About Pacific Minerals Group
40+ years of mining, processing, and delivering premium mineral clays.
Pacific Minerals Group operates one of the few mining sites in the world containing multiple bentonite types in a single deposit. Located in the Mojave Desert outside Death Valley National Park, our clays have been treasured for generations.
Long before commercial mining, the Shoshone and Paiute tribes used these clays for healing, both internally and externally. Today, we serve manufacturers in agriculture, livestock, cosmetics, and construction industries worldwide.
Previously owned by Pfizer, Pacific Minerals Group has maintained an unwavering commitment to quality. In recent years, we consolidated with Protech Minerals, expanding our capacity while preserving the standards our customers expect.
Our clays have been independently researched in private laboratories and university tested. Results prove our superior quality and we are proud to be the supplier for many leaders in the agriculture, pharma-cosmetic, and construction industry. Our mining rights and claims have been grandfathered down for almost a century, and we have no signs of slowing down. We have been fortunate enough to have been blessed with such a rare and unique entity from Mother Nature herself.
We are the proud owner and operators of one of the few mining site in the world that contains multiple types of bentonite, located in the majestic Mojave Desert. Our clays are one of the few alkaline clays in the world to have direct antimicrobial properties, spanning a history of use over hundreds of years, used by Native Americans (Shoshone and Pauite southwest tribes) both internally and externally.
Our sun dried clays are one of the most treasured therapeutic grade clays in the world. It is a magnesium-rich, volcanic-origin smectite clay, harvested from the ground, milled, and mined outside of Death Valley National Park, in the Mojave Desert, California. It is not chemically processed or heat treated in any way, with a pH of between 9.5 and 10.0.
Most recently, Pacific Minerals Group has consolidated with Protech Minerals. We have been fortunate enough to be able to transition all existing customers without issue, continuing to provide premium quality rare earth minerals, consistent quality, and stellar customer service that our customers and clients have come to experience and expect.
