Perlite deposit is large over five hundred feet in height.

Permited Perlite extraction of 50,000 tons per year, can be increased for example to 250,000 tons per year.

Uses, construction applications, horticultural applications, and industrial applications, road base.

For sale - approx. 340 acres of land containing several permitted patented placer mining claims.

Mining is conducted using conventional open pit practices. Overburden is removed by a bulldozer exposing the Perlite. The perlite is placed into gravity feeding device to the mill. The flow of perlite is controlled by vibrating plate, which feeds a primary jaw crusher. This is the start of the milling process.

The primary jaw crusher reduces the perlite rock to a manageable level and the product moves by conveyor belt to a secondary cone crusher. Here there is a recycle system in place to return any oversize material for re-crushing. Next, the crushed perlite is conveyed by short belt to a long, rotary dryer. This dryer removes the surface moisture from perlite and allows for proper screening. After the dryer, the perlite is conveyed to the top of the mill starting the screening process.

In 1998 the mill was renovated for increased efficiency & productivity. The mill includes two separate circuits, running side by side over three levels of screening decks. Perlite flows over & through the screens, separating into the various grades sold. The screening levels are well above ground level, allowing the screened perlite to be diverted into several different storage silos & bunkers. Trucks can pull underneath these bunkers to load by gravity.
Uses construction, industrial, light weight concrete, light weight block material, horticulture, rail ballast, road base.
This Perlite can then be sent to the Port of Long Beach, Ca. and shipped World Wide!
