the initial assay of a lot of ore on hand at the end of a reporting period were different, it would
cause a change in our reported inventory, but would not change our accounts payable, reported cost of goods sold or net
income amounts. Our net income would not be affected. Direct shipping ore (DSO) purchased at our Madero smelter is paid
for at a fixed amount at the time of delivery and assaying, and is not subject to accounting estimates. The amount of the
accounting  estimate  for  purchased  ore  at  our  Puerto  Blanco  mill  is  in  a  constant  state  of  change  because  the  amount  of
purchased ore and the per cent of metal contained are constantly changing. Due to the amount of ore on hand at the end of a
reporting  period,  as  compared  to  the  amount  of  total  assets,  liabilities,  equity,  and  the  ore  processed  during  a  reporting
period, any change in the amount of estimated metal contained would likely not result in a material change to our financial
condition.

The  asset  retirement  obligation  and  asset  on  our  balance  sheet  is  based  on  an  estimate  of  the  future  cost  to  recover  and
remediate  our  properties  as  required  by  our  permits  upon  cessation  of  our  operations,  and  may  differ  when  we  cease
operations. We make periodic reviews of the remaining life of the mine and other operations, and the estimated remediation
costs  upon  closure,  and  adjust  our  account  balances  accordingly. At  this  time,  we  think  that  an  adjustment  in  our  asset
recovery  obligation  is  not  required,  and  an  adjustment  in  future  periods  would  not  have  a  material  impact  in  the  year  of
adjustment,  but  would  change  the  amount  of  the  annual  accretion  and  amortization  costs  charged  to  our  expenses  by  an
undetermined amount.

Evaluation of disclosure controls and procedures

At the end of the period covered by this Annual Report on Form 10-K, an evaluation was carried out under the supervision of and with
the participation of our management, including the Principal Executive Officer and the Principal Financial Officer of the effectiveness
of the design and operations of our disclosure controls and procedures (as defined in Rule 13a – 15(e) and Rule 15d – 15(e) under the

under  the  Exchange Act  is  recorded,  processed,  summarized,  and  reported  within  the  time  periods  specified  in  applicable  rules  and
forms  and  (ii)  material  information  required  to  be  disclosed  in  our  reports  filed  under  the  Exchange  Act  is  accumulated  and
communicated to our management, including our CEO and CFO, as appropriate, to allow for accurate and timely decisions regarding
required disclosure.

Disclosure  controls  and  procedures  were  not  effective  due  primarily  to  material  weaknesses  in  the  Company’s  internal  control  of
financial reporting as discussed below.

Internal control over financial reporting

Management’s annual report on internal control over financial reporting

The  management  of  USAC  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  This
internal  control  system  has  been  designed  to  provide  reasonable  assurance  to  our  management  and  Board  of  Directors  regarding  the
preparation and fair presentation of our published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be
effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The management of USAC has assessed the effectiveness of our internal control over financial reporting as of December 31, 2020. To
make this assessment, we used the criteria for effective internal control over financial reporting described in Internal Control-Integrated
Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

As  a  result  of  our  assessment,  we  concluded  that  we  have  material  weaknesses  in  our  internal  control  over  financial  reporting  as  of
December 31, 2021. These weaknesses are as follows:

·

·

·

Inadequate design of internal control over the preparation of the financial statements and financial reporting processes;

Inadequate  monitoring  of  internal  controls  over  significant  accounts  and  processes  including  controls  associated  with
domestic and Mexican subsidiary operations and the period-end financial reporting process; and

The  absence  of  proper  segregation  of  duties  within  significant  processes  and  ineffective  controls  over  management
oversight, including antifraud programs and controls.

We are aware of these material weaknesses and will develop procedures to ensure that independent review of material transactions is
performed. The chief financial officer will develop internal control measures to mitigate the inadequate documentation of controls and
the  monitoring  of  internal  controls  over  significant  accounts  and  processes  including  controls  associated  with  the  period-ending

reporting processes, and to mitigate the segregation of duties within significant accounts and processes and the absence of controls over
management oversight, including antifraud programs and controls.

We plan to consult with independent experts when complex transactions are entered into.

Because these material weaknesses exist, management has concluded that our internal control over financial reporting as of December
31, 2021, is ineffective.

Changes in internal control over financial reporting

There were no changes in internal control over financial reporting for the quarter ended December 31, 2021.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the board of directors of United States Antimony Corporation

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  United  States  Antimony  Corporation  (the  “Company”)  as  of
December 31, 2021 and 2020, the related consolidated statements of operations, of changes in stockholders’ equity and of cash flows
for  each  of  the  years  then  ended,  and  the  related  notes  (collectively  referred  to  as  the  “financial  statements”).  In  our  opinion,  the
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020,
and the results of its operations and its cash flows for each of the years then ended, in conformity with accounting principles generally
accepted in the United States of America.

Basis for Opinion

These  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the
Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting
Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the
U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of
our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing
an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error
or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such  procedures  included  examining,  on  a  test  basis,  evidence
regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used
and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe
that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

Evaluation of properties, plants, and equipment for impairment triggering events 

As discussed in Note 2 to the consolidated financial statements, the Company evaluates properties, plants, and equipment (“PPE”) to
identify  events  or  changes  in  circumstances,  referred  to  as  triggering  events,  that  indicate  the  carrying  value  of  PPE  may  not  be
recoverable. An impairment loss is recorded in the period in which it is determined that the carrying amount of PPE is not recoverable.
As of December 31, 2021, the carrying value of properties, plants and equipment, net was approximately $11.1 million.

We  identified  the  evaluation  of  PPE  for  impairment  triggering  events  as  a  critical  audit  matter. A  high  degree  of  subjective  auditor
judgment  was  required  in  evaluating  the  Company’s  assessment  of  current  operations,  financial  results  and  historical  projections,
current industry and market conditions, and relevant industry data for impairment indicators.

The following are the primary procedures we performed to address this critical audit matter.

·

We evaluated the Company’s process of identifying and assessing potential triggering events, including the Company’s
assessment of current operations, financial results and historical projections, current industry and market conditions, and
relevant industry data.

·

We evaluated the Company’s identification and assessment of triggering events by evaluating current period operations,
financial results and historical projections, including current industry and market considerations.

We compared relevant industry data used by the Company to external sources, including market index data.

·

We evaluated the Company’s analysis over the factors and considered whether the Company omitted any significant internal
or external elements in its evaluation.

United States Antimony Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2021 and 2020

1. Background of Company and Basis of Presentation

AGAU Mines, Inc., predecessor of United States Antimony Corporation (“USAC” or “the Company”), was incorporated in June
1968  as  a  Delaware  corporation  to  mine  gold  and  silver.  USAC  was  incorporated  in  Montana  in  January  1970  to  mine  and
produce  antimony  products.  In  June  1973,  AGAU  Mines,  Inc.  was  merged  into  USAC.  In  December  1983,  the  Company
suspended its antimony mining operations when it became possible to purchase antimony raw materials more economically from
foreign sources. The principal business of the Company has been the production and sale of antimony products.

During 2000, the Company formed a 75% owned subsidiary, Bear River Zeolite Company (“BRZ”), to mine and market zeolite
and zeolite products from a mineral deposit in southeastern Idaho. In 2001, an operating plant was constructed at the zeolite site
and zeolite production and sales commenced. During 2002, the Company acquired the remaining 25% of BRZ and continued to
produce and sell zeolite products.

During  2005,  the  Company  formed  a  100%  owned  subsidiary,  Antimonio  de  Mexico  S.A.  de  C.V.  (“AM”),  to  explore  and
develop potential antimony properties in Mexico.

During 2006, the Company acquired 100% ownership in United States Antimony, Mexico S.A. de C.V. (“USAMSA”), which
became a wholly-owned subsidiary of the Company.

In 2018, the Company acquired 100% ownership in Stibnite Holding Company US Inc. (previously Lanxess Holding Company
US Inc.), Antimony Mining and Milling US LLC (previously Lanxess Laurel US LLC), a Delaware limited liability company
and Lanxess Laurel de Mexico, S.A. de C.V (“Lanxess Laurel Mexico”), a Mexico corporation, both of which became a wholly-
owned subsidiary of the Company.

COVID-19 Coronavirus Pandemic Response and Impact

Following the outbreak of the COVID-19 coronavirus global pandemic (“COVID-19”) in early 2020, in March 2020 the U.S.
Centers  for  Disease  Control  issued  guidelines  to  mitigate  the  spread  and  health  consequences  of  COVID-19.  The  Company
implemented  changes  to  its  operations  and  business  practices  to  follow  the  guidelines  and  minimize  physical  interaction,
including  using  technology  to  allow  employees  to  work  from  home  when  possible  and  altering  production  procedures  and
schedules,  asset  maintenance,  and  limiting  discretionary  spending. We  continue  to  monitor  guidance  from  federal,  state,  local
and foreign governments and public health authorities and may need to take additional actions based on their recommendations.
The extent of the impact of COVID-19 on our business and financial results will also depend on future developments, including
the duration and spread of the outbreak and the success of the current vaccination programs, all of which are uncertain.

2. Summary of Significant Accounting Policies  

Principles of Consolidation

The Company’s consolidated financial statements include the accounts of its wholly-owned subsidiaries BRZ, USAMSA, AM,
Stibnite Holding Company US Inc., and Antimony Mining and Milling US LLC. All intercompany balances and transactions are
eliminated in consolidation.

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of
America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Significant and critical estimates include property, plant and equipment depreciation and
potential  impairment,  metal  content  of  mineral  resources,  accounts  receivable  allowance  for  uncollectible  accounts,  net
realizable  value  of  inventories,  deferred  income  taxes,  income  taxes  payable,  environmental  remediation  liabilities  and  asset
retirement obligations. Actual results could differ from those estimates.

United States Antimony Corporation and Subsidiaries  
Notes to Consolidated Financial Statements 
December 31, 2021 and 2020

Cash and Cash Equivalents

The Company considers cash in banks and investments with original maturities of three months or less when purchased to be
cash equivalents. At December 31, 2021 and 2020, restricted cash for reclamation bonds of $57,281 and $57,275 are included in
cash and cash equivalents and restricted cash balances on the statements of cash flows

            Restricted Cash

Restricted  cash  at  December  31,  2021  and  2020  consists  of  cash  held  for  reclamation  performance  bonds  and  is  held  in
certificates of deposit with financial institutions.

Accounts Receivable

Accounts  receivable  are  stated  at  the  amount  that  management  expects  to  collect  from  outstanding  balances.  Management
provides for probable uncollectible amounts through an allowance for doubtful accounts. Changes to the allowance for doubtful
accounts  are  based  on  management’s  judgment,  considering  historical  write-offs,  collections  and  current  credit  conditions.
Balances which remain outstanding after management has used reasonable collection efforts are written off through a charge to
the  allowance  for  doubtful  accounts  and  a  credit  to  the  applicable  accounts  receivable.  Payments  received  on  receivables
subsequent to being written off are considered a bad debt recovery.

            Inventories

Inventories at December 31, 2021 and 2020 consisted of finished antimony products, antimony metal, antimony concentrates,
antimony ore, and finished zeolite products, and are stated at the lower of first-in, first-out weighted average cost or estimated
net  realizable  value.  Finished  antimony  products,  antimony  metal  and  finished  zeolite  products  costs  include  raw  materials,
direct labor and processing facility overhead costs and freight allocated based on production quantity. Stockpiled ore is carried at
the lower of average cost or net realizable value. Since the Company’s antimony inventory is a commodity with a sales value
that  is  subject  to  world  prices  for  antimony  that  are  beyond  the  Company’s  control,  a  significant  change  in  the  world  market
price of antimony could have a significant effect on the net realizable value of inventories. The Company periodically reviews its
inventories to identify excess and obsolete inventories and to estimate reserves for obsolete inventories as necessary to reflect
inventories at net realizable value.

Translations of Foreign Currencies

All amounts in the financial statements are presented in U.S. dollars, which is the functional currency for all of the Company’s
operations. Foreign translation gains and losses relating to Mexican subsidiaries are recognized as foreign exchange gain or loss
in the consolidated statement of operations.

            Properties, Plants and Equipment

Properties, plants and equipment are stated at historical cost and are depreciated using the straight-line method over estimated
useful  lives  of  two  to  thirty  years. Vehicles  and  office  equipment  are  stated  at  cost  and  are  depreciated  using  the  straight-line
method  over  estimated  useful  lives  of  three  to  twelve  years.  Maintenance  and  repairs  are  charged  to  operations  as  incurred.
Betterments of a major nature are capitalized. Expenditures for new property, plant, equipment, and improvements that extend
the  useful  life  or  functionality  of  the  asset  are  capitalized. When  assets  are  retired  or  sold,  the  costs  and  related  accumulated
depreciation are eliminated from the accounts and any resulting gain or loss is reflected in operations.

The  costs  to  obtain  the  legal  right  to  explore,  extract  and  retain  at  least  a  portion  of  the  benefits  from  mineral  deposits  are
capitalized as mineral rights in the year of acquisition. These capitalized costs are amortized on the statement of operations using
the straight-line method over the expected life of the mineral deposit when placed into production. Mineral rights are assessed
for impairment when facts and circumstances indicate that the potential for impairment exists. Mineral rights are subject to write
down in the period the property is abandoned. Mineral properties are amortized over the estimated economic life of the mineral
resource using the straight-line method, based upon estimated lives of the properties, or the units-of-production method, based
upon estimated units of mineral resource.

Notes to Consolidated Financial Statements
December 31, 2021 and 2020

Impairment of Long-lived Assets

Management reviews and evaluates the net carrying value of its long-lived assets for impairment upon the occurrence of events
or changes in circumstances that indicate that the related carrying amounts may not be recoverable. A test for recoverability is
performed based on the estimated undiscounted future cash flows that will be generated from operations at each property and the
estimated salvage value of asset. Although management has made what it believes to be a reasonable estimate of factors based
on current conditions and information, assumptions underlying future cash flows, which includes the estimated value of assets,
are subject to significant risks and uncertainties. Estimates of undiscounted future cash flows are dependent upon, among other
factors,  estimates  of:  (i)  product  and  metals  to  be  recovered  from  identified  mineralization  and  other  resources  (ii)  future
production and capital costs, (iii) estimated
selling prices (considering current, historical, and future prices) over the estimated remaining life of the asset and (iv) market
values of property, if appropriate. It is possible that changes could occur in the near term that could adversely affect the estimate
of future cash flows to be generated from operating properties. If estimated undiscounted cash flows are less than the carrying
value of an asset, an impairment loss is recognized for the difference between the carrying value and fair value of the asset.

Exploration and Development

The  Company  expenses  exploration  costs  as  such  in  the  period  they  occur.  The  mine  development  stage  begins  once  the
Company has determined an ore body can be economically developed. Expenditures incurred during the development stage are
capitalized as deferred development costs. Costs to improve, alter, or rehabilitate primary development assets which appreciably
extend the life, increase capacity, or improve the efficiency or safety of such assets are also capitalized. The development stage
ends when the production stage of reserves begins. Deferred development costs are amortized over the estimated economic life
of the mineral resource using the straight-line method, based upon estimated lives of the properties, or the units-of-production
method, based upon estimated units of mineral resource.

Asset Retirement Obligations and Reclamation Costs

All of the Company’s mining operations are subject to reclamation and remediation requirements. Minimum standards for mine
reclamation have been established by various governmental agencies. Costs are estimated based primarily upon environmental
and  regulatory  requirements  and  are  accrued.  The  liability  for  reclamation  is  classified  as  current  or  noncurrent  based  on  the
expected timing of expenditures. Reclamation differs from an asset retirement obligation in that no associated asset is recorded
in the case of reclamation liabilities.

It  is  reasonably  possible  that  because  of  uncertainties  associated  with  defining  the  nature  and  extent  of  environmental
contamination, application of laws and regulations by regulatory authorities, and changes in remediation technology, the ultimate
cost of remediation and reclamation could change in the future. The Company continually reviews its accrued liabilities for such
remediation  and  reclamation  costs  as  evidence  becomes  available  indicating  that  its  remediation  and  reclamation  liability  has
changed.

The Company records the fair value of an asset retirement obligation as a liability in the period in which the Company incurs a
legal obligation for the retirement of long-lived assets if it is probable that such costs will be incurred and they are reasonably
estimable. A  corresponding  asset  is  also  recorded  and  depreciated  over  the  life  of  the  assets  on  a  straight-line  basis. After  the
initial measurement of the asset retirement obligation, the liability will be adjusted to reflect changes in the estimated future cash
flows underlying the obligation. Determination of any amounts included in determination of fair value is based upon numerous
estimates and assumptions, including future retirement costs, future inflation rates, and the Company’s credit-adjusted risk-free
interest rates.

United States Antimony Corporation and Subsidiaries
Notes to Consolidated Financial Statements

Revenue Recognition

Products consist of the following:

·
·
·

Antimony: includes antimony oxide, sodium antimonate, antimony trisulfide, and antimony metal
Zeolite: includes coarse and fine zeolite crushed in various sizes
Precious Metals: includes unrefined and refined gold and silver

For  antimony  and  zeolite  products,  revenue  is  recognized  upon  the  completion  of  the  performance  obligation  which  is  met
when the transaction price can be reasonably estimated and revenue is recognized generally at the time when risk is transferred.
The  Company  has  determined  the  performance  obligation  is  met  and  title  is  transferred  either  upon  shipment  from  the
Company’s  warehouse  locations  or  upon  receipt  by  the  customer  as  specified  in  individual  sales  orders.  The  performance
obligation is met because at that time, 1) legal title is transferred to the customer, 2) the customer has accepted the product and
obtained  the  ability  to  realize  all  of  the  benefits  from  the  product,  3)  the  customer  has  the  significant  risks  and  rewards  of
ownership to it, 4) it is very unlikely product will be rejected by the customer upon physical receipt, and 5) the Company has
the right to payment for the product. Shipping costs related to the sales of antimony and zeolite products are recorded to cost of
sales as incurred. For zeolite products, royalty expense due a third party by the Company is also recorded to cost of sales upon
sale in accordance with terms of underlying royalty agreements.

For sales of precious metals, the performance obligation is met, the transaction price is known, and revenue is recognized at the
time of transfer of control of the agreed-upon metal quantities to the customer. Refining and shipping costs related to sales of
precious metals are recorded to cost of sales as incurred.

The Company has determined that its contracts do not include a significant financing component. Prepayments, which are not
common, received from customers prior to the time that products are processed and shipped, are recorded as deferred revenue.
For antimony and zeolite sales contracts, the Company may factor certain receivables and receive final payment within 30 days
of the performance obligation being met. For antimony and zeolite receivables not factored, the Company typically receives
payment within 10 days. For precious metals sales, a provisional payment of 75% is typically received within 45 days of the
date the product is delivered to the customer. After an exchange of assays, a final payment is normally received within 90 days
of product delivery.

Common Stock Issued for Consideration Other than Cash

All  transactions  in  which  goods  or  services  are  received  for  the  issuance  of  shares  of  the  Company’s  common  stock  are
accounted for based on the fair value of the common stock issued.

Income Taxes

Income  taxes  are  accounted  for  under  the  liability  method.  Under  this  method,  deferred  income  tax  liabilities  or  assets  are
determined at the end of each period using the tax rate expected to be in effect when the taxes are actually paid or recovered. A
valuation allowance is recognized on deferred tax assets when it is more likely than not that some or all of these deferred tax
assets will not be realized.

The Company applies generally accepted accounting principles for recognition of uncertainty in income taxes and prescribing a
recognition threshold and measurement attribute for the recognition and measurement of a tax position taken or expected to be
taken in a tax return.

Income (Loss) Per Common Share

Basic earnings per share is calculated by dividing net income (loss) available to common stockholders by the weighted average
number  of  common  shares  outstanding  during  the  period.  Diluted  earnings  per  share  is  calculated  based  on  the  weighted
average  number  of  common  shares  outstanding  during  the  period  plus  the  effect  of  potentially  dilutive  common  stock
equivalents, including stock options, warrants to purchase the Company’s common stock, and convertible preferred stock. For
the years ended December 31, 2020 and 2020, potentially dilutive common stock equivalents not included in the calculation of
diluted earnings per share because they were anti-dilutive are as follows:

The  Company’s  financial  instruments  include  cash  and  cash  equivalents,  certificates  of  deposits,  and  restricted  cash.  The
carrying value of these instruments approximates fair value based on their contractual terms.

Fair Value Measurements

When  required  to  measure  assets  or  liabilities  at  fair  value,  the  Company  uses  a  fair  value  hierarchy  based  on  the  level  of
independent, objective evidence surrounding the inputs used. The Company determines the level within the fair value hierarchy
in which the fair value measurements in their entirety fall. The categorization within the fair value hierarchy is based upon the
lowest level of input that is significant to the fair value measurement. Level 1uses quoted prices in active markets for identical
assets  or  liabilities,  Level  2  uses  significant  other  observable  inputs,  and  Level  3  uses  significant  unobservable  inputs.  The
amount of the total gains or losses for the period are included in earnings that are attributable to the change in unrealized gains
or losses relating to those assets and liabilities still held at the reporting date.The Company has no financial assets or liabilities
that are adjusted to fair value on a recurring basis.

Contingencies

In  determining  accruals  and  disclosures  with  respect  to  loss  contingencies,  the  Company  evaluates  such  accruals  and
contingencies  for  each  reporting  period.  Estimated  losses  from  loss  contingencies  are  accrued  by  a  charge  to  income  when
information available prior to issuance of the financial statements indicates that it is probable that a liability could be incurred
and  the  amount  of  the  loss  can  be  reasonably  estimated.  Legal  expenses  associated  with  the  contingency  are  expensed  as
incurred.  If  a  loss  contingency  is  not  probable  or  reasonably  estimable,  disclosure  of  the  loss  contingency  is  made  in  the
financial statements when it is at least reasonably possible that a material loss could be incurred.

Recent Accounting Pronouncements

In  December  2019,  the  Financial Accounting  Standards  Board  (“FASB”)  issued Accounting  Standards  Update  (“ASU”)  No.
2019-12 Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The update contains a number of provisions
intended to simplify the accounting for income taxes. The update was adopted as of January 1, 2021, and its adoption did not
have a material impact on the Company’s consolidated financial statements.

Accounting  standards  that  have  been  issued  or  proposed  by  FASB  that  do  not  require  adoption  until  a  future  date  are  not
expected to have a material impact on the financial statements upon adoption.

Common Stock Warrants

The  Company’s  Board  of  Directors  has  the  authority  to  issue  stock  warrants  for  the  purchase  of  preferred  or  unregistered
common stock to directors and employees of the Company.

At  December  31,  2019,  warrants  for  purchase  of  250,000  shares  of  the  Company’s  common  stock  for  $0.25  per  share  were
outstanding. These warrants were owned by the Company’s previous President and Chairman, John Lawrence. The warrants
were exercised on March 18, 2020 in exchange for a reduction in an amount payable to Mr. Lawrence.

In July 2020, warrants for purchase of 5,742,858 shares of the Company’s common stock were sold with shares of common
stock. The warrants have an exercise price of $0.46 per share and expire in 2025. The warrants can be exercised on a cashless
basis. The warrants contain a repricing provision whereby if the Company raises at least $6,000,000 in gross proceeds from the
sale of its common stock at an effective price per share less than the warrants’ exercise price, the exercise price of the warrants
will be repriced to the lower price.

In  February  2021,  concurrent  with  sale  of  common  stock,  the  Company  issued  warrants  to  purchase  7,650,000  shares  of
common stock at an exercise price of $0.85 per share. The warrants are initially exercisable six months following issuance and

payable  if  and  when  declared  by  the  Board  of  Directors.  During  each  of  the  years  ended  December  31,  2021  and  2020  the
Company recognized $7,500 in Series B preferred stock dividend. In the event of dissolution or liquidation of the Company,
the preferential amount payable to Series B preferred stockholders is $1.00 per share plus dividends in arrears. No dividends
have been declared or paid with respect to the Series B preferred stock. The Series B Preferred stock is no longer convertible to
shares of the Company’s common stock. At December 31, 2021 and 2020, cumulative dividends in arrears on the outstanding
Series B shares were $202,500 and $195,000, respectively.

Series C

During 2000, the Board established a Series C preferred stock. The Series C preferred stock has preference over the Company’s
common stock and has voting rights equal to that number of shares outstanding, but no conversion or dividend rights. In the
event of dissolution or liquidation of the Company, the preferential amount payable to Series C preferred stockholders is $0.55
per share.

Series D

During 2002, the Board established a Series D preferred stock, authorizing the issuance of up to 2,500,000 shares. The Series D
preferred  stock  has  preference  over  the  Company’s  common  stock  but  is  subordinate  to  the  liquidation  preferences  of  the
holders of the Company’s outstanding Series A, Series B and Series C preferred stock. Series D preferred stock carries voting
rights and is entitled to annual dividends of $0.0235 per share. The dividends are cumulative and payable after payment and
satisfaction of the Series A, B and C preferred stock dividends. No dividends have been declared or paid with respect to the
Series D preferred stock.

During the year ended December 31, 2021, 58,333 shares of Series D preferred stock was converted to 58,333 shares of the
Company’s common stock. As part of this conversion, the shareholder was issued 64,184 shares of the Company’s common
stock to satisfy cumulative dividends associated with the preferred shares.

At December 31, 2021 and 2020, the cumulative dividends in arrears on the outstanding Series D shares were $747,952 and
$707,258, respectively, payable if and when declared by the Board of Directors.

In the event of dissolution or liquidation of the Company, the preferential amount payable to Series D preferred stockholders is
$2.50 per share. At December 31, 2021 and 2020, the liquidation preference for Series D preferred stock was $4,979,632 and
$5,084,770, respectively. Holders of the Series D preferred stock have the right, subject to the availability of authorized but
unissued  common  stock,  to  convert  their  shares  into  shares  of  the  Company’s  common  stock  on  a  one-to-one  basis  without
payment  of  additional  consideration  and  are  not  redeemable  unless  by  mutual  consent.  The  majority  of  Series  D  preferred
shares are held by the estate of John Lawrence, the previous President and Chairman of the Company.

United States Antimony Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2021 and 2020

10. 2000 Stock Plan

In  January  2000,  the  Company’s  Board  of  Directors  resolved  to  create  the  United  States Antimony  Corporation  2000  Stock
Plan  (“the  Plan”).  The  purpose  of  the  Plan  is  to  attract  and  retain  the  best  available  personnel  for  positions  of  substantial
responsibility  and  to  provide  additional  incentive  to  employees,  directors  and  consultants  to  promote  the  success  of  the
Company’s  business. The  maximum  number  of  shares  of  common  stock  or  options  to  purchase  common  stock  that  may  be
issued pursuant to the Plan is 500,000. At December 31, 2021 and 2020, 300,000 shares of the Company’s common stock had
been previously issued under the Plan. There were no issuances under the Plan during 2021 and 2020.

11. Income and Other Taxes

During the year ended December 31, 2021 and 2020, the Company recognized no income tax benefit (provision).

Domestic and foreign components of net loss from operations before income taxes for the years ended December 31, 2021 and
2020, are as follows:

The income tax benefit differs from the amount of income tax determined by applying the U.S. federal income tax rate to pre-
tax net loss for the years ended December 31, 2021 and 2020 due to the following:

At December 31, 2020 and 2019, the Company had net deferred tax assets as follows:

United States Antimony Corporation and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2021 and 2020

At  December  31,  2021  and  2020,  the  Company  had  deferred  tax  assets  arising  principally  from  net  operating  loss  carry
forwards  for  income  tax  purposes.  As  management  cannot  determine  that  it  is  more  likely  than  not  the  benefit  of  the  net
deferred  tax  asset  will  be  realized,  a  valuation  allowance  equal  to  100%  of  the  net  deferred  tax  asset  has  been  recorded  at
December 31, 2021 and 2020.

At December 31, 2021, the Company has federal net operating loss (“NOL”) carry forwards of approximately $290,000 that
expire at various dates between 2036 and 2037. In addition, the Company has federal NOL carry forwards of $666,000 that will
never expire but utilization of which is limited to 80% of taxable income in any future year. The Company has Montana state
NOL carry forwards of approximately $2.3 million which expire between 2022 and 2026, and Idaho state NOL carry forwards
of  approximately  $1.4  million,  which  expire  between  2033  and  2035.  The  Company  has  approximately  $5.2  million  of
Mexican NOL carry forwards which expire between 2025 and 2030.

In 2018, the Company acquired two subsidiaries have net operating loss carryforwards in Mexico of approximately $800,000.
Due to limitations, it is likely that a portion of this carryforward will not be available to offset the Company’s future taxable
income in Mexico.

During the years ended December 31, 2021 and 2020, there were no material uncertain tax positions taken by the Company.
The Company’s United States income tax filings are subject to examination for the years 2019 through 2021, and 2018 through
2021 in Mexico. The Company charges penalties on assessments to general and administrative expense and charges interest to
interest expense.

Mexican Tax Assessment

In 2015, the Mexican tax authority (“SAT”) initiated an audit of the USAMSA’s 2013 income tax return. In October 2016, as a
result  of  its  audit,  SAT  assessed  the  Company  $13.8  million  pesos,  which  was  approximately  $666,400  in  U.S.  Dollars
(“USD”)  as  of  December  31,  2016.  SAT’s  assessment  was  based  on  the  disallowance  of  specific  costs  that  the  Company
deducted  on  the  2013  USAMSA  income  tax  return.  The  assessment  was  settled  in  2018  with  no  assessment  against  the
Company.

In  early  2019,  the  Company  was  notified  that  SAT  re-opened  its  assessment  of  USAMSA’s  2013  income  tax  return  and,  in
November 2019, SAT assessed the Company $16.3 million pesos, which was approximately $795,000 USD as of December
31, 2021.

Management reviewed the 2019 assessment notice from SAT and, similar to the earlier assessment, believes the findings have
no merit. An appeal was filed by the Company in November 2019 suspending SAT from taking immediate action regarding the
assessment. The Company posted a guarantee of the amount in March 2020 as is required under the appeal process. In August
2020, the Company filed a lawsuit against SAT for resolution of the process and, in December 2020, filed closing arguments.
Management expects the appeal process to continue through 2022.

At December 31, 2021, management assessed the possible outcomes for this tax audit and believes, based on discussions with
its tax attorney in Mexico, that the most likely outcome will be that the Company will be successful in its appeal resulting in no
tax due. Management determined that no amount should be accrued at December 31, 2021 or December 31, 2020 relating to
this  potential  tax  liability.  There  can  be  no  assurance  that  the  Company’s  ultimate  liability,  if  any,  will  not  have  a  material
adverse effect on the Company’s results of operations or financial position.

If an issue addressed during the SAT audit is resolved in a manner inconsistent with management expectations, the Company
will adjust its current net operating loss carryforward, or accrue penalties, interest, and tax associated with the assessment.

Other Taxes

In 2016, USAMSA imported coal from the United States to its smelter in Mexico to process Australian concentrates associated
with the Hillgrove agreement (Note 9). At that time, the Company applied for and was granted a Maquiladora (IMMEX), in
accordance  with  a  Manufacturing  and  Export  Services  Industry  program  offered  by  the  Mexican  government  to  attract  and
promote foreign investment in Mexico. With the IMMEX, all imported goods to Mexico that are also exported in altered form
are exempt from the requirement of paying the 16% tax (IVA). The Company did not pay IVA on any of the imported coal used
to process the Australian concentrates. In 2020, the Company was informed by the SAT that it owed the 16% IVA money for all
the coal imported for the processing of the Australian concentrates. Additionally, there were penalties and fees that SAT added
to the total amount. In late 2020, the Company filed a motion before the Taxpayer’s Defense Agency (PRODECON), but the
motion was denied. To avoid exorbitant penalties, the Company elected to pay the assessed amount in early 2021. For the year
ended  December  31,  2020,  the  Company  recognized  an  export  tax  expense  of  $1,120,730  and  accrued  a  liability  for  this
assessment. The amount was paid in early 2021.

12. Related-Party Transactions

John Lawrence, the Company’s previous Chief Executive Officer and Chairman of the Board of Directors, rented equipment to
the Company and charged the Company for lodging and meals provided to consultants, customers and other parties by an entity
that  Mr.  Lawrence  owned.  The  amount  due  to  Mr.  Lawrence  as  of  December  31,  2020  was  $171,017.  During  2021,  the
Company paid the full amount of $171,017 to John Lawrence’s estate for reimbursement of these expenses. Expenses paid to
Mr. Lawrence for the year ended December 31, 2020 were $1,533. During 2020, an advance of $56,215 due to John Lawrence
was satisfied with the exercise of a warrant held by Mr. Lawrence for 250,000 shares of common stock at an exercise price of
$0.25 or $62,500.

During the year ended December 31, 2021, Russ Lawrence, President and Director, incurred expenses of $24,510 and charged
the Company for lodging and meals provided to visiting Board of Directors by an entity that Russ Lawrence owns. During the
year ended December 31, 2021, the Company paid Russ Lawrence $27,290, leaving a balance due of $1,846 which is included
in accounts payable on the balance sheet.

13. Commitments and Contingencies

From  time  to  time,  the  Company  is  assessed  fines  and  penalties  by  the  Mine  Safety  and  Health Administration  (“MSHA”).
Using appropriate regulatory channels, management may contest these proposed assessments. At December 31, 2021 and 2020,
the Company had accrued liabilities of $Nil and $246, respectively, relating to such assessments.

The Company pays various royalties on the sale of zeolite products. On a combined basis, royalties vary from 8%-13%. During
the year ended December 31, 2021 and 2020, the Company had royalty expense of $262,861 and $224,875, respectively. At
December  31,  2021  and  2020,  the  Company  had  accrued  royalties  payable  of  $346,242  and  $434,981,  respectively.  The
Company is currently in negotiations with certain royalty holders to modify the terms of the agreements.

14. Business Segments

The Company is currently organized and managed by four segments, which represent the three operating units: United States
antimony, Mexican antimony, United States zeolite, and precious metals. The Company’s other operating costs include general
and administrative expenses, freight and delivery, and other non-production related costs. Other income and expense consist
primarily of non-operating income and interest expense.

The Madero smelter and Puerto Blanco mill at the Company’s Mexico operation brings antimony up to a finished product or an
intermediate stage, which is then either shipped directly to customers or to the United States operation for finishing and sales at
the  Thompson  Falls,  Montana  plant.  The  Zeolite  operation  produces  zeolite  near  Preston,  Idaho. Almost  all  of  the  sales  of
products  from  the  United  States  antimony  and  zeolite  operations  are  to  customers  in  the  United  States.  Precious  metal
recovered from the antimony process in the United States and Mexico is typically sold to customers in the United States and
Canada.

Segment disclosures regarding sales to major customers and for property, plant, and equipment are located in Notes 3 and 6,
respectively.
