"Zeolite" refers to a group of minerals that are basically hydrated calcium potassium sodium aluminosilicates in which the water is held in cavities in the lattice.

The lattices are negatively charged and they loosely hold cations such as calcium, sodium, ammonium, and potassium; and also water.

Their ability to exchange one cation for another is known as their "cation-exchange capacity" or "CEC". Cation-exchange capacity is a measure of the number of cations per unit weight available for exchange, usually expressed as milliequivalents per 100 grams of material

Zeolites can be synthetically engineered and produced for such applications as water softening, detergents, cation removal, and for a wide variety of oil refining applications. The cost of these synthetic zeolites range up to $100.00 per pound or $2,000,000.00 per ton.

Bear River Zeolite (BRZ) is a natural zeolite and one of its huge advantages is that it is sold for approximately $.10 per pound, or $200.00 per ton.


Zeolites are also referred to as "molecular sieves", because the channel ways within the crystalline structure are extremely small and they can be used to separate large molecules from smaller molecules.

The reader is referred to a paper "La roca magica: Uses of natural zeolites in agriculture and industry"  by the late Fredrick A. Mumpton.




Bear River Zeolite Company (BRZ™) is a wholly owned subsidiary of United States Antimony Corporation (USAC) which is traded on NYSE MKT as UAM, of Thompson Falls, Montana. (



The Bear River Zeolite deposit is located in the southeast corner of Idaho approximately 7 road miles east of Preston, Idaho; 34 road miles north of Logan, Utah; 70 road miles south of Pocatello, Idaho; and 100 road miles north of Salt Lake City, Utah. It is convenient to two railroad lines and major interstate highways.
