Tolsa USA, Inc.

Tolsa completed the purchase of assets and mining claims of Rock Springs Minerals and US Bentonite in late December of 2014. Since December, they’ve run preliminary trials, staffed the facility and are in the process of initial production runs. Tosla has invested millions of dollars since the acquisition and has more scheduled and budgeted for 2016 with the clear intent of expanding operations in Wyoming and throughout the US.  As a 60+ year old family owned mineral extraction company, Tosla currently operates in over 90 countries with production and processing facilities in 11 of those countries. With a presence in the US since 2010, the Casper acquisition is the culmination of many years of searching for the right avenue into the US bentonite market. Tosla is very excited about their Tolsa Wyoming Bentonite project and the opportunity to become a member of the Wyoming and national bentonite community. Visit them on the web at for a better understanding of the Tolsa family and the wide array of mineral products they produce and distribute on a global scale.  WMA welcomes Tosla Wyoming Bentonite to the Wyoming mining community!
