NYSE MKT (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 marketing 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. USAC has developed
proprietary technology to smelt a variety of raw materials and recover
impurities such as lead, arsenic, bismuth, mercury, selenium, silver, and gold.
supplies more than 90 percent of all the antimony in the world, and their
resources are being depleted.
Operations include a smelter and a precious metal refinery in Montana, and a
smelter and three mills in Mexico. A larger 400 ton mill is being installed 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. The deposit can be mined
and processed cheaper than other deposits because there is little internal or
external overburden, it is more than 800 feet thick, and it is very homogeneous.
BRZ zeolite has hundreds of applications as an “environmentally friendly”
