United States Antimony
Corporation (USAC) NYSE (uamy) is a rapidly growing
natural resource company that is increasing its raw
material supply of antimony from properties in Mexico
and third parties around the world. USAC has produced
various antimony products since 1969 and is a fully
integrated mining, transportation, milling, smelting,
and selling company. USAC operates the only significant
antimony smelter in the United States and it is in a
"sold out" condition. The Company has proven experience
in underground and open pit mining, flotation and
gravimetric milling, crushing and screening, dry
grinding, cyanide leaching, precious metal refining,
pyro-metallurgy, and marketing.
Operations include a smelter and a precious metal
refinery in Montana, and a smelter and three mills in
Mexico. Three Mexican properties supply direct shipping
ore (DSO) or mill feed for the Mexican operations. The
Los Juarez property and mill at Puerto Blanco are being
permitted to start gold and silver production that will
supplement the antimony values and identify the Company
as a "precious metal producer."
USAC owns 100% of the Bear River Zeolite, Corp. mine in
southeast Idaho that management regards as one of the
best zeolite properties in the world due to its high
cation exchange capacity, low sodium content, hardness,
uniformity, high potassium content, large surface area,
and low clay and impurity content.
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
In our existing operations in
Montana, we produce antimony oxide, sodium antimonate, 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. Sodium antimonate is
primarily used as a fining agent (degasser) for glass in cathode ray
tubes and as a flame retardant. We also sell antimony metal for use in
bearings, storage batteries and ordnance.
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 two of the three
operating antimony smelters in North and Central America.
We are the major domestic
producer of antimony products.
We can ship on short notice to
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.
As a vertically integrated
company, we will have more control over our raw material costs.
We own 100% of Bear River Zeolite Company,
(BRZ an Idaho corporation) that was incorporated on June 1, 2000. B
We have no "proven reserves" or "probable
reserves" of zeolite, as these terms are defined by the Securities and
"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 depositsí 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.
Precious Metals (Gold and Silver)
USAC has reported progress on the gold and silver leach plant in
Guanajuato, Mexico for the Los Juarez property.
The shakedown of the cyanide plant at Puerto Blanco has progressed as
expected, and we look forward to becoming a gold and silver mining
