BRZ GEOLOGY



Aerial view of BRZ pit near Preston, Idaho

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 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 and on more than 700 acres. The current pit covers more than 3 acres. Within the pit, the zeolite is remarkably homogeneous. 

Despite the apparent huge size of the deposit, the Company claims no reserves.
