Summary:
The main ore body at the West mine is located 800 to 1,100 feet below the surface. After extraction by mining equipment adapted from the coal industry, the ore, which contains primarily sylvite and salt.
Summary:
Ore extraction and conveyance to the surface is similar for both our East Mine and West Mine.
Potash was mined from underground bedded deposits using continuous mining machines with shuttle car haulage from the face.

Summary:
The West Mine consists of a mine and mill originally built in 1931.
The surface facility uses a flotation process to separate the sylvite from the salt. The refined sylvite is called Muriate of Potash or potash for short and is transported to the North Facility where it is compacted and processed into a granular form suitable for agricultural applications. The granular product is stored in warehouses until it is sold into the wholesale fertilizer market.
The West mine has a current estimated productive capacity of approximately 400,000 tons of red potash annually.
